Water's reaction with metal oxides opens doors for researchers
Madison WI (SPX) Aug 11, 2014 -
A multi-institutional team has resolved a long-unanswered question about how two of the world's most common substances interact.
In a paper published recently in the journal Nature Communications, Manos Mavrikakis, professor of chemical and biological engineering at the University of Wisconsin-Madison, and his collaborators report fundamental discoveries about how water reacts with metal o ...

Sulfur signals in Antarctic snow reveal clues to climate, past and future
San Diego CA (SPX) Aug 06, 2014 -
Sulfur signals in the Antarctic snow have revealed the importance of overlooked atmospheric chemistry for understanding climate, past and future.
Eruptions of huge volcanoes, the disruptive weather pattern known as El Nino, and a fire season from hell each left distinctive chemical marks in layers of snow excavated near the South Pole, researchers from the University of California, San Die ...

Trapped atmospheric waves triggered more weather extremes
Potsdam, Germany (SPX) Aug 12, 2014 -
It has been linked to a recently discovered mechanism: the trapping of giant waves in the atmosphere. A new data analysis now shows that such wave-trapping events are indeed on the rise.
"The large number of recent high-impact extreme weather events has struck and puzzled us," says Dim Coumou, lead author of the study conducted by a team of scientists from the Potsdam Institute for Climate ...

NIST ion duet offers tunable module for quantum simulator
Boulder CO (SPX) Aug 07, 2014 -
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a pas de deux of atomic ions that combines the fine choreography of dance with precise individual control.
NIST's ion duet, described in Nature, is a component for a flexible quantum simulator that could be scaled up in size and configured to model quantum systems of a complexity that overwhelms tradi ...

Study finds physical link to strange electronic behavior
Houston TX (SPX) Aug 05, 2014 -
Scientists have new clues this week about one of the baffling electronic properties of the iron-based high-temperature superconductor barium iron nickel arsenide.
A Rice University-led team of U.S., German and Chinese physicists has published the first evidence, based on sophisticated neutron measurements, of a link between magnetic properties and the material's tendency, at sufficiently l ...

Hubble Revisits a Globular Cluster's Age
Washington DC (SPX) Aug 15, 2014 -
This new NASA/ESA Hubble Space Telescope image shows the globular cluster IC 4499. Globular clusters are big balls of old stars that orbit around their host galaxy.
It has long been believed that all the stars within a globular cluster form at the about same time, a property which can be used to determine the cluster's age.
For more massive globulars however, detailed observations ha ...
