Keeping a tight hold on things: Robot-mounted vacuum grippers flex their artificial muscles

A short electric pulse is all it takes to generate and release a powerful vacuum in the blink of an eye. The novel vacuum gripper enables robot arms to pick up objects and move them around freely in space. The system works without the need for compressed air to generate the vacuum, it is energy efficient, quiet and suitable for use in clean rooms.

What plants can teach us about oil spill clean-up, microfluidics

For years, scientists have been inspired by nature to innovate solutions to tricky problems, even oil spills — manmade disasters with devastating environmental and economic consequences. A new study takes a cue from leaf structure to fabricate material that can separate oil and water, which could lead to safer and more efficient oil spill clean-up methods.
