Security in a networked world

03/02/11 — Nearly two billion people-more than the population of China-now use the Internet. With its vast capacity for communication and information, the web has become a powerful tool for transformative change: from new financial services and poverty alleviation to political change, as we are seeing in North Africa and the Arabian Peninsula.

Superstructure rising

03/02/11 — Not long after the Loma Prieta quake struck, Marwan Nader (M.S'89, Ph.D'92 CE) gazed at the hole in the Bay Bridge as he stood a safe distance away, part of a Berkeley team inspecting the damage. Twenty-two years later, he's still standing on the bridge, so to speak. As lead design engineer of the self-anchored suspension (SAS) bridge, he is responsible for the standout architectural feature of the new portion of the bridge that will replace the old eastern span.

The laser whisperer

03/02/11 — A research team led by Xiang Zhang, professor of mechanical engineering and faculty scientist at Lawrence Berkeley Laboratory, has taken inspiration from the phenomena of whispering galleries - such as the U.S. Capitol's Statuary Hall or Grand Central Terminal in New York - and their remarkable acoustical features to achieve a major scientific breakthrough in the use of plasmon lasers. By creating a technique to bounce surface plasmons inside of a nanosquare device, much in the way sound waves reflect back and forth in a whispering gallery, the team was able to operate plasmon lasers at room temperature, overcoming what had been a major barrier to practical utilization of the technology.

A high-stepping boot camp

03/02/11 — They slept in yurts and went six days with virtually no cell phones or Internet service. But for 59 Berkeley Engineering undergraduates, spending their semester break at a woodsy Sonoma County retreat was the journey of a lifetime. The students were participants in Berkeley Engineering's first-ever LeaderShape Institute, a national program that trains young people to lead with integrity and make significant contributions to better the world. They returned to Berkeley focused, energized-and ready to take on new challenges. Voicing the sentiments of many, Paul Zarate, a second-year mechanical engineering student, says, “It was for sure worth missing a week out of your winter break. It was awesome.”

Engineers applaud as Watson beats humans in Jeopardy!

02/17/11 New Scientist — In the battle between human and machine, our silicon opponents just notched up another victory. The new digital champ is Watson, a supercomputer designed by IBM to play Jeopardy!, a US quiz game famous for its strangely worded clues. The 200 or so engineers who watched the final show in an auditorium at UC Berkeley revealed in a show of hands that around three-quarters of the audience were rooting for Watson. "It's fun to see a computer beat a human," said one student. IBM was represented by Jean Paul Jacob, a computer scientist who spent 42 years at the company and who also holds a position at CITRIS at Berkeley.

How to measure an oil spill

02/02/11 — When oil was flowing from BP's broken well at the bottom of the Gulf of Mexico last spring, the company estimated the flow rate at about 1,000 barrels a day. But news outlets wanted an independent estimate. Could Ömer Savaş, an expert in fluid mechanics and turbulent flows, help? Soon Savaş became involved in a national effort to establish the “official” flow rate, a number that would dictate not only the level of resources assigned to the cleanup but also its legal ramifications once the emergency had passed.
