Nanoengineers at the University of California San Diego have developed COVID-19 vaccine candidates that can take the heat. Their key ingredients? Viruses from plants or bacteria.
Since the early days of the pandemic, wastewater has played a vital role in the fight against SARS-CoV-2. While the virus primarily attacks the respiratory system, it replicates in the gastrointestinal tract, travels into stool, and eventually reaches sewage systems. This knowledge allowed researchers to devise a wastewater surveillance system that detects presymptomatic and asymptomatic…
Conventional wisdom on viral disease transmission needs updating, international science team concludes
Supercomputing-derived movies reveal details of deceptive sugar coating on spike protein, presenting new possibilities to block cell entry and infection
Part of the university’s Return to Learn program, wastewater screening helped prevent outbreaks by detecting 85 percent of cases early, allowing for timely testing, contact tracing and isolation
The coronavirus that causes COVID-19 also tends to co-locate with one particular type of bacteria
The blood sugar-lowering drug metformin prevented pulmonary inflammation, a major factor in COVID-19 severity and mortality, in studies of mice infected by the SARS-CoV-2 coronavirus
Researchers at University of California San Diego School of Medicine have discovered one way in which SARS-CoV-2, the coronavirus that causes COVID-19, hijacks human cell machinery to blunt the immune response, allowing it to establish infection, replicate and cause disease.
As the COVID-19 pandemic proliferated in early 2020, tracking the spread of a frequently asymptomatic virus presented a novel challenge for public health officials. Diagnostic testing was often unavailable and not fast enough to act as a useful forecasting tool. While symptoms can take several days to appear, the virus immediately begins replicating in the…
Automated process helps test city sewage for SARS-CoV-2, allowing researchers to forecast the region’s caseload one to two weeks ahead of clinical diagnostic reports
