Confirmed: Stress Gradient Hypothesis: How Plant Communities Endure Stress

The Stress Gradient Hypothesis holds that as stress increases in an ecosystem, mutually supportive interactions become more significant and negative interactions, such as competition, become less so. The idea has been hotly debated but is now backed by a review of hundreds of studies co-authored in Ecology Letters by Mark Bertness, professor of biology at Brown, who first formally proposed the hypothesis in 1994. The time has come, he said, to test its application and predictive value. (more…)

Survey: More Freshmen than Ever Say They Go to College to Get Better Jobs, Make More Money

The current economic situation in the United States has a major influence on first-year students’ decisions about which college to attend and is reflected in their reasons for pursuing higher education, according to the CIRP Freshman Survey, UCLA’s annual survey of the nation’s entering students at four-year colleges and universities.

The survey, part of the Cooperative Institutional Research Program (CIRP), is administered nationally by the Higher Education Research Institute (HERI) at UCLA’s Graduate School of Education and Information Studies.

Two out of three first-year students (66.6 percent) surveyed said they believe current economic conditions significantly affected their choice of college, up from 62.1 percent just two years earlier, when the question was first asked. (more…)

Solar Fuel Success

UD-developed solar reactor can produce solar hydrogen, but how much?

Last spring University of Delaware doctoral candidate Erik Koepf and research associate Michael Giuliano spent two months in Switzerland testing a novel solar reactor Koepf developed to produce hydrogen from sunlight.

Eight weeks of sophisticated testing at temperatures up to 1,200 degrees Celsius revealed that the reactor’s mechanical, electrical and thermal systems worked just as Koepf had predicted. (more…)

comScore Study Highlights Digital Wallet Market Potential and Current Adoption Barriers

New Report “Digital Wallet Road Map 2013” Offers Data, Insights and Strategies for Overcoming Barriers on Awareness, Understanding of Benefits, Availability and Security Concerns

RESTON, VA, February 4, 2012 – comScore, Inc., a leader in measuring the digital world, today released the Digital Wallet Road comScoreMap 2013, a study which measures consumer awareness, perceptions and intent to use current digital wallet offerings. The study found that digital wallets, which store a virtual copy of the contents of a consumer’s physical wallet to facilitate online or offline retail transactions, only had awareness among 51 percent of U.S. consumers for wallets other than PayPal.

“Digital wallets represent an innovative technology that has not yet reached critical mass among consumers due to a variety of factors, including low awareness and a muddied understanding of their benefits,” said Andrea Jacobs, comScore Payments Practice Leader. “This study delves deeply into the mindset of consumers with respect to their potential use of digital wallets, in addition to helping size the market opportunity. The study also provides guidance on how digital wallet providers, marketers, developers and retailers can contribute to growing adoption of this technology.” (more…)

Small Asteroid to Whiz Past Earth Safely

The small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15, so close that it will pass inside the ring of geosynchronous weather and communications satellites. NASA’s Near-Earth Object Program Office can accurately predict the asteroid’s path with the observations obtained, and it is therefore known that there is no chance that the asteroid might be on a collision course with Earth. Nevertheless, the flyby will provide a unique opportunity for researchers to study a near-Earth object up close. (more…)

Study: Alternate Walking and Running to Save Energy, Maintain Endurance

COLUMBUS, Ohio — Forget “slow and steady wins the race.” A new study shows that, at least sometimes, the best way to conserve energy and reach your destination on time is to alternate between walking and running—whether your goal is the bus stop or a marathon finish line.

In the January 30, 2013 issue of the Journal of the Royal Society Interface, researchers examined how people budget their time as they travel on foot to reach a destination at a particular appointed time. The study found that when people have neither too much time nor too little time to reach their destination, they naturally switch back and forth between walking and running, which turns out to be the best strategy for saving energy.
