How an undercover content moderator polices the metaverse
When Ravi Yekkanti puts on his headset to go to work, he never knows what the day spent in virtual reality will bring. Who might he meet? Will a child’s voice accost him with a racist remark? Will a cartoon try to grab his genitals?
Yekkanti’s job, as he sees it, is to make sure everyone in the metaverse is safe and having a good time, and he takes pride in it. He’s at the forefront of a new field, VR and metaverse content moderation.
Digital safety in the metaverse has been off to a somewhat rocky start, with reports of sexual assaults, bullying, and child grooming—an issue that’s only becoming more urgent with Meta’s recent announcement that it is lowering the age minimum for its Horizon Worlds platform from 18 to 13.
Because traditional moderation tools, such as AI-enabled filters on certain words, don’t translate well to real-time immersive environments, mods like Yekkanti are the primary way to ensure safety in the digital world. And that work is getting more important every day. Read the full story.

The flawed logic of rushing out extreme climate solutions
Early last year, entrepreneur Luke Iseman says, he released a pair of sulfur dioxide–filled weather balloons from Mexico’s Baja California peninsula, in the hope that they’d burst miles above Earth.
It was a trivial act in itself, effectively a tiny, DIY act of solar geoengineering, the controversial proposal that the world could counteract climate change by releasing particles that reflect more sunlight back into space.
Entrepreneurs like Iseman invoke the stark dangers of climate change to explain why they do what they do—even if they don’t know how effective their interventions are.. But experts say that urgency doesn’t create a social license to ignore the underlying dangers or leapfrog the scientific process. Read the full story.

A chatbot that asks questions could help you spot when it makes no sense
The news: AI chatbots often present falsehoods as facts and have inconsistent logic, and that can be hard to spot. One way around this problem, a new study suggests, is to change the way the AI presents information.
Why it matters: Getting users to engage more actively with the chatbot’s statements might help them think more critically about that content. The researchers hope their method could help develop people’s critical thinking skills as they use AI chatbots in school or when searching for information online. Read the full story.

How bugs and chemicals in your poo could give away exactly what you’ve eaten
Our waste contains the stuff that our bodies are generally trying to get rid of. But it can also provide insight into our gut microbiomes and how they influence our health.
Scientists are getting better at collecting and making sense of the bugs and chemicals that end up in our stool, including guessing the kinds of food we’ve eaten with surprising accuracy. Not only could this help improve research into how our bodies process food, but also to better our overall health. Read the full story.

The big story
How to befriend a crow
The crows play hide-and-seek with Nicole Steinke after her older kids head to school. She feeds a family of the birds from her apartment balcony in Alexandria, Virginia, twice daily. Once there’s no food left, they’ll look for her as she walks around her neighborhood. When one crow finds her, it will call to the others, and they’ll surround her.
The crows have become minor TikTok celebrities thanks to CrowTok, a small but extremely active niche on the social video app that has exploded in popularity over the past two years. CrowTok isn’t just about birds, though. It also often explores the relationships that corvids—a family of birds including crows, magpies, and ravens—develop with human beings.
They’re not the only intelligent birds around, but in general, corvids are smart in a way that resonates deeply with humans. But how easy is it to befriend them? And what can it teach us about attention, and patience, in a world that often seems to have little of either? Read the full story.
