  1. 💁🏻‍♀️ TIL: 🦈💡 A team of marine biologists measured the glow of eight kitefin #sharks caught off #NewZealand, recording brightness, #color, and shine direction.

    Most of the #light matches classic #camouflage, but the glow spreads sideways toward the nose and fins. The researchers read this as a biological searchlight, illuminating prey in the dark seafloor, while the bright dorsal fin defies any camouflage role entirely.

  3. Now would be an excellent time to inform the billionaires that it would be super futuristic and disruptive of them and their henchmen to move into underwater living chambers. Just leave out the part about it being "basically a glorified camper-van". Play up the exclusiveness of seafloor Amontillado.

  5. Magnetoelectric #antenna aims to boost #underwater comms 800 billionfold
    #BlueME's key innovation is a #MagnetoelectricAntenna, a magnetic field deforms a magnetostrictive layer made from material called #Metglas, mechanical deformation induces a voltage in an adjacent piezoelectric layer (PZT, a common ceramic used in sensors and actuators). Run process in reverse, and you have a transmitter. Result is an antenna that operates at very low frequencies, around 35–36 kHz.
