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 […]
Every day, each person on the planet consumes 2868 Kcal, 19% of those calories come from the world’s most important crop, rice, closely followed by wheat (F.A.O). In some Asian countries such as Bangladesh, Indonesia or Philippines rice represents up to 70% of the daily caloric intake (Figure 1). Many research efforts have been done […]

Dark matter detected as it coasts through galaxy collisions Dark matter appears to drift straight through galactic collisions, barely interacting with anything, including other dark matter, according to scientists who detected the mysterious stuff by the way it bends nearby light paths. Researchers used visible light spied by the Hubble Space Telescope and X-rays by […]
Last Friday I was, as is always the case listening to an enthusiastic talk given by one of the PhD students from my department. As part of her PhD work, she is trying to understand why periodontitis, an inflammatory disease where gums get swollen as a consequence of bacterial infection, is essentially painless. This is […]
Most leaves are various shades of green. This is due to the chlorophylls. The name chlorophyll comes from the Greek words chloros (green) and phyllon (leaf). There are six types of chlorophylls in plants. The two main chlorophylls are chlorophyll a and chlorophyll b. Chlorophyll a absorbs purple and orange light the most. Chlorophyll b […]
