This rare earth metal shows us the future of our planet’s resources
For nearly as long as we’ve extracted materials from our planet, we’ve been trying to predict how long they will be able to meet our demand. How much can we pump from a well, or wrest from a mine, before we need to reconsider what we’re building and how?
We’re in the middle of a potentially transformative moment. Metals discovered barely a century ago now underpin the technologies we’re relying on for cleaner energy, and not having enough of them could slow progress.
Take neodymium, one of the rare earth metals. It’s used in cryogenic coolers to reach ultra-low temperatures needed for devices like superconductors and in high-powered magnets that power everything from smartphones to wind turbines. And very soon, demand for it could outstrip supply. What happens then? And what does it reveal about issues across wider supply chains? Read our story to find out.

Quote of the day
“If we take our clothes off when in our communities, then it has to be shown in the same way on the internet.”

The big story
The messy quest to replace drugs with electricity
May 2024
In the early 2010s, electricity seemed poised for a hostile takeover of your doctor’s office. Research into how the nervous system—the highway that carries electrical messages between the brain and the body— controls the immune response was gaining traction.
And that had opened the door to the possibility of hacking into the body’s circuitry and thereby controlling a host of chronic diseases, as if the immune system were as reprogrammable as a computer.
To do that you’d need a new class of implant: an “electroceutical.” These devices would replace drugs. No more messy side effects. And no more guessing whether a drug would work differently for you and someone else. In the 10 years or so since, around a billion dollars has accreted around the effort. Despite that, electroceuticals have still not taken off as hoped. But could that be about to change? Read our story.
