Light switches help convert carbon dioxide into organic substances

October 20, 2014 12:50 pm | by EurekAlert! | Comments

Diatoms play an important role in water quality and in the global climate. They generate about one fourth of the oxygen in the Earth's atmosphere and perform around one-quarter of the global CO2 assimilation, i.e. they convert carbon dioxide....

Teachers know technology better than their students

October 20, 2014 12:40 pm | by EurekAlert! | Comments

Members of today's younger Net Generation aren't more tech savvy than their teachers just because they were born into a world full of computers. In fact, if it weren't for the coaxing and support of their educators, many students would never use....

New ways to create "smart materials"

October 20, 2014 12:35 pm | by EurekAlert! | Comments

Microscopic particles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of New York University scientists has found. Their discovery points to new ways to create "smart materials"....

Switching on a laser by taking energy away

October 20, 2014 12:31 pm | by EurekAlert! | Comments

What started out as a mathematical oddity, has now become a new kind of laser technology. Two years ago, physicists at TU Wien predicted a paradoxical laser effect: Under certain conditions, a laser can be switched on not by supplying it with more energy....

Wobbling of a Saturn moon hints at what lies beneath

October 20, 2014 8:45 am | by EurekAlert! | Comments

Using instruments aboard the Cassini spacecraft to measure the wobbles of Mimas, the closest of Saturn's regular moons, a Cornell University astronomer publishing in Science, Oct. 17, has inferred that this small moon's icy surface cloaks either ...

Magnetic fields form cosmic jets of young stars

October 20, 2014 8:42 am | by EurekAlert! | Comments

Astrophysical jets are counted among our Universe's most spectacular phenomena: From the centers of black holes, quasars, or protostars, these rays of matter sometimes protrude several light years into space. Now, for the first time ever, an international team ...

Electricity access marginally related to climate change

October 20, 2014 8:39 am | by EurekAlert! | Comments

Improving household electricity access in India over the last 30 years contributed only marginally to the nation's total carbon emissions growth during that time, according to a new study published in the journal Nature Climate Change. "Energy access is fundamental....

How offshore wind power is affecting marine life

October 17, 2014 12:32 pm | by University of Maryland Center for Environmental Science | Comments

Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. In a recent paper, University of Maryland Center for Environmental Science researcher...
