Researchers at the University of Chicago taught AI to write realistic restaurant reviews using Yelp reviews as an example. The reviews aren't written perfectly, but it's tough to spot the difference between real and AI-generated reviews.

Why it matters: People take reviews seriously — the researchers cited studies that found a one-star increase on Yelp can boost restaurant revenue by 5 to 9%. AI-generated reviews, if negative or revealed to be fake, could be a blow to review-oriented websites like Yelp and Amazon, and the products and services that rely on them.

What to watch for: Perfection may not be that far off: researchers can use advanced software to create better neural networks, making results even more believable. This would make it easier for AI to mass produce fake reviews or maybe even fake news.

Biden confronts mounting humanitarian crisis at the border

Just over a month into his presidency, President Biden is staring down a mounting crisis at the border that could be just as bad as the ones faced by Barack Obama and Donald Trump, if not worse.

Why it matters: Immigration is an issue that can consume a presidency. It's intensely and poisonously partisan. It's complicated. And the lives and welfare of vulnerable children hang in the balance.

The rise of vaccine passports

Vaccine passports were touted early in the pandemic as an important piece of the plan to get people back to normal life. Now they’re becoming a reality.

Driving the news: CLEAR, the secure digital identity app that you see in airports around the world, and CommonPass, a health app that lets users securely access vaccination records and COVID test results, have joined forces.

"Vaccine tourism" stretches states' supplies

Americans who are highly motivated to get vaccinated are traveling across state lines after hearing about larger vaccine supplies or loopholes in sign-up systems.

Why it matters: "Vaccine tourism" raises ethical and legal questions, and could worsen the racial socioeconomic and racial inequalities of the pandemic.
