Food delivery by drone is just part of daily life in Shenzhen

—Zeyi Yang

In a buzzy urban area in Shenzhen, China, I watched as a drone descended onto a pickup kiosk to deliver the iced tea I’d ordered half an hour earlier. The delivery service is operated by Meituan, China’s most popular food delivery platform, which has been making regular drone deliveries to the city’s residents for the past year and a half.

What differentiates Meituan from its American peers is that it’s flying drones in potentially the most challenging environment: dense urban neighborhoods. For some Shenzhen residents and vendors, delivery by drone is no longer a novelty—it’s part of their daily routine. And the company’s progress shows that regular drone delivery in cities is possible.

Our quick guide to the 6 ways we can regulate AI

AI regulation is hot. Ever since the success of OpenAI’s chatbot ChatGPT, the public’s attention has been grabbed by wonder and worry about what these powerful AI tools can do.

Tech CEOs, US senators and leaders at the G7 summit are all united in their desire for international standards and stronger guardrails to govern AI. Melissa Heikkilä, our senior AI reporter, has analyzed six different international attempts to regulate the technology, and given each of them a score for how influential they are. Take a look at what she came up with.

This story is part of our Tech Review Explains series, dedicated to untangling the complex, sometimes messy, world of science and technology to help you understand what's going on. Check out the other stories in the series.

Brain waves can tell us how much pain someone is in

The news: Brain signals can be used to detect how much pain a person is experiencing, which could overhaul how we treat certain chronic pain conditions, a new study has suggested. Electrodes implanted in the brains of four people living with chronic pain helped researchers to track their individual levels of pain, and to train an AI model to accurately predict its severity.

Why it’s important: Because we still don’t really understand how chronic pain affects the brain, it’s very difficult to treat. This research is the first time a human’s chronic-pain-related brain signals have been recorded, and it could aid the development of personalized therapies for the most severe forms of pain.

Meta’s new AI models can recognize and produce speech for more than 1,000 languages

What’s happened: Meta has built AI models that can recognize and produce speech for more than 1,000 languages—a tenfold increase on what’s currently available. It’s making them open source to help developers working in different languages to build new speech applications—like messaging services that understand everyone, or virtual-reality systems that can be used in any language.

Why it matters: Meta says the new project is a significant step toward preserving languages that are at risk of disappearing. Although there are around 7,000 languages in the world, existing speech recognition models cover only about 100 of them. Read the full story.

The big story 

Uyghurs outside China are traumatized. Now they’re starting to talk about it

 

June 2021

The Uyghur diaspora have been forced to watch from afar as their loved ones disappear and a way of life is erased. The trauma has sparked a mental health crisis that leaders in the diaspora say is all too apparent.

Many are reluctant to seek help, leaving the community’s needs both underassessed and unmet. But a small group of outspoken Uyghurs is trying to change that. Using social media, they’re starting conversations about grief and mental health and, through telehealth, connecting people across the country with volunteer therapists. Read the full story.
