Berkeley Researchers Apply NMR/MRI to Microfluidic Chromatography

By pairing an R&D 100 award-winning remote-detection version of NMR/MRI technology with a unique version of chromatography specifically designed for microfluidic chips, Berkeley Lab researchers have opened the door to a portable system for highly sensitive multi-dimensional chemical analysis that would be impractical if not impossible with conventional technologies.

Gray whales likely survived the Ice Ages by changing their diets

If ancient gray whale populations migrated and fed the same as today’s whales, what happened during the Ice Ages, when their major feeding grounds disappeared? UC Berkeley and Smithsonian paleontologists argue that gray whales utilized a range of food sources in the past, including herring and krill, in addition to the benthic organisms they consume today. As a result, prewhaling populations were two to four times greater than today’s population of around 22,000.

Breaking Kasha’s Rule

Berkeley Lab researchers created tetrapod molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as “Kasha’s rule.” The discovery holds promise for multi-color light emission technologies, including LEDs.

Magnetic memory and logic could achieve ultimate energy efficiency

Information theory dictates that a logical operation in a computer must consume a minimum amount of energy. Today’s computers consume a million times more energy per operation than this limit, but magnetic computers with no moving electrons could theoretically operate at the minimum energy, called the Landauer limit, according to UC Berkeley electrical engineers.

Laundry duty getting you down? Robots to the rescue!

Folding laundry may seem mundane, but for a robot, identifying a 3-D object and manipulating it correctly, it’s an exercise that requires intelligence that humans may take for granted. Pieter Abbeel and his team of engineers are developing increasingly efficient strategies and algorithms to help robots fold towels, forming the foundation for the next generation.

Scientists catalog genetic aberrations in ovarian cancer

UC Berkeley researchers Terry Speed, Elizabeth Purdom, John Ngai and Yoon Gi Choi have joined colleagues at Berkeley Lab and around the country in creating the first comprehensive catalog of the genetic aberrations responsible for an aggressive type of ovarian cancer that causes most ovarian cancer deaths. This “atlas” could lead to targeted treatment based on a person’s cancer fingerprint.

Patrick Kirch awarded Gregory Medal for Pacific research

Patrick V. Kirch, a UC Berkeley professor of anthropology and integrative biology and an authority on the archaeology of the Pacific Islands, has been awarded the 2011 Herbert E. Gregory Medal for Distinguished Service to Science in the Pacific Region.
