Long stretches of DNA once considered inert “dark matter” of the genome — the over 98% of DNA that doesn’t code for proteins — appear to be uniquely active in a part of the brain known to control the body’s 24-hour cycle, according to researchers at the National Institutes of Health. The findings appear in the August 14th edition of the journal Proceedings of the National Academy of Sciences [1].
We are all familiar with the negative consequences of getting too little sleep, but they may be more serious than just feeling a bit groggy. A new study published in the journal Science Translational Medicine has shown that sleep restriction, along with a disruption of one’s internal body clock, can raise the risk of obesity and type 2 diabetes [1]. This could explain the increased rates of these conditions in shift workers and others who work at night.
