Superconductivity is a physical phenomenon in which some materials exhibit zero electrical resistance when cooled down below a certain critical temperature. As surprising as it can be, the critical temperature of these materials can be modified by reducing the sample size to about a million times the size of the objects we are used to […]
Dip. Di Chemica, Università di Torino, via P. Giuria 7, 10125, Torino, Italy * adrian.matencioduran@unito.it The last articles of one of us (Matencio) [1,2,3,4] were about the different uses of a complexing agent called cyclodextrin (CD), a torus-shaped oligosaccharide made up of α-(1,4) linked glucose units, the most common CDs being α, β and γ-CD […]
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 […]
Species distribution models (SDM) are computer algorithms that relate species distribution, occurrence or abundance, with information on environmental conditions and spatial characteristics of locations where the species has been, or is suspected to be, found. These models can be used to predict or to have a better understanding of the species distribution, and are widely […]

Usually, optical activity is understood as the ability some substances have to change the handedness of polarized light when it goes through them. Molecules that show optical activity have no plane of symmetry. The commonest case of this is in organic compounds in which a carbon atom is linked to four different groups. An atom […]
We all know exercise is important to be healthy, every doctor in the world would tell you so. Now, new research in the journal Nature Communications , we also know who to thank for. Sestrins, a protein family has been linked to the health benefits of exercise. Sestrins improve physical performance It was previously known […]
An interesting question is whether the brains of gay and straight people are the same or different. One study found that they are slightly different and that the brains of gay men, in the aspects analyzed, are more similar to those of heterosexual women. This would support the idea that sexual orientation is a biological […]
A quantum dot (QD) is a nanometric crystalline structure of semiconductor materials. In a QD 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 […]
Believe it to not, little worms (C.elegans) are an useful tool for researchers studying aging. Specially, the genetics of aging. A recently released article in Cell Reports shows that gene modification in two specific cellular pathways drives 500% life extension in worms. Why worms? Worms are the ideal research subject for aging and genetics because […]
Why do some songs succeed and others fail? Some researchers believe that a key factor is their involvement with our personal universe: if they foster feelings of social connection, they get the approval of the public; if not, they are ignored and forgotten. If that were true, songs that fit that personal pattern should fall […]
