Scientists Use Sound Waves to Remotely Switch Material Stiffness

A team led by UC San Diego has shown that sound waves can act like a remote control for a material’s stiffness by moving tiny internal features called kinks. The work hints at future protective gear, soft robots and implants that can adapt on demand.

Roadside ‘EyeDAR’ Sensors Give Self-Driving Cars New Vision

A new radar “tag” called EyeDAR could give self-driving cars an extra set of eyes by turning streetlights and stop signs into smart, talking sensors. Rice University engineers say the low-power devices may help autonomous vehicles see around corners, through bad weather and beyond their own blind spots.
