NASA's Perseverance robotic rover has detected complex organic carbon molecules hidden just under the surface of ancient rocks on Mars.
This finding, combined with comparable discoveries made thousands of miles away, indicates that essential chemical components for life could have been broadly distributed throughout the planet's past.
Additional information is anticipated as researchers continue to analyze the data and the story progresses.
Johns Hopkins scientists have uncovered hidden warning signs of Alzheimer’s disease that may appear up to a decade before memory loss begins. Brain scans revealed that two regions involved in memory and emotion start shrinking before the hippocampus, the area doctors typically examine for signs of Alzheimer’s. These early changes are linked to abnormal tau protein buildup and could provide a powerful new way to identify people at risk.
A groundbreaking drone survey has revealed a startling split in the fate of New Zealand's endangered Erect-crested penguins. While one population has remained stable for decades, another has declined by more than 40%, apparently due to a combination of predators, worsening storms, and changing ocean conditions. Even more surprisingly, the tiny Bounty Islands support nearly as many breeding pairs as the Antipodes Islands, despite being 40 times smaller.
Dinosaurs may have been snacking on seaweed and other ocean foods more than 100 million years ago, according to surprising new evidence hidden in their fossilized teeth. Researchers discovered chemical signatures suggesting that coastal dinosaurs and other prehistoric animals relied partly on nutrients originating in the sea. The findings reveal that marine resources traveled through ancient food chains, supplementing the diets of everything from plant-eating dinosaurs to predators.
Scientists have discovered how to use flashes of laser light to organize tiny electrical regions inside a crystal, solving a decades-old mystery about how the material behaves. The laser-induced alignment lasts just a trillionth of a second, but the breakthrough could open the door to new ways of processing and storing information.
ESA’s Euclid space telescope has discovered 31 ancient quasars, including two record-breaking objects that shone with the brightness of a trillion Suns when the Universe was just 670 million years old. Powered by supermassive black holes, these extraordinary cosmic beacons reveal a time when the first galaxies were still taking shape.
SpaceX has performed the historic catch using mechanical arms nicknamed "chopsticks".
