The magnitude of many of the exotic phenomena predicted for topological semimetals is directly proportional to something called the Chern number. Given the importance of the Chern number magnitude for these phenomena, it is just natural to wonder whether there is an upper limit for it and whether there are real materials in which this […]
“ Eat all your food, it can’t be wasted”. How many times have you heard that phrase from your parents? We did not know it, but they were right. Nowadays, a third of the food we generate is wasted. This generates both economic losses (~ $940 billion USD per year) and environmental problems (4.4 Gt […]
Gene therapy was a 90s hit. The most promising medical advance of the decade was almost forgotten after some really serious side effects occurred in one clinical trial, but after nearly 3 decades a small trial in Germany has shown gene therapy not only to be safe for use in humans but also to have […]

A new fluorescent bicolour indicator, an organic molecule, could help detect the daughter atom of a neutrinoless double beta decay. If this is achieved, there would be an explanation to the matter-anti matter asymmetry in the universe. Experiments performed in 1909 by Geiger and Marsden, also called Rutherford gold foil experiment because Rutherford was their […]
In science we try to be very precise with the wording of our texts. One of the consequences of this is that we are not afraid of repeating some words in a paragraph, or even in a sentence, if that contributes to avoid possible misunderstandings, even though it may be not recommended stylistically. Another feature […]
Author: Mikel Lezaun is professor at the University of the Basque Country – UPV/EHU where he is director of the Mathematical Technology Transfer Group Production centers for blood components have the job of supplying hospitals with the products that they need in time and strive to discard as few units as possible due to outdating […]
Until 1932, atoms were considered to consist in positive charges, called protons, located within the atomic nucleus, where the majority of the mass of the atom is concentrated, and negative charges, identified as electrons, surrounding the nucleus to make it electrically neutral. However, in 1932 James Chadwick discovered the neutron, an uncharged particle located at […]
Author: María Girbés Mínguez is a doctoral student at Center for Molecular Neurobiology Hamburg (ZMNH) / UKE (University Medical Center Hamburg-Eppendorf) A recent study published in the journal Cell Systems uncovered that bacterial communities (biofilms) can store complex patterns of information through membrane potentials at the cellular level, in a similar way to neurons. But […]
The Nobel Prize in Chemistry 2016 was awarded to Jean-Pierre Sauvage, Fraser Stoddart and Ben Feringa “for the design and synthesis of molecular machines”. Molecular machines are made by one or a few molecules linked together, comprising several hundred atoms. If a molecule can use an energy input to perform a mechanical movement (output) it […]
The Hodgkin-Huxley model for the generation of the nerve action potential is one of the most successful mathematical models of a complex biological process that has ever been formulated. Alan Hodgkin and Andrew Huxley described the model in 1952 to explain the ionic mechanisms underlying the initiation and propagation of action potentials in the squid […]
