The contribution of particulate matter to forest decline
Air pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles. Bonn University scientists have now discovered a responsible mechanism: particulate matter ...
Scientists make first direct images of topological insulator's edge currents
(Phys.org) —Researchers at a SLAC/Stanford institute have made the first direct images of electrical currents flowing along the edges of a topological insulator – a recently discovered state of matter ...
NASA image: Pyrocumulus cloud billows from New Mexico fire
On June 12, 2013, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this image of the Silver fire burning east of Silver City, New Mexico. In addition to producing ...
China seen facing uphill struggle against pollution
China's newly announced measures to combat pollution by slashing emissions from major polluting industries and holding local officials responsible could take 18 years to bring air quality within acceptable standards, analysts ...
China to hold local leaders responsible for air quality
China has pledged to hold local government leaders responsible for improving air quality, officials said, after heavy smog across China earlier this year stoked social discontent.
Observation of magnetic flipping in single proton heralds high-precision studies into matter and antimatter
One of the greatest mysteries of modern physics is the imbalance of matter and antimatter in the Universe. As every particle is produced and destroyed in tandem with its antiparticle, which has an identical ...
Cosmic giants shed new light on dark matter
(Phys.org) —Astronomers at the University of Birmingham (UK), Academica Sinica in Taiwan, and the Kavli Institute of Physics and Mathematics of the Universe in Japan, have found new evidence that the mysterious ...
A video map of motions in the nearby universe
(Phys.org) —An international team of researchers, including University of Hawaii at Manoa astronomer Brent Tully, has mapped the motions of structures of the nearby universe in greater detail than ever ...
Persistence of 'urban' organics downstream favors dead-zone formation
(Phys.org) —Each time it rains, runoff carries an earthy tea steeped from leaf litter, crop residue, soil, and other organic materials into the storm drains and streams that feed Chesapeake Bay.
Tillage and reduced-input rotations affect runoff from agricultural fields
No-till management practices can reduce soil erosion, but evidence suggests they can also lead to increased runoff of dissolved phosphorus from soil surfaces. Meanwhile, farmers looking to avoid herbicides ...
Euclid to probe dark Universe with Astrium science module
(Phys.org) —The module carrying the telescope and scientific instruments of ESA's Euclid 'dark Universe' mission is now being developed by Astrium in Toulouse, France.
Physicists show self-correcting quantum computers are theoretically possible
Simple theory may explain dark matter
Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole.
Scientists size up universe's most lightweight dwarf galaxy
(Phys.org) —The least massive galaxy in the known universe has been measured by UC Irvine scientists, clocking in at just 1,000 or so stars with a bit of dark matter holding them together.
