Researchers have published their most advanced calculation for the likely impact of melting ice on global sea levels.
The EU-funded team says the ice sheets and glaciers could add 36.8cm to the oceans by 2100.
Adding in other factors, sea levels could rise by up to 69cm, higher than previous predictions.
Earth's global thaw has reached Mount Everest, the world's tallest peak, researchers said Tuesday at the Meeting of the Americas in Cancun, Mexico.
Glaciers in the Mount Everest region have shrunk by 13 percent in the last 50 years and the snowline has shifted upward by 590 feet, Sudeep Thakuri, a graduate student at the University of Milan in Italy, said in a statement. Located in the Himalaya Mountains on the border between China and Nepal, Everest's summit is 29,029 feet above sea level.
The best way to feed the 9 billion people expected to be alive by 2050 could be to rear billions of common houseflies on a diet of human faeces and abattoir blood and grind them up to use as animal feed, a UN report published on Monday suggests. Doing so would reduce the pressure on the Earth's forests and seas as food sources.
Northwestern University scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch -- instead of cyanide -- to isolate gold from raw materials in a selective manner.
This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold. The new process also can be used to extract gold from consumer electronic waste.
Supporters of Nikola Tesla, who lighted the planet with alternating current but died penniless, announced on Thursday that they had completed the purchase of his decaying laboratory on Long Island and begun raising $10 million for its restoration and the establishment of a museum and educational memorial.
In the pitched debate over genetically modified (GM) foods and crops, it can be hard to see where scientific evidence ends and dogma and speculation begin. In the nearly 20 years since they were first commercialized, GM crop technologies have seen dramatic uptake. Advocates say that they have increased agricultural production by more than US$98 billion and saved an estimated 473 million kilograms of pesticides from being sprayed. But critics question their environmental, social and economic impacts.
Pope Celestine V was an elderly, possibly frail man. After living as a self-flagellating hermit in Italy, he served as pontiff for only five months before resigning at the end of the 13th century. Since his death, the so-called "Hermit Pope" has been the subject of much speculation and intrigue, with legend holding that the he was murdered by his successor, Boniface VIII.
Human cloning has been used to produce early embryos, marking a "significant step" for medicine, say US scientists.
In news that’s sure to delight young boys everywhere, scientists now have a better grasp on the impressive winds of Uranus. Neptune too. In a Nature study published today astronomers find that the most obvious weather patterns on the two ice giants are relatively shallow, only about 1,100 kilometers (683 miles) deep at most. The finding helps researchers understand the internal dynamics on Uranus, Neptune and similar exoplanets.
The central principle of quantum mechanics--that the act of measuring a quantum object actually changes it--has some pretty amazing potential in the world of cryptography. And Los Alamos National Laboratory just revealed that it has been using a new design of quantum cryptography setup for more than two years.
When some future Mars colonist is able to open his browser and watch a cat in a shark suit chasing a duck while riding a roomba, they will have Vint Cerf to thank.
In his role as Google’s chief internet evangelist, Cerf has spent much of his time thinking about the future of the computer networks that connect us all. And he should know. Along with Bob Kahn, he was responsible for developing the internet protocol suite, commonly known as TCP/IP, that underlies the workings of the net. Not content with just being a founding father of the internet on this planet, Cerf has spent years taking the world wide web out of this world.
Einstein's special relativity has proven more useful than ever, as scientists have now used it to discover an alien planet around another star.
The newfound world — nicknamed "Einstein's planet" by the astronomers who discovered it — is the latest of more than 800 planets known to exist beyond our solar system, and the first to be found through this method.
Astronomers are closer than ever to finding a true alien Earth, though the process may be slowed by budget cuts, scientists told members of Congress late last week.
Officials from NASA, the National Science Foundation and the SETI (Search for Extraterrestrial Intelligence) Institute gave testimony to the House Science, Space and Technology Committee on Thursday about the state of exoplanet research, saying researchers were closing in on planets around other stars that are the same size and distance from their suns as Earth.
American astronauts could be forced to fly on Russian spacecraft beyond 2017 if Congress continues to cut funding for private crewed vehicles, NASA chief Charles Bolden says.
On Tuesday (April 30), NASA announced that it will pay $70.7 million each for six more seats aboard Russian Soyuz space capsules. The $424 million deal keeps Americans launching to the International Space Station aboard the Soyuz through 2016, with return and rescue services extending until June 2017.
"Why are people so fascinated with @Cmdr_Hadfield?" the tweeter asked. "Can someone enlighten me?"
he Canadian astronaut who became a music sensation when his zero-gravity version of David Bowie's "Space Oddity" went viral on the web returned to Earth along with two crewmates on Tuesday after a five-month stint on the International Space Station.
When the British archaeologist Sir Arthur Evans discovered the 4,000-year-old Palace of Minos on Crete in 1900, he saw the vestiges of a long-lost civilization whose artefacts set it apart from later Bronze-Age Greeks. The Minoans, as Evans named them, were refugees from Northern Egypt who had been expelled by invaders from the South about 5,000 years ago, he claimed.
The bond between dogs and humans is ancient and enduring. They snuggle up to us at night, gambol by our side during daily walks, and flop adoringly at our feet when we crash on our couches. But new research shows that the connection runs deeper than you might think. It is embedded in our genes.
Citizen scientists, environmentalists and anyone who lives near a power plant -- your services are requested. Climate change scientist Kevin Robert Gurney needs your help in a grand undertaking: the mapping of all the power plants in the world.
It's a big job, and he and the people in his lab cannot do it alone.
A WORLD-RENOWNED archaeologist has warned that people should be concerned about the issue of resurrecting extinct species.
