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 […]

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 […]

Consider a country with two left-wing and two right-wing parties. In each side of the political spectrum one of the parties is a radical and the other is a moderate. Consider also that the moderates attract more voters than the radicals. To fix ideas consider that the percentage of supporters are 15, 33, 30 and […]
