Pavel Durov, the CEO of Telegram, a popular messaging app, tweeted: "Iranian authorities are blocking access to Telegram for the majority of Iranians after our public refusal to shut down ... peacefully protesting channels."

Geopolitical tensions are foiling efforts to get to the bottom of how COVID-19 originated.

Why it matters: Insights into how COVID-19 began can help us prevent future pandemics — especially if it involved any kind of leak or accident at a virology lab.
