In a study, researchers obtained cow oocytes (donor eggs from cow ovaries) and removed and discarded the nuclei, which contain the cells’ genetic material, leaving behind just the shell. A…
Scientists have known the identity of two genes that can influence the ability of insulin genes to trigger insulin production in the beta cells of the pancreas. Through subsequent research…
Scientists have known about the longevity benefits of caloric restriction since experiments in the 1930s showed that rats lived much longer if their food intake was severely restricted. Broadly speaking,…

Clinicians have known for years that organs function at different rates — the heart beats, kidneys transport ions and electrolytes, the liver metabolizes lipids, sugars, and amino acids differently over…
Milk intake has decreased significantly over the past three decades while the prevalence of obesity and type 2 diabetes has increased. The authors of a Harvard research study note that…
Harvard Medical School researchers Vadim Bolshakov, Evgeny Tsvetkov, and Bill Carlezon, based at McLean Hospital, reported with colleagues in the April 11, 2002 issue of the journal Neuron that they…
A new technology developed by Harvard Medical School researchers in the laboratory of Yang Shi, associate professor of pathology, extends the range of possibilities of selective interference of gene expression…
Harvard researcher Herbert Benson, who has been studying a meditation technique known as “g Tum-mo” for 20 years, says that “Buddhists feel the reality we live in is not the…
A research report provides a possible explanation for a class of birth defects that appears to be on the rise. A protein normally involved in programmed cell death may, as…
Paul Harris, a professor at Harvard’s Graduate School of Education, says there are two very different ways to define imagination. “You can either see it as disappearing or waning during…
Richard McNally, a Harvard professor of psychology, and his colleagues recruited six women and four men who claimed they had been spirited away by extraterrestrials, some of them more than once.
Age-related macular degeneration is the leading cause of blindness for Americans over 60 years of age. It affects more than 14 million people. But how it attacks the macula, the…
Research has shown that leptin is an important hormone with a hand in many metabolic processes. It undoubtedly has widespread effects that may influence diabetes as well as obesity. Recent…

Researchers are working feverishly to develop an effective vaccine against the AIDS virus. Various vaccines have been tested. One of the more promising vaccine trials involved eight monkeys. When one…
Angiogenesis is the process by which cancer tumors develop a network of blood vessels to feed them, so that they may continue their growth. The strategy that cancer cells use…
Harvard Medical School researchers have discovered that a pigment contained in the egg of the South African claw-toed frog is indispensable for development. Witout the pigment, called biliverdin, which is…
About 2,000 children a year are diagnosed with medulloblastoma, or brain tumor. In a study, researchers examined gene expression patterns from 99 patient tumor samples of three different types of…
