Two copies of the APOE4 variant, which confers a higher risk of dementia, doubles the risk of severe symptoms as a result of infection with SARS-CoV-2, according to a study.

The viral protein known as ORF3b limits the induction of the type I interferon response, which typically alerts other immune system components to the presence of a virus, in cultured cells.

Engineered Plasmodium parasites form the basis of two experimental malaria vaccines that showed safety and encouraging immune responses in clinical trials.

Affectionate touches tap into the nervous system’s rest and digest mode, reducing the release of stress hormones, bolstering the immune system, and stimulating brainwaves linked with relaxation.

A clinical trial of the shot in eight volunteers suggests that it is safe and that it generates antibodies that neutralize SARS-CoV-2, but further testing is needed, scientists say.

While the finding doesn’t prove people become immune to the virus after infection, it is good news for vaccine development.

The experiments did not involve SARS-CoV-2, but researchers say the results support precautions to avoid possibly spreading COVID-19 by talking.

The public university system in California joins a number of colleges planning a virtual semester to minimize the risk of spreading COVID-19.

Data from a crowdsourcing smartphone app is helping to track the spread of the disease in real time and reveals the symptom as the number one indicator of infection.
