The concept of moduli space is of utmost relevance in theoretical physics and mathematics, especially in geometry, topology and string theory. A moduli space is, roughly speaking, a space that classifies a given class of objects modulo an equivalence relation # which identifies the objects in that we want to consider as equivalent or, more […]
Accepting asylum-seekers, migrants boosts nations’ economies An influx of migrants and asylum-seekers is beneficial to a country’s economy within five years. Researchers based their findings on 30 years’ worth of data collected from 15 Western European countries. Nature Shallow hydrothermal vents discovered near Azores Hydrothermal vents found off the Azores are not as deep or […]
Since the discovery that graphene, the two dimensional carbon allotrope, can be isolated and incorporated into electronic devices intense research efforts have been triggered. Driving forces usually mentioned behind the experimental and theoretical studies of graphene are the exceptional electronic properties, in particular the high electron mobilities, the long spin coherence lengths and the possibility […]
While I was at school it was almost a dogma that you’d not get a neuron more than those you were born with. Later, at university we learned that actually there was a region in the human brain, namely the hippocampus (key region for memory formation) where there was indeed adult neurogenesis, that is, formation […]
Ravallion (2018) questions the thesis that globalization has been a major driving force of inequality. While this is the conclusion of two recently published books (Bourguignon, 2016 and Milanovic, 2016 ), Ravallion argues that their interpretation of the data is not well supported and that is even contradicted by the economic research. Here is a […]
Spiders spin extremely thin sheets to help them move through air Contrary to the belief that spiders “fly” with the help of just a couple of fibers, a new study shows they make triangular sheets out of ballooning fibers that are almost invisible. The sheets are largely made from silk only 200 nanometers thick. New […]

The electronic wave function of an n-electron molecule depends on 3n spatial and n spin coordinates. In a sense, the wave function of a many-electron molecule contains more information than is needed and is lacking in direct physical significance. This has prompted the search for methods that involve fewer variables than the wave function and […]
Lipinski’s “rule of five”, 1 very well known by medicinal chemists, has been defined as a set of rules, based on the number 5 -hence its name-, to evaluate the “drug-likeness” of a given molecule. The rules are: – The molecule should have no more than 5 H-bond donors and 10 H-bond acceptors (i.e. N […]
The most effective interventions in people with autism are based on a personal work by specialized professionals and these therapies, when well designed and well done, achieve a constant improvement in different areas such as social communication, the presence of stereotypes and other atypical behaviors characteristic of autism. However, person-to-person therapies are by their very […]
Cavers find new connections in massive Sistema Huautla Mexico’s Sistema Huautla, one of the world’s deepest cave systems, is larger than previously thought. A group of cavers and researchers found new connections while trapped by flooding inside Sistema Huautla. National Geographic Number of new flu strains found in dogs in China Three hybrid canine flu […]
