These cool jellyfish socks for men glow in the dark, just like the bioluminescent jellies known as crystal jellies, or Aequorea victoria. Scientists love these little cnidarians because their glowing proteins are perfect for tracking genetic markers, meaning they are incredibly useful for disease research.
