The evolution of adaptations for life on land have long puzzled biologists – are feathers descendents of dinosaur scales, how did arms and legs evolve from fins, and from what ancient fish organ did the lung evolve?

The drug topiramate, typically used to treat epilepsy and more recently weight loss, may also help people addicted to both cocaine and alcohol use less cocaine, particularly heavy users, researchers in the department of Psychiatry at Penn Medicine report in a new study published in Drug and

Physicist Charlie Johnson connects the biological to the digital, using graphene and carbon nanotubes to turn chemical interactions into electrical signals. Johnson will explain how attaching biological structures, such as antibodies, to these flat or rolled-up lattices of carbon atoms has enabled him and his colleagues to build new kinds of sensors, detecting things like Lyme disease bacteria.

The trajectory of amyloid plaque buildup—clumps of abnormal proteins in the brain linked to Alzheimer’s disease—may serve as a more powerful biomarker for early detection of cognitive decline rather than using the total amount to gauge risk, researchers from Penn Medicine’s Department of Radiology suggest in a new study published online July 1

“Human computing power” harnessed from ordinary citizens across the world has the potential to accelerate the pace of health care research of all kinds, a team from the Perelman School of Medicine at the University of Pennsylvania, writes in a new review published online in the Journal of General Internal Medicine. 

Harvey L. Nisenbaum, MD, FACR, FAIUM, FSRU, chairman, Department of Medical Imaging at Penn Presbyterian Medical Center was named President-Elect (2013-2015) of the World Federation for Ultrasound in Medicine and Biology at the WFUMB World Congress 2013 Meeting, May 2-5, 2013 in Sao Paulo, Brazil.

Researchers in the Perelman School of Medicine at the University of Pennsylvania found that, across a variety of neurodegenerative diseases, cerebrovascular disease affecting circulation of blood in the brain was significantly associated with dementia.

Patients with low socioeconomic status use emergency and hospital care more often than primary care because they believe hospital care is more affordable and convenient, and of better quality than care provided by primary care physicians, according to the results of a new study from researchers at the Perelman School of Medicine at the University of Pennsylv

Neurodegenerative diseases are not all alike. Two individuals suffering from the same disease may experience very different age of onset, symptoms, severity, and constellation of impairments, as well as different rates of disease progression.

Mariell Jessup, MD, professor of Medicine, associate chief, Clinical Affairs, Division of Cardiovascular Medicine, and medical director of the Penn Medicine Heart and Vascular Center, has become the president of the American Heart Association (AHA). Her term begins July 1, 2013.
