NPR reports that researchers are testing “superworms,” a large beetle larva, as a safer and efficient way to clean animal skeletons for museums and universities. The method could help institutions prepare specimens without harsh chemicals, long boiling processes, or the escape risks linked to some traditional museum beetles.
The story follows a natural history museum connected to a university in Mashhad, Iran, where donated animals created a practical storage and preparation problem. Researchers found that small groups of larvae could clean animals ranging from mice and fish to larger wild mammals, though one outside expert warned that their strong jaws might accidentally damage tiny bones.
NPR 報導，研究人員正在測試使用「superworms」（一種大型甲蟲幼蟲）來清理動物骨骼，供博物館與大學研究、教育之用。這種方法可能讓機構不必依賴刺激性化學品、耗時的水煮處理，或容易逃逸並破壞館藏的傳統甲蟲。
報導提到，伊朗 Mashhad 一間附屬於當地大學的自然史博物館，因民眾捐贈動物而面臨儲存與標本處理壓力。研究人員發現，少量幼蟲可以清理從老鼠、魚、小鳥到狼與野貓等不同大小的動物；不過，一位外部專家提醒，牠們強壯的顎部也可能不小心折斷細小骨頭。
the hard bone structures inside animals or people, especially when studied after the soft tissue is gone.
In article: “To clean animal skeletons used for research and education, scientists are turning to a new type of beetle larva.”
骨骼；動物或人體內部堅硬的骨頭結構，常指去除軟組織後可供研究的骨架。
individual examples of animals, plants, rocks, or other materials kept for scientific study or display.
In article: “With all these specimens pouring in, the research team soon ran out of space.”
標本、樣本；為了科學研究或展示而保存的個別動物、植物、岩石或其他材料。
young insects or animals in an early life stage before they become adults.
In article: “Alaei says that as long as superworms are kept together in a group, they remain as larvae, unable to wreak havoc elsewhere in the museum.”
幼蟲；昆蟲或某些動物在成為成體之前的早期生命階段。
jaw-like mouthparts, especially in insects, that are used for biting, chewing, or holding food.
In article: “Then some years ago, Alaei's colleagues in Iran turned their attention to a different organism, the superworm - a hefty, nearly finger-sized larva of another kind of beetle with large chewing mandibles.”
大顎、顎部；尤其指昆蟲用來咬、咀嚼或夾住食物的下顎狀口器。
without intending to do something; accidentally, especially when the result is unwanted.
In article: “He says that superworms may well be easier to control than dermestid beetles, but he worries their powerful mandibles could inadvertently snap a small bone.”
無意中、不小心地；並非故意卻造成某種結果，通常是不希望發生的結果。
Usage note: This is today’s stretch word. It often appears in careful scientific, legal, and policy writing when a harmful result was accidental rather than deliberate.
