New studies show impact of BP's Deepwater Horizon disaster on dolphins and other marine wildlife may be far worse than feared.

A new study of dolphins living close to the site of North America's worst ever oil spill – the BP Deepwater Horizon catastrophe two years ago – has established serious health problems afflicting the marine mammals.

The report, commissioned by the National Oceanic and Atmospheric Administration [NOAA], found that many of the 32 dolphins studied were underweight, anaemic and suffering from lung and liver disease, while nearly half had low levels of a hormone that helps the mammals deal with stress as well as regulating their metabolism and immune systems.

EAST LANSING, Mich. — Researchers at Michigan State University have unraveled the mystery of how microbes generate electricity while cleaning up nuclear waste and other toxic metals.

Details of the process, which can be improved and patented, are published in the current issue of the Proceedings of the National Academy of Sciences. The implications could eventually benefit sites forever changed by nuclear contamination, said Gemma Reguera, MSU microbiologist.

“Geobacter bacteria are tiny micro-organisms that can play a major role in cleaning up polluted sites around the world,” said Reguera, who is an MSU AgBioResearch scientist. “Uranium contamination can be produced at any step in the production of nuclear fuel, and this process safely prevents its mobility and the hazard for exposure.”

MOBILE, Alabama -- Oil is once again fouling the Gulf of Mexico around the Deepwater Horizon well, which was capped a little over a year ago.

Tuesday afternoon, hundreds of small, circular patches of oily sheen dotted the surface within a mile of the wellhead. With just a bare sheen present over about a quarter-mile, the scene was a far cry from the massive slick that covered the Gulf last summer.

Floating in a boat near the well site, Press-Register reporters watched blobs of oil rise to the surface and bloom into iridescent yellow patches. Those patches quickly expanded into rainbow sheens 4 to 5 feet across.

Each expanding bloom released a pronounced and pungent petroleum smell. Most of the oil was located in a patch about 50 yards wide and a quarter of a mile long.
