What to know about this autumn’s covid vaccines

Many people have started testing positive for covid recently. Hospitalizations for the disease in the US rose nearly 16% during the third week of August, and even Jill Biden tested positive this week.

Data suggest we’re at the beginning of a fall wave. It’s been a year since a covid booster was released, and while the latest wave isn’t likely to be as bad as the tsunami we experienced in 2021-2022, there’s a lot of uncertainty about what the next few months look like. 

So, where are the updated shots to help protect us? And how do they stack up against the challenging new variants? Read the full story.

How should we regulate AI?

Deciding how to regulate AI is one of the biggest challenges facing politicians and experts alike. On September 12 we’re holding the second MIT Technology Review Roundtable: a 30-minute conversation with our writers and editors—and this one’s all about governing AI.

Melissa Heikkilä, our senior reporter for AI, will be chatting with news editor Charlotte Jee about what should be done to keep AI companies in line. Roundtables are free for MIT Technology Review subscribers, so if you’re not already, you can become one today from just $80 a year.

The big story

VR is as good as psychedelics at helping people reach transcendence

August 2022

After a near-death experience, artist and physicist David Glowacki tried to recapture the hallucinatory transcendence he felt. A VR experience called Isness-D is his latest effort.

On four key indicators used in studies of psychedelics, the program showed the same effect as a medium dose of LSD or psilocybin (the main psychoactive component of “magic” mushrooms).

That means it could potentially be used to alleviate the symptoms of mental health conditions, including obsessive-compulsive disorder, addiction, post-traumatic stress disorder, and depression. Read the full story.
