Scientists have cracked a long-standing chemistry problem, creating nanocrystals from tough metal nitrides that were previously extremely difficult to produce at this scale. The breakthrough could turn familiar materials used in LEDs, implants, and superconductors into building blocks for flexible electronics, printable devices, and other technologies.

Researchers have discovered that Western Australia’s iron-rich rocks can naturally generate hydrogen and that the process may be boosted to produce much larger amounts. If it can be scaled up, the vast formations beneath the Pilbara could become a major new source of low-emission energy for Australia and potentially the world.

NASA’s Roman Space Telescope will combine Hubble-like detail with a field of view 100 times larger, giving astronomers a sweeping new way to explore the cosmos. Its observations could uncover hidden planets, map billions of cosmic objects, and help scientists unravel the mysteries of dark matter and dark energy.

A magnetar with an astonishingly powerful magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago. Its light shows signs that supposedly empty space is altering how the light travels, potentially providing the first evidence of vacuum birefringence.

A single asteroid impact may explain two of Deimos’s most puzzling features: its huge southern depression and unusually smooth, dusty surface. Simulations suggest a roughly 320-meter asteroid struck the Martian moon at an angle, throwing debris around the entire world without breaking it apart. New observations from ESA’s Hera spacecraft support the scenario and indicate that Deimos is surprisingly porous and fragile.

A massive test of gravity across the cosmos found that it behaves almost exactly as Newton and Einstein predicted, even across galaxy clusters hundreds of millions of light-years apart. The result weakens some modified-gravity explanations and strengthens the case that dark matter is behind the universe’s mysterious missing mass.
