Nickel oxide, the gray-and-black-striped material, demonstrates unique properties when exposed to hydrogen. Purdue University/Kayla Wiles

Nickel oxide is a material that can ‘learn’ like animals and could help further artificial intelligence research

The ability to store information is central to learning and the field of artificial intelligence. Researchers have shown how a unique material shows basic learning properties similar to that of slugs.

A global semiconductor shortage highlights a troubling trend: A small and shrinking number of the world’s computer chips are made in the US

The high cost and long lead times for building computer chip factories makes it difficult for the U.S. to reverse the steady decline of its domestic semiconductor manufacturing capacity.
Most of the world’s electronics are not recycled, posing health and environmental risks. catscandotcom/Getty Images

Consumer electronics have changed a lot in 20 years – systems for managing e-waste aren’t keeping up

Technical advances are reducing the volume of e-waste generated in the US as lighter, more compact products enter the market. But those goods can be harder to reuse and recycle.
