Possible reason for carcinogenicity of silica dust is found

Scientists have found unusual properties of silicon nanoparticles. They have shown that at normal conditions silica nanoparticles are enriched in oxygen. Such nanoparticles are magnetic and contain reactive oxygen species. This may explain the known high toxicity and carcinogenicity of silica dust.

New 'bottlebrush' electroactive polymers make dielectric elastomers increasingly viable for use in devices

A multi-institutional research team has developed a new electroactive polymer material that can change shape and size when exposed to a relatively small electric field. The advance overcomes two longstanding challenges regarding the use of electroactive polymers to develop new devices, opening the door to a suite of applications ranging from microrobotics to designer haptic, optic, microfluidic and wearable technologies.
