When people think of particle accelerators, they tend to think of giant structures: tunnels many miles long that electrons and protons race through at tremendous speeds, packing enormous energy.

But scientists in California think small is beautiful. They want to build an accelerator on semiconductor chips. An accelerator built that way won't achieve the energy of its much larger cousins, but it could accelerate material research and revolutionize medical therapy.

First of all, what is an accelerator?

The United States and China have started their trade war, and it's not clear how long it will last or how it will end.

Economists largely agree that the tariffs used to fight trade wars are destructive, and that the destruction is amplified by the retaliations and escalations of each side.

The future of how you interact with computers depends on a technology that's more than 3,000 years old. It's a technology you already use every day, on your smartphone, your TV, in your home, your car and most likely at work. It's even in the wires that bring you Internet service at near-light speed.

It's glass.
