Molecular structure key to allergies and asthma is identified
Northwestern University and Harvard Medical School researchers have identified the structure of the interaction complex of two molecules that are central to the allergic response.

Studies: Sigmoidoscopy fails to show proportion of colon cancers, polyps
Two studies reported in Thursday's (July 20) New England Journal of Medicine support what many doctors already believed -- that colon cancer screening known as sigmoidoscopy fails to detect a substantial proportion of symptom-free cancers and polyps that may turn cancerous.

Immunologist at the Children's Hospital of Philadelphia receives national award in clinical laboratory immunology
Steven D. Douglas, M.D., director of the Section of Immunology at The Children's Hospital of Philadelphia, was selected to receive the Erwin Neter Award of the Association of Medical Laboratory Immunologists (AMLI).

Flesh-eating robots
The future could be hungry flesh-eating robots. The first robot to be completely powered by food is set to make his public debut next month, by it's inventor from the University of Florida.

Researchers determine improved pattern for artificial light-harvesting molecule
Researchers at the University of Rochester have computed what seems to be the most efficient configuration for one class of tree-like molecules that might someday play a key role in a number of processes, from releasing a drug inside the body to converting light to energy more efficiently than Mother Nature.

Product design and drug development breakthroughs help the environment
The 2000 Presidential Green Chemistry Challenge Awards, recently announced by the White House and the U.S.

Zoonotic diseases symposium focus
Close relationships between people and companion animals can present some hazards, chiefly in the form of parasitic and infectious diseases that can be spread by animals to people.

Unearthing the secrets of human skeletal remains
Australian police stand to benefit from new research at Adelaide University which aims to find the best methods for detecting human skeletal remains of murder victims who have been buried in the unique Australian environment.

University of Chicago neurologist, LPGA team up to study golf and the brain
On July 22-23, a few foursomes of professional women golfers will lend their minds to University of Chicago neuroscientists to help them understand how adults learn complex new skills and how rehabilitation strategies can be improved for people recovering from damage to the brain, such as a stroke.

Brain contains cocaine-like chemical
A team of neuroscientists at the Yerkes Regional Primate Research Center have found that a neurotransmitter produces behaviors associated with cocaine and methamphetamine.

Out of the vortex
A dangerous phenomenon that can flip an aircraft over in flight may have been defeated by two engineers from Boeing in the US.

New advance in radiation therapy may improve cancer treatment
At an international conference in Chicago, medical physicists will describe an innovative new technique known as

Why proteins spiral
Why do proteins coil up into spirals? A simple explanation-- based solely on principles of geometry--for the protein's preference for the helix as a major component of its overall structure is expected to be useful in such research areas as structural genomics, pharmaceuticals, protein engineering, and materials science.

Scientists look to nature to cut greenhouse emissions
Ohio University scientists are developing a cleaner and less expensive method of reducing greenhouse gas emissions from coal-fired power plants.
