Beyond the lithium ion -- a significant step toward a better performing battery
Researchers at the University of Illinois at Chicago have taken a significant step toward the development of a battery that could outperform the lithium-ion technology used in electric cars such as the Chevy Volt. They have shown they can replace the lithium ions, each of which carries a single positive charge, with magnesium ions, which have a plus-two charge, in battery-like chemical reactions, using an electrode with a structure like those in many of today's devices.

Study finds that maize roots have evolved to be more nitrogen efficient
Selective breeding of maize over the last century to create hybrids with desirable shoot characteristics and increased yield may have contributed indirectly to the evolution of root systems that are more efficient in acquiring nutrients, such as nitrogen, from the soil, according to researchers.

Tunneling across a tiny gap
Researchers at MIT, the University of Oklahoma, and Rutgers University have developed a model that explains how heat flows between objects separated by gaps of less than a nanometer. The team has developed a unified framework that calculates heat transport at finite gaps, and has shown that heat flow at sub-nanometer distances occurs not via radiation or conduction, but through 'phonon tunneling.'

Climate change, plant roots may accelerate carbon loss from soils
Soil, long thought to be a semi-permanent storehouse for ancient carbon, may be releasing carbon dioxide to the atmosphere faster than anyone thought. In a study published in Nature Climate Change, researchers showed that chemicals emitted by plant roots act on carbon that is bonded to minerals in the soil, breaking the bonds and exposing previously protected carbon to decomposition by microbes.

Optics, nanotechnology combined to create low-cost sensor for gases
Engineers have combined innovative optical technology with nanocomposite thin-films to create a new type of sensor that is inexpensive, fast, highly sensitive and able to detect and analyze a wide range of gases. It may find applications in everything from environmental monitoring to airport security or testing blood alcohol levels -- and is particularly suited to detecting carbon dioxide.

Pick a color, any color
A small team of chemists, having learned the secrets of light absorption from chlorophylls a and b, can now tune molecules to absorb anywhere in the solar spectrum. They are using this facility to synthesize pigments that fill gaps in the sunlight absorbed by native pigments and to push deeper into the infrared than any native pigment.

Drop the bounce test: A common battery test often bounces off target
The battery bounce test, popularized in online videos, has led to the common conclusion that a high bounce means a dead battery. But researchers at Princeton University have found that bouncing is not actually an effective way to check a battery's charge.

UNH geologist identifies new source of methane for gas hydrates in Arctic
Researchers have identified a new source of methane for gas hydrates -- ice-like substances found in sediment that trap methane within the crystal structure of frozen water -- in the Arctic Ocean. The findings, published online now in the May 2015 journal Geology, point to a previously undiscovered, stable reservoir for methane that is 'locked' away from the atmosphere, where it could impact global climate change.

Glimpses of the future: Drought damage leads to widespread forest death
The 2000-2003 drought in the American southwest triggered a widespread die-off of forests around the region. A team of scientists developed a new modeling tool to explain how and where trembling aspen forests died as a result of this drought, based on damage to the individual trees' ability to transport water. Their results suggest that more widespread die-offs of aspen forests triggered by climate change are likely by the 2050s.

New study shows bacteria can use magnetic particles to create a 'natural battery'
New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to work published in journal Science on March 27, the bacteria can load electrons onto and discharge electrons from microscopic particles of magnetite. This discovery holds out the potential of using this mechanism to help clean up environmental pollution, and other bioengineering applications.

Global water use may outstrip supply by mid-century
Population growth could cause demand for water to outpace supply by mid-century if current use levels continue. But it wouldn't be the first time this has happened, a Duke study finds. Using a mathematical model to analyze historic data, the researchers identified a regularly recurring pattern of time periods when demand for water outstripped supply, and shortages were resolved by technological advancements. The model projects a similar period of innovation could occur in coming decades.
