Computers close in on protein structure prediction

...s. Some amino acids tend to dive toward the watery world of the protein surface while others take cover inside the protein. The computer also accounts for the social habits of the 20 amino acids; some want to be close to each other and others like their distance. In stage two, Rosetta replaces the fuzzy p...

Retina adapts to seek the unexpected, ignore the commonplace

... of Arts and Sciences. "Our eyes report the visual world to the brain, but not very faithfully. Instead, the retina creates a cartoonist's sketch of the visual scene, highlighting key features while suppressing the less interesting regions." These findings provide evidence that the ultimate goal of the vi...

Leber congenital amaurosis is an inherited disease that is believed to cause up to 20 percent of all cases of childhood blindness. It is caused by mutations in several different genes inclu...

Acid water in East Java threatens biodiversity and local welfare

...is the largest collection of volcanic water in the world and is extremely acidic (pH 0.1). The acidic water slowly seeps away, and despite dilution by two tributaries in the area the pH of the river water remains very low. This water is used for agricultural and household purposes, which sometimes leads to...
