A test has been developed to check for contamination of shallow groundwater from unconventional gas extraction techniques, such as fracking.

The development could help monitor the safety of shale gas and coal bed methane extraction, which has sparked debate because of the perceived risks of water contamination.

RICHLAND, Wash. - Hybrid batteries that charge faster than conventional ones could have significantly better electrical capacity and long-term stability when prepared with a gentle-sounding way of making electrodes.

Plastics are all around us. They are found in containers and packing materials, children's toys, medical devices and electronics.

Unfortunately, plastics are also found in the ocean.

A 2015 paper published in Science estimates that anywhere from 4.8 million to 12.7 million metric tons of plastic were dumped into the ocean in 2010 alone. One metric ton equals approximately 2,200 pounds, roughly the weight of a Mazda Miata.

The current effort by the United States and its coalition partners is insufficient to achieve the lasting defeat of the Islamic State of Iraq and the Levant (ISIL) in Iraq and Syria, according to a new RAND report.

Successful conclusion of the campaign will require significantly increased effort by the United States across two fronts, said Linda Robinson, author of the study and a senior international policy analyst at RAND, a non-profit research organization.

LOGAN, UTAH, USA - All living things require nitrogen for survival, but the world depends on only two known processes to break nitrogen's ultra-strong bonds to allow conversion to a form humans, animals and plants can consume. One is a natural, bacterial process on which farmers have relied since the dawn of agriculture. The other is the century-old Haber-Bösch process, which revolutionized fertilizer production and spurred unprecedented growth of the global food supply.

Planning algorithms for teams of robots fall into two categories: centralized algorithms, in which a single computer makes decisions for the whole team, and decentralized algorithms, in which each robot makes its own decisions based on local observations.

No one is telling you what time to go to bed with this, but researchers are making a strong case that the duration and timing of your sleep are closely associated with whether your behavior is heart-healthy.

Night owls should take special note of a new study by University of Delaware researcher Freda Patterson and collaborators at the University of Pennsylvania, Drexel University and the University of Arizona College of Medicine, who found that the early-to-bed, early-to-rise approach aligns much better with cardiovascular health.

In the microscopic world, where the modern miniaturized machines at the new frontiers of technology operate, as long as there are only two particles, things are relatively simple. When other particles are added, however, the situation soon becomes more complicate than common sense would suggest. Imagine there are two people pushing a broken-down car: the total force is the sum of their forces. Similarly, if there are three people, it would be the sum of the force of these three people, and so on.

Irvine, Calif., April 20, 2016 -- University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft.

COLUMBIA, Mo. - The Centers for Disease Control and Prevention recommends that adults of all ages should engage in 150 or more minutes of moderate physical activity per week. Among adults 60 years of age or more, walking is the most common form of leisure-time physical activity because it is self-paced, low impact and does not require equipment. Researchers at the University of Missouri have determined that older adults who also are pet owners benefit from the bonds they form with their canine companions.

Behaviors that enable bullying--a significant public health problem for adolescents--were reduced among students who completed a new online anti-bullying program, according to a new study from Case Western Reserve University.

MADISON, Wis. -- One secret to creating the world's fastest silicon-based flexible transistors: a very, very tiny knife.

Working in collaboration with colleagues around the country, University of Wisconsin-Madison engineers have pioneered a unique method that could allow manufacturers to easily and cheaply fabricate high-performance transistors with wireless capabilities on huge rolls of flexible plastic.

Researchers at North Carolina State University have developed a model that allows antenna designers to identify efficient configurations for antenna designs in minutes, rather than days. The model is designed to expedite development of next generation "multi-input, multi-ouput" (MIMO) antennas, which allow devices to get more use out of the available bandwidth.

WASHINGTON - A team of researchers from across the country, led by Alexander Spott, University of California, Santa Barbara, USA, have built the first quantum cascade laser on silicon. The advance may have applications that span from chemical bond spectroscopy and gas sensing, to astronomy and free-space communications.
