These animals, such as flatworms, salamanders and zebrafish, are not at all closely related, suggesting that the ability to regenerate goes far back in evolutionary time. Is it possible to find a common set of genes for regeneration, that could unlock a new understanding of this process?&nbsp;</p> August 19, 2024 - 2:57pm Andy Fell /blog/no-evidence-common-set-regeneration-genes Modern Plants Show More Insect Damage Than Fossilized Plants /blog/modern-plants-show-more-insect-damage-fossilized-plants <p>Despite widespread insect declines, plants are experiencing “unprecedented levels of insect damage” in comparison to their fossilized counterparts, according to new research by a trio of scientists including ٺƵ entomologist&nbsp;<a href="https://entomology.ucdavis.edu/people/emily-meineke">Emily Meineke</a>.&nbsp;</p> October 14, 2022 - 4:26pm Andy Fell /blog/modern-plants-show-more-insect-damage-fossilized-plants Discovering Sirtuin Longevity Proteins in Early Branches of Animal Life /curiosity/news/discovering-sirtuin-longevity-proteins-early-branches-animal-life <p><span><span><span><span><span><span><span><span>Animals on the early branches of the tree of life, such as jellyfish and sea sponges, defy the usual conventions of aging.</span></span></span></span></span></span></span></span></p> September 22, 2022 - 11:45am Andy Fell /curiosity/news/discovering-sirtuin-longevity-proteins-early-branches-animal-life First Jellyfish Genome Reveals Ancient Beginnings of Complex Body Plan /curiosity/news/first-jellyfish-genome-reveals-ancient-beginnings-complex-body-plan-0 <p>Jellyfish undergo an amazing metamorphosis, from tiny polyps growing on the seafloor to swimming medusae with stinging tentacles.
