Electricity from biomass with carbon capture could make western US carbon-negative
Biomass conversion to electricity combined with technologies for capturing and storing carbon, which should become viable within 35 years, could result in a carbon-negative power grid in the western US by 2050. That prediction comes from an analysis by UC Berkeley's Daniel Kammen and Daniel Sanchez, who modeled various fuel scenarios using their SWITCH model. Bioenergy with carbon capture and sequestration may be a better use of plant feedstocks than making biofuels.

Bringing texture to your flat touchscreen
What if the touchscreen of your smartphone or tablet could touch you back? Northwestern University and Carnegie Mellon University researchers now report a discovery that provides insight into how the brain makes sense of data from fingers. When people draw their fingers over a flat surface with two 'virtual bumps,' the researchers found that, under certain circumstances, the subjects feel only one bump when there really are two. And the researchers can explain why the brain comes to this conclusion.

Controlling genes with light
Researchers at Duke University have demonstrated a new way to activate genes with light, allowing precisely controlled and targeted genetic studies and applications. The method might be used to activate genes in a specific location or pattern, allowing more precise study of gene function, or to create complex systems for growing tissue or new therapies.

Bionic leaf
Solar energy can be harnessed using electricity from photovoltaic cells to yield hydrogen that can be stored in fuel cells. But hydrogen has failed to catch on as a practical fuel for cars or for power. Converting solar energy into liquid fuel could accelerate its adoption as a power source.

Earth's surprise inside: Geologists unlock mysteries of the planet's inner core
Seismic waves are helping scientists to plumb the world's deepest mystery: the planet's inner core. Thanks to a novel application of earthquake-reading technology, a research team at the University of Illinois and colleagues at Nanjing University in China have found that the Earth's inner core has an inner core of its own, which has surprising properties that could reveal information about our planet.

F-bombs notwithstanding, all languages skew toward happiness
Arabic movie subtitles, Korean tweets, Russian novels, Chinese websites, English lyrics, and even the war-torn pages of the New York Times -- Big Data research from the University of Vermont, examining billions of words, shows that these sources -- and all human language -- skews toward the use of happy words. This study confirms the 1969 Pollyanna Hypothesis that there is a universal human tendency to 'look on and talk about the bright side of life.'

A nanoscale solution to the big problem of overheating in microelectronic devices
Currently, microelectronic device manufacturers must rely on simulations alone to understand the temperatures inside individual devices. A team of USC and UCLA researchers has developed a way to determine actual temperatures within these devices by using material within them as its own thermometer.

Cesium atoms shaken, not stirred, to create elusive excitation in superfluid
In 1941, future Nobel laureate Lev Landau predicted that superfluid helium-4 should contain an exotic, particle-like excitation called a roton. Roton structure has been a matter of debate ever since. University of Chicago physicists have now created roton structure in the laboratory.

Seafloor volcano pulses may alter climate
A new study shows that undersea volcanoes flare up on strikingly regular cycles, ranging from two weeks to 100,000 years -- and, that they erupt almost exclusively during the first six months of each year. The pulses -- apparently tied to short- and long-term changes in earth's orbit, and to sea levels -- may help trigger natural climate swings.

MRI technique developed for nonalcoholic fatty liver disease in children
Between 5 and 8 million children in the United States have nonalcoholic fatty liver disease (NAFLD), yet most cases go undiagnosed. To help address this issue, researchers at UC San Diego School of Medicine have developed a new magnetic resonance imaging (MRI)-based technique to help clinicians and researchers better detect and evaluate NAFLD in children.

Shade coffee is for the birds
The conservation value of growing coffee under trees instead of on open farms is well known, but hasn't been studied much in Africa. So a University of Utah-led research team studied birds in the Ethiopian home of Arabica coffee and found that 'shade coffee' farms are good for birds, but some species do best in forest.

Scientists reprogram plants for drought tolerance
A team led by a University of California, Riverside plant biologist reports that drought tolerance in plants can be improved by engineering them to activate water-conserving processes in response to an agrochemical already in use -- an approach that could be broadly applied to other parts of the same drought-response pathway and a range of other agrochemicals. The finding illustrates the power of synthetic biological approaches for manipulating crops, opening new doors for crop improvement.

Fruitful collaboration yields insight on the tomato genome
Plant biologists Julin Maloof and Neelima Sinha collaborate to understand how wild and cultivated tomato species thrive in disparate environments. Using resources at the iPlant Collaborative, the researchers managed their increasing data and perform analyses on big datasets in a collaborative environment. Maloof and Sinha's work will not only advance the scientific community, but can also help the crop industry develop crops that can withstand periods of prolonged heat or drought.

New findings on how the brain ignores distractions

Rivers might constitute just 20 percent of continental water flowing into oceans
The Amazon, Nile and Mississippi are mighty rivers, but they and all their worldwide brethren might be a relative trickle compared with an unseen torrent below the surface. New research shows that rivers might constitute as little as 20 percent of the water that flows yearly into the Atlantic and Indo-Pacific Oceans from the continents. The rest flows through what is termed the 'subterranean estuary,' which some researchers think supply the lion's share of terrestrial nutrients to the oceans.
