Studies in various animals, including rodents and monkeys, have reported that caloric restriction can extend their lifespans. Findings from a two-year, randomized, controlled trial with human participants, published last week (March 22) in Cell Metabolism, suggest that cutting down on calories may also be able to prolong the lives of people.
A genetic mutation that may protect people from malaria, but was thought to be rare, is surprisingly common, suggest the findings of a new study led by scientists at The Scripps Research Institute (TSRI). The discovery sheds light on how humans who live in close quarters with malaria-carrying mosquitos may evolve defenses against the disease.
In the perennial question of nature versus nurture, a new study suggests an intriguing connection between the two. Salk Institute scientists report in the journal Science that the type of mothering a female mouse provides her pups actually changes their DNA. The work lends support to studies about how childhood environments affect brain development in humans and could provide insights into neuropsychiatric disorders such as depression and schizophrenia.
