The researchers in China and Canada reporting the stronger materials with no side effects can be from human origin. Bile acid derived resins form hard, durable plastics that can prevent the cracking better than the current composites. - ACS

Regular Light Bulbs Made Super-Efficient with Ultra-Fast Laser

An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.
