Solar eclipses send “gravity waves” through Earth’s atmosphere

Solar eclipses don’t just look cool – they can send gravity waves rippling through Earth’s atmosphere like dropping a stone in a pond. An international team of students has measured these gravity waves for the first time.

World-first nuclear clock prototype could outperform atomic clocks

Atomic clocks are our most accurate timekeepers, losing only seconds across billions of years. But nuclear clocks could steal their thunder, speeding up GPS and the internet. Now, scientists have built and tested the first prototype nuclear clock.

‘Nanowarming’ process a game-changer for organ transplantation

A new two-step process that safely rewarms frozen tissues using nanoscale magnetic rods could preserve donor organs long-term. The procedure provides an alternative to current time-limited methods and paves the way for more life-saving transplantations.

Giant gold nuggets could be born from earthquakes and electricity

Stumbling on a giant gold nugget and never working again is something we’ve all daydreamed about, but how exactly do they form? A new experiment has found that earthquakes and electricity might be key ingredients.

NASA discovers a new global energy field around Earth

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles and joins the known gravity and electromagnetic fields.

Watch Starliner return home empty on Friday – but it may have gremlins

The "not stranded" astronauts on the International Space Station (ISS) won't have an emergency ride home after Friday. NASA says that the uncrewed Starliner capsule will undock and return to Earth autonomously. Oh, and it might be 'haunted.'

Bio-based resin may find use in recyclable wind turbine blades

Although wind turbines generate electricity via an eco-friendly process, their blades end up in landfills once they wear out. That could change, however, thanks to a resin that would allow old blades to be broken down and recycled into new ones.
