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.

Decoding COVID-19

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.

How Viruses Like the Novel Coronavirus Evolve

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?

What goes on inside those test tubes to detect whether a person is positive for SARS-CoV-2, the virus that causes COVID-19?

How Coronavirus Tests Work

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

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?

Follow along as NASA launches the Mars 2020 Mission, perhaps the most ambitious hunt yet for signs of ancient life on Mars. In February 2021, the spacecraft blazes into the Martian atmosphere at some 12,000 miles per hour and lowers the Perseverance Rover into the rocky Jezero Crater, home to a dried-up river delta scientists think could have harbored life. Perseverance will comb the area for signs of life and collect samples for possible return to Earth. Traveling onboard is a four-pound helicopter that will conduct a series of test flights—the first on another planet. During its journey, Perseverance will also test technology designed to produce oxygen from the Martian atmosphere, in hopes that the gas could be used for fuel—or for humans to breathe—on future missions.
