A yellow streak representing high concentrations of methane, a dangerous greenhouse gas, is visible over southern Iraq on a map produced by Kayrros, a French firm that uses satellites to track leaks from fossil fuel facilities.

That cow may look peaceful and harmless, munching on some grass in a verdant pasture.

In the heyday of the Ein Gedi spa in the 1960s, holidaymakers could marinate in heated pools and then slip into the briny Dead Sea. Now the same beach is punctured by craters.

A study commissioned by the environmental group Greenpeace shows that over one-third of the busiest short-haul flights in Europe have viable train alternatives which are far less polluting.

Latte drinkers may in the future be sipping on java sourced from a petri dish rather than a plantation, say scientists behind a new technique to grow what they hope to be sustainable coffee in a lab.

On a tiny island in Scotland's far-flung Orkneys, thousands of sheep spend the winter munching on seaweed, a unique diet that scientists say offers hope for reducing planet-warming methane emissions.

Tucked away in rural New Zealand, a multi-million dollar research facility is working to slash the greenhouse gases released into the atmosphere by farm animals—saving the world one belch at a time.

The United Nations is summoning an unusual "witness" to testify to the dangers of burning fossil fuels that stoke global warming: a dinosaur.

World-first research testing a simulated 'shark vision' model on swimming patterns of humans, seals and sea-lions, confirms theories that when great white sharks bite humans, it may be a case of mistaken identity.

A wide variety of animals have tusks, from elephants and walruses to five-pound, guinea pig-looking critters called hyraxes. But one thing tusked animals have in common is that they're all mammals—there are no known fish, reptiles, or birds with tusks. In a new study in Proceedings of the Royal Society B, paleontologists traced the first tusks back to ancient mammal relatives that lived before...

Astronomers searching for Earth-like planets in other solar systems have made a breakthrough by taking a closer look at the surface of stars.

New work led by Carnegie's Kangmei Zhao and Sue Rhee reveals a new mechanism by which plants are able to rapidly activate defenses against bacterial infections. This understanding could inspire efforts to improve crop yields and combat global hunger.

When most people think of wearable devices, they think of smart watches, smart glasses, fitness trackers, even smart clothing. These devices, part of a fast-growing market, have two things in common: They all need an external power source, and they all require exacting manufacturing processes. Until now.

Don't let the titanium metal walls or the sapphire windows fool you. It's what's on the inside of this small, curious device that could someday kick off a new era of navigation.
