Scientists have found that even second-hand tobacco smoke exposure can result in nonalcoholic fatty liver disease, a common disease in which fat accumulates in the liver of people who drink little or no alcohol. The researchers found fat accumulated in liver cells of mice exposed to second-hand cigarette smoke for a year in the lab. [...]

‘Watchful Waiting’ Is A Viable Option For Prostate Cancer Patients With Low-risk Tumors, Study Finds
Appropriately selected prostate cancer patients, including older men and men with small, low-risk tumors, may safely defer treatment for many years with no adverse consequences, according to a new study.
The link between declining carbon dioxide levels in the earth’s atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

A giant African lake basin is providing information about possible migration routes and hunting practices of early humans in the Middle and Late Stone Age periods, between 150,000 and 10,000 years ago. Researchers have documented thousands of stone tools on the lake bed, which sheds new light on how humans in Africa adapted to several [...]
