Substance in photosynthesis was at work in ancient, methane-producing microbes
An international team of researchers led by scientists at Virginia Tech and the University of California, Berkeley has discovered that a process that turns on photosynthesis in plants likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available. The research offers new perspective on evolutionary biology, microbiology, and the production of natural gas, and may shed light on climate change, agriculture, and human health.

New insight into an emerging genome-editing tool
A collaboration led by Berkeley Lab's Jennifer Doudna and Eva Nogales has produced the first detailed look at the 3D structure of the Cas9 enzyme and how it partners with guide RNA to interact with target DNA. The results should enhance Cas9's value and versatility as a genome-editing tool.

Research on pigeon color reveals mutation hotspot
University of Texas at Arlington researchers worked in parallel with researchers at the University of Utah to examine three genes that control multiple color phenotypes, or appearances, in pigeons. The UT Arlington team found two independent deletions of regulatory sequences near the Sox10 gene produce "recessive red" pigmentation. These mutations happened at different points in evolution, and researchers believe it is no coincidence they hit the same spot.

Heavy metal in the early cosmos
Using the Stampede, Lonestar and Ranger supercomputers, University of Texas researchers simulated the formation of the Universe from the Big Bang through the first few hundred million years of its existence. The researchers found that more realistic models of supernova blasts help explain the range of metalicity found in different galaxies. The results of the simulations will assist in guiding the James Webb Space Telescope, set to launch in 2018.

Quarks in the looking glass
A recent experiment carried out at DOE's Jefferson Lab has determined how much of the mirror-symmetry breaking in the electron-quark interaction originates from quarks' spin preference in the weak interaction five times more precisely than a previous measurement. The result has also set new limits, in a way complementary to high-energy colliders such as the Large Hadron Collider at CERN, for the energies that researchers would need to access physics beyond the Standard Model.

Presence of humans and urban landscapes increase illness in songbirds, researchers find
Humans living in densely populated urban areas have a profound impact not only on their physical environment, but also on the health and fitness of native wildlife. For the first time, scientists have found a direct link between the degree of urbanization and the prevalence and severity of two distinct parasites in wild house finches. Loss of natural habitat may be a driving force behind increases in avian parasite infections.

Off-the-shelf materials lead to self-healing polymers
Look out, super glue and paint thinner. Thanks to new dynamic materials developed at the University of Illinois, removable paint and self-healing plastics soon could be household products. A slight tweak in chemistry to elastic materials made of polyurea, one of the most widely used classes of polymers in consumer goods, yields materials that bond back together on a molecular level without the need for other chemicals or adhesives.

Sucker-footed fossils broaden the bat map
Today, Madagascar sucker-footed bats live nowhere outside their island home, but new research shows that hasn't always been the case. The discovery of the jawbones of two extinct relatives in northern Egypt suggests the unusual creatures, which evolved sticky footpads to roost on slick surfaces, are primitive members of a group of bats that evolved in Africa and ultimately went on to flourish in South America.
