Horn removal through gene editing is a win-win both for the animal and for the farmer, says Muir, who did not take part in this research. "These findings show that you can take highly desirable genes from animals and move them to other members of their species," he told Popular Science. "One could achieve the same results with natural breeding, but gene editing greatly speeds up the process, reducing the time it takes to accomplish the goal from centuries to years."

The Food and Drug Administration just approved the AquAdvantage Salmon, a fish genetically engineered to grow more quickly than its conventional counterparts. It's the first GMO animal for human consumption approved for sale in the United States.

A paper published today in Science Advances just might change that. By creating a reliable method of studying viruses' long evolutionary history-hitherto nearly impossible-researchers have found new evidence that strongly suggests viruses are indeed living entities.

The data comes from the open Tree of Life Project, a collaboration among biologists and other scientists around the world. It contains decades' worth of work in phylogeny, evolutionary history of and relationships among groups of organisms. The project is about a year away from a complete tree of all life, Rosindell said. He wanted a system in place that could visualize it as soon as it's ready. Right now, OneZoom only contains mammals, but that's still more than 5,000 species, all correlated with each other and color-coded according to their threat levels. Rosindell has big plans for the rest, and he even wants to build a searchable app for smartphones, showcasing the history and relationships between all life on Earth.
