More CO2 won’t help northern forests or stave off climate change

Study using tree ring data and climate projections shows that buildup of CO2 will not benefit most northern forests and that growth rates will actually fall.

Can we harness bacteria to help clean up future oil spills?

Genetic analysis shows that marine bacteria broke down much of the oil from the 2010 Deepwater Horizon spill. These findings could lead to more effective cleanups after future spills.

Of bears and biases: scientific judgment and the fate of Yellowstone’s grizzlies

The grizzly bear of Yellowstone is expected to be delisted from the Endangered Species Act. But a survey of grizzly bear researchers finds flaws in how wildlife experts evaluate scientific data.
