A patient-reported symptom tracking method used for patients with cancer has now been adapted for patients with COVID-19. The first clinical case series showed that famotidine may help COVID-19 patients with mild to moderately severe symptoms.

Human genetic diversity wouldn't be possible without DNA crossovers in egg and sperm cells. Two studies provide new insights into how crossovers go right -- and wrong, leading to infertility, miscarriages and birth defects.

Researchers have shown that a newly discovered natural antibiotic, teixobactin, could be effective in treating bacterial lung conditions such as tuberculosis and those commonly associated with COVID-19.

Scientists can monitor biomolecular processes in live tissue by noninvasive optical methods, such as fluorescence imaging. However, the fluorescent dyes used for that purpose are often rather unstable, and photobleaching, lack of specificity, and poor pharmacokinetics are recurrent issues. Scientists have now developed a molecular shield that stabilizes near-infrared fluorescent dyes and enhances their functionality.

Scientists at Berkeley Lab's Molecular Foundry have joined forces with a research team at Stanford to aim a gene-targeting, antiviral agent called PAC-MAN against COVID-19.
