Mushrooms mixed into meatballs, smart glasses help blind people read: today's tech news is refreshingly down-to-earth

This is the November 4, 2026 edition of The Download briefing from MIT Technology Review. I've selected a few noteworthy stories and added extra context, no mindless hot takes, just tangible real-world progress.

Mushrooms blended into meatballs: 92% of students didn't notice the difference

In fall 2025, Jeff Dodge ran a taste test of spaghetti meatballs for students in a campus cafeteria. 92% of the students who tried the dish said they wanted it added to the regular menu. Almost no one guessed the meat was mixed with mushrooms.

The product line, called 50/Cut from food startup Joyn, comes in meatball, burger patty, and ground meat formats. The idea is straightforward: to get people to eat less red meat, don't force them to cut it out entirely. Replace part of the meat with plant-based protein without sacrificing taste or texture. It's not the flashiest approach in the climate debate, but it's far more aligned with how regular consumers actually behave.

Retinal implant lets over 80% of trained users read again

Geographic atrophy is an advanced form of age-related macular degeneration that affects more than 5 million people, killing off retinal cells and leaving patients with permanent central vision loss. Previously no treatment existed that could restore usable vision.

The PRIMA system combines a retinal implant with camera-equipped smart glasses to compensate for the central blind spot. After a short training period, more than 80% of test subjects could read, complete crossword puzzles, and use a smartphone. Check the original article for full technical details and limitations of the technology.

The agentic web: browsers could end up running in the background

Back in 2001, 10 years after Tim Berners-Lee invented the World Wide Web, he laid out a vision: the internet would be navigated by autonomous software agents that handle our requests for us, without us having to manually fiddle with browsers and search engines. At the time it sounded like pure science fiction.

25 years later, AI agents already sort our inboxes, order our groceries, and access our bank accounts. This new paradigm is called the agentic web. No one can say for sure yet if it will relegate the human-facing public web to a forgotten corner.

The agentic web is already here

Today's must-read stories

1. The US midterm elections brought major setbacks for tech billionaires. The results are expected to bring stricter scrutiny of AI development and data center construction. Elon Musk poured millions of dollars into Texas election races, and every candidate he backed lost. Multiple winning candidates have pledged to impose limits on new data center builds. Stock index futures dropped following the Democratic landslide, and tech-aligned left-wing groups say they are ready to "wipe the floor" with the previous industry-friendly policy framework. CNBC

2. Google is turning off access to Search for schools that refuse to adopt its AI tools. The company says AI and search can no longer be separated. Critics accuse Google of strong-arming K-12 and higher education institutions into adopting its AI products. CNN

3. The Binance hacker used fake job interviews on LinkedIn to target engineering employees. TechCrunch reports the heist is a record-breaking $6.3 billion theft, and researchers warned about this exact social engineering tactic years ago. TechCrunch

4. 3M will pay $7.35 billion to settle lawsuits over PFAS, the "forever chemicals" found in firefighting foam. New technology may soon be able to fully remove PFAS contaminants from drinking water. WSJ

5. Finland has opened its new nuclear waste repository, designed to operate safely for 100,000 years, with spent nuclear fuel stored 400 meters underground. New Scientist

6. Russia is planning to build underground data centers to avoid damage from Ukrainian drone strikes. Ars Technica

7. Anthropic is developing a system called FlashProve that proves the identity of AI models, using cryptography to verify the provenance of model outputs. TechCrunch

8. Old decommissioned jet engines are being repurposed to power data centers, with environmental activists warning the practice will lead to a sharp rise in pollution. NYT

9. Dinosaur blood cells have been discovered in fossilized remains for the first time, opening new doors for research on ancient biomolecules. Guardian

10. The wild dogs of Chernobyl appear to be evolving, with scientists identifying unique genetic differences linked to DNA repair and immune function. Wired

Quote of the day

"Turns out my election-interfering space lasers didn't work this time," Elon Musk joked on X, trying to brush off the crushing defeat of all the Republican candidates he backed with record-breaking funding in the US midterms. It's a light quip, but the bill he's left with is far from trivial. Original post

One more thing: these charts tell you exactly where AI stands right now

AI news moves at breakneck speed – one week it's a gold rush, the next a popping bubble, then panic over job losses, then revelations that even the best models can't read a simple clock. Stanford's 2026 AI Index is the industry's annual report card that cuts through all the noise.

The report covers US-China tech competition, model breakthroughs, public sentiment around AI, and its impact on employment. Here are all the key findings.
