Author: Meilani Wibowo obtained her master’s degree at the University of Valencia, Spain. Currently she is a Ph.D. student (ITN-EJC TCCM) at the University of Groningen, the Netherlands, where she works on the improvement of organic photovoltaic devices. Solar energy as one of the alternative and sustainable energy sources has a potential to replace fossil […]
This year the Nobel Prize in Chemistry has been awarded to Jean-Pierre Sauvage, Fraser Stoddart and Ben Feringa “for the design and synthesis of molecular machines” . These devices, often described as the tiniest “Lego” , a re indeed so small that is difficult to grasp their size used as we are to the macroscopic […]
Author: Tommaso Francese is a Ph.D. student (ITN-EJD-TCCM) at Universitat de Barcelona Every year the amount of data produced is of the order of magnitude of the Avogadro’s constant, thus 6.028×10 23 . Let’s say that it is more or less the quantity of hydrogen atoms contained in 1 gram. This trend is supposed to […]

Busy cells on the move in babies’ brains observed Neurons move through babies’ brains to where they are needed most in the first few months after birth, and these movements have now been seen by researchers. Researchers say the cells are most active in newborns, with activity slowing when the babies are about 5 months […]
Autism spectrum disorders are a group of developmental disorders that cause lifelong disabilities. They affect people’s ability to communicate, to interact with others and to understand social cues. Affected persons have difficulties recognizing body language, making eye contact, and understand other people’s emotions, symptoms that hurt the individual’s ability to function socially, at school or […]
Running is an activity that humans have held for millennia. It has been a tool, a hobby or a fashion rose by needs, crisis, culture or marketing campaigns. Today, in a busy and sedentary society aware that to maintain health it is necessary to move the ass, running has become again a major way of […]
In the previous entry we saw how the so called ‘Representational Theory of Measurement’ appeared to solve one of the deepest problems in the empiricist account of scientific knowledge: how to justify the use of numbers in science (and the calculations that used them), taking into account that all knowledge was supposed to be grounded […]

Bumblebees’ emotional buzz charted Happy bumblebees are productive bumblebees, according to a study published in Science that charted how the insects’ changing moods affected their decision-making behavior. The findings are the first clues that primitive emotional states exist in bees. ScienceNews Astronomers see spiral arms surrounding new star for first time Spiral arms like those […]
The purpose of this note is to introduce the reader to the notion of Lipschitz structure and its potential applications to the spin geometry required to globally formulate string theory and supergravity on a differentiable manifold. Spinors are a crucial ingredient in the global formulation of string/M-Theory and its low energy limit supergravity, since these […]
Cataglyphis , the desert ant, is a genus in the subamily Formicinae. The most famous species is C. bicolor , the Sahara Desert ant. There, the midday sun is so hot that even the permanent residents, sand lizards, insects and a few birds, have to take shelter. But this is when, for not much than […]
