If your genes make you a "night owl," the odds are higher you'll develop depression. Can we do anything to change that? Also, why is the EU planning to store our vaccination information inside a QR code, of all places? And, finally, a big shout-out to the listener who won our bird quiz!

Know someone who does puzzles to "keep their brain sharp"? We've got bad news for them. Also, it's time to forget herd immunity and embrace the idea of booster shots.

In a month or so, EU citizens are supposed to get a "digital COVID-19 vaccine passport" which they will be able to use to travel. But what will it actually look like? Where will this (private) health data be stored? Who has access to it? And could it be hacked?

Seven birdcalls. That was the challenge we put to you just over a week ago. And now, it's time for a reckoning.

What is "black fungus," and how is it related to COVID-19? What are the arguments for — or against — vaccinating pregnant women? And why do people think they're more attractive right before a bar closes?

More than 100,000 pregnant women have been vaccinated against COVID-19. What does the data show?

Have an ear for birdsong? Neither do we. But with a couple clues (and a digital tool), we think you can solve our bird quiz. Also, some new fertility data shows some pretty wild differences between countries, and three big updates on major COVID-19 vaccines.

Some surprisingly positive news about China's CoronaVac, a formal complaint against Russia's Sputnik V, and Germany bucks the baby trend.

Chirp, chirp. It's time to relax. So kick off your shoes, put your feet up, lean back and just enjoy the birdsong. And if you recognize a few of the calls in our quiz, please take a second and send your answers to [email protected].

The more people who vaccinate, the quicker life goes back to normal. But is there a (proven) way to convince the "on the fence" crowd to go get jabbed? Also, once life does get back to normal, how do I get back to normal — and maybe even start growing again?
