Journal of Microelectromechanical SystemsNew microfluidic chip can help identify unwanted particles in water and food Virginia Tech researchers developed a new microfabrication technique to develop three-dimensional microfluidic devices in polymers. The devices can be used in the analysis of cells and could prove useful in counterterrorism measures and in water and food safety concerns.

Proceedings of the National Academy of SciencesScientists date prehistoric bacterial invasion still present in today's cells How long ago did bacteria invade the one-celled ancestors of plants and animals to become energy-producing mitochondria and photosynthesizing chloroplasts? Two UC Berkeley doctoral candidates developed a statistical way to analyze the variation in genes common to mitochondria, chloroplasts and the eukaryotic nucleus to more precisely date these events. They found that the cyanobacterial invasion of plants took place millions of years more recently than thought.

NCAR joins massive field campaign to examine summertime air in Southeast Taking part in the largest US air quality field project in decades, the National Center for Atmospheric Research is working with partners to study pollution in the Southeast. The study looks at the impact of chemical reactions occurring between human-related pollution and volatile organic compounds emitted from vegetation.

Nature GeneticsNew research backs theory that genetic 'switches' play big role in human evolution A Cornell University study offers further proof that the divergence of humans from chimpanzees some 4 million to 6 million years ago was profoundly influenced by mutations to DNA sequences that play roles in turning genes on and off.

eLifeComputer modeling technique goes viral at Brandeis Sophisticated computational models and advances in graphical processing units are helping scientists understand the complex interplay between genomic data, virus structure and the formation of the virus' outer "shell" -- critical for replication. "We hope that some of what we are finding will help researchers alter virus assembly, leaving viruses unable to replicate," says postdoctoral fellow Jason Perlmutter, first author of the scientific paper describing the technique, published in the open-access journal eLife.

PLOS ONEAcademics earn street cred with TED Talks but no points from peers, IU research shows TED Talks, the most popular conference and events website in the world with over 1 billion informational videos viewed, provides academics with increased popular exposure but does nothing to boost citations of their work by peers, new research led by Indiana University has found.

Advanced MaterialsPrinting tiny batteries Three-dimensional printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.

Proceedings of the National Academy of SciencesStudy finds the sweet spot -- and the screw-ups -- that make or break environmental collective actions Sustainability programs are a Goldilocks proposition -- some groups are too big, some are too small, and the environment benefits when the size of a group of people working to save it is just right. Scientists at Michigan State University have found a sweet spot -- a group size at which the action is most effective. More importantly, the work revealed how behaviors of group members can pull bad policy up or drag good policy down.

Proceedings of the National Academy of SciencesSubmarine springs reveal how coral reefs respond to ocean acidification Ocean acidification due to rising carbon dioxide levels will reduce the density of coral skeletons, making coral reefs more vulnerable to disruption and erosion, according to a new study of corals growing where submarine springs naturally lower the pH of seawater. The study is the first to show that corals are not able to fully acclimate to low pH conditions in nature.

Nature ChemistryIU chemists produce star-shaped macromolecule that grabs large anions Chemists at Indiana University Bloomington have created a symmetrical, five-sided macrocycle that is easy to synthesize and has characteristics that may help expand the molecular tool box available to researchers in biology, chemistry and materials sciences. The molecule, which the researchers call cyanostar, was developed in the lab of Amar Flood, associate professor in the Department of Chemistry.

Nature GeoscienceNoble gases hitch a ride on hydrous minerals The six noble gases do not normally dissolve into minerals, leaving earth scientists to wonder how they are recycled back into the Earth. Now, researchers at Brown have discovered that the lattice structure of minerals such as amphibole is actually quite capable of dissolving noble gases. Understanding how noble gases cycle from deep within the Earth to the atmosphere and back could help scientists track the cycling of other volatiles like water and carbon.

BioScienceTeaching complete evolutionary stories increases learning Evolution is often thought to be a difficult subject to teach. A novel teaching approach in which undergraduates studied two integrative evolutionary scenarios all the way from the molecular level via the genetic and organismal levels to the population level improved the students' ability to explain and describe evolutionary principles. The results suggest that wider use of such integrated accounts in teaching could improve students' comprehension of evolution.

Journal of the Americal Chemical SocietyNanoparticle opens the door to clean-energy alternatives Cheaper clean-energy technologies could be made possible thanks to a new discovery. An important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth. The research team is led by Raymond Schaak, a professor of chemistry at Penn State University.
