All cellular life—from humans to bacteria—possesses two layers of immunity: innate and adaptive. Scientists have long understood how these two types of immunity work together in higher organisms but not in the microbial world. https://phys.org/news/2026-07-crispr-cas-layered-bacterial-defense.html Cell & Microbiology Wed, 22 Jul 2026 15:40:06 EDT news703945801 Around 80 million years ago, a stretch of tropical coastline in what is now northeastern Italy was lashed by monsoon rains and tropical cyclones. Those storms swept dinosaur carcasses, crocodiles, plants and river mud onto a tidal flat, where the tides and a film of microbes sealed everything away with extraordinary preservation. https://phys.org/news/2026-07-storms-built-graveyard-ancient-monsoons.html Paleontology & Fossils Wed, 22 Jul 2026 13:20:09 EDT news703938783 An international research team led by scientists from the Max Planck Institute for Marine Microbiology in Bremen and the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) investigated how the shape of black corals influences the functions of their cilia.

But beneath the surface, these small, shallow waters are anything but stable. In fact, they are among the most thermally variable aquatic ecosystems on Earth, with water temperatures sometimes swinging more than 20°C (36°F) in a single day. According to new research published in the journal Ecosphere, the force driving much of that variability begins months earlier: winter snowfall. https://phys.org/news/2026-07-snowpack-sierra-nevada-mountain-ponds.html Environment Wed, 15 Jul 2026 14:00:32 EDT news703338781
