The acceleration is going to fairly instantaneous, somewhat similar to hitting the ground after falling off a roof. It can rearrange your innards.

I'm sure it will be fun to experience, but I hope it takes awhile for the thing to be released into the wild.

The average male human who would attempt such an adventure at a traffic light probably lacks the common sense to safely assure that he follows a protocol that might insure a minimal level of injury and death for people around him.

I can imagine that the NTSB, along with their fellow regulators in most semi-civilized countries will be leaping to place some regulation on that little beastie before the bloodbath begins.

True enough, Considering that it is still just 'Vaporware', so far.

While generally considered safe, there are enough cases of psychedelics causing mania and psychosis that more research is being done and it appears those with genetic vulnerabilities to schizophrenia or bipolar I disorders are most at risk.

JAMAQuestion Is there an association between psychedelic use and psychotic or manic symptoms in adolescents?

Findings In a cross-sectional study of 16 255 adolescent twins, psychedelic use was significantly associated with lower rates of psychotic symptoms when adjusting for other drug use. Psychedelic use was significantly associated with more manic symptoms for individuals with a higher genetic vulnerability to schizophrenia or bipolar I disorder than for individuals with a lower genetic vulnerability.

Meaning The findings suggest that psychedelic use may be associated with lower rates of psychotic symptoms but the association between psychedelic use and manic symptoms seems to be associated with genetic vulnerability.

In another forum, someone posted the following, which I had to share.



"Yep. Much like "the theory of evolution" is scientific fact. The "theory" is the explanation that makes it scientific fact."

Yes, but it's also important to be clear that evolution is a fact, while Darwin's theory of evolution by natural selection is a theory that in general terms is universally accepted (except by crackpots), but in fine detail is still open to ongoing debate and discovery and improvement.

Abusers of the power of information love to misrepresent this.

The Once-In-An-Eon Event That Gave Earth Plants Has Happened Again | IFLScience

We have found another example of primary endosymbiosis which is mostly what the article talks about, but the bigger news to me is that we found a eukaryote that fixes nitrogen on it’s own.

Currently we use petroleum products to get enough nitrogen in our fertilizer.

In the future, we can grow an algae that makes its own.

Also the nitro plants look like dodecahedrons apparently :)

NASA’s Voyager 1 Resumes Sending Engineering Updates to Earth – Voyager

Quote:
Voyager 1 stopped sending readable science and engineering data back to Earth on Nov. 14, 2023, even though mission controllers could tell the spacecraft was still receiving their commands and otherwise operating normally.
Quote:
The team discovered that a single chip responsible for storing a portion of the FDS [flight data subsystem] memory — including some of the FDS computer’s software code — isn’t working. The loss of that code rendered the science and engineering data unusable. Unable to repair the chip, the team decided to place the affected code elsewhere in the FDS memory. But no single location is large enough to hold the section of code in its entirety.

So they devised a plan to divide the affected code into sections and store those sections in different places in the FDS.
Prompting some entirely apt comments...

Devs sometimes talk about being "close to the metal" but there is no other software engineering team in the world right now that are simultaneously working as close to and as far away from the metal as the people keeping Voyager working.

The Evolutionary Origins of Clothing - The Atlantic

Quote:
Without clothing, humans would never have reached all seven continents. This technological breakthrough allowed our ancestors to live in Siberia during the height of the Ice Age, and to cross the frigid Bering Sea to the Americas some 20,000 years ago. But no clothing survives from this period. Not a single article of clothing much older than 5,000 years has ever been found, in fact. The hides and sinews and plant fibers worn by our ancestors all rotted away, leaving little physical trace in the archaeological record. Humans had to have worn clothing more than 5,000 years ago, of course. Of course! And in clever, indirect ways, experts have pieced together a surprising number of clues to how much longer ago.

When a wild orangutan in Indonesia suffered a painful wound to his cheek, he did something that stunned researchers: He chewed plant leaves known to have pain-relieving and healing properties, rubbed the juice on the open wound — and then used the leaves as a poultice to cover his injury.

"This case represents the first known case of active wound treatment in a wild animal with a medical plant," biologist Isabelle Laumer, the first author of a paper about the revelation, told NPR.

I sat in a lecture with some wildlife researcher whose name I can't remember. He recounted something about a bear spotted packing an abscessed tooth with willow for the 'Aspirin' properties. A hunter shot the bear as it was scraping the tree and that's how they figured out what it was doing, sadly for the bear.

They notch pig ears to keep track of pigs. One ear is litter number and one is pack number.

Each position can have one or two notches, so they count in base three!

This is awesome. If they can determine what caused the changes in gravitational force, we will be well on our way to creating anti-gravity technology!

A really cool example of physics in action as two bullets are shot into each other and explode into liquid galaxies, all in slo mo.

And if you wonder why all the 'health and safety gone mad!' discussion at the beginning, that might just be because the same guy had the rocket motor of an RPG partially explode on him while he was shouldering it and now they take safety a bit more seriously.

I’m not sure if we have talked about this before, but I thought if it recently when thinking how dumb the idea that there is a massive anti-Trump conspiracy

There was this one time that NASA thought they found evidence for life on mars via a meteorite found in Antarctica.

American museum of natural history link about the rock...

Now, they were probably wrong, but the germane part for this discussion is that the story leaked before the press conference.

NASA kept it quiet when it was a handful of scientists working on the rock, but within two days of the Whitehouse finding out, a dude told an expensive prostitute about it to impress her and the story leaked early.

https://www.texasmonthly.com/news-po...m-outer-space/

Each person in a conspiracy or a secret is a point of failure.

Some more amazing slo-mo, but this time it's not hehe bullets go smash but 'has that ever been filmed before' showing exactly how Cicadas (or at least this species) buzz.

While it's described as a 'pop-cap' the slo-mo shows that it's a section of arches that are pulled in sequentially and allowed to vibrate, before being released.
