Key Points:
- A luxury handbag made from laboratory-grown collagen derived from Tyrannosaurus rex fossils was unveiled at the Art Zoo Museum Amsterdam, showcasing a novel approach to leather production.
- Scientists used ancient protein fragments from dinosaur fossils, inserted into animal cells to produce collagen, which was then transformed into leather, representing a technological advancement beyond traditional leather alternatives.
- Research on African clawed frog tadpoles revealed insights into limb regeneration, with findings suggesting that low oxygen levels accelerate wound healing and activate regenerative processes.
- The study identified oxygen-sensing molecules that play a role in triggering limb regeneration in both frogs and embryonic mice, shedding light on why most animals cannot regrow limbs.
