New JILA apparatus measures fast nanoscale motions
A new nanoscale apparatus developed at JILA offers the potential for a 500-fold increase in the speed of scanning tunneling microscopes, perhaps paving the way for scientists to watch atoms vibrate in high definition in real time.

Research has shed light on the computer frustrations that plague older adults
A number of evolving social changes highlight the importance of making computer technology accessible and usable for older adults.

Black-white life expectancy gap narrows, but remains substantial
Reductions in the death rate from homicide, HIV disease, unintentional injuries -- and among women, heart disease -- have contributed to narrowing the life expectancy gap between blacks and whites in the United States, although substantial inequalities and challenges remain, according to a study in the March 21 issue of JAMA.

1-nanometer resolution is NSF CAREER researcher's goal for optical imaging
In the field of nanotechnology, researchers are discovering ways to arrange atoms into unique structures on the molecular scale.

Racial disparities seen in male breast cancer survival
A new study shows that among men treated for breast cancer, African-American men are more likely to die of the disease compared with white men.

Neighbors gone, fruits gone, species gone
Trochetia blackburniana, a rare Mauritian plant, with large red flowers, depends on its pollinator, the day gecko, whose favorite hideout is the maze of spiky leaves offered by dense patches of Pandanus plants.

38 minority scientists receive travel fellowships to Experimental Biology 2007 in D.C.

New reference material for diagnosing kidney disease
NIST has developed a new Standard Reference Material to help improve the accuracy of clinical diagnostic tests for chronic kidney disease.

Why are male antlers and horns so large?
Since Darwin, researchers have supposed that the large size of male ungulate antlers and horns is a signal that this is a male with sexual vigor, health, strength, hierarchical status or the ability to fight.

Robotic telescope unravels mystery of cosmic blasts
Scientists have used the world's largest robotic telescope to make the earliest-ever measurement of the optical polarisation of a Gamma Ray Burst (GRB) just 203 seconds after the start of the cosmic explosion.

Some caterpillers just don't want to grow up
An international project explores why it's an evolutionary advantage that only 25 percent of the caterpillars of Maculinea rebeli, a Lycaenid butterfly whose caterpillars live as parasites inside colonies of Myrmica ants, feeding on regurgitations from the nurse ants, complete development within one year.

$7.9M awarded to UCI stem cell scientists
UC Irvine scientists today were awarded $7.9 million in the second round of stem cell research funding from the California Institute for Regenerative Medicine.

Trojan horse strategy defeats drug-resistant bacteria
A new antimicrobial approach can kill bacteria in laboratory experiments and eliminate life-threatening infections in mice by interfering with a key bacterial nutrient, according to research led by a University of Washington scientist.

Crops feeling the heat
Warming temperatures since 1981 have caused annual losses of roughly $5 billion for the major cereal crops, a study has found.

Procedure predicts embryos most likely to result in pregnancy
To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF.

World first in medical robotics
Some 40 years after the release of the classic science fiction movie Fantastic Voyage, researchers in the NanoRobotics Laboratory of École Polytechnique de Montréal's Department of Computer Engineering and Institute of Biomedical Engineering have achieved a major technological breakthrough in the field of medical robotics.
