Science. Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. In an older and closely related meaning (found, for example, in Aristotle), "science" refers to the body of reliable knowledge itself, of the type that can be logically and rationally explained. Since classical antiquity science as a type of knowledge was closely to philosophy. #scie

Sensory neurons | TIME | Microscopic scenes from our amazing planet, Nikon’s Small World competition reveals more than meets the eye. Sensory neurons are typically classified as the neurons responsible for converting various external stimuli that comes from the environment into corresponding internal stimuli. They are activated by sensory input (vision, touch, hearing, etc.), and send projections into the central nervous system that convey sensory information to the brain or spinal cord.#Science

Leaf | Microscopic scenes from our amazing planet, Nikon’s Small World competition reveals more than meets the eye. A leaf is an organ of a vascular plant, as defined in botanical terms, and in particular in plant morphology. Foliage is a mass noun that refers to leaves as a feature of plants. #Nature #Science

Leaf Morphology | Typically a leaf is a thin, flattened organ borne above ground and specialized for photosynthesis, but many types of leaves are adapted in ways almost unrecognisable in those terms: some are not flat (for example many succulent leaves and conifers), some are not above ground (such as bulb scales), and some are without major photosynthetic function (consider for example cataphylls, spines, and cotyledons). #Science #Nature

Fermi Space Telescope measures cosmic fog caused by ancient starlight By Philippa Warr | Nasa's Fermi Gamma-ray #Space Telescope has been used to measure the amount of starlight that has shone in the Universe. The starlight continues to exist even when the stars themselves have ceased to shine. It's referred to as extragalactic background light (EBL) and functions as a kind of stellar fog, and has a measurable effect on the data gathered by the Fermi telescope. #Science #Technology #tech
