New York | Heidelberg, 4 December 2014 Studying the motion of electrons in a disordered environment is no simple task. Often, understanding such effects requires a quantum simulator designed to expose them in a different physical setup. This was precisely the approach adopted by Denis Makarov and Leonid Kon'kov from the Victor I. Il'ichev Pacific Oceanological Institute in Vladivostok in a new study published in EPJ B. They relied on a simulator of electronic motion subjected to noise stemming from a flux of sound waves.

Wetlands are among the most productive ecosystems on Earth. Yet with increasing urbanization and agricultural expansion, wetlands around the globe are in danger. Better mapping of wetlands worldwide will help in their protection.
But compiling globe-spanning maps of wetlands is impeded by the dramatic diversity and evolving dynamics of wetlands, and by myriad difficulties in doing field work.
PULLMAN, Wash.--Washington State University researchers have detailed the role of localized climate change in one of the great mysteries of North American archaeology: the depopulation of southwest Colorado by ancestral Pueblo people in the late 1200s.
In the process, they address one of the mysteries of modern-day climate change: How will humans react?
HOUSTON - (Dec. 3, 2014) - Rice University scientists have discovered an environmentally friendly carbon-capture method that could be equally adept at drawing carbon dioxide emissions from industrial flue gases and natural gas wells.
The Rice lab of chemist Andrew Barron revealed in a proof-of-concept study that amine-rich compounds are highly effective at capturing the greenhouse gas when combined with carbon-60 molecules.
The research is the subject of an open-access paper today in Nature's online journal Scientific Reports.
A new time-lapse animation of data from NOAA's GOES-West satellite provides a good picture of why the U.S. West Coast continues to experience record rainfall. The new animation shows the movement of storms from Nov. 30 to Dec. 3.
NOAA's Geostationary Operational Environmental Satellites or GOES-West imagery from Nov. 30 to Dec. 3 was compiled into a 36 second video made by NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
DURHAM, N.C. -- Scientists have developed a way to sniff out tiny amounts of toxic gases -- a whiff of nerve gas, for example, or a hint of a chemical spill -- from up to one kilometer away.
The new technology can discriminate one type of gas from another with greater specificity than most remote sensors -- even in complex mixtures of similar chemicals -- and under normal atmospheric pressure, something that wasn't thought possible before.
Whether stubbing a toe or stroking a cat, the sensation of touch starts out as a mechanical force that is then transformed into an electrical signal conveying pain or other sensations. Tiny channels in neurons act as translators by helping to formulate that signal to the brain. However, scientists know little about the fine details of how these channels work.
A new research brief from the US2010 Project probes the status of minorities in American suburbs. Suburbs in 2010 were as racially and ethnically diverse as were central cities in 1980, and that diversity is still increasing. Yet minorities are not finding equal access to the American dream in the suburbs where they live, a lesson illustrated recently by Ferguson, MO.
New research shows that ocean heat uptake across three oceans is the likely cause of the 'warming hiatus' - the current decade-long slowdown in global surface warming.
Using data from a range of state-of-the-art ocean and atmosphere models, the research shows that the increased oceanic heat drawdown in the equatorial Pacific, North Atlantic and Southern Ocean basins has played a significant role in the hiatus.
WASHINGTON, D.C., December 3, 2014--A new report from the American Institute of Physics (AIP) Statistical Research Center has found that the number of Hispanic students receiving bachelor's degrees in the physical sciences and engineering has increased over the last decade or so, passing 10,000 degrees per year for the first time in 2012. The overall number of U.S. students receiving degrees in those fields also increased over the same time, but it increased faster among Hispanics.
Humans have been experimenting with and utilizing glassy materials for more than ten millennia, dating back to about 12000 B.C. Although glassy materials are the oldest known artificial materials, new discoveries and novel applications continue to appear.
Yet understanding of glass is far from complete, and the nature of glass constitutes a longstanding puzzle in condensed mater physics.
A glimmer of hope for corals as baby reef builders cope with acidifying oceans
While the threat of coral bleaching as a result of climate change poses a serious risk to the future of coral reefs worldwide, new research has found that some baby corals may be able to cope with the negative effects of ocean acidification.
Ocean acidification, which is a direct consequence of increased atmospheric carbon dioxide levels, is expected to have a deleterious effect on many marine species over the next century.

It takes just 10 years for a single emission of carbon dioxide (CO2) to have its maximum warming effects on the Earth.
This is according to researchers at the Carnegie Institute for Science who have dispelled a common misconception that the main warming effects from a CO2 emission will not be felt for several decades.
Washington, D.C.--The climate warming caused by a single carbon emission takes only about 10 years to reach its maximum effect. This is important because it refutes the common misconception that today's emissions won't be felt for decades and that they are a problem for future generations.
For the first time, a study conducted by Carnegie's Katharine Ricke and Ken Caldeira has evaluated how long it takes to feel the maximum warming effect caused by a single carbon emission. Their work is published in Environmental Research Letters.
