Economic Forecast
*No silver bullet but hope for economy remains, experts tell audience at UD*
Analogies abounded at the 2012 Economic Forecast, where speakers compared monetary policy to turnpike driving, fiscal policy to an empty toolbox and investing to “finding the least worst house on an unstable block.”
Charles I. Plosser, president and CEO of the Philadelphia Federal Reserve, was one of three featured speakers at the annual event, which was sponsored by Lyons Companies and the University of Delaware’s Center for Economic Education and Entrepreneurship (CEEE) and held Tuesday, Feb. 14, at UD’s Clayton Hall.

NASA Map Sees Earth’s Trees in a New Light
PASADENA, Calif. – A NASA-led science team has created an accurate, high-resolution map of the height of Earth’s forests. The map will help scientists better understand the role forests play in climate change and how their heights influence wildlife habitats within them, while also helping them quantify the carbon stored in Earth’s vegetation.
Scientists from NASA’s Jet Propulsion Laboratory, Pasadena, Calif.; the University of Maryland, College Park; and Woods Hole Research Center, Falmouth, Mass., created the map using 2.5 million carefully screened, globally distributed laser pulse measurements from space. The light detection and ranging (lidar) data were collected in 2005 by the Geoscience Laser Altimeter System instrument on NASA’s Ice, Cloud and land Elevation Satellite (ICESat). (more…)
Teaching Science to The Religious? Focus on How Theories Develop
Brown biology Professor Ken Miller understands that most students are religious. He is too. The way to teach science to religious students is to show how scientific ideas come to be, he says. Students can learn that religious people engage in scientific explorations of nature, and that theories are based on observation and logic, not some anti-religious agenda.
Vicious, winner-take-all competition in nature is an essential pillar of evolutionary theory, but it frequently describes the mindset people have about how, or whether, to teach the subject. Religious students sometimes come to class thinking that science and religion are in deliberate opposition, like two lionesses fighting over a kill. When Brown University biologist and practicing Catholic Kenneth Miller teaches evolution, he also teaches that such a zero-sum mindset just isn’t warranted. (more…)
Study: Military Death Sentence More Likely For Minorities
EAST LANSING, Mich. — Skin color plays a role in deciding whether to execute military criminals, according to a new study by a Michigan State University law professor who found minorities in the military are twice as likely as whites to be sentenced to death. (more…)
UCLA Engineers Create Tandem Polymer Solar Cells That Set Record For Energy-Conversion
In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential. Organic polymers can be produced in high volumes at low cost, resulting in photovoltaic devices that are cheap, lightweight and flexible.
In the last few years, much work has been done to improve the efficiency with which these devices convert sunlight into power, including the development of new materials, device structures and processing techniques. (more…)
At Yale, Quantum Computing is a (qu)bit Closer to Reality
Physicists at Yale University have taken another significant step in the development of quantum computing, a new frontier in computing that promises exponentially faster information processing than the most sophisticated computers of today.
In research published online this month in the journal Nature, the Yale physicists demonstrate the most basic form of quantum error correction — a way to compensate for quantum computing’s intrinsic susceptibility to errors. Developing technology to correct these errors on the fly is a necessary step for fully realizing quantum computers. (more…)
Cellphone Use Linked to Selfish Behavior in UMD Study
COLLEGE PARK, Md. – Though cellphones are usually considered devices that connect people, they may make users less socially minded, finds a recent study from the University of Maryland’s Robert H. Smith School of Business.
Marketing professors Anastasiya Pocheptsova and Rosellina Ferraro, with graduate student, Ajay T. Abraham, conducted a series of experiments on test groups of cellphone users. The findings appear in their working paper, The Effect of Mobile Phone Use on Prosocial Behavior. (more…)
