Students’ writing procrastination – not anymore!
by Anatoliy Gruzd in Social Media Lab
Even under the best of circumstances, the process of writing can be challenging for both professional and novice writers alike. For novice writers such as university students, the difficulties associated with writing can be further exacerbated when it is combined with their tendency to procrastinate and delay starting a paper till the night before it is due. Unfortunately, it seems that regardless of what an instructor may say or do, many students still inevitably get caught in an endless loop o........ Read more »

The 3rd OBO Foundry Workshop 2010, Cambridge, UK
by Duncan Hull in O'Really?
The Open Biomedical Ontologies (OBO) [1] are a set of reference ontologies for describing all kinds of biomedical data shared in a centralised OBO Foundry. Every year, users and developers of these ontologies gather from around the globe for a workshop at the EBI near Cambridge, UK. Following on from the first workshop two years [...]... Read more »

There’s a tweeting emergency
by David Bradley in Sciencetext
If you join Twitter in response to a major emergency situation, you’re more likely to become a long-term adopter of the technology. Many early users shared nothing more than the minutiae of their everyday lives on the personal micro-blogging service. However, the Mumbai Taj Hotel terrorist attack, the Hudson River plane crash, California wildfires, Australian [...]Post from: David Bradley's Sciencetext Tech TalkThere’s a tweeting emergency

Nature-inspired network design: recent studies in slime mold and leaf veins
by Hannah Waters in Culturing Science – biology as relevant to us earthly beings
Nature-inspired design: this phrase makes me think of shark-skin swimsuits, velcro, and an endless assortment of coffee tables using natural knots and tree branches. There is logic behind design reliant upon natural elements. After all, organisms have been undergoing evolution for millions of years for the sake of efficiency. If anyone knows how to [...]...

Classic paper: Montagues and Capulets in Science
by Duncan Hull in O'Really?
In preparation for a joint seminar I’ll be doing with Midori Harris here at the EBI, here’s a classic paper [1,2] on the social problems of building biomedical ontologies. This paper is worth reading (or re-reading) because it makes lots of relevant points about the use and abuse of research and how people misunderstand each [...]... Read more »

10 Websites With The Best Information on Depression
by Dr Shock in Dr Shock MD PhD
After searching for websites about depression (‘‘depression,’’ ‘‘depression treatment,’’ and ‘‘depression help’’) with a popular search engine: Google, the authors of this work carefully examined the websites. The websites were evaluated on accountability, interactivity, esthetics, readability and content quality. They also used the brief DISCERN as a content quality indicator for general consumers. They found [...]

VarScan 2 Released on SourceForge
by Daniel Koboldt in Massgenomics
Accurate variant detection in massively parallel sequencing data is a significant bioinformatics challenge. Not only do new sequencers offer unprecedented breadth (whole genome) and depth (30x or more), but they suffer coverage biases and error rates that make variant calling difficult. Last year, we published VarScan, our in-house algorithm for SNP and indel detection on [...]... Read more »

Forty years of hackers at the movies
by David Bradley in Sciencetext
There are two definitions of “hacker” the first is the one we geeks mean when we call someone a hacker – a person skilled in using technology, particularly computers, who enjoys understanding the inner workings of that technology, perhaps for personal education.

Story behind the science: #PLoS Genetics "Evolutionary mirages" paper
by Jonathan Eisen in The Tree of Life
So there is this cool new paper out in PLoS Genetics: Evolutionary Mirages: Selection on Binding Site Composition Creates the Illusion of Conserved Grammars in Drosophila Enhancers. and I have wanted to write about it for a week or so. You see, the paper is about something I have been interested in for most of my career - how the particular processes by which mutations occur can sometimes be biased (i.e., some types of mutations are more common than others) and that these biases can create high........

Evolving Robots
by Bryan in Imaging Geek
Creationists often like to claim that complex traits cannot arise from the "simple" processes of mutation and selection. They often claim that these processed are not even observable (even though we've been observing them since we began breeding plants and animals).
Anyone with even a basic grasp of science knows the above claims are pure BS, but not being content with simply being right, some scientists have now gone the extra mile and used evolution to make ROBOTS.
And ........ Read more »

Finding Recurrent CNVs in Cancer
by Daniel Koboldt in Massgenomics
Copy number aberrations (CNAs) represent one of the most prevalent genetic alterations in cancer cells. There is considerable interest in finding CNAs that affect the same chromosomal region in multiple tumor samples. Recurrent CNA (RCNA) implies the presence of key cancer genes; on chromosome 7, for example, we often see amplification of the region containing [...]... Read more »
