A new procedure being used by Emory University physicians, called CardioSEAL®, can close a variety of intracardiac holes in about half an hour.

Low-income, hungry children sick more often
It is generally accepted that not getting enough to eat has severe consequences for children in countries poorer than the United States, but this is the first national U.S. study to determine if the level of food deprivation domestically is severe enough to affect children's health status.

Blisters to the feet, a mere annoyance for most people, are a grim and sometimes life threatening danger for diabetics, whose ulcerations can be so serious that they require amputation of the lower leg.

Researchers pinpoint how tubeworm babies are dispersed to colonize new vent sites
Scientists have wondered how tubeworms, which are sessile creatures and can't move about, wind up at new hydrothermal vent sites on the ocean floor.

Research project to help pharmaceutical industry examine molecular structure of pills
Two Syracuse University researchers are conducting research to develop a new tool for the pharmaceutical industry that will more closely examine the molecular structure of pills -- potentially aiding companies in developing safer and more effective medications.

LSU program for graduate education could become model for U.S.
LSU is developing a new multidisciplinary, craft-based approach to graduate education that could serve as a model for graduate programs around the country.

UF researchers find ethnic differences in reports of pain perception
The intensity with which pain is felt varies widely, colored by past experience, insomnia, cultural conditioning, and fundamental biologic or psychological makeup.

Study raises questions about relationship between sudden infant death syndrome and events detected by home monitors
The use of home monitors to detect prolonged cessation of breathing or a slower than normal heart rate in infants are not an effective means of preventing sudden infant death syndrome (SIDS), a study by a Yale researcher has found.

Lipoprotein lipase: Location, location, location.
Many extracellular proteins bind avidly to heparin in vitro, reflecting their affinity, in a physiological setting, for the long polysaccharide side chains of heparan sulfate proteoglycans (HSPGs).

Proteins are vastly more complicated than previously realized
Proteins and cells are locked together at numerous contact points.
