1. New catalyst turns carbon dioxide into clean fuel source

   Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far longer than similar low-cost materials. Surprisingly, the improved manganese catalyst even beat many expensive precious-metal options. The discovery could help turn greenhouse gas into clean energy ingredients.

2. Scientists just mapped the hidden structure holding the Universe together

   Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations from NASA’s James Webb Space Telescope, the research shows how dark matter gathered ordinary matter into dense regions, setting the stage for galaxies like the Milky Way and eventually planets like Earth.

3. This brain discovery is forcing scientists to rethink how memory works

   A new brain imaging study reveals that remembering facts and recalling life events activate nearly identical brain networks. Researchers expected clear differences but instead found strong overlap across memory types. The finding challenges decades of memory research. It may also help scientists better understand conditions like Alzheimer’s and dementia.

4. Even remote Pacific fish are full of microplastics

   Even in some of the most isolated corners of the Pacific, plastic pollution has quietly worked its way into the food web. A large analysis of fish caught around Fiji, Tonga, Tuvalu, and Vanuatu found that roughly one in three contained microplastics, with Fiji standing out for especially high contamination. Reef and bottom-dwelling fish were most affected, linking exposure to where fish live and how they feed.

5. Robots descend into lava tubes to prepare for future Moon bases

   Hidden lava tunnels on the Moon and Mars could one day shelter human explorers, offering natural protection from radiation and space debris. A European research team has unveiled a bold new mission concept that uses three different robots working together to explore these extreme underground environments autonomously. Recently tested in the volcanic caves of Lanzarote, the system maps cave entrances, deploys sensors, lowers a scout rover, and creates detailed 3D maps of the interior.
