autotldr Bot , in Stability announces Stable Diffusion 3, a next-gen AI image generator

This is the best summary I could come up with:


Stability says that its Stable Diffusion 3 family of models (which takes text descriptions called "prompts" and turns them into matching images) range in size from 800 million to 8 billion parameters.

The size range accommodates allowing different versions of the model to run locally on a variety of devices—from smartphones to servers.

Stability has made a name for itself as providing a more open alternative to proprietary image-synthesis models like OpenAI's DALL-E 3, though not without controversy due to the use of copyrighted training data, bias, and the potential for abuse.

We do not have access to Stable Diffusion 3 (SD3), but from samples we found posted on Stability's website and associated social media accounts, the generations appear roughly comparable to other state-of-the-art image-synthesis models at the moment, including the aforementioned DALL-E 3, Adobe Firefly, Imagine with Meta AI, Midjourney, and Google Imagen.

While Stable Diffusion 3 isn't widely available, Stability says that once testing is complete, its weights will be free to download and run locally.

"This preview phase, as with previous models," Stability writes, "is crucial for gathering insights to improve its performance and safety ahead of an open release."

huginn , in China invents most powerful detonation engine for hypersonic flight

This article is bullshit: they're reporting that a blueprint was made. No demonstration, no proof of it working.

Rotary detonation isn't a new concept and GE has demonstrated a rotary detonation scramjet for 0 - Mach 5.

https://www.geaerospace.com/press-release/other-news-information/ge-aerospace-demonstrates-hypersonic-dual-mode-ramjet-rotating

If you really think that 0 to Mach 16 is within reach with current technology RDEs I have a bridge to sell you.

Darpa has all the money of God and they've been throwing billions at the exact problem of rotary detonation. Everybody knows that detonation is more fuel efficient than deflagration and that turbine engines are holding jet aircraft back from hypersonic flight.

When they make a Mach 16 demonstrator I'll believe them. Until then I'm still very excited for the demonstrated and actual capabilities of RDE Scramjets.

pastermil , in China invents most powerful detonation engine for hypersonic flight

That's nice...

...when I see it in production.

Norgur , in China invents most powerful detonation engine for hypersonic flight

Yeah, no. Just no. Absolutely no. Faster than everything else.and higher than everything else and all of that by burning less energy? Come on people, stop falling for this kind of crap.

Rosco , (edited ) in China invents most powerful detonation engine for hypersonic flight

I'll wait until other countries validate the findings, or until someone makes a working prototype, before getting excited. Seems like it's one of those "too good to be true" stories like the LK-99. Hype in tech and science almost always leads to disappointment.

cmnybo , in China invents most powerful detonation engine for hypersonic flight

If that engine actually works, it would be cool to see it on a space plane. Mach 16 is nearly 2/3rds of orbital velocity. If you could go that fast on an air breathing engine, you wouldn't need to carry nearly as much oxygen to get into LEO.

Fuck the CCP with a bucket of rusty nails.

You need to draw the line between a country's government and some of its brightest minds. This is a scientific breakthrough, and should be celebrated as such. Period.

Tristaniopsis ,

No. Sorry, but if the government is horrific then any scientific advancements will be used in unethical ways. It’s unfortunate but true.

The CCP is brutally evil and that’s that.

viking ,
@viking@infosec.pub avatar

The research has been published. Everybody in the world is free to replicate it. The CCP is no more or less capable of doing so, just because it happened on their turf.

Kbin_space_program ,

It has been published, but a staggering number of scientific "papers" coming out of China are turning out to be complete fabrications.

viking ,
@viking@infosec.pub avatar

Correct, so it should be independently reviewed and recreated to validate the claims. Crying wolf just because there were issues before wouldn't be fair.

NoIWontPickaName ,

So you don’t base any of your decisions on past experiences?

viking ,
@viking@infosec.pub avatar

Not when it comes to scientific research.

If the same person or someone acting under the same supervisor in the same faculty published some more amazing sounding research after previous ones had been debunked, I'd be sceptical.

But in a country with 1.4bn people and more than 3.000 universities? There's gotta be some bad eggs, but you can't discredit every single one due to the actions of a few.

I've met brilliant scientists in and from China.

Kbin_space_program ,

The trick is that they're literally spamming papers at this point.

Zerush OP ,
@Zerush@lemmy.ml avatar

Most of these inventions will be used by military first, in China as also in the USA, which isn't an atom better in this and other aspect. It's precisely the USA which use more investment in weapons and defense as any other country and not precisely for humanity reasons.

Tristaniopsis ,

The US is committed to free speech, the CCP is not.

Are we? The current wave of book bans would say different.

It must be those two gay penguins’ fault

That's a different story, but you can simply look up the research paper.

If a space suit is needed, would the hat go inside or outside the suit?

@tsonfeir@lemm.ee avatar

I imagine you would need a cowboy hat that would also supply oxygen.

gaael ,

Outside, why wear a hat if no one can see it ?

That's why cowboy hats have folded brims.

The fact they killed Omegle over pretty much exactly this but it's apparently fine when Snapchat does it makes me angry. The only difference is one of them has billionaire investors to please.

BaumGeist , in Clinical trials show gold nanocrystals resulted in functional improvements for patients with multiple sclerosis and Parkinson’s

Here's the journal article itself

This whole thing stinks of advertising. They use a sample size of 24 people. The results are underwhelming: "Each disease cohort concordantly demonstrated increases in the NAD+/NADH ratio but did not reach significance individually" ("when we massaged the numbers, the result we wanted popped out"). Looking at the graphs, it looks like the upper half (highest baselines) of the patients worsened over the 12 week study.

My favorite lines?

"The objective of the Phase 2 REPAIR-MS and REPAIR-PD clinical trials was to investigate the effects of CNM-Au8" and "CNM-Au8® is a suspension of faceted, clean-surfaced gold nanocrystals" and course:

"Clene Nanomedicine, Inc., funded this study."

BaumGeist , in Clinical trials show gold nanocrystals resulted in functional improvements for patients with multiple sclerosis and Parkinson’s

So we've extracted so much gold from the earth there's not enough left for our bodies?

I know this probably isn't the case, but the image of extracting precious metals from human tissue solely to squeeze every last drop out of nature is hilarious to me. Plausible, but hilarious nonetheless. Mine owners leaving toxic lakes in the middle of Parkinson's patients when the earth runs out of gold.

GluWu , in Clinical trials show gold nanocrystals resulted in functional improvements for patients with multiple sclerosis and Parkinson’s

Is the crystal structure pertinent to the treatment or can they just be nanoparticles?

BaumGeist ,

None of the above. This study is as fishy as they come

CitizenKong , in Clinical trials show gold nanocrystals resulted in functional improvements for patients with multiple sclerosis and Parkinson’s

Reminds me of that South Park episode.

"Hey, poor people, we have the cure for Parkinson's, it's gold! Hurray!"
