# 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. >>

# behav: a single gene can drive aggression (in wild songbird)

<< In 2014, the lab (Donna Maney lab) identified a hormone receptor—estrogen receptor alpha (ER-alpha)—that appeared connected to the differences in the sparrows' aggression and parenting behaviors in the wild. The white-striped birds express this receptor at much higher levels than the tan-striped birds, and the more the expression, the more aggressive the bird. >>

In the recent work << results showed that when expression of that one gene was blocked, the aggression of the white-striped birds went down so they behaved like the tan-striped ones. >>

# gst: the role of surface tension during the collapse of a viscous bubble

<< The rupture and collapse of viscous bubbles are widespread in nature and in industrial applications. The phenomenon is accompanied by elastic sheets that develop radial wrinkles. While the weight of the film appeared to play a dominant role during film collapse and wrinkling instability, in this work, gravity appeared to play a surprisingly negligible role. Based on fluid mechanics of the phenomena, Oratis et al. showed surface tension to be the driving factor during collapse to initiate dynamic buckling instability and wrinkling behavior, accompanied with the breakdown of curved viscous and viscoelastic films. >>
