Environmental health researcher studies lead poisoning in India
Lead is a naturally occurring toxic element, and exposure poses a serious threat to children whose neurological systems are still developing. Some children suffer from brain damage, poor motor skills coordination, and damaged kidneys. But the disease is easily preventable by limiting exposure to the toxic substance. More than 100 million people in India battle…

First indications that aging may be regulated by brain
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 C. elegans shares about 40 percent of its genes with human beings. Two such genes — with potentially important consequences for humans — were recently…

Tiny creatures offer clues to human aging
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 animal forever youthful in the sense that it never develops into a reproducing adult. There is a corresponding human gene, opening up fascinating possibilities. Worms…

How family leave policies fail working families
In her book, “The Widening Gap: Why American Working Families are in Jeopardy and What Can be Done About It,” S. Jody Heymann of the Harvard School of Public Health analyzed survey data to describe the “national caregiving burden.” She has exposed the growing gap between demands on parents and resources provided by government and…

Treating ills with music
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 of music, in combination with other therapies, to treat Alzheimer’s and Parkinson’s diseases, depression, anxiety, chronic pain, pain of childbirth, autism, and other physical and…

New cancer vaccine being tested
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 received a new cancer vaccine. Another 25 percent showed encouraging shrinkage of large and small tumors. Some of the 75 people who have received the…

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

Brain found to play unexpected role in Type II diabetes
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, the Mary K. Iacocca professor of medicine and president of Joslin Diabetes Center. But a report appearing in the Sept. 22, 2000, Science suggests that…

Sights set on partial corneal transplants
“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 now is full corneal transplantation, healthy tissue and all. In our work, we’re trying to facilitate replacement of the diseased tissue only.” To do that,…

Hypnosis found to alter the brain
“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 gray exist, and to see gray when actually looking at brightly colored rectangles. “Some insist it’s a state of mind that differs from normal states…

Tissue engineering produces an artificial gland
Your thymus is a walnut-sized gland that sits just above your heart. The master gland of the immune system, one of the thymus’ chief functions is to produce T lymphocytes, which are a type of white blood cell that works to prevent disease. In July 2000, a team of Harvard Medical School researchers at Massachusetts…

Fighting prostate cancer with radioactive seeds
In November 1997, a team of surgeons headed by Anthoy D’Amico, an associate professor of radiation oncology at Harvard Medical School, first used a technique that treats early stages of prostate cancer in a way that, for some patients, may be superior to the usual methods of surgical removal of the gland or seven weeks…

Men have distorted image of what women find attractive
Asked by researchers to choose the bodies they would most like to have, male college students in a study picked computer images with 30 pounds more muscle than they actually had. Asked to select their most-wanted body from the same computer images, female college students chose men with 15 to 30 pounds less muscle than…

Study points to more targeted use of Ritalin
An area known as the putamen, located deep in the center of the brain, helps to control movement and attention. Harvard researchers believe that the putamen is involved in Attention Deficit/Hyperactivity Disorder. The finding also suggests that Ritalin may not be effective in treating ADHD. When researchers examined hyperactive, inattentive boys with a new type…

Researchers face up to liars
What category of people do you think would be best at detecting lies? It’s not Secret Service agents, or psychiatrists, or even mothers. Investigators working at Massachusetts General Hospital in Boston have found that aphasics — people who, because of stroke or other forms of brain damage, have been robbed of their ability to understand…

Birth of new brain cells induced in birds
Stem cells that are naturally present in the brains of finches were induced to replace lost cells and restore the birds’ ability to sing their distinctive song. “Our results represent the restoration of a brain circuit involved in a complex learned behavior,” says Jeffrey Macklis, associate professor of neurology in the Division of Neuroscience at…

Shadow proteins in thymus may explain how immune system gets to know its own body
Researchers recently identified a protein that appears to work by turning on in the thymus, which lies beneath the breast bone, the production of a wide array of proteins from the body’s periphery. The discovery of the protein called “aire” could shed light not only on how the healthy immune system develops tolerance to its…

Researchers switch cancer off and on in mice
An antibiotic added to the drinking water of mice stops the progress of leukemia. Harvard researcher Claudia Huettner cannot do the same thing in humans, unfortunately, but through such experiments Huettner and her colleagues are gaining an understanding of how human leukemias arise. The new knowledge they have gained is providing them with a means…

Study says children with cancer often suffer needlessly
“Since caregivers are very committed to curing their patients, it may be difficult for them to recognize when to incorporate palliative care into treatments, even when there’s little hope of cure,” notes Joanne Wolfe, an instructor at Harvard Medical School and lead author of a report, published in The New England Journal of Medicine, that…

‘Take two aspirin and call me manana’
Harvard Medical School is attempting to bridge the language barriers that sometimes arise in medical settings.

Electromagnets used in treating depression
Recent studies by Harvard researchers at McLean Hospital in Belmont, Mass., have enlarged the body of knowledge about a promising, though still experimental, treatment for a variety of psychiatric disorders. The treatment is called “transcranial magnetic stimulation,” and essentially involves placing a powerful electromagnet on a person’s scalp. The electromagnet alters brain activity by inducing…
