Workers took the Keystone oil pipeline offline on Thursday after it spilled 5,000 barrels of oil in rural South Dakota, officials said.
A TransCanada crew shut down the pipeline at 6 a.m. Thursday morning after detecting an oil leak along the line, the company said. The leak was detected along a stretch of the pipeline about 35 miles south of a pumping station in Marshall County, South Dakota.
TransCanada estimates the pipeline leaked 5,000 barrels of oil, or about 210,000 gallons, before going offline. The company said it's working with state regulators and the Pipelines and Hazardous Materials Safety Administration to assess the situation. read more

John Hillerman, a Texas-born actor best remembered as the stuffy English foil Higgins to Tom Selleck's freewheeling private detective on the hit 1980s television series "Magnum, P.I.," died Nov. 9 at his home in Houston. He was 84. A spokeswoman, Lori De Waal, said the cause of death has yet to be determined. Hillerman was a theater stalwart and versatile Hollywood character actor before becoming a household name as Jonathan Quayle Higgins III on Magnum, P.I., which aired on CBS from 1980 to 1988. read more
Australian researchers have identified a significant link between a gene involved in testosterone action and male-to-female transsexualism.
DNA analysis from 112 male-to-female transsexual volunteers showed they were more likely to have a longer version of the androgen receptor gene.
The genetic difference may cause weaker testosterone signals, the team reported in Biological Psychiatry.
However, other genes are also likely to play a part, they stressed.
Increasingly, biological factors are being implicated in gender identity.
