cold? what cold? it’s the uv rays that’ll kill you

by Greg Fish in weird things

It’s not that Mars is hostile to life as we know it, it’s just that even the toughest terrestrial microorganisms able to survive a big gamma ray burst from a nearby nuclear reactor die within ten minutes of exposure to a close simulation to the conditions on the red planet’s surface. That seems to be [...]... Read more »

In the News this month: emission from methane in the atmosphere of an extrasolar planet

by Megan in Rigel

In just fifteen years, have been discovered around stars other than the Sun using a variety of techniques. Even without the ability to directly image these other worlds, some of their properties can be determined. Most extra solar planets found so far are massive orbiting close to their parent stars, since these are the types of planets that the detection methods are most sensitive to. As develop and improve, astronomers are finding out more and more about these other worlds, including the co........ Read more »

In the News this month: the molecular content of early galaxies

by Megan in Rigel

A long-standing question in the study of is whether the process was more efficient in the early universe than it is today. Stars form through the collapse of clouds of cold gas. As the collapse progresses, the of the cloud gets denser and hotter until begins and a star is born. In the local universe, however, cold molecular gas is relatively rare so star formation occurs slowly; the Milky Way forms new stars at a rate of only a few per year. More distant galaxies formed stars at a much higher........ Read more »

In the News this month: the explosion mechanism behind type Ia supernovae

by Megan in Rigel

Supernova explosions are initially by the chemical signatures in their optical spectra. While some are caused by the catastrophic collapse of stars more than eight times as massive as the Sun, others are thought to be caused by , stars like the Sun which have already evolved off the main sequence and shrunk in size. Called Type Ia supernovae, such explosions are thought to have a fixed brightness, allowing them to be used as to measure distances to galaxies and test cosmological models of the ........

Bio-ontologies for everyone with new Microsoft Word Add-in

by Abhishek Tiwari in Fisheye Perspective

A latest paper in BMC Bioinformatics describes a Microsoft Word Add-in for ontology recognition. Tool is freely available from Codeplex portal and as prerequisite you will need Microsoft Word 2007. This add-in enables the annotation of scientific documents based on terms that appear in ontologies and controlled vocabularies. I am sure this tool is going to fuel the debate on the article of the future as like everyone else I think that the next generation of scientific articles will be semantic r........ Read more »

Science predicted the Chile’s Earthquake

by Pablo Astudillo in astu's science blog


I am finally back, repairing some of the damages in our labs. The situation in Chile is not good. The deaths are raising slowly, but continoulsy, over 800 people now. Also, some data regarding thousands of missing people is also of great concern.
Regarding to science, several laboratories have reported serious damages, including lost of data, [...]... Read more »

Comparing Child and Adult Brains: How to Account for Performance Differences?

by Livia in Reading and Word Recognition Research

In an ideal world, we’d be able to study maturational brain changes by scanning a group of adults, a group of children, and comparing the brain images. Unfortunately, there are complications.



One complication is that these studies usually require doing some kind of task in the scanner, and children usually have lower accuracy and longer reaction times on this task. These differences,

March Madness Preview: Neuroscience Edition

by Allison in Dormivigilia

This week in Neuro Journal Club, I discussed a recent Journal of Neuroscience publication finding high activation of attentional and premotor planning areas of the brain during the recall of basketball game plays in avid Duke and UNC fans. The Duke fans had faster recall vs. the UNC fans, despite no differences in activation intensity within these brain areas.

Porn is good for you

by Bryan in Imaging Geek

Science has some good news for any pornhounds that may be out there. Porn may be good for you.Its long been though that porn is associated with a range of negative social attitudes; including promoting sexual violence and negative attitudes towards women. Turns out that, at least in the case of these two issues, this doesn't appear to be the case.In a finding sure to piss off some feminists:Now let’s look at attitudes towards women. Studies of men who had seen X-rated movies found that they ........ Read more »

The ability to recognize faces is inherited

by Mo in Neurophilosophy

THE perception and recognition of faces is crucial for the social situations we encounter every day. From the moment we are born, we prefer looking at faces than at inanimate objects, because the brain is geared to perceive them, and has specialized mechanisms for doing so. Such is the importance of the face to everyday life, that we see faces everywhere, even when they are not there.We know that the ability to recognize faces varies among individuals. Some people are born with prosopagnosia, th........ Read more »

“Bird” Wrists Evolved Among Dinosaurs

by Brian Switek in Dinosaur Tracking

If there is one persistent gripe that paleontologists have with dinosaurs on screen, it is that their hands are usually wrong. From Tyrannosaurus to Velociraptor, predatory dinosaurs are time and again shown with their hands in a palms-down position, something that would have been anatomically impossible (at least without moving the arms to which those [...]...

Tip of the Week: Caleydo for gene expression and pathway visualization

by Mary in OpenHelix

Recently while watching the #bioinformatics tag on Twitter I saw Khader Shameer mention Caleydo.  I was instantly hooked at the very clever visualization strategy that they are using to provide more surface area for examining the data you are interested in viewing.  Their specific topics are pathways and gene expression, but it got me thinking about various data types that I would like to see connected in this way.
To skip right over to Caleydo and start trying it out, go here: http://www.cale........ Read more »
