Life on other planets is often considered to be the stuff of science fiction. But we are one step closer in the hunt for extra-terrestrial life as an Earth-sized planet has been found to be orbiting our nearest star, Proxima Centauri. Hidden in a Name The names we give things in the natural world often contain clues about what they look like, how they behave or where they come from. But with thousands of human languages approaching extinction, important plant knowledge may die with them. Trump’s Wall and Wildlife US presidential candidate, Donald Trump’s plan to build a wall across the entire US-Mexican border would mean bad news for the fragile ecosystem of this important wildlife area. The border area is home to a diverse population of mammals, birds and plants—including a number of iconic and rare species. Freedom of movement across the border is crucial for habitat connectivity and genetic diversity. A number of species, including Desert bighorn sheep, black bears and the iconic roadrunner, would be at risk from the proposed construction. (Photo: ESO/M.
