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 »

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........

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 [...]...

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 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 »

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 »

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 »
