Korean scientists claim a major breakthrough


Korean scientists claim to have developed the world’s first superconductor capable of working at room temperature and pressure. If true, this is big.

What’s a superconductor? It’s a material capable of conducting electricity without resistance. We only know how to make them work at ultralow temperatures or ultrahigh-pressure, severely limiting their use. Until now?

Sukbae Lee and Ji-Hoon Kim have developed a material with lead, oxygen, sulphur, and phosphorus called LK-99 (for ‘Lee’, ‘Kim’ and ‘1999’ when they first made it). They’ve released their findings, claiming it’s a superconductor at room temperature and pressure, heralding “a new era for humankind”.

So scientists are racing to replicate their results: early tests in India and China have dashed hopes, while another in China has spurred them.

Why the excitement? If LK-99 is the real deal, it could revolutionise anything that uses electricity or magnets, including the:

  • ⚡ energy sector (sending more green energy over longer distances)
  • 🩺 medical sector (cheaper, more powerful devices)
  • 🚄 transport sector (cheaper, more practical maglev trains), and
  • 💻 tech sector (cheaper, more powerful quantum devices).

Intrigue’s take: But (always the but), big claims merit scrutiny, and there are real questions here around the original methods and rigour. Plus, there are other theories to explain LK-99’s properties (it could just be diamagnetic).

So there’s a fair bit of scepticism building.

But while we await further testing, we can’t help but reflect on the way major finds like this can really shape our world: oil, nuclear, space, chips, critical minerals, AI… ambient superconductors? This is a heck of a time to be alive.

Also worth noting:

  • The Korean Society of Superconductivity and Cryogenics has organised a committee to verify the LK-99 findings, which haven’t been peer-reviewed.
  • Stocks seen as having relevance to LK-99 initially surged in Korea and elsewhere, before tanking today (Friday) as LK-99 doubts grew.

Why the world is having fewer babies

Why are a bunch of ex-diplomats talking about babies and birth rates? Sure, it’s like a mango sorbet palate-cleanser amid all the war and rumours of war. But natality is also one of those slow-moving forces that can completely transform our world. How? Last century, the dominant narrative was that populations were too big, with leaders in China, Vietnam […]

Xi and Trump talk for the first time

Sometimes, the shortest press releases generate the most headlines.   Take Thursday’s press release from China’s state broadcaster: “Chinese President Xi Jinping on Thursday held phone talks with U.S. President Donald Trump at the latter’s request.”  As you’d expect, given the feverish geopolitical climate of today, those 18 words were enough to trigger a visceral reaction in any US-China […]
