Why do things keep evolving into crabs?

In an act of sheer evolutionary horror, crustacean creatures continuously evolve into round, flat forms resembling crabs millennium after millennium.

Endless stream of metal music created by AI

Science Has Created Live, Endlessly Streaming AI-Generated Death Metal

What happens when you feed death metal into a neural network? Relentless Doppelganger, a 24/7 livestream of AI-generated brutality.

Dadabots is an AI band created by CJ Carr and Zack Zukowski using deep learning software. Real snippets of music by death metal band Archspire are fed through the SampleRNN neural network to create Relentless Doppelganger, a constant, livestreaming aural assault that is actually pretty listenable. If you like death metal.

As the neural network learns, it tweaks and strengthens different parts to continuously improve the music it produces. The fast and aggressive style of Archspire allows the network to create a more realistic sound.

Carr and Zukiwski have been working for years to create realistic AI-generated music.

“Most nets we trained made shitty music,” Carr told Motherboard. “Music soup. The songs would destabilize and fall apart. This one was special though.”

Listen to Relentless Doppelganger:

Slime mould solves a maze

Watch Slime Mould Solve a Maze to Find Food

Video of a slime mould finding the food in the center of the maze on the first try.

I recently stumbled upon this video of a slime mould solving a maze in one pass, and it’s either amazing or utterly horrifying nightmare fuel. The jury is still out.

According to the video description, this is a Plasmodium of Physarum polycephalum computing a path into the central chamber of the maze where the food is. It was filmed in time lapse at one frame every five minutes, and played back at 25-30 frames per second.

From the study:

Plasmodium of Physarum polycephalum is a large cell, visible by unaided eye, which exhibits sophisticated patterns of foraging behaviour. The plasmodium’s behaviour is well interpreted in terms of computation, where data are spatially extended configurations of nutrients and obstacles, and results of computation are networks of protoplasmic tubes formed by the plasmodium. In laboratory experiments and numerical simulation we show that if plasmodium of Physarum is inoculated in a maze’s peripheral channel and an oat flake (source of attractants) in a the maze’s central chamber then the plasmodium grows toward target oat flake and connects the flake with the site of original inoculation with a pronounced protoplasmic tube. The protoplasmic tube represents a path in the maze. The plasmodium solves maze in one pass because it is assisted by a gradient of chemo-attractants propagating from the target oat flake.

Curiosity Rover Photographed on Mount Sharp from Mars Orbit

Photo recently captured by NASA from Mars orbit shows the Curiosity Rover in a lonely expanse of the Red Planet.

See that blue speck? That’s the Curiosity Rover photographed by NASA in high definition from the Mars Reconnaissance Orbiter.

“When the image was taken,” NASA says, “Curiosity was partway between its investigation of active sand dunes lower on Mount Sharp, and ‘Vera Rubin Ridge,’ a destination uphill where the rover team intends to examine outcrops where hematite has been identified from Mars orbit. The rover’s surroundings include tan rocks and patches of dark sand.”

Curiosity landed on Mars August 6, 2012. According to NASA, “Lower Mount Sharp was chosen as a destination for the Curiosity mission because the layers of the mountain offer exposures of rocks that record environmental conditions from different times in the early history of the Red Planet. Curiosity has found evidence for ancient wet environments that offered conditions favorable for microbial life, if Mars has ever hosted life.”
