UCR Engineers Developing Tiny Devices That Can "Hear" Cancer
Nov 10, UCR -- Two engineering professors at UC Riverside are developing devices 100,000 times thinner than a human hair, that can listen to cancerous cells, deliver chemotherapy to them and leave surrounding healthy tissue intact.

Abalones may owe their huge size to otters
Nov 09, UCB -- California sea otters are maligned for their ruthless pursuit of large abalones prized by divers. But a new study suggests that otters are partly responsible for the size of these abalones, some a foot across.

Discovery of Molecular Signature Will Aid in Treatment of Brain Tumors
Nov 09, UCLA -- Researchers have identified key characteristics in certain deadly brain tumors that make them 51 times more likely to respond to a specific class of drugs.

New system for earthquake early warning
Nov 09, UCB -- UC Berkeley seismologist Richard Allen has found that the frequency of P waves produced within the first four seconds of an earthquake provides enough information to estimate the ultimate magnitude of the earthquake. Using a system called ElarmS, he and colleagues are able to predict distant ground motion and send warnings to areas of potentially damaging shaking, providing seconds to tens of seconds of advance warning.

UCSF surgeon develops new spinal surgery technique
Nov 04, UCSF -- UCSF surgeons are using a novel technique to remove tumors from the cervical region of the spine that were previously thought "inoperable."

New X-rays of cell's ribosome could lead to better antibiotics
Nov 03, UCB -- The ribosome, a nano-machine that manufactures all of our cells' proteins, is also a target of many antibiotics. New, sharp X-ray images of the ribosome will help researchers understand how today's antibiotics interfere with the machine, and could lead to improved drugs that throw a wrench into it.

California chicken owners should be on lookout for avian flu
Nov 03, UCOP -- This fall and winter, as migratory birds make their way down the Pacific Flyway, they may be packing avian flu, including the deadly and much-publicized H5N1 variant.

Cleaning the Salton Sea
Nov 03, UCR -- UC Riverside scientists are able to improve water quality by 90 percent in the rivers flowing into the Salton Sea, the largest lake in California.
