Sensors Could Give Elderly an Assist

10/02/08 — Most people hope to live healthy, independent lives through their elderly years. But that's not always the case because, as people age, they and their loved ones have to worry about not only illnesses, but also injuries, especially from falls. For seniors, falling is the leading cause of injury deaths, nonfatal injuries and hospital admissions. But one team of researchers is working to enable the elderly to live independently through a network of body sensors. The project could allow computers to remotely monitor and analyze the activity of seniors so that, if they fall or stop moving, help can arrive quickly.

Nano Camp is a Macro Hit

09/02/08 — For the average teen, “What I Did on My Summer Vacation” doesn't normally involve building a faster supercomputer, perfecting a lab on a chip or designing a device called an optical antenna that sniffs out bomb residue. Thanks to an innovative UC Berkeley summer program, 15 high school students conducted hands-on research on these and other high-flying topics--all linked to groundbreaking nanoscale science and technology work taking place on campus. The Summer High-School Apprenticeship Research Program turns teens into bona fide scientific investigators.

Securing Our Cyberspace

09/02/08 — Information technology is pervasive in making our lives so much easier, that is, until we're paralyzed by a virus invading our home computer or crippled by an enterprise-wide system crash. The larger implications are something we don't even want to think about: What would happen to your life as you know it if your personal identity were stolen or, worse, some malicious entity hacked into just one component of our critical infrastructure, like the power grid or the air traffic–control infrastructure?

Radical Transparency

06/02/08 — Someday, you might read the morning's news headlines on the back of your cereal box. That's the latest possibility demonstrated by the EECS Organic Electronics Group. They have recently been experimenting with zinc oxide, a familiar ingredient in sunblock and diaper cream that has the special properties of working as a semiconductor while also being 93 percent transparent. The researchers already have a palette of inks that can deposit conducting, semiconducting and insulating materials-the building blocks of all solid-state electronics-on a variety of surfaces.

Genealogical Conclusions

05/02/08 — There are about six billion base pairs in the human genome, and our family tree includes about six billion living humans. So, although DNA sequencing begins in a laboratory, it requires research-level computer science and statistics to crunch the resulting mass of data and make sense of the results. As EECS and statistics professor Yun Song remarks, “Just 15 years ago, it was very difficult for population genetics researchers to run their computationally intensive analyses on desktop computers. It's thanks to relatively recent improvements in computers and algorithms that these problems have become tractable.”

Down to the Wire

04/02/08 — For years, nanoengineers have known how to create tiny wire transistors, sensors, light emitters and other useful components, but there's been no sure way to assemble them into integrated circuits because they're too small to manipulate. “You could look at things under a microscope, but you couldn't touch them,” explains EECS professor Ming Wu. But Wu and his research group have developed “optoelectronic tweezers” that can individually address wires and other nanoscale objects and convey them to precise locations. This has been the field's most challenging problem, and solving it paves the way for an entire class of devices from microdisplays to medical imaging tools.

A Search Giant

04/02/08 — It's no surprise that a Google search for Peter Norvig turns up tens of thousands of hits. Norvig (Ph.D. '86 EECS) literally wrote the book on artificial intelligence, coauthoring a bestselling textbook on the subject with Professor Stuart Russell in 1995. As the senior computer scientist at NASA Ames Research Center, he led the team that developed the remote artificial intelligence software that flew aboard the Deep Space 1 spacecraft in 1999. And today, as Google's director of research, Norvig is transforming the way information is organized and accessed on the Web.

Play It Again, IRENE

01/02/08 — EECS undergraduate Henry Wang had never heard of Enrico Caruso until last year. That's a surprising admission given that the 21-year-old senior now spends hours weekly scrutinizing the famed tenor's rendition of La Donna è Mobile. Wang is part of an ambitious project that seeks to preserve historic collections of music, speeches and other audio recordings dating back to the earliest days of recorded sound.

Steve Beck (B.S. ’71 EECS): Giving Back and Getting a Lot in Return

12/02/07 — Steve Beck, 57, has harnessed his passion for video with a vengeance. A noted artist specializing in the use of electronic video, Beck is also the developer of more than 500 commercial electronic products ranging from an energy management system to electronic toys and video games. Beck, whose electronic art is in the collections of such prominent institutions as The Museum of Modern Art, New York, was named EECS Alumnus of the Year in 2003.
