Gas giants: Can we stop cows from emitting so much methane?
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.
Sinkholes on receding Dead Sea shore mark 'nature's revenge'
That cow may look peaceful and harmless, munching on some grass in a verdant pasture.
Greenpeace urges Europe to drop short flights, take trains
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.
Finnish scientists create 'sustainable' lab-grown coffee
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.
Orkney's seaweed-eating sheep offer hopes of greener farming
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.
Kiwi boffins aim to clear the air on livestock emissions
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.
'Save your species': UN uses dinosaur in fossil fuel message
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.
Study confirms mistaken identity may explain why sharks bite humans
The United Nations is summoning an unusual "witness" to testify to the dangers of burning fossil fuels that stoke global warming: a dinosaur.
Fossil dental exams reveal how tusks first evolved
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.
Searching for Earth 2.0? Zoom in on a star
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...
How do plants act fast to fight off infections?
Astronomers searching for Earth-like planets in other solar systems have made a breakthrough by taking a closer look at the surface of stars.
A new 3D printing frontier: Self-powered wearable devices
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.

This device could usher in GPS-free navigation
Study reveals a gene crucial to sperm cell production
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.
Scientists at Cincinnati Children's appear to have flipped another piece in the underexplored puzzle of male infertility.
