Record-breaking high-energy particles detected by telescope buried in Antarctic

5/17/13

A massive telescope buried in the Antarctic ice has detected 28 extremely high-energy neutrinos -- elementary particles that likely originate outside our solar system. Two of these neutrinos had energies many thousands of times higher than the highest-energy neutrino that any man-made particle accelerator has ever produced, according to a team of IceCube Neutrino Observatory researchers that includes Penn State scientists. These new record-breaking neutrinos had energies greater than 1,000,000,000,000,000 volts or, as the scientists say, 1 peta-electron volt (PeV).

Students' diet and physical activity improve with parent communications

5/16/13

College students eat more fruits and vegetables and exercise more on days when they communicate more with their parents, according to researchers at Penn State.

"Only a third of college students consumes a diet that is consistent with national recommendations," said Meg Small, research associate in the Prevention Research Center for the Promotion of Human Development.

GridSTAR Net Zero Energy Demonstration Project under way at The Navy Yard

5/13/13

A powerful collaboration of researchers, manufacturers and economic development officials are embarking on a groundbreaking demonstration project for smart-grid, net zero energy buildings called the GridSTAR Center — a Smart Energy Campus initiative at The Navy Yard in Philadelphia. Spearheaded by Penn State with support from the U.S. Department of Energy, Commonwealth of Pennsylvania and Philadelphia Industrial Development Corporation (PIDC), the GridSTAR Net Zero Energy Demonstration Structure is the first phase of the GridSTAR Center.

Obese students' childbearing risk varies with high school obesity rates

5/9/13

For young women in high school, the risk of childbearing may depend on the prevalence of obesity in their schools, according to sociologists, who found that as the prevalence of obesity rises in a school, so do the odds of obese high school students bearing children.

The Mexican Children of Immigrants Program: Interpreting the numbers

5/8/13

Language barriers, fear of deportation, and community prejudice are problems often faced by Mexican immigrants that contribute to dramatic disparities in health and well-being between immigrants and the native-born U.S. population. These problems may be compounded by family and community characteristics, making it especially difficult for the children of immigrants to receive the basic services needed to promote a healthy future. Such complexities are the focus of a three-pronged program of investigation by a research team at Penn State's Penn State's Population Research Institute (PRI).

Whole walnuts and their extracted oil improve cardiovascular disease risk

5/8/13

Consumption of whole walnuts or their extracted oil can reduce cardiovascular risk through a mechanism other than simply lowering cholesterol, according to a team of Penn State, Tufts University and University of Pennsylvania researchers.

Probing Question: Do women dominate the field of forensic science?

5/7/13

Exhuming corpses, analyzing bloodstained clothing, collecting "crime scene insects" (yes, maggots)...these are some of the grittier realities of life as a forensic scientist. Yet defying the stereotype that females tend to be squeamish about such things, an entire generation of young women have become entranced by the profession. In fact, they've pursued this career in such numbers that—unlike almost every other scientific discipline—one could argue that the booming field of forensic science is a female domain.

AMON: An Eye on the Universe

5/6/13

AMON stands for Astrophysical Multimessenger Observatory Network. Its mission is to form a network of high-energy observatories across the globe that will search for previously unseen astrophysical signals and send alerts to more traditional telescopes in order to corroborate the possible celestial events.

Bonding with your virtual self may alter your actual perceptions

5/2/13

When people create and modify their virtual reality avatars, the hardships faced by their alter egos can influence how they perceive virtual environments, according to researchers presenting their findings at 2013 Annual Conference on Human Factors in Computing Systems in Paris today (May 2).

Scientists make strides toward restoring bighorn sheep in the American West

5/2/13

As pneumonia continues to limit recovery of the once nearly extinct bighorn sheep population in the western United States, a research team including scientists from Penn State’s Huck Institutes of the Life Sciences has made key discoveries that lead to a better understanding of the disease and how it might be more effectively controlled.

People may welcome talking tissue boxes and other smart objects

5/1/13

Just as people have embraced computers and smart phones, they may also give their blessing to talking tissue boxes and other smart objects, according to Penn State researchers. "Smart objects will become more and more a part of our daily lives," said S. Shyam Sundar, Distinguished Professor of Communications and co-director of the Media Effects Research Laboratory.

Leadership emerges spontaneously during games

4/29/13

Video game and augmented-reality game players can spontaneously build virtual teams and leadership structures without special tools or guidance, according to researchers. Players in a game that mixed real and online worlds organized and operated in teams that resembled a military organization.

Changing cellulose-forming process may tap plants' biofuel potential

4/26/13

Changing the way a plant forms cellulose may lead to more efficient, less expensive biofuel production, according to Penn State engineers. "What every biofuel manufacturer wants to do is to get to the sugars," said Jeffrey Catchmark, associate professor of agricultural and biological engineering. "But the structure of cellulose itself can be an obstacle."

New research center tackles concussions

4/25/13

Penn State's Center for Sport Concussion Research and Service, in Rec Hall, has two main goals: to advance research in sport-related concussions and to provide services to local collegiate and child athletes by performing baseline assessments, which can help diagnose a concussion. The center is the first in its field to use virtual-reality technology to allow researchers to document athletes' cognitive and motor abilities.

Research shows oral supplement increases body's storage of antioxidant

4/22/13

Oral supplementation of glutathione is effective in increasing the body’s stores of the antioxidant, according to Penn State College of Medicine researchers. Glutathione is involved in protecting cells and tissues from oxidants and other toxins.

Biting the Plant that Feeds You

She's part pilgrim and part vampire, purplish black and pear-shaped. Moments after her April birth, the aphid creeps along the smooth witch hazel leaf until she finds a suitable intersection of veins. She thrusts her needle mouth into the junction and begins to feed, sucking the sweet sap from the plant.

Benner's Hill on the Gettysburg Battlefied

Guide adds new voices to history of Gettysburg battle

5/15/13

For three days in July 1863, thousands of Gettysburg civilians and tens of thousands of soldiers were caught up in a battle that left often conflicting data and anecdotes. This makes writing about the Battle of Gettysburg both a dream and a nightmare for Civil War historians, according to a Penn State researcher.
