The Magnetic Personality of Ancient Mars - Space.com  A new study of old rocks on Earth could force a revision of theories about Mars. The results suggest ancient Mars might have been more magnetic than thought, challenging basic assumptions about the evolution of the red planet. Unlike modern Earth, Mars has almost no magnetic field today. Evidence has suggested Mars didn't have a very strong magnetic field early on, either.    
US robot builds copies of itself  - BBC  US researchers have devised a simple robot that can make copies of itself from spare parts. Their long-term plan is to design robots made from hundreds or thousands of identical basic modules. Each unit comes with a small computer code carrying a blueprint for the layout of the robot, electrical contacts to let it communicate with its neighbours, and magnets to let them stick together. By turning and moving, the cubes can pick up new units, decide where they belong, and stack them alongside each other to make new devices. In a little more than a minute, a simple three-cube robot can make a copy of itself.

How one small pill could boost your memory  - BBC  The drug CX717 belongs to a family of compounds called ampakines and works by boosting the brain chemical glutamate that makes learning and recall easy. UK trials on 16 sleep-deprived volunteers showed it improved wakefulness and mental ability. Manufacturer Cortex is considering CX717 as a possible treatment for narcolepsy - excessive daytime sleepiness; and attention deficit hyperactivity disorder (ADHD) - a condition which impairs a child's ability to concentrate. It could also be taken by healthy people as a pick-me-up. But it will have to undergo further clinical trials before going on sale.
