STEM Women on G+104,889We've reached over 100,000 members on STEM Women! To celebrate, we'll discuss how we manage STEM Women, including some of our favourite posts and videos, as well as some of the best comments from you, our followers! We'll talk about what it's like to be women moderators of online science communities. We'll share some tips for other women who want to use social media to communicate their passion for science, and what makes Google+ a special place to share science.This HOA will be hosted by our moderation team: Dr +Buddhini Samarasinghe, Dr +Zuleyka Zevallos and Professor +Rajini Rao. You can tune in on Sunday 7th Sep at 2.30 PM Pacific or 10.30 PM UK/ Monday 8th 7.30 AM AUS.The hangout will be available for viewing on our YouTube channel after the event: http://www.youtube.com/stemwomen#stemwomen #hangoutsonair #hoa100K Celebration: Behind the Scenes of STEM Women2014-09-07 23:30:0020 
STEM Women on G+104,889Join us for a STEM Women HOA as we speak to Professor Chad Forbes about stereotype threat and its impact on women and minorities in STEM. Chad is a Social Neuroscientist who uses electroencephalography (EEG), functional magnetic resonance imaging (fMRI) and other tools to research the impact of negative stereotypes on individuals.Research shows that girls and boys perform similarly well on maths and other aptitude tests in early schooling. The same goes for minority groups. But because society constantly produces stereotypes such as "girls aren't good at maths" and "people of colour can't succeed in science," some youth internalise this and their confidence is undermined. In experiments, reminding individuals about their minority status leads to a poor test result in comparison to people who aren't primed about stereotypes. Chad's research identifies how stereotypes affect motivation and memory, as well as other biases.Chad will explain how stereotypes may impact on the "leaky pipeline," where girls and minorities drop out of STEM careers. We'll also tackle how to combat stereotype threat.Read more about Chad's research and download some of his scientific articles: http://goo.gl/PCGMWu Learn about his ongoing research into women in STEM: http://goo.gl/2TuHbuThis HOA will be hosted by Dr +Buddhini Samarasinghe and Dr +Zuleyka Zevallos.

Hubble Space Telescope3,362,034The #Hubble Space Telecope is poised to provide us with new images of Comet #ISON as it approaches the inner solar system.  In the coming months, we'll get views of the comet from a perspective only #Hubble can provide.Here's the url to the #ISON  blog:http://hubblesite.org/go/isonThe approach of this comet has generated a lot of excitement, it is going to pass extremely close to the sun and when it does, astronomers tell us this may be among the brightest comets we've ever seen hanging in our night sky.Or will it be a dud?Well, we're going to talk about that and a whole lot more:Is it going to hit us?Where did it come from?How big is it?What's it made of?What's so great about comets anyway?What if it breaks up?  Will the pieces hit us?How can I get a comet named after me?Is Scott's head a comet nucleus?Please join +Tony Darnell, +Alberto Conti and +Scott Lewis as they discuss these and any other questions you can think to ask to some of the planetary scientists working at the Space Telescope Science Institute.We'll have +Max Mutchler , Dr. +Bonnie Meinke and Dr. Jian-Yang Li on hand to tell us what Hubble is expected to see, how it will see it and we'll also go into the topic of comets in general.+Zolt Levay Will also be onhand to discuss recent Hubble images of ISON.Hope to see you there!#hubblehangout_jul17The Hubble Space Telescope and Comet ISON2013-07-17 22:00:52264

Dr. John Cassone11,568Dr. John's July Selectgood content and engagementThese are people I follow, engage with, and suggest for my new followers who want quality people in their stream. I've also included some of my new engagers.This is not a megacircle. People are only added based on good content or my experience engaging with them.Best way to sort and manage your stream:1. add new circle2. follow it in your stream separately 3. engage with those that interest you (good content/interaction)4. cherry pick those you like and make your own circles5. let go of the rest (or put them in a circle that's dialed down on your stream)If you add too many people too often then you will not build meaningful connections which is the point here.Circle Management Basics:1. Circles control who you follow:> I might feel like reading the news so I have a news channel circle. I don't build relationships with these pages but follow them and share content when interesting. This way I can completely control my stream based on my mood.2. Circles control who your share to: > Share to your interests: I like martial arts but most of my followers do not. By collecting a circle of others that like martial arts I can share specifically to those interested in this topic and not bore anyone.> I have also collected an "inner circle" of g-peeps that I have gotten to know and share more person pics and info with.3. Control your stream flow:> When you click on a specific circle in your stream you can adjust how much the posts from that circle appear in your "everything" stream. > Organize people based on flow: I have three main circles called 1, 2, and 3. I have the amount of flow dialed in priority (circle 1 is high, 2 is medium, and 3 is low). I move people between circles based on the progression of our relationship. > Notify circle: I have another circle with people that I don't want to miss a single post from. This circle is set to notify me whenever someone from it posts. This is a great way to focus on building a relationship with specific people.Happy Plussing :)2014-07-13 19:18:1119017315

Jean-Marc Luna36,938My buddies (432/1)of the G+ villageI am happy to share (finally) my first big circles (432/1 and 432/2) with you. It is also a way to thank you and to inform you of my consideration.You will find in these two circles all the people I follow regularly since my first steps on Google+ and which accompany me for soon two years in this beautiful adventure, bringing every day, by their sympathy, their humor, their knowledge, their generosity and their open-mindedness, a bit extra to my everyday life.I do not know everybody, I have crossed the path with some, I communicate more with some and many people became friends, thing which I did not expect by landing here.When I began, I was lucky enough to discover new interesting people, thanks to the system of circles sharing, and I hope that these both will be for you of the same utility.If you add a “plus”, maybe it will have an impact on climate change,if you share this circle, maybe Putin is going to get married with an ukrainian women in 2014,if you include me in your circles, maybe it will solve the problem of hunger in the world,Maybe ... but in fact, nothing is sure ;)A good day to all :)With a special thought for #dirktalamasca   #sharedcircles   #circles   #circlesharing  2014-03-31 15:25:36432622658
Daniel Mihai Popescu41,745I do not remember why I have called this circle Zero when I gave it this final form. Anyway, it's a circle of value, it's not a "push". So, don't feel obliged with anything. A "+1" will be greatly appreciated.Thank you very much! #danielmihaipopescusharedcircle   #maximumperformance  I still have some great difficulties to connect properly to G+, so I hope that you understand that.

The Fires of Hatred

This is one of those posts that I'm not sure I should publish, because it's personal, and the topic is complicated, and I don't feel that I have the historical/political expertise to do this any justice. But staying silent is harder so...here goes.

I am a Sri Lankan citizen, and I am ethnically a Sinhalese. A few years ago, Sri Lanka ended a brutal civil war that some of you may have heard about on the news. Sometimes I get asked about the war in Sri Lanka, and what it was like growing up with it. Answering that question is always hard for me. I suspect it's hard for a lot of people in my position, because the answer, the right answer, consists of a lot of words, and the person asking the question tends to want answers in the form of an easily digestible summary: "well, you have your Nazis on the one side, doing bad things like killing... mehr »

Nature Vs Nurture: Girls and STEM

I've been quiet on G+ these past few weeks because I've been busy on a number of different projects but I am so happy to share this article that was published on Nature blogs today. +Zuleyka Zevallos, +Rajini Rao and I worked on this together. 

One of the recurring themes I've seen from doing the +STEM Women on G+ stuff I do is the tired old argument of how women are simply not interested in STEM subjects, and we should all give up on trying to advocate for equality in these fields.

In this article we highlight the many societal pressures that result in the current gender imbalance in STEM, and link to lots of studies that emphatically show how the problem is nurture, not nature. We explain the concept of 'Stereotype Threat', and how the socialisation of girls at a young age, followed by the unwelcoming academic culture is enough to put many women off from pursing STEM subjects.

Is Engaging in Science Outreach Damaging to Scientists?

A few years ago, I started posting about science publicly on Google+. I did it in my spare time because as a scientist, it was obviously a topic I was interested in. I also found the public ignorance about science particularly depressing. This, coupled with a woeful misrepresentation of science on the part of many science journalists on popular media meant that even if the public cared enough to read about science, they would be ill-informed by sensationalised over-hyped articles. There was only one solution, as I saw it - the scientists themselves should engage directly with the public. This has always been my personal motto when it came to doing science outreach (http://goo.gl/Ts8oYf and http://goo.gl/W1XKHT).

Is Engaging in Science Outreach Damaging to Scientists?

A few years ago, I started posting about science publicly on Google+. I did it in my spare time because as a scientist, it was obviously a topic I was interested in. I also found the public ignorance about science particularly depressing. This, coupled with a woeful misrepresentation of science on the part of many science journalists on popular media meant that even if the public cared enough to read about science, they would be ill-informed by sensationalised over-hyped articles. There was only one solution, as I saw it - the scientists themselves should engage directly with the public. This has always been my personal motto when it came to doing science outreach (http://goo.gl/Ts8oYf and http://goo.gl/W1XKHT). 

So it is with dismay that I read this 'joke' article on Genome Biology by Neil Hall (http://goo.gl/oX52dI). In it, he defines the K-index (Kardashian Index) as:

“a measure of discrepancy between a scientist’s social media profile and publication record based on the direct comparison of numbers of citations and Twitter followers.”  A high K-index indicates that the scientist may have built their reputation on a shaky foundation, while a low K- index indicates that the scientist is not being given credit where credit is due.

An unfortunate consequence of the K-index is that it is damaging to other scientists who genuinely engage in science outreach on social media. Scientists are evaluated by their publication records. People who have a low K-index will likely be older and well-established. Someone who started publishing 30 years ago and just joined Twitter will have a very low K-index. On the other hand, early career researchers who haven't published a lot but engage in outreach can appear to have a high K-index. The author also advises people that "if your K-index gets above 5, then it’s time to get off Twitter and write those papers". Never mind that only 1% of scientists regularly publish one paper a year (http://goo.gl/yvd1Yv). Do we really want the other 99% of scientists to stop writing about science on social media?

I understand that this paper was 'semi-serious'. I understand that there are certain science outreach 'personalities' on social media who regularly over-estimate their popularity and importance. But I can already imagine how this index can be used to patronise young researchers who engage in outreach. I can imagine the smirks from senior scientists at job interview panels and evaluation committees. 

This 'joke' article is only funny if you are a senior tenured professor with lots of papers and yet have a low follower count on social media. "Ha ha, let's laugh at those silly scientists doing social media outreach when they should be writing papers!" The K-index trivialises those of us who work hard to communicate science with the public. 

I don't earn anything from doing outreach. It doesn't benefit me professionally. I don't have better job prospects because I have an audience. I do it because as a scientist, I feel I have a duty to directly engage with the public. Doing outreach doesn't harm me either. I hate to think that someday, it might. I hate to think that I might be taken less seriously because I do this. I especially hate to think that other young researchers might be discouraged from engaging in outreach because of this. 

Thanks to +Tommy Leung for the discussion that inspired this post.

Cambridge Delights

There is a quaint little ice cream stand attached to a bicycle that can be found around Cambridge. Jack's Gelato has very quirky flavours, my favourites so far being Earl Grey Tea and Jordanian Orange Flower. This afternoon they were at a farm shop so it was nice to sit under the trees and enjoy some ice cream. 

Trying this again because mobile app is being a pita.

Egg-cellent breakthrough in Parasite Research

There is a recent paper in PLOS Pathogens ( #OpenAccess ) which represents a really interesting development in parasite control. You can read the full paper here: http://goo.gl/E06mMo

✤ Schistosomiasis is a disease caused by parasitic worms of the Schistosoma genus. It affects over 200 million people worldwide, and kills an estimated 300,000 people each year.

✤ Currently there is only one drug (Praziquantel) to treat infections caused by all the different species of Schistosoma. Use of this drug does not prevent reinfection and is not effective against juvenile worms. Understandably, the development of drug resistance is a big worry. Therefore any alternative methods for controlling infections would be very useful.

Egg-cellent breakthrough in Parasite Research

There is a recent paper in PLOS Pathogens ( #OpenAccess ) which represents a really interesting development in parasite control. You can read the full paper here: http://goo.gl/E06mMo

✤ Schistosomiasis is a disease caused by parasitic worms of the Schistosoma genus. It affects over 200 million people worldwide, and kills an estimated 300,000 people each year.

✤ Currently there is only one drug (Praziquantel) to treat infections caused by all the different species of Schistosoma. Use of this drug does not prevent reinfection and is not effective against juvenile worms. Understandably, the development of drug resistance is a big worry. Therefore any alternative methods for controlling infections would be very useful.

✤ The life cycle of the parasite is somewhat complex; eggs are eliminated with faeces into the environment, and they hatch under optimal conditions. Once the eggs hatch, the larvae (known as miracidia) swim and infect specific snail intermediate hosts. Once inside the snail they grow further into another larval stage known as cercaria. The cercariae are infective, and are able to penetrate the skin of the human host. Once inside humans, they develop into adult worms, and migrate into the organs to have lots of sexy time. This produces up to 300 eggs per day per reproductive pair.

✤ Obviously, egg production is therefore important in the life cycle of the Schistosoma. Could this be a way to control Schistosome infections? Researchers focused on the mechanism of eggshell development at the molecular level. They found that one of the key proteins involved in eggshell development is Smp14. The gene for Smp14 is the most abundant RNA transcript in sexually mature females.

✤ Remember that generally speaking, DNA makes RNA makes protein (for a more detailed explanation of this pathway, see http://goo.gl/qqOqa5). Preventing the translation of Smp14 RNA transcript into Smp14 protein would therefore be a valid approach for disrupting egg production.

✤ Indeed, this was the case. Inhibiting the production of Smp14 protein resulted in disrupted eggshell formation. The eggs that were produced had severe defects - they had holes on their surface, which resulted in the egg contents 'leaking' out (see image).

✤ By decreasing the number of viable eggs deposited in the environment, it is possible to limit the transmission of the parasites. This work therefore represents a very attractive route for the development of more effective treatments for the disease.

Can Dogs Detect Cancer?

+Nick Kai Nielsen  tagged me about a recent article on the Guardian about a story where a woman's assistance dog detected her breast cancer (http://goo.gl/WXkfJj). The story is remarkable.

"One evening in November 2011, I was at my computer when Mia leapt on to my lap and nuzzled into the flesh at the top of my left breast. She closed her eyes and licked furiously. That frightened me because it's what she does when I have a bruise or cut. I had an ultrasound within a week and, sure enough, there was a lump that a biopsy later confirmed was grade 2a breast cancer"

Cancer detection through dogs is not unheard of. What is the theory behind this approach? We know that dogs have extremely sensitive noses, and it has been reported that bloodhounds have upto 4 billion olfactory receptor cells, compared to just 5 million in a human.... mehr »

Can Dogs Detect Cancer?

+Nick Kai Nielsen  tagged me about a recent article on the Guardian about a story where a woman's assistance dog detected her breast cancer (http://goo.gl/WXkfJj). The story is remarkable.

That frightened me because it's what she does when I have a bruise or cut. I had an ultrasound within a week and, sure enough, there was a lump that a biopsy later confirmed was grade 2a breast cancer"

Cancer detection through dogs is not unheard of. What is the theory behind this approach? We know that dogs have extremely sensitive noses, and it has been reported that bloodhounds have upto 4 billion olfactory receptor cells, compared to just 5 million in a human. What this means is that our canine friends can discern the presence of a molecule, even when it is greatly diluted. We also know that cancer cells have abnormal metabolic pathways to generate energy, and it is possible that tumours can give off specific volatile chemicals that could be detected by dogs with extremely sensitive noses. But, we do not yet know what these molecules are, much less if and how they are produced by cancers. Clearly, this is a topic that needs to be researched.

In the UK there is a charity called Medical Detection Dogs (http://medicaldetectiondogs.org.uk/), and a quick search through Pubmed indicates that there are several studies to evaluate the efficacy of this novel detection method. However, they are a bit hit-and-miss, and some of the studies seem poorly designed. I'll summarise a couple below:

In 2013, a retrospective study was carried out (http://goo.gl/CKjPrx) where the dogs were trained to detect ovarian cancer in blood samples taken from patients. They compared patients that had clinical remission after undergoing chemotherapy with healthy controls. Generally, we do not know how many patients will have residual cancer cells after complete clinical remission is declared. We also do not know if the dogs were detecting residual chemotherapy drugs in the patient blood samples, or actual cancer cells. I am struck by how the study design did not include another control where the patients were diagnosed with cancer but had not undergone chemotherapy yet, to ensure that the dogs actually detected cancer as opposed to chemo drugs.

Another study looking at prostate cancer (http://goo.gl/KKg5gQ), used dogs that learned to positively identify prostate cancer samples from controls. But when the dogs were tested under double-blind conditions (where neither the dog, nor the handlers, nor the scientists know which samples belong to the control group vs the test group), they did not identify prostate cancer samples more frequently than expected by chance. The study warns that "it is possible that the dogs may memorise the individual odours of large numbers of training samples rather than generalise on a common odour". 

As tempting as it is to look at stories such as the Guardian article with optimism, it is critical to approach them with a degree of realism. These are anecdotal stories. Compelling yes, but still anecdotal. 

There are so many questions we still need to answer: 

✤ Are there molecules produced by cancer cells that can be detected by dogs? 
✤ How is it produced by the cancer cells? 
✤ Can dogs actually smell it? 
✤ Can the dogs be trained to indicate that they smell it? 
✤ How reliable are the dogs at smelling it? 

Until this approach has been rigorously tested, we cannot abandon traditional cancer screening and detection programs in favour of cancer sniffing dogs.

The Fires of Hatred

I am a Sri Lankan citizen, and I am ethnically a Sinhalese. A few years ago, Sri Lanka ended a brutal civil war that some of you may have heard about on the news. Sometimes I get asked about the war in Sri Lanka, and what it was like growing up with it. Answering that question is always hard for me. I suspect it's hard for a lot of people in my position, because the answer, the right answer, consists of a lot of words, and the person asking the question tends to want answers in the form of an easily digestible summary: "well, you have your Nazis on the one side, doing bad things like killing unicorns, and the daring pure-hearted heroes on the other saving those unicorns with their laser-beams" If it took less than five minutes to explain, it's all bullshit, no matter which side of the story you're hearing. Not to mention the fact that the person asking the question usually doesn't have a clue about the ethnic and geopolitical background that led to the whole mess, because who really cares about a tiny island in the middle of the Indian ocean?

But here is a simplified background on what happened, over thirty years ago.

So there is this country, Sri Lanka. Most of the people there are Sinhalese. Less people are Tamil. After becoming a semi-proper democracy back around 60 years ago, the majority Sinhalese began the standard democratic practice of treating the minorities like shit. Not nearly as badly as white America screwed over black America, I mean, we're not barbarians, but still there were some major disparities. So eventually, about 30 years ago, a small group of Tamils decided enough was enough, and made a fuss. A couple of soldiers died in that fuss. The Sinhalese population thought that was rather bad form, and rioted. Much chaos ensued, many Tamil-owned houses were burned to a crisp (sometimes with Tamils in them), and a lot of Tamils had to flee the country for their lives.

In the ensuing 30 years, a war was waged that resulted in a massive loss of life on both sides. It's difficult for me to explain how I feel about this part in an unbiased manner because seeing the results of a suicide-bombing first hand tends to hamper one's sympathy for the cause espoused by the bomber, as I'm sure you'll understand. Either way, the bloody war drew to an end a few years ago, with Sri Lanka declaring loud and proud that they truly 'defeated terrorism'. The loudest and proudest voices were of course, the Sinhalese Buddhists.

Since the End of the War, the Sinhalese Buddhists have become even more xenophobic than before. A few of them, led by Buddhist monks no less, have organised themselves into Sri Lanka's version of the Ku Klux Klan known as The Bodhu Bala Sena (BBS). They are on the brink of instigating yet another civil war. History is repeating itself, except this time it is the Muslims that are being targeted, since the 'Tamils' have already been 'defeated'. 

Why am I writing about this now? Last weekend, Aluthgama, a small town on the southern coast of Sri Lanka witnessed riots. Several people have been killed, and many more injured. The town is burning, and a curfew is in place. The people are running out of food because of the curfew, and the BBS is blocking any food parcels being sent in. The police are apathetic observers at best, because they are mostly Sinhalese Buddhists. Ignoring the violence is a matter of policy. The politicians are staunchly pro-Buddhists and racists against the Muslims. It is a jungle out there, and the violence is escalating. This incident is but one in a long series of events that rarely get reported on because of the atmosphere of silence. But disturbing snippets leak out. YouTube has a speech in which the leader of the BBS (a Buddhist monk) is heard saying that if even one 'marakkalaya' (a derogatory Sinhala word for Muslim) so much as laid a hand on a Sinhalese, that it would mean the end of all of them (Bodu Bala Sena Meeting - Aluthgama). The speech, in Sinhalese, makes me shiver because it is so reminiscent of the type of rhetoric that precedes communal and ethnic war. The sort of people who listen to racist priests and politicians.

The media in Sri Lanka is predictably silent. The 'adults' are predictably silent. The old hatred runs deep. But it is heartening to see commentary on social media condemning these incidents. I have seen many of my Sri Lankan friends, speak out against these events. Perhaps there is still hope. To paraphrase another article on this topic, it feels like "the war never ended, we just took some time off" (http://goo.gl/jpZFFe)

Pulling a Fast One on Cancer

There is a report making the rounds on social media that really needs to be explained, because as usual the media hype is distorting the findings. The article in question was published in the Cell Stem Cell journal, and is #OpenAccess (http://goo.gl/pnoiwa). I will explain the background, what these results mean, and more importantly, what they don’t mean.

✤ Traditional chemotherapy is toxic to cells. The only reason traditional chemotherapy works is because it kills cancer cells faster than it kills normal cells. The side effects from chemo often happen because normal cells are also affected. One such side effect is the suppression of the immune system. This happens because chemo damages adult stem cells too, which impairs tissue repair and regeneration.

The side effects from chemo often happen because normal cells are also affected. One such side effect is the suppression of the immune system. This happens because chemo damages adult stem cells too, which impairs tissue repair and regeneration. 

✤ Blood stem cells (known as hematopoietic stem cells) are responsible for replacing our blood cells; these reside in the bone marrow. In this study, scientists investigated the effect of prolonged fasting on hematopoietic stem cells.

✤ Mice used in this study were fasted for 48 hours, which the scientists defined as prolonged fasting. These mice received no food, only water. They then treated the mice with cyclophosphamide, a common chemotherapy drug. They found that cycles of prolonged fasting reduced the damage caused to hematopoietic stem cells when the mice were treated with cyclophosphamide. They also found that prolonged fasting cycles promoted the regeneration of blood cells through the protection of hematopoietic stem cells. 

✤ Next, the scientists tested whether the effects of prolonged fasting were independent of the toxic side effects of chemotherapy. Could prolonged fasting alone stimulate hematopoietic stem cells to self-renew? Indeed, it could. 

✤ What is the molecular mechanism for this process? A growth factor known as Insulin-like Growth Factor-1 (IGF-1) seemed to be involved. Growth factors are proteins that control the multiplication of cells. To examine this mechanism, the scientists used mice that were deficient in IGF-1.  If you’re curious about how these ‘knockout mice’ are generated, read http://goo.gl/jdbqbk. When these IGF-1 deficient mice were treated with cyclophosphamide, they showed similar results to the prolonged fasting mice; reduced levels of hematopoietic stem cell damage. So getting rid of IGF-1 induced the same protective effects on hematopoietic stem cells.  

✤ How does IGF-1 signalling protect hematopoietic stem cells? They found that the activity of an enzyme known as PKA was also reduced in these prolonged fasting/IGF-1 deficient mice. PKA controls the pathway involved in stem cell regeneration. So inhibiting IGF-1 or PKA signalling mimics the effect of prolonged fasting; it promotes the regeneration of hematopoietic stem cells, thereby reducing the immuno-suppressive side effect of chemotherapy. 

✤ This is really interesting data - this research has identified one of the signalling pathways in the intricate network of reactions controlling the behaviour of hematopoietic stem cells. The mechanism involves PKA and IGF-1 signalling.  

WHAT THE DATA DOESN'T SHOW

What this doesn't show is that fasting is magically a cure-all for cancer. There isn't a single study that shows lowered incidence of cancer in human populations that fast regularly. The fasting that these mice underwent also did not include the feasting that goes on every night as seen with human populations either. The scientists also conducted a small Phase I clinical trial in which patients undergoing chemotherapy fasted for 72h - the results are promising; their hematopoietic stem cells were protected when compared with the non-fasting control group. But obviously more data is needed, and it is highly inadvisable to fast before undergoing chemo, without the explicit guidance of a physician.

To summarise, fasting is not a cure for cancer. If anything, fasting does "cure" everything, eventually; this pathway involves a mechanism known as ‘death’. 

Image: fasting causes a major reduction in white blood cells followed by their replenishment after refeeding. These effects of prolonged fasting can result in the reversal of chemotherapy-induced immunosuppression.

The Cancer-resistant Blind Mole Rat: Clues from the Genome

Although the Naked Mole Rat and the Blind Mole Rat have similar sounding names, they are not close relatives. The two species diverged over 70 million years ago, and blind mole rats are more closely related to rats and mice than to naked mole rats. But both these species are resistant to cancer; in over 40 years of studying blind mole rats, not a single spontaneous tumour was recorded among thousands of captive animals. Intriguingly, the two animals have evolved this resistance independently. Studying the mechanisms for cancer resistance in these two animals can therefore provide a deeper understanding of how cancer arises at the cellular level. The recent publication of the blind mole rat's genome sequence (http://goo.gl/CxlnDH) provides some intriguing hints about these mechanisms.

The Cancer-resistant Blind Mole Rat: Clues from the Genome

Although the Naked Mole Rat and the Blind Mole Rat have similar sounding names, they are not close relatives. The two species diverged over 70 million years ago, and blind mole rats are more closely related to rats and mice than to naked mole rats. But both these species are resistant to cancer; in over 40 years of studying blind mole rats, not a single spontaneous tumour was recorded among thousands of captive animals. Intriguingly, the two animals have evolved this resistance independently. Studying the mechanisms for cancer resistance in these two animals can therefore provide a deeper understanding of how cancer arises at the cellular level. The recent publication of the blind mole rat's genome sequence (http://goo.gl/CxlnDH) provides some intriguing hints about these mechanisms.

✤ The blind mole rat lives underground. Life underground requires several evolutionary adaptations. Of these, one of the most remarkable is its adaptation to low oxygen (highly hypoxic) environments found in underground burrows; O2 as low as 7.2% and CO2 as high as 6.1% have been reported. Low oxygen environments are also found inside tumours, and tumours are able to survive this environment through mechanisms I have explained here: http://goo.gl/8LWVXq

✤ Hypoxic environments typically cause cells to undergo apoptosis - a type of programmed cell suicide. This process is regulated by an important protein known as p53 (see here for more information about apoptosis and: http://goo.gl/lYJRdm). Hypoxia-induced apoptosis would be disastrous for an underground-dwelling blind mole rat, so their p53 protein has a mutation that prevents the induction of apoptosis. Even more interestingly, this mutation is almost identical to a similar p53 mutation found in many human cancers. Both mutations seem to encourage the cells to stop dividing, rather than to self-destruct.

✤ Understandably, the massive loss of cells due to hypoxia-induced apoptosis is undesirable for the blind mole rat, so the p53 mutation can be explained that way. But mutant p53 also means cancer, as many human cancers have a similar mutation. It sounds counter-intuitive that a cancer resistant animal has nearly the same mutation that actual cancers do. How does this work? Clearly, the blind mole rat has other mechanisms in place to compensate for this 'weakened' p53 status. But what are they?

✤ Instead of apoptosis, the blind mole rat relies on a different mechanism for guarding its cells against cancer. This mechanism is necrotic cell death; messier than apoptosis, it is a mechanism that involves the immune system and inflammation. The genome sequence of the blind mole rat has an extra copy of the gene Ifnb1 which encodes a protein known as interferon beta 1. In comparison, the mouse, rat and naked mole rat genomes have only one copy of Ifnb1. The blind mole rat has extra copies of this gene, which results in extra amounts of this protein, leading to a stronger necrotic cell death response. This compensates for the 'weakened' p53. Supporting this hypothesis is the fact that several other genes from the interferon signalling pathway, along with other genes that regulate cell death and inflammation are also expanded in the blind mole rat genome, indicating that this immuno-inflammatory response is heightened in the blind mole rat.

✤ In summary, the blind mole rat genome has acquired a mutant version of p53 (i.e. weakened) as an adaptation to underground hypoxic conditions. This would normally lead to a lowered ability to resist cancer, as p53 is vital for tumour suppression. Therefore as compensation, the blind mole rat genome has extra copies of genes involved in necrotic cell death in order to remain cancer resistant.

✤ It might seem a bit disconnected to study an underground dwelling blind mole rat that is so different from us, in order to understand our own cancers. But as these findings show, understanding the evolution of cancer resistance mechanisms can increase our knowledge of cancer; with this knowledge comes the power to someday develop therapies against cancer, or measures for cancer prevention.

Searching for Sugar Man

If you watch just one documentary this year (or month, or week -depending on how often you watch them), make it this one. In the late 1960s, amidst the height of the apartheid in South Africa, a bootleg recording of an album titled 'Cold Fact' by a mysterious American artist known as Rodriguez suddenly became a phenomenon. But his album failed miserably in America, and there were rumours about a gruesome onstage suicide - one in which he set fire to himself. After that, he disappeared into oblivion. But two South African fans turned into musical detectives to find out more about what really happened to him. The story is incredible, with an unbelievable plot-twist.

The Boring Parts of Science

A recent conversation with a friend brought up a topic I've been thinking a lot about - science communication using social media. It was sparked by seeing a tweet from a science communicator who asked the question "are science communicators who only discuss science that boring in real life, or is it a choice?".

The Boring Parts of Science

A recent conversation with a friend brought up a topic I've been thinking a lot about - science communication using social media. It was sparked by seeing a tweet from a science communicator who asked the question "are science communicators who only discuss science that boring in real life, or is it a choice?".

140 characters isn't nearly enough to discuss this topic, but it did make me consider how I feel about this. Bear with my jumbled thoughts as I attempt to sift through them.

First, scientists are real people - this means we have personal lives outside of our work. We have hobbies, interests, pets and families. We frequently write about our gardens, our culinary adventures, our personal trials and our accomplishments. Part of the challenge that comes with making science accessible to the public includes making scientists themselves accessible to the public. Scientists are not alien, unreachable creatures, isolated in the ivory tower, hiding away in a laboratory peering down a microscope. I mean, sure, we do that, but that's not all we do. 

The question of how much of that 'other stuff' we choose to share on social media with the public obviously varies on a case by case basis. When I choose to follow someone like Neil Shubin or Carl Zimmer, it's because I am genuinely interested in reading what they write about their area of expertise - I really don't care to know what they ate for breakfast that day. I'd much rather learn about a new species of Amazonian catfish than see a hasty photo of their half-eaten breakfast bagel. I am not bored reading about science, assuming of course that the author knows 'how to write good' :P

I understand and agree with the importance of showing the other side to our personalities, as it ‘humanises’ us as scientists. Whether this is a conscious decision or a subconscious side-effect depends on the individual - some people just write whatever because “eh who cares”, while others coldly calculate 'social media strategy' because they view it as a job. The problem I see with labelling the 'science posts only' approach as boring is the implicit message that science is boring. It's not! It's fantastic and exciting and humbling, and there is absolutely no monotony to break up with forced personal oversharing. Worse, it gives the impression that science must be truly boring if even scientists themselves say it's boring. Again, not true. 

I want to finish by sharing this excellent comic by Cyanide & Happiness. Science includes the study of tedious little details, not just the flashy newsworthy bits made of up memes and pretty pictures. Most of the time there is rage and frustration that comes from doing science. I've lost track of how many empty gels I've seen that had me forlornly asking an empty darkroom in the middle of the night 'Y U NO AMPLIFY?!'. It's part of the weird, twisted charm that science has, that makes those rare victories all the more rewarding when they happen. Sharing that with the world is what makes science, and therefore myself as a scientist, accessible. 

I know I am biased, but I stand by it; science is not boring and scientists are not boring.

The Eighth Hallmark of Cancer is defined as "Tumor-Promoting Inflammation". All seven previous Hallmark articles can be found here: http://goo.gl/IDGfLp

As always, because this is such a complex topic, I don't want to skip details at the cost of avoiding TL;DR. So I've written a far more detailed explanation (complete with my own diagrams!) that is easier to follow on +Scientific American, and I highly recommend you check it out here: http://goo.gl/ThMpl9. In this article, I explain the complex relationship between inflammation and cancer, and how our own immune system can 'turn traitor' and promote cancer development.

✤ Within the last few years, we have obtained clear evidence that inflammation plays a critical role in cancer development, and we are just beginning to understand the molecular mechanisms of how this happens. Chronic infections, obesity, smoking, alcohol consumption, environmental pollutants and high fat diets are now recognized as major risk factors for most common types of cancer; and, importantly, all these risk factors are linked to cancer through inflammation. 

✤ Inflammation is how tissues and cells respond to injury. If the inflammation causing agent persists for a prolonged period of time, the body’s response to it becomes a chronic inflammation. Chronic inflammation increases cancer risk. 

✤ An extremely graphic yet apt way of describing a tumor is as “a wound that doesn’t heal”. Indeed, there are many similarities between a cancerous tumor and the process of wound healing. Both involve the growth, survival, and migration of cells; both require the growth of new blood vessels; importantly, all these processes are controlled by growth factors and signalling molecules. Just as the immune cells gather near a site of injury to secrete growth factors to begin tissue repair, tumors can also surround themselves with immune cells that secrete these same growth factors to promote their uncontrolled cell growth. 

✤ Tumor Associated Macrophages (TAMs), a 'corrupted' type of immune cell support tumors in four different ways; by providing growth factors, helping to develop a blood supply to the tumor, promoting metastasis and suppressing the tumor-killing abilities of the immune system. Essentially, TAMs help the tumor overcome the barriers represented by the anti-cancer defence mechanisms that consist the Hallmarks. 

✤ The existence of both tumor-promoting and tumor-killing immune cells at first seems counter-intuitive. The immune cells specializing in wound cleaning and clearing up dead cells are recruited and subverted by tumor cells to support tumor growth and progression. Shifting the balance from tumor-promoting to tumor-killing immune involvement therefore represents an attractive and powerful possibility for future therapy.

"Tobacco Killing Cancer": Say it Ain't So

There's a new research finding making the rounds on sensationalised mass media with breathless headlines about how a molecule from the tobacco plant can 'explode' and kill cancer cells. The work is actually very interesting, but as usual the #ScienceMediaHype  is not warranted. So what is it all about?

✤ Scientists were looking at a molecule isolated from the flowers of the ornamental tobacco plant Nicotiana alata. This molecule, named NaD1 derives its name from Nicotiana alata defensin 1. NaD1 is part of a group of molecules known as defensins, which are really interesting in their own right.

✤ What are defensins? They are small protein molecules found across many different species of animals and plants. As their name implies, these molecules function as part of the host innate immune system; they have anti-microbial activity against bacteria, viruses and fungi. As a general rule, defensins bind to the cell membrane of the microbe causing changes to cell membrane structure, allowing essential ions and nutrients to leak out, thereby killing the cell. However, the exact mechanism by which defensins bind to the cell membrane has been unclear up until now. 

✤ In this study, scientists identified that the defensin NaD1 binds to a small phosolipid (a lipid molecule with a phosphate molecule attached to it) known as PIP2. This binding results in a NaD1:PIP2 complex which they visualised using transmission electron microscopy. NaD1 is able to polymerise and form long string-like structures in the presence of PIP2. This binding is crucial for NaD1's microbe-killing abilities.

✤ Next, the scientists tested the ability of NaD1 to cause changes in the cell membrane. They used a dye that normally does not cross the cell membrane to monitor cell membrane integrity; if the dye shows up inside the cells, the cell membrane is obviously damaged. Sure enough, NaD1 caused an influx of the dye into the cell, and also leakage of ATP molecules from the cell to the outside. Using scanning laser confocal microscopy, the scientists then visualised the effect of NaD1 on HeLa (cervical cancer) cells. The membrane blebbing (protrusions) and intake of the red dye can be seen in the gif below.

✤ Since PIP2 is found in many different cell types, the scientists also evaluated NaD1's cell membrane destroying capabilities in many different cell types. They found that immortal cells (i.e. tumor cells) were more susceptible to killing by NaD1 than normal cells. This is attributed to the different properties that cancer cell membranes have when compared against normal cell membranes, and the precise mechanism for this is yet to be discovered

✤ Defensins are really interesting molecules with a whole range of functions. In this study, scientists identified the precise mechanism by which NaD1 destabilises the cell membrane by specifically binding to PIP2. They are capable of forming oligomers to carry out diverse functions within the immune system, and this study explains in detail one such mechanism. This is fascinating in its own right, and does not need to be labelled with a ridiculous 'tobacco plant can cure cancer' label to make it newsworthy!

"Exploding Cancer Cells" Explained

By now many of you may have seen reports of a new 'breakthrough' in cancer research resulting in 'exploding cancer cells' (http://goo.gl/MT1j7z). These reports are in reference to a new study published in the journal Cell. What exactly does this mean, and how realistic is it to expect this treatment to reach patients anytime soon?

✤ In this study, scientists focused on a very aggressive, essentially incurable type of brain cancer known as glioblastoma. Glioblastomas typically have a lot of things wrong with it, meaning most of our inherent hard-wired cellular defense mechanisms (http://goo.gl/fFw7xP) have been overridden. Even worse, glioblastomas tend to harbor a subset of cells known as 'cancer stem cells' that are resistant to treatment and can repopulate the tumor following treatment(... mehr »

"Exploding Cancer Cells" Explained

By now many of you may have seen reports of a new 'breakthrough' in cancer research resulting in 'exploding cancer cells' (http://goo.gl/MT1j7z).

✤ In this study, scientists focused on a very aggressive, essentially incurable type of brain cancer known as glioblastoma. Glioblastomas typically have a lot of things wrong with it, meaning most of our inherent hard-wired cellular defense mechanisms (http://goo.gl/fFw7xP) have been overridden. Even worse, glioblastomas tend to harbor a subset of cells known as 'cancer stem cells' that are resistant to treatment and can repopulate the tumor following treatment (http://goo.gl/qwHFOL).

✤ The scientists screened a range of compounds for their ability to specifically kill glioblastoma cells in culture (i.e. grown in a petri dish). They identified a compound they named Vacquinol-1 which was highly specific; it had no effect on other types of cells, only glioblastoma cells.

✤ Next, they were curious about the mechanism of cell death and discovered that the cells did not die through apoptosis, i.e. the cell suicide program. However they did find that the cell membranes rapidly changed their shape when treated with Vacquinol-1, indicating that the process had something to do with endocytosis.

✤ Endocytosis is a process by which small molecules are brought into the cell from the outside. The cell membrane forms an invagination (crater-like cups), and the molecules are enclosed in a vesicle (a small bubble) within the cell. When glioblastoma cells were treated with Vacquinol-1, they observed the rapid rounding of cells, the formation of spherical protrusions and irregular bulging of the cell membrane, followed by eventual rupture of the cells through a necrotic-like cell death mechanism. This is the part that has been likened to 'exploding cells'.

✤ Next, in order to fully understand the cellular signalling mechanisms involved, they looked at which genes are involved in this process of cell rupture. They identified a gene known as MKK4 which is involved in many cellular processes such as growth, inflammation and apoptosis. Although the exact mechanism of this pathway is yet to be identified, when MKK4 is missing, Vacquinol-1 had no effect on the cells, indicating that the MKK4 gene is required for this process.

✤ All this was done in petri-dishes so next they tested Vacquinol-1 on mice that had glioblastomas and found that the compound significantly reduced the size of the tumors. The mice in the control group had a median survival (i.e. half the mice were dead) of 31.5 days. In contrast, only two of the eight Vacquinol-1-treated mice died during the 80 days of the experiment. Clearly, the compound had a very pronounced effect on survival.

✤ Clearly there is a long way to go with this work, which is very promising. But it is important to remember that this has only been done in a petri-dish, zebrafish and mice. It hasn't been tested in humans. Pre-clinical trials are a while away yet, and while it is tempting to get excited about the idea of 'exploding cancer cells', a degree of caution is a must.

The Sex Wars of Ducks

Some of you may have seen this video already, but in case you haven't, it is a strange wonderful narration of duck mating habits by Isabella Rossellini.

Here's a write-up from Nature explaining the phenomenon http://www.nature.com/news/2009/091223/full/news.2009.1159.html

Cancer Signalling: The Wnt Pathway

We are multi-cellular animals, and as such, our cells need to communicate with each other, so they can act in a coordinated manner in response to the environment. The basis of this communication comes from a process known as cell signalling. Various signalling molecules surrounding the cellular environment can stimulate cells to grow and divide at the appropriate time. When these carefully regulated cellular processes go wrong, cancer happens.

✤ The Wnt Signalling Pathway (pronounced 'wint') is one of the most studied signalling pathways in molecular biology.  Discovered over thirty years ago, it is also a pathway that is frequently disrupted in cancer, particularly colon cancer. What is this pathway and how does it work?

Cancer Signalling: The Wnt Pathway

We are multi-cellular animals, and as such, our cells need to communicate with each other, so they can act in a coordinated manner in response to the environment. The basis of this communication comes from a process known as cell signalling. Various signalling molecules surrounding the cellular environment can stimulate cells to grow and divide at the appropriate time. When these carefully regulated cellular processes go wrong, cancer happens.

✤ The Wnt Signalling Pathway (pronounced 'wint') is one of the most studied signalling pathways in molecular biology.  Discovered over thirty years ago, it is also a pathway that is frequently disrupted in cancer, particularly colon cancer. What is this pathway and how does it work?

✤ In Wnt signalling, the key effector is a molecule known as beta catenin. Under normal circumstances (when Wnt signalling is not active) beta catenin is constantly made by the cell and constantly destroyed. A new molecule of beta catenin only lasts in the cell for about 5 minutes before it is destroyed. However when Wnt signalling is active, this destruction is halted, so that beta catenin accumulates within the cell. Once beta catenin levels reach a certain threshold, it moves into the nucleus, binds to DNA and activates other genes that go on to promote cell division.

✤ One of the most common mutations in colon cancer is a gene known as APC. APC is part of the protein complex that destroys beta catenin. When APC is mutated, beta catenin cannot be destroyed; it accumulates in the cell and causes uncontrolled cell growth. It's like a car with no brakes. It can lead to the development of hundreds of polyps in the colon as illustrated by the picture below. Although benign at first, these polyps can turn cancerous if left untreated. Unsurprisingly, people who have mutant APC have a nearly 100% chance of developing colon cancer by the age of 40 years.

✤ What effect does beta catenin activation have on different cells in our body? What are the other components of the Wnt signalling pathway and are there other ways in which beta catenin levels can be regulated by the cell? Can we exploit our knowledge of this pathway to inhibit beta catenin, to develop therapies to treat colon cancer? These are all areas of ongoing research, and there are many exciting new developments in the field of Wnt signalling.

On Sunday March 23, I will be speaking to +Akinola Emmanuel and +shilpa keerthivasan about their recently published research (http://goo.gl/BS2VH8) looking at Wnt signalling in immune cells. Their results are fascinating! You can RSVP to watch it here (http://goo.gl/QzeWAa), and the video will be available on YouTube after the event. 

For a great essay on the history of Wnt signalling, check out this review from the EMBO Journal (#openaccess) http://goo.gl/NE13yu

So far today there has been rain, snow, hail and wind, along with the brightest sunlight and bluest sky I have seen in days. The weather really can't make up its mind! These daffodils didn't seem to mind too much though!

The Story of How I got into STEM

I wrote this article for www.stemwomen.net to coincide with our great Hangout on Air yesterday with +Jonathan Eisen and my awesome co-host +Zuleyka Zevallos :) (if you missed it, you can watch it here: STEM Women: How Men Can Help, with Professor Jonathan Eisen)

In the article, I explain how I first became interested in molecular biology by reading a popular book that was written by a rather anti-science author (oh, the irony!). Can you guess the book? :)

The Secrets of Life: Why I Got Into STEM By +Buddhini Samarasinghe 
Our team is sharing our inspiration for becoming involved in STEM. In this post, Buddhini tells how her passion in molecular biology began in a somewhat unlikely place - after reading a wildly popular novel about DNA cloning... written by an anti-science author no less! (Can you guess the book?)

Buddhini’s tale shows the importance of popular culture in igniting the scientific spark amongst young people. She also demonstrates the central role that parents can play in supporting young girls who have an interest in STEM. Rather than following narrow cultural expectations, Buddhini has turned her scientific curiosity into a career dedicated to research and public outreach.

We'll be bringing you more tales from our Role Models series from our new website! Read Buddhini's post: http://www.stemwomen.net/secrets-of-life/

The Science of Slinky Drops

Watching QI is, without fail, a great way to learn new things that make me go... "Hah that's quite interesting!" (yeah, you saw that coming!). This time Stephen Fry was talking about slinky drops, specifically how the bottom of the slinky does not move when it is released from the top. See the image below.

How does this happen? Unsurprisingly, gravity is involved. When we drop an object, we remove the force supporting it that balances the weight of that object, so that it accelerates towards to ground due to gravity. So far so good. But there are additional forces at play when it comes to a slinky.

The hanging slinky is 'stretched out', or under tension, because of its own weight. The slinky is in equilibrium, so the tension equals the weight. When released, the tension changes, disrupting the equilibrium. This change... mehr »

The hanging slinky is 'stretched out', or under tension, because of its own weight. The slinky is in equilibrium, so the tension equals the weight. When released, the tension changes, disrupting the equilibrium. This change is propagated through each coil of the slinky.

The bottom of the slinky is the last part to experience this change and remains in equilibrium between a downward force due to weight and an upward force due to tension. This is until the change in tension propagates to the last coil. The bottom of the slinky experiences no net forces (equal weight and tension) before, and immediately after release. We know from Newton's First Law of motion that an object at rest stays at rest unless acted upon by an external force. So in the case of the slinky, that is exactly why the bottom of the slinky does not move.

Here's a great explanation of this phenomenon from Veritasium:

Why Don't Naked Mole Rats get Cancer?

Naked mole rats are the most fascinating of creatures. There are many reasons I say this, but today I want to focus on one particular feature about them that is just an amazing example of how weird and wonderful they are. Naked mole rats are extremely resistant to cancer - tumors have never been observed in them. How on earth do they manage this?

✤ Before I explain the exact mechanism, we need to go over some basics. A tumor is an aggregation of cells. Cells generally don't like to be too close to each other - in the lab, if a petri-dish has too many cells on it, the overcrowding makes them stop growing. We call this contact inhibition.

Why Don't Naked Mole Rats get Cancer?

Naked mole rats are the most fascinating of creatures. There are many reasons I say this, but today I want to focus on one particular feature about them that is just an amazing example of how weird and wonderful they are.

✤ Before I explain the exact mechanism, we need to go over some basics. A tumor is an aggregation of cells. Cells generally don't like to be too close to each other - in the lab, if a petri-dish has too many cells on it, the overcrowding makes them stop growing. We call this contact inhibition. The cells sense that they are too close to each other and secrete signaling molecules into their surroundings known as anti-growth factors. These molecules signal the cells to stop dividing. I explained this pathway in detail here: http://goo.gl/BsRgR5. Cancer happens when this mechanism fails.

✤ If cancer happens when contact inhibition fails, then it logically follows that enhanced contact inhibition should mean even more cancer resistance. Bingo - that is exactly what happens with naked mole rat cells. These cells are hypersensitive to contact inhibition, which is what makes them so resistant to cancer.

✤ Our cells also have a mechanism for contact inhibition, and yet we are unfortunately more than capable of developing cancer. This raises the question, what is so special about naked mole rat cells that makes them so hypersensitive to contact inhibition?

✤ It turns out that naked mole rat cells have an additional mechanism to make them hypersensitive to contact inhibition. Our cells rely on a protein known as p27 to halt cell division by putting the brakes on the cell cycle. Naked mole rat cells, on the other hand, use p27 for regular contact inhibition just like we do and another protein known as p16 for early contact inhibition. The naked mole rat cells have the same genes we do (we both have p27 and p16) but their functions are distinct; for naked mole rats, p16 functions as the 'early brake' while p27 functions as the 'backup brake'. There are other differences between our cells and naked mole rat cells, but this is the primary mechanism by which they evade cancer.

I find this work fascinating, not just because it features the awesome naked mole rat, but because it explains the molecular mechanism of why naked mole rats don't get cancer. It also shows how the same genes are capable of vastly different functions in different species; although the naked mole rat's anticancer defense strategy evolved separately to us, our cells carry the same tools.

View from a train window

I was going through my phone and deleting some old photos when I came across this one. It brought back a lot of memories. I took it on the way to Kandy, from Colombo. The views on either side of the train were breathtaking, passing through lush forests and sleepy valleys, past coconut palms and pale blue skies. It's one of my favourite photos, because it reminds me of the adventure of exploring Kandy that day.

Pretty much everyone has seen the fantastic Oatmeal comic about the Mantis Shrimp by now (http://goo.gl/ZgX7pZ). Because the mantis shrimp has such amazingly complex eyes, we assumed that they would see the world around them in an unimaginable array of colors. A publication in the journal Science indicates that this is not the case.

✤ Mantis shrimp eyes have between 16 and 21 different photoreceptor types - in contrast, we have only 3 (green, blue and red). Why does the mantis shrimp need so many photoreceptor types, and what do they do?

✤ Mantis shrimp eyes have between 16 and 21 different photoreceptor types - in contrast, we have only 3 (green, blue and red). Why does the mantis shrimp need so many photoreceptor types, and what do they do?

✤ To answer this question, scientists designed an experiment to test the mantis shrimp's color discriminating abilities. They used a two-way choice test to train the animals to specific wavelengths with food rewards. They presented the choice to the animal using a pair of optical fibers and then they recorded which end was tapped or grabbed by the animal.

✤ So far so good. What the test showed was that when the difference between the test and the trained wavelength was reduced to between 25 and 12 nm, the mantis shrimps could no longer distinguish between the two. The bottom line? Despite having so many photoreceptor types, mantis shrimps have rather poor color vision.

✤ So what's going on? It turns out that mantis shrimp 'see' in a truly remarkable way. They recognize colors instead of discriminating them. The different wavelength sensitivities would be converted to a pattern when scanned across an object, which the animal then recognizes as a color.

✤ What's the benefit of such a system? It allows the mantis shrimp to make a quick and reliable determination of color. Given that mantis shrimp live on shallow coral reefs, some of the most colorful habitats on the planet, this makes sense. They live a fast paced lifestyle, involving combat and territoriality so having a simple, quick and efficient method to recognize colors would be critical for survival.

Outing as a Weapon: Don't be a Dick

I've been on the fence about whether I should write this post or not, but decided to do it because it feels a bit cowardly not to. I have a lot of thoughts about this topic so it's a bit of a muddle; bear with me if they appear jumbled.

Choosing to write under a pseudonym can allow you to write more candidly, but it also gives people power over you, and sometimes this power gets abused. Let me explain.

I used to pride myself on how when I'd Google my name, nothing would show up. However, I've followed science bloggers for years, lurking in the sidelines, consuming their content voraciously all the while never commenting, never dipping my toes in the actual content-creation side of it. I liked being a nobody, and I was happy being anonymous.

I used to pride myself on how when I'd Google my name, nothing would show up. However, I've followed science bloggers for years, lurking in the sidelines, consuming their content voraciously all the while never commenting, never dipping my toes in the actual content-creation side of it. I liked being a nobody, and I was happy being anonymous.

All that changed when I signed up for Google+ in 2011 and discovered a world of fellow scientists and science enthusiasts. I started sharing articles that interested me, and then gradually started writing more original content myself. Thanks to Google's 'real name policy', signing up with anything other than 'Buddhini Samarasinghe' wasn't an option. Now, if I Google my name, tons of stuff that I have written shows up. I am no longer anonymous.

Losing my anonymity came at a price. I am careful about what I say, and how I say it. I can't be as candid as I'd like to be, and I can't swear as often as I'd like to (ha!), because I don't want a future employer to come across anything that might impact me negatively. Those who know me IRL will know that I rein myself in a lot online. I have to think twice before writing about certain topics. I have to watch myself.

There are many writers out there who choose a different path. They write under a pseudonym, and are more able than I am to write freely about whatever topic they wish to write about. The downside is that they have more to lose, because they haven't been self-censoring to the same extent that I have been.

So imagine what an awful thing it is, when someone dislikes you/your writing enough to publicly 'out' who you are and call you out by your real name. Suddenly there is a real name attached to your pseudonym! Suddenly, anyone can find out who your boss is. Suddenly, you have to look back at everything you have written and wonder if it's okay to have those words associated with your real name. Suddenly, you've become the target of everyone's attention, and that attention can have consequences on your private and professional life.

Outing a pseudonymous writer's real name, or any other aspect of their private life, has become a way to bully them into silence. Recall the case of Dr V, who was outed as being a transgendered individual by a journalist, which led to her suicide (http://goo.gl/LWwhAz). More recently, Isis the Scientist, a female scientist and writer who discusses the issues women face in academia was outed by a senior editor at Nature who appears to have had a personal grudge against her. Outing someone has become a way to discredit their opinions. This is not right. I don't know what we can do about it, beyond calling out this sort of behavior for what it is, and trying harder to make other pseudonymous writers feel safe. If you're ever tempted to abuse your position of power over a pseudonymous writer by outing them, don't.

It's a really dickish thing to do.

"There is a tacit understanding, a custom in the culture of science, that scientists practice the scientific method in the confines of the Ivory Tower. Scientists are seen as impartial, aloof, individuals with a single-minded focus on their work and out of touch with the realities of the world around them. Scientists are expected to only do science, to find the truth and then leave it up to everyone else to decide what to do with it"

"This is untenable. Scientists have a moral obligation to engage with the public about their findings; to advise and speak out on policy, and to critique its consequent implementation. Science impacts on the life of every single species on our planet. It is ludicrous that the very people who discover the facts are not part of any subsequent policy-making dialogue. Science needs to be an essential component of the public discourse; currently it is not"

"Sticky Balls" and Cancer Therapy

There have been several reports (http://goo.gl/JkyXkL) of a new 'breakthrough' cancer therapy that uses nanoparticles tagged with cancer killing proteins. What exactly does this mean, and how realistic is it to expect this treatment to reach patients anytime soon?

Let's go over the findings first. 

✤ Scientists at Cornell University first created nanoparticles (in this case, tiny lipid droplets that were measured to be just over 100 nm diameter). Next, they attached two proteins to these nanoparticles.

✤ The first was a protein known as TRAIL. TRAIL is basically a "DIE RIGHT NOW!" signal to any cell that comes in contact with it; it induces a cellular suicide program known as apoptosis (http://goo.gl/AhV95g). The second protein was E-selectin, which is a cell adhesion molecule.Thin... mehr »

✤ Cancer cells have TRAIL receptors on their surface; when TRAIL binds to this receptor, the suicide program is activated in the cell. So the theory is, when cancer cells migrating in the blood stream encounter these TRAIL-bound nanoparticles, they kill themselves. This is important because cancers spread through the blood stream, and the ability to kill invasive cancer cells could dramatically improve patient prognosis.

✤ So the researchers created the TRAIL-bound nanoparticles, and then tested them in human blood that was mixed with circulating tumor cells. They found that the TRAIL nanoparticles were extremely effective at killing the cancer cells.

✤ Since this was just an in vitro experiment (i.e. done in a cell culture dish), next they tested it on a mouse. The scientists injected tumor cells into mice, along with the TRAIL nanoparticles. Again, they showed that the TRAIL nanoparticles were able to kill the tumor cells in the mice.

✤ TRAIL's cancer killing abilities have already been used on patients in clinical trials (http://goo.gl/Hmx0w0). But this is the first time TRAIL nanoparticles were used in this manner, and it is exciting to consider the possibility that these nanoparticles may be able to zap cancer cells into oblivion as they circulate in the bloodstream during metastasis.

✤ BUT, that's still a while away. It is important to remember that this has only been done in a petri dish and in mice. It hasn't been tested in humans. That might be a few more years down the line. For now, it's not available to patients and should not be viewed as a cure for metastatic cancers.

Lost in Translation: British and American backgrounds in Academia

Too good not to share! I read the green column and understand it the red column way. There is no confusion.

However, I struggle with the American approach of self promotional language, where you have to blatantly sell yourself and impress everyone with how awesome you are. I cringed so much when I had to do it in the US! I much prefer the British self deprecating humility, although they too can take it too far sometimes.

Well, kinda. It's grey and barren and yet there is a somewhat desolate beauty about it.

The Mutant Lobster

Last night the BBC had an interesting documentary (Nature's Weirdest Events) which featured a really bizarre creature; the two-colored lobster, split right down the middle where one half was bright orange, and the other half was muddy brown. How does this work?

✤ To understand this, first we need to go over how lobster pigmentation works. Normal lobsters are colored muddy brown. They get their color from their diet as they grow and develop.

✤ Lobsters feed on a diet of shellfish and other organisms, containing the red pigment astaxanthin, an antioxidant compound. It is also the same pigment that gives salmon and flamingos their pink color. So why are lobsters a muddy brown, instead of pink like a flamingo?

✤ When the red pigment is absorbed from the diet, it is laid down into the muscles that lie beneath the shell. Over aperio... mehr »

The Mutant Lobster

Last night the BBC had an interesting documentary (Nature's Weirdest Events) which featured a really bizarre creature; the two-colored lobster, split right down the middle where one half was bright orange, and the other half was muddy brown. How does this work?

✤ To understand this, first we need to go over how lobster pigmentation works. Normal lobsters are colored muddy brown. They get their color from their diet as they grow and develop.

✤ Lobsters feed on a diet of shellfish and other organisms, containing the red pigment astaxanthin, an antioxidant compound. It is also the same pigment that gives salmon and flamingos their pink color. So why are lobsters a muddy brown, instead of pink like a flamingo?

✤ When the red pigment is absorbed from the diet, it is laid down into the muscles that lie beneath the shell. Over a period of time, the pigment migrates into the shell where it is transformed by a protein known as alpha-crustacyanin into a blue color. Later, the pigment migrates even further to the surface of the shell where another protein transforms it again into a yellow color.

✤ It is helpful to think of the lobster shell in terms of three different color filters; first the red muscle, then the blue shell, then the yellow shell. Combining all three forms the typical lobster shell color; the dirty muddy brown. When a lobster is cooked, the yellow and blue proteins degrade while the red astaxanthine is heat-stable, which is why a cooked lobster is bright red.

✤ So how does this explain the mutant two-colored lobster? This lobster was bright orange on one half and normal muddy brown on the other half. Each side of a lobster's body develops independently of the other half. Once the sperm fertilizes the egg, it grows and splits into two cells. This split is important, because it determines how the lobster will develop for the rest of its life. Sometimes when the fertilized egg makes the split into two cells, very rarely there is a mutation in the gene that codes for protein associated with color. As the lobster grows, each cell replicates, and the genetic abnormality on the mutant side will also replicate. So that is how we end up with a lobster split directly in two, with a color mutation on one side. The chances of this mutation has been estimated at 1 in 50 million!

The American Chemical Society has a really good explainer video on the mechanism of lobster colors: The Colorful Chemistry of Lobster Shells - Bytesize Science

What Have You Changed Your Mind About? Why?

Every year, the science website Edge (www.edge.org) has an annual question, which is answered by scientists, philosophers and thinkers. I really like their question from 2008, and I was curious what the G+ world had as a response. Here is the question in full;

When thinking changes your mind, that's philosophy
When God changes your mind, that's faith
When facts change your mind, that's science

WHAT HAVE YOU CHANGED YOUR MIND ABOUT? WHY?

Science is based on evidence. What happens when the data change? How have scientific findings or arguments changed your mind?

WHAT HAVE YOU CHANGED YOUR MIND ABOUT? WHY?

Science is based on evidence. What happens when the data change? How have scientific findings or arguments changed your mind?

For me, the biggest thing I've changed my mind about would be how we report scientific findings. I used to be neutral about the whole Open Access debate. Now? I am fully supportive of efforts to make scientific research accessible to the public. It's more important than ever that we have a scientifically literate society, and we cannot have that if scientists hide in their ivory towers, and research findings trickle down through dumbed-down, misrepresented, sensationalized segments and articles through the mainstream media. Scientists must engage with the public and the wonderful journey of discovery that is science must be shared.

What about you? What have you changed your mind about? Why?

The Value of Repair

This is an extremely thought provoking piece from Aeon Magazine that I read over the holidays. It's about how the ability to repair our material possessions used to be the norm, and added value to them. Now we're moving away from that culture, to a place where 'opening up' a machine can void its warranty. Things have become 'single use' and disposable. I'm not sure if that's a good thing.

"Equally detrimental to a culture of mending is the ever more hermetic nature of technology. DIY fixes become impossible either physically (the unit, like your MacBook lead, is sealed) or technically (you wouldn’t know where to start). Either way, the warranty is void the moment you start tinkering.
