Illustration of double layer mesoporous carbon sphere catalyst with single atom dual sites. The inner Fe-N₄ centers drive nitrogen-nitrogen coupling, while the outer Mg-N₄ shell acts as a proton barrier, directing the reaction toward harmless nitrogen gas (N₂) instead of ammonia. This design achieves high nitrate removal and exceptional selectivity, offering a sustainable solution for…
Researchers at the University of California, San Diego School of Medicine, in collaboration with the genetic testing company 23andMe, have identified regions of the human genome related to cannabis use. Their discoveries reveal new genetic connections to psychiatric, cognitive and physical health, offering insights that could eventually guide prevention and treatment strategies for cannabis use…
The phenomenon of differential rotation in the Sun, described by equation 1 where A is the equatorial rotation speed, A and C are latitudinal gradients, and \theta$ is the latitude, is a cornerstone of solar dynamo theory. While helioseismology and feature tracking at optical and EUV wavelengths have helped map this profile at the surface…
NASA’s plans to fly a spacecraft past a potentially dangerous asteroid in 2029 will continue, at least for the next year. After threats of mission cancellation, the OSIRIS-APEX spacecraft received a last-minute allocation of $20 million in the House budget bill to continue basic operations during the next fiscal year. However, the fate of 18…

Scorpion venom as a source of anticancer drugs: a comprehensive proteomic analysis and therapeutic potential Abstract Scorpion venom is a rich source of bioactive compounds with significant potential for anticancer drug development. Its diverse molecular composition, including neurotoxins, antimicrobial peptides and enzymes, provides a broad library for therapeutic innovation. Proteomic analyzes have characterized venom composition…
Jane Goodall, the primatologist who forever changed our understanding of humanity’s closest relatives and became a tireless global advocate for the natural world, has died at the age of 91. She died of natural causes on October 1, 2025 in California, where she was still on a speaking tour, proof that her mission took her…
The early days of Earth were so chaotic that it’s hard to believe life began here. What is now the beautiful blue marble we inhabit was once an apocalyptic wasteland with a molten surface and an atmosphere severely lacking in oxygen. Virtually all evidence of this fiery first era of the planet, known as “proto-Earth,”…
The world’s first commercial deep space astronomical telescope is set to search for stars that may host habitable exoplanets in their orbits. The Mauve telescope, developed by London-based startup Blue Skies Space, is the size of a small suitcase and carries a commercially available ultraviolet spectrometer modified to monitor burning stars. It is one of…
