AI Hunts the Material That Could Rewire the World

An international physics consortium is using machine learning to find room-temperature superconductors — and the search just got dramatically faster.

Picture a power cable that wastes absolutely nothing. No heat, no lost energy, no hum of resistance — just electricity flowing as if friction had been uninvented. That is what a superconductor does. The catch?

Every superconductor we know of needs to be cooled to temperatures close to absolute zero before the quantum magic begins. Now, a global research team thinks artificial intelligence can help crack the problem wide open. The SuperC consortium, founded in 2023 by Aalto University's Professor Päivi Törmä, is the first coordinated worldwide collaboration with a single, audacious target: discover a room-temperature superconductor by 2033. The team's latest results show that machine learning can sweep through an almost infinite landscape of chemical combinations and pinpoint the most promising candidates in a fraction of the time it would take any human researcher.

Two new materials — YRu3B2 and LuRu3B2 — have already been identified this way.

Discuss
  • Why might finding a room-temperature superconductor be considered one of the greatest scientific achievements ever?
  • Machine learning speeds up the search, but humans still interpret the results. Does that make AI a tool or a collaborator?
  • The kagome lattice comes from Japanese basket weaving. What does this suggest about where scientific inspiration can come from?
  • If data centres used zero-resistance conductors, how significant could the impact on global energy use realistically be?
  • Should a discovery as potentially world-changing as this be funded publicly, privately, or through international cooperation — and does it matter?

AI Reads Proteins Like a Book

A lizard's saliva helped create Ozempic. Now imagine what scientists could do if they could instantly decode billions of unknown proteins. That is exactly what BetaDescribe promises. Researchers at Technion and Tel Aviv University built an AI that reads raw protein sequences and produces plain-language descriptions of what those proteins actually do — their functions, binding sites, and metabolic roles. …
  • Should AI-generated protein descriptions be trusted in drug development without full lab testing?

Dirty Air May Rewrite Sperm DNA

In Salt Lake City, more than 2,000 men quietly handed over semen samples every two months. What researchers found inside those samples is unsettling. Scientists at the University of Massachusetts Amherst discovered that exposure to ozone and nitrogen dioxide appears to alter DNA methylation in sperm — chemical tags that switch genes on or off without rewriting the genetic code itself. …

2GRAMMAR FOCUS
Passive voice — full range (simple, continuous, perfect, modal passive)
The passive voice is formed with the correct tense of 'be' plus a past participle; it shifts focus onto the action or its result rather than who performs it, and modal passives use 'modal + be + past participle'.
