STING-associated vasculopathy with onset in infancy (SAVI) is a rare genetic autoinflammatory disease, first described in 2014, causing severe skin lesions and progressive lung disease in infants.
STING1
STING1 (formerly TMEM173; protein STING, ERIS, MITA, MPYS) is the human gene at 5q31.2 encoding the ER adaptor that binds cGAMP from cGAS, drives TBK1/IRF3 type I interferon signaling, and whose mutations cause SAVI vasculopathy.
Stinger
Stinger: venom-injecting organ of bees, wasps, hornets, fire ants, and scorpions; in Hymenoptera a modified ovipositor, in honeybees barbed and autotomized to keep pumping venom.
Stinging of skin
Stinging of skin (ICD-11 ME65.3) is an unpleasant nettle-like cutaneous sensation triggered by topical preparations or stimuli most people tolerate, the hallmark of sensitive skin syndrome, tested with the lactic acid sting test and linked to small-fiber neuropathy and TRPV1.
Stingless bee
Stingless bees (Meliponini), also called meliponines, are over 500 social bee species of tropical regions with atrophied stings; they store honey in cerumen pots, produce acidic high-moisture honey, and are kept in meliponiculture since Maya times.
Stingless bee colony organization and life cycle
Stingless bee colonies are perennial eusocial nests with one dominant queen and thousands of workers, founded by swarming fission, with slow larval development of about 50 days.
Stingless bee communication and behavior
Stingless bees (Meliponini) recruit nestmates to food using pheromone trails, odor marks, and vibration rather than honeybee waggle dances, with signaling strategies varying widely between species.
Stingless bee honey
Stingless bee honey, often called pot-honey, is honey produced by stingless bees and stored in small cerumen pots; it is more acidic, more watery, and far rarer than honeybee honey.
Stingless bee nest architecture
Stingless bee nest architecture is the enclosed structure built by Meliponini bees: horizontal brood combs surrounded by an involucrum, with oval storage pots built outside it.
Stingray
Stingray (Myliobatoidei): flattened, venomous-barbed cartilaginous fish of shallow coastal seas, up to 6.5 ft and 790 lb, with ampullae of Lorenzini prey sensing; distinct from manta, eagle, and electric rays.
Stingray bay
Stingray Bay is the name of interactive stingray touch-pool exhibits at facilities such as the Phoenix Zoo (15,000-gallon cownose ray pool), Tennessee Aquarium, and Sea Life Michigan, where a 2023 study found rays more active with more visitors.
Stingray injury
A stingray injury is a wound from the barbed, venomous tail spine of a stingray, usually on the feet or lower legs of people wading in shallow water.
Stingray phone tracker
The Stingray is a Harris Corporation cell-site simulator, a surveillance device that mimics a cell tower and forces nearby phones to connect and transmit identifying and location information.
Stinkers Bad Movie Awards
The Stinkers Bad Movie Awards, originally the Hastings Bad Cinema Society, gave satirical dishonors to Hollywood's worst films each year from 1978 until the final awards for 2006.
Stinkhorn and nidularioid ecology and dispersal
Stinkhorn and nidularioid ecology and dispersal covers how gasteroid fungi spread spores they cannot launch themselves: stinkhorns lure insects with carrion-like odors, while bird's-nest fungi eject spore packets with raindrops.
Stinking badges
Stinking badges: a famous line from the 1948 film The Treasure of the Sierra Madre, spoken by Gold Hat (Alfonso Bedoya). Its paraphrase "We don't need no stinking badges" comes from The Monkees (1967) and Blazing Saddles (1974), not the film itself.
Stinky tofu (臭豆腐)
Stinky tofu (臭豆腐, chòu dòu fu) is a Chinese fermented tofu snack brined so microbes break protein into amino acids and hydrogen sulfide; famous fried Changsha (Huogongdian) and Beijing Qingfang versions differ by region and brine.
Stinson Reliant
The Stinson Reliant, also built for military use as the AT-19 Reliant, was an American cabin monoplane produced from 1933 to 1941 and known for its distinctive gull wing.
STIP1
STIP1 (Hop/Sti1, stress induced phosphoprotein 1) is a human co-chaperone gene encoding an adaptor that bridges Hsp70 and Hsp90, stimulating Hsp70 ATPase and inhibiting Hsp90 ATPase during client protein folding; secreted Hop also signals via prion protein and is implicated in cancer and neurodegeneration.
Stipa
Stipa (feather grasses, needlegrasses) is a Poaceae genus of perennial tussock grasses with twisted, hygroscopic awns; about 141 accepted Old World species, centered in Middle Asian steppes, type species S. pennata.

Stir bar sorptive extraction
Stir bar sorptive extraction (SBSE) is a sample preparation technique in which a stir bar coated with polydimethylsiloxane extracts and concentrates organic analytes from liquid samples before chromatographic analysis.
