A Virginia Tech research team has developed a battery that runs on sugar and has an unmatched energy density, a development that could replace conventional batteries with ones that are cheaper, refillable, and biodegradable.
New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied at the Faculty of Physics at the University of Warsaw. The materials and elements used to form these structures allow us forecast new trends in solotronics – a field of experimental electronics and spintronics of the future, based on operations occurring on a single-atom level.
Researchers from Brown University have shown experimentally that a boron-based competitor to graphene is a very real possibility. Graphene has been heralded as a wonder material. Made of a single layer of carbon atoms in a honeycomb arrangement, graphene is stronger pound-for-pound than steel and conducts electricity better than copper.
Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth’s oceans to the upper mantle than previously thought.
Why did life forms first begin to get larger and what advantage did this increase in size provide? UCLA biologists working with an international team of scientists examined the earliest communities of large multicellular organisms in the fossil record to help answer this question.
The gradual warming of the North and tropical Atlantic Ocean is contributing to climate change in Antarctica, a team of New York University (NYU) scientists supported by the National Science Foundation (NSF) has concluded. Their findings appear in the Jan. 23 edition of the journal Nature.
Suck it, white supremacists! The genome of a 7,000-year-old individual from the Mesolithic site of La Brana-Arintero (Leon, Spain) has been recovered and it has African versions in the genes that determine pigmentatio of the skin.
Stephen Hawking, the 70 year old greatest living physicist of the universe, has identified his biggest mistake. Only Hawking can get away with saying that, strictly speaking, there are no black holes in our universe.
Bremerhaven/Germany, 24 January 2014. In spring 2010, the research icebreaker Polarstern returned from the South Pacific with a scientific treasure - ocean sediments from a previously almost unexplored part of the South Polar Sea.
Geoscientist Erik Lundin shows in his thesis that streams and lakes of Northern Sweden are hotspots for emissions of carbon dioxide and methane into the atmosphere.
“Cool it!” That’s a prime directive for microprocessor chips and a promising new solution to meeting this imperative is in the offing. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a “process friendly” technique that would enable the cooling of microprocessor chips through carbon nanotubes.
Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic clock that has set new world records for both precision and stability-- key metrics for the performance of a clock.
Chinese air pollution blowing across the Pacific Ocean is often caused by the manufacturing of goods for export to the U.S. and Europe, according to findings by UC Irvine and other researchers published earlier this week in the Proceedings of the National Academy of Sciences.
Transparent displays have a variety of potential applications — such as the ability to see navigation or dashboard information while looking through the windshield of a car or plane, or to project video onto a window or a pair of eyeglasses. A number of technologies have been developed for such displays, but all have limitations.
NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.
When the temperature rises on Baffin Island, in the Canadian high Arctic, ancient Polytrichum mosses, trapped beneath the ice for thousands of years, are exposed. Using radiocarbon dating, new research in Geophysical Research Letters has calculated the age of relic moss samples that have been exposed by modern Arctic warming.
JoVE, the Journal of Visualized Experiments, publishes a modern approach to a famed experiment that explored one of the most intriguing research questions facing scientists today—the origin of life on earth.
Until recently, measuring a 27-dimensional quantum state would have been a time-consuming, multistage process using a technique called quantum tomography, which is similar to creating a 3D image from many 2D ones.
The alien world of aquatic micro-organisms just got new residents: synthetic self-propelled swimming bio-bots.
Extreme weather events fuelled by unusually strong El Ninos, such as the 1983 heatwave that led to the Ash Wednesday bushfires in Australia, are likely to double in number as our planet warms.
