Scientists have found a new species of choanoflagellate. This close relative of animals forms sheets of cells that 'flip' inside-out in response to light, alternating between a cup-shaped feeding form and a ball-like swimming form. The organism could offer clues about animals' early evolution.

Read moreThe rise of dark forms of many species of moth in heavily polluted areas of 19th and 20th century Britain, known as industrial melanism, was a highly visible response to environmental change. But did the different species rely on the same gene to adapt? New research by the University of Liverpool reveals that three species of moth, including the famous peppered moth, indeed did.
Read moreThe discovery of a nearly complete dromaeosaurid Saurornitholestes langstoni specimen is providing critical information for the evolution of theropod dinosaurs, according to new research.
Read moreBiologists have described a new species of praying mantis that displays the first documented example of conspicuous mimicking of a wasp among praying mantises.
Read moreBecause of imprinted preferences, strawberry poison frog females mate more with similar colored males, and less with differently colored males. Over time, the behavior could lead to two color types becoming separate species.
Read moreResearchers discovered that the human diet — a result of increased meat consumption, cooking and agriculture — has led to stark differences in the saliva of humans compared to that of other primates.
Read moreDifferent dinosaur groups independently evolved gigantic body sizes, but they all faced the same problems of overheating and damaging their brains.
Read moreThree simple factors that predict whether a healthy weight child will be overweight or obese by adolescence have been revealed in a new study.
Read moreWith the help of new technologies, a team has confirmed that piranhas lose and regrow all the teeth on one side of their face multiple times throughout their lives. How they do it may help explain why the fish go to such efforts to replace their teeth.
