Web-based courses from Princeton, Stanford, the University of Michigan and the University of Pennsylvania are now available for free from start-up Coursera.
Stanford University electrical engineers have demonstrated a Fantastic Voyage-style wireless chip, driven by magnetic currents, that can travel around inside the human body.
Researchers at California's Stanford University have built and demonstrated an ultrafast nanoscale light-emitting diode (LED) that consumes significantly less power than current laser-based systems.
Reducing soot emissions from diesel engines and other sources could be the fastest, most economical way to slow the melting of Arctic sea ice, researchers say.
Predicting solar flares is going to become increasingly important as the sun hits the most active phase of its 11-year cycle.
Scientists believe they've found an answer to a puzzling gap in the electronic structures of some high-temperature superconductors - and that the answer could be a previously-undiscovered phase of matter.
Stanford researcher Zhenan Bao has created 'super skin' - so sensitive to pressure it can feel a fly touch down, and powered by flexible, stretchable solar cells.
Stanford researchers have created a new wireless technology that allows signals to be sent and received simultaneously on a single channel. The development could double the speed of existing wireless networks.
Carbon Capture and Storage (CCS) underground could trigger earthquakes, a Stanford geophysicist warns.
You always (hopefully) wash your hands after you use the restroom, make sure your countertops are clean, and turn your head whenever you need to sneeze or cough. But that phone sitting in your pocket may be the worst offender of all, and you don't even pay attention to it.
Two US teams have developed artificial skins that are sensitive enough to detect the touch of a butterfly.
A Stanford mechanical engineer is working on an adhesive based on a gecko's sticky foot which would allow people to climb smooth, vertical surfaces.
Researchers at the University of Washington and Stanford University have developed an insectlike robot with hundreds of tiny legs.
Three-quarters of iPhone users love the thing so much that they actually sleep with it, according to a Stanford University study.
