# gst: even a single bubble can produce creative musical outcomes

<< Producing original and arranging existing musical outcomes is an art that takes years of learning and practice to master. Yet, despite the constant advances in the field of AI-powered musical creativity, production of quality musical outcomes remains a prerogative of the humans. Here we demonstrate that a single bubble in water can be used to produce creative musical outcomes, when it nonlinearly oscillates under an acoustic pressure signal that encodes a piece of classical music. >>️

AA << test whether a brood parasitic cuckoo manipulates host perception of predation risk using an acoustic signal—a hawk-like call—that might misdirect host defences and thereby reduce the chance that hosts detect parasitism >>

AA << propose that the female cuckoo chuckle call tricks the hosts into responding vigilantly as if they were exposed to danger from a hawk, instead of from a cuckoo. This would divert host attention from clutch protection to self-protection, and so reduce the chance of the hosts detecting that they have been parasitized >>

# s-phyto: versatile SERK1, in shedding and growing ...

<< During  their  life,  plants  constantly  renew  themselves.  They  sprout  new  leaves  in  the  spring  and shed  them  in  the  fall.  >>

<< When  it  is time  to  shed  an  organ,  a  small  hormone  binds  to  this  membrane  receptor  and,  together  with  a helper  protein,  the  abscission  process  is  initiated. >>

<< To  fully  initiate  the abscission  process,  another  player  is  needed:  the  helper  protein  SERK1. >>

<< The  fascinating  thing  about  SERK1  is  that  it  not  only  plays  a  role  in  the  shedding  mechanism  of plant  organs,  but  also  acts  together  with  other  membrane  receptors  that  regulate  totally  different aspects  of  plant  development >>

<< Indeed,  SERK1  is  a versatile  helper  protein  shared  between  different  signaling  pathways.  When  bound  to  another protein  receptor,  it  can  also  for  example  signal  the  plant  to  grow. >>

# s-behav: the intricate performance (dancing and singing) of a jumping spider

AA << present behavioral and neurophysiological evidence that [Jumping spiders (Salticidae)]  perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large (∼3 m) and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level (SPL) >>

<< Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds (80 Hz; 65 dB SPL) by freezing—a common anti-predatory behavior characteristic of an acoustic startle response >>

<< Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones (80 Hz at ∼65 dB SPL)—recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain.  Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. >>
