Recent advances in nanotechnology and engineering are allowing scientists to design microscopic devices with nearly atomic precision. One promising application of this accuracy is to improve the way drugs are delivered to the areas in the human body where they are needed most.

PHILADELPHIA — Targeted drug delivery is one of the more enticing applications of nanotechnology; by designing pharmaceuticals on an atomic scale, engineers hope to get them attacking diseases with newfound precision and efficiency.

Human beings have been influencing the evolution of the pig for more than 10,000 years. Descended from the hairy, ornery wild boar, modern pigs’ physical forms and everyday lives are increasingly molded by human technology.

Most people take gravity for granted. But for University of Pennsylvania astrophysicist Bhuvnesh Jain, the nature of gravity is the question of a lifetime.

Increasing the nation’s proficiency in STEM fields—science, technology, engineering and math—is one of President Obama’s top educational goals. He has made it clear that more bright young students should be entering the pipeline to become working scientists and engineers, and has called on educational institutions to help meet this challenge.    

KENNETT SQUARE — Horses weigh more than half a ton and can sleep standing up, so as surgical patients, they can’t recuperate in a cushy bed.

PHILADELPHIA -- Steve Fluharty, the University of Pennsylvania’s senior vice provost for research, is participating in a new congressional program that will highlight federally funded science projects.

On Friday May 4, a half-century of groundbreaking science and education will be honored at the Laboratory for Research on the Structure of Matter’s (LRSM) 50th Anniversary Symposium.

PHILADELPHIA — Having a virtual copy of a patient’s blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.

PHILADELPHIA — The University of Pennsylvania and Bryn Mawr College are launching a new program that will allow undergraduates at Bryn Mawr to gain early admission into a master’s degree program offered by Penn’s School of Engineering and Applied Science.  The arrangement effe
