Many futurists envision a world in which polymer membranes with molecular-sized channels are used to capture carbon, produce solar-based fuels, or desalinate seawater, among many other functions. This will require methods by which such membranes can be readily fabricated in bulk quantities. A technique representing a significant first step down that road has now been successfully demonstrated. Berkeley Lab and UC Berkeley researchers — led by materials scientist Ting Xu — have developed a solution-based method for inducing the self-assembly of flexible polymer membranes with highly aligned subnanometer channels.

Four UC Berkeley faculty named AAAS fellows

Four UC Berkeley faculty members have been named 2010 Fellows of the American Association for the Advancement of Science (AAAS), the world's largest general scientific society and publisher of the journal Science.

Wildlife biologists put dogs' scat-sniffing talents to good use

UC Berkeley biologists have harnessed dogs' natural talent for sniffing out the scat of other animals for a good cause. With the help of Working Dogs for Conservation, a Montana-based nonprofit organization, researchers are fine-tuning the use of dogs as a non-invasive tool for wildlife studies and management.

Possible missing link between young and old galaxies

UC Berkeley astronomers may have found the missing link between young, gas-filled, star-forming galaxies and older, gas-depleted galaxies typically characterized as “red and dead.” Leo Blitz and Katherine Alatalo report that a long-known “early-type” galaxy, NGC 1266, is expelling molecular gas, mostly hydrogen, from its core. The unusual galaxy may help explain how gas-filled galaxies rid themselves of their molecular gas.

Advance makes MRI scans more than seven times faster

UC Berkeley physicist David Feinberg, in collaboration with physicians at the University of Minnesota, has combined two new techniques to speed MRI scans of the brain by more than a factor of 10. The faster functional MRI scans will boost the national effort to map the brain’s wiring, called the Human Connectome Project.
