Converting Wi-Fi signals to electricity with new 2-D materials

Imagine a world where smartphones, laptops, wearables, and other electronics are powered without batteries. Researchers from MIT and elsewhere have taken a step in that direction, with the first fully flexible device that ...

A computational shortcut for neural networks

Neural networks are learning algorithms that approximate the solution to a task by training with available data. However, it is usually unclear how exactly they accomplish this. Two young Basel physicists have now derived ...

Green hydrogen from nature: Photocatalysis imitates plants

Green hydrogen could play a key role in the energy transition. Electrocatalytic splitting of water into hydrogen and oxygen requires huge amounts of electricity, which means the efficiency of this method for the energy transition ...

The curtailment paradox in a high solar future

Rising penetrations of variable renewable energy (VRE) in power systems are expected to increase curtailment—the reduction of renewable energy delivered due to oversupply or lack of system flexibility. But while curtailment ...

Consider workplace AI's impact before it's too late, study says

The consequences of workplace automation will likely impact just about every aspect of our lives, and scholars and policymakers need to start thinking about it far more broadly if they want to have a say in what the future ...
