New York: Although long life tends to run in families, genetics has far less influence on life span than previously thought, according to a new analysis of an aggregated set of family trees of more than 400 million people. The study suggests that the heritability of life span is well below past estimates, which failed to […]

New York: You can blame your genes for your obesity as researchers have found 13 genes that carry variations associated with body mass index (BMI). The researchers identified 14 genetic variations in 13 genes, including a risky copy variation — a phenomenon in which sections of the genome are repeated — that causes carriers to […]

New York: A study of birds, which live on the Galapagos Islands in the Pacific Ocean, has shown direct genetic evidence that new species can arise in just two generations. The findings, published in the the journal Science, are based on a study of a “strange” bird that arrived on a remote island in the […]

New York: Researchers at Weizmann Institute of Science in Israel have identified around 6,500 genes that are expressed — copied out to make proteins — differently in men and women. The detailed map of these genes, reported in the journal BMC Biology, suggests that males and females undergo a sort of separate, but interconnected evolution. […]

New York: Unsupportive parenting styles may have several negative health implications for children including premature ageing and higher disease risk later in life, says a study. The research found that the telomeres — protective caps on the ends of the strands of DNA — of participants who considered their mothers’ parenting style as “cold” were […]

New York: A specific gene makes certain compounds taste bitter, which may make it harder for some people to add heart-healthy vegetables to their diet, according to a new study. “Your genetics affect the way you taste, and taste is an important factor in food choice,” said study author Jennifer L. Smith from University of […]
