A four-year-old female Malayan tiger has tested positive for COVID-19, with six other tigers and lions showing symptoms. It’s the first known case of a ‘wild’ animal catching the disease.
A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
One big challenge for gene therapies is delivering DNA or RNA safely to cells inside patients’ bodies. New nanoparticles could be an improvement over the current standard – repurposed viruses.
New genetic technologies are letting us look at flu evolution right where it starts: within individual people, while they’re sick.
