Keeping buildings cool can use a lot of energy. Thanks to quantum computing, engineers designed a coating to cut the warming light that enters windows.
Instead of throwing unneeded things away, scientists recommend moving to a cycle of reducing, reusing, repairing and remaking old things into new ones.
Piezoelectric materials turn mechanical energy into electrical energy — and vice versa.
Tangled polymer chains help hydrogels hold their shape despite being full of water.
Sewage sludge. Cow dung. They’re not just waste — scientists are finding uses for processed poop in construction materials.
For the first time, flying drones have 3-D printed structures. In the future, such drones might be able to build in hard-to-reach places.
Super-small structures on the Arctic animals’ paws might offer extra friction that keeps them from slipping on snow, a new study concludes.
The force of friction always acts to slow things down. It depends on just two factors: the surfaces and how hard they press together.
Tiny spectrometers might someday show up on smart devices. They could help people scan for ingredients or contaminants in foods and other materials.
