The deepest layers of carbon-14 dated ice found in the Col du Dôme of the Mont Blanc glacier in the French Alps provide a record of atmospheric conditions in the ancient Roman era.
A study from The University of Texas at Austin is the first published in a scientific journal to take an in-depth look at the challenging geologic conditions faced by the crew of the Deepwater Horizon drilling rig and the role those conditions played in the 2010 disaster.
The feedback between a warming climate and accelerated release of carbon currently frozen into permafrost around the Arctic is one of the grand challenges in current climate research. A study published this week in the Proceedings of the National Academy of Sciences of the USA by a team of researchers led by Stockholm University used radiocarbon dating of carbon in four large Siberian-Arctic rivers to pinpoint the patterns of old carbon release from permafrost across northern Eurasia.
The Tibetan Plateau, as Earth's "Third Pole," was reported to be first occupied by modern humans probably armed with blade technology as early as 40 ka BP. However, no earlier hominin groups had been found or reported on the Tibetan Plateau until a recent study was published by Chinese researchers.
UNIVERSITY PARK, Pa. -- A thousand years ago, Native Americans in South America used multiple psychotropic plants -- possibly simultaneously -- to induce hallucinations and altered consciousness, according to an international team of anthropologists.
Melbourne: Australian scientists have developed an innovative method using cores drilled from coral to produce a world first 400-year long seasonal record of El Niño events, a record that many in the field had described as impossible to extract.
In a paper to be published in the forthcoming issue in NANO, a team of researchers has reviewed the methods of synthesizing copper nanowires (Cu NWs) and techniques to improve its oxidation resistance.
Matter waves constitute a crucial feature of quantum mechanics, where particles have wave properties in addition to particle characteristics. This wave-particle duality was postulated already in 1924 by the French physicist Louis de Broglie.
Forest fires are causing snow to melt earlier in the season, a trend occurring across the western U.S. that may affect water supplies and trigger even more fires, according to a new study by a team of researchers at Portland State University (PSU) , the Desert Research Institute (DRI), and the University of Nevada, Reno.
The combination of a big population, good genes, and luck help explain how a species of fish in Texas' Houston Ship Channel was able to adapt to what normally would be lethal levels of toxins for most other species, according to a study to be published May 3 in the journal Science.
In an unusual new study, scientists say they have detected the fingerprint of human-driven global warming on patterns of drought and moisture across the world as far back as 1900. Rising temperatures are well documented back at least that far, but this is the first time researchers have identified resulting long-term global effects on the water supplies that feed crops and cities.
A "sleeping giant" hidden in permafrost soils in Canada and other northern regions worldwide will have important consequences for global warming, says a new report led by University of Guelph scientist Merritt Turetsky.
An international team of scientists has found part of the world's largest ice shelf is melting 10 times faster than the overall ice shelf average, due to solar heating of the surrounding ocean surface.
When the landmass that is now the Indian subcontinent slammed into Asia about 50 million years ago, the collision changed the configuration of the continents, the landscape, global climate and more. Now a team of Princeton University scientists has identified one more effect: the oxygen in the world's oceans increased, altering the conditions for life.
Scientists from the National University of Science and Technology "MISIS" together with their colleagues from Derzhavin Tambov State University and Saratov Chernyshevsky State University have figured out that graphene is capable of purifying water, making it drinkable, without further chlorination. "Capturing" bacterial cells, it forms flakes that can be easily extracted from the water. Graphene separated by ultrasound can be reused.
