Mapping the Militant-Extremist Mindset

by Randy Borum in Science of Global Security & Armed Conflict

About a year ago, we reported here at SGSAC on a study attempting to identify key themes that might characterize a militant-extremist mindset. Gerard Saucier (University of Oregon) and his colleagues pored through numerous documents and extracted sixteen themes. Members of that same research team - this time led by Lazar Stankov (National Institute of Education in Singapore) - have continued this line of inquiry and spotted three central "psychological ingredients of the militant extremist min........

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 »

Looking Deeper: Can Exercising 10 Minutes A Day Be Better Than 10 Hours?

by Christie Wilcox in Nutrition Wonderland

A recent paper in The Journal of Physiology titled, "A practical model of low-volume high-intensity interval training induces mitochondrial biogenesis in human skeletal muscle: potential mechanisms." has caused quite a stir. It centers around a recent fashion in workouts called High-Intensity Interval Training, or HIT. HIT is a method of exercise which involves working as hard as you can for brief intervals followed by brief rest intervals. The idea is that by doing higher intensity workouts fo........ Read more »

Many people get a little melancholy as the winter months take away sunshine and warm weather. But, for some, the winter blues become a serious case of depression. Recent lawsuits have designated this recurrent seasonal depression, or seasonal affective disorder (SAD), as a disability that requires accommodation by employers. However, these rulings are provoking renewed [...]... 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 »

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 »

Milgram's personal archive reveals how he created the 'strongest obedience situation'

by BPS Research Digest in BPS Research Digest

Stanley Milgram's 1960s obedience to authority experiments, in which a majority of participants applied an apparently fatal electric shock to an innocent 'learner', are probably the most famous in psychology, and their findings still appall and intrigue to this day. Now, in a hunt for fresh clues as to why ordinary people were so ready to harm another, Nestar Russell, at Victoria University of Wellington, has reviewed Milgram's personal notes and project applications, which are housed at Yale Un........

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:

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

.......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 »

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:
