OK, place your bet. Who's done better during lockdowns: introverts or extroverts? Also, what percentage of hospitalized patients still have COVID symptoms half a year later? Finally, what's the latest timeline for vaccinating children against COVID-19?

Your eating habits have probably changed during this pandemic — and in ways you might not have realized. But as three separate studies have shown, a few variables really do matter when it comes to what you'll look like (and how you'll feel) when the world opens back up.

It's a question that consumes millions of investors every single evening: Is a stock going to rise or fall tomorrow? The crazy thing is, we might actually be able to answer this question — if we could only look deep into our brains.

Do Germans have a good case for wanting things to reopen? Or it based more on psychological fatigue and social isolation? Also, does China have any science on its side when it compels (some) people to undergo an anal COVID-19 swab? And, finally, is it just anecdotal, or do Zoom and Skype conferences really have a different — and exhausting — effect on our brains than normal meetings?

You've heard the complaints, and you may have even experienced it yourself: the exhaustion that comes from too much videoconferencing. But, if traditional face-to-face meetings also make us yawn, then what is about the digital version that makes us feel even worse?

The data's clear, and so are the voices on the streets: After almost three months of strict lockdowns, Germans really seem to want their country to be more open than it is right now — even with daily infections at stubbornly high levels. But what is it they want to open, exactly? And what's the time frame?

Immigration, baggage, customs, rectal probe — according to reports from diplomats and foreigners visiting China, this is the uncomfortable sequence of events that has greeted some of them upon arrival. But what is the logic behind using anal swabs as a COVID-19 diagnostic tool? And do they have any advantages over the mouth and nose swabs we've all gotten used to?

With vaccinations lagging (and infections stagnating), what is Germany's new plan to combat the COVID-19 pandemic? Also, promising new data from the UK on the Oxford/AstraZeneca vaccine, and how Guatemala got duped into counterfeit test kits.

Are there COVID-19 vaccines that don't require a needle? How, exactly, do feelings of boredom affect the spread of the coronavirus? And if we can solve math problems and answer questions while sleeping, what does that mean for the future of learning?

If the coronavirus crisis has shown us anything, it's that human beings apparently have an irrepressible NEED to get their hair cut, styled and colored — virus be damned. But at a time when lockdowns have effectively canceled all social events, is it really about the hair?
