Researchers create a new test method that detects nanometer-scale holes, free radicals, and cross-linking in paints, allowing for early detection of damage and more efficient development of durable paints. This breakthrough could lead to cost-effective solutions for bridge coatings and other applications.
Physicists have achieved head-on collisions between electrons and positrons at the Asymmetric B Factory, a $177 million particle collider. The dual-ring machine will help researchers study the differences between matter and antimatter.
Researchers observed hundreds of thousands of high-energy collisions between protons and positrons, far exceeding expected statistical probabilities. The unexpected results may indicate new physics or a mistake in understanding what's inside the proton.
