Did you know researchers from University of Pennsylvania School of Engineering and Applied Science, say that they have created the first optical transistor?

In an open-access paper published in Nature Communications, Ritesh Agarwal, a professor the University of Pennsylvania School of Engineering and Applied Science, and his colleagues say that they have made significant progress in photonic (optical) computing by creating a prototype of a working optical transistor with properties similar to those of a conventional electronic transistor.*

Optical transistors, using photons instead of electrons, promise to one day be more powerful than the electronic transistors currently used in computers.

No, I didn't.
That's pretty cool.
Once again Science Fiction predicted it.
As I recall, the computers on the Enterprise in 'Star Trek' were photonic.

Speaking of computers, I think one of my fans in my new computer is faulty. It makes an abnormal noise until it warms up. That just started over the last couple of days.
Looks like I'll be calling the techies at the store.

Yeah, I think there's a 6 month or year limited warranty.
That should cover things like fans.
I've never had so many fans in a computer.... 6.
I might buy some replacements myself for down the road.
After a couple of years, the right parts can be hard to find.
They'd rather you buy a new machine.

It is still under warranty and the company should fix for you.
