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 […]

By Mario Herrero-Valea

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 under three fundamental symmetries that could relate different physical processes between them. These symmetries were […]

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 Linnaeus (in 1735) to the newest division created by Cavalier-Smith (in the late twentieth century) […]

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 […]

Where is the half of the ordinary matter in the universe not observed yet? Computer simulations of cosmological galaxy formation predict the existence of large intercluster filaments of hot and low-density gas, the so-called cosmic web. For the first time, ESA’s Planck satellite has observed one of such filaments in the merging cluster pair A399-A401 […]
