Magnetic nanodiscs can be activated by an external magnetic field, providing a research tool for studying neural responses.

A replicating RNA vaccine, formulated with a lipid-based nanoparticle emulsion, produces antibodies against the COVID-19 coronavirus in mice and primates with a single immunization. These antibodies potently neutralize the virus in young and old animals. The antibody levels induced are comparable to those in recovered COVID-19 patients. This formulation is shelf-stable, with mass-production and distribution advantages.

A phase 2 randomized controlled trial of a recombinant adenovirus type-5-vectored COVID-19 vaccine (Ad5-vectored COVID-19 vaccine) was conducted in China in April 2020 and involved more than 500 people. The primary objective of the study was to evaluate the immune response and safety of the vaccine, and to determine the most suitable dose for a phase 3 trial. Phase 3 trials are needed to confirm whether the vaccine candidate effectively protects against SARS-CoV-2 infection.

A new blood test that reliably predicts outcomes for heart failure patients could lead to new diagnostics and treatments for COVID-19 patients as well, according to new research.
