What’s your favorite color?
Mine is red, but I’ve been really into yellow lately…though, I’m colorblind, so who knows?!

Arm Brains
Octopuses arms literally have minds of their own. A recent study looked into how each appendage’s ANC works.
ANC = Axial Nervous Cord
Acts like a spinal cord in each arm
Locally processes motor commands
Each arm contains more neurons than the brain 🤯 and operates even after being severed. Better understanding how octo-arms “think” will help us improve the functionality of soft robotics for medical use. And increase cafe robot efficiency!
Quick! (vote)What are octopuses better at? |

Rocket Oops
It’s a bird, it’s a plane, it’s a…blown up Starship crashing towards us? On Thursday, SpaceX lost a rocket over the Caribbean, but Mechazilla managed to catch its booster.
Mechazilla = launch tower w/ mechanical arms
Starship + booster = 397’ tall (Statue of Liberty = 305’)
Starship disintegrated after engine problems
This was the 2nd successful catch of their 600k-lb. booster, but Starship’s debris caused air traffic control issues and a brief scare over some islands. SpaceX is reviewing the cause ahead of more tests to make 2026’s Mars launch window.
Dr. Cicada
Cicadas could revolutionize medical equipment. Researchers uncovered how the periodic pests’ wings naturally kill bacteria.
Wings are covered w/ microscopic nanopillars
Shreds bacteria membranes
Synthetic nanopillars killed 98% of bacteria (similar to bleach)
They also prevented biofilm formation, often a shortcoming for bleach and other disinfectants. Further development aims to bring costs down to test nanopillar surfaces on a commercial scale. I just hope the pillars aren’t as loud as cicadas.

Bee’s Knees productivity has been through the roof since st3v installed octo-inspired ANC on his spare arms! Still tinkering with the nav module though.
