With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
Terrestrial mammals, carnivorous plants, and even burrowing reptiles have spread around the globe by braving the seven seas. These chance ocean crossings are rewriting the story of Earth’s biogeography.
