Jokura says it\u2019s possible that the first nervous system to ever evolve on Earth was inside an ancient comb jelly \u2014 a distant ancestor of the ones he was scooping out of the water.<\/p>\n<aside id=\"ad-backstage-wrap\" class=\"ad-wrap backstage\" aria-label=\"advertisement\">\n<\/aside>\n<p>He likens the search to a thrilling kind of treasure hunt. \u201cYou can definitely miss it,\u201d he says, but his trick is to look for sunlight reflecting off of their bodies.<\/p>\n<p>Jokura took the comb jellies he found back to the lab in Woods Hole and put them in a tank. One day, he went to check on them and a particular comb jelly caught his eye \u2014 one that led to a paper just published in the journal <a href=\"https:\/\/cell.com\/current-biology\/fulltext\/S0960-9822(24)01023-6\"><em><u>Current Biology<\/u><\/em><\/a>.<\/p>\n<p>\u201cI was surprised because a weird shape was there,\u201d he recalls. It was fatter. It had two heads, two mouths, and two anuses. Jokura thought to himself: \u201cOh, I think these are two individuals fused together.\u201d<\/p>\n<p>He took off at a sprint, fat comb jelly in a beaker, to show his labmates. \u201cI was like, \u2018What? That\u2019s weird,\u201d says neurobiologist <a href=\"https:\/\/neuromari.weebly.com\/\"><u>Mariana Rodriguez-Santiago<\/u><\/a> of Colorado State University. \u201cAnd so I went to see it and I was like, \u2018Oh, it is fused. Oh, and it\u2019s moving together.\u2019\u201d<\/p>\n<p>This was a striking observation \u2014 if this being was once two individuals, it was now behaving as one.<\/p>\n<p>The next thing Rodriguez-Santiago did was to poke it. \u201cI poked it mostly to see if they would get unstuck,\u201d she says. \u201cBut instead, the muscle contracted at the same time.\u201d This suggested that it had a shared nervous system.<\/p>\n<aside id=\"ad-secondary-wrap\" class=\"ad-wrap secondary\" aria-label=\"advertisement\">\n<\/aside>\n<p>The researchers went about trying to see if this little translucent fatty was an anomaly or whether they could recreate it. \u201cSo we did some Frankenstein pilot experiments,\u201d says Rodriguez-Santiago.<\/p>\n<p>They sliced comb jellies in different spots, and when they snipped them along their edges and placed them near one another, within an hour or two, they fused nine out of ten times.<\/p>\n<p>In addition, the team fed the fused jellies brine shrimp with fluorescent dye so they could keep track of the food particles. \u201cOne comb jelly ate it and it traveled through the gut of both of them and the second comb jelly pooped it out,&#8221; says Rodriguez-Santiago.<\/p>\n<p>\u201cI thought this was a really fun paper to read,\u201d says <a href=\"https:\/\/lifehistorylab.com\/\"><u>Allison Edgar<\/u><\/a>, an integrative biologist at the New Jersey Institute of Technology who wasn\u2019t involved in the research. She says comb jelly fusion has been observed before, but this is the first time that scientists have documented the individuals behaving as one.<\/p>\n<p>Edgar is excited by what this discovery might mean for humans. \u201cIf comb jellies do have this great mechanism for regenerating and healing,\u201d she says, \u201cthat would mean you could have an organ transplant with no consequences and you would heal from it very quickly.\u201d<\/p>\n<p>She says given how rapidly the two comb jellies\u2019 nervous systems became one, it could teach humans how to allow someone to regain full control over a transplanted limb, say. But she admits that kind of advance is a ways off.<\/p>\n<p>In other words, comb jellies may be transparent \u2014 but they hold secrets that are still very much opaque.<\/p>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.npr.org\/2024\/10\/08\/nx-s1-5144689\/comb-jelly-superpower-absorb-become-one\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A little more than a year ago, while biologist Kei Jokura was in Woods Hole, Mass., he routinely walked down to the water, scanning for comb jellies. \u201cThey look like &hellip; <a href=\"https:\/\/hotvideos24.online\/?p=111949\" class=\"more-link\">Read More<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8628],"tags":[],"class_list":["post-111949","post","type-post","status-publish","format-standard","hentry","category-science","entry"],"_links":{"self":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts\/111949","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=111949"}],"version-history":[{"count":0,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts\/111949\/revisions"}],"wp:attachment":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=111949"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=111949"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=111949"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
