Researcher Grace O’Connell, an assistant professor of mechanical engineering at UC Berkeley, is advancing ways to grow human disc tissue — the spongy, protective material between vertebrae — and other engineered cartilage surfaces in a lab.
Humans can’t survive more than a few days without water, but some plants, in particular mosses, can survive drought for decades and suddenly revive with the first rain. KQED’s “Deep Look” team visited UC Berkeley’s University and Jepson Herbaria to learn about these so-called “resurrection plants.”
Philomathia Innovation Seed Fund recipients Catherine Wolfram and Meredith Fowlie carried out a rigorous study that found surprisingly low savings relative to costs in part of a nationwide effort to improve home energy-efficiency.
Chen Li, a Miller Postdoctoral Fellow, studied the maneuvering ability of cockroaches with rounded shells and saw that their simple streamlined shape allowed them to easily roll and slip through gaps in a clutter of objects, such as grass and leaves on a forest floor.
The debate over the legalization of marijuana has focused primarily on questions of law, policy and health. But a new paper co-authored by UC Berkeley researchers shines a spotlight on the environmental damage caused by illegal marijuana plantations in sensitive watersheds.
Like homing pigeons, humans have a nose for navigation because our brains are wired to convert smells into spatial information, new research shows. Similar investigations have been conducted on birds and rodents, but this is the first time smell-based navigation has been field-tested on humans. The results evoke a GPS-like superpower one could call an “olfactory positioning system.”
UC Berkeley researchers have developed an easy way to put bacteria under a molecular lock and key in order to contain its accidental spread. The method involves a series of genetic mutations that render the microbe inactive unless the right molecule is added to enable its viability.
Jill Banfield, professor of EPS and ESPM, and grad student Christopher Brown discovered a large number of new groups or phyla of bacteria, suggesting that the branches on the tree of life need some rearranging. The more than 35 new phyla equal in number all the plant and animal phyla combined.
Sharp images obtained by the Hubble Space Telescope confirm that three supernovae discovered several years ago exploded in the dark emptiness of intergalactic space, having been flung from their home galaxies millions or billions of years earlier.
