What new materials are there?


 
New hydrogen catalyst:


—so that's how 2001's Discovery got away with a thin spine-its nuclear light-bulb was a two-fer! :)


-also on the sight was a blurb on Navier-Stokes called "Mathematicians resolve a longstanding open problem for the so-called 3D Euler singularity."

Other articles of note are: "Physicists strike gold, solving 50-year lightning mystery,"
"Researchers find a sweet new way to print microchip patterns on curvy surfaces,"

"A radical new approach in synthetic chemistry," and

"Researchers suggest that wormholes may look almost identical to black holes."

Charles V's code has been broken, BTW.

Has some blurb from the linked site come over into your post? It seems a bit disjointed.
 
I typed that with my other work phone. Maybe this one will let me space it out better.

Advances

Matterverse


New alloy
the new material uniquely displayed a low Young's modulus of <25GPa and a large Poisson's ratio of 0.47. In other words, the material is highly elastic, even when exposed to small amounts of stress, and is remarkably strong.

Now that's a big one--metal that gets tougher as it gets colder? Wow!

From that site:

"The toughness of this material near liquid helium temperatures (20 Kelvin, -424 Fahrenheit) is as high as 500 megapascals square root meters. In the same units, the toughness of a piece of silicon is one, the aluminum airframe in passenger airplanes is about 35 , and the toughness of some of the best steels is around 100. So, 500, it's a staggering number," said research co-leader Robert Ritchie, a senior faculty scientist in Berkeley Lab's Materials Sciences Division and the Chua Professor of Engineering at UC Berkeley.

Could go in "Automotive Fun', I suppose, but despite all the metaverse and augmented reality pokemon stuff, it's the skin that's interesting. (Having a 'Get off my lawn!' moment, I can't think of any worse car to ride in than one that perpetually bombards me with apps and 'cute' animations. Is BMW turning into the Sirius Cybernetics Corporation?)

I've mentioned BMW trying out monochromatic version of this but now they've gone full colour. The palette would make Andy Warhol puke, or the rapid changes would cause him to have a grand mal seizure.


Anyway, it may have wider applications. In this form it won't stand the rigours of many real-world situations (such as combat) and I wonder how one of these cars will look after being parked in UV-rich sunlight for a year.

That said, a more robust version of the basic concept has been worked on, depending on replaceable standardised cells.

If the Universe Is Teeming with Aliens ... WHERE IS EVERYBODY?: Seventy-Five Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life (Science and Fiction) 2nd ed. 2015 Edition

by Stephen Webb (Author)

I read the first edition and was unimpressed.

He presented each explanation with the requirement that it be 100% effective on its own - that is, the zoo would have to have perfect guards, the berserkers would make the Daleks look like hippies, the Vogon bureaucracy would be effective etc. If they couldn't reach the 100% bar, then they had to be false according to his reasoning.

However, only a few were exclusive, meaning that more than one, indeed many mechanisms could be at play simultaneously. The cumulative effect of several less-than-perfect mechanisms would still be our complete isolation.

Webb didn't allow this and worse, he actually used a cumulative argument at the end - a variant on the Drake Equation to claim that technological life was simply too unlikely anyway. So there.

I don't think he was aware of the logical inconsistency.

- Our Galaxy is old enough to house civilizations that may be BILLIONS of years older than Earth.

In my opinion, the search for ET is poorly raised because, in short, it all depends on what we are looking for, how we are looking for it and what we hope to find.

Alien life is very possible due to the abundant variety of amino acids found by radio astronomers in interstellar clouds.

Intelligent alien life is statistically probable (Frank Drake equation).

Intelligent alien life interested in interstellar travel is less probable. It would have to be an energy rich culture, with the curiosity of a young civilization (in ours, it only lasted 40 years) and with the conquest spirit of some mad individuals. Difficult that all these factors coincide in the same society.

Chronologically speaking it is not very probable that two civilizations evolve at the same time and are ready for contact. A few thousand years are not much for a galaxy and a too long period for the UN, NATO, or the Third Reich.

There is the theory of cyclical history as proposed by Oswald Spengler and developed in fiction by A.E. van Vogt, Robert A. Heinlein, and Isaac Asimov. According to that theory, a civilization can be ‘young’ and even barbaric, and yet high-tech, since civilizations comes and goes, though most of the technological progress done by the previous civilizations are not forgotten.

Humanoid form is the result of hazard and millions of random mutations. The reason why the Hollywood ETs are humanoid is economic, a guy disguised with a rubber head. Actors wish to show their faces to increase their popularity and for that reason the aliens in the TV series are almost human.

If there are intelligent creatures somewhere in the cosmos, the only sure thing about them is that they will not look like us.

ET may have any shape except that of a pretty girl: Gestalt organisms, smart clouds, natural computers integrated by metallic particles in a magnetic field, flying plants, organic film on water, metallic skeleton creatures, giant sponges, planetary wide fungus, energy balls, solar parabolas, insects evolved in low gravity, organisms made of neutron matter, alive comets, wave vortices, thinking crystals and six meters long caterpillars may be shaped by the evolutionary pressures of another world.

They may swim in liquid methane oceans, breathe a mixture of chlorine and ammonia, be able to see the heat, communicate by means of luminous pulses, or develop senses that we cannot understand such as telepathy, especially useful to small Gestalt organisms such as colonies of insects with a powerful collective mind.

They could be like gigantic jellyfish floating in the toxic atmosphere of their world, or worm-like beings carrying an incomprehensible underground existence, or aquatic creatures that have evolved into an ocean-planet, with no possibility of access to fire, metals and technology but with great abstract intelligence and interesting musical culture.

They may live in space cities, away from the inconveniences of a planetary surface with earthquakes, volcanoes, hurricanes, tsunamis, and problems with local wildlife, or simply live in the interstellar space feeding on ionizing radiation.

Perhaps biological intelligence is just a transient phenomenon in evolution. A very advanced society can achieve immortality by transferring the personality and memory of its individuals to eternally self-repairable quantum devices, as time crystals or spheres of energy. In that case they would prefer to inhabit the cold outer regions of the Galaxy and even intergalactic space, away from stellar disturbances, supernovae, and gravitational waves, which could cause interference in their computer systems.

They may despise societies made up of biological organisms and avoid any contact, as we do with mites. Why would those higher entities bother to establish a communication with us? What could we tell them?
 
On that note, next month's cover story for Scientific American and the article online (usually paywalled, but you can get your first couple for the month free.

Robots with voxels and plastic with metal backbone

New alloys
Li says the team have already used these findings to make an aluminum alloy that is 50% stronger than alloys containing the same amount of copper that are currently available commercially.

"This is not an easy task for aluminum," he says.

While the materials Li and colleagues are making in the lab are still far from application in industry, alloys that retain their strength at high temperatures are useful in engines and for other applications where the components get hot.


Now a breakthrough for hydrogen---

Rubbia wanted very thin channels for Americium:
In their paper, Yigal Ronen and his colleagues demonstrate that Am-242m can sustain nuclear fission reactions within films less than a thousandth of a millimeter thick. Not only do such thin films make for relatively light nuclear reactorsa necessary condition for efficient interplanetary cruisingbut they also allow the high-energy, high-temperature fission products to escape, freeing them for use in propulsion. More common nuclear materials don't afford fission products such liberty: uranium-235 and plutonium-239 both require large fuel rods, which absorb the reaction fragments.

Looks like he got his wish in some respects

“We found it lowers risk. After these stress analyses, we find [that] the parts generated by the algorithm don’t have the stress concentrations you have with human designs. The stress factors are almost ten times lower than parts produced by an expert human,” McClelland explained.

According to Ryan McClelland, who pioneered the design of these parts, these evolved structures can save up to two-thirds of the weight compared to standard components and reduce the risk of failure.
