Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs. The key innovation is an electrolyzer that automatically adapts to changing sunlight by ...

Scientists discovered that rice behaves in a highly unusual way: it weakens under rapid compression but stays stronger when pressure is applied slowly. Using this effect, they engineered a new material that reacts differently to gentle movements and ...

NASA has selected the Artemis III crew for a high-stakes 2027 mission designed to test the future of lunar exploration. Astronauts will launch aboard Orion and perform unprecedented docking operations with lunar landers being developed by both Blue . ...

JWST has revealed dramatic differences between the dawn and dusk regions of the scorching exoplanet WASP-121 b. Fierce winds appear to carry heat from the planet's permanent dayside, making the evening side hotter and more expanded. Scientists also . ...

Scientists found that transfer learning can make the search for new physics in the universe much faster, slashing the need for expensive simulations. Yet the approach can backfire when AI relies too heavily on familiar patterns, potentially missing . ...

MIT researchers have shown that one fuel can power both chemical and electric spacecraft thrusters, potentially transforming what small satellites can do. The approach combines quick bursts of speed with highly efficient long-range propulsion in a .. ...

Researchers gave top AI models a classic attention test used in psychology and found a major flaw. While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex. Some .. ...

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better able to retain their energy while traveling through . ...

Astronomers have spent years searching for a possible hidden giant planet far beyond Neptune. Unusual orbits among distant Kuiper Belt objects have fueled the Planet Nine theory, but recent discoveries are challenging the idea by showing more stable ...

NASA says a long-running air leak aboard the ISS recently worsened, leading engineers to investigate new suspected crack locations and consider a riskier repair strategy. Astronauts were temporarily moved into a safe haven as a precaution before the ...
