Chandra probes nature of dark matter
It’s one of the universe’s most enduring mysteries — what comprises the “dark matter” that scientists believe most of the universe is made of, but which humans have been unable yet to see? Scientists using the Chandra X-ray Observatory were able to precisely determine the distribution of dark matter in a distant galaxy cluster named…

Study shows strong public interest in genetic testing for Alzheimer’s disease
A genetic test to determine a person’s chance of getting Alzheimer’s disease is still hypothetical. But scientists are getting closer and closer to being able to determine who is likely to get the disease. A study by Harvard researchers and their colleagues found that, once such a genetic test is developed, approximately 80 percent of…

One-tenth of medical residents feel unprepared

A surprising one in 10 of medical residents said they felt unprepared to deal with such tasks as the treatment of HIV/AIDS, substance abuse, nursing home patients, management of…

Resistance to antibiotics is reversed
Infectious bacteria that have developed resistance to even the most potent antibiotics are making hospital stays increasingly hazardous. Take the drug vancomycin, for example, which used to be a last line of defense against virulent strains of enterococci and staphylococci that can be life-threatening. These bacteria continually develop new ways to beat vancomycin.

Resistance to antibodies is reversed
It’s a frightening — and increasingly common — problem. A patient seeks treatment for a particular ailment in a hospital and develops an entirely different disease: a bacterial infection that is resistant to antibiotics. Researchers have worked to come up with better and more powerful antibiotics, but even an antibiotic such as vancomycin, which used…

Common aspirin reveals mechanism of insulin resistance
In 1876, a German professor described a treatment that led to rapid improvement in two men who were suffering from what doctors now recognize as classic type 2 diabetes. In the late 1950s, scattered reports about this treatment for diabetes symptoms again appeared in the medical literature; the results were equally dramatic. What was this…

Cell death in eggs traced to smoking
A woman is born with just so many egg cells, called oocytes. When she begins ovulating, she has about 400. Even though that may seem like a lot, considering the few that would ever be fertilized, scientists have found that loss of oocytes influences a woman’s health. Early loss of oocytes leads to early menopause…

Sorting good eggs from bad ones
An oocyte is an immature egg cell in the ovaries. Before a woman is born, her ovaries will contain about five million eggs. At birth, about three million of those egg cells die — apparently by committing suicide. This fact of nature has long puzzled scientists. Now, Harvard researchers working at the Center for Blood…

Medicaid coverage for anti-AIDS drugs would be cost effective
It’s long been said that “an ounce of prevention is worth a pound of cure.” A new study from the Harvard Center for Risk Analysis applies the principle to treating HIV-infected people with antiretroviral drugs, the so-called “AIDS cocktail.” Under Medicare rules, people without health insurance can’t get treatment until they develop full-blown AIDS and…

Harvard scientists identify chromosome location of genes associated with long life
Scientists have long thought of aging as a complex process affected by perhaps a thousand genes. So a recent discovery by Harvard scientists that a gene or genes located on a region of human Chromosome 4 may help people to live to age 100 was something of a surprise. “This is the first study to…

Nutrition book author Willett rebuilds USDA food pyramid
For more than 20 years researchers at Harvard and elsewhere have been looking at the long-term health effects of eating certain types of foods. These researchers now have a good idea what’s good for you and what’s not, and in what quantities. However, that information is not reflected in the “food pyramid” produced by the…

Samantha Power, executive director of the John F. Kennedy School’s Carr Center for Human Rights Policy, conducted a three-year-long investigation into what the United States government knew, didn’t know, and chose to do during the Rwandan genocide in 1994. Based on hundreds of interviews and hundreds of pages of declassified government documents, Power’s conclusion finds…

Drug hits new molecular target in mice
When doctors diagnose and plan treatment for breast cancers they look for various indicators of how aggressive they are and what treatments will work best. Two-thirds of breast tumors are made up of cells that have receptor molecules for estrogen on their cell surface. The growth of these estrogen-receptor-positive (ER+) tumors depends in part on…
