Living organisms need nitrogen as a central building block for protein formation, for example. However, although our atmosphere contains plenty of nitrogen, neither humans nor the vast majority of plants can absorb it directly from the air.

The man crashed his car into a D.C. cruiser and threatened an officer through the window before being wounded; he then stabbed himself and threatened others before being fatally shot
Chiral-structural-color materials produce color through microscopic structures that interact with light rather than through pigmentation or dyes. Some beetle exoskeletons, avian feathers, butterfly wings, and marine organisms feature these structures naturally, producing iridescent or polarization-dependent colors. Over the last 10–15 years, scientists have made progress in developing artificial chiral-structural-color materials.
The man repeatedly struck a cruiser parked outside a sheriff’s department substation with a 16-inch machete before being confronted by a deputy
Many next-generation quantum devices rely on single-photon emitters based on optically active defects in solids, known as color centers. Understanding their properties is fundamental to developing novel quantum technologies.
Neutrinos have always been difficult to study because their small mass and neutral charge make them especially elusive. Scientists have made a lot of headway in the field and can now detect three flavors, or oscillation states, of neutrinos. Other flavors continue to be elusive—though that could be because they don’t even exist.
Saratoga Springs police and neighbors strained to pull a 1,300 pound horse named Sly from a hole in the icy pond
Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. A new study published in the journal Cell suggests that these issues could be due to the excessively sterile nature of spacecraft.
Using the James Webb Space Telescope (JWST), an international team of astronomers has explored the atmosphere of a nearby brown dwarf binary designated WISE J045853.90+643451.9. As a result, they detected hydrogen cyanide and acetylene in the atmosphere of this binary, marking the first time these two species have been identified in the atmosphere of a brown dwarf. The finding was reported Feb. 19 on the arXiv pre-print server.
The first metal 3D part ever created in orbit has landed on Earth.
At the start of the year, the European Commission established the Cherenkov Telescope Array Observatory (CTAO) as a European Research Infrastructure Consortium (ERIC), furthering its mission to become the world’s largest and most powerful observatory for gamma-ray astronomy.

For centuries, lenses have worked the same way: curved glass or plastic bending light to bring images into focus. But traditional lenses have a major drawback—the more powerful they need to be, the bulkier and heavier they become.
Neutron stars are some of the densest objects in the universe. They are the core of a collapsed megastar that went supernova, have a typical radius of 10 km—just slightly more than the altitude of Mt. Everest—and their density can be several times that of atomic nuclei.
Researchers at Tohoku University, the University of Manchester, and Osaka University have made a breakthrough that has the potential to ignite the development of next-gen chiral information technology.
