Pitt, VCU researchers find genetic link to bulimia nervosa

A team of researchers at Virginia Commonwealth University (VCU) and the University of Pittsburgh Medical Center have linked an area of chromosome 10p to families with a history of bulimia nervosa, providing strong evidence that genes play a determining role in who is susceptible to developing the eating disorder.

The finding, gleaned from blood studies of 316 patients with bulimia and their family members, is the result of the first multinational collaborative genome-wide linkage scan to lo

More Sun-like stars may have planetary systems than currently thought

Study of planetary disks around T Tauri stars

If David Weintraub and Jeff Bary are right, there may be a lot more planets circling stars like the Sun than current models of star and planet formation predict.
The associate professor of astronomy at Vanderbilt and his graduate student are taking a critical look at T Tauri stars. These are stellar adolescents, less than 10 million years old, which are destined to become stars similar to the Sun as they age.

Search for cholesterol absorption genes narrows to two chromosome regions

Findings with lab mice may lead to novel cholesterol-lowering drugs against heart disease

Two people eat the same egg, cheese and ham muffin for breakfast, yet one absorbs significantly more cholesterol into his or her blood than the other. Why?
The answer, and all of its implications for combating heart disease, remains stubbornly hidden within our DNA. In recent genetic studies with lab mice, however, researchers at The Rockefeller University have begun to close in on the culpr

New System Created by Rensselaer Researchers Speeds the Mapping of Blood Vessel Networks in Live Tumors

Rensselaer researchers have developed an automated system, called RPI-Trace3D, that can swiftly map capillaries in a live tumor. What used to take days of manually tracing the vessels, now takes two minutes. The diagnostic tool, in use at Harvard Medical School and at Northeastern University, is a boon to oncologists who aim to understand how blood vessels form in tumors.

For the first time, medical scientists can quickly and precisely measure blood vessel properties to quantify the effects

Search for sympathy uncovers patterns of brain activity

Neuroscientists trying to tease out the mechanisms underlying the basis of human sympathy have found that such feelings trigger brain activity not only in areas associated with emotion but also in areas associated with performing an action. But, when people act in socially inappropriate ways this activity is replaced by increased activity in regions associated with social conflict.

Understanding the neurophysiology of such basic human characteristics as sympathy is important because some peo

Caught sleeping: Study captures virus dormant in human cells

Cytomegalovirus, hidden in most people, begins to give up secrets of its stealth

Princeton scientists have taken an important step toward understanding a virus that infects and lies dormant in most people, but emerges as a serious illness in transplant patients, some newborns and other people with weakened immune systems.

The virus, called human cytomegalovirus, enters the bone marrow and can hide there for a lifetime. Until now, however, scientists had not been able to stud
