Vanadium dioxide research opens door to new, multifunctional spintronic smart sensors
New research findings open the door to smarter sensors by integrating vanadium dioxide onto a silicon chip and using lasers to make the material magnetic. The advance paves the way for multifunctional spintronic smart sensors for use in military applications and next-generation spintronic devices.

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.

Ballistic transport in graphene suggests new type of electronic device
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature -- a property known as ballistic transport.

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.

Fruit flies -- fermented-fruit connoisseurs -- are relentless party crashers
That fruit fly appearing moments after you poured that first glass of cabernet, has just used a poppy-seed-sized brain to conduct a finely-choreographed search and arrive in time for happy hour.

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.

WPI researchers tackle the challenges of putting robots on the shop floor and in our homes
Researchers at Worcester Polytechnic Institute have received awards through the National Science Foundation's National Robotics Initiative to investigate and overcome fundamental challenges involved with robots working alongside people. Dmitry Berenson will develop algorithms that will permit robots to collaborate with people on small-scale manufacturing operations. Sonia Chernova will draw on the experience of thousands of online "teachers" to learn more about how "everyday people" can teach robots to do simple tasks.

New scientific field looks at the big picture
Big data is changing the field of ecology. The shift is dramatic enough to warrant the creation of an entirely new field: macrosystems ecology. "Ecologists can no longer sample and study just one or even a handful of ecosystems," said Patricia Soranno, Michigan State University professor of fisheries and wildlife and macrosystems ecology pioneer.

Greenland's fastest glacier reaches record speeds
Jakobshavn Isbræ is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. Researchers from the University of Washington and the German Space Agency measured the dramatic speeds of the fast-flowing glacier in 2012 and 2013. The results are published today in The Cryosphere, an open access journal of the European Geosciences Union.

To calculate long-term conservation pay off, factor in people
Paying people to protect their natural environment is a popular conservation tool around the world – but figure out that return on investment, for both people and nature, is a thorny problem, especially since such efforts typically stretch on for years. Reseachers have developed a new way to evaluate and model the long-term effectiveness of conservation investments.

Lemur lovers sync their scents
Mating pairs of lemurs mirror each other's scent-marking behavior and even start to smell alike after they have reproduced. Matched scents are possibly a way to combine territory defenses or to advertise their relationship status to the rest of their group, according to researchers at the Duke Lemur Center. Couples who haven't had kids yet spend the most time scent-marking and investigating each other's odors.

What your company can learn from NASA tragedies
BYU business professor Peter Madsen has been researching how NASA recognizes "near-miss" events ever since the Columbia shuttle was destroyed in flight 11 years ago Saturday. A new study coauthored by Madsen finds recognition of near-misses goes up when leaders emphasize project significance and weigh safety over other goals.

Expanding the range of nature's catalysts for industrial applications
"We've learned to make changes in the stability of the protein. But every protein has a limit; there's nothing you can do to make a protein stable at 500 degrees, for example," said Makhatadze. "So can we somehow make it unfold more slowly by modulating the charge-charge interactions? If you can extend that process, it will function at a high temperature for a longer period of time, and that's beneficial."

Dinosaur fossils from China help Penn researchers describe new 'Titan'
A team led by University of Pennsylvania paleontologists has characterized a new dinosaur based on fossil remains found in northwestern China. The species, a plant-eating sauropod named Yongjinglong datangi, roamed during the Early Cretaceous period, more than 100 million years ago. This sauropod belonged to a group known as Titanosauria, members of which were among the largest living creatures to ever walk the earth.
