Encyclopedia

Jellyfish or sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are not mobile, being anchored to the seabed by stalks. The bell can pulsate to provide propulsion and highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle; the medusa is normally the sexual phase, the planula larva can disperse widely and is followed by a sedentary polyp phase. — Wikipedia

Jellyfish (Encyclopædia Britannica)

Medusozoa is a clade in the phylum Cnidaria, and is often considered a subphylum. It includes the classes Hydrozoa, Scyphozoa, Staurozoa and Cubozoa, and possibly the parasitic Polypodiozoa. Medusozoans are distinguished by having a medusa stage in their often complex life cycle, a medusa typically being an umbrella-shaped body with stinging tentacles around the edge. With the exception of some Hydrozoa (and Polypodiozoa), all are called jellyfish in their free-swimming medusa phase. — Wikipedia

    A team of researchers from Fudan University and Université de Lorraine has built a model that can predict the wrinkle patterns that will develop on toroidal structures if they expand or contract. In their paper published in the journal Physical Review Letters, the group describes using one type of mathematical model to develop another model that describes how growing or contracting impacts the surfaces of toroidal structures.

    Researchers at Hokkaido University in Japan have combined natural squid tissues with synthetic polymers to develop a strong and versatile hydrogel that mimics many of the unique properties of biological tissues. Hydrogels are polymer networks containing large quantities of water, and are being explored for many uses, including medical prosthetics, soft robotic components and novel sensor systems.

    Achieving immortality is something that has driven human beings throughout much of their history. Many peculiar legends and fables have been told about the search for the elixirs of life. Medieval alchemists worked tirelessly to find the formula for the philosopher's stone, which granted rejuvenating powers. Another well-known story is the travels of Juan Ponce de León, who, while conquering the New World, searched for the mysterious fountain of youth.

    With its powerful digging shovels, the European mole can burrow through the soil with ease. The same applies to the Australian marsupial mole. Although the two animal species live far apart, they have developed similar organs in the course of evolution—in their case, extremities ideally adapted for digging in the soil.
