We summarize the week's scientific breakthroughs every Thursday.
- Oceans
Deepwater Horizon methane lingered longer than thought
Microbes may not have consumed methane from the 2010 Deepwater Horizon oil spill as fast as previously thought.
- Climate
Antarctic glacier melt is unstoppable
The inevitable collapse of Antarctic’s western glaciers could raise global sea level by more than 4 meters in coming centuries.
- Climate
Tropics leave trace in Arctic warming
Cooling temperatures in the Pacific may be responsible for the recent rapid warming of northeastern Canada and Greenland.
- Environment
BP oil spill may have killed hundreds of thousands of birds
The 2010 Deepwater Horizon oil spill may have killed 600,000 to 800,000 coastal birds, new simulations suggest.
- Climate
Crop nutrients may drop as carbon dioxide rises
Many staple grains and legumes pack 5 to 10 percent less iron, zinc and protein when grown at carbon dioxide levels expected midcentury.
- Climate
Federal report details climate change in U.S.
The latest National Climate Assessment was released by federal officials May 6.

Some birds adapt to Chernobyl’s radiation
Some birds seem to fare well in and near the Chernobyl exclusion zone, but overall the nuclear disaster has been bad news for the region’s bird populations.
- Environment
Prestige oil spill linked to drop in seabird chicks
European shag in colonies affected by the 2002 Prestige oil tanker spill produced fewer chicks than birds in oil-free colonies.
- Climate
Glacial microbes gobble methane
While some bacteria produce methane in Greenland’s melting ice sheet, others may consume the greenhouse gas as it escapes.
- Animals
Secrets of a sailfish attack
The large, long-nosed sailfish use their rostrums more like a sword than a spear to attack prey.
- Environment
Lead levels in ancient Rome’s water were high, but not toxic
Ancient Romans probably drank tap water with up to 100 times more lead than the levels found in local spring water.
