Studying vanishing dietary diversity before it is lost: the World Diet Initiative
Nature Medicine, Published online: 15 July 2026; doi:10.1038/s41591-026-04520-5
Heritage diets are disappearing as food systems homogenize; their effects on immunity, metabolism and host–microbiome biology remain poorly understood. The World Diet Initiative offers a framework to document heritage diets and investigate their effects before they are lost.

The Download: a useful quantum machine and a record-breaking subsea tunnel
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
PsiQuantum has a plan to make a massive quantum computer out of light
The machine that could change the world will be housed in a room that looks like a data center crossed with an ice cream factory.
Inside, some 100 stainless-steel cabinets each hold hundreds of chips. On those chips, thousands of light particles will fly through a maze of optical switches and beam splitters. Each photon must be accounted for, because precisely measuring where it ends up will help answer questions that current computers might take millions of years to solve.
This computer, as described, does not exist. It’s the brainchild of a company called PsiQuantum, founded in 2016 by four physicists from UK universities. In a crowded field of deep-pocketed competitors with similarly fantastical visions, the company aims to be the first to build a useful quantum machine.
Read the full story on the company’s quest.

MIT Technology Review Narrated: inside the world’s deepest and longest subsea road tunnel
—Niall Firth
I’m currently around 1,000 feet beneath the North Sea, in a dark, dank cave. It smells weird. And I’m increasingly aware of the pressure from millions of tons of seawater just above my head.
I’m under the iconic fjords of Norway to visit what will soon become the world’s longest and deepest subsea road tunnel—an exceptional engineering feat that will carry drivers deep beneath the North Sea.
I’m here to understand how you make a 16.6-mile highway that sits 1,280 feet below the sea at its deepest point. And also—at a time when it can feel hard to get anything done—to reassure myself that ambitious engineering is still possible. That we can still make things.
This is our latest story to be turned into an MIT Technology Review Narrated podcast, which we publish 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.

Hackers made death threats against this security researcher. Big mistake.
In April 2024, an anonymous hacker began posting death threats on Telegram and Discord channels aimed at a cybersecurity researcher named Allison Nixon. It wasn’t long before others piled on. Someone shared AI-generated nudes of her.
They targeted Nixon because she had become a formidable threat. As chief research officer at the cyber investigations firm Unit 221B, named after Sherlock Holmes’s apartment, she had built a career tracking cybercriminals and helping get them arrested.
For years, Nixon had lurked quietly in online chat channels or used pseudonyms to engage with perpetrators and bring them to justice. Now, she resolved to unmask the people behind the death threats—and take them down for crimes they admitted to committing.
Find out why they learned to regret their choice of target.

What to know about the parasitic diarrhea outbreak
Get your daily dose of health and medicine every weekday with STAT’s free newsletter Morning Rounds. Sign up here.
Good morning. I dedicate the first item in today’s newsletter to a friend who is suffering from what she suspects to be cyclosporiasis. Feel free to forward this email to your friends who need information but are scared to wade through online discussions on the outbreak.
STAT+: Medicare Advantage insurers face new bipartisan scrutiny over AI and care denials
Sens. Richard Blumenthal (D-Conn.) and Josh Hawley (R-Mo.) are calling on the nation’s largest Medicare Advantage insurers to provide internal records and detailed information on their use of artificial intelligence to block rehabilitative care.
The lawmakers’ request — a moment of bipartisan scrutiny on a controversial federal health care program — comes just one month after a government investigation unearthed a continuing pattern of denials within Medicare Advantage.
In letters provided to STAT, Blumenthal and Hawley told executives at UnitedHealth Group, Humana, and CVS Health that recent findings by the Office of the Inspector General for the Health and Human Services Department undercut their companies’ claims to have reduced barriers to crucial medical services.
Opinion: Why we still don’t know what foods are the source of the cyclospora outbreak
As of Tuesday, a parasite called cyclospora has sickened nearly 7,000 people in 34 states so far this summer. On Monday, Michigan health officials announced their first potential source: lettuce and salad greens. Their advice was sound: Buy whole heads, discard the outer leaves, wash what’s left. But it landed after vinegar rinses and peeling rituals had circulated online for weeks.
Michigan’s announcement was careful: Lettuce keeps surfacing in interviews, other foods cannot be ruled out, and no grower or supplier has been named. That is what a “potential source” is — a hypothesis strong enough to keep pulling on. Weeks into one of the largest cyclosporiasis surges on record, we still cannot answer the question people need answered: Which food is making us sick? The Centers for Disease Control and Prevention cannot yet say whether this is one outbreak with a common source or several unconnected clusters.
STAT+: Swing Therapeutics acquired by medical VR platform XR Health
Swing Therapeutics, developer of a Food and Drug Administration-cleared digital treatment for fibromyalgia, has been acquired by medical virtual reality company XR Health.
Swing is XR Health’s sixth acquisition in the last two years and finds the VR developer taking a new business direction as it aims to be a go-to source of digital treatments for disease. The terms of the deal were not disclosed because, as XR Health CEO Eran Orr explained, “it won’t be the last” acquisition for the company.
XR Health, Orr claimed, has dozens of different apps on its platform currently and delivered a million user sessions in 2025. Offerings include a range of meditation and cognitive behavioral therapy-based VR experiences targeted at mental health issues, pain, hot flashes, and more. XR Health’s large packages of VR treatments are registered with the FDA but not cleared.
Flood of comments on White House grantmaking overhaul is largely negative, analysis shows
An analysis of a torrent of public comments submitted on a White House proposal to change the way federal contracts and grants are doled out shows a widespread rebuke of the potential change by scientists and others.
The analysis, done by researchers at the University of North Carolina at Chapel Hill in partnership with STAT, used a large language model to classify whether a comment was supportive or in opposition and to identify themes mentioned in comments. It found that about 95% were in opposition and just 1% supported the proposed changes to the “Uniform Guidance.” A total of 496,769 public comments were submitted before the deadline of Monday at midnight, and an analysis of the 52,322 comments that have been posted in full show an overwhelming rebuke of the proposal.
