Changing fish body shapes give clues to environmental factors
The placement of the mouth, the length of the tail - these and other traits in fish are showing researchers how an ecosystem can lead a species to evolve in its quest for survival.

Telemedicine link with South Pole allows remote knee surgery
In a groundbreaking telemedicine development, doctors in Massachusetts earlier this month helped a physician at Amundsen-Scott South Pole Station to surgically repair the damaged knee of a meteorologist spending the winter in Antarctica.

Quick blood test for heart failure proves successful in multinational trial
In a trial of nearly 1,600 patients in the United States and Europe, a 15-minute blood test enabled emergency-room doctors to correctly diagnose congestive heart failure in 9 out of 10 cases--without relying on costly, time-consuming tests such as echocardiograms and chest X-rays.

Stem cells could determine how long we live
How long we live could depend on how hardy our stem cells are.

Healthy dessert: 'peaches and phytochemicals'
Peach cobbler. Peaches and cream. Peaches and antioxidants? Dessert with this fleshy fruit is healthier than expected, researchers are finding.

Rose breeding blooms from backyard to genetics lab
The backyard garden of a mathematician has rejuvenated Texas rose research in a way that could lead to improvements not only for the flowering bush but also for some berry crops.

MIT technique could improve cartilage repair
MIT engineers are excited about a new technique for repairing cartilage that could have significant advantages over the procedure now commonly used.

Hormone prompts adult stem cells to differentiate into islet cells
Scientists at Massachusetts General Hospital have discovered that a naturally occurring hormone can cause adult islet stem cells to mature into pancreatic beta cells, the insulin-secreting cells that are depleted or compromised in diabetes.

Emory brain imaging studies reveal biological basis for human cooperation
Functional MRI scans have revealed a

Rare childhood bone disorder linked to gene deletion in two Navajo patients
Two seemingly unrelated Native American children have one painful thing in common: juvenile Paget's disease (JPD), an extremely rare, bone metabolism disorder.

Medicare+Choice bills may stop exodus of plans, but are not likely to expand enrollment in HMOs

Highlights of this issue include an extension of the second law of thermodynamics at microscopic scales, a repeat of the famous Millikan oil drop experiment, transformations of diamond from one form to another and making better lithium batteries.

Genetic studies shed light on the malaria parasite's origins and drug resistance
New data show the malaria parasite P. falciparum is genetically more diverse and at least 100,000 years older than some scientists have thought and that drug resistance arose and spread rapidly across several continents, according to two NIH studies appearing in Nature.

Scientisist to study changes in highest clouds via satellite
Scientists at the University of Alaska Fairbanks Geophysical Institute will be teaming with those at ten other institutions to take part in the Aeronomy of Ice in the Mesosphere (AIM) mission over the next six years.

Hot Interconnects 2002 Conference to be held Aug. 21-23 at Stanford University
Hot Interconnects 2002 will be held at Stanford University this year between August 21-23.

Genetic variant reduces immune response, yet protects against atherosclerosis
An international team led by Duke University Medical Center researchers has discovered that a genetic variant of an immune system receptor appears to simultaneously dampen the body's immune response to bacteria and other microbial toxins and to provide some protection against atherosclerosis, or clogging of the arteries.

Society for Women's Health Research, U. of Wisconsin scientific meeting on cardiovascular disease
To raise awareness of the leading killer and encourage the understanding of key differences between women and men with regard to heart disease, the Society and the University of Wisconsin Medical School are hosting
