unintended finding begs the question of just how many more animals can age in reverse.<\/p>\n<p>\u201cThe work challenges our understanding of early animal development and body plans, opening new avenues for the study of life cycle plasticity and rejuvenation. The fact that we have found a new species that uses this peculiar \u2018time-travel machine\u2019 raises fascinating questions about how spread this capacity is across the animal tree of life,\u201d said study co-author Joan J. Soto-Angel in a\u00a0statement <a href=\"https:\/\/phys.org\/news\/2024-10-young-jellies-age-reverse.html\">per Phys.org<\/a>.<\/p>\n<aside class=\"single__inline-module aligncenter wp-block-nypost-editor-primary-tag\">\n<\/aside>\n<p>Soto-Angel and her team ran experiments in an attempt to recreate the circumstances that led the comb jellyfish to revert to its infancy, identifying extreme stress as the trigger.<\/p>\n<aside class=\"single__inline-module alignright\">\n\t<\/aside>\n<p>\u201cWitnessing how they slowly transition to a typical cydippid larva as if they were going back in time, was simply fascinating,\u201d said Soto-Angel. \u201cOver several weeks, they not only reshaped their morphological features, but also had a completely different feeding behavior, typical of a cydippid larva.\u201d<\/p>\n<p>Previous research suggests that comb jellyfish may have been the first animal species to appear on Earth 700 million years ago, and may indeed owe its longevity to their ability to reverse growth and development.<\/p>\n<p>\u201cThis is a very exciting time for us,\u201d said Paul Burkhardt, who co-wrote the study. \u201cThis fascinating finding will open the door for many important discoveries. It will be interesting to reveal the molecular mechanism driving reverse development, and what happens to the animal\u2019s nerve net during this process.\u201d<\/p>\n<p>In the future, similar findings could lead scientists to understand how humans, too, might harness the aging process. <\/p>\n<\/p><\/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:\/\/nypost.com\/2024\/11\/10\/science\/time-traveler-jellyfish-can-age-in-reverse-accidental-discovery\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Most living creatures are bound by the fact of birth, aging and death.
