Balaur bondoc: A Raptor Unlike Any You Have Ever Seen

by Brian Switek in Dinosaur Tracking

Thanks to their prominent appearances in museum displays and the Jurassic Park film franchise, many people are very familiar with what dromaeosaurid dinosaurs looked like. Relatively small and lightly-built, these predators had long, grasping hands and a hyperextendable second toe on each foot tipped in a large sickle-shaped claw. But a newly-discovered “raptor” from the [...]... Read more »

Originally posted on Cognitive Daily. This is a guest post by Aaron Couch, one of Greta’s top student writers for Spring 2007 When looking out a window, or watching a movie in a theater, the image you see is typically presented as right-side-up.

The Price of Sequencing Versus the Cost

by Mike in Mike the Mad Biologist

So, Nature Reviews Genetics has an article, "Computational solutions to large-scale data management and analysis", which claims the following in the abstract (italics mine):

Today we can generate hundreds of gigabases of DNA and RNA sequencing data in a week for less than US$5,000. The astonishing rate of data generation by these low-cost, high-throughput technologies in genomics is being matched by that of other technologies, such as real-time imaging and mass spectrometry-based flow cytomet........

Rapid Human Adaptation to High Altitudes

by Daniel Koboldt in Massgenomics

Two studies in the journal Science demonstrated that genes in the hypoxia-inducible factor (HIF) oxygen signaling pathway have undergone strong, recent positive selection in Tibetan highlanders. One study was a genome-wide scan using SNP arrays; the other a large-scale exome sequencing effort. The exome study was particularly interesting; using the Nimblegen 2.1M exon capture array [...]...

Kidney Fat Predicts Kidney Disease?

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

Yesterday, at the ongoing 2010 European Society of Cardiology, I attended as session focussing on the potential role of excess fat tissue that may surround blood vessels or the heart. Regular readers will recall, that the role of these fat depots have been a focus of my interest in past years.

A Reflection on the Mirror Box

I met a fellow called Max. He was impressive with his command of the facts.  He does some cool studies.  He’s not one of the Luddies.  And certainly not one of the hacks.  That is what happens when one is a bit too low on sleep.  Which I am. But Max is not. Max works [...]... Read more »

Neurons in the wild

by Zen Faulkes in NeuroDojo

Anyone who’s thought about science knows the promise and perils of simplification. People joke about physicists who begin working on an applied problem by saying, “Assume the cow is a perfect sphere...”

Working on an animal in a lab is a little like assuming a cow is a perfect sphere. You can get a pretty long way by simplifying the situation. But as I’ve talked about before, you often get many unexpected and delightful findings when you let an animal be an animal, in the environment an........ Read more »

Solar cells brought into shape

by Joerg Heber in All That Matters

Solar energy is a huge market and any improvement to the efficiency of solar cells has a significant impact. In 2008, worldwide photovoltaic solar energy production was about 5 gigawatts, and this is expected to rise to 15 gigawatts in 2015. To put this figure in context, a nuclear reactor produces around 1 to 1.5 [...]... Read more »

Chemistry of the Great Big Blue: Metals

by Bluegrass Blue Crab in Southern Fried Science

The ocean is full of metals and minerals that naturally occur such as zinc, copper, and cobalt and many marine organisms therefore depend upon access to those metals in small concentrations. However, inshore marine systems receive inputs from industrial, mining, and stormwater runoff that far exceed what these organisms can use. So what’s the effect?  [...]... Read more »

How good are we at estimating other people's drunkenness?

by BPS Research Digest in BPS Research Digest

Sloshed, trollied, hammered, plastered. We've done a sterling job of inventing words for the inebriated state, but when it comes to judging from their behaviour how much a person has drunk, we could do (a lot) better. That's according to a review of the literature by US psychologist Steve Rubenzer.

We all have our trusted indices for judging other people's drunkenness. Perhaps it's when the eyeballs start floating about as if under the control of a clumsy puppeteer. Or maybe the effusive 'you k........ Read more »

Someone finally dissects the role new neurons play in fear conditioning

by Jason Snyder in Functional Neurogenesis

Based on a true story – how progress is made in the field of adult neurogenesis*

A group of scientists reduce neurogenesis and report a memory deficit.
A second group repeats the experiment, with only a few minor differences in protocol, and fails to find a memory deficit.
A third group, using the same species as the first [...]... Read more »
