Japan scientist synthesizes meat from human feces

Add as a preferred source on Google

Somehow this feels like a Vonnegut plotline: population boom equals food shortage. Solution? Synthesize food from human waste matter. Absurd yes, but Japanese scientists have actually discovered a way to create edible steaks from human feces.

Mitsuyuki Ikeda, a researcher from the Okayama Laboratory, has developed steaks based on proteins from human excrement. Tokyo Sewage approached the scientist because of an overabundance of sewage mud. They asked him to explore the possible uses of the sewage and Ikeda found that the mud contained a great deal of protein because of all the bacteria.

The researchers then extracted those proteins, combined them with a reaction enhancer and put it in an exploder which created the artificial steak. The “meat” is 63% proteins, 25% carbohydrates, 3% lipids and 9% minerals. The researchers color the poop meat red with food coloring and enhance the flavor with soy protein. Initial tests have people saying it even tastes like beef.

Inhabitat notes that “the meatpacking industry causes 18 percent of our greenhouse gas emissions, mostly due to the release of methane from animals.” Livestock also consume huge amounts of resources and space in efforts to feed ourselves as well as the controversy over cruelty to animals. Ikeda’s recycled poop burger would reduce waste and emissions, not to mention obliterating Dante’s circle for gluttons.

The scientists hope to price it the same as actual meat, but at the moment the excrement steaks are ten to twenty times the price they should be thanks to the cost of research. Professor Ikeda understands the psychological barriers that need to be surmounted knowing that your food is made from human feces. They hope that once the research is complete, people will be able to overlook that ugly detail in favor of perks like environmental responsibility, cost and the fact that the meat will have fewer calories.

Waste not, want not.

Tiny robots could shrink weeks of heart infection treatment into a single day
Forget open-heart surgery, because these rice-sized robots take the express route to your heart.

Treating a heart infection is no walk in the park. Patients often spend weeks on IV antibiotics, and if that fails, open-heart surgery enters the picture. Johns Hopkins University engineers may have found a better way.

The team has developed magnetic “millirobots” that are about as wide as a pencil tip and roughly as long as a grain of rice. As detailed in their study published in Advanced Materials Technologies, the robots are designed to deliver medicine directly to infected heart tissue.

Meta goes toe-to-toe with the big boys as it launches Muse Wonder AI models

It's raining frontier AI models. Soon after Anthropic set alarm bells ringing with its Claude Fable model at the summit of AI peformance, OpenAI answered with GPT-6 Astra. Not one to be left behind, Google released Gemini 4 Argon. The race is now getting hotter as Meta enters the fray with two new AI models in the Muse series: Wonder and Wonder Full. Cheesy naming aside, these Meta AI models mean business, or at least that's what the benchmark figures suggest. More importantly, these AI models are already making their way to Muse users.

AI can’t tell if you’re gay or straight, but it thinks it knows what both look like
AI knows it shouldn't judge a face, but apparently, drawing one is a different story.

We've all been told not to judge a book by its cover, and you'd think AI would follow that rule, too. Ask an AI chatbot to guess someone's sexual orientation just by looking at their face, and it'll likely tell you that there's no reliable way to know. But what happens when you ask that same model to change someone's appearance to match a particular sexual orientation? Well, that's where things get uncomfortable.

A new study, accepted for presentation at the 2026 Conference on Empirical Methods in Natural Language Processing, found that AI models from OpenAI and Google can be inconsistent when handling sensitive personal characteristics. They might refuse to make assumptions about someone based on their appearance, but when asked to generate those same assumptions visually, the results tell a very different story.
