In the fast moving field of two dimensional materials, even a slight rotational shift between layers can dramatically change how a material behaves. Scientists previously discovered that when atom thin crystals are stacked with a small angular mismatch, their electronic properties can transform. This approach, known as moiré engineering, has become a key strategy for designing new forms of quantum matter.

A Micro-Comb is when Jeffrey Combs only plays that character for one episode.

Optical frequency combs are laser sources whose colors are evenly spaced, like the teeth of a comb. They underpin many modern technologies requiring precision measurement, from atomic clocks to high-speed telecommunications. A landmark invention in optics and the subject of the 2005 Nobel Prize in Physics, conventional fiber-laser frequency combs are stable and reliable but can be limited by bulk and expense.

The Lončar lab is at the forefront of creating chip-scale optical frequency combs, or microcombs, by shrinking these laser sources to micron-sized photonic circuits. These microcombs offer many advantages, including requiring less power and having larger comb-line spacings suited for carrying high-bandwidth data.

Shouldn't the slopped distance be considered instead of the height?

It's not guaranteed that the FCC will be built yet. But if CERN decides to build it, then these people will chip in 860M EUR.

The people in question are "a group of friends of CERN, including the Breakthrough Prize Foundation, The Eric and Wendy Schmidt Fund for Strategic Innovation, and the entrepreneurs John Elkann and Xavier Niel".

What happens as a raindrop impacts bare soil has been fairly well-studied, but what happens to raindrops afterward is poorly understood. We know that the initial splash of raindrops on soil contributes to erosion, but a new study, published in the Proceedings of the National Academy of Sciences, finds that the journey of the raindrop downhill might have an even bigger impact on erosion than the initial splash.
