Bats do it, dolphins do it. Now humans can do it too. July 6, 2015:

BERKELEY — University of California, Berkeley, physicists have used graphene to build lightweight ultrasonic loudspeakers and microphones, enabling people to mimic bats or dolphins’ ability to use sound to communicate and gauge the distance and speed of objects around them. More practically, the wireless ultrasound devices complement standard radio transmission using electromagnetic waves in areas where radio is impractical, such […]

Rethinking the use of Social Security numbers

Rethinking the use of Social Security numbers June 5, 2015:

Cyberattacks — roughly two every day in the United States — have raised questions about the use of our Social Security numbers as universal identifiers. If it’s not possible to stop using them, what else can people do to fend off identity thieves? Berkeley privacy expert Chris Hoofnagle, among others, offers some ideas.

Economists and statisticians from across the UC Berkeley campus will soon be able to collaborate more easily, via the newly formed Consortium for Data Analytics in Risk, with financial-industry experts on advanced data-intensive techniques for managing and easing economic and financial risk.

Electric vehicle batteries last longer than previously thought

Electric vehicle batteries last longer than previously thought March 30, 2015:

Scott Moura, UC Berkeley assistant professor of civil and environmental engineering, has co-authored a study with Berkeley Lab colleagues that may alleviate the concerns of battery life in electric vehicles. After analyzing real-world driving patterns, the researchers found that batteries that have lost 20 percent of their originally rated energy storage capacity can still meet the daily travel needs of more than 85 percent of U.S. drivers.
