Research done by Barbara Kahn, professor of medicine at Beth Israel Deaconess Medical Center, and colleagues now shows that glucose uptake by fatty tissue is important for maintaining the body’s…

In one type of fruit fly, Drosophilia melanogaster, but not in others, researchers found a gene that carries instructions for making a motor that gives this species’ sperm extra horsepower.…

More than 50 percent of colon cancers can be prevented through lifestyle changes and regular screening tests. The lifestyle changes are the same ones that reduce your risk of heart…

Professor Jun Liu studies repetitive patterns in the DNA that lies between genes. This material contains instructions for regulating the expression of genes, and it is involved in whether the…

The French government in 1998 decided to temporarily suspend hepatitis B vaccine programs in schools after several cases of multiple sclerosis were reported a few weeks after the vaccine had…

So cells can differentiate and maintain their specialized identities, large sections of unneeded genes must be turned off. During cell division, the stability of every chromosome depends upon sections of…

“Our research suggests that women can reduce their risk of thrombotic stroke by up to 48 percent by eating fish two to four times per week,” said Kathryn M. Rexrode,…

In 1993, Harvard researchers Dennis Selkoe and Howard Weiner got together over dinner to talk about how they might combine their expertise to find a better treatment for Alzheimer’s, a…

Familial dysautonomia is a neurodegenerative disease that mainly targets Ashkenazi Jews. The disease, which affects one in every 3,600 members of this group, impairs the development of the sensory and…

Although they have not yet identified the actual gene, researchers have evidence that a gene located on human chromosome 10 could be more potent than previous risk factors for late…

Men who give blood reduce the amount of iron in their bodies, but that does not result in a reduction in their risk of coronary heart disease (CHD) and heart…

A study asked parents to observe and record their children’s mouthing behavior over five non-consecutive days. Approximately 300 children showed a wide range of mouthing behaviors, from essentially none at…

“Before the development of insulin, diabetes was as deadly as many cancers are today,” says Harvard researcher Joseph Paul Eder, who is testing Endostatin on patients with advanced cancers. “In…

Abuse can damage the developing brain. Harvard researchers working at McLean Hospital in Belmont, Mass., have identified four types of brain abnormalities identified with abuse and neglect experienced in childhood.…

In findings published in the December 2000 issue of Nature Neuroscience, a team of Harvard Medical School scientists found that people who stay up all night after learning and practicing…

Irritability, anxiety and physical tension, plus decreases in appetite and mood, were experienced by regular marijuana users who quit the drug for four weeks during a study conducted at McLean…

A little worm called Caenorhabditis elegans was the first creature to have all its genes sequenced, more than 19,000 of them. When the human genome was sequenced, researchers found that…

When its aging gene is not working right, a worm named C. elegans lives three times longer than normal, according to Harvard researcher Gary Ruvkun. The development gene keeps an…

The Web site of the American Music Therapy Association lists 57 pages of research articles published in its Journal of Music Therapy and other publications. The articles chronicle successful use…

In studies at Beth Israel Deaconess Medical Center and Dana-Farber Cancer Institute in Boston, tumors were eliminated in 25 percent of patients with widespread kidney and lethal skin cancers who…

For years, scientists have been stymied in their quest to understand dreams because they are unique events that cannot be replicated.

“Arts advocates need to stop making sweeping claims about the arts as a magic pill for turning students around academically,” says Lois Hetland, project manager of the largest, most comprehensive…

Of the more than 1,500 infants who get HIV from their infected mothers every day, 95 percent live in developing countries where the poverty level is high. Many mothers in…

Until now, no one knew the specific trigger that controls the extent to which cells called preadipocytes turn into fat cells. Harvard researchers have identified the genes GATA-2 and GATA-3…

In a major leap toward learning the basics of human biology and what makes it go awry, Harvard researchers have built the prototype of a high-tech chip that rapidly identifies…

Until now, the brain was assumed to be a side player in diabetes. “For the most part, diabetes researchers have not been looking at the brain,” said C. Ronald Kahn,…

“We don’t have any way of curing these problems,” says Nancy Joyce, a Harvard researcher who is working on saving people’s sight when their corneas deteriorate. “The only way right…

In an experiment, healthy men were placed on ventilators, and their ability to take deep breaths was controlled. As their breathing was regulated, their brains were imaged using a PET…

During the course of a 14-year study, female participants’ consumption of red meat dropped by nearly 40 percent, intake of trans fats dropped by more than 30 percent, and use…

“Hypnosis has a contentious history,” notes Stephen Kosslyn, professor of psychology at Harvard and leader of a study in which people were hypnotized to see color where only shades of…
