New theory of how animals smell

In the real world, odors don't happen one puff at a time. Animals move through, and subsequently distort, plumes of odor molecules that constantly drift, changing direction as the wind disperses them.

Electrical stimulation of the brain offers hope for Parkinson's sufferers

Electrical stimulation of the brain -- a treatment in which a pacemaker-like device sends pulses to electrodes implanted in the brain -- is riskier than drug therapy but may hold significant benefits for those with Parkinson's disease who no longer respond well to medication alone.

Light exposure therapy, dark sunglasses help night-shift workers

A new study finds the use of light exposure therapy, dark sunglasses and a strict sleep schedule can help night-shift workers create a "compromise circadian phase position," which may result in increased performance and alertness during night shifts while still allowing adequate nighttime sleep on days off.

Ultrafast photodynamics of DNA

DNA, the molecule that acts as the carrier of genetic information in all forms of life, is highly resistant against alteration by ultraviolet light, but understanding the mechanism for its photostability presents some puzzling problems. A key aspect is the interaction between the four chemical bases that make up the DNA molecule.
