James Serpell of the School of Veterinary Medicine comments on animal behavior resembling love.
PHILADELPHIA -- New research from the University of Pennsylvania is challenging some longtime assumptions about why human beings seek and keep their friends, and it reveals a somewhat darker side to the very nature of friendship itself.
President Amy Gutmann comments on a synthetic-biology process that “has the potential for revolutionizing the treatment of a very deadly and prevalent disease.”
PHILADELPHIA – Three faculty members at the University of Pennsylvania have been named Fellows of the American Association for the Advancement of Science.
They are James C. Alwine, professor of cancer biology; Gideon Dreyfuss, Issac Norris Professor of Biochemistry and Biophysics and a Howard Hughes Medical Institute investigator; and John C. Trueswell, professor of psychology.
Fellows of AAAS are selected for their contributions to science and technology and will be recognized at the Fellows Forum on Feb. 19 during the AAAS Annual Meeting in Washington, D.C.
With the city skyline as a backdrop, it was a beautiful day for a stroll along the shores of the Delaware River: bright sun, low humidity. As well as discarded tires, rusted hulks of unknown machinery, bits of Styrofoam, discarded glass bottles, and even a length of decking material.
If the popularity of the prime-time sitcom “The Big Bang Theory” or the number of television programs produced in the Star Trek franchise (6!) says anything about popular culture, it's that science is not necessarily the enemy of fun. For the skeptics who need proof that science can be dramatic, inspiring and accessible, there is the Penn Science Café, now in its fifth season.
PHILADELPHIA -- A new mathematical model developed by researchers at the University of Pennsylvania has offered even more evidence of the correctness of evolutionary theory.
Herbert Wilf, Penn’s Thomas A. Scott Emeritus Professor of Mathematics, and Warren Ewens, emeritus professor of biology, say their model directly challenges the long-standing contention among some doubters that evolution couldn't have happened because the small changes in species outlined by the theory simply would have taken too much time to be completed.
PHILADELPHIA –- A new instrument designed, built and operated by a collaboration including University of Pennsylvania astronomer James Aguirre and scientists at the California Institute of Technology, the Jet Propulsion Laboratory, the University of Colorado and Japan's Institute of Space and Astronautical Science, is helping to open new views on a vital epoch of star formation in the early universe, using a convenient natural phenomenon called gravitatio
