A dielectric is a nonconductor of electric charge in which an applied electric field causes a displacement of charge but not a flow of charge. Light propagation through a dielectric medium is determined by the spatial distribution of the material. […]

Collagen is the newest trendy nutrient. If we search for “collagen” in the web browser, we will find a wide variety of food supplements, cosmetic products and web pages where collagen beneficial effects are highlighted. Although collagen is a […]

A placebo is a substance or treatment that does not contain any active ingredient or rest in a physiological procedure out of the placebo effect, but still achieves a real change. The placebo effect is a psychobiological phenomenon, but it […]

Electrons do not move around nuclei in defined curved orbits. Our current understanding of how electrons are to be found in atoms and molecules is based on clouds of probability called orbitals as it is not possible to give […]

Thomas C. Südhof (Göttingen, Germany, December 22, 1955) is a neurobiologist awarded in 2013 with the Nobel Prize in Medicine for his studies on the trafficking of vesicles in the cell. Südhof has just published an article in the journal […]

When light encounters molecules, the predominant mode of scattering is elastic scattering (Rayleigh). This scattering is responsible for the blue colour of the sky, for example. It is also possible for the incident photons to interact with the molecules in […]

Numerical cognition is a subdiscipline of the cognitive sciences that studies the neural, developmental and behavioral bases of the use of numbers and mathematics. It is a multidisciplinary field in which cognitive psychology, developmental psychology, cognitive linguistics and neuroscience participate. […]

Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have conducting states on their edge or surface. The conducting surface is not what makes topological insulators unique, but the fact that it is […]

A recurrent problem with pain is the absence of therapeutic strategies to selectively block the nociceptors (neurons responsible to detect painful stimuli) that need to be targeted for a particular indication. Things get even worse if we take into account […]
