Cats are one of, if not the most, popular pet in the world. There are over 500 million domestic cats in the world. Cats and humans have been associated for nearly 10000 years. Cats conserve energy by sleeping for an average of 13 to14 hours a day. Cats have flexible bodies and teeth adapted for hunting small animals such as mice and rats. A group of cats is called a clowder, a male cat is called a tom, a female cat is called a molly or queen while young cats are called kittens. Domestic cats usually weigh around 4 kilograms (8 lb 13 oz) to 5 kilograms (11 lb 0 oz). The heaviest domestic cat on record is 21.297 kilograms (46 lb 15.2 oz). Cats can be lethal hunters and very sneaky, when they walk their back paws step almost exactly in the same place as the front paws did beforehand, this keeps noise to a minimum and limits visible tracks. Cats have powerful night vision, allowing them to see at light levels six times lower than what a human needs in orde

DARPA Wants to Zap Your Brain to Boost Your Memory We may go to sleep at night, but our brains don't. Instead, they spend those quiet hours tidying up, and one of their chores is to lug memories into long-term storage boxes. Now, a group of scientists may have found a way to give that memory-storing process a boost, by delivering precisely timed electric zaps to the brain at the exact right moments of sleep. These zaps, the researchers found, can improve memory. And to make matters even more interesting, the team of researchers was funded by the Defense Advanced Research Projects Agency (DARPA), the U.S. agency tasked with developing technology for the military. They reported their findings July 23 in The Journal of Neuroscience. If the findings are confirmed with additional research, the brain zaps could one day be used to help students study for a big exam, assist people at work or even treat patients with memory impairments, including those who experienced a traumatic brain
