A comparison of normal and germ-free mice revealed that as much as 70 percent of a mouse’s gut chemistry is determined by its gut microbiome. Even in distant organs, such as the uterus or the brain, approximately 20 percent of molecules were different in the mice with gut microbes.
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.
A new study at UC San Diego, published February 11, 2020, found that exposure to heatwaves during the last week of pregnancy was strongly linked to an increased risk of preterm delivery – the hotter the temperature or the longer the heatwave, the greater the risk.
Researchers from the University of California San Diego, University of Texas at Austin, Stanford University and Mozilla have developed a new framework to improve web browser security. The framework, called RLBox, has been integrated into Firefox to complement its other security-hardening efforts.
UC San Diego researchers suggest that prolonged exposure to a pair of antioxidant proteins may contribute to enlargement of the liver and fatty liver diseases.
UC San Diego announced a gift from Nissi and Ajit Varki, both professors at the university. The gift has been designated for the Center for Academic Research and Training in Anthropogeny (CARTA) to support a broad range of activities, including scholarly studies of the origins of humankind.
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.
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.
