Researchers at the University of Birmingham have developed a new low-temperature approach to hydrogen production that could make the clean fuel cheaper and more practical to generate. The technique could be used both in large centralized facilities and in smaller local systems that take advantage of waste heat from major industrial operations.

Scientists at Monash University have created a tiny new circuit that can generate, direct, and read information carried by light, all within a single chip.

The advance marks a significant milestone for a growing area of research known as "valleytronics," which could help drive future breakthroughs in faster computing, lower energy consumption, and quantum technologies.

But the leaders running real businesses are increasingly asking the right questions. How do I make my people better with AI? Which systems can I trust? How can I measure the ROI of this spend? We hear these questions every day.

NASA's X-59 quiet supersonic research aircraft is approaching one of the most important stages of its development. The experimental X-plane is set to begin a new series of test flights that will include its first trip beyond the speed of sound, along with several other key objectives for the mission.

A striking new image from the NASA/ESA Hubble Space Telescope highlights Messier 88 (M88), a spiral galaxy embarking on a journey that will unfold over hundreds of millions of years.
