Frustrated with spotty WiFi connection? Engineers at the University of California San Diego have developed a “smart surface” that could make signal available in dead spots—and also make the existing connection twice as fast.
UC San Diego researchers discovered that high blood levels of RNA produced by the PHGDH gene could serve as a biomarker for early detection of Alzheimer’s. The work could lead to the development of a blood test to identify individuals who will develop the disease years before they show symptoms.
UC San Diego researchers have developed a computational tool that makes modeling and simulation of complex cellular processes more true to life. The tool, dubbed GAMer 2, simplifies the process of using realistic cell geometries in mathematical models.
UC San Diego nanoengineers developed a safety feature that prevents lithium metal batteries from rapidly overheating and catching fire in case of an internal short circuit. The clever tweak does not prevent battery failure, but rather provides advance warning of failure and makes it much safer.
Engineers have created light-based technology that can detect biological substances with a molecular mass more than two orders of magnitude smaller than previously possible. The work could lead to the development of ultra-sensitive devices for quickly detecting pathogens in blood.
UC San Diego bioengineers developed a control system that could make CAR T-cell therapy safer and more powerful when treating cancer. By programming CAR T cells to switch on when exposed to blue light, the researchers controlled the cells to destroy skin tumors in mice without harming healthy tissue
Researchers led by UC San Diego built a device that sorts and separates cancer cells from the same tumor based on how “sticky” they are. They found that less sticky cells migrate and invade other tissues more than their stickier counterparts, and have genes that make tumor recurrence more likely.
Micromotors that swim to infected sites in the body to lure, trap and destroy bacteria could offer a more efficient form of treatment against pathogens. UC San Diego nanoengineers have developed a “microtrap” that zips around in acid and serves as toxic bait for E. coli bacteria.
When he was 10 years old, Oscar Vazquez-Mena learned that his ancestors, the ancient Mayans, had once been a technologically advanced culture that excelled in mathematics, astronomy, art and architecture. Yet all around him in Chiapas, his home state in Mexico, families lived in poverty and children…
