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........

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 »

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 »

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.

However, these rulings are provoking renewed [...]... Read more »

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 »

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.
