In work that could help inform policies for government surveillance and consumer data privacy, researchers show that telephone metadata can reveal a surprising amount of personal detail.

Most people might not give telephone metadata – the numbers you dial, the length of your calls – a second thought. Some government officials probably view it as similarly trivial, which is why this information can be obtained without a warrant.

It is difficult to imagine that 50 years ago, practically no one wanted to fund the development of a Global Positioning System (GPS). Not only were governments uninterested in funding such a project, they didn’t consider it useful.

A team of engineers obtain a first look inside phase-changing nanoparticles and find that their structure significantly influences performance.
Stanford engineers studying the structures of phase-changing nanoparticles have found that shape matters. Materials composed of cubes and pyramids, for instance, may yield more efficient batteries than those made of icosahedrons which are 20-sided polyhedrons. | Image courtesy Dionne Group

When Stanford's autonomous car Shelley nears speeds of 120 mph as it tears around a racetrack without a driver, observers' natural inclinations are to exchange high-fives or simply mouth, "wow."
