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.
Antibodies are incredibly good at finding the coronavirus. Antigen tests put them to work.

An antigen test was given emergency use authorization by the FDA in early May. A biochemist explains how COVID-19 antigen tests work.
Here's what we know about immunity to COVID-19, and what that means for getting life back to normal.
A potential vaccine for coronavirus is undergoing a human trial in Australia. It's based on a vaccine that was already in development for influenza, and has shown promise in animal studies.
It’s not yet clear whether antibodies in the blood of patients who have been infected with SARS-CoV-2 indicate immunity. Above: blood specimens for COVID-19 antibody tests.

Immunity to COVID-19 may be complicated. Here are the promises and pitfalls of antibody tests.
The coronavirus is really just an inanimate packet of genetic material.

Thinking of SARS-CoV-2 as an invisible enemy with an evil personality and humanlike motivations is a natural offshoot of the way people evolved to anthropomorphize so as not to overlook threats.
You're heading to your first post-COVID-19 dinner party. How many guests is too many? Are hugging and handshakes OK now? And most importantly, should you bring your own cutlery?

One of the methods researchers are exploring to combat COVID-19 is gene editing: altering the genome of the virus to make it harmless.
Gustav Klimt’s ‘Death and Life’ suggests the way many people are unaware of death’s ever-present influence.
It's human nature to try to insulate yourself from the unpleasant realization that death comes for all of us eventually.
Moderna just released the results of a phase 1 trial for a COVID-19 vaccine.

Results from phase 1 trials of a COVID-19 mRNA vaccine created a burst of optimism. But details the company failed to release suggest it is too early to speculate whether the vaccine is effective.

The US president has reignited controversy over the use of malaria drugs to guard against COVID-19. But there is little reliable evidence so far that this tactic is safe or effective.
Bats are key pollinators and seed-spreaders, and keep pests away.
Bats get a lot of negative press, but they also make positive contributions to the environment and to our lives.
Immune cells release proteins called cytokines which alert the rest of the immune system that a virus is present.
We blame the coronavirus for the thousands of deaths, but it is actually a hyperactive immune reaction that is the cause of death. An immunologist explains.
What if you could test yourself for coronavirus with a test in the comfort of your home?

Testing for coronavirus has been a fiasco in the US. But now companies are developing super fast tests, including ones that might eventually be as simple as at home pregnancy tests.
The SARS-CoV-2 coronavirus is currently detected using invasive nasal swabs. But the virus is also present in saliva, potentially paving the way for cheaper, safer tests that people could do at home.
The US and its allies are demanding answers over how COVID-19 became a pandemic. But instead of pointing fingers at China, the inquiry should focus on scientific clues to help us thwart future disasters.
No matter the details of the plot, conspiracy theories follow common patterns of thought.

Conspiracy theories about COVID-19, such as those advanced in the video 'Plandemic,' tend to pull from the same playbook. Recognizing that can help keep you from falling for this kind of thinking.

The ACE2 receptor allows the virus that causes COVID-19 to infect and destroy our cells. What is the normal role of ACE2 in the body, and could it be the key to blocking infection?
AI can help doctors tackle new problems.

Researchers from New York University are designing AI algorithms to help predict COVID-19 outcomes.
Evidence is growing that when masks are worn by nearly everyone, it can slow coronavirus transmission.

Recommendations around mask usage are confusing. The science isn't. Evidence shows that masks are extremely effective to slow the coronavirus and may be the best tool available right now to fight it.
