Emre Basar seeks to understand how small interfering RNA (siRNA) can be harnessed and integrated into cells with the goal of silencing the expression of certain proteins that allow diseases like breast cancer and HIV to proliferate inside the body.

A new Harvard study shows that ratios between males and females affect human longevity.

Expectant mothers who gain large amounts of weight tend to give birth to heavier infants who are at higher risk for obesity later in life. But it’s never been proven that this tendency results from the weight gain itself, rather than genetic or other factors that mother and baby share.

New research from Harvard scientists shows that exercise and caloric restriction rejuvenate synapses in laboratory mice, illuminating a reason for the beneficial effects of these regimens on aging.

Harvard researchers have uncovered a mechanism in mice through which caloric restriction and exercise delay some of the debilitating effects of aging by rejuvenating the connections between nerves and the muscles that they control.

Small increases in vaccine costs can cause large gaps in protection, study finds. Also, vaccine “scares” may do more harm than previously believed to a population’s “herd immunity.”

A rare and curious plant from Sumatra’s rainforest has bloomed at Harvard.

Implementing a program of universal HIV testing and immediate antiretroviral treatment (ART) for infected individuals could have a major impact on the HIV/AIDS epidemic in Washington, DC, but a new study by led by…

Study finds that maternal genes in mice predominate in the developing brain, while paternal genes gain the upper hand in adulthood. Researchers also find 1,300 imprinted genes in the brain, far more than previously known.

Genome-wide analysis of mice brains has found that maternally inherited genes are expressed preferentially in the developing brain, while the pattern shifts decisively in favor of paternal influence by adulthood.…

Users of erectile dysfunction (ED) drugs have higher rates of sexually transmitted disease (STD) than do non-users, Harvard researchers at Massachusetts General Hospital have found after analyzing insurance records of…

More than two billion people worldwide do not have adequate access to surgical treatment, according to a new study from the Harvard School of Public Health (HSPH). The Harvard researchers…

Rare variants in the gene coding of an enzyme that controls the activity of a key immune cell occur more often in people with autoimmune disorders like rheumatoid arthritis and…

Fasting helps cause an enzyme with several important roles in energy metabolism to turn off the body’s generation of fats and cholesterol, Harvard researchers at Massachusetts General Hospital have found. …

Harvard and Brigham and Women’s Hospital researchers have devised a method that may allow clinicians to use higher doses of a powerful chemotherapy drug that has been limited because it is toxic not only to tumors but to patients’ kidneys.

Researchers, led by Harvard Medical School Assistant Professor Shiladitya Sengupta, have devised a way to improve a low-cost, effective cancer drug, cisplatin, whose use has been limited by its toxicity.

Researchers gather to share information about the latest advances in understanding how the oldest part of the body’s immune system might help in the fight against HIV and AIDS.

The Glenn Laboratories hosted the annual symposium on aging, reviewing new developments in understanding the mechanisms of growing old.
