Acid mine drainage reduces radioactivity in fracking waste
Blending fracking wastewater with acid mine drainage causes most of the naturally radioactive metals in the fracking water to precipitate into a solid for disposal. The practice also could help reduce the depletion of local freshwater resources by giving drillers a source of usable recycled water for the hydraulic fracturing process.

Surprising new class of 'hypervelocity stars' discovered escaping the galaxy
An international team of astronomers has discovered a surprising new class of "hypervelocity stars" -- solitary stars moving fast enough to escape the gravitational grasp of the Milky Way galaxy.

Coral chemical warfare: Suppressing a competitor enhances susceptibility to a predator
Competition may have a high cost for at least one species of tropical seaweed. Researchers examining the chemical warfare taking place on Fijian coral reefs have found that one species of seaweed increases its production of noxious anti-coral compounds when placed into contact with reef-building corals, but at the same time becomes more attractive to herbivorous fish.

Many small exoplanets found to be covered in gas
NASA's Kepler space telescope discovered thousands of "planetary candidates," but what are the planets made of? To know this, each planet's mass first must be determined. A Northwestern University astronomer reports having measured the masses of approximately 60 exoplanets larger than Earth and smaller than Neptune. The measurements greatly expand scientists' knowledge of sub-Neptune exoplanets because once the mass and size of a planet are known, the density can be determined and the composition of the planet inferred.

Researchers propose alternative way to allocate science funding
Researchers in the United States have suggested an alternative way to allocate science funding. The method, which is described in EMBO reports, depends on a collective distribution of funding by the scientific community, requires only a fraction of the costs associated with the traditional peer review of grant proposals and, according to the authors, may yield comparable or even better results.

Fungi may determine the future of soil carbon
Soil contains more carbon than air and plants combined. This means that even a minor change in soil carbon could have major implications for the Earth's atmosphere and climate. New research by Smithsonian Tropical Research Institute scientist Benjamin Turner and colleagues at the University of Texas, Austin, and Boston University points to an unexpected driver of soil carbon content: fungi.

Researchers unveil rich world of fish biofluorescence
A team led by scientists from the American Museum of Natural History has released the first report of widespread biofluorescence in fishes, identifying more than 180 species that glow in a wide range of colors and patterns. Published today in PLOS ONE, the research shows that biofluorescence -- a phenomenon by which organisms absorb light, transform it, and eject it as a different color -- is common and variable among marine fish species, indicating its potential use in communication and mating.

Symbiotic fungi inhabiting plant roots have major impact on atmospheric carbon, scientists say
Microscopic fungi that live in plants' roots play a major role in the storage and release of carbon from the soil into the atmosphere, according to a University of Texas at Austin researcher and his colleagues at Boston University and the Smithsonian Tropical Research Institute. The role of these fungi is currently unaccounted for in global climate models.

BOSS measures the universe to 1-percent accuracy
The Baryon Oscillation Spectroscopic Survey (BOSS), led by scientists at Lawrence Berkeley National Laboratory, is the largest component of the third Sloan Digital Sky Survey. BOSS has measured the clustering of nearly 1.3 million galaxies spectroscopically, determining the "standard ruler" of the universe's large-scale structure to within one percent. This is the most precise such measurement ever made and likely to be the standard for years to come.

Of lice and men (and chimps): Study tracks pace of molecular evolution
A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice. The researchers wanted to know whether evolution marches on at a steady pace in all creatures or if subtle changes in genes -- substitutions of individual letters of the genetic code -- occur more rapidly in some groups than in others.

Scientists to examine Pacific's 'global chimney'
NCAR scientists and partners next week launch a field project in the tropical Pacific, a remote region that holds a key to understanding worldwide climate. The warm waters fuel huge clusters of thunderstorms that act as a global chimney, lofting gases and particles into the stratosphere and affecting the planet.

Babbling babies -- responding to one-on-one 'baby talk' -- master more words
Common advice to new parents is that the more words babies hear the faster their vocabulary grows. Now new findings show that what spurs early language development isn't so much the quantity of words as the style of speech and social context in which speech occurs.

Worker wasps grow visual brains, queens stay in the dark
A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new Drexel University study indicates that the brain regions involved in sensory perception also develop differently in these castes, according to the different behavioral reliance on the senses. The study is published in Behavioral Ecology and Sociobiology.

Discovery spotlights key role of mystery RNA modification in cells
Researchers had known for several decades that a certain chemical modification exists on messenger ribonucleic acid, which is essential to the flow of genetic information. But only recently did experiments at the University of Chicago show that one major function of this modification governs the longevity and decay of RNA, a process critical to the development of healthy cells.

Suburban sprawl cancels carbon footprint savings of dense urban cores
According to a new study by UC Berkeley researchers, population-dense cities contribute less greenhouse gas emissions per person than other areas of the country, but these cities' extensive suburbs essentially wipe out the climate benefits. Dominated by emissions from cars, trucks and other forms of transportation, suburbs account for about 50 percent of all household emissions -- largely carbon dioxide -- in the United States.

Newfound planet is Earth-mass but gassy
An international team of astronomers has discovered the first Earth-mass planet that transits, or crosses in front of, its host star. KOI-314c is the lightest planet to have both its mass and physical size measured. Surprisingly, although the planet weighs the same as Earth, it is 60 percent larger in diameter, meaning that it must have a very thick, gaseous atmosphere.

Pulsar in stellar triple system makes unique gravitational laboratory
The discovery of a millisecond pulsar -- a superdense neutron star -- in a triple system with two white dwarfs gives astronomers the most precise tool yet for studying the gravitational three-body problem. In addition, the nature of the stars and their interactions may give an unprecedented clue that points toward a new theory of gravity compatible, unlike general relativity, with quantum theory.
