"This would be a huge step backward," said one environmental advocate. "It would cause greatly increased pollution." The Trump administration says it will help the oil and gas industry save money.

Cottonwood trees can harbor microorganisms that have a special (and flammable) characteristic.

A new study finds that oil and gas operations are leaking 60 percent more methane than previously reported by the federal government.

Scientists can't say whether there is, or ever was, life on the Red Planet. But two Martian rock samples contained organic molecules — which contain carbon, the chemical element central to life.

Microbe-free bovine life would be rough. Cows rely on single-cell accomplices for their digestion, so scientists are looking for ways to use these bugs to improve cows' eating and burping habits.

Researchers have won a prize for discovering that a cow's genetics determine which microbes populate its gut. Some of those microbes produce the greenhouse gas methane that ends up in the atmosphere.

The U.S. Court of Appeals for D.C. notes the EPA can choose to rewrite a rule designed to prevent leaks from natural gas facilities. But it can't just put it off for two years, the judges decided.

It's a rare victory for environmentalists so far under President Trump. The Senate rejection to rolling back an Obama-era regulation was close — tipping after three Republican senators voted no.

A deadline is approaching for lawmakers to undo an Obama-era regulation that aims to limit the emissions of methane — a powerful greenhouse gas — from energy production sites on public lands.
