Germs in the gut linked to appetite

Germs in the gut may help drive appetite, says new research into the link between obesity and bacteria. Previous studies have shown that overweight people and normal-weight people harbor different types and amounts of microbes that naturally live in the intestine. To determine why, scientists are peering into mice.

Mark Nicas has given some of his best years to spittle. He builds models – the mathematical kind – of how someone else’s slobber ends up on you. The size of the particles, whether they come out in a dry cough or a wet sneeze, their evaporation rate, air speed – these are all complications, reasons why people like Nicas can spend careers piling up academic papers, all the while building up a healthy respect for pathogens.

Washing Your Hands Can Save Your Life
