Surf And Turf: To Reduce Gas Emissions From Cows, Scientists Look To The Ocean
When cows burp, they emit the potent greenhouse gas methane into the atmosphere. But by adding seaweed to the cows' diets, researchers are noticing a dramatic reduction in methane production.
Large Methane Leaks Threaten Perception Of 'Clean' Natural Gas
A new study finds that oil and gas operations are leaking 60 percent more methane than previously reported by the federal government.
NASA's Curiosity Rover Finds Chemical Building Blocks For Life On Mars
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.
Mysteries of the Moo-crobiome: Could Tweaking Cow Gut Bugs Improve Beef?
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.
Gassy Cows Warm The Planet. Scientists Think They Know How To Squelch Those Belches
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.
Appeals Court Says EPA Can't Keep Delaying Obama-Era Methane Rules
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.
Senators Reject Effort To Roll Back Greenhouse Gas Emissions Rule
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.
Inside The Debate Over Repealing Curbs On Methane Leaks
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.
Methane's On The Rise, But Regulations To Stop Gas Leaks Still Debated
Scientists concede that oil and gas production is only partly to blame for the 3 percent surge in the greenhouse gas in the last decade. Obama tightened rules on the industry. Will Trump repeal them?
