One of the greatest inventions of the 20th century, if not the greatest, was the transistor. It revolutionized the electronics industry and changed the way people around the world lived, learned, worked, and played. Its invention marked the beginning of solid state electronics which quickly reduced the size and power requirements of existing electronic tube […]
We all have listened about gene therapy, and for those who are old enough not in a good way, at all. Gene therapy became the most promising clinical therapy in the 1990s and this technology was meant to transform medicine. In essence, the concept of gene therapy is pretty simple: the introduction of an exogenous […]

Magnetic bands around sun may help predict solar flares Tracking the movements of traveling magnetic bands in the sun’s atmosphere may help predict solar flares, which can cause damaging power problems on Earth and wreak havoc on satellites, according to a study published in Nature Communications. Solar flares are at their worst when formed by […]
In lay people’s minds, railway lines are composed by rails and wooden sleepers on a bed of stones. These medium-sized stones are called ballast, and it is true that they are the most common material to lay the track on; at least when you are not building it in a tunnel or a bridge, where […]
A quantum dot is a nanometric crystalline structure of semiconductor materials. In a quatum dot electrons are confined in a region of space, thus creating a well defined structure of energy levels that depends very much on the size and shape of the quantum dot. This structure resembles that of atoms, that is why sometimes […]
Sensations which seem to come from limbs that had been amputated are called «phantoms». Most limb amputees report awareness of a phantom limb, i.e., the perceived presence of the missing arm or leg. Phantom sensations may also occur after the removal of body parts other than the limbs, e.g. after amputation of the breast, extraction […]

Young galaxy clusters discovered More than 200 young galaxy clusters have been documented by astronomers using data gathered by the Planck and Herschel space telescopes. The researchers have released photos of the clusters, which will be studied further in the hope answers can be found to many cosmic questions like how galaxies grow and the […]
The idea that the brain might be in a critical state has been around for a while now. Ever since neuroscientists began wondering about where the noisy neural activity recorded in vivo came from, criticality has stood up as one of the main candidates to consider. But what is criticality? The term can be traced […]
When we think about the new materials of the future some names may come to mind: pure carbon, in the form of graphene or nanotubes or buckyballs or any other exotic allotrope; or some kind of oxide of these carbon allotropes; or some strange combination of metal oxides, manufactured via processes that remind us of […]
Not many people know that polyoxometalates (POMs) discovery dates back to 1783 and that they were the D´Elhuyar brothers ( Juan José D´Elhuyar (Logroño, 1754 ) and Fausto D´Elhuyar (Logroño, 1755) who discovered a yellow spicy/bitter tasting salt from the reaction of ammonium molybdate with phosphoric acid which is now known as ammonium 12-phosphomolybdate, (NH […]
