New research could lead to more efficient electrical energy storage

March 4, 2015 11:52 am | by Anne M. Stark, Lawrence Livermore National Laboratory | Comments

Lawrence Livermore National Laboratory researchers have identified electrical charge-induced changes in the structure and bonding of graphitic carbon electrodes that may one day affect the way energy is stored. The research could lead to an improvement in the capacity and efficiency of electrical energy storage systems needed to meet the burgeoning demands of consumer, industrial and green technologies.

Study could change nuclear fuel

March 4, 2015 11:44 am | by David Goddard, UT Knoxville | Comments

The adverse effects of radiation on nuclear fuel could soon be better controlled thanks to research involving Univ. of Tennessee at Knoxville's College of Engineering. Maik Lang, an assistant nuclear engineering professor, is part of a team of researchers that has studied how specific properties of materials involved in nuclear energy production, and their performance, can change their response to radiation.

How big data can be used to understand major events

March 4, 2015 11:38 am | by Joanne Fryer, Univ. of Bristol | Comments

With the most unpredictable U.K. general election looming in modern times, how can big data be used to understand how elections are covered by the media? New research has, for the first time, analyzed over 130,000 online news articles to find out how the 2012 U.S. presidential election played out in the media.

Higgs particle can disintegrate into particles of dark matter

March 4, 2015 11:30 am | by Chalmers Univ. of Technology | Comments

The Standard Model of particle physics successfully describes the smallest constituents of matter. But the model has its limitations: It does not explain the dark matter of the universe. A research scientist at Chalmers Univ. of Technology has found a solution; and his theories are now being tested at the particle physics laboratory CERN.

Pennies reveal new insights on the nature of randomness

March 4, 2015 11:22 am | by Tien Nguyen, Princeton Univ. | Comments

The concept of randomness appears across scientific disciplines, from materials science to molecular biology. Now, theoretical chemists at Princeton Univ. have challenged traditional interpretations of randomness by computationally generating random and mechanically rigid arrangements of 2-D hard disks, such as pennies, for the first time.

Experiment and theory unite in debate over microbial nanowires

March 4, 2015 11:12 am | by Janet Lathrop, Univ. of Massachusetts, Amherst | Comments

Scientific debate has been hot lately about whether microbial nanowires, the specialized electrical pili of the mud-dwelling anaerobic bacterium Geobacter sulfurreducens, truly possess metallic-like conductivity as its discoverers claim. But now a Univ. of Massachusetts Amherst team says they settled the dispute between theoretical and experimental scientists by devising a combination of new experiments and better theoretical modeling.

Neuroscientists identify new way brain areas communicate

March 4, 2015 11:04 am | by Shilo Rea, Carnegie Mellon Univ. | Comments

Carnegie Mellon Univ. neuroscientists have identified a new pathway by which several brain areas communicate within the brain’s striatum. The findings illustrate structural and functional connections that allow the brain to use reinforcement learning to make spatial decisions, such as the dorsolateral prefrontal, orbitofrontal cortex and posterior parietal cortex.

Energy-generating cloth could replace batteries in wearable devices

March 4, 2015 10:25 am | by American Chemical Society | Comments

From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets’ versatility is still held back by the stiff, short-lived batteries that are required. These limitations, however, could soon be overcome.

Material captures carbon dioxide with high capacity

March 4, 2015 8:36 am | by Amanda Bradford, New Mexico State Univ. | Comments

A new provisionally patented technology from a New Mexico State Univ. researcher could revolutionize carbon dioxide capture and have a significant impact on reducing pollution worldwide. Through research on zeolitic imidazolate frameworks, or ZIFs, the researcher synthesized a new subclass of ZIF that incorporates a ring carbonyl group in its organic structure.

Genome reveals how Hessian fly causes galls in wheat

March 4, 2015 8:14 am | by Natalie van Hoose, Purdue Univ. | Comments

A team of researchers from 26 institutions around the world has sequenced the Hessian fly genome, shedding light on how the insect creates growth-stunting galls in wheat. Hessian fly larvae can destroy entire wheat fields by injecting seedlings with potent saliva that "hijacks" the plants' biochemistry, irreversibly halting development and forcing the seedlings to produce a leaky tissue that contains nutrients for the larvae.

DNA supports human migration theory

March 3, 2015 3:55 pm | by Associated Press | Comments

A wave of migrants from the eastern fringes of Europe some 4,500 years ago left their trace in the DNA—and possibly the languages—of modern Europeans, according to a new study. Scientists discovered evidence of this Stone Age migration by analyzing the DNA of 69 people who lived across Europe between 8,000 and 3,000 years ago.

New material to produce clean energy

March 3, 2015 3:36 pm | by Jeannie Kever, Univ. of Houston | Comments

Researchers at the Univ. of Houston have created a new thermoelectric material, intended to generate electric power from waste heat with greater efficiency and higher output power than currently available materials. The material, germanium-doped magnesium stannide, has a peak power factor of 55, with a figure of merit of 1.4.

Providing data for nuclear detectives

March 3, 2015 3:26 pm | by Breanna Bishop, Lawrence Livermore National Laboratory | Comments

Fans of the popular TV series “CSI” know that the forensics experts who investigate crime scenes are looking for answers to three key questions: “Who did it; how did they do it; and can we stop them from doing it again?” The field of nuclear forensics, an important element of Lawrence Livermore National Laboratory’s national security mission, has similar goals and uses similar techniques, but with even higher stakes.

Why seashells’ mineral forms differently in seawater

March 3, 2015 3:16 pm | by David L. Chandler, MIT News Office | Comments

For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth’s oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take the form of calcite, and at other times form a chemically identical form of the mineral, called aragonite, that is more soluble—and therefore more vulnerable to ocean acidification?

Health officials perplexed by vaccination skeptics

March 3, 2015 3:08 pm | by Mike Stobbe, AP Medical Writer, Associated Press | Comments

Certain that they are right, struggling to find ways to get their message across, public health officials are exasperated by their inability to convince more U.S. parents to vaccinate their children. They say they are contending with a small minority of parents who are misinformed about the risks of inoculations.
