U.S. patent agency to decide inventor of powerful gene editing technology

By Andrew Chung NEW YORK (Reuters) - A showdown between two teams of top U.S. scientists over who was first to invent a breakthrough gene-editing technology known as CRISPR formally began on Monday as a U.S. government agency launched proceedings to decide the issue. The outcome could be worth hundreds of millions of dollars as scientists say the powerful technology allows for easier and more precise genetic engineering in living cells. A tribunal within the U.S. Patent and Trademark Office, which initiated the proceeding known as an interference, will now examine both sides' evidence, a process that could take months, to determine who should own a patent on the technology.

Task Force Issues New Breast Cancer Screening Recommendations

Women who have an average risk of breast cancer should have mammograms every two years from ages 50 to 74, according to the latest recommendations released today by the U.S. Preventive Services Task Force (USPSTF). Average-risk women in their 40s also may benefit from getting mammograms, but their overall likelihood of seeing a benefit is smaller, and the potential for harm is larger than for average-risk women age 50 and older, according to the USPSTF's recommendations, published online today (Jan. 11) in the journal Annals of Internal Medicine.

Gulp. Sugary Drinks Linked to 'Deep' Fat

People who drink sugary beverages, such as soda or fruit juice, daily tend to gain a type of body fat associated with diabetes and heart disease, a new study finds. Researchers looked at about 1,000 middle-age people over a six-year period and found that those who drank sugar-sweetened beverages tended to have more "deep," or visceral, fat. Previous research has linked sweet drinks with other health risks.

Prosthetic Leg with Hoofed Foot Discovered in Ancient Chinese Tomb

The 2,200-year-old remains of a man with a deformed knee attached to a prosthetic leg tipped with a horse hoof have been discovered in a tomb in an ancient cemetery near Turpan, China. "The excavators soon came to find that the left leg of the male occupant is deformed, with the patella, femur and tibia [fused] together and fixed at 80 [degrees]," archaeologists wrote in a paper published recently in the journal Chinese Archaeology. The man couldn't straighten his left leg out so the prosthetic leg, when attached, allowed the left leg to touch the floor when walking.

Archaeologists hail find of 'best-preserved' UK Bronze Age dwellings

Archaeologists said on Tuesday they had discovered what were believed to be the best-preserved Bronze Age dwellings ever found in Britain, providing an extraordinary insight into prehistoric life from 3,000 years ago. The settlement of large circular wooden houses, built on stilts, collapsed in a fire and plunged into a river where it was preserved in silts leaving them in pristine condition, Historic England said. Discoveries from the dwellings in Whittlesey, in central England, which archaeologists said had been frozen in time and dated from between 1000-800 BC, included pots with food inside and finely woven clothing.
