Scientists have found macromolecular carbon in Martian mudstones, suggesting habitable conditions billions of years ago. The carbon could be biogenic or abiotic; samples will return to Earth for definitive testing, with timelines running 2035–2039. This marks multiple robust organic detections across Jezero crater and Gale crater.
A body of studies is showing that a blood marker called p-tau217 can forecast an elevated risk of cognitive impairment in healthy older adults years before symptoms appear.
