Baltimore, Feb 5 : Michael Phelps has confessed that he's embarrassed by the marijuana incident, and is weighing whether to take part in 2012 Olympics.

The pics published in Britain''s News of the World, showing the eight times Olympic gold medallist using a bong, were taken in November at a University of South Carolina house party.

The 23-year-old star admits that he "clearly made a mistake," and the past week has been both embarrassing and uncomfortable for him.

BALTIMORE, Nov. 28 - U. S. researchers say they have discovered a novel pathway for potential human exposure to antibiotic-resistant bacteria from poultry trucks.

Researchers at The Johns Hopkins University Bloomberg School of Public Health in Baltimore say broiler chickens typically are transported in open crates on the back of flatbed trucks with no effective barrier to prevent release of pathogens into the environment. These crates become contaminated with feces and bacteria.
