Molecular biologists bring gamers into the ‘fold’

Playing video games isn’t exactly rocket science but, thanks to a crowdsourcing computer game developed by University of Washington researchers, it can be molecular biology – and can offer hope to sufferers of tough-to-crack diseases such as Alzheimer’s, cancer and HIV.

Like John Henry versus the steam hammer or Garry Kasparov versus Deep Blue, Foldit players show that humans still have a thing or two to teach machines; unlike Henry, who died, or Kasparov, who lost in a rematch, protein-folding gamers still have an edge over the brute-force number crunching of supercomputers.

Fearful symmetry: the beauty and power of tessellations

We study mathematics for its beauty, its elegance and its capacity to codify the patterns woven into the fabric of the universe. Within its figures and formulas, the secular perceive order and the religious catch distant echoes of the language of creation. Mathematics achieves the sublime; sometimes, as with tessellations, it rises to art.

60 percent of the time, it works every time: the facts about pheromones

We hear a lot about pheromones these days. Scent sellers have been touting their powers of sexual attraction and libido amplification for years, but the science behind these claims is sketchy at best. Although pheromone production and detection by humans remains controversial, pheromones are used throughout the insect and vertebrate worlds, among crustaceans and even in plants, in exciting and often surprising ways.

What are pheromones?

Geneticists get the skinny on fat-control gene

A gene identified over 50 years ago in fruit flies could provide a valuable weapon in the battle of the bulge. The gene, which influences which fruit flies are svelte and which ones are zaftig, is found in humans as well. Whether it will one day lead to the mythical “skinny pill,” however, remains anyone’s guess.
