This discovery comes from an unlikely source: planarian flatworms. These aquatic, slithering pancake versions of worms are famous for their ability to survive dismemberment and grow whole new organisms from the sliced-up segments of their formerly unified body. Understanding how these flatworms' immune systems have managed to endure for hundreds of millions of years could hold important insights for modern medicine. https://phys.org/news/2026-06-flatworms-reveal-immune-cells-tissue.html Evolution Tue, 02 Jun 2026 11:00:07 EDT news699543121 The Mexican axolotl (Ambystoma mexicanum) is famous because adults look like overgrown babies, or tadpoles, retaining juvenile features as adults and capable of remarkable regeneration of lost limbs or tails. New studies at the National Autonomous University of Mexico have revealed a new species related to this living form. https://phys.org/news/2026-05-fossil-salamander-species-famous-axolotl.html Plants & Animals Tue, 26 May 2026 17:40:01 EDT news699005399 For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But new research from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) suggests that this limitation may not be permanent. Instead, the capacity for regeneration may still exist—hidden within the body's normal healing process. https://phys.org/news/2026-04-humans-regrow-tissue-science-closer.html Cell & Microbiology Thu, 23 Apr 2026 15:00:01 EDT news696165421 Investigating a common gene in three very different species—salamanders, mice and zebrafish—scientists have discovered the potential for a novel gene therapy aimed at eventually regrowing limbs in humans, according to new research published this week. https://phys.org/news/2026-04-regrowing-human-limbs-salamander-gene.html Biotechnology Thu, 16 Apr 2026 14:40:07 EDT news695562421 New research by an interdisciplinary team in Lithuania has revealed a promising and unconventional approach to cartilage regeneration.
