    Spring-Loaded Hood Orchids

    Some orchids of the genus Pterostylis have adopted rapid plant movement as a method of ensuring pollination.

    Male fungus gnats are attracted to pheromones exuded by the flower and try to copulate with the dark, furry structure known as the labellum. The labellum is attached to a sensitive elastic strap that flips upwards in response to disturbance.

    If a gnat lands on the labellum, the whole surface springs back and traps the pollinator in the hood. To escape, the insect must crawl through a small opening in the hood, brushing against the orchid’s pollinia in the process. These sticky packets of pollen adhere to the insects back.

    The insect, now carrying pollen, visits a new flower and goes through the ordeal again. This time, the pollen on the insect’s back brushes past the new flower’s stigma while the pollinator escapes, which fertilises the flower.

    Dirty thunderstorms

    A dirty thunderstorm (also, Volcanic lightning) is a weather phenomenon that occurs when lightning is produced in a volcanic plume. A study in the journal Science indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms.

When a newt loses a limb, cells in the region of the wound de-differentiate into stem cells, which then form a mass of cells called a blastema, from which the limb regrows.
