Your daily dose of what’s up in emerging technology

By Rhiannon Williams • 10.22.25

Hello! Today: the latest edition of MIT Technology Review magazine is now live—and it’s all about the human body, and the researchers working to tweak it. Plus: this week’s MIT Technology Review Narrated podcast takes a look at how Starlink is changing how Antarctica connects with the outside world.

Introducing: the body issue

We’re thrilled to share the latest edition of MIT Technology Review magazine, digging into the future of the human body, and how it could change in the years ahead thanks to scientific and technological tinkering.

The below stories are just a taste of what you can expect from this fascinating issue. To read the full thing, subscribe now if you haven’t already.

+ A new field of science claims to be able to predict aesthetic traits, intelligence, and even moral character in embryos. But is this the next step in human evolution or something more dangerous? Read the full story.

+ How aging clocks can help us understand why we age—and if we could ever reverse it. Read the full story.

+ Instead of relying on the same old recipe biology follows, stem-cell scientist Jacob Hanna is coaxing the beginnings of animal bodies directly from stem cells. But should he?

+ The more we move, the more our muscle cells begin to make a memory of that exercise. Bonnie Tsui’s piece digs into how our bodies learn to remember.

MIT Technology Review Narrated: How Antarctica’s history of isolation is ending—thanks to Starlink

“This is one of the least visited places on planet Earth and I got to open the door,” Matty Jordan, a construction specialist at New Zealand’s Scott Base in Antarctica, wrote in the caption to the video he posted to Instagram and TikTok in October 2023.

In the video, he guides viewers through the hut, pointing out where the men of Ernest Shackleton’s 1907 expedition lived and worked.

The video has racked up millions of views from all over the world. It’s also kind of a miracle: until very recently, those who lived and worked on Antarctic bases had no hope of communicating so readily with the outside world. That’s starting to change, thanks to Starlink, the satellite constellation developed by Elon Musk’s company SpaceX to service the world with high-speed broadband internet.

This is our latest story to be turned into a MIT Technology Review Narrated podcast, which we’re publishing each week on Spotify and Apple Podcasts. Just navigate to MIT Technology Review Narrated on either platform, and follow us to get all our new content as it’s released.

The quest to protect farmworkers from extreme heat

Even as temperatures rise each summer, the people working outdoors to pick fruits, vegetables, and flowers have to keep laboring.

The consequences can be severe, leading to illnesses such as heat exhaustion, heatstroke and even acute kidney injury.

Now, researchers are developing an innovative sensor that tracks multiple vital signs with a goal of anticipating when a worker is at risk of developing heat illness and issuing an alert. If widely adopted and consistently used, it could represent a way to make workers safer on farms even without significant heat protections. Read the full story.
