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 can be found all […]

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 […]

Nowadays, central Australia is mostly a huge desert. It was not always like that: only five million years ago, this area had a completely different look, with humid forests, rivers, streams and lakes, a strong contrast to the current dry […]

Back in the decade of 1950, and inspired by the beauty of the formulation of Quantum Electrodynamics, carried out by Feynman among others in the first half of the twentieth century; scientists thought that all physics had to be invariant […]

In biology few issues are as basic as the division and classification of living things. Despite the differences shown by taxa that occupy each of the categories, all living things have a common ancestor and characteristics that unite them. Since […]

Nowadays there are quite a few compounds in clinical trials to assay their potential as breast cancer treatments. Some of them are the so called “PARP inhibitors”. These inhibitors work very well in tumours that have a deficiency in […]

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 […]
