A long-feared scenario in which global warming causes Arctic permafrost to melt and release enough greenhouse gas to accelerate warming and cause catastrophe probably won’t happen. Researchers conclude that even if methane is released from permafrost, very little actually reaches the atmosphere.
On Feb. 6, Antarctica reached 65 degrees Fahrenheit, the same temperature San Diegans were experiencing. The day marked the warmest temperature ever recorded for the southern continent, which came just days after the Earth saw its warmest January on record.
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
In a new study, researchers at University of California San Diego School of Medicine confirmed the findings of previous pilot studies that found an association between human milk concentrations and infant weight and body composition.
More portable, fully wireless smart home setups. Lower power wearables. Batteryless smart devices. These could all be made possible thanks to a new ultra-low power WiFi radio developed by UC San Diego engineers. It enables WiFi communication at 5,000 times less power than commercial WiFi radios.
Researchers at UC San Diego School of Medicine report that abnormal levels of beta-amyloid plaques in brain predict cognitive decline and higher risk of developing Alzheimer’s disease, but also that cognitive performance predicts progression from normal to abnormal levels of beta-amyloid.
