The coronavirus SARS-CoV-2 has upended life as we know it in a matter of months. But at the same time, an unprecedented global effort to understand and contain the virus—and find a treatment for the disease it causes—is underway. Join doctors on the front lines of the fight against COVID-19 as they strategize to stop the spread, and meet the researchers racing to develop treatments and vaccines.

Scientists race to understand and defeat the coronavirus behind the COVID-19 pandemic.

Our producer gets her own blood tested and investigates what exactly these “magic” molecules are, why public health professionals are eager to roll out antibody testing, and just what antibody tests can—and can’t—tell us.

Can an antibody blood test tell if you are immune to COVID-19?

Why Antibody Tests Don’t Yet Reveal Coronavirus Immunity

Scientists are trying new, revolutionary techniques to make a SARS-CoV-2 vaccine, but face challenges along the way.

The coronavirus has unleashed global havoc. Learn how scientists are hitting back.

Can Scientists Use RNA to Create a Coronavirus Vaccine?

Here’s what you need to know about the SARS-CoV-2 virus and the disease it causes, called COVID-19. 

UPDATE: Preliminary studies suggest the coronavirus spreads from people with no symptoms. A March 17 study shows the virus can remain viable in aerosols for 3 hours, on cardboard for up to 24 hours, and on plastic and stainless steel for 2 to 3 days.

What is covid-19 and should you be worried?

What We Know and Don’t Know about the Coronavirus

There are more viruses than stars in the universe, and luckily, most are harmless to us. But danger can come when we're exposed to a virus we’ve never encountered before.

The virus likely is not a new entity on Earth, but it is new in humans.

NOVA investigates the story of cannabis from the criminalization that has disproportionately harmed communities of color to the latest medical understanding of the plant. What risks does cannabis pose to the developing brain? How much do we know about its potential medical benefits? As cannabis becomes socially accepted, scientists are exploring its long-term health consequences. (Premiered September 29, 2021)Check out a previously recorded panel discussion and audience Q&amp;A featuring experts and producers from "The Cannabis Question" <a href="https://youtu.be/nSTT5RZ_hxA">here</a>.

As state-legalized cannabis spreads, NOVA explores its little-known risks and benefits.
