A butterfly's curling feeding tube has inspired scientists to create tiny ceramic scrolls that can rapidly roll and unroll when controlled by a magnet. The...

Our eyes can switch focus almost instantly, moving from words on a page to something across the room without us even thinking about it. Recreating...

The global boom in solar power is helping countries move toward cleaner energy, but it is also creating a growing waste problem. New research suggests...

Old solar panels could become a valuable source of silver instead of ending up in landfill. Australian researchers have successfully tested a recycling process that...

The human hand is remarkably good at handling objects, from picking up a tiny needle to twisting a bottle cap. Engineers have spent years trying...

Have you ever wondered about the stuff inside batteries that powers our gadgets? A lot of times, batteries use metals that are expensive or not...

In a new paper, researchers suggest people should err on the side of caution and stop the global rollout of 5G (fifth generation) telecoms...

Princeton engineers develop a machine-learning system that bends ultrahigh-frequency signals around barriers, paving the way for faster and more reliable wireless networks. Imagine walking behind...

An electrocatalysis reactor recycles carbon dioxide to produce pure liquid fuel solutions using electricity. The scientists behind the invention hope it will become an...
