NASA satellites have detected a vast pulse of warm water reaching the coast of South America, signaling that El Niño is likely developing. The warm water is being carried eastward by massive ocean waves known as Kelvin waves, which also cause sea levels to rise. El Niño can reshape weather...
Honey bees have their own personal flight paths and fly them with stunning precision
Researchers tracked honey bees in the wild using a drone-based system and found that each bee follows its own highly consistent flight path. Some repeated their routes so precisely that they flew only centimeters from where they had flown before. Landmarks like trees helped keep them on track, while uniform...
Beneath our feet lies a fungal superhighway stretching 68 quadrillion miles
Beneath our feet lies a vast hidden fungal superhighway that helps sustain much of life on Earth—and scientists have now mapped it for the first time. Researchers estimate that these underground networks stretch an astonishing 110 quadrillion kilometers, move about 4 billion tons of carbon dioxide into soils each year,...
Yellowstone wolves may not have reshaped the national park after all
One of the most celebrated claims about Yellowstone’s wolves is facing a major challenge. Scientists say the study behind the famous trophic cascade story relied on flawed methods that overstated the ecological impact of wolf recovery. Their reanalysis found no evidence for a dramatic, park-wide surge in willow growth. Instead,...
Scientists discover parrots may actually use names
Parrots may be doing more than just repeating words—they may actually use names. By analyzing hundreds of recordings from pet parrots, researchers found evidence that many birds use specific names to identify particular people, animals, and even individual companions. Some parrots appeared to refer to someone who wasn’t present, while...
Lucy’s hunter revealed: Giant crocodile terrorized early human ancestors
A newly identified crocodile species nicknamed “Lucy’s hunter” prowled Ethiopia’s rivers when Lucy’s species walked the Earth more than 3 million years ago. The giant predator was likely the most dangerous animal in the ecosystem and may have regularly hunted early human relatives.
A legendary golden fabric lost for 2,000 years has returned
Researchers in South Korea have recreated the legendary “sea silk” once prized by emperors, using fibers from a clam cultivated in Korean coastal waters. They discovered that its famous golden shine comes from tiny protein structures that reflect light rather than from pigments or dyes. Because the color is built...
The missing notebooks that solved a 55-million-year-old fossil mystery
A spectacular fossil fish discovered on a remote cliff in New Zealand nearly 30 years ago has finally revealed its full story thanks to an unexpected discovery: the original collector’s long-lost field notebooks. The 1.2-meter fossil, preserved in stunning three-dimensional detail, belonged to an ancient tarpon-like predator that cruised New...
Alaska’s glaciers have a startling response to rising temperatures
Alaska’s glaciers are proving to be highly sensitive to warming temperatures. Using radar satellites to monitor more than 3,000 glaciers, researchers found that every 1°C (1.8°F) increase in average summer temperature extends glacier melting by about three weeks. The study also revealed that intense heat waves can strip away up...
Toward Battery-Free Artificial Photosynthesis: Stable Fuel Production at Lower Cost
Redesigned electrolyzer generated enough power to run a diorama at Osaka Expo.
