A study in the Proceedings of the National Academy of Sciences has found that trees in cities like New York and Philadelphia start pollen production earlier and finish later due to light pollution, potentially extending the allergy season by up to 130 days; the effect is linked to plants using day length cues for flowering and leaf-out.
A wave of studies and official warnings links extreme heat and climate risks to data-center reliability, energy use and insurance costs. Analysts say operators must rethink cooling, water use and site choices to secure power and service resilience.
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.
