 A steaming mug of coffee helps me wake up in the morning.But it can do more than just keep your eyes open. Caffine may actually boost 1 your memory. Researchers gathered 160 uncaffinated adults, people who consumed less than 500 milograms of caffine in a week. These decaf subjects looked at pictures of various objects then took either a placible or a pill containing 200 milograms of caffine. That's roughly the amount you'd get from two cups of coffee. The next day, participants examined a fresh set of pictures. Some brand new, some from the previous day and some that just looked similar to the old images. Both groups could identify new and old pictures eaqually well. But the caffinated group is better at correctly labeling images that were similar but not identical. The placible group tended to mistakenly identify these pictures as the same as the previous days. The work is in the  journal Nature Neuro Science. So caffine does more than help you stay alert 2. Get the picture? The study subjects did.
