“Robojelly” mimicks the action of the jellyfish, which uses a circular muscle to open out a bell-like body and then sharply close it, which expels water and moves the creature forward. This undated photo released by the BMDL and CEHMS labs at Virginia Tech in Blacksburg, Virginia, show the robo

A group of U.S. scientists have discovered how a mutation in a particular gene can lead to uncontrolled eating, which can lead to obesity, Science Daily reported Sunday.Previous studies have revealed that the brain-derived neurotrophic factor (BDNF) gene is linked to obesity, but no one could explain how it controls the impulse to eat.Georgetown university researchers discovered in a new study that a mutation in the BDNF gene in mice does not allow brain neurons to communicate to each other. It

When you find your mind drifting away while doing mundane tasks, you can take a pride in your brain functions. A recent study shows that people with higher working memory tend to let their minds wander while doing routine jobs. It also allows working memory to exercise, Livescience.com reported Friday.Working memory allows the brain to process several thoughts at once, allocating resources to the imminent problems, according to the study by the Max Planck Institute for Human Cognitive and Brain
