Wind energy is a valuable tool for addressing the climate crisis, but wind turbines can be deadly for birds. A recent study found that a low-tech, relatively inexpensive fix can dramatically reduce bird collisions with turbines: A can of paint. When wind turbines rotate their massive white blades can become a transparent blur, making them difficult to discern for birds, a phenomenon known as a motion smear or motion blur. Breaking up that blur, by painting one blade a different color, can theoretically make the turbine more visible to birds so they can navigate around the deadly blades. Researchers recently reported results from a long-term experiment that did exactly that: Between 2020 and 2021, Acciona Energía, owner of El Ruedo wind farm in Cadiz, Spain, painted one of three rotor blades black on four of its turbines. Another 16 turbines had all white blades and served as controls. Every day, from 2012 to 2024 (before and after the turbines were painted), they looked for dead birds under all 20 wind turbines and recorded their data. The researchers found that annual bird fatality rates dropped by nearly 74% for the painted turbines compared to the controls. The Spanish study joins others that have found similar results. A study in Norway found a more than 70% drop in annual bird fatalities after turbines had one of their blades painted black, while a South African study found bird deaths decreased by 83% after painting one of the three blades red.

From the seafloor to turtle stomachs, scientists are finding plastic everywhere they look for it. Now, researchers in Japan have found plastic thermally adhered to coral rubble, an amalgamation they’ve termed “plasticoral,” according to a new study. The finding is raising concerns about potential ocean chemical leaching, habitat degradation and a new way for microplastics to enter the marine environment, they say. Ifenna Ilechukwu, first author of the study with the University of Ryukyus in Japan, and his colleagues found five pieces of “plasticoral” on three different beaches during a routine marine litter survey on Japan’s Okinawa Island in August 2024. “We did not set out to discover plasticoral,” Ilechukwu told Mongabay in an email.  Researchers have previously described plastiglomerates, melted plastic debris fused with rocks, wood or other natural materials. However, when the team found coral rubble with plastic not just stuck on the surface but permanently adhered to it, they knew they’d found something unusual. Plasticoral is a subset of plastiglomerates, however, “plasticorals represent something different,” Ilechukwu said. “The melted polymers literally liquidized and conformed to the intricate, porous skeleton of the coral rubble.” Researchers suspect the plastic was burned into the rubble by a beach fire, though further research is needed to confirm that, Ilechukwu said. Laboratory analysis found that four of the plastic samples were polyethylene, commonly used for single-use bottles. One sample was polypropylene, a more rigid plastic used in food containers and bottle caps. Both are among the most common types of plastic found…This article was originally published on Mongabay
