Damage control

07/12/10 California Magazine — In 1985, Jack Moehle, Professor of Civil and Environmental Engineering at Berkeley, traveled to Chile to sort through the rubble left in the wake of the devastating 7.8 magnitude earthquake that rocked the coast. He was one of a number of Californian and Chilean engineers who collaborated to study the structural damage. As a result of their research, both the United States and Chile modified their building codes to nearly identical standards. This year, Moehle and a Berkeley reconnaissance team returned to Chile in the aftermath of the 8.8 magnitude shaker on February 27. Because of the similarity in building codes, the sort of damage Moehle has found could predict how California would fare in a major quake.

Nanosized light mill drives micro-sized disk

07/05/10 Berkeley Lab — Engineers at Lawrence Berkeley National Laboratory and the University of California Berkeley have created the first nanosized light mill motor whose rotational speed and direction can be controlled by tuning the frequency of the incident light waves. This new light mill opens the door to a broad range of valuable applications, including a new generation of nanoelectromechanical systems (NEMS), nanoscale solar light harvesters, and bots that can perform in vivo manipulations of DNA and other biological molecules.

Explaining the equation behind the oil spill disaster

07/03/10 Science News — Catastrophes come in all shapes and sizes, but some basic causative principles underlie most of them. Robert Bea, an engineer at the University of California, Berkeley, has studied system failures from space shuttle explosions to levee breaks during Hurricane Katrina -- but as a former oil rig worker he is most familiar with drilling disasters. Bea has thus assumed a key role in analyzing the response to the Deepwater Horizon spill in the Gulf of Mexico. He spoke with Science News about why the spill could have been foreseen.

06/03/10 — On May 16, we sent more than 1,200 newly minted engineers into the world to invent stronger bridges, faster computers, greener energy, safer medicines and a host of other societal solutions. Our commencement ceremony in the Greek Theatre made me especially proud of our Berkeley engineers. They offer a rare blend of deep technical expertise and broad mastery of the human skills necessary to make a genuine impact.

Thermoelectrics: A matter of material

06/03/10 — Waste heat: It's when heat produced in a combustive process goes unused, dissipating into the air or water. Automobiles, industrial facilities and power plants all produce waste heat, and a lot of it. A holy grail awaits anyone who can improve the current fossil fuel system. One estimate places the worldwide waste heat recovery market at one trillion dollars, with the potential to offset as much as 500 million metric tons of carbon per year. What's the magic solution? Some Berkeley engineers believe the answer lies not in a sophisticated device, but in materials: specifically, finding a new material with spectacular thermoelectric properties that can efficiently and economically convert heat into electricity.

Researchers empower robot to fold towels

06/03/10 — Who wouldn't want a robot that could make your bed or do the laundry? A team of Berkeley researchers has brought us one important step closer by, for the first time, enabling an autonomous robot to reliably fold piles of previously unseen towels. Robots that can do things like assembling cars have been around for decades. The towel-folding robot, however, is doing something very new, according to the researchers, doctoral student Jeremy Maitin-Shepard and assistant professor Pieter Abbeel, both of UC Berkeley's Department of Electrical Engineering and Computer Sciences.

Toys, games, explosions! Engineers reach out to school kids

06/03/10 — BEAM, Berkeley Engineers and Mentors, got its start last year when a group of engineering students saw a need to organize science and engineering outreach to local schools. For years, engineering societies have sent members to K–12 schools to teach concepts and mentor younger students to meet their community service goals. But coordination overlapped or fell short, and lesson plans and best practices often disappeared or got lost in forgotten files. With Berkeley's characteristic can-do spirit, a group of society officers took the initiative to start a club that would remedy the problem.

Synthetic-biology competition launches

06/02/10 Nature — A Japanese competition launched last week is aiming to help the burgeoning science of synthetic biology to deliver commercial applications.

Apple: Products vs. stock

05/27/10 2010 National Public Radio — On Wednesday, Apple overtook Microsoft as the world's most valuable technology company, at least by one Wall Street measure -- market capitalization. Michele Norris talks with Kyle Conroy, a computer science student at the University of California, Berkeley about a table he's compiled that looks at how much money you might have today had you invested in Apple stock instead of buying Apple products, such as iMacs and iPods.

U.S. Congress hears benefits of synthetic biology

05/27/10 Reuters — Synthetic biology can be used to make nonpolluting fuel, instant vaccines against new diseases and inexpensive medicines, but it will take time, collaboration and a nurturing regulatory environment, scientists said on Thursday. Jay Keasling of the University of California Berkeley Synthetic Biology Engineering Research Center said his team's work had already been used as the foundation for two biofuel companies, and that vaccine maker Sanofi Aventis has licensed technology to make engineered brewer's yeast that produces the anti-malarial drug artemisinin. He expects production to provide the drug at cost to the developing world within two years.

Berkeley quake trial shows bridge safety ideas

05/27/10 San Francisco Chronicle — A mock-up bridge and a mock-up rail car shook, rattled, but never rolled as earthquake engineers from UC Berkeley demonstrated a system designed to keep bridge traffic moving even in the strongest of seismic shaking. The 30-foot, scale-model bridge, designed and built by researchers at the university's Pacific Earthquake Engineering Research Center, was erected on a huge "shake table" that created the same violent ground motions that have marked major quakes in California, Japan and Chile.
