Spider silk conducts heat as well as metals

Researchers discovered that spider silks - particularly the draglines that anchor webs in place - conduct heat better than most materials, including very good conductors such as silicon, aluminum and pure iron. Spider silk also conducts heat 1,000 times better than woven silkworm silk and 800 times better than other organic tissues.

Battery 500 Project: 800 km range for electrovehicles

IBM's Battery 500 project, led by scientists at IBM Research - Almaden in California, is an interdisciplinary consortium to develop a lithium-air battery that aims to increase the range of electrovehicles to 500 miles (approximately 800 km). This is more than five times the range of today's batteries, which average some 150 km per charge.
