Why You Should Record All Species and Bird Outside Hotspots

by John Beetham in A DC Birding Blog

Accurate species distribution data is necessary to address biodiversity challenges. To save endangered species, conservationists need to know which species populations are contracting or expanding. Restoring an ecosystem requires an accurate picture of how the ecosystem existed historically. Unfortunately, existing global data collections such as the Global Biodiversity Information Facility and IUCN Red List underrepresent some geographic areas, especially in the tropics, and may not show accura........

How strong is the HDL-cardiovascular disease hypothesis?

by Colby in nutsci.org

A lot of nutritional studies, especially epidemiological, rely on certain biomarkers to assess disease risk upon interventions.  Many of these biomarkers are accepted with little challenge, and thus become very common to examine.  Historically, jumping too quickly to conclusions from associations has confined our nation to a nutritional nut-house; people are confused because of mixed [...]...

Obesity May Cost US Boomer Babies $1 Trillion in Lifetime Earnings

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Born between 1982 and 1993, the kids of the Baby Boomers are sometimes also referred to as the Millennial generation, Generation Y, Net Generation, or Echo-Boomers.
This generation has fully embraced social networking (e.g. Facebook) and file sharing (e.g. Napster) and spends an average of 3.5 hours a day online. They have also been noted to [...]... Read more »

Could an RSV vaccine reduce childhood pneumonia in Africa?

by Wellcome Trust in Wellcome Trust Blog

Pneumonia is the leading cause of childhood death in sub-Saharan Africa and while it is well known that many pneumonias are caused by bacteria such as Streptococcus pneumonia – for which vaccines are available – we know less about those caused by viruses. A new study, published in the Journal of the American Medical Association [...]... Read more »

Testing the flotation dynamics and swimming abilities of giraffes by way of computational analysis

by Darren Naish in Tetrapod Zoology





One of the most significant papers ever published in the annals of science appeared recently; it deals, for the first time ever, with one of the biggest scientific questions ever faced by the scientific community, and uses cutting-edge technology and awesome powers of deductive reasoning and logic to reach shocking, paradigm-shifting conclusions. I refer, of course, to Don Henderson and Darren Naish's Journal of Theoretical Biology article 'Predicting the buoyancy, equilibrium and potential ........ Read more »

The homeless man and his audio cave

by BPS Research Digest in BPS Research Digest

We're defined in part by where we are, the places we go and what we do there. We adorn our homes with paraphernalia caught in the net of life - the photos, the books and pictures. But what happens when you're homeless? How do you define your space and identity when your home is a public place? To find out, Darrin Hodgetts and colleagues have conducted an unusual 'ethnographic' case study with 'Brett', a 44-year-old homeless man in Auckland.The researchers gave Brett a camera, asked him to take p........

Bulimia and the Vaso-Vagal Reflex

by Evil Monkey in Neurotopia

This is another post in Sci's investigation into the current studies being performed on eating disorders, particularly binge eating and bulimia. Usually I try to focus on the dysregulation of reward-related systems in these disorders, but this paper will be a little different.

To Metagenome or not to Metagenome

by Daemios in Rudimenthos

A masterpiece of science blogging was posted here (http://suicyte.wordpress.com/2007/11/20/smallest-primate-ever-discovered/), addressing the finding of primate sequences in the GOS dataset, just one of the unassesed ambiguities in metagenomics.The post is beautifully written and made me laugh really loud. The point is that metagenomics is sometimes being overselled just in the very same way as genomics has been (see Eisen's blog for just some examples) and this leads to an skeptic counterwave........

Pesticides Linked to ADHD: Salad with a Side of Suspected Toxins

by Polly Palumbo in Momma Data

I try to buy organic fruits and veggies, at least the dirty dozen.  Organic milk too. Pasta, once or twice. Pajamas, never.  So you may not be surprised to learn I read the new study linking ADHD to pesticides as my children gobbled up grapes that were not organic, this being New Jersey and not the West Coast where I imagine pesticide-free is an achievable if not cost-effect lifestyle.  After finishing the article published in the curre........

Experimental test of Darwin's naturalization hypothesis

by Marc Cadotte in The EEB and flow

Among the numerous and still informative ecological predictions made by Darwin, one posits that when species are introduced into regions where they were not formerly found, the most successful tend to not have close relatives already occupying the region. This is known as Darwin's Naturalization Hypothesis, and his logic was that among close relatives, where ecological requirements should be most similar, the struggle for existence is most severe. Thus the modern formulation is that invader succ........ Read more »

Humpback whales realize the importance of girl power!

by Dr. Carin Bondar in Dr. Carin Bondar - Biologist With a Twist

The bulk of research done on the evolution of sociality has focused on sexual pairings (aka interactions between males and females).  While such interactions directly affect the reproductive success of the individuals involved, they are certainly not the only kind of interaction that matters.  Female alliances have been shown to increase infant survival in a [...]...

Experimental virus treatment is still in development

by Cancer Research UK in Cancer Research UK - Science Update

Over the last week or so, we’ve received a lot of enquiries to our helpline and email service about a new experimental cancer drug called reolysin. This followed several reports in the national press the week previously. Reolysin is a relatively new drug developed from a fairly harmless type of virus called a reovirus. Most [...]... Read more »

While attending last year’s American Elasmobranch Society conference, I was asked to fill out a survey concerning my views on lethal shark research. My response, along with those of many other participants, has now been analyzed and written up into a new essay in the Journal of Conservation Biology. Michelle Heupel and Colin Simpendorfer argue [...]... Read more »

Autism, Psychosis and circadian clock

by sandygautam in The Mouse Trap











Image via Wikipedia



I recently came across this post by Michelle Dawson that states the thesis that one of the abnormalities in Autism spectrum disorders is due to abnormal circadian clock functioning. More specifically, the clock is internally driven and has a greeter ‘free running’ period and does not entrain readily to environmental and social clues.

SSRIs and Suicide

by Neuroskeptic in Neuroskeptic

Prozac and suicide: what's going on?Many people think that SSRI antidepressants do indeed cause suicide, and in recent years this idea has gained a huge amount of attention. My opinion is that, well, it's all rather complicated...At first glance, it seems as though it should be easy to discover the truth. SSRIs are some of the most studied drugs in the world. We have data from several hundred randomized placebo-controlled trials, totaling tens of thousands of patients. Let's just look and see wh........ Read more »

Niches of Sunlight

by Lab Rat in Lab Rat

In every environment there will be competition for resources, and there are generally two ways organisms deal with this; generalise or specialise. To generalise, you try to cope with as many different conditions as possible, so that if you get out-competed in one area you can try to cope with the conditions elsewhere. To specialise, you get damn good at using the conditions in your little niche, in the hope that you'll be better than anyone else who comes along, and be able to out-compete them.T........
