 Proceedings of the National Academy of SciencesMapping the benefits of our ecosystems We rely on our physical environment for many things -- clean water, land for crops or pastures, storm water absorption, and recreation, among others. Yet it has been challenging to figure out how to sustain the many benefits people obtain from nature -- so-called "ecosystem services" -- in any given landscape because an improvement in one may come at the cost of another.

Proceedings of the National Academy of SciencesSurprise superconductor Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. This phenomenon can only be found in certain materials under specific low-temperature and high-pressure conditions. New research found unexpected superconductivity that could help scientists better understand the structural changes that create this rare phenomenon.

Journal of Environmental ManagementTallying the wins and losses of policy In the past decade, China as sunk some impressive numbers to preserve its forests, but until now there hasn't been much data to give a true picture of how it has simultaneously affected both the people and the environment. Michigan State University has capitalized on their long history of research in the Wolong Nature Reserve to get a complete picture of the environmental and socioeconomic effects of payments for ecosystem services programs.

Proceedings of the National Academy of SciencesPsychology influences markets When it comes to economics versus psychology, score one for psychology. Economists argue that markets usually reflect rational behavior -- with the dominant players in a market, such as hedge-fund managers, almost always making well-informed and objective decisions. But psychologists say that markets are not immune from human irrationality. A new analysis by Caltech researchers supports the latter case, showing that markets are indeed susceptible to psychological phenomena.

Proceedings of the National Academy of SciencesImproving crop yields in a world of extreme weather events When plants encounter drought, they naturally produce abscisic acid (ABA), a stress hormone that helps them cope with the drought conditions. Specifically, the hormone turns on receptors in the plants. A research team led by Sean Cutler at the University of California, Riverside has identified an inexpensive synthetic chemical, quinabactin, that mimics ABA. Spraying ABA on plants improves their water use and stress tolerance, but the procedure is expensive. Quinabactin now offers a cheaper solution.

Proceedings of the National Academy of SciencesNew forensic technique may help track illegal ivory A new method for dating elephant ivory, described in the latest issue of the Proceedings of the National Academy of Sciences, could make it easier to enforce the international ban on ivory and save the African elephant from extermination say researchers. The method might also be applied to endangered rhinoceroses and other wildlife.

Proceedings of the National Academy of SciencesNuke test radiation can fight poachers University of Utah researchers developed a new weapon to fight poachers who kill elephants, hippos, rhinos and other wildlife. By measuring radioactive carbon-14 deposited in tusks and teeth by open-air nuclear bomb tests, the method reveals the year an animal died, and thus whether the ivory was taken illegally.

Nature Climate ChangeEl Nino unusually active in the late 20th century Reliable prediction of El Nino response to global warming is difficult, as El Nino varies naturally over decades and centuries. Instrumental records are too short to determine whether recent changes are natural or attributable to increased greenhouse gases. An international team of scientists now show that recent El Nino activity is the highest for the past 700 years, possibly a response to global warming. The work is published in the June 30, 2013, online issue of Nature Climate Change.

Molecular Systems BiologyMimicking living cells: Synthesizing ribosomes Synthetic biology researchers at Northwestern University and Harvard Medical School have for the first time synthesized ribosomes from scratch in a test tube. The researchers took an approach different from their predecessors: they mimicked the natural synthesis of a ribosome, allowing natural enzymes of a cell to help facilitate the man-made construction. The technology could lead to the discovery of new antibiotics targeting ribosome assembly and the creation of tailor-made ribosomes to produce new proteins with exotic functions.

Science China Physics, Mechanics & AstronomyDetached-eddy simulations and analyses on new vortical flows over a 76/40 double delta wing Numerical simulations were performed on the massively separated flows of a 76/40° double delta wing using detached-eddy simulation. A new type of cross-flow vortex is proposed. Detailed analyses were made on the inviscid cross-flow instability generating the cross-flow vortex, which differs from that of the swept blunt wing. The analyses showed that the cross-flow vortices influence the pressure distribution, which can cause a 10–20 percent deviation from the averaged distribution.

The framework they developed also allows them to study the impact of projectiles on body armor materials and to predict the response of different fabric weaves upon impact.

ScienceResearchers discover global warming may affect microbe survival Arizona State University researchers have discovered for the first time that temperature determines where key soil microbes can thrive -- microbes that are critical to forming topsoil crusts in arid lands. And of concern, the scientists predict that in as little as 50 years, global warming may push some of these microbes out of their present stronghold in colder US deserts, with unknown consequences to soil fertility and erosion.

Nature CommunicationsKeeping networks under control The need to ensure the proper functioning of the world's many underlying networks -- such as the Internet, power grids and global air transportation -- is increasing. But controlling networks is very difficult. A Northwestern University research team has developed the first broadly applicable computational approach identifying interventions that can both rescue complex networks from the brink of failure and reprogram them to a desired task. The approach to control could have a transformative impact on the complex networks field.

Proceedings of the Royal Society BChapman University unearths data in animal habitat selection that counters current convention Scientists have long presumed that animals settle on breeding territories according to the ideal free model. But settlement data often show that, in fact, animals do not select high quality habitat. Indeed, here we report that young common loons have a striking tendency to settle on breeding lakes that resemble their natal lake in terms of both size and pH.

NatureLocation of upwelling in Earth's mantle discovered to be stable A study published in Nature today shares the discovery that large-scale upwelling within Earth's mantle mostly occurs in only two places: Beneath Africa and the Central Pacific. These upwelling locations have remained remarkably stable over geologic time, despite dramatic reconfigurations of tectonic plate motions and continental locations on the Earth's surface. The study describes a plate tectonic "quadrupole," which defines two points of "net convergence" and two points of "net divergence" of tectonic plate motions.

NatureHow visual attention affects the brain New work at UC Davis shows for the first time how visual attention affects activity in specific brain cells. The paper, published June 26 in the journal Nature, shows that attention increases the efficiency of signaling into the brain's cerebral cortex and boosts the ratio of signal over noise.
