Japan has created a tiny hydro generator, small enough to fit in a matchbox, that harvests electricity from moisture and airflow in the air — no rivers, sunlight, or moving parts required.
The device works by capturing natural humidity and converting it into a constant stream of electrical energy. Unlike solar or wind, it doesn’t depend on weather or daylight, making it a 24/7 clean power source.
Potential uses range from powering small electronics and medical sensors to supplying energy in remote areas without access to the grid. Its portability means it could also play a role in disaster relief, where reliable power is critical.
If scaled up, this breakthrough could complement renewable energy systems worldwide, offering clean electricity literally “out of thin air.”

Scientists at the University of St Andrews have achieved a breakthrough that could bring true holograms to everyday devices. By combining OLED screens — the same technology already used in many smartphones and TVs — with engineered nanosurfaces called metasurfaces, they’ve shown it’s possible to project full holographic images without bulky lasers. Each “meta-atom” on the surface bends light in precise ways, so even a single OLED pixel can project a complete 3D image. This approach is simpler, cheaper, and smaller than traditional holographic setups, opening the door to practical applications in phones, gaming, augmented reality, and beyond. Researchers say it removes one of the biggest barriers keeping holograms out of consumer tech, bringing us a step closer to holographic displays you can hold in your hand.

🚨BREAKING: NASA’s new cargo ship to the ISS hit a big snag – but it has now safely arrived.

The Cygnus XL, a new spacecraft built by Northrop Grumman, launched from Cape Canaveral on September 14 carrying more than 11,000 pounds (5,000 kilograms) of food, equipment, and experiments for the station’s crew. That’s about one-third more cargo than its predecessor could handle, making it the biggest version of Cygnus yet.

But the journey hasn’t gone entirely to plan. On September 16, Cygnus XL’s main engine shut down earlier than expected during two planned orbit-raising burns. The shutdown wasn’t due to a failure, NASA later explained, but a conservative safeguard in the software that triggered an automatic stop. Engineers reviewed the data, built a new burn plan, and kept the spacecraft safely behind the station until it was ready to try again.

The plan worked. At 7:24 a.m. EDT on September 18, NASA astronaut Jonny Kim, with assistance from Zena Cardman, captured Cygnus XL using the station’s Canadarm2 robotic arm. The spacecraft will now be installed on the Unity module’s Earth-facing port.

The spacecraft will now be installed on the Unity module’s Earth-facing port, where it will remain until March 2026.

Uncrewed cargo ships like Cygnus are lifelines for the International Space Station 250 miles (402 kilometers) above Earth, carrying everything from meals to research gear. And while engine anomalies highlight the risks of spaceflight, the successful capture shows the resilience built into these missions.

This flight also marks a milestone: the debut of the Cygnus XL, the most capable version yet, able to haul 33% more cargo than before.
