Grantland Rice

Grantland Rice (1880-1954), American sportswriter and poet of the Gee Whiz school, wrote the Four Horsemen lede of 1924 and 'how you played the Game,' syndicated in over 100 newspapers.

Grantley Adams

Grantley Adams (1898–1971) was a Barbadian lawyer and politician who served as the first Premier of Barbados and the only Prime Minister of the West Indies Federation.

Grantley Adams International Airport

Grantley Adams International Airport, formerly Seawell Airport, is the sole airport of Barbados, located at Seawell in Christ Church and serving as an aviation hub for the Eastern Caribbean.

Grantley W. Taylor, full name Grantley Walder Taylor, was an American surgeon and cancer researcher at Harvard and Massachusetts General Hospital, known for work on lymph-node metastases and hindquarter amputation.

Grants Pass, Oregon

Grants Pass, Oregon: county seat of Josephine County on the Rogue River, incorporated 1887, population about 39,000; named for Grant's Vicksburg victory; home of Dutch Bros and the 2024 Johnson v. Grants Pass Supreme Court ruling.

Granular (software)

Granular is a farm management software company founded in San Francisco in 2014, acquired by DuPont for a reported $300 million in 2017 and now owned by Corteva Agriscience.

Granular activated carbon

Granular activated carbon (GAC) is a treatment material of porous carbon particles that removes dissolved contaminants from water and air by adsorption, widely used for organic contaminants and PFAS.

Granular activated carbon adsorption

Granular activated carbon adsorption is a water treatment process in which dissolved contaminants attach to porous carbon granules with surface areas of about 1,000 square meters per gram.

Granular aluminum Josephson junctions

Granular aluminum Josephson junctions are the superconducting tunnel contacts between nanoscale aluminum grains in granular aluminum, a self-assembled junction network used as high-impedance superinductors in qubits, amplifiers, and resonators.

Granular chain solitons

Granular chain solitons are non-dispersive pulses traveling along chains of elastic grains like steel spheres, predicted by Vitalii Nesterenko, with a fixed width of about five grain diameters.

Granular computing

Granular computing is an umbrella term for theories and techniques that solve complex problems using information granules, collections of similar objects, an approach introduced by Lotfi Zadeh in 1979.

Granular convection

Granular convection, known as the Brazil nut effect, is the circulation of shaken granular material, where particles rise in the center and sink along the walls.

Granular corneal dystrophy type I

Granular corneal dystrophy type I (GCD1, Groenouw type I, classic GCD): rare autosomal dominant TGFBI p.Arg555Trp stromal corneal dystrophy with childhood-onset breadcrumb-like corneal deposits, glare, erosions, and progressive visual impairment.

Granular corneal dystrophy type II

Granular corneal dystrophy type II (GCD2, Avellino corneal dystrophy) is an autosomal dominant TGFBI (R124H) stromal corneal dystrophy with hyaline and amyloid deposits, common in East Asia, exacerbated by refractive surgery, treated with PTK and keratoplasty.

Granular jamming

Granular jamming is the reversible transition of granular material like coffee grounds from a fluid-like to a solid-like state under vacuum, used widely in soft robotic grippers.

Granular material

A granular material, or granular matter, is a collection of macroscopic solid particles like sand, salt, and powders that interact through contact forces and behave as solids, liquids, or gases.

Granular metamaterials

Granular metamaterials are engineered materials whose unusual wave properties arise from ordered arrangements of discrete grains in contact, supporting applications like vibration absorption and shock protection.

Granularity

Granularity, also known as coarse-graining, is the fineness of the smallest steps a measuring system can distinguish, formally called resolution; internal noise and friction limit it.

Granulation (jewellery)

Granulation is a jewelry decoration technique in which minute grains of gold or silver are fused to a surface of the same metal, mastered by Etruscan goldsmiths of the first millennium BCE without visible solder.

Granulation tissue

Granulation tissue is vascular connective tissue of new capillaries, fibroblasts, and macrophages that fills wounds healing by secondary intention, forms days 3-10 after injury, matures into scar, and can overgrow as hypergranulation (proud flesh).

Granule cell

Granule cell: a very small vertebrate CNS neuron; covers cerebellar granule cells (parallel fibers, mossy fiber input), axonless GABAergic olfactory bulb granule cells, and dentate gyrus principal neurons doing pattern separation.

Granulin

Granulin: cysteine-rich ~6 kDa peptide motif (12 cysteines, 6 disulfide bonds) released from progranulin (PGRN), an 88 kDa secreted glycoprotein encoded by GRN; linked to frontotemporal dementia, CLN11, lysosomal function, inflammation, wound repair, and cancer.

Granulite

Granulite is a high-grade metamorphic rock with an even granular texture and hydroxyl-free minerals, also naming the granulite facies formed at 700 to 1100 °C.

Granulocyte

Granulocyte: white blood cell with enzyme-containing cytoplasmic granules; types are neutrophils, eosinophils, and basophils (sometimes mast cells). Formed in bone marrow, normal count 1,500-8,500/µL, classified by Ehrlich's 1879 dye staining.

Granulocyte-macrophage colony-stimulating factor

CSF2 (GM-CSF, granulocyte-macrophage colony-stimulating factor) is a human cytokine gene at 5q31 controlling granulocyte and macrophage production; its receptor uses shared beta-c/Jak2 signaling, and recombinant sargramostim treats neutropenia and radiation injury.

Granuloma

A granuloma is a compact cluster of immune cells, chiefly epithelioid macrophages and giant cells, formed when the body cannot eliminate an infection, foreign object, or other persistent stimulus.

Granuloma annulare

Granuloma annulare (GA), or necrobiotic papulosis, is a benign inflammatory skin disease with annular plaques and necrobiotic granulomas. Subtypes include localized, generalized, subcutaneous, and perforating; no FDA-approved treatments exist, though JAK inhibitors show promise.
