A new look at color displays
Tunable structural color images by UV-patterned conducting polymer nanofilms on metal surfaces.
Pop-up furniture — no assembly required
Kiriform structures harness buckling for stable, deployable structures.
Rice-sized robots maneuvered with magnetic fields
Researchers create swimming, moving, gripping miniature robots.
3D printers with “eyes and a brain” to advance body implants
Machine vision and artificial intelligence can fine tune medical 3D printers to enable custom made tissue implants to suit the individual patient.
3D printing cell substrate topographies
Scientists use 3D printing to combine fundamental biology research methods with high-throughput screening of cell culture surface topographies.
Nanoengineered heartbeat via a semi-conductive hydrogel
A conductive biomaterial that supports the growth of cardiac muscle cells and facilitates their synchronous beating holds great potential for cardiac tissue engineering.
A powerful underwater glue inspired by barnacles and mussels
Using silk proteins, researchers create crosslinking fibers that contain iron complexes similar to those used by sticky underwater sea creatures.
The biodegradable battery
Researchers build a biodegradable mini-capacitor that consists of carbon, cellulose, glycerin, and table salt — and it works reliably.
A robot that smiles back
Researchers teach robots to make appropriate reactive human facial expressions, an ability that could build trust between humans and their robotic co-workers and care-givers.
