The Social Brain and the Human Condition

by Robert Deyes in Promega Connections

The plans had been made, details finalized and all expenses paid. I was to travel to the south coast of England to complete my training for the British Sub-Aqua Club Sports Diver certificate. I boarded a train from London’s Waterloo station down to the quiet seaside resort of Bournemouth where I was received [...]... Read more »

The many lives of an inverted genomic region

by Razib Khan in Gene Expression

About five years ago Kari Stefansson published an interesting paper, A common inversion under selection in Europeans. The basic thrust of the results was that a particular genomic region in Europeans exhibited a pattern of variation whereby there was one variant which was inverted in relation to the modal type. They labelled them “H2″ and [...]... Read more »

Monday Pets: The Gambler

by Jason Goldman in The Thoughtful Animal

So I’m in Las Vegas, gambling capital of the world. And I was reminded of the Kenny Rogers song, The Gambler. And of this video of Kenny Rogers singing The Gambler with the muppets. Because the muppets make everything better.

fusing biology and computer science?

by Greg Fish in weird things

When two of the leading experts in genomics published their thoughts about the future of genetics in Nature’s retrospective on the Human Genome Project, one of them didn’t devote significant parts of his editorial to a simple laundry list of goals and challenges in his field. Instead, J. Craig Venter called on a seemingly unlikely [...]... Read more »

Six Hours Per Day

by Reason in Fight Aging!

An article from the Duke University media outlet reminds us of the bigger historical picture of human life expectancy: continual incremental improvement ever since the Industrial Revolution. It's also a good example of how to write a decent popular science press piece, one that adds context to the research it references, rather than dumbing it down or papering it over. From the perspective of the reliability theory of aging and longevity, the historical increase in life expectancy has occurred b........ Read more »

Protecting the elusive, cave-dwelling troglobites

by Katie Kline in EcoTone

“Who will speak for the imperiled troglobites? Charismatic megafauna, they are not. Troglobites—not to be confused with troglodytes (cavemen) or trilobites (extinct arthropods)—are neither warm-blooded nor fuzzy. Most are invertebrates, including insects and crustaceans, but there are also troglobitic fish and amphibians—and all are as weird as they are rare.”... Read more »

Will virtual screening ever work?

by The Curious Wavefunction in The Curious Wavefunction

Virtual screening (VS), wherein a large number of compounds are screened, either by docking against a protein target of interest or by similarity searching against a known active, is one of the most popular computational techniques in drug discovery. The goal of VS is to complement high-throughput screening (HTS) and the ideal goal is to at least partly substitute HTS in finding new hits.But this goal is still far from being achieved. VS still has to make a significant contribution in the discov........ Read more »

Why We Sequence Cancer Genomes

by Daniel Koboldt in Massgenomics

A recent article on GenomeWeb profiling the XGen Congress meeting in San Diego, where researchers debated the question of whether sequencing cancer genomes has clinical relevance. In a roundtable discussion, University of Washington’s Larry Loeb argued that cancer is too heterogeneous for sequencing to uncover the therapeutically-relevant mutations. As an example, he pointed to AML1 [...]... Read more »

Margays mimick monkey calls to lure their prey

by Laelaps in Laelaps



A margay (Leopardus wiedii). From Wikipedia.




Even if they spend years in the field, researchers rarely witness predation on primates. Cats, birds, and other hunters regularly feed on primate species, but what we know about the habits of primate-hunters often comes from bones and fingernails picked out of predator droppings. Every now and again, though, someone is in just the right place at just the right time to observe a predator attempt to catch a primate for dinner, and one recent obser........ Read more »

A New Ant-Eating Dinosaur, Xixianykus

by Brian Switek in Dinosaur Tracking

Paleontologist David Hone has been on a hot streak lately. Earlier this month he and his colleagues described the new predatory dinosaur Linheraptor, and just last week he was part of another team of researchers who described another new dinosaur, Xixianykus zhangi.
As presented in the journal Zootaxa, Xixianykus was an alvarezsaurid. This was a bizarre [...]... Read more »

The diversity of teff

by Jeremy in The Vaviblog

Despite endless efforts by development agencies to get Ethiopians to grow grains other than teff, roughly fifty million Ethiopians still use enjera as their daily bread, consuming close to 1.6 million metric tons of teff flour a year.
Just as no two displays of vegetables and sauces on enjera are alike, no two teff fields are [...]... Read more »

Friday Weird Science: Coke Bees.

by Evil Monkey in Neurotopia

Sci was going to try and stick with the sex this week, but this paper reminded her SO much of this article in the New Yorker, which then reminded her SO much of that awesome YouTube video, and the next thing you knew Sci had to blog bees on crack. It's how I roll.

But first, let's get in the mood:


(Nice web, crack spider)

Eating high fructose corn syrup makes Yogi bear.......

by Sunil in Balancing life

.......fatter than the average bear.Apologies for that awful title that I couldn't resist.If you are fond of sweets, chocolates, candy, cookies and ice cream, and have ever read the label for the ingredients, you must have noticed one of them, called high fructose corn syrup (HFCS). You might have wondered about it a little, or just thought that fructose is sweet like glucose, and gone on with your indulgence. HFCS has now largely replaced table sugar (or sucrose) as the main sweetener in most........ Read more »

Cold Blooded Cognition

by Jason Goldman in The Thoughtful Animal

She: “What are you writing about?”
Me: “Cognition in cold-blooded animals.”
She: “Hot.”
Most people who study cognition focus on mammals or birds. But I hope I’ve convinced you that other animals are important to investigate as well. One research group at the University of Vienna likes cold-blooded critters. Turtles and lizards and such. They argue:
Reptiles, birds and [...]... Read more »
