When young adults start working, the amount of daily physical activity they do increases sharply, only to fall away again over the next few years, while the amount of sleep they get falls slightly, according to new research led by scientists at the University of Cambridge.
Researchers have used the chemical fingerprints of zinc contained in meteorites to determine the origin of volatile elements on Earth. The results suggest that without ‘unmelted’ asteroids, there may not have been enough of these compounds on Earth for life to emerge.
An international team of researchers has found a genetic variant that may explain why some people of African ancestry have naturally lower viral loads of HIV, reducing their risk of transmitting the virus and slowing progress of their own illness.
Cognitive impairment as a result of severe COVID-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, say a team of scientists from the University of Cambridge and Imperial College London.
