Particle physics is an interesting and complicated field of study. Its theoretical framework, the Standard Model, was developed during the second half of the twentieth century and it opened he possibility to explaining the behavior of the basic blocks of the Universe. It also classified all the particles, from the electron (discovered in 1897) to […]
Imagine a very simple chemical estructure: 4 carbon and 1 nitrogen forming a ring, with no double bonds, just simple bonds between any two of them and with hydrogen. This compound is called pyrrolidine and is the base of very important biological and farmacological products. Pyrrolidine is found naturally in the leaves of tobacco and […]
Charles Lullin knew that the figures and people he was seeing were illusions. It was 1759, Charles Lullin was almost ninety years old and he had lost most of his vision: he was still able to distinguish some objects but he was not able to read or write. A servant used to read him the […]

Faster. That is the word that describes de evolution of electronics. Any new development has to be faster than anything before, if it is going to cope with the huge amount of information that the device where it may be incorporated will have to process in almost no time. Graphene has just demonstrated once again […]
The other day I came across an article about the revolution of cultured meat at El País Semanal, although that was not the first time I read about this. Still, I have to admit is such a shocking subject that I thought it may deserve a post explaining how advanced this technology is at the […]
A topological insulator is a material in which there is order associated to topology, i.e., the surface can conduct electricity but the bulk of the material is an insulator. In these last years topological insulators have received the attention of a large area of the scientific community thanks to their exotic properties. They are promising […]
Geometrical structure, lattice periodicity and atomic arrangement are subtly intertwined with the electronic properties of materials. Sub-angstrom changes in the atomic distance are sufficient to modify the physical and chemical properties, such as the band-structure, carrier mobility and the chemical reactivity. The deposition of two-dimensional layered crystals on mechanically stretchable or bendable substrates can produce […]

When we study for the first time the structure of the atom in high school we encounter for the first time the concept of quantum excitation. We learn that excitation is the process in which a nucleus, electron, atom, ion, or molecule acquires energy that raises it to a quantum state (the excited state) higher […]
Author: Shu Ning got her BSc degree in Pharmacy from Shenyang Pharmaceutical University (China) in 2014. In 2016, she obtained her Master of Research degree on Clinical Research – Translational Medicine – at Imperial College London (UK) where she has worked on mitochondrial dysfunction in pulmonary smooth muscle cells from Pulmonary Arterial Hypertension. Currently she […]
Vacuum birefringence may have been observed in neutron star A neutron star seen with the European Southern Observatory’s Very Large Telescope may have given scientists the first look at a quantum effect predicted back in 1930 but never observed before. “The high linear polarization that we measured with the VLT can’t be easily explained by […]
