After surviving a planned four-day "brain surgery" operation, the most advanced rover yet sent to Mars will take its first drive next week, NASA scientists said Tuesday. The Mars Science Laboratory rover, nicknamed Curiosity, had been stretching its limbs and checking out some of its cameras since it touched down on the Red Planet's surface Aug. 5. This weekend, engineers at Jet Propulsion Laboratory in La Cañada-Flintridge installed fresh software that will arm the rover with the know-how to do its job on Mars.

The Curiosity rover's landing wasn't quite perfect -- but if the Martian robot were an Olympic gymnast, it could earn a gold medal for its gymnastic contortions, according to NASA engineers. The Mars Science Laboratory's climactic Aug. 5 landing essentially happened on autopilot, with scientists and engineers in the control room at Jet Propulsion Laboratory waiting several minutes as the rover's signals traveled the roughly 150 million miles back to Earth. But Curiosity ended up roughly 1.5 miles away from its predicted touchdown zone - not bad, given that their projected landing zone was an ellipse 12 miles wide, mission engineers said Friday.

"Zombie apocalypse," voodoo curses and a potent street drug called "bath salts. " Those are just a few of the angles the media have pursued after the bizarre case of a naked man shot and killed by Miami police as he was eating the face of another man. A less sensational angle? The long, sad journey that awaits the homeless victim, Ronald Poppo, 65, who is believed to have lost about 80% of his face -- including one eye -- in the gruesome daylight attack. Poppo is not likely to get a face transplant, experts say. Such procedures are extremely rare.

Transplants of healthy skin from a patient's own body can improve discoloration caused by vitiligo, researchers from the Henry Ford Health System in Detroit reported Thursday. The procedure was developed in Saudi Arabia, and the Ford researchers are the first U.S. team to attempt it, according to Dr. Iltefat Hamzavi, a Ford dermatologist. Although the study involved only about 30 patients, the pilot trial suggests that the procedure could be beneficial to many patients, he said. Vitiligo is a disease that occurs when the body's immune system kills cells called melanocytes in the skin.

Episcopal Bishop J. Jon Bruno, head of the six-county Los Angeles diocese, has been diagnosed with leukemia and is undergoing aggressive treatment to fight the disease.

Medical errors tend to occur more frequently at night and on weekends due to increased sleepiness, shortage of staff and a variety of other factors. Overall, such errors represent a significant problem for the medical community. A 1999 report from the Institute of Medicine showed that all medical errors -- including daytime errors, as well as night and weekend mistakes -- cause as many as 98,000 deaths each year and cost as much as $29 billion annually. Transplants are considered a source of concern by many experts because the surgeries occur when organs become available, and that is just as likely to be at an off-hour as during normal business hours.

In what is claimed to be the first operation of its kind, surgeons at Northwestern Memorial Hospital in Chicago have removed a transplanted kidney from its original recipient and implanted it in a second recipient. The kidney was failing in the first patient, but began fluorishing in the second and is now healthy. The first recipient of the kidney was Ray Fearing, a 27-year-old Arlington Heights, Ill., resident who suffers from focal segmental glomerulosclerosis (FSGS), in which scar tissue develops on the kidney and prevents the organ from filtering waste from the bloodstream.
