COVID-19 vaccination rates are going up. Spring birds (at least here in the northern hemisphere) are chirping an end to the winter of Corona. But research says we might need help recalling how to feel happiness and live fulfilling lives. Here are a few thoughts on how to start flourishing.

Will countries actually reach herd immunity? It's an open question. But studies have shown that there are a few "tricks" to get people to immunize — even if they've already decided not to.

"A life for a life, an eye for an eye." There's a tendency to downplay, or even willfully ignore, some of the most blatant, barbaric language that's tucked inside the holy books of Christians, Muslims and Jews. But a novel experiment shows that these outdated verses, when quoted to believers, cause real-world harm today.

From a risk/reward standpoint, does it make sense to fly to another country to get vaccinated there? Also, is it OK to breastfeed if you have COVID-19 but don't know it yet? Or if you just got vaccinated? Finally, human happiness takes a hit, and Twitter users hit the bottle a bit too hard.

The later it gets at a bar or pub, the more likely it is you'll meet someone who thinks they're pretty hot stuff. Oddly, though, a new study suggests this "closing time" effect has nothing to do with alcohol. So what is going on?

One more beer? Or an extra glass of wine? Sure. It's a pandemic. But drinking to the point of blackout — entirely ON YOUR OWN — really is a problem. And if previous pandemics are any clue, what happens during lockdown doesn't stay there.

Researchers in Germany have disproven the idea that happiness is 'u-shaped' — saying the data clearly shows we're more likely to become unhappier over time. So... what on earth are we supposed to do with that information?

If you’ve happened to hear about an asthma medication that will ameliorate or perhaps prevent COVID-19, think twice before you go looking for an inhaler. And, of all the things that have changed in the past year, is your personal hygiene one of them?

Want to visit the EU this summer? There's a good chance you'll be able to (if you've got the right vaccine and passport). Also, some fantastic news in the fight against a disease that infects 200 million people a year, and a look at the raw research on curfews.

It was called a "breakthrough" — a study showing that a common asthma medication could be used to improve people's chances of surviving COVID-19. Now, doctors in Germany and Austria are not only casting doubts on the study itself, but are extremely concerned about its consequences.
