A puzzle that has baffled scientists for centuries -- why some birds appear to be male on one side of the body and female on the other -- has been solved by researchers. The research, which involved studying rare naturally occurring chickens with white (male) plumage on one side and brown (female) plumage on the other, sheds new light on the sexual development of birds.

Smell of salt air surprisingly detected a mile high and 900 miles inland

In a surprise with implications for air quality, researchers have found that chemistry involving airborne chloride, thought to be restricted to sea spray, occurs at similar rates in air above Boulder, Colo., nearly 900 miles away from any ocean.

First direct evidence of neuroplastic changes following brainwave training

Significant changes in brain plasticity have been observed following alpha brainwave training. Researchers have discovered the first evidence of neuroplastic changes occurring directly after natural brainwave training. They have demonstrated that half an hour of voluntary control of brain rhythms is sufficient to induce a lasting shift in cortical excitability and intracortical function.

Temporary hearing deprivation can lead to 'lazy ear'

Scientists have gained new insight into why a relatively short-term hearing deprivation during childhood may lead to persistent hearing deficits, long after hearing is restored to normal. The research reveals that, much like the visual cortex, development of the auditory cortex is quite vulnerable if it does not receive appropriate stimulation at just the right time.

Physicians click their way to better prescriptions

Is it time for all community-based doctors to turn to e-prescribing to cut down on the number of medication errors? Electronic prescriptions can dramatically reduce prescribing errors -- up to seven-fold, according to a new study of the benefits of e-prescribing in primary care practices.

Neutropenia: Research findings expected to ease treatment of low neutrophil counts in cancer patients

New research may change neutropenia treatment for all childhood cancer patients. Neutropenia is the dangerous drop in white blood cells that leaves cancer patients at increased risk for infections and can delay chemotherapy.
