Citizen scientists have helped researchers uncover how parental care evolved in harvestmen, a group of spider like arachnids, by contributing observations through the popular nature platform iNaturalist. The findings, published in the Zoological Journal of the Linnean Society, reveal that parental guarding behavior has appeared, disappeared, and evolved again multiple times over the group’s evolutionary…
For the first time, astronomers have detected an atmosphere around a rocky planet orbiting in the habitable zone of a nearby star. Such planets have long been considered the best places in the galaxy to look for signs of alien life. But so far, “the planets looked like bare rocks,” says astronomer Laura Kreidberg of…
The emergence of agentic AI has created a paradigm shift in machine learning and artificial intelligence. In the past, we thought of generative AI as a resource that can provide information and predict outcomes, often used in tasks that harness pattern recognition, like various types of data analysis. But agents are now becoming more like…
China’s Tianwen-1 spacecraft has photographed the interstellar object 3I/ATLAS as it passed near Mars. According to the China National Space Agency (CNSA), the orbiter used its high-resolution camera to capture the comet from about 30 million km (18.6 million mi) away. Tianwen-1 has been orbiting Mars for four years and eight months, making it one…
Is a good live-action remake of an anime possible? On the Hollywood side of things, the track record is pretty spotty. For every Speed Racer (which, to be fair, was also derided in its time), there’s Dragonball Evolution. Or Ghost in the Shell. Okay, it’s a pretty bad track record, at least compared to the…
