Shape-shifting computer chip thwarts an army of hackers

Most computer security focuses on software, but computer processors are vulnerable to hackers, too. An experimental secure processor changes its underlying structure before hackers can figure it out.

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.

What is a neural network? A computer scientist explains

Neural networks today do everything from cameras to translations. A professor of computer science provides a basic explanation of how neural networks work.

Increasing screen time during the coronavirus pandemic could be harmful to kids’ eyesight

With online learning and social distancing, kids are spending more time staring at screens and less time outdoors. That can put them at higher risk of myopia and serious eye problems in the future.

New technologies to recycle electronic waste

Electronic waste is accumulating and is a resource to be exploited. Microfluidic devices allow the development of recycling, including the recycling of rare earths – a precious resource.

How can we make sure that algorithms are fair?

A machine learning expert predicts a new balance between human and machine intelligence is on the horizon. For that to be good news, researchers need to figure out how to design algorithms that are fair.
