Dartmouth researchers test first 'smart spaces' using light to send data
One of the problems in the high-tech field of visible light communication -- or using light to send data wirelessly -- is decidedly low tech: The data transmission stops whenever the light is blocked by people's movements, shadows or other obstacles. But Dartmouth researchers are experimenting with the first 'smart spaces' that feature an interplay of algorithms, ceiling-mounted LEDs and light sensors embedded in floors and in smart devices, enabling a continuous flow of data wirelessly.

Stock market models help NYU researchers predict animal behavior
Modeling used to forecast fluctuations in the stock market has been discovered to predict aspects of animal behavior. The movement of zebrafish when mapped is very similar to the stochastic jump process, a mathematical model used by financial engineers. The model could improve the effectiveness of experiments, minimize the number of fish used, and allow researchers to make better use of their data following experiments.

Inhabit(ants) of New York City: High diversity underfoot in urban environments
Cities have more species diversity than you'd expect. A study of ants in Manhattan found not only a wide range of species, but also significant differences in the levels of biodiversity in different urban areas.

Do homing pigeons navigate with gyroscope in brain?
No one knows how homing pigeons do it, but now a team of Swiss and South African scientists have discovered that the bird's navigation is affected by disturbances in gravity, suggesting that they navigate using a gravity map and that they may carry an internal gyroscope to guide them home.

UH receives $1.5 million grant to prepare future cybersecurity workers
With breaches in data on the rise, cybersecurity is a growing concern. The University of Houston has been awarded a $1.5 million CyberCorps grant from the National Science Foundation to train students in this increasingly important area of national security. The congressionally mandated CyberCorps Scholarship for Service program is aimed at increasing and strengthening the cadre of information assurance professionals who protect the government's critical information infrastructure.

Bending -- but not breaking -- in search of new materials
Researchers at Drexel University and Dalian University of Technology in China have chemically engineered a new, electrically conductive nanomaterial that is flexible enough to fold, but strong enough to support many times its own weight. They believe it can be used to improve electrical energy storage, water filtration and radiofrequency shielding in technology from portable electronics to coaxial cables.

Scientists build a better eye on our world
Science begins with observation, and defining moments in scientific progress followed the introduction of new ways to observe the world, from microscopes and telescopes to X-rays and MRIs. The Electronic Visualization Laboratory at the University of Illinois at Chicago has been awarded a $3 million National Science Foundation grant to develop an extraordinary new camera -- really an array of dozens of video cameras -- that can capture images in 360 degrees and three dimensions.

MU researchers offer first analysis of new human glucose disorder
Glycogen storage disorders are metabolic conditions that manifest in the first years of life. This inability to process and store glucose can be difficult to diagnose. Now, researchers at the University of Missouri who have studied enzymes involved in metabolism of bacteria have cataloged the effects of abnormal enzymes responsible for one type of this disorder in humans. Their work could help with patient prognosis and in developing therapeutic options for this glycogen storage disease.

Some plants regenerate by duplicating their DNA
When munched by grazing animals -- or mauled by scientists in the lab -- some herbaceous plants overcompensate -- producing more plant matter and becoming more fertile than they otherwise would. Scientists say they now know how these plants accomplish this feat of regeneration.

Supercomputing beyond genealogy reveals surprising European ancestors
Most Europeans today derive from three distinct populations, as evidenced by sequenced genomes of nine ancient remains and 2,345 contemporary humans. Genomic analysis of modern and ancient DNA, combined with archeological evidence is revealing new complexity in human history. Scientists used the NSF XSEDE Stampede supercomputer of the Texas Advanced Computing Center to model and compare genomic data of ancient and modern Europeans.

Wireless devices used by casual pilots vulnerable to hacking, computer scientists find
A new class of apps and wireless devices used by private pilots during flights for everything from GPS information to data about nearby aircraft is vulnerable to a wide range of security attacks, which in some scenarios could lead to catastrophic outcomes, according to computer scientists at the University of California, San Diego and Johns Hopkins University. They presented their findings Nov. 5 at the 21st ACM Conference on Computer and Communications Security in Scottsdale, Ariz.

The cat's meow: Genome reveals clues to domestication
Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome by researchers at Washington University School of Medicine in St. Louis reveals some surprising clues. The research appears Nov. 10 in the Proceedings of the National Academy of Sciences Early Edition.

Instead of carbon dioxide being like a blanket that slowly warms the planet, after about a decade most warming comes from melting ice and snow and a more moist atmosphere, which both cause the Earth to absorb more shortwave radiation from the sun.
