Arthur T Knackerbracket has found the following story:
Xu Yi, assistant professor of electrical and computer engineering at the University of Virginia, collaborated with Yun-Feng Xiao's group from Peking University and researchers at Caltech to achieve the broadest recorded spectral span in a microcomb*.
Their peer-reviewed paper, "Chaos-assisted two-octave-spanning microcombs," was published May 11, 2020, in Nature Communications, a multidisciplinary journal dedicated to publishing high-quality research in all areas of the biological, health, physical, chemical and Earth sciences.
[...] The team applied chaos theory to a specific type of photonic device called a microresonator-based frequency comb, or microcomb. The microcomb efficiently converts photons from single to multiple wavelengths. The researchers demonstrated the broadest (i.e., most colorful) microcomb spectral span ever recorded. As photons accumulate and their motion intensifies, the frequency comb generates light in the ultraviolet to infrared spectrum.
"It's like turning a monochrome magic lantern into a technicolor film projector," Yi said. The broad spectrum of light generated from the photons increases its usefulness in spectroscopy, optical clocks and astronomy calibration to search for exoplanets.
The microcomb works by connecting two interdependent elements: a microresonator, which is a ring-shaped micrometer-scale structure that envelopes the photons and generates the frequency comb, and an output bus-waveguide. The waveguide regulates the light emission: only matched speed light can exit from the resonator to the waveguide. As Xiao explained, "It's similar to finding an exit ramp from a highway; no matter how fast you drive, the exit always has a speed limit."

What's any of this got to do with COVID-19, sonny? And where's the mask that should be on your face?? I ain't gonna stand here and let you whippersnapper infect me! I am 75 years old and I plan to live for another 75 years! Get that mask on your face before I call the police!! Now, me, I don't wear a mask because I don't like the way it sits on my chin. Get your mask on, boy!! I'm calling the police. Dang cell phone now how do you work this contraption.

They are only tangentially related - as they were both funded by the CCP under the rubric of scientific research.
"And where's the mask that should be on your face??"
The entarwebs themselves are the perfect facemask, when used correctly.
"I ain't gonna stand here and let you whippersnapper infect me! I am 75 years old and I plan to live for another 75 years!"
Your plans are moot. (You spammed my farfar, prepare to diarh? No! Shush! hear him out!)
"Get that mask on your face before I call the police!!"
Call em. Go ahead. Been dealing with them since I was 6. Better odds on them bashing you than I, SIR!
"Now, me, I don't wear a mask because I don't like the way it sits on my chin."
Oh.
Ooooh.
Ok. Pray continue.
"Get your mask on, boy!!"
Yässa mässa! Donna hurta mej mässa!
"I'm calling the police."
Oh yes, please do m'lord.
It's about time police brutality was harnessed to the general good!
(TL:DR OK BOOMER!)

You expect police brutality against a 75 year old who reports you for failure to comply with a mandatory mask order?
Truly you are a special kind of stupid.

Plus I have a face mask anyhoo. So fucka da yoo. Pardon my Frankish.
And yes, I would expect that police brutality against someone who called the cops on me for a non violation would be a more likely outcome than ultraviolence against moi. Cause I'm not an idiot. And he clearly is.
"Truly you are a special kind of stupid."
When you apes look into my posts, you see your own face staring back at you.
Boo!

Cops...? why should I call the cops? Can you hear the click my 9MM Glock 19C Gen4? It could be the last thing you hear.

But is this microcomb thing a recent finding that's seeing real-world application testing [soylentnews.org] in the lab? That would be neat.
