A new Australian study \u2013 conducted using high-speed videography, micro-computed tomography, and physical modeling \u2013 has revealed that the stinger functions as a unique micropump. This system employs two deformable pistons operating in antiphase within a single chamber. The dynamic deformation of the pistons allows them to alternately seal, collapse, and pass one another, enabling continuous venom flow while preventing backflow.","twitter:creator":"@apimondia","twitter:image":"https:\/\/apimondia.org\/wp-content\/uploads\/2025\/10\/apimondia-logo-small-1.webp"},"aioseo_meta_data":{"post_id":"5986","title":null,"description":null,"keywords":null,"keyphrases":{"focus":{"keyphrase":"","score":0,"analysis":{"keyphraseInTitle":{"score":0,"maxScore":9,"error":1}}},"additional":[]},"primary_term":null,"canonical_url":null,"og_title":null,"og_description":null,"og_object_type":"default","og_image_type":"featured","og_image_url":"https:\/\/apimondia.org\/wp-content\/uploads\/2026\/10\/honey-bee-stinger-.jpg","og_image_width":"1600","og_image_height":"836","og_image_custom_url":null,"og_image_custom_fields":null,"og_video":"","og_custom_url":null,"og_article_section":null,"og_article_tags":null,"twitter_use_og":false,"twitter_card":"default","twitter_image_type":"default","twitter_image_url":null,"twitter_image_custom_url":null,"twitter_image_custom_fields":null,"twitter_title":null,"twitter_description":null,"schema":{"blockGraphs":[],"customGraphs":[],"default":{"data":{"Article":[],"Course":[],"Dataset":[],"FAQPage":[],"Movie":[],"Person":[],"Product":[],"ProductReview":[],"Car":[],"Recipe":[],"Service":[],"SoftwareApplication":[],"WebPage":[]},"graphName":"BlogPosting","isEnabled":true},"graphs":[]},"schema_type":"default","schema_type_options":null,"pillar_content":false,"robots_default":true,"robots_noindex":false,"robots_noarchive":false,"robots_nosnippet":false,"robots_nofollow":false,"robots_noimageindex":false,"robots_noodp":false,"robots_notranslate":false,"robots_max_snippet":"-1","robots_max_videopreview":"-1","robots_max_imagepreview":"large","priority":null,"frequency":"default","local_seo":null,"breadcrumb_settings":null,"limit_modified_date":false,"ai":{"faqs":[],"keyPoints":[],"schemas":[],"titles":[],"descriptions":[],"socialPosts":{"email":{"subject":"","preview":"","content":""},"linkedin":[],"twitter":[],"facebook":[],"instagram":[]}},"created":"2026-10-22 21:41:21","updated":"2026-10-23 07:32:51","seo_analyzer_scan_date":null,"focus_keyword":null,"additional_keywords":null,"truseo_locale":null},"aioseo_breadcrumb":"<div class=\"aioseo-breadcrumbs\"><span class=\"aioseo-breadcrumb\">\n\t\t\t<a href=\"https:\/\/apimondia.org\/prt\/\" title=\"Home\">Home<\/a>\n\t\t<\/span><span class=\"aioseo-breadcrumb-separator\">\u00bb<\/span><span class=\"aioseo-breadcrumb\">\n\t\t\t<a href=\"https:\/\/apimondia.org\/prt\/category\/uncategorized\/\" title=\"Highlights\">Highlights<\/a>\n\t\t<\/span><span class=\"aioseo-breadcrumb-separator\">\u00bb<\/span><span class=\"aioseo-breadcrumb\">\n\t\t\tHoney Bee Stinger, an Autonomous Double Pistons Pump\n\t\t<\/span><\/div>","aioseo_breadcrumb_json":[{"label":"Home","link":"https:\/\/apimondia.org\/prt\/"},{"label":"Highlights","link":"https:\/\/apimondia.org\/prt\/category\/uncategorized\/"},{"label":"Honey Bee Stinger, an Autonomous Double Pistons Pump","link":"https:\/\/apimondia.org\/prt\/honey-bee-stinger-an-autonomous-double-pistons-pump\/"}],"_links":{"self":[{"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/posts\/5986","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/comments?post=5986"}],"version-history":[{"count":2,"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/posts\/5986\/revisions"}],"predecessor-version":[{"id":5989,"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/posts\/5986\/revisions\/5989"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/media\/5987"}],"wp:attachment":[{"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/media?parent=5986"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/categories?post=5986"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/apimondia.org\/prt\/wp-json\/wp\/v2\/tags?post=5986"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
