It's easy for us to tell if someone is enjoying their meal or not. They lick their lips if they like it, grimace if they don't.

Researchers at the University of Tokyo and the Innovation Center of NanoMedicine (iCONM) have developed an artificial intelligence (AI) approach that identifies the morphology of nanoparticles in liquid using data from standard nanoparticle tracking analysis (NTA), a widely used technique for particle sizing. The method achieved classification accuracies exceeding 80% for non-spherical nanoparticles without requiring modification of existing instruments.

So … What’s Going on With Mitch McConnell?

AWOL

The 84-year-old Kentucky Republican has been in the hospital for weeks. No one can say why

We know, generally speaking, where Kentucky Senator Mitch McConnell is: in a hospital in the Washington, D.C., area. What we don’t know is why he’s there, when he will leave, and what state he is in right now.
