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.
The black fur allele has fitness costs but also confers higher immunity against canine distemper virus, making mix-and-match mating key to population survival.
Research traces the evolution of a gene variant that reduces the risk of Alzheimer’s disease, finding that it originally evolved in response to infectious bacteria.
