Life in Earth’s primordial sea was starved for sulfate

November 7, 2014 3:18 pm | by Univ. of British Columbia | Comments

The Earth’s ancient oceans held much lower concentrations of sulfate— a key biological nutrient— than previously recognized, according to new research.

Greater use of social media gets scientists noticed

November 7, 2014 3:14 pm | by Chris Barncard, Univ. of Wisconsin | Comments

Here is an idea worth following: “share” for tenure; “like” to get cited. Academic researchers are turning to social media more and more, according to new research.

Purdue innovation might make MR imaging more effective, less toxic

November 7, 2014 10:17 am | by Purdue Univ. | Comments

Researchers led by David Thompson, president of Aten Biotherapeutics and a professor in Purdue's Department of Chemistry, are developing controlled-release imaging agents that allow for a longer, safer imaging session.

A promising strategy against HIV

November 7, 2014 10:09 am | by B. D. Colen, Harvard Univ. | Comments

Harvard Stem Cell Institute (HSCI) researchers at Massachusetts General (MGH) and Boston Children’s hospitals (BCH) for the first time have used a relatively new gene-editing technique to create what could prove to be an effective technique for blocking HIV from invading and destroying patients’ immune systems.

New model predicts how traffic will flow

November 7, 2014 10:01 am | by David Chandler, MIT | Comments

A reliable way of predicting the flow of traffic could be a great convenience for commuters, as well as a significant energy-saver. Now a team of researchers from MIT, the Univ. of Notre Dame, and elsewhere has devised what they say is an effective and relatively simple formula for making such predictions.

Thermomagnetic processing method provides path to new materials

November 7, 2014 9:49 am | by ORNL | Comments

For much the same reason LCD televisions offer eye-popping performance, a thermomagnetic processing method developed at the Department of Energy’s Oak Ridge National Laboratory can advance the performance of polymers.

How to make mobile batteries last longer

November 7, 2014 9:42 am | by Univ. of Luxembourg | Comments

Electronic devices waste a lot of energy by producing useless heat. Researchers have made a leap forward in understanding how this happens and how this waste could be reduced by controlling energy flows at a molecular level.

Satellites assist in Ebola management

November 7, 2014 9:37 am | by UK Space Agency | Comments

The UK's International Charter for Space and Major Disasters (the Charter) is an international agreement between space agencies to provide free satellite images in the immediate aftermath of natural or man-made disasters.

3-D printing a lunar base

November 7, 2014 9:29 am | by European Space Agency | Comments

Could astronauts one day be printing rather than building a base on the Moon? In 2013 ESA, working with industrial partners, proved that 3-D printing using lunar material was feasible in principle. Since then, work continues to investigate the technique.

Wind energy reaches greater heights

November 6, 2014 3:14 pm | by Rob Matheson, MIT | Comments

Wind turbines across the globe are being made taller to capture more energy from the stronger winds that blow at greater heights. But it’s not easy, or sometimes even economically feasible, to build taller towers, with shipping constraints on tower diameters and the expense involved in construction.

Synthetic biology for space exploration

November 6, 2014 3:13 pm | by Lynn Yarris, Berkeley Lab | Comments

Does synthetic biology hold the key to manned space exploration of the Moon and Mars? Berkeley Lab researchers have used synthetic biology to produce an inexpensive and reliable microbial-based alternative to the world’s most effective anti-malaria drug.

Researchers hit milestone in accelerating plasma particles

November 6, 2014 3:04 pm | by SLAC National Accelerator Laboratory | Comments

Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the Univ. of California, Los Angeles have shown that a promising technique for accelerating electrons on waves of plasma is efficient enough to power a new generation of shorter, more economical accelerators.

Adding 'spice' to curcumin’s health-promoting benefits

November 6, 2014 2:55 pm | by Emily Caldwell, The Ohio State Univ. | Comments

The health benefits of over-the-counter curcumin supplements might not get past your gut, but new research shows that a modified formulation of the spice releases its anti-inflammatory goodness throughout the body.

Clearing a path for electrons in polymers

November 6, 2014 2:53 pm | by Univ. of Cambridge | Comments

A new class of low-cost polymer materials, which can carry electric charge with almost no losses despite their seemingly random structure, could lead to flexible electronics and displays which are faster and more efficient.
