In the real world, children learn new information by participating in classrooms, interacting with their family and friends, and watching educational videos. While previous neuroimaging research has typically used simple tasks and short-lasting stimuli, in a new study published in PloS Biology researchers examined brain development using a more complex and naturalistic educational stimulus. Children […]

First brain cells found devoted to selective attention in an invertebrate animal. Dragonflies lack humans’ big brains, but they still get the job done, according to new research that suggests that these insects have brain cells capable of feats previously seen only in primates. Specifically, the dragonflies can screen out useless visual information to focus […]

The lifespan of words A recent analysis has found that as a language grows over time, it becomes more set in its ways. New words are always being added, according to this study, but few become widely used and part of the standard vocabulary. The scientists found that as the vocabulary of a language grew […]

From the genetic point of view, when should a man be more interested in caring for his sister’s children than his wife’s? A quantitative analysis of Alan Rogers, University of Utah, shows that this behaviour should be the choice in populations where adultery is common or permitted. In the animal world, males caring for offspring […]

Five hundred phases Condensed matter physics – the branch of physics responsible for discovering and describing most of these phases – has traditionally classified phases by the way their fundamental building blocks – usually atoms – are arranged. The key is something called symmetry. Classifying the phases of matter by describing their symmetries and where […]

Three new primate species verified in Borneo A new small primate with a toxic bite and distinctive facial fur markings has been discovered in the jungles of Borneo. Two previously known subspecies of slow loris have also been accorded full species status. The slow loris (Nycticebus) is a primate genus closely related to the lemur […]
