“Photonic crystals” is the name that was given to periodic arrangements of materials with different refractive indexes. This name derives from the analogy between the behavior of photons in these materials and the one of electrons in the periodic structure […]

 
Humans can build and use the most sophisticated tools. One of the reasons is the configuration of our hands, which enable us to hold items in a very convenient way. But further than that, we can actually grab items […]

 
New fabric may increase access to water in deserts
A team of scientists say they’ve created a piece of fabric that can collect water from fog and release the liquid when conditions are warmer. Researchers coated a piece of […]

Olfaction is one of the most important senses. It protects us from eating spoiled food, it helps animals to detect their relatives, it makes the perfume business quite successful and, in general, it connects us to the volatile chemicals surrounding […]

We will address a recent article by Jaillet and Porta (Institut de Robòtica i Informàtica Industrial, IRI), which reveals new practical applications of highly-abstract mathematical entities.
When it comes to robots, we can’t forget that their fundamental […]

Quantum field theory has been the paradigm of modern physics since it was formulated in the first half of the last century. It is based on the idea that everything in physics corresponds to the interaction of some fundamental fields […]

Proteins perform most of the daily work of the cell, they catalyse most of the biochemical reactions, initiate and mediate the electrical signals in our neurons and form an important part of the structure of our bodies. Formed by up […]

The wave nature of light expresses itself in the propagation all over space, showing an intrinsic limitation to be localized beyond the so-called diffraction limit which is of the order of half the wavelength of the photons propagating. However when […]

Electronics on paper
At the moment the costs are still too high for them to be used in things like business cards or package labels, but remarkable advances in materials science and simpler fabrication methods are setting the stage for […]

A translucent material allows light to pass through, but if we try to look an object behind such a material, the image will appear blurred or distorted. Think, for example, of the semitransparent glasses commonly used as showers screens. The […]
