Electronics on paper
At the moment the costs are still too high for them to be used in things like business cards or package labels, but remarkable advances in materials science and simpler fabrication methods are setting the stage for […]

Your molar roots are leftovers from Homo erectus
Adult human molar roots form for at least a year before erupting from the gum line, according to research published in the journal PLoS ONE. Researchers say the majority of the formation […]

Could Earth be constantly crashing through dark matter?
Scientists are looking to new techniques to search for evidence that the Earth is constantly breaking through walls of dark matter. Researchers are acting on a theory that dark matter, made up […]

Anyone can find an exoplanet
A team of volunteer amateur astronomers has discovered evidence of 42 alien planets. The volunteers were sorting through NASA data as part of the Planet Hunters crowdsourcing program. Professional astronomers have yet to confirm the […]

 
When a standard kilogram is not a kilogram
Tens of micrograms worth of surface contamination have caused the international standard kilogram to gain weight, according to new research, causing concern that each country’s standard weight for a kilogram is […]

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 […]

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 […]

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 […]

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 […]

 
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 […]
