To predict disease researchers ask if plant neighbors are relatives
Disease shapes plant communities and determines the outcomes of environmental change, weed invasions and agriculture and forestry management strategies. Whether or not a disease devastates a plant community depends on how related the plant species are and on how many individual plants of each species are present.

'Holey' graphene for energy storage
Engineers at the University of California, San Diego have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research, published recently online in the journal Nano Letters, may provide a better understanding of how to improve the energy storage ability of capacitors for potential applications in cars, wind turbines, and solar power.

Global warming progressing at moderate rate, empirical data suggest
A study based on 1,000 years of temperature records suggests global warming is not progressing as fast as it would under the most severe emissions scenarios outlined by the Intergovernmental Panel on Climate Change. Natural decade-to-decade variability in surface temperatures can account for some much-discussed recent changes in the rate of warming. Empirical data, rather than climate models, were used to estimate this variability.

Getting better all the time: JILA strontium atomic clock sets new records
In another advance at the far frontiers of timekeeping by National Institute of Standards and Technology researchers, the latest modification of a record-setting strontium atomic clock has achieved precision and stability levels that now mean the clock would neither gain nor lose one second in some 15 billion years -- roughly the age of the universe.

OSU innovation boosts Wi-Fi bandwidth tenfold
Researchers have invented a new technology that can increase the bandwidth of Wi-Fi systems by 10 times, using LED lights to transmit information. It could be integrated with existing Wi-Fi systems to reduce bandwidth problems in crowded locations, such as airport terminals or coffee shops, and in homes where several people have multiple Wi-Fi devices.

Big butts aren't everything to male baboons
While the female baboon's big red bottom may be an eyesore to some, it has an aphrodisiac effect on her mates. Biologists have long thought that baboon males prefer females with bigger backsides as the mark of a good mother, but a Duke study reveals that the size of a female's swollen rump doesn't matter as much as previously thought.

Pulsing light may indicate supermassive black hole merger
As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a 'binary,' or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers at the University of Maryland present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.

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.
