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.

There’s a good reason your doctor asks for a urine sample at your annual checkup. A simple, color-changing paper test, dipped into the specimen, can measure levels of glucose, blood, protein and other chemicals, which in turn can indicate evidence of kidney disease, diabetes, urinary tract infections and even signs of bladder cancer.

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
