Reading a neural network’s mind

A new analytic technique sheds light on inner workings of neural networks trained to perform natural-language-processing tasks, and even suggests possibilities for improving the performance of machine-translation systems.

Microbots can clean up polluted water

(Phys.org)-A new study shows that a swarm of hundreds of thousands of tiny microbots, each smaller than the width of a human hair, can be deployed into industrial wastewater to absorb and remove toxic heavy metals. The researchers found that the microbots can remove 95% of the lead in polluted water in one hour, and can be reused multiple times, potentially offering a more effective and economical way to remove heavy metals than previous methods.
