The country has endured violent earthquakes, including the most powerful recorded in history: a 9.5-magnitude "megathrust" event that struck central Chile in 1960, causing a tsunami and killing between 1,000 to 6,000 people. However, the Calama quake was different from the megathrust quakes that are usually associated with the most destructive events in Chile and around the world. /news/2025-09-thermal-runaway-mechanism-ramp-magnitude.html Earth Sciences Tue, 30 Sep 2025 12:12:04 EDT news678453121 A team of researchers including Rice University's James Tour and Shichen Xu has developed an ultrafast, one-step method to recover rare earth elements (REEs) from discarded magnets using an innovative approach that offers significant environmental and economic benefits over traditional recycling methods. /news/2025-09-rapid-joule-technique-efficient-rare.html Analytical Chemistry Materials Science Tue, 30 Sep 2025 11:20:08 EDT news678449685 A quantum computer has demonstrated that it can solve a problem more efficiently than a conventional computer.

This process is known to prevent atherosclerosis, the build-up of plaque in the walls of arteries. Atherosclerosis is associated with deadly symptoms, including heart attacks, strokes, aneurysms, and blood clots.
