Virtual Therapy – Wave of the Future?

by Shaheen Lakhan in Brain Blogger

Depression is a mood disorder characterized by the absence of a positive effect, low mood, and various associated emotional, physical, cognitive, and behavioral symptoms. Associated symptoms include sadness, pessimism, loss of interest, changes in sleep, decreased appetite, and decreased motivation. New technology has allowed depression to now be treated by way of computer. European countries [...]... Read more »

The Cretaceous birds and pterosaurs of Cornet: part II, the pterosaurs

by Darren Naish in Tetrapod Zoology

It's always been clear that pterosaurs were present in the Cornet assemblage (for the background on Cornet and its archosaur fossils, you need to have read part I).

However, exactly what sort of pterosaurs are present at Cornet has been somewhat uncertain: the Late Jurassic ctenochasmatoid Cycnorhamphus, ornithocheirids and the Early Cretaceous Asian dsungaripterid Dsungaripterus were all reported from the assemblage during the 1980s (e.g., Jurcsák & Popa 1984) but, as with the birds, the........

Researchers discover genetic ‘volume control’ for inherited breast cancers

by Cancer Research UK in Cancer Research UK - Science Update

Back in the 1990s, Cancer Research UK scientists played a fundamental role in the discovery of two major “cancer genes”, BRCA1 and BRCA2. Inheriting a fault in one of these genes greatly increases a woman’s risk of breast cancer, and they’re also linked to an increased risk of prostate and ovarian cancer. Thankfully, inherited faults [...]... Read more »

Transfer of transgenic crop toxins to aquatic ecosystems potentially widespread in the industrial Corn Belt of the U.S.

by Phil Camill in Global Change: Intersection of Nature and Culture

Genetically modified organisms (GMOs) are back in the news.  A few days ago, NPR featured a couple of blog posts (here and here) considering whether the new GMO “supersized” salmon will be harmful to aquatic ecosystems.
A concern with GMOs is that—like the early adoption of pesticides—potential risks are being borne by the environment and consumers [...]... Read more »

The title of this posting refers to the excellent article from David Dobbs I bookmarked very recently. I’d like to present you a very interesting initiative from French bioscience research program for high-school students called « Tous chercheurs ». The Community Page of the very last PLoS Biology is dedicated to this project and I find it really great. Because, indeed, publishing your science paper is only half of the job.... Read more »

Choosing an algorithm – benchmarking bioinformatics

by Grant Jacobs in Code for life

You’ve been asked to to run a bioinformatics analysis. How do you choose what algorithm to use?

My first suggestion would be to talk to experienced bioinformatics scientists or computational biologists. It’s a lot quicker, and it’ll save you making mistakes that the research literature assumes you know better not to. You’ll also avoid the trap [...]... Read more »

American family values: where even the dull can dream!

One of the issues when talking about the effect of environment and genes on behavioral and social outcomes is that the entanglements are so complicated. People of various political and ideological commitments tend to see the complications as problems for the other side, and yet are often supremely confident of the likely efficacy of their [...]...

Faculty, librarians and student research skills: are we on parallel paths?

One of the themes I’ve been writing a lot lately is that department faculty and librarians aren’t talking to each other as much as they should, especially in areas that they are both concerned about.  One of the biggest areas we need to be talking more about concerns student’s library research skills (or information literacy [...]...

Was Ice the Original "Cell" in Early Earth?

The research of Philipp Holliger (Medical Research Council, United Kingdom) and coworkers suggests that ice may have helped the first RNA molecules to self-replicate and isolate themselves from the surrounding environment, thereby serving as the first primitive living "cell."

Fear/Anxiety/Avoidance – treatments review!

For years, clinicians working in pain management have mixed together a rich assortment of strategies to help people function better.  But to identify the ‘active ingredients’ of multidisciplinary pain management using a cognitive behavioural approach, it’s been important to tease each element apart.  One size does not fit all – and just as a physician … Read more...

How to burn a few extra calories while at work

by Peter Janiszewski, Ph.D. in Obesity Panacea

On a number of occasions Travis has pointed to the negative health effects of sedentary activity, such as sitting, for extended periods of time. That is, regardless of the amount of exercise you get, the more time you spend sitting (an inevitable consequence of office work for many of us) the higher your risk of disease. Thus, we should be trying our best to limit the amount of time we spend sitting.
Some people are proponents of things like the treadmill desk. Some prefer sitting on an exercise........ Read more »

Commuting to Work

by Moselio Schaechter in Small Things Considered

by Elio

An underwater microbial mat has been found in fairly shallow waters off the coast of Chile and, according to headlines (click here and here), it’s the size of Greece, or about 132,000 km2 (or for us norte-americanos, about the size of Alabama). These communities of sulfide-oxidizing bacteria have been known for some time, but their attention has been highlighted by the recent version of the Census of Marine Life. In fact, they were discovered in 1963 by the oceanographer and microbiol........ Read more »

Pleiades Promoter Project

A recent paper in PNAS describes the development of MiniPromoters: human DNA promoters of less than 4 kb, designed to drive gene expression in specific areas of the brain. The initiative is called the Pleiades Promoter Project, and so far they have confirmed brain-region specific activity in knockin mice for 27 of their MiniPromoters. The [...]... Read more »

Distinguishing Our Universe From Other Similar Universes In The Multiverse.

by Joseph Smidt in The Eternal Universe

Srednicki and Hartle have raised an interesting concern recently about a limitation on the predictive power of multiverse theories. They observe that in multiverse theories, exact snapshots of our universe happen several times in different places. So if we want to have a physical theory that describes our universe, the one we live in, then the question arises: how can we tell which one it is from
