Rings of time: Unearthing climate secrets from ancient trees Deep in the swamps of the American Southeast stands a quiet giant: the bald cypress (Taxodium distichum). These majestic trees, with their knobby "knees" and towering trunks, are more than just swamp dwellers—they're some of the oldest living organisms in Eastern North America. Some have been around for more than 2,500 years, quietly thriving in nutrient-poor, flooded forests where most other trees would wither. /news/2025-06-unearthing-climate-secrets-ancient-trees.html Plants & Animals Ecology Mon, 09 Jun 2025 15:00:06 EDT news668676541 Âé¶¹ÒùÔºicists create 'the world's smallest violin' using nanotechnology Âé¶¹ÒùÔºicists at Loughborough University have used cutting-edge nanotechnology to create what they believe may be "the world's smallest violin," which is small enough to fit within the width of a human hair. /news/2025-06-physicists-world-smallest-violin-nanotechnology.html Nanophysics Nanomaterials Tue, 03 Jun 2025 11:26:29 EDT news668168779 High-entropy nanoribbons offer cost-effective solution for harsh environments An SMU-led research team has developed a more cost-effective, energy-efficient material called high-entropy oxide (HEO) nanoribbons that can resist heat, corrosion and other harsh conditions better than current materials. /news/2025-05-high-entropy-nanoribbons-effective-solution.html Nanomaterials Thu, 29 May 2025 16:39:04 EDT news667755541 Ballistic electrons chart a new course for next-gen terahertz devices In a world increasingly driven by high-speed communication and low-power electronics, a team of researchers from the National University of Singapore (NUS) and Singapore University of Technology and Design (SUTD) has proposed a fundamentally new way of manipulating light using the geometry of matter itself. /news/2025-05-ballistic-electrons-gen-terahertz-devices.html Nanophysics Nanomaterials Thu, 29 May 2025 10:15:03 EDT news667732501 Underground water channels preserve ancient climate records in their shape Water reshapes Earth through slow, powerful erosion, carving intricate landscapes like caves and pinnacles in soluble rocks such as limestone.
