Recycled fertilizers from sanitation systems are as effective as conventional fertilizers, study finds
Agriculture depends on a reliable supply of nutrients. Phosphorus, nitrogen and potassium, for example, are indispensable for agricultural crop production. However, natural reserves are limited, vary greatly in regional availability or are very energy-intensive to extract.

Structure in the unstructured: New phenomenon discovered in the solar wind
Turbulence is ubiquitous and occurs every day, such as when milk is stirred into coffee or in the stormy motions of the ocean and the atmosphere. Media in space and astrophysical systems can also develop turbulence, but the physics is different because the medium is in an ionized

Copper-resistant bacteria complicate efforts to keep ship hulls clean
Marine bacteria have evolved to bypass the copper-based coatings applied to ship hulls to stop the growth of barnacles, algae and other marine life. This necessitates new methods for managing biofouling—the unwanted accumulation of marine organisms—on ship hulls.

Webb spots possible early-universe supernova just days after it happened
The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-forming galaxy at a redshift of 5.017 and was found without the help of gravitational lensing. JWST ob
