Striking back at biological invaders
A special news section in the 17 September issue of Science highlights how scientists are fighting back against invasive species--exotic plants and animals that colonize and often wreak havoc on native ecosystems.

'Soapy' droplets make brighter clouds
Organic properties of some pollution particles can increase the number of cloud droplets, allowing more sunlight than normal to be reflected into space.

USGS Maryland office gears up for Floyd
As Hurricane Floyd heads for the Chesapeake Bay, teams of scientists are gearing up to do water-quality sampling and flood measurements.

USGS prepares for Hurricane Floyd in Massachusetts and Rhode Island
Hurricane Floyd is expected to bring significant amounts of rain to Mass. and Rhode Island on Thursday and Friday.

HHMI researchers and their colleagues are making fundamental advances in understanding how genes control the shape and spatial orientation of organs.

New study confirms importance of systolic blood pressure
New evidence from the National Heart, Lung, and Blood Institute's Framingham Heart Study finds that systolic blood pressure, far more than diastolic blood pressure, identifies patients with hypertension, determines their blood pressure stage, and indicates the need for treatment, but both measurements used together are best.

Male courtship pheromone identified
University researchers have discovered one of the first pheromones in a vertebrate animal species that is produced by the male and helps him when courting a female, in this case making her more calm, receptive to mating and less apt to run away.

UF researchers screen newborns for genetic susceptibility to diabetes in effort to find causes and cures
Scientists do not know which of many suggested culprits, including viruses, diet and other environmental factors, are responsible for diabetes.

Bubonic plague kills by cutting off cellular communication
Yersinia pestis, the deadly bacterium that causes bubonic plague, kills by cutting off a cell's ability to communicate with other immune system cells needed to fight off the bacterial invasion.

Even hurricanes have silver linings
Hurricanes may not be all bad, despite the destruction caused by storms like Floyd.

Study tests vitamins in recovery from trauma

Making industrial isotopes cheaper and with less pollution
Gaseous diffusion, a dirty, expensive process which provides relatively pure forms of elements for microelectronics, medical tracers and nuclear fuel, may have met its match.

Future uses of MicroElectricalMechanical (MEM) systems to be featured at Santa Clara show
