Materials

Synthetic spider silk stronger and tougher than the real thing

Spider silk is one of nature’s most impressive materials, exhibiting impressive strength and toughness. Now, researchers at Washington University in St. Louis claim to have created an artificial version that can outperform some natural spider silks.

Energy

Anode-free sodium battery could cut cost and size from everyday devices

A new design out of Washington University in St Louis demonstrates a promising path forward for sodium batteries, with the team producing a device that is smaller and less expensive than lithium batteries, without compromising on performance.

Spun up with larger proteins, a new biosynthetic spider silk has been found to match the natural stuff in several key metrics

Materials

Bacteria build stronger biosynthetic spider silk, protein by protein

Strong as steel and tougher than Kevlar, spider silk is one of nature’s most impressive materials. Researchers from Washington University in St. Louis have now engineered bacteria to produce biosynthetic spider silk that they say performs as well as the real stuff.
