There’s a type of knife tech often seen in science fiction that revolves around vibrating a blade to increase its sharpness. We’ve seen examples of this in franchises like Star Wars (vibroblades), Evangelion (the prog knife), Dune (pulse-swords) and the Marvel universe (vibranium), but what might surprise you is that the underlying science is sound. By vibrating a cutting tool at high frequencies, not only do you reduce friction, you essentially turn the blade into a saw, as tiny oscillations enhance the inherent sharpness of a blade.
The US Department of Defense has reportedly reached a deal to use Elon Musk's Grok in its classified systems, according to Axios.

Whether you’re on back-to-back video meetings, live streaming or just trying to look presentable on a family call, your webcam matters more than most might expect.

A dedicated webcam can noticeably improve sharpness, color accuracy and overall reliability.
