A new research shows us how silkworms beat materials scientists by spinning silk with minimum energy expenditure. Scientists demonstrate that natural silks are a thousand times more efficient than synthetic polymers when it comes to forming fibers. 

Embryonic stem cell therapy took a wild twist last week, when one of the first and strongest players withdrew from an ongoing embryonic stem cell-based clinical trial.  After years of aggressive research and development in embryonic stem cell technology and treatment strategies, and initiating a clinical trial for spinal cord injury with fanfare, Geron, a Menlo Park, California company, de

Scientists have now provided new insight into how our brain perceives shades of gray. We are able to see in the starlight or in the bright sun, though the difference in illumination may be in multi-million folds.  The new research report explains how our brains deliver a perception of objects that is stable over this huge range of light that gets to our eyes.

Researchers have detected contrasting patterns of drug resistance in malaria-causing parasites taken from both humans and mosquitoes in rural Zambia. Parasites found in human blood samples showed a high prevalence for pyrimethamine-resistance, which was consistent with the class of drugs widely used to treat malaria in the region.

Researchers now reveal the creative power of Foldit players' strategies and compare them to the best-known scientist-developed methods. This report follows a recent paper on solving the crystal structure of a monomeric retroviral protease by protein folding game players.
