Submission + - A Cracked Piece of Metal Self-Healed in Experiment That Stunned Scientists (sciencealert.com)
While the observation is unprecedented, it's not wholly unexpected. In 2013, Texas A&M University materials scientist Michael Demkowicz worked on a study predicting that this kind of nanocrack healing could happen, driven by the tiny crystalline grains inside metals essentially shifting their boundaries in response to stress.

"5 inches square" is probably what they meant.
I've also seen it described as a cube, not unless it's 5x5x5

Does the media & social-media blackout of the NY Post's story on the Hunter Biden laptop qualify?
Most social-media suppressed the Post's initial tweets/etc, and wasn't widely reported elsewhere until after the election.

Like the right to buy hand grenades at Wal-Mart because you MIGHT do crime?
I think even most Americans are fine with that right being taken since they'd rather not have to worry if their neighbor is storing/using hand grenades for pest control.
99.99% of the population has limits on what types of weapons others can own. For some its any guns. For others its nukes. Some don't feel like its reasonable for neighbors to own high explosives for self-protection or hunting purposes. You have to draw that line somewhere. so don't act like any rules or regulations around owning potential weapons violates your rights.
Instead of hand-grenades, this change is more like restricting sales of plumbing parts & black-powder from Walmart, because you can easily assemble a tossable pipe-bomb with it.
Once plumbing supplies are banned, need to ban pressure-cookers (actually used in an attack).
Not sure where they would go from there; gasoline & glass bottles?
Something often overlooked: it's generally legal to own cannon in the USA.
How does that compare to a firearm or hand-grenade?

Even scarier than this is that tests have also shown traces of Bud Light, Michelob Ultra, Busch Light, and Miller Genuine Draft Light in Americans' urine.
Well at least there were no traces of beer.

Submission + - SPAM: Infrastructure Bill's Drunk Driving Tech Mandate Worries Some Privacy Advocates
Though the Department of Transportation has yet to put its foot down on the exact type of technology it will use for this program, the National Highway Traffic Safety Administration (NHTSA) and 17 automakers have been working on something called the Driver Alcohol Detection System for Safety (DADSS) since 2008. DADSS is exploring both a breath and touch-based system to detect whether or not a driver has a blood alcohol concentration (BAC) at or above 0.08%. The breath-based system aims to measure alcohol readings based on a driver’s breath with the goal of distinguishing between the driver and passengers. The touch-based system meanwhile would shine an infrared light through a driver’s fingertip to measure blood alcohol levels under the skin’s surface. [...]
The new mandate struck a positive note with some car safety groups, including Mothers Against Drunk Driving which has advocated for more detection tech in the past. “It’s monumental,” Alex Otte, national president of Mothers Against Drunk Driving told the AP. Otte went on to describe the package as the “single most important legislation” in the group’s history. At the same time though, the mandate has drawn concerns from safety experts and digital rights groups that warn driver monitoring technology could have knock-on privacy implications. In a letter sent last year by the American Highway Users Alliance, the organization urged support of the NHTSA’s DADSS Research Program but expressed concerns that the technology could potentially infringe on driver’s civil liberties.

Submission + - SPAM: John Carmack Issues Some Words of Warning For Meta and Its Metaverse Plans
Today, Carmack said, "The most obvious path to the metaverse is that you have one single universal app, something like Roblox." That said, Carmack added, "I doubt a single application will get to that level of taking over everything." That's because a single bad decision by the creators of that walled-garden metaverse can cut off too many possibilities for users and makers. "I just don't believe that one player—one company—winds up making all the right decisions for this," he said. The idea of the metaverse, Carmack says, can be "a honeypot trap for 'architecture astronauts.'" Those are the programmers and designers who "want to only look at things from the very highest levels," he said, while skipping the "nuts and bolts details" of how these things actually work.
These so-called architecture astronauts, Carmack said, "want to talk in high abstract terms about how we'll have generic objects that can contain other objects that can have references to these and entitlements to that, and we can pass control from one to the other." That kind of high-level hand-waving makes Carmack "just want to tear [his] hair out... because that's just so not the things that are actually important when you're building something." "But here we are," Carmack continued. "Mark Zuckerberg has decided that now is the time to build the metaverse, so enormous wheels are turning and resources are flowing and the effort is definitely going to be made."

What are you talking about? "Big Pharma" has dumped a ton of money into research on Alzheimer's drugs, developed a number of prospective treatments/preventatives, some made it to human trials. Most flamed out at some point during human trials. At least 1 worsened the symptoms. Turns out we don't understand Alzheimers as well as we thought. I don't think researchers even agree if beta-amyloid is a cause or a symptom of Alzheimers (some drugs helped reduce beta amyloid but don't seem to help the symptoms).

Simple solution for you: buy a metronome, fasten step-tracker to it, then turn on metronome.
Occasionally stop the metronome to read the step-count, adjust the speed & time to hit your step-target.
Repeat daily or weekly to hit your target, then share the data with your plan.
Meanwhile you can watch TV, read a book, relax in a hot-tub, etc.
If a metronome won't swing with tracker attached, perhaps a paint-shaker?
Or build something with motorized Lego or Erector set.
