'Incoherent excitations' govern key phase of superconductor behavior: UBC research

New research by University of British Columbia physicists indicates that high-temperature superconductivity in copper oxides is linked to what they term 'incoherent excitations'--a discovery that sheds light on the electronic response of these materials before they become superconducting.

The study marks the first time researchers have been able to directly measure when electrons in a super conductor behave as independent well-defined particles, and when they evolve into ill-defined many-body entities.

UT Dallas researcher helps reveal more complete picture of Martian atmosphere

Instruments designed by a UT Dallas professor to measure atmospheric components on the surface of Mars have uncovered important clues about the planet's atmosphere and climate history.

The findings, published in a recent issue of the journal Science, reveal how carbon dioxide isotopes have reacted to volcanic activity, water and weathering – thus forming a more complete picture of the current Martian atmosphere.

The NASA mission in which this work was accomplished was the Phoenix Lander, an unmanned spacecraft deployed to Mars in 2008.

Large gaps found in public understanding of climate change

New Haven, Conn.—Sixty-three percent of Americans believe that global warming is happening, but many do not understand why, according to a national study conducted by researchers at Yale University.

Physicists pave the way for graphene-based spin computer

RIVERSIDE, Calif. – Physicists at the University of California, Riverside have taken an important step forward in developing a "spin computer" by successfully achieving "tunneling spin injection" into graphene.

Breaking curveball too good to be true?

Curveballs curve and fastballs are fast, but new research suggests that no pitcher can make a curveball "break" or a fastball "rise."

Led by Arthur Shapiro of American University and Zhong-Lin Lu of the University of Southern California, the researchers explain the illusion of the curveball's break in a publicly available study in the journal PLoS ONE.

Why it's hard to crash the electric grid

Why it's hard to crash the electric grid

Last March, the U.S. Congress heard testimony about a scientific study in the journal Safety Science. A military analyst worried that the paper presented a model of how an attack on a small, unimportant part of the U.S. power grid might, like dominoes, bring the whole grid down.

Gambling on bacteria

When it comes to gambling, many people rely on game theory, a branch of applied mathematics that attempts to measure the choices of others to inform their own decisions. It's used in economics, politics, medicine -- and, of course, Las Vegas. But recent findings from a Tel Aviv University researcher suggest that we may put ourselves on the winning side if we look to bacteria instead.

Canadian leads publishing of first results from Large Hadron Collider

Researchers used Einstein's famous E=mc2 equation and the Large Hadron Collider to recreate a miniature version of the event at the origins of our Universe, and the first findings from their work were published in the journal Physical Review Letters. Dr. Andreas Warburton of McGill's Department of Physics made leading contributions to the analysis of data from the experiment, known as "ATLAS," meaning the findings have a special significance for Canadian science.
