Butterflies are flashers to attract mates
Researchers have discovered that some iridescent butterflies use the polarization of light refracted from their intricate prismatic scales as a mating signal -- the first time that light polarization has been identified as a mating signal for any terrestrial animal species.

New approaches to prenatal ultrasound can predict high-risk births with greater accuracy
The risk of newborn death or disability is highest for the smallest babies, so doctors continually seek better interventions and more precise diagnostic tools to identify and protect the most vulnerable.

Anthrax genome decoded
The complete genetic blueprint of Bacillus anthracis--the microbe that gained notoriety during the 2001 anthrax mail attacks--is now known, researchers announced today.

Researchers discover structure of Nature's 'circuit breaker'
Howard Hughes Medical Institute researchers have answered an important question in biology by discovering the exquisite mechanism by which channels in the cell membrane sense voltage changes that trigger them to snap open or slam shut with extraordinary speed and precision.

UT Southwestern researchers, Nobel Prize winners share 2003 Albany Medical Center Prize
Dr. Michael S. Brown and Dr. Joseph L.

The price of prejudice: Interactions with minorities can sap mental capacity
People with racially prejudiced attitudes may suffer a previously unrecognized cost for their outlook: temporary impairment of some forms of mental functioning.

MacKinnon lab's newest picture tells action potential story
Scientists studying the tiny devices -- called voltage-dependent ion channels -- that are responsible for all nerve and muscle signals in living organisms for 50 years have been working like a bunch of blindfolded art critics.Rockefeller University's Roderick MacKinnon, M.D., a Howard Hughes Medical Institute Investigator, Youxing Jiang, Ph.D., and their colleagues have removed the blindfold to reveal a masterpiece of nature's engineering.

Senators' approval ratings influenced largely by factors beyond control
Senators' own attempts to influence approval ratings have less effect than factors beyond their control, according to a new study.

Borrowing from Ebola virus could aid cystic fibrosis gene therapy
A problem with current efforts in developing a cystic fibrosis gene therapy is that delivering genes into airway cells is inefficient and requires disrupting the integrity of the cell layer.

Researchers find new piece of cell growth puzzle
In biology, size matters. Cell growth, the process whereby cells increase in mass, is critical to many life functions and has been implicated in diseases such as cancer and diabetes.

Test blunders risk needless abortions
Pregnant women in the US are having risky and unnecessary fetal tests following misinterpretation and confusion over genetic screening carried out on them and their partners.
