Newly Discovered Bat Viruses Give Hints to Covid’s Origins

Coronaviruses discovered in Laotian bats are surprisingly adept at infecting human cells, showing that such deadly features can indeed evolve outside of a lab.

Scientists Press Case Against the Covid Lab Leak Theory

In a review of recent studies and comparisons to other outbreaks, a group of virologists contends that there is more evidence to support a natural spillover from animals to humans.

The Warnings About the Coronavirus That Were Ignored

Even if the coronavirus did not emerge from a lab, the groundwork for a potential disaster had been laid for years, and learning its lessons is essential to preventing others.
