Cool Science thread

[ntblanks]

Cool is when a 25' 3D printer rolls by your house.

what's even cooler is what this printer prints: houses

[Dantheman]

Whoa!

[teleee]

Ok, THAT is fucking cool!

[Sluff]

There is a series on Apple TV+ called Home. One of the episodes was about the company who pioneered the 3D house printing technology. Pretty cool.

[Mazderati]

What is the media?

[Sluff]

Concrete. Needs to be just the right consistency to pump yet hold its shape. It builds up layer after layer. One house a day can be printed.

They are small houses. They go to poor areas of the world and make a small neighborhood of the houses and give them away to the locals. After they are painted and decorated, they are pretty neat.

the company is ICON. not sure what the media is, but it appears to be a specialized cement. i could take a closer look - they just printed 4 units next door.

This project is apparently their first foray into residential real estate. On an expensive lot in atx.

Not cool news but sad science news. Security camera and drone footage of the moment Arecibo's instrument array collapsed. I truly hope the US gets our scientific shit together and rebuild this.

Ya know, I've heard lots of people lamenting the loss of that array. Are we sure it was worth keeping up? In other words, was their duplicate coverage or a more modern replacement elsewhere which would have made upkeep a bad spend?

There are "passive" telescopes, but afaik Arecibo was the only radar telescope (one that can send and observe) of that size..so yes.

[From_the_NEK]

That was an incredible amount of energy letting go there. The drone closeup looking at the top of that tower really displays how violent the snapping of those cables was.

[PB]

Broken cables?!?!?

Ya know who's all over that shit .......

January 19, 2021 will go down in history as the day the greatest science headline in history--past, present or future--was published:

Back to the mundane-yet-still-cool:

Super cool. You couldn't find a better example of why basic research is so important.

I did not know they had dropped that yet. Beyond rad.

Interesting- Hudson Freeze co-taught the Molecular Glycobiology course that I took during grad school. Didn't know that he was involved with the initial work behind the characterization of Taq polymerase.

A lot of folks were involved in the development of PCR. The table was pretty much set, the only thing missing was a heat-stable DNA polymerase. Mullis was, like, "Hey, why not Taq"? I seem to recall that the (then) recent discovery of deep ocean sulfur vent-thriving bugs may have inspired him.

This was a k00l time waster- a sort of an accurately-scaled map of our Solar System. While it's t's faster to click the planetary symbols at the top, swiping is funnerer.
