Styropyro takes a an off the shelf 2 kilowatt fiber laser welder/rust remover and makes it a long range laser sniper weapon. There are a  number of issues… the mount is rickety and there’s no scope, primarily. But it’s remarkably capable, burning holes relatively quickly through steel plate and cinderblocks.

 

This would seem to indicate that a refined version with a better mount, better aim and a much faster reaction time/slew rate would serve as a dandy anti-drone system, easily mounted to something like a Hummer, small truck or as an add-on to armored vehicles. If one kid out in the boonies can do this on a YouTuber budget, I’m left to wonder why the Russian military *hasn’t* done it on a large scale.

Well, *some* of our jobs:

AI-created “virtual influencers” are stealing business from humans

Pink-haired Aitana Lopez is followed by more than 200,000 people on social media. She posts selfies from concerts and her bedroom, while tagging brands such as hair care line Olaplex and lingerie giant Victoria’s Secret.

Brands have paid about $1,000 a post for her to promote their products on social media—despite the fact that she is entirely fictional.

So… do we care?

If we are an influencer, sure. But this is one of the more socially worthless “jobs” out there. They add nothing to society; they learn few skills or trades useful for other more practical forms of employment. If all “influencers” were suddenly unemployed, there’d be tens/hundreds of thousands of talentless hacks suddenly dumped into the job market, competing for burger flipper roles against millions of new migrant voters. Sucks for them, I suppose.

 

But after the “influencers” will come the TV news anchors, actors, singers. Some have argued that people will prefer actual humans to AI for such things, but evidence is mounting to the contrary. And at some point soon (if not already)  it’ll be impossible to tell the difference, and *very* difficult to confirm that an AI isn’t real, especially if those controlling it want people to think said AI is a real person.

A common trope in science fiction is the discovery of “an element that does not appear on the periodic table.” This is of course nonsense… if the element has three protons, it’s lithium, full stop. And we’ve discovered – or invented – every element up to Element 118, Oganesson. These higher elements are quite unstable, generally having half lives of microseconds to minutes… but there is a suspected “island of stability” with some of these heavier elements if you can nail the isotopes correctly. Which nobody has.

But even if you can reliably manufacture the stable versions of these heavy elements on an industrial scale, the likelihood of them being useful to make spaceships or battle armor is low… and they’d still appear on the periodic table. Their physical properties probably won’t be that terribly interesting. Oganesson, for example, melts at a boring 52 C/125 F, and has a density of only 7.2 gm/cubic cm.

But Amazing Materials are terribly useful in science fiction. Witness Star Trek’s “dilithium,” a crystal that somehow or other allows matter-antimatter reactions that are controllable and useful. In Babylon 5 there was Quantium 40, necessary for the construction of jumpgates.  So what the hell are these?

 

I kinda recall that “Quantium 4o” was just bog-standard potassium-40 that had been close enough to a supernova to be *somethinged,* and changed at the quantum level *somehow,* resulting in a material that does Amazing Things.  How about dilithium? Well, dilithium is a real substance…. just a molecule with two lithium atoms bonded together in the gas phase. It’s clearly not the same thing as Trek’s “dilithium crystals,” and certainly not the later “trilithium resin” which has the interesting property that a few grams of the stuff can cause all fusion to cease in a star moments after it’s dropped in.

So… what the hell are Trekkian “dilithium,” or “vibranium” or “adamantium” or “byzanium” or “naquadah?” A century or more ago, fabulous new elements like “cavorite” could be thrown in without issue, because the list of known elements was massively incomplete. We can’t do that today.

In general, unless it’s important to the story, there’s neither need nor benefit to explaining such details in a story… it just exists. But now we know that there are no slots in the periodic table for new elements, so introducing them raises questions. So how to create actual new elements?

Honestly… I don’t know. But I’ve got an ill-formed probably crappy idea.

 

Take “dilithium.” Clearly “lithium” has something to do with it. Presumably *two* lithiums, given the name. If you simply stick two lithium atoms together, you get the previously mentioned uninteresting real-world “dilithium.” If you mash the lithiums together hard enough that the nuclei bond together, you no linger have lithium, you have carbon. This is just the way it is.

 

But while we can’t really posit new elements, we *can* posit the discovery, creation, utilization of new particles. We’re not done discovering such things. So *perhaps* there is a particle that can, say, replace neutrons in a nuclei, fullfilling the same function of gluing the protons into place. But they have a different effect on the electron shells. Perhaps to the point where two lithium nuclei so modified will actually stick together, but not actually fuse into carbon. Sort of a contact binary nuclei. Or these mystery particles are simply added to the neutrons and protons; being the same mass as a proton, if you add six of these new particles to a lithium atom you double the mass… thus di-lithium. These modified atoms would undoubtedly have very different properties from the regular stuff… properties the writer can simply declare. Adamantium, for instance, is a modification of helium; this turns it into a metal that, apparently, melts at a low temperature *once*, but when it solidifies it becomes not only insanely hard and tough, its melting temperature shoots way up.

 

In recent years one of the more popular fictional elements is “unobtanium” from “Avatar,” a room temperature superconductor. This *has* to be a new pseudo-element, rather than an alloy or compound. Because if it was the latter, a technological species with the ability to create antimatter-powered relativistic starships could simply synthesize the stuff. There’d be no need to mine it light years away. But if it was a material made from exotic particles… shrug.

So they’re coming for the night sky, too:

The Magellanic Clouds must be renamed, astronomers say

Anything and everything to erase any mention of the people who built the world. The wokies want to rename the Magellanic Clouds because by modern standards Magellan was not a great guy. But you don’t see them wanting to rename anything named by the Sumerians or Babylonians or the Arabs, do you.

A barnacle that attaches itself to female crabs and convinces said crab that it is her eggs so that the crab will take care of it, and help it distribute its own eggs. But it sometimes attaches itself to male crabs.In that case, it releases hormones that convince the male crab that it is female, sometimes to the point that the gonads actually flip sex.

Well, that’s horrifying.

But it’s also… well, huh. Hormones being fed into an organism without the organisms knowledge or consent, causing it confusion about its gender. one wonders if there might be some sort of analogies that can be drawn. Such as to chemicals in the water and food supply… birth control pills flushed down the toilet, entering the sewage treatment systems, *not* getting processed out and then dumped into the water supply. “Forever chemicals” added to plastic drinking bottles that mimic gendered human sex hormones, and which are now detectable in *rain.*

I guess this is kinda cool, a dress – at least the front side of one – composed of “scales” that can change from mirror-chrome to dull metallic on command. But even though it’s made of individual scales, it does not appear to be terribly flexible, and seems likely to be uncomfortable.

Still, if it could do more than just “shiny/matte,” but actually change colors, it seems like it might have a future. Specifically… plate *actual* steel scales with this material and make practical lamellar armor that can change color. That seems like it might be an interesting fashion for the future as society continues to get “enriched.” Shiny, perhaps even golden, armor when you’re out and about, and at the flick of a switch it turns matte black when the time comes to throw down.

Sure, here it seems to be pitched at the female market. But I suggest culturally appropriating the tech and making it the Must Have Man Product of the 2030’s.

Humanity, that is. In terms of our ability to scare the crap out of African wildlife.

Fear of the human “super predator” pervades the South African savanna

In short: cameras and speakers were set up near watering holes and a wide range of sounds, including lions and other predators, were played. Animals got the hell out of Dodge when the heard humans at a much greater rate than any other sound.

As a whole (n = 4,238 independent trials), wildlife were twice as likely to run (p < 0.001) and abandoned waterholes in 40% faster time (p < 0.001) in response to humans than to lions (or hunting sounds). Fully 95% of species ran more from humans than lions (significantly in giraffes, leopards, hyenas, zebras, kudu, warthog, and impala) or abandoned waterholes faster (significantly in rhinoceroses and elephants). Our results greatly strengthen the growing experimental evidence that wildlife worldwide fear the human “super predator” far more than other predators

Yay, I guess?

The “sounds of humans” turn out to be simple recorded conversations, male and female, in several languages. Not shouting, not angry, just “hey, how ya doin'” level chitchat. Rhinos and elephant just “nope” on out of there; other animals freak and dash. In contrast, lion sounds caused elephants to *attack* the speakers.

Yeah, I’m not sure I feel all that great about being the most terrifying thing on the planet.

Lots of people think we’re on the cusp of ditching fossil fuels in favor of an all-electric “renewable” and “green” world.  There are of course a vast number of problems with this… when they say “all electric” they almost never mean “all nuclear,” but instead want to pave over the fields with a million acres of solar panels and fill the seas with whale-confounding wind turbines. But there are issues beyond just what method will produce the volts and amps. For instance… all the batteries will need to be filled with metals dug out of the Earth; electric motors and a billion miles of power lines will need to be processed from all the copper we can scrape up. And the problem seems to be that at current resource extraction (i.e. mining) rates, we’re nowhere near able to deliver those materials.

So it seems we have a few options:

1) Turn Earth into a giant open pit. To hell with the environment… we need to save the environment!

2) Go all-electric… and just tell people to suck it up, they’ll learn to live with less. 15-minute cities will seem like the wildest dream of raving libertarians. Personal vehicles? Gone. Traveling any sort of distance at all? Prohibitively expensive to simply prohibited. Air conditioning? A myth from the Old Ones.

3) Asteroid mining. Everything we might need is available a million times over floating out in space; the effort to retrieve it will open spaceflight to mankind in a way never before dreamed, spreading civilization and terrestrial biology to the furthest regions of the solar system.

Which will it be?

Challenges and Bottlenecks for the  Green Transition

Methane levels in the atmosphere seem to be rising steeply. Since methane is a much more potent “greenhouse gas” than CO2, this could, perhaps, maybe, result in the end of the ice age that we’re currently in… within a few decades. The one good thing is that methane does not have a long lifespan, getting oxidized within a few years. But that’ll only help if the methane release – which seems to be coming from African wetlands – stops. of course, if the climate suddenly gets way hotter, the African wetlands releasing methane via decomposition of dead vegetable matter might turn into desert area, resulting in the eventual end of the methane release. Which means within a dozen or so years of that the methane will have burned out and the climate can descend back into good ol’ ice age status. *Proper* ice age, with glaciers covering continents and land bridges everywhere.  This will be aided by the fact that humans will have been largely wiped out at that point. Doubtless industrial civilization will have either moved off-world or simply been exterminated; and with no easy access to oil or coal anymore, anthropogenic CO2 emissions will be minimal.

Yaaaaaay.
