# blues; New Moon Jelly Roll Freedom Rockers. Vol. 1 (Stony Plain). Sep 4, 2020.

<< In 2007, while rolling through the American night in a ramshackle retirement home vehicle badly disguised as a tour bus, blues legend Charlie Musselwhite and North Mississippi Allstars' guitarist Luther Dickinson engaged in conversation. The younger man related Alvin Youngblood Hart's philosophical desire to live as a "freedom rocker." The wily elder bluesman listened to his words, then looked out the window and knowingly pointed at the rising moon. He replied: "New Moon Freedom Rockers." Back in Mississippi at the Zebra Ranch studio, Musselwhite and Cody and Luther Dickinson joined forces with their dad, roots rock legend Jim Dickinson (who promptly added the words "Jelly Roll" to the band's name), Alvin Hart, and Jimbo Mathus, with NMA bassist Chris Chew and Paul Taylor as guests. They circled chairs, placed mikes, and hit "record." Afterwards, the session tapes were archived. They sat in the vault until Jim Dickinson passed in 2009, and they became apocryphal. Stony Plain's Holger Peterson contacted Luther and Cody about releasing them. >>

# behav: pheromones to bamboozle bark beetles

<< While the trees are suffering due to the heat and the drought, the pests are proliferating rampantly in the warm weather: A pair of European spruce bark beetles, for example, can produce up to 30,000 offspring. >>

<< The method involves treating raw wood, i.e. harvested wood, with substances that were originally extracted from the bark beetles' pheromones. These messenger substances are not only used as a means of communication between the bark beetles themselves, they also attract predators, for example the ant beetle. >>

<< The foreign messenger substances are therefore selective: The enemies of the bark beetles are attracted by these substances, but other bark beetles are not. In the best-case scenario, the foreign substance acts as a deterrent. As larvae, the ant beetles eat the early stages of the bark beetle that burrow into the wood. These predatory beetles also patrol the bark, where they catch and eat approaching bark beetles. In this way, they can prevent or reduce the infestation. >>

<< The forest owners will no longer be buying insecticides in specialist shops, but natural substances that they can attach to stacks of raw wood, >> Michael Muller.

# gst: the generation of 'fuzzy' signals for fine skeletal muscle control

<< Minute differences in individual muscle cell contractions allow the entire muscle to flex with greater control and accuracy. Long dismissed as "noise" or error, experts now suspect that biological systems may have evolved to include unavoidable variation as a form of information in their communication channels. >>

# gst: apropos of the variety in the ways liquid jets break up

<< When a liquid exits a nozzle and encounters something it cannot immediately mix into—a gas, for example—it forms a cylinder. Quickly, small surface perturbations and various forces cause the liquid tube to break apart into droplets. The entire cylinder either pinches off into droplets one at a time at the tip, takes on a wavy or corkscrew-like structure, or atomizes into a fine spray. >> 

<< Our results show that the gas and liquid flows are equally important in the interface region, an idea neglected by most other studies, (Nathan Speirs).  The irregular shapes of the droplets formed are quite interesting as well, (Kenneth Langley) >> 

<< There's so much variety in the ways liquid jets break up. (Nathan Speirs) >>

# jazz: apropos of 'Ornithology', Charlie Parker would have turned 100y on 29 Aug 2020

<< Through Parker, complexity in jazz grew considerably. He aimed – and flew – higher, literally, by performing melodic lines that jumped to the next octave, overtly appropriating notes from a higher register. Like an alto riding piggyback on a soprano, and vice versa. This progressive musical concept required alterations in the supporting chords too. It enriched the accompanying harmonies with additional notes from these very same higher octaves. >>

# gst: self-assembly of chemistry with music

<< audible sound can control chemical reactions in solution by continuously supplying energy sources into the interface between air and the solution.  The sound-controlled air-liquid chemical interactions 'painted' intriguing and aesthetic patterns on the surface and bulk of the solution.>>

<< The Pied Piper of Hamelin tells the mythological story of a pied piper who lured rats away from the city of Hamelin by enchanting them with the music from his magical pipe. With music working like a fuel for such artistic control in chemistry, our study has shown that even synthetic molecules can exhibit life-like behavior—listening and following a musical track, >> Rahul Dev Mukhopadhyay.

# gst: behavioral teleporting as a real-time transfer of the complete ethogram of a live entity onto a remotely-located robotic replica.

AA << established "behavioral teleporting" as an experimental solution to independently manipulate multiple factors underpinning social interactions. Behavioral teleporting consists of real-time transfer of the complete ethogram of a live zebrafish onto a remotely-located robotic replica. Through parallel and simultaneous behavioral teleporting, (they) studied the interaction between two live fish swimming in remotely-located tanks: each live fish interacted with an inanimate robot that mirrored the behavior of the other fish, and the morphology of each robot was independently tailored. (They) results indicate that behavioral teleporting can preserve natural interaction between two live animals, while allowing fine control over morphological features that modulate social behavior. >>
