Macrophage subgroups may play pivotal role in COVID-19 lethality

Many researchers are attempting to identify risk factors for severe or critical COVID-19. A recent paper in the journal Medical Hypotheses in September 2020 suggests that macrophage class activation is one of the factors that determine the clinical phenotype of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Rapid detection of SARS-CoV-2 with portable CRISPR-based mobile phone diagnostic test

A large group of researchers from the United States reported developing an amplification-free CRISPR-based mobile phone assay for direct detection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from nasal swabs. Their state-of-the-art paper is currently available on the medRxiv* preprint server.
