Friday Squid Blogging: NGC 1068 Is the “Squid Galaxy”

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/05/friday-squid-blogging-ngc-1068-is-the-squid-galaxy.html

I hadn’t known that the NGC 1068 galaxy is nicknamed the “Squid Galaxy.” It is, and it’s spewing neutrinos without the usual accompanying gamma rays.

Friday Squid Blogging: US Naval Ship Attacked by Squid in 1978

Interesting story:

USS Stein was underway when her anti-submarine sonar gear suddenly stopped working. On returning to port and putting the ship in a drydock, engineers observed many deep scratches in the sonar dome’s rubber “NOFOUL” coating. In some areas, the coating was described as being shredded, with rips up to four feet long. Large claws were left embedded at the bottom of most of the scratches.

Friday Squid Blogging: Pet Squid Simulation

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/05/friday-squid-blogging-pet-squid-simulation.html

From Hackaday.com, this is a neural network simulation of a pet squid.

Autonomous Behavior:

  • The squid moves autonomously, making decisions based on his current state (hunger, sleepiness, etc.).
  • Implements a vision cone for food detection, simulating realistic foraging behavior.
  • Neural network can make decisions and form associations.
  • Weights are analysed, tweaked and trained by Hebbian learning algorithm.
  • Experiences from short-term and long-term memory can influence decision-making.
  • Squid can create new neurons in response to his environment (Neurogenesis)

Friday Squid Blogging: Squid and Efficient Solar Tech

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/04/friday-squid-blogging-squid-and-efficient-solar-tech.html

Researchers are trying to use squid color-changing biochemistry for solar tech.

This appears to be new and related research to a 2019 squid post.

New research:

An associate professor of chemistry and chemical biology at Northeastern University, Deravi’s recently published paper in the Journal of Materials Chemistry C sheds new light on how squid use organs that essentially function as organic solar cells to help power their camouflage abilities.
