Researchers found a plant deposit this year, revealed when the margin of the Quelccaya Ice Cap retreated. It was the second such find in the last two years.
The latest expeditions to ice caps in the high, tropical Peruvian Andes Mountains by Ohio State University scientists may shed light on a mysterious global climate change they believe occurred more than 5,000 years ago.
They hope that ice cores retrieved from two tropical ice caps there, as well as ancient plants retrieved from beneath the retreating glaciers, may contain clues that could link ancient events that changed daily life in South America, Europe and Asia.
Something happened 5,200 years ago that was abrupt and very large-scale, explained Lonnie Thompson, professor of geological sciences at Ohio State and researcher with the Byrd Polar Research Center.

New findings on the largest natural sulfur source in the atmosphere

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.
With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.
Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...
