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 […]
Ideology is a concept that has always made me feel a bit perplexed. I have thought a lot about this question in the last weeks, when comparing the reactions and suggestions of different people about the shocking events the world is now involved into. Why do people have so much disparate ideas about the facts […]
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 […]
Array of facial expressions detected in mice Subtle facial movements indicating a number of emotions have been detected in mice by machine learning tools that may help researchers learn more about how animals convey emotions. Researchers used high-speed cameras to capture the mice’s expressions as they were given experiences meant to spark emotions such as […]
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 […]
When we perform Google searches, most of us assume that we all see the same results and that the first ones to appear are the most relevant from links to other pages. However, this is not the case. Since 2009, Google’s algorithm has provided results that are better for you. This personalization of pre-selected and […]
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 […]
Radiation tsunamis may be coming from quasars Quasars may be releasing tsunami-like bursts of radiation that can push material from their home galaxies outward and may inhibit star formation, according to findings in six studies published in The Astrophysical Journal Supplement Series. “The amount of mechanical energy that these outflows carry is up to several […]

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 […]
