China's decision in April to suspend exports of a wide range of critical minerals and magnets has upended the supply chains central to automakers, aerospace manufacturers, semiconductor companies and military contractors around the world.

We were working on this several years ago.

In the Mojave Desert, the rebirth of the only American rare earth mine

With support from the US government, mine operator MP Materials is reviving the Mountain Pass site. The company is taking advantage of the global appetite for magnets for electric motors and wind turbines.

Those MP Materials guys also do processing.

Attempts to establish commercial-scale rare earth separation and processing outside China are growing in number and progressing gradually with a view to ramping up output over the next two years.

Mineral resources developers are scrambling to reassess and upgrade their estimates of mineable rare earth element (REE) content as western governments attempt to encourage producers to establish production closer to home. And new efforts to develop high-volume processing capacity outside China — which currently accounts for more than 80pc of global refining — are emerging.

Western countries are well behind China in advancing technical processes to refine REs from raw materials, as they seek alternatives to the highly polluting solvent extraction process. But with China banning the export of RE extraction and separation technologies in December 2023, as well as exports to the US of key electronic metals in December 2024, the impetus is growing to come up with viable Western production.

RE oxides are used in the manufacturing of permanent magnets for electric vehicle (EV) motors, wind turbines and electronics, as well as batteries, lasers, metal alloys, medical devices and military equipment.

Given that latter application, the US Department of Defense (DoD) has awarded more than $439mn in financing since 2020 to support a new domestic supply chain, from the separation and refining of materials mined in the US to downstream production of magnets. In a broader trend towards "friendshoring" of critical material supply, the DoD considers Canada, Australia and the UK as domestic suppliers.

Like the US, European countries are also targeting domestic production in a bid to secure their supply chains.

Projects include the expansion of Nd and NdPr processing capacity at UK-based Less Common Metals (LCM), the addition of NdPr production at Belgian chemical group Solvay at its plant in France in 2025 and French consultancy Carestar's plan to start production in 2026 of RE oxides from mining concentrates and, later, recycled magnets. REEtec in Norway plans to start a commercial NdPr plant in 2025 and Swedish state-owned LKAB plans to start an RE oxide demonstration plant by the end of 2026. These initiatives are in line with plans across Europe to increase EV manufacturing and renewable energy.

Rare earth mining projects in Africa and Australia are largely targeting supply deals or integrated production in Asia or North America. Miners in Brazil, such as Aclara, are also planning integrated production by developing separation plants close to demand in the US and Europe.

On an entirely-unrelated note, I would make the following observations:

and it’s especially surprising coming from two companies that serve billions of users worldwide

I mean, deanonymization and data-mining costs are gonna be R&D, so they're a fixed cost that doesn't really scale up with the size of the userbase, so it makes more sense, financially, for a company with a larger userbase to be putting resources into it.

You don't need to hit boiling levels to evaporate water.

You can editorialize in the body on Lemmy

Or, even better, just comment with one's position like everyone else.

Just noticed this on !technology@beehaw.org, which lemmy.world is defederated with. As I've seen a number of people using catbox.moe to host content posted on here before, thought it'd be of broader interest than to just the beehaw.org crowd.

It looks like CNN has video:

At least some of that has to be sped up to fit in the short clip, though.

EDIT: Ah, yeah, the bit I'm thinking of does mention that it's timelapse.

Europe consists of a bunch of peninsulas surrounded by ocean.

https://en.wikipedia.org/wiki/Baltic_Sea

Water volume: 21,700 km³ (1.76×1010 acre⋅ft)

https://en.wikipedia.org/wiki/Mediterranean_Ocean

Water volume: 3,750,000 km³ (900,000 cu mi)

https://en.wikipedia.org/wiki/Atlantic_Ocean

Water volume: 310,410,900 km³ (74,471,500 cu mi)

EDIT: For bonus points, if one is going to expend the waste heat on evaporating seawater anyway:

The North Korean government's totalitarianism predates Ninteen Eighty-Four. North Korea might have been an input for Nineteen Eighty-Four, mind...

As best I can tell from Trump administration statements, their strategy for mitigating their political damage has been to publicly demand that WalMart and other companies just take losses as he increases their input costs.

That's not going to happen, but I suppose that it doesn't matter, if enough people believe that it could.

I remember switching away from floppies to a--much faster, enormous---80MB hard drive. Never did come close to filling that thing.

Today, my CPU's cache is larger than that hard drive.

The plugin does, unless things have changed since it left GitHub, request permission on a by-website basis in Firefox. I kind of doubt that most people are reviewing that (large) list, but that's probably about as restrictive as one could reasonably do something like this.

The TLD of the source domain is probably more-or-less irrelevant as security. If someone were trying to set up malware, if they were willing to go through even the barest of efforts, they'd be more likely to do it through a VPN on a "legitimate-looking" domain; that's one of the lowest-effort ways to increase the credibility of malware. As I recall, Jia Tan did that on GitHub.

EDIT: Hmm. That does kind of suggest that Firefox might benefit from a plugin model where plugins could only have permission to process the "current page" when a button is clicked, which I'd guess would likely work for Bypass Paywalls Clean, even if it's not how it works today. Some plugins, like Behind The Overlay, could reasonably function in such a manner.
