Antibodies that recognize and block SARS-CoV-2 infection have the potential to be powerful weapons. An infectious disease expert explains what antibodies are and how they could be used as a therapy.
The world takes tentative steps to get back up and running amid the COVID-19 pandemic, but our post-pandemic world will look different than how we lived and worked before.
Our experts look at recovery efforts, how different the post-pandemic world will be, the hunt for a cure for COVID-19, and why we need to mind our mental health.
