Duke scientists describe inexpensive method to measure mask efficacy

Researchers at Duke University have developed a simple, low-cost method to assess the efficacy of different face masks at reducing the transmission of respiratory droplets during normal speech. Respiratory droplets are believed to be the primary way that people spread SARS-CoV-2 to one another.

Coronavirus vaccines moving forward

Development of COVID-19 vaccines is moving forward at an unprecedented pace, and the public interest and press coverage are huge. And yet it is not easy for lay person or scientist to keep track of the multitude of vaccine candidates.

Super-antibodies against SARS-CoV-2 show promising results in animals
