Argonne, Ill. (July 29, 2016) -- As scientists and policymakers around the world try to combat the increasing rate of climate change, they have focused on the chief culprit: carbon dioxide.
Produced by the burning of fossil fuels in power plants and car engines, carbon dioxide continues to accumulate in the atmosphere, warming the planet. But trees and other plants do slowly capture carbon dioxide from the atmosphere, converting it to sugars that store energy.
Washington, DC - July 29, 2016 - Many deadly diseases that afflict humans were originally acquired through contact with animals. New research published in ASM's Applied and Environmental Microbiology shows that pathogens can also jump the species barrier to move from humans to animals. The study, that will publish July 29, shows that green monkeys in The Gambia acquired Staphylococcus aureus from humans.
Researchers from Moscow Institute of Physics and Technology (MIPT), Skolkovo Institute of Science and Technology (Skoltech), the Technological Institute for Superhard and Novel Carbon Materials (TISNCM), the National University of Science and Technology MISiS (Russia), and Rice University (USA) used computer simulations to find how thin a slab of salt has to be in order for it to break up into graphene-like layers. Based on the computer simulation, they derived the equation for the number of layers in a crystal that will produce ultrathin films with applications in nanoelectronics.
OAK RIDGE, Tenn., July 29, 2016 - Climate and energy scientists at the Department of Energy's Oak Ridge National Laboratory have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise.
New research, using computer models of wave chaos, has shown that three-dimensional tangled vortex filaments can in fact be knotted in many highly complex ways.
The computer experiments, by academics at the University of Bristol, give rise to a huge variety of different knots, realising many that have been tabulated by pure mathematicians working in the field of knot theory.
MIAMI--A new study by an international team of scientists reveals the exact timing of the onset of the modern monsoon pattern in the Maldives 12.9 million years ago, and its connection to past climate changes and coral reefs in the region. The analysis of sediment cores provides direct physical evidence of the environmental conditions that sparked the monsoon conditions that exist today around the low-lying island nation and the Indian subcontinent.
Professors Chihiro Suzuki and Izumi Murakami's research group at the National Institute for Fusion Science, together with Professor Fumihiro Koike of Sophia University, injected various elements with high atomic numbers and produced highly charged ions(*1) in LHD plasmas. By measuring the emission spectrum of the extreme ultraviolet wavelength range, they discovered a new spectral line that had not been observed experimentally in the past.
Women enjoy a slight advantage over men when applying to become science teachers in France, a new study suggests. The results contrast with notions of a hiring bias against women in certain STEM fields, and may have implications for the debate over which interventions to pursue to increase the representation of women in science, technology, engineering, and mathematics. Discrimination against women during the hiring process is seen as one of the possible causes of their underrepresentation in fields including mathematics, physics and chemistry.
EUGENE, Ore. -- July 28, 2016 -- Deep down below us is a tug of war moving at less than the speed of growing fingernails. Keeping your balance is not a concern, but how the movement happens has been debated among geologists.
New findings from under the Pacific Northwest Coast by University of Oregon and University of Washington scientists now suggest a solution to a mystery that surfaced when the theory of plate tectonics arose: Do the plates move the mantle, or does the mantle move the plates.
While most farmers are actively trying to kill weeds, researchers in Ohio are trying to grow them - fast. Taraxacum kok-saghyz, a special variety of dandelion from Kazakhstan -- nicknamed "Buckeye Gold" by the researchers studying it -- may be the answer to sustainable and U.S.-based rubber-making. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, examines the plants' potential for revolutionizing the rubber industry.
Boulder, Colo., USA - Having been reported in lunar samples returned by Apollo astronauts, meteorites, impact glass, and at a number of meteorite craters on Earth, granular zircon is the most unusual and enigmatic type of zircon known. The mechanisms and transformations that form this distinctive granular zircon have, until now, remained speculative because it has not been produced in shock experiments.
Scientists of Tomsk State University are working on changing physicochemical properties of zeolites using thermal and mechanical treatment. Based on the results of this research the scientists will be able to create a new material for a portable device for hemodialysis.
The scientists examined synthetic zeolite powder manufactured by SAPO-34 and natural zeolite of Tokay deposits (Hungary)
Tropical Storm Georgette faded fast in the Eastern Pacific and NOAA's GOES-West satellite captured an image of the remnant clouds.
NOAA's GOES-West satellite captured a visible light image of the remnant clouds associated with former Tropical Storm Celia at 1715 UTC (1:15 p.m. EDT). The National Hurricane Center (NHC) issued their final advisory on the storm at 11 a.m. EDT when they noted that Georgette had become a remnant low pressure area.
In recent decades, the plight of Atlantic cod off the coast of New England has been front-page news. Since the 1980s in particular, the once-seemingly inexhaustible stocks of Gadus morhua -- one of the most important fisheries in North America -- have declined dramatically.
