Happy Monday! Come learn how jellyfish swim. In a review led by fluid dynamics maestro Alex Hoover, we outline how neuromechanical modeling will help us understand how modulation of neural activity allows jellyfish to jet and pirouette through fluids www.sciencedirect.com/science/arti...
Figure 1. The fluid dynamics of jellyfish swimming. a) Minimum intensity projection of a video clip of swimming Clytia hemisphaerica recorded at 30 fps; dark spots capture trajectories of tentacle bulbs, mouth, and gonads over time. Blue outlines approximate the margin of jellyfish on the frame of maximum extent on two successive swim pulses; green arrow shows direction of swimming. b) Minimum intensity projection of the same animal during a period of turning, showing asymmetry in the movement of bulbs on the inside vs outside of the turn. c) 3D diagram of the bell of a swimming jellyfish, showing starting and stopping vortex rings and fluid flow into (blue) vs away from (purple) the bell during the passive energy recapture phase of swimming. d) Cross section of a swimming jellyfish showing fluid vorticity toward the end of a swim pulse relaxation phase, showing locations of the starting and stopping vortex rings and the boundary layer. e) Swim pulse dynamics of an oblate jellyfish under symmetric bell contraction, producing straight swimming. The starting vortex ring is generated by active muscle contraction of the bell (ii, purple arrows), while the stopping vortex ring is generated by passive elastic relaxation (iii-iv, green arrows) from the mesoglea. Forward motion during the relaxation phase arises from the interaction of the starting and stopping vortex rings, with the starting vortex ring pulling fluid away from the bell and the stopping vortex ring directing fluid into the subumbrellar cavity. f) Swim pulse dynamics under asymmetric bell contraction, producing turning. Initially at rest (i), the neuronal signal initiates a muscular contraction in the bell margin on the inside of the turn before a stronger contraction of the bell margin is observed on the outside of the turn (ii-iii, purple arrows). The corresponding passive restoration yields a stronger expansion of the bell margin on the outside of the turn (iv, green arrows).

PSA for flood response: remember to NEVER mix cleaning solutions across classes, especially bleach x any ammonia or ammonium salts derivative (e.g. Lysol & many medical-grade spray cleaners)!! Biological hazard-graded respirators won’t protect against hazardous chemical fumes.
DO NOT MIX THESE CLEANING PRODUCTS
BLEACH + VINEGAR
Bleach and vinegar mixture produces chlorine gas, which can cause coughing, breathing
problems, burning and watery eyes.
BLEACH + AMMONIA
Bleach and ammonia produce a toxic gas called chloramine. It causes shortness of breath and chest pain.
BLEACH + RUBBING ALCOHOL
Bleach and rubbing alcohol makes chloroform, which is highly toxic.
HYDROGEN PEROXIDE +
VINEGAR
This combination makes peracetic/peroxyacetic acid, which can be highly corrosive
