The relationship between siblings is, for most people, the longest they will ever enjoy. It is fundamental for many of us, but especially for children, who live together regularly with their brother or sister, and where the fraternal relationship is part of daily life, of play and leisure, of learning basic skills, of emotional development […]

Plasmonic nanostructures confine light to dimensions far smaller than the free-space wavelength, as they mix optical fields with electronic excitations. It was not until the 1990s, with the appearance of accurate and reliable nanofabrication techniques, that plasmonics blossomed. It was found then that local fields around nanostructures could be directly measured by near-field scanning optical […]
Finding patterns in a text could be very useful. It could reveal if the text has been written by a certain person or not, for example. Going a step further, finding sentiments in a text or a speech can also be very handy. These skills usually appear in procedural and spy movies and TV series […]
Terahertz (THz) radiation is all around us. For example, this page emits blackbody radiation mainly in the THz region (defined here from 0.3 THz to 30 THz). Because terahertz radiation begins at a wavelength of around one millimeter and proceeds into shorter wavelengths, it is sometimes known as the submillimeter band, and its radiation as […]
Environmental problems and energy resources make it vitally important for the chemical industry to develop more sustainable and less polluting processes. Therefore, using solar energy is one of the most promising alternatives. If we take a look at Nature’s energetic profile, plants are able to use solar energy to convert it into chemical energy and […]
Symmetry is a unifying principle that governs all aspects of physics. The physical properties of crystalline solids are no different. But, as symmetry is progressively lowered through the 32 crystallographic point groups, novel transport effects emerge. Crystal symmetry dictates also the geometry of a phenomenon that has attracted a lot of attention in recent years […]
Families with members with autism spectrum disorders (ASD) are easy prey for scam artists who offer them magical solutions and therapies not backed by science. Many of these pseudotherapies are included in the so-called alternative medicine, a misnomer because they are not medical treatments and do not meet the same criteria required of a medicine: […]
Author: Jose V. Torres-Perez (@Jovitope) is a Postdoctoral Researcher at the School of Biological and Chemical Sciencies, Queen Mary, University of London (UK). This is the story of primary cilium, a cellular structure discovered at least 122 years ago. It was soon regarded as rudimentary and then forgotten for most researchers. Nonetheless, recent advances proved […]
Topological insulators are materials with special universal properties, which are protected against perturbations. Such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have conducting […]
The cerebral cortex is a limited resource. Evolution has employed some impressive tricks to increase the amount of cortex available, such as folding it, therefore getting more surface in the same volume, or putting different things in the left and right hemisphere instead of duplicating them, thus enlarging its capacity to accommodate specific functions such […]
