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 »
Self-proclaimed insomniacs should be asking themselves right now if they've got either a "softcore" or a "hardcore" sleep problem on their hands. What's the difference between softcore and hardcore insomnia and why is it important you ask? First, let's define the terms. Softcore insomnia = complaint of insomnia with normal sleep duration greater than or equal to 6 hours of sleepHardcore insomnia = complaint of insomnia with less than or equal to 6 hours of sleepFernandez-Mendoza and colleagues f........

Mike Smith has an interesting post about the scale of monumental architecture, focusing on the fact that the Templo Mayor in the Aztec capital Tenochtitlan, one of the best-known archaeological sites in Mesoamerica, would fit comfortably as one of several similarly sized elements on the enormous platform at the heart of Tzintzuntzan, the capital of [...]...

I suppose I’ve been around the world of exercise science for long enough to see plenty of fads come and go. For God’s sake, I just heard about a “cookie diet” while driving home from work today. I’ve oft lamented that the conditioning and rehabilitation communities are sometimes a bit quick to embrace fads. While I’m [...]... Read more »

As today is Good Friday, perhaps it's a good time to talk about death in the digital world. While millions of Catholics engage in rituals of remembering today, I'd like to talk about how Web 2.0 technologies are changing the experience of death for those charged with remembering.
Death has been referred to as the great equalizer—it is the one fate we cannot escape. And cultures around the world

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 »
A supply chain is never stronger than its weakest link. Rigid supply chains are particularly weak, unlike flexible supply chains that can bend and adapt to new situations. Flexible supply chains can indeed “flex” their supply chain management muscles (pun intended) and show the strength that lies in them. With transportation being a key ingredient [ ... ]...

Haskins Laboratories - brain areas activated during reading.An unfocused and rambling article in the New York Times the other day was excited about the potential use of neuroimaging to revive the gloomy state of university literature departments.

“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 »

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.

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.

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 »
