Research overturns assumption about mercury in the Arctic
For years, scientists have assumed that if mercury is high and increasing in fish in the North American and European Arctic, the same is true of fish elsewhere in the Arctic.
'Superbugs' found breeding in sewage plants

Flame retardants in blood drop after state ban
A class of flame retardants that has been linked to learning difficulties in children has rapidly declined in pregnant women's blood since the chemicals were banned in California a decade ago, according to a study led by ...
Scientists relate urban population to air pollution
(Phys.org) —Live in a large city like New York, London, Beijing or Mumbai, and you are likely exposed to more air pollution than people in smaller cities in surrounding areas. But exactly how a city's pollution ...
Stanford researchers say 'peak oil' concerns should ease
Fears of depleting the Earth's supply of oil are unwarranted, according to new research, which concludes that the demand for oil – as opposed to the supply – will reach its own peak and then decline.
