When they weave their webs, spiders pull their silk threads. New simulations show stretching during spinning causes the protein chains within the fibers to align and the number of hydrogen bonds between those chains to increase. Both factors increase the silk fibers’ overall strength and toughness. Insights could be applied to designing stronger, tougher synthetic materials.

Energy remains a significant factor in industrial production processes. High levels of energy consumption make production more expensive and exacerbate the climate crisis. A new type of robot technology needs 90% less electricity than conventional systems. The technology uses lightweight, shape memory materials to construct novel, non-pneumatic, industrial gripper systems that function without the need for additional sensors.

Researchers have created washable and durable magnetic field sensing electronic textiles — thought to be the first of their kind — which they say paves the way to transform use in clothing. This technology will allow users to interact with everyday textiles or specialized clothing by simply pointing their finger above a sensor.
