Your microbes might decide how much you weigh

Microbes—usually bacteria, fungi, or protists—made a big splash of news when the White House Office of Science and Technology Policy announced the new National Microbiome Initiative (NMI) last month. The NMI’s aim is to advance the understanding of microbiome, which refers to all the microbes in a particular environment. The initiative particularly focuses on restoring […]

Parasitic worms could treat obesity disorders

On the list of unwelcome medical conditions, a parasitic worm infection ranks fairly high. But according to an international team of scientists, the sugar-based anti-inflammatory molecule that many parasitic worms secrete inside the human body might actually help treat the metabolic disorders associated with obesity. The researchers, from the University of Georgia, the Harvard School […]
