Bats Build Mental Maps Of Their Surroundings And Remember Them For Future Flights. Many species of bats use echolocation to orient themselves and to hunt their insect prey, but they also rely on a pretty detailed memory to find their way around, a new study suggests.

Scientists form new nerve cells. The field of cell therapy, which aims to form new cells in the body in order to cure disease, has taken another important step in the development towards new treatments.
A new report from researchers at Lund University in Sweden shows that it is possible to re-programme other cells to become nerve cells, directly in the brain. Two years ago, researchers in Lund were the first in the world to re-programme human skin cells, known as fibroblasts, to dopamine-producing nerve cells – without taking a detour via the stem cell stage. The research group has now gone a step further and shown that it is possible to re-programme both skin cells and support cells directly to nerve cells, in place in the brain. Geneticists Estimate Publication Date of The Iliad. This story was originally published by Inside Science News Service.
(ISNS)—Scientists who decode the genetic history of humans by tracking how genes mutate have applied the same technique to one of the Western world's most ancient and celebrated texts to uncover the date it was first written. The text is Homer's "Iliad," and Homer -- if there was such a person -- probably wrote it in 762 B.C., give or take 50 years, the researchers found. The "Iliad" tells the story of the Trojan War -- if there was such a war -- with Greeks battling Trojans. The researchers accept the received orthodoxy that a war happened and someone named Homer wrote about it, said Mark Pagel, an evolutionary theorist at the University of Reading in England.

ET. CAPE CANAVERAL, Fla. — A privately built unmanned spacecraft launched for NASA by the commercial spaceflight company SpaceX blasted into orbit Friday (March 1), but has experienced some sort of malfunction after separating from its rocket, the company says. The robotic Dragon space capsule launched into orbit atop SpaceX's Falcon 9 rocket in what appeared to be a smooth liftoff from a pad at Cape Canaveral Air Force Station in Florida at 10:10 a.m.
ET (1510 GMT). But once in orbit, SpaceX officials reported a problem just after spacecraft separation, when the Dragon capsule was expected to deploy its solar arrays. X's Reusable 'Grasshopper' Rocket Makes Highest Flight Yet. A private experimental rocket that could lay the foundation for a fully reusable launch system has passed its most ambitious test yet, flying 24 stories high and then sticking its landing.

EDT (1634 GMT). Using the station's 58-foot long (18-meter) robotic arm, astronauts aboard the station plucked Dragon from its berthing port and released it into orbit at 6:56 a.m. EDT (1056 GMT) as the ships sailed 252 miles (406 km) above the planet south of Australia. Flight controllers with privately owned Space Exploration Technologies, or SpaceX as the company is known, then stepped in and remotely commanded Dragon to fire its steering thrusters to leave the station's orbit. "It looks beautiful from here," station flight engineer Thomas Marshburn radioed to Mission Control in Houston as the capsule flew away. Curiosity Is Awake Again And On The Path To Recovery.
