A dietary supplement in the form of a cheap, fortified, orange-flavored drink can reduce Third World deficiencies in micronutrients such as iron, iodine and vitamin A, a Cornell University physician and international nutritionist reports. The supplement, he says, eases the so-called “hidden hunger” that plagues more than 2 billion people worldwide and particularly affects pregnant and nursing mothers and young children.

Researchers at Washington University School of Medicine in St. Louis are developing methods to track molecular events in the body to diagnose disease long before symptoms appear and to predict the effectiveness of drug therapies. The research is under way at the School of Medicine’s new Molecular Imaging Center at the Mallinckrodt Institute of Radiology. The Center is funded by a five-year $9.4 million grant from the National Cancer Institute.

“Molecular imaging combines the latest in

Researchers at Washington University School of Medicine in St. Louis are transplanting jellyfish genes into mice to watch how neural connections change in the brains of entire living animals. The development represents the merging of several technologies and enable researchers to watch changes inside living animals during normal development and during disease progression in a relatively non-invasive way.

“This work represents a new approach to studying the biology of whole, living animals,

A physical chemist at Washington University in St. Louis is combining powerful lasers with clever timing schemes to characterize how chemical reactions occur with very precise atomic and time resolution. Understanding the mechanisms and physics of a chemical reaction at the most fundamental level could provide valuable insights into new directions for the field of chemistry.

Richard A. Loomis, Ph.D., assistant professor of chemistry, is a physical chemist building on the femtochemistry adv

Physicists have devised a new experiment that will be used in the quest for exotic forces in nature and “additional spatial dimensions.”

The researchers have demonstrated an innovative way to measure a phenomenon known as the Casimir effect – findings that also could have implications for the design of microscopic machines that contain tiny parts on the size scale of nanometers – or billionths of a meter.

The scientists are taking their theoretical findings a step further by

A new study of the most commonly prescribed post-kidney transplant drug suggests it may not be the most effective weapon to fend off organ rejection and may even damage some donor kidneys. The research, to be presented Nov. 2 at the American Society of Nephrology annual meeting, identified another drug that seems to work better, a finding that could help expand the pool of donor organs.

An analysis by an Ohio University physiologist suggests that large doses of cyclosporine, the most often
