A rock made of shells is called a coquina, from the Spanish word for cockle. Some of the most famous coquinas are made from cockles of Shark Bay, Australia, where a species called Fragum erugatum lives in hypersaline lagoons. Because the cockles live in such extremely salty water, they essentially live without competition and can grow prolifically! The clams also symbiotically partner with algae in their bodies, so the coquinas here are basically solar-powered rocks! #clamFacts

Chinese researchers found an innovative way to use satellite constellations to detect stealth fighters, passively by detecting the “shadow” of an object between the detector and the electromagnetic radiation emitted by the satellites.

The basic idea is that when an aircraft flies through the space between Starlink satellites and ground antennas, it can cause forward scattering of the satellites’ electromagnetic waves, which can disrupt normal communication signals. 👏

@heidilifeldman @junecasagrande Even if he were joking, his action demonstrates a degree of poor judgment which should cause concern.

So apparently you can't have QR codes too close to one another or they won't work?? I was told this doesn't work, but it works fine for me. Anyone want to give it a shot, please?
Four different QR codes

Strange. None of them worked for me. I didn't know that was a problem for QR codes. TIL I guess.

I sure hope the Teamsters get with the program. There's no world in which a GOP administration isn't bad, bad, bad for unions.

#NewInkDay and #NewPenDay. Not feeling good so not able to take a good picture, but wanted to celebrate though.

The E95S M is an 'upgrade' of sorts to my currently used E95S EF.

The Plasier is a Christmas present to penable my cousin's daughter (12 yo now).

The Varsities are too carry around and penable random people.

Kon peki had just been on my want list for awhile.

I wouldn't say my body so much as my social aptitude. By home time, conversing becomes an exhausting effort. O.o
