Now, a team led by University of Pennsylvania physicists has used solid-state nanopores to differentiate single-stranded DNA molecules containing sequences of a single repeating base. The study was led by Marija Drndić, an associate professor in the Department of Physics and Astronomy in the School of Arts and Sciences,...

On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. And while QE2 is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of...

Self-folding happens thanks to shape memory polymers that contract when heated. By printing these polymers on one side of a hinged substrate and then heating them, the hinge can be made to bend. The amount of bend is controlled by etching flexible connectors that connect both sides of the hinge, and with enough hinges...

Some parts of the body, like the liver, can regenerate themselves after damage. But others, such as our nervous system, are considered either irreparable or slow to recover, leaving thousands with a lifetime of pain, limited mobility, or even paralysis. Now a team of Tel Aviv University researchers, including Dr. Shimon...
