Chinese researchers have developed a new carbon nanotube insulator that can withstand high temperatures up to 2,600°C, outperforming all other materials used for extreme-temperature applications. This breakthrough could be used for heat shields on hypersonic vehicles and spacecraft during re-entry into the atmosphere and in other high-temperature environments. /news/2025-09-breakthrough-carbon-nanotube-material-thermal.html Nanomaterials Sat, 06 Sep 2025 08:30:01 EDT news676297062 The movement of genetic material between organisms that aren't directly related is a significant driver of evolution, especially among single-celled organisms like bacteria and archaea. A team led by researchers at Bigelow Laboratory for Ocean Sciences have now estimated that an average cell line acquires and retains roughly 13% of its genes every million years via this process of lateral gene transfer. That equates to about 250 genes swapped per liter of seawater every day. /news/2025-09-quantify-essential-evolutionary-ocean.html Evolution Molecular & Computational biology Sat, 06 Sep 2025 06:20:01 EDT news676358182 Chemists at the University of Copenhagen have developed a method to convert plastic waste into a climate solution for efficient and sustainable CO2 capture.
