It's not about the specific "BioPykrete" example, it's the technique that's interesting: using proteins to bridge dissimilar materials in composites. It's using them in a way that's sort of like how an emulsifier lets you bridge lipophilic and hydrophilic compounds

Think, say, plastic-ceramic or plastic-metal composites. We can do these today (say, Colorfabb Bronzefill 3d printing filament), but the addition of ceramic or metallic particles makes the material properties generally worse, not better. The plastic just does not bond well to the particles; you have to significantly limit the percentage of metal or ceramic in your mix, and it makes them much harder to work. But what if they *did* bound well? You could easily produce materials with significantly boosted strength, abrasion resistance, etc, but with the low-temperature workability of plastics (note: they'd probably have to be thermoset, not thermoplastic, or low-temperature thermoplastics; proteins have heat survivability limits)

And why stop at metals and ceramics? You could literally just use "dust", just ordinary mineral dusts (clays, silt, etc) as a bulk filler in plastics, yet instead of ending up with a weaker product than working with pure plastic, you'd end up with a stronger one.

Maybe you don't even need a plastic. Maybe you can do what they're doing and bridge cellulose to an inorganic material? Then you're *really* operating on waste. Ice has the advantage of a low melting point in this situation, letting you use that component as a fluid - but cellulose can be dissolved in a number of substances, so perhaps you mix a cellulose-protein slurry with metal or mineral powders and then vaporize/recover the solvent?

Or even forgetting "novel" products, what about conventional composites? If you can bridge high-tensile fibres (such as carbon fibre) better to the polymer matrix that they're in, then you can help eliminate one of the main failure mechanisms of said composites, as well as making the behavior far more predictable. Because like metals (and unlike ceramics), a protein-bridged compound shouldn't be brittle; breaking one bond shouldn't introduce a discontinuity (like a ceramic), it should just reconnect after breakage (like a metal). Such composites should have ductility.

I don't know how widely applicable this will be, but technology that helps bridge dissimilar compounds is nothing to scoff at. And today we have tools like AlphaFold to assist with the design

As for the caveats:

* The concept of coupling agents is also not new, we already use various coupling agents to bond plastic to metal particles in metal-plastic composites and the like - they're just not great at their jobs.

* The aforementioned temperature limits

* Potential production challenges (though industrial enzymes are as cheap as like $15-50/kg, so seems viable?)

* Other coupling agents may offer better advantages; it's not a static field.

It's this.

And on the compression side, there's a lot of really cool stuff that lets it happen. For example, it dynamically resizes the blocks from 2x2 to 256x256, and they don't even have to be square. It may apply DCT in one, AFAS in another, etc - whatever is most efficient. It uses edge preserving filters to keep the edges of features clean. It can draw in splines and clone regions from one part of an image to another. Where it has to throw away high frequency noise (film grain, noisy textures, etc), it statistically samples the properties of the noise and saves that, and then regenerates equivalent noise. In "busy" areas, like say tree bark or whatnot (where the human eye isn't good at discerning changes), it throws away more precision there, and instead allocates it to details located in fragile flat areas, such as skin and shadows, that the eye is attracted to. It works in default in XYB colour space, based on the actual interactions of the cones in the eye, so it can aggressively quantize things which the brain cannot detect. And in the choice between fast but not-great Huffman coding vs. better but slow and patent-encumbered arithmetic coding, they instead use rANS, which is nearly as fast as Huffman but as efficient as arithmetic coding, and faces no patent challenges. Which is also why you can take a legacy JPEG and rapidly losslessly reincode as JPEG-XL and get a file that's ~20% smaller - you're swapping Huffman for rANS.

(That's the lossy mode - there's also a dedicated lossless mode)

Academy was a great Trek show. It captured the spirit of Star Trek and showed us how Starfleet helps young people develop into officers, while also giving us some new and interesting ideas. The characters were interesting, the legacy stuff wasn't obnoxious and actually added to what came before (especially for The Doctor after what B'Lanna did to him), and the overall writing and presentation overall was good.

Sorry Ami, but I'm gonna have to give a bit of a counter here.

Starfleet Academy was referenced in TNG and DS9 as a prestigious institution, only accepting the best. Wesley Crusher and Nog were both shown as really needing to be at the top of their game in order to be accepted into the academy. In Academy...pretty much everything was "find yourself and who you feel you really are, and the team will work around that".

Meanwhile, the setup for the story was that Holly Hunter left Starfleet because she was upset about a particular mother and son (Caleb) she separated when she was a judge, so she left, and now Starfleet needs Her In Particular to be a professor at Starfleet Academy (really, a whole universe full of people and we need one person who wasn't a teacher and resigned?), and she goes to find Caleb In Particular to join Starfleet because he's good at everything, in exchange for helping him find his mother...except that the "find my mother" plot thread is barely there, and not even Caleb seems to care for most of the season.

As the show gets going, Starfleet Academy (the institution) takes place on a ship that can just land and be a building, depending on what's necessary...and they go on a bunch of super dangerous missions that really require seasoned officers to do, but they have a bunch of cadets doing stuff they clearly shouldn't be doing...for, some reason. And they go out in space to do it instead of doing it all on the holodeck where it's far safer for...some reason. And, somehow, they're almost never in class in this college, except for one episode where we watch them be in debate class. Okay, fine, but...no engineering classes? No tactical training? No indication that they're actually learning to do the things we've seen Starfleet officers doing in the field?

Most of the show centered around the interpersonal drama, and I'll even grant some leniency here because it was pitched as having a "Dawson's Creek / Harry Potter" sort of coming-of-age focus. uhm...okay, fine...but quite a number of episodes had so much of that sort of focus, that it barely needed to be "Star Trek" to do it. They brought in the 'war college' to create some allusion to the Harry Potter houses, but do we spend a meaningful amount of time with sympathetic characters in The War College? No, we don't. Do we have any meaningful thought put behind the possibility that perhaps there's a need for a military-focused part of Starfleet in a universe that has physics-defying pirates (the last episode requiring an impossible feat of travel and resource acquisition), the way that Enterprise had the MACO's or the Elite Force games had the Hazard Team? ...no, they should join Starfleet Academy instead, where we learn nothing because Caleb already knows everything, everywhere, ever! And SAM only needed to realize that she's wonderful and perfect and had nothing to learn at all, so of course she's a perfect candidate for an institution of higher learning!

Finally, at least for my personal opinion, I found absolutely every single character insufferable for one reason or another. Holly Hunter is a captain-slash-professor who tells her leadership to get bent, and is shocked when the cadets have authority issues? I forget her name, but the Jem Hadar lady was generally annoying and useless, and somehow I got the feeling that half the cadets could have taken her in hand-to-hand combat. Caleb was "the key to everything", Genesis was every popular girl trope simultaneously, Ja'den was the living embodiment of 'not-Klingon'. The writers were clearly going for 'child-like' with SAM, but ended up at 'child-ish' instead. Tig Notaro was Tig Notaro playing Tig Notaro. You get the point.

Please note that I got through my whole list of exceptions without complaining one bit about "wokeness" or "politics in Star Trek" or anything related to it.

Anthropic is more or less breakeven *despite* being engaged in a massive 10x YoY scaleup for approaching 4 years running. Companies undergoing even "normal" scaleup rates are almost never profitable, let alone 10x/yr. Any slowdown in scaleup, or any shift in market pressures from intense jockeying for position to starting to pay back investors, and this drives them into deep profitability

The threat to Anthropic has nothing to do with whether its current business is sustainable or deeply profitable at its core. It is. Its threat is one I've been highlighting for years and now we're really starting to see: once something is "good enough", people start to question why they should be paying more for better. We now have the rise of a bunch of crazy cheap, yet quite coding-competent models like GLM 5.3 Flash, Qwen 3 Flash, MiMo 2.6 Pro, MiMo 2.6 Flash, Muse Spark 1.3 Contributor, etc. The latter two are almost too cheap to meter. Now, you still need an orchestrator, for planning, supervision, management, etc; it can either be a human or a higher-end model. But you don't need to pay for, say, Opus to get good coding done these days. Anthropic, like OpenAI, is built on charging a sizable premium over inference costs because they have the best and people will pay for it. And sure, in non-verifiable fields (say, medicine), maybe people keep paying for the best, whatever it may happen to be. But the more of the "bulk" coding and the like moves off these premium models and into dirt-cheap models, that seems to represent a real threat to their business model.

Anthropic's response thusfar seems to be "join them". Claude 5.5 Haiku is a good model "flash" model, and they've set quite affordable pricing for it, definitely fitting into the above category. But that doesn't really solve the problem. Their best hope is that Jevon's Paradox kicks up: that now that big projects are so cheap to implement, people keep taking on even bigger projects, scaling their income from cheap flash models like Haiku, orchestrators like Sonnet and Opus, and non-verifiable tasks where people will generally always want to pay for the best. But will that compensate? Hard to tell. This is the threat to Anthropic.

Unrelated aside, but back in the day when there was just vi, there was always a debate as to whether it's pronounced "vee" or "vie". Eventually my friends and I agreed on a way to settle the debate: we'd have a text-to-speech program read it out for us, and treat whatever it said as canon.

Maybe the real end of the world, if Trump reacts badly enough.

He's already scheming with his election deniers he's installed to thwart the midterm election by seizing ballots.

Peter Ticktin, Peter's attorney, said that she proposed that Trump seize ballots from across the country and conduct a hand recount, reports Kyle Clark of Colorado's 9 News.

"It's a good plan, and I do think that something like that is probably going to happen," Ticktin said to right-wing podcaster Joe Oltmann in Colorado. "In the event that we have this kind of disaster, and everything goes wrong, and the vote is crazy, and the senatorial races put it up there to remove the president and the vice president, in that nightmare, should it come true, Donald Trump is not going to relinquish control again."

And by disaster, they mean a blue wave sweeping across the country and driving out Republicans.
