TNW Backstage returns this week to explore one of tech’s most fascinating frontiers: brain-computer interfaces (BCIs). The capabilities of these neural devices are rapidly expanding. They’ve been implanted in skulls and worn as headbands. They’ve measured focus, treated Parkinson’s disease, and enabled paralysed people to control computers with their minds. A range of research labs and tech firms are developing BCIs. Yet the spotlight has been dominated by one company: Elon Musk’s Neuralink. The startup has put brain implants in monkeys so they can play Pong with their minds. Musk also has big plans for humans, from giving us “superpowers” to downloading our memories. But shockingly, not everyone is keen on the idea of Elon controlling their brains. Thankfully, there are other options. One of them comes from Dutch healthtech company MindAffect. The company uses BCIs primarily for hearing and visual tests. Worn as headbands, the devices analyse the brain’s responses to stimulation, which reveals what the user saw or heard. It’s completely non-invasive, affordable, and requires little staff support. MindAffect’s CEO, Jennifer Goodall, discusses the system on this week’s episode of TNW Backstage. We revisit her session from TNW Conference 2024 and discuss the healthtech trends shaping this year’s event. You can listen to the show on Spotify, at our dedicated website, or via the media player at the bottom of this article. Once you’re done, check out our previous episodes of the podcast, which goes behind the scenes of TNW Conference and the tech shaping our world. In our debut show, we explored the data security landscape — and Meta’s controversial “pay or consent” model — with Ron de Jesus, the world’s first Field Chief Privacy Officer. In our second episode, comedy content creator Derek Mitchell and TNW co-founder Boris discussed the value of humour in tech businesses. To celebrate the podcast’s launch, we’re also offering an exclusive discount on tickets for TNW Conference, which takes place in Amsterdam on June 19 and 20. You’ll find the offer hidden in each episode of TNW Backstage. Thanks for reading — and now, for listening too. Story by Thomas Macaulay Managing editor Thomas is the managing editor of TNW.

These 15 Mind-Bending Murals Turn the Mundane Into the Memorable See 15 images of superb street art from the Smithsonian Magazine Photo Contest Text by Tracy Scott Forson Photographs selected by Quentin Nardi May 16, 2025 6:00 a.m. There are many ways to explore a town or neighborhood, but one sure route to discovery is just taking a walk around and enjoying the street art. Community members and local governments often determine what and how the otherwise empty walls of a district will be decorated. Will the artwork honor a hometown hero, reflect the area’s commitment to education or the environment, depict a beloved park or historic building, or just offer bold, bright hues to lift visitors’ spirits? No matter what’s on the wall, it’s worth talking a look. See for yourself. A pedestrian walks by a mural depicting various tropical fruits in the Old Havana neighborhood of the Cuban capital.
