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.

RAMBO a small but powerful magnet
Rice pioneers a tabletop magnetic pulse generator that allows researchers to collect real-time, high-resolution data in a system that couples high magnetic fields and low temperature with direct optical access to the magnet's core.

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.

New compounds discovered that are hundreds of times more mutagenic
Researchers have discovered novel compounds produced by certain types of chemical reactions -- such as those found in vehicle exhaust or grilling meat -- that are hundreds of times more mutagenic than their parent compounds which are known carcinogens. These compounds were not previously known to exist.

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.

Yeast's lifestyle couples mating with meiosis
Mating and meiosis -- the specialized cell division that reduces the number of chromosomes in a cell -- are related, but in most yeasts they are regulated separately. Not so in Candida lusitaniae, where the two programs work in unison, according to a new study in Nature. Comparison with other species suggests that this fusion may support C. lusitaniae's "haploid lifestyle" of maintaining only one set of chromosomes in each cell.

Reconstructing the New World monkey family tree
A Duke scientist has reconstructed the most comprehensive family tree to date of the monkeys that arrived in South America 37 or more million years ago and their subsequent evolution. The research uncovered several patterns, suggesting, among other things, that sea level rise and the arrival of humans likely caused the extinction of monkeys native to the Caribbean islands, and that monkeys once lived in the extreme southern reaches of South America.

Local factors cause dramatic spikes in coastal ocean acidity
Seawater samples collected from the marine estuary Beaufort Inlet, N.C., weekly for a year and on a daily and hourly basis for shorter periods were used to track changes in pH and dissolved inorganic carbon. Short-term variability in acidity over one year exceeds 100-year global predictions for the ocean as a whole and may already be exerting added pressure on some of the estuary's organisms, particularly shelled organisms.

Genetically identical bacteria can behave in radically different ways
When a bacterial cell divides into two daughter cells there can be an uneven distribution of certain survival mechanisms. The resulting cells can behave differently from each other, depending on which parts they received in the split. This is another way that cells within a population can diversify and enhance the odds that some members of a population of bacteria can avoid threats, such as antibiotics.

Competition in a rough neighborhood: Plant success in a desert environment
In deserts, variable weather is common so that plant community patterns can change between wet and dry years, with high densities and a diversity of plants in wet years, and a reduction in both quantity and number of species in dry years. The effect that two important variables have on plant communities -- competition and water usage -- was investigated in the Sonoran Desert by a research group at the University of Arizona.

Mangroves expand north as Florida freezes decline
Climate change appears to have paved the way for a northward march of mangrove forest along Florida's Atlantic coast, but not because mean temperatures are rising. Instead a new analysis of satellite images and other data over a 28-year span attributes the dramatic expansion of mangrove to a decline in frequency of days where the temperature dips below negative 4 degrees Celsius (25 degrees Farenheit).

Genetic discovery points the way to much bigger yields in tomato, other flowering food plants
CSHL researchers announced that they have determined a way to dramatically increase tomato production. Their research has revealed a genetic mechanism for hybrid vigor, a property of plant breeding that has long been exploited to boost yield. Teasing out the hidden subtleties of a type of hybrid vigor involving just one gene has provided the scientists with means to extend the length of time that specific tomato varieties can produce flowers, substantially raising fruit yield.
