NASA is building the first nuclear reactor-powered interplanetary spacecraft. How will it work?<\/strong> <\/h3>\n
Just before Artemis II began its historic slingshot around the moon, NASA revealed an even grander space travel plan. By the end of 2028, the agency aims to fly a nuclear reactor-powered interplanetary spacecraft to Mars. <\/p>\n
A successful mission would herald a new era in spaceflight\u2014and might just give the US the edge in the race against China. But the project remains shrouded in mystery. <\/p>\n
MIT Technology Review<\/em> picked the brains of nuclear power and propulsion experts to find out how the nuclear-powered spacecraft might work. Here\u2019s what we discovered. <\/p>\n

Coming soon: our 10 Things That Matter in AI Right Now<\/strong> <\/h3>\n
Each year, we compile our 10 Breakthrough Technologies list, featuring our educated predictions for which technologies will change the world. Our 2026 list, however, was harder to wrangle than normal. Why? We had so many<\/em> worthy AI candidates we couldn\u2019t fit them all in! <\/p>\n
That got us thinking: what if we made an entirely new list all about AI? Before we knew it, we had the beginnings of what we\u2019re calling 10 Things That Matter in AI Right Now. <\/p>\n
On April 21, we\u2019ll unveil the list on stage at our signature AI conference, EmTech AI, and then publish it online later that day. If you want to be among the first to see it, join us at EmTech AI or become a subscriber to livestream the announcement. <\/p>\n

MIT Technology Review Narrated: this company is developing gene therapies for muscle growth, erectile dysfunction, and \u201cradical longevity\u201d<\/strong> <\/h3>\n
In January, a handful of volunteers were injected with two experimental gene therapies as part of an unusual clinical trial. Its long-term goal? To achieve radical human life extension. <\/p>\n
The therapies are designed to support muscle growth. The company behind them, Unlimited Bio, also plans to trial similar therapies in the scalp (for baldness) and penis (for erectile dysfunction). But some experts are concerned about the plans. <\/p>\n
Find out why the trial has divided opinion. <\/p>\n

How refrigeration ruined fresh foo<\/strong>d<\/strong> <\/h4>\n
Bananas may not be chilled in the grocery store, but they\u2019re the ultimate refrigerated fruit. It\u2019s only thanks to a network of thermal control that they\u2019ve become a global commodity. And that salad bag on the shelf? It\u2019s not just a bag but a highly engineered respiratory apparatus. <\/p>\n
According to Nicola Twilley\u2014a contributor to the New Yorker and cohost of the podcast Gastropod\u2014refrigeration has wrecked our food system. Thankfully, there are promising alternative preservation methods. <\/p>\n
