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 […]

Newton’s theory of gravitation assumes that the speed of gravity is infinite and the gravitational interaction is instantaneous. However, Einstein’s theory postulates that it is exactly equal to the speed of light. A team of Chinese physicists lead by Tang […]

The advances in molecular biology and the so called post-genomic era, have improved significantly the fight against many human diseases, in some cases almost leading to their eradication. However, there are still regions of our planet were people suffer from […]

We are almost sure: we have discovered the Higgs boson. Or at least, that is the most reasonable comment to do after the usual Winter Report given by the scientists that work on the two main experiments placed at the […]

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 […]

When animals eat, both the olfactory (odour) and gustatory (taste) systems send information to the brain about the food being eaten. This combined information is very valuable to determine whether the animal is about to swallow something poisonous or something […]

Quantum mechanics and biology are very different fields. The first one studies things that are very small, like atoms, molecules or particles. Biology, on the other hand, deals with complex and big systems, the living beings. Of course, that does […]

 
Easter Island is an amazingly mysterious destination due to the moais, megalithic statues resembling human figures that were built by the Rapa Nui people between the 12th and 17th centuries. These magnificent volcanic rock statues […]

 
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 […]
