Shropshire scientists freeze animal DNA, combatting extinction

Scientists in Shropshire, England, are cryogenically preserving animal DNA, aiming to combat extinction by potentially reviving species from frozen samples. The Nature's Safe lab has cryogenically preserved genetic material from over 300 species, including sperm, eggs, and skin samples, offering a potential lifeline for endangered animals. They are working on growing red squirrel cells and have successfully produced coral sperm. This effort, while promising, is seen as a last resort, with broader conservation efforts like habitat preservation being crucial to prevent species loss, according to conservationists.
