The first human test of a rejuvenation method will begin “shortly” 

When Elon Musk was at Davos last week, an interviewer asked him if he thought aging could be reversed. Musk said he hasn’t put much time into the problem but suspects it is “very solvable” and that when scientists discover why we age, it’s going to be something “obvious.” Not long after, the Harvard professor […]

Measles is surging in the US. Wastewater tracking could help.

This week marked a rather unpleasant anniversary: It’s a year since Texas reported a case of measles—the start of a significant outbreak that ended up spreading across multiple states. Since the start of January 2025, there have been over 2,500 confirmed cases of measles in the US. Three people have died. As vaccination rates drop

Three technologies that will shape biotech in 2026

Earlier this week, MIT Technology Review published its annual list of Ten Breakthrough Technologies. As always, it features technologies that made the news last year, and which—for better or worse—stand to make waves in the coming years. They’re the technologies you should really be paying attention to. This year’s list includes tech that’s set to

Base-edited baby: 10 Breakthrough Technologies 2026

Kyle “KJ” Muldoon Jr. was born with a rare genetic disorder that left his body unable to remove toxic ammonia from his blood. He was lethargic and at risk of developing neurological disorders. The condition can be fatal.  KJ joined a waiting list for a liver transplant. Then Rebecca Ahrens-Nicklas and Kiran Musunuru at the

A new CRISPR startup is betting regulators will ease up on gene-editing

Here at MIT Technology Review we’ve been writing about the gene-editing technology CRISPR since 2013, calling it the biggest biotech breakthrough of the century. Yet so far, there’s been only one gene-editing drug approved. It’s been used commercially on only about 40 patients, all with sickle-cell disease. It’s becoming clear that the impact of CRISPR

America’s new dietary guidelines ignore decades of scientific research

The new year has barely begun, but the first days of 2026 have brought big news for health. On Monday, the US’s federal health agency upended its recommendations for routine childhood vaccinations—a move that health associations worry puts children at unnecessary risk of preventable disease. There was more news from the federal government on Wednesday,

Job titles of the future: Head-transplant surgeon

The Italian neurosurgeon Sergio Canavero has been preparing for a surgery that might never happen. His idea? Swap a sick person’s head—or perhaps just the brain—onto a younger, healthier body. Canavero caused a stir in 2017 when he announced that a team he advised in China had exchanged heads between two corpses. But he never

Researchers are getting organoids pregnant with human embryos

At first glance, it looks like the start of a human pregnancy: A ball-shaped embryo presses gently into the receptive lining of the uterus and then grips tight, burrowing in as the first tendrils of a future placenta appear.  This is implantation—the moment that pregnancy officially begins. Only none of it is happening inside a

This company is developing gene therapies for muscle growth, erectile dysfunction, and “radical longevity”

At some point next month, a handful of volunteers will be injected with two experimental gene therapies as part of an unusual clinical trial. The drugs are potential longevity therapies, says Ivan Morgunov, the CEO of Unlimited Bio, the company behind the trial. His long-term goal: to achieve radical human life extension. The 12 to

Take our quiz on the year in health and biotechnology

In just a couple of weeks, we’ll be bidding farewell to 2025. And what a year it has been! Artificial intelligence is being incorporated into more aspects of our lives, weight-loss drugs have expanded in scope, and there have been some real “omg” biotech stories from the fields of gene therapy, IVF, neurotech, and more.
