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 now slightly different. The cylinder-shaped piece of metal is key for scientific experiments that require exact […]

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 […]

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 […]

The history of science is full of examples of researchers who arrived at the same discovery independently. Unfortunately, this still happens in this information age, thus technological deficiencies are not to blame for this lack of communication between different research communities. Odd as it may sound from outside, I hold that much of this isolation […]

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 […]

Scientists have always peaked into nature in order to mimic its most interesting features into industrial processes. This adaptation process is called biomimicry, and the most recurring example is the history of how the Swiss engineer George de Mestral invented fabric hook-and-loop fasteners (Velcro) in the 1950s, after he saw how burdock seeds got attached […]
