Glitter Shrimp | Spacious Space | Pee Science
TCK #89
In Florida this week, I told someone how cool the wild lizards were since we don’t see them in Boston. The way they looked at me, you’d think I yelled “I LIKE SQUIRRELS!”
Which is also true, but like, I wouldn’t just scream that out of context…obv.

Glitter Shrimp
Glitter helps some be seen, while crustaceans become invisible. Their larvae’s shimmering eyes are the key to their hidden survival.
Many sea creatures strive for invisible infancy, but eyes give them away
Mantis shrimp evolved “disco eye-crystals” to deflect light
Making their eyes appear the same color as surrounding water
As mantis shrimp mature, these “crystals” rotate behind the eye to enhance vision similar to how cats’ reflective sight works. Researchers hope to apply this behavior to nanoparticle engineering. Or maybe just make glamorous contact lenses.
Spacious Space
NASA’s James Webb telescope has found the impossible: galaxies too large and too old to exist in our current understanding of the universe.
Webb Reminder - massive space telescope that can see into the past
Spotted 6 new spiral galaxies (like the Milky Way)
Combined mass > previously believed possible…in the entire universe
Being over 12 billion years old, these galaxies are too young to be so large given everything we thought we knew. Further research could drastically change what we think about how it all began. Literally this.
Pee Science
A new urine test can tell if you have cancer. Researchers can illuminate your pee in search of potentially deadly indicators.
Currently identifies prostate and pancreatic cancer
Utilizes urine strips for quick and easy field use
Each tests costs ~$0.76
Testing is based on identifying unique metabolites secreted by cancer cells as they spread. Researchers hope to expand testing to other cancer types and improve early detection. It could even become the #1 test.

Just Add Glitter

Apparently crustacean larvae do more than just add glitter to become invisible. At least st3v looks fabulous.
