Calorie burn is about 10% greater in the late afternoon-early evening time period, according to findings published in Current Biology. Researchers sequestered volunteers in a windowless lab without access to phones or internet for over a month to measure their metabolic rate based on their internal clocks.
The Blavatnik Family Foundation has given a $200 million gift to Harvard Medical School, the largest donation ever received by the school, for a wide range of medical research projects with the aim of producing treatments more quickly.
