I Got Hearing Aids For The First Time — And There Was 1 Surprising Side Effect
“I can actually see the shapes of the leaves on the trees!” I exclaimed to my doctor while gazing out the window. I was 12 years old and just got my first pair of glasses. My vision had been impaired long enough for me to not realize what I was missing. The same thing happened […]
Researchers unveil a secret of stronger metals: Study shows what happens when crystalline grains in metals reform at nanometer scales, improving metal properties
Forming metal into the shapes needed for various purposes can be done in many ways, including casting, machining, rolling, and forging. These processes affect the sizes and shapes of the tiny crystalline grains that make up the bulk metal, whether it be steel, aluminum or other widely used metals and alloys. Now researchers at MIT […]
High-energy shape memory polymer could someday help robots flex their muscles
When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied. These materials show great promise for soft robotics, smart biomedical devices and deployable space structures, but until now they haven’t been able to store enough energy. Now, researchers reporting in ACS Central Science have developed a shape […]
