Richter DC, Ott F, Auch AF, Schmid R, & Huson DH (2008). MetaSim: a sequencing simulator for genomics and metagenomics. PloS one, 3 (10) PMID: 18841204An article from the Huson's Group at Tübingen University has just came out in the Open Access (and scientific publishing innovator) journal PLoS ONE, describing MetaSim, a software to produce artificial or syntetic or in silico metagenomes out of a selection of completely sequenced genomes.This is just "heaven-sent" for me since I've been wor........

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........

Relativity on a Human Scale

by Chad Orzel in Uncertain Principles

While I mostly restricted myself to watching invited talks at DAMOP last week, I did check out a few ten-minute talks, one of which ended up being just about the coolest thing I saw at the meeting. Specifically, the Friday afternoon talk on observing relativity with atomic clocks by Chin-Wen Chou of the Time and Frequency Division at NIST in Boulder.

The real technical advance is in a recent paper in Physical Review Letters (available for free via the Time and Frequency Publications Database, b........ Read more »

Is air pollution responsible for rising rates of diabetes?

by Yoni Freedhoff in Weighty Matters

A recent study says so.The study, Traffic-related Air Pollution and Incident Type 2 Diabetes: Results from the SALIA Cohort Study set out to look at 1,775 non-diabetic middle aged women and their incidence of developing type 2 diabetes over a 16 year period as a function of their exposure to traffic-related air pollution. The study was conducted in Germany and the authors hypothesized that particulate matter air pollution may promote the development of type 2 diabetes with the proposed mechanism........ Read more »

When what an acupuncture study shows is much more interesting than what acupuncture believers think it shows

by Orac in Respectful Insolence

Of all the "alternative" therapies out there, arguably the most studied is the modality known as acupuncture. Perhaps the reason is that, unlike homeopathy, which based on physics, chemistry, and biology alone is so implausible that, for it to "work," huge swaths of well-established physics and chemistry would have to be shown to be not just wrong but extravagantly and outrageously wrong (making homeopathy far more akin to magic than science), or reiki, which, when you come right down to it, is ........
