Big data sets are important tools of modern science. Mining for correlations between millions of pieces of information can reveal vital relationships or predict future outcomes, such as risk factors for a disease or structures of new chemical compounds.
By encoding information in photons via their spin, “photonic” computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin of electrons, rather than just their quantity, could make “spintronic” computers with similar advantages.
A scar might be a reminder of an accident or surgery, but the fibrous tissue that makes up a scar also forms after a heart attack and arises in solid tumors as well as in chronic diseases such as liver cirrhosis and muscular dystrophy. Implanted medical devices and materials are similarly surrounded by fibrous capsules that impede their function.

Nature versus nurture is an age-old question in biology, centering on whether a given trait is determined by an organism’s genes or by its environment. Most times the answer is “both,” but research at the University of Pennsylvania has found one trait in particular that is not easily described by either.
Investigators at a new University of Pennsylvania research center will focus on key physical principles that underpin cancer’s development and growth.
Penn Electric Racing has taken home top honors at an international competition.
Despite their ubiquity in consumer electronics, rare-earth metals are, as their name suggests, hard to come by. Mining and purifying them is an expensive, labor-intensive and ecologically devastating process.
Picking things up and putting them down is a mainstay of any kind of manufacturing, but fingers, human or robotic, are not always best for the task at hand.
For diabetics, a quick prick of the finger can give information about their blood glucose levels, guiding them in whether to have a snack or inject a dose of insulin. Point-of-care glucose meters, or glucometers, are also used in the veterinary world to monitor cats and dogs with diabetes or pets hospitalized for other reasons.
