Today, China controls the vast majority of rare earths processing. That gives it enormous political leverage, and its trade truce with the US involving those minerals expires Nov. 10, 2026.

Robotic tools are too big for ‘keyhole’ brain surgery – but a new miniature technology using magnets could change all that.
With the fourth significant shortage of helium in a decade continuing, companies and researchers are looking for alternative sources.
Ever seen the northern lights? You have a magnetic layer in Earth’s atmosphere to thank for those beautiful displays. But the magnetosphere does a lot more than create auroras.
Room-temperature superconductors could transform technology – but the latest, much-hyped claims should be approached with caution.
Some birds may effectively possess an in-built, global GPS system.
Manipulating electron spin has heralded everything from iPods to the latest laptops. Stand by for the next paradigm shift.
Even fridge magnets have magnetic fields approximately 200 times stronger than Earth’s.
Your brain’s sensory talents go way beyond those traditional five senses. A team of geoscientists and neurobiologists explored how the human brain monitors and responds to magnetic fields.
The energy needed to pull magnets apart comes from you, and you get it from the food you eat. And the plants or animals you eat get their energy from other plants and animals, or from the Sun. All energy comes from somewhere.
These single-celled organisms naturally respond to the Earth’s weak magnetic field. Scientists are untangling how it all works, looking to future biomedical and other engineering applications.
