PHILADELPHIA –- Researchers at the University of Pennsylvania, the University of Wisconsin-Madison and IBM Research-Zürich have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more wear-resistant at the nanoscale than silicon.
Building Fit Minds Under Stress: Penn Neuroscientists Examine the Protective Effects of Mindfulness Training
PHILADELPHIA –- A University of Pennsylvania-led study in which training was provided to a high-stress U.S. military group preparing for deployment to Iraq has demonstrated a positive link between mindfulness training, or MT, and improvements in mood and working memory. Mindfulness is the ability to be aware and attentive of the present moment without emotional reactivity or volatility.
PHILADELPHIA –- A pair of University of Pennsylvania seniors and a Penn alumna are among 29 Gates Cambridge Scholarship winners from the United States. They will begin their graduate studies at the University of Cambridge in England in October. They bring the number of Penn winners to 20.
The scholarship winners selected are:
University of Pennsylvania Material Scientists Turn Light Into Electrical Current Using a Golden Nanoscale System
PHILADELPHIA –- Material scientists at the Nano/Bio Interface Center of the University of Pennsylvania have demonstrated the transduction of optical radiation to electrical current in a molecular circuit. The system, an array of nano-sized molecules of gold, respond to electromagnetic waves by creating surface plasmons that induce and project electrical current across molecules, similar to that of photovoltaic solar cells.
PHILADELPHIA –- Biologists at the University of Pennsylvania studying oocytes in mice, the immature egg cells necessary for sexual reproduction, have demonstrated an unusual behavior in microRNA, or miRNA, activity that may be the first event in reprogramming the differentiated oocyte into pluripotent blastomeres of the embryo. MicroRNAs are a member of the family of small RNAs, the so-called dark matter of the biological world.
PHILADELPHIA –- Psychologists at the University of Pennsylvania and the University of Memphis have released a new study on linguistic evolution that challenges the prominent hypothesis for why languages differ throughout the world.
The study argues that human languages may adapt more like biological organisms than previously thought and that the more common and popular the language, the simpler its construction to facilitate its survival.
Penn Biologists Explain How Organisms Can Tolerate Mutations, Yet Adapt and Survive Environmental Change
PHILADELPHIA –- Biologists at the University of Pennsylvania studying the processes of evolution appear to have resolved a longstanding conundrum: How can organisms be robust against the effects of mutations yet simultaneously adaptable when the environment changes?
PHILADELPHIA –- Skirkanich Hall, home to the Bioengineering Department in the University of Pennsylvania’s School of Engineering and Applied Science, has received the 2010 Institute Honor Award for Architecture from the American Institute of Architects.
Spikes in News Coverage of HPV, Cervical Cancer Linked to Increased Knowledge, but Important Information Omitted
PHILADELPHIA -– In the months surrounding the U.S. Food and Drug Administration’s approval of the human papillomavirus vaccine, an increase in the volume of news coverage was associated with changes in the public’s knowledge about HPV and cervical cancer. However, a new study reveals that many news stories were missing important information, including the sexually transmitted nature of the disease.
