A cosmic barbecue: Researchers spot 60 new 'hot Jupiter' candidates

Kinky biology
How and why proteins fold is a problem that has implications for protein design and therapeutics. Researchers from the University of Texas Medical Branch are exploring protein folding in bacteriophage DNA and other systems using advanced computing resources at the Texas Advanced Computing Center. Recent studies suggest the introduction of 'kinks' into configurations of DNA packaged within spherical confinement lowers energies and pressures and allows for compression. Results appeared in the Journal of Computational Chemistry.

Early-life pain may lead to obesity risk, especially in females, study finds
Inflammatory pain at birth changes how the hippocampus, a part of the brain associated with memory and eating behavior, works later in life, and this pain also causes adult rats to eat more frequently and in larger amounts, according to a study by Georgia State University and the Charlie Norwood VA Medical Center.

Cutting the cost of ethanol, other biofuels and gasoline
Biofuels like the ethanol in US gasoline could get cheaper thanks to experts at Rutgers University-New Brunswick and Michigan State University. They've demonstrated how to design and genetically engineer enzyme surfaces so they bind less to corn stalks and other cellulosic biomass, reducing enzyme costs in biofuels production, according to a study published this month on the cover of the journal ACS Sustainable Chemistry & Engineering.

Reconciling predictions of climate change
Harvard researchers have resolved a major conflict in estimates of how much the Earth will warm in response to a doubling of CO2 in the atmosphere -- finding that the lower range of estimates offered by historical observations does not take into account long-term patterns of warming. The research finds a range of 1.5 to 4.5 degrees Celsius, even up to 6 degrees, may also be possible due to a doubling of CO2.

Dinosaurs' loss was frogs' gain: The upside of a mass extinction
Based on earlier studies, biologists believed that the vast majority of today's frogs originated in a blossoming of new species 100 million years ago. New and more complete genetic data pinpoints this radiation much earlier: 66 million years ago at the Cretaceous-Paleogene boundary, precisely when much of life on Earth was wiped out by a comet or asteroid. Frogs took advantage of flourishing angiosperms to escape to the treetops into many more ecological niches.

Utah is home to earliest use of a wild potato in North America
Researchers have discovered potato starch residues in the crevices of a 10,900-year-old stone tool in Escalante, Utah -- the earliest evidence of wild potato use in North America. This is the first archaeological study to identify Solanum jamesii, a wild species native to the southwestern United States, as an important part of ancient human diets. The long history could mean that the species was transported, cultivated or even domesticated.
