Timing is everything: First step in protein building revealed
Timing is everything, it seems, even inscience. A team led by Johns Hopkins scientists has unraveled the firststep in translating genetic information in order to build a protein,only to find that it's not one step but two.In a series of experiments, the scientists found that when yeast'sprotein-building machinery recognizes the starting line for a gene'sinstructions, it first alters its str...New technology shows our ancestors ate…everything!
Using a powerful microscope and computer software, a team of scientists from Johns Hopkins, the University of Arkansas, Worcester Polytechnic Institute and elsewhere has developed a faster and more objective way to examine the surfaces of fossilized teeth, a practice used to figure out the diets of our early ancestors. By comparing teeth from two species of early humans, Australopithecus a...Everything in its place: Researchers identify brain cells used to categorize images
Socks in the sock drawer, shirts in the shirt drawer, the time-honored lessons of helping organize one's clothes learned in youth. But what parts of the brain are used to encode such categories as socks, shirts or any other item, and how does such learning take place?
