Moon Jelly, Jellyfish. Jellyfish are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.

Human brain organoids are small balls of human brain cells ranging in size from a poppy seed to a pea. Their organization, structure and electrical signaling are similar to brain tissue. Because these brain organoids can survive in a controlled environment for months, diseases of the nervous system can be studied over time. Brain organoids have been used as models to study Zika virus infection, Alzheimer's disease and Down syndrome.
