President Amy Gutmann is quoted about synthetic biology in her role as chair of the Presidential Commission for the Study of Bioethical Issues.
PHILADELPHIA – Overexpression or hyperactivation of ErbB cell-surface receptors drives the growth of many breast cancers. Drugs, like Herceptin, that block the receptors’ signals halt tumor progression in some patients. However, not all patients’ tumors respond, with some becoming resistant over time. Different drugs that interfere with other steps in the signaling pathway may improve the response of patients, yet little is known about these molecules.
A bid to question the merits of federal funding for social and behavioral science research may be failing to capture the public's attention, even as it signals that larger and more polarizing battles over science, federal policy and money could lie ahead.
Les Shaw and John Trojanowski of the School of Medicine are cited for their contributions to an early diagnosis for Alzheimer’s.
Colleges stand to lose billions of dollars for research, facilities, and other purposes if Congressional leaders hold firm in their pledge to ban earmarks, the spending that individual members direct to their home states and favorite projects outside of the competitive processes.
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.
