Required fields are indicated by an asterisk (*) Wolves cooperate but dogs submit, study suggestsA new study comparing dogs and wolves has a surprising conclusion: Wolves are the more tolerant and cooperative species. Dogs, in contrast, form strict dominance hierarchies and demand obedience from lower ranking pack members. As wolves became dogs, the study suggests, they weren’t selected for a cooperative nature—they were bred to follow orders.Poaching drives overall elephant decline in AfricaA spike in poaching has tipped the African elephant into decline, a new study finds. As many as 40,000 elephants were killed in 2011, a 3% loss to the total number of elephants on the continent.China pulls plug on genetically modified rice and cornChina has decided not to renew biosafety certificates that allowed research groups to grow genetically modified (GM) rice and corn. The reasoning behind the move is not clear, and it has raised questions about the future of GM research in the country.Animal speech shows similarities to human languageAnimal sounds have long been considered fundamentally different from human language—indeed, so different that scientists haven’t been able to find any intermediate evolutionary steps between animal calls and language. Now, a new study reveals that the calls of animals contain more languagelike characteristics than previously believed—and that the gap between human language and animal calls is not so wide after all.The star that exploded at the dawn of timeAstronomers have discovered an ancient star just a thousand light-years away from Earth that may be preserving cosmic shrapnel from the death of one of the very first stars born after the big bang. If confirmed, the finding means that some of the universe’s first stars were so massive they died in exceptionally violent explosions that altered the growth of early galaxies.last_img
