Matter Discovered Traveling at Near Light Speed 403

mcgrew writes to mention New Scientist is reporting that scientists have clocked matter traveling at 99.999% the speed of light. "The fastest flows of matter in the universe shoot out of dying stars at more than 99.999% the speed of light, new observations reveal. When a massive star runs out of fuel, it collapses to form a black hole or a neutron star. In the process, some of the matter from the star also explodes outward at blistering speeds, producing an intense burst of gamma rays and other radiation."

Self-Healing Plastic Skin 104

Posted by kdawson
from the polymer-heal-thyself dept.
An anonymous reader writes "Scientists have developed a form of plastic skin that can heal itself when damaged. The material relies on an underlying network of vessels — similar to blood capillaries — that carry a healing agent to areas on the material's surface that sustain damage. Unlike previous self-healing systems that relied on capsules of agent buried in the polymer and which became depleted after one use, the new system can respond to damage at the same point many times over."
