NASA selects Penn State to lead next-generation planet finder
NASA has selected Penn State to lead a multinational research group that will build a $10-million, cutting-edge instrument to detect planets orbiting stars outside our solar system. When completed in 2019, the instrument will be the centerpiece of a partnership between NASA and the National Science Foundation called the NASA-NSF Exoplanet Observational Research program (NN-EXPLORE).

Mimicking a blood vessel to create a 'bridge' to better medicine and precision treatment
A team of researchers at Lehigh University and the University of Pennsylvania has developed a technique to observe cell to cell interaction at the nanoscale under micro-fluid conditions. They have successfully applied the technique to the study of blood vessel inflammation, a condition that sets the stage for heart disease, the number one cause of death in the US and globally. Their findings have been published in Biomicrofluidics.

Revealing the ion transport at nanoscale
EPFL researchers have shown that a law of physics having to do with electron transport at nanoscale can also be analogously applied to the ion transport. This discovery provides insight into a key aspect of how ion channels function within our living cells.

OU anthropologists reconstruct mitogenomes from prehistoric dental calculus
Using advanced sequencing technologies, University of Oklahoma anthropologists demonstrate that human DNA can be significantly enriched from dental calculus (calcified dental plaque) enabling the reconstruction of whole mitochondrial genomes for maternal ancestry analysis -- an alternative to skeletal remains in ancient DNA investigations of human ancestry.

Researchers develop new method of trapping multiple particles using fluidics
Precise control of an individual particle or molecule is a difficult task. Controlling multiple particles simultaneously is an even more challenging endeavor. Researchers at the University of Illinois have developed a new method that relies on fluid flow to manipulate and assemble multiple particles. This new technique can trap a range of submicron- to micron-sized particles, including single DNA molecules, vesicles, drops or cells.

GOES-R satellite could provide better data for hurricane prediction
The launch of the GOES-R geostationary satellite in Oct. 2016 could herald a new era for predicting hurricanes, according to Penn State researchers. The wealth of information from this new satellite, at time and space scales not previously possible, combined with advanced statistical hurricane prediction models, could enable more accurate predictions in the future.

ASU researcher improves crop performance with new biotechnology
Researchers with Arizona State University's School of Life Sciences have discovered a way to enhance a plant's tolerance to stress, which in turn improves how it uses water and nutrients from the soil. These improvements increase plant biomass and yield. This discovery could be instrumental in agriculture and food security by improving crop sustainability and performance.

Graphene nanoribbons: It's all about the edges
As reported by the journal Nature in its latest issue, researchers from Empa, the Max Planck Institute in Mainz and the Technical University of Dresden have for the first time succeeded in producing graphene nanoribbons with perfect zigzag edges from molecules. Electrons on these zigzag edges exhibit different (and coupled) rotational directions ('spin'). This could make graphene nanoribbons the material of choice for electronics of the future, so-called spintronics.

Newly discovered organic nanowires leave manmade technologies in their dust
A microbial protein fiber discovered by a Michigan State University scientist transports charges at rates high enough to be applied in manmade nanotechnologies. The discovery, featured in the current issue of Scientific Reports, describes the high-speed protein fiber produced by uranium-reducing Geobacter bacteria. The fibers are hair-like protein filaments called 'pili' that have the unique property of transporting charges at speeds of 1 billion electrons per second.
