The lab-leak hypothesis for COVID-19 is becoming a conspiracy theory

To explain where SARS-CoV-2 came from, look at processes with scientific explanations and precedents

The Moderna mRNA vaccine works against newly emerged COVID-19 mutants

Mutants like B.1.1.7 and B.1.351 carrying changes in the virus spike protein appear to help the virus spread, but not to evade currently available vaccines

How the COVID-19 vaccine is distributed determines how the pandemic will end

National health care systems will make things more organized, but the US is still finding its footing

Monkeys and apes in Africa and Asia are also susceptible to SARS-CoV-2

New research compared the configurations of the ACE2 protein in 29 non-human primates

How does Pfizer’s "90% effective" COVID-19 vaccine work?

Pfizer made a big news splash, but is their mRNA vaccine a silver bullet?

Testing for lesser known antibodies produces a better COVID-19 test

Most antibody tests look for responses to SARS-CoV-2's spike protein, but more accurate results include antibodies against the virus's other proteins

Traditional Chinese medicine could help treat COVID-19

Chinese doctors took this approach with SARS in 2003, and are hoping it could work again

Antibody testing is increasing, but what do the results mean?

The answer to whether people previously infected with COVID-19 are immune remains unclear

Drug repurposing gave remdesivir its second, third, and fourth chance

The antiviral has had a charmed life, failing multiple times but coming back again and again

To understand SARS-CoV-2, scientists found its wild cousins

The original host of this virus is still in question, but studying similar viruses can help us figure out how it evolved

T cells could be the key in developing an effective COVID-19 vaccine

Our bodies have two main types of T cells. Together they can help us fend off this virus

No one really knows if coronavirus is going away in the summer

Which is all the more reason to continue strengthening policy and public health responses
