While humans and mice look and act very differently, 85 to 90 percent of our genes are the same or similar. So if scientists can understand the instructions in every mouse gene, people will get a good idea of the instructions in virtually every human gene as well.
For people with a peanut allergy, just being near people who eat peanuts and products made from them can trigger a serious allergy.
This contact lens (right), about the size of a U.S. quarter, can magnify a wearer’s vision 2.8 times. Such lenses would let a patient switch, in the wink of the eye, between normal and magnified vision.
Humans and mice look and act very differently. But 85 to 90 percent of their genes are the same or quite similar. So an international group of scientists is deciphering the instructions in mouse genes to help us better understand our own.
Certain types of fiber suppress appetite, at least in mice. Found in fruits, vegetables, oats and barley, this fiber breaks down in the gut to release acetate. That travels to the brain, where the chemical prompts the release of hunger-fighting hormones.
Scientists thought that cave art started in Europe. New analyses now dash that assessment. Stencils in an Indonesian cave are every bit as old as the better-known drawings in caves in France and Spain.
