The fact that it makes a big cloud around a galaxy or cluster rather than collapsing puts a lot of constraints on what it can do.

For more info, you'll have to go to someone who knows more about it than what I've read on science-news websites.

Dark energy is a real puzzle. As I understand it, it's too weak by a factor of 10^30 or 10^60 in comparison from what we should expect the known vacuum energy would cause. You see this mentioned very occasionally, but most treatments of DE that a layman runs across just ignore it in favor of wringing their hands over some issue that is trivial in comparison.

Some boffin cam up with that idea, but they rule it out because DM apparently doesn't interact with itself (very much) other than by gravity, so it can't clump up tight like a star or a planet or a living thing. (Something to do with shedding energy, IIRC.)

But it's a cool idea. If I were a novelist I'd run with it.

Submission + - Chinese study claims stem cell therapy reversed type 2 diabetes in patient (business-standard.com)

AmiMoJo writes: In a medical breakthrough, researchers in China have reported the world’s first successful reversal of type 2 diabetes using stem cell therapy. By restoring the body’s natural ability to produce insulin, the treatment moves beyond lifelong symptom management and signals a future in which diabetes may no longer be a permanent condition. Researchers in China used advanced stem cell technology to generate insulin-producing pancreatic cells in the laboratory and then transplanted these into a patient with type 2 diabetes. After receiving the treatment, the patient reportedly no longer needed insulin injections or diabetes medications to control blood sugar levels.

Submission + - Scientists Turn Plastic Waste Into Edible Cookies (futurism.com)

fjo3 writes: In the event we turn all arable land on this planet into a barren heath incapable of growing food, humankind may have to resort to reaping what we sowed by eating our own plastic pollution.

A team of researchers at Southern Illinois University Carbondale just demonstrated that this was possible by using specially engineered yeast to create tasty — and yes, edible — cookies which they 3D printed out of plastic waste.

The yeast breaks down the components of plastic compounds and agricultural byproducts like discarded plant stalks into proteins, fats, acids, and flavorings that we can eat. When these are combined together, the mixture is fed into a 3D printer that spits out cookies of any desired shape.

Submission + - OpenAI and Google Move Into K-12 Classrooms with New Kid-Friendly AI Offerings

theodp writes: "OpenAI announced on Tuesday 'ChatGPT for Teens'", the NY Times reports, "a new mode in which the chatbot automatically limits some conversations to better protect young users, as scrutiny grows over the harmful effects of artificial intelligence." OpenAI added that it's also teaming with tech-backed nonprofit CodeAI to 'prepare the first AI generation', announcing a 'signature partnership' that it says will "give students and educators access to tools and resources that will help them learn how to use and benefit from AI [...] helping teens understand how AI works, direct it, question it, and create with it—with teachers playing a meaningful role in shaping how AI enters the classroom." Separately, CodeAI said it and OpenAI will be "helping students build foundational AI literacy" via the Hour of AI, through which it said "OpenAI and CodeAI will introduce millions of students to the basics of using AI thoughtfully and responsibly."

OpenAI's ChatGPT for Teens announcement came just days after the NY Times reported that Google turned on Gemini AI for K-12 students using its Google Classroom, a learning management system for posting assignments and turning in schoolwork that's used by 150+ million students and teachers worldwide. A new Gemini tab within Classroom will allow students of all ages to seek AI help on math problems and writing assignments. They can also generate course aids like study guides, quizzes and flashcards, as well as produce images. Last September, Google CEO Sundar Pichai briefed the White House on the tech giant's efforts to get Gemini for Education in 'every high school in America', which he noted "includes $3 million to Code.org [since rebranded as CodeAI] to transform its [K-12] curriculum and integrate new AI features." And in December, Google.org kicked off the inaugural 'Hour of AI' by announcing "over $5 million in new Google.org funding to bolster computer science teaching in the age of AI." The 5-day event during CS Education Week saw 13+ million schoolkids take AI tutorials, including Google's AI Quests offering.

The moves by Google and OpenAI in advance of children's return to classrooms for the 2026-27 school year further escalate the race among U.S. tech giants to train students on their AI tools. They also come just ahead of next month's release of NYT journalist Natasha Singer's Coding Kids: Big Tech's Battle to Remake Public Schools, "the inside story of how Big Tech catalyzed, co-opted, and ultimately came to capture computer science and AI education in America."

But even calling it "evidence" sets up the bias. Destroying data for possible crime is a way to put it, but then that seems like minority report.

Destroying something law enforcement believes is evidence in that moment is literally Obstruction of Justice, and destroying evidence is literally a crime specifically for that reason. There really isn't much grey area here.

You're free to do whatever you want to your own data (subject to previous judicial order), but the moment a legitimate authority -- whether state or local law enforcement or a Federal agency like Customs and Border Control -- indicates that your data/property is subject to search or review, destroying such data is literal obstruction and will get you as much of a charge as if you flushed evidence away while a cop was asking for it.

If the LEO or agency is overstepping their bounds, once you've been put on notice that you're the subject of an investigation the proper remedy is judicial review and a lawsuit. You don't get to #resist, and you certainly don't get to blow up your phone just because someone taught you this One Weird Trick.

Have fun in jail, bro.
