New Boson Discovered at CERN
By combining the work of two research teams, ATLAS and CMS, CERN has announced the discovery of a new boson with a mass between 125-126 GeV/c2 at a confidence level that leaves the chance of random events faking the discovery at less than 1 in 10 million.

Drndic & Shepard Nature Methods: New Integrated Platform Paves the Way to Cheaper, Faster DNA Sequencing
Penn Physics and Engineering researchers measure single molecules faster and with less error than can be achieved with commercial instruments. "We combined the most sensitive electronics with the most sensitive solid-state nanopores," says Drndic.

Penn Physicists’ New Manufacturing Technique Means Higher Quality Nanotube Devices
Major advances in materials science and nanotechnology promise to revolutionize electronic devices with unprecedented strength and conductivity, but those promises can’t be fulfilled if the devices can’t be consistently manufactured. Working on the nanoscale means the effects of even the smallest imperfections are magnified, but University of Pennsylvania physicists have developed a new printing technique that is effective at making carbon nanotube devices with minimal impurities.
