Let ‘s continue with the story of the development of the loophole-free Bell experiment. As we discussed in the first post, it is possible to prove that the universe is either non-real, meaning that the outcomes of some experiments can only be predicted statistically, or it is non-local, meaning that there are signals that propagate […]
Today February 29th is celebrated worldwide the Rare Disease Day. This year’ slogan is “Join us in making the voice of rare diseases heard”. So this is my small contribution to such campaign, essential nowadays to increase support to all the people suffering those disorders and to their families. Because rare is the disorder but […]

Scientists find clues to suggest new type of neutrino Hints of the existence of an elusive sterile neutrino have been detected in the Daya Bay nuclear reactor facility near Hong Kong. This would be the first discovery of a particle which cannot be accommodated in the framework of the so-called standard model. Science News Quantum […]
They say that Information is power. Probably because having the knowledge, when the data are correct, it is essential to anticipate the right move that will lead to success. Today, several decades into the information age seems to be no doubt about that. Regardless, in matters affecting our health we find a tangible example of […]
The most prevalent use today of semiconductors is forming them into transistors, the basic electronic building blocks of all “solid-state electronics” and computer microchips. Semiconductors are the most important materials in the burgeoning revolution in computers and other electronic devices today. Such applications also arose, beginning in the 1930s, from the quantum mechanics of the […]
In multicellular organisms, embryonic stem cells develop into any of the different cell types that will form the adult, and along the development, they silence or activate different parts of the genome, giving rise to distinct cell identities, which are maintained throughout adult life by epigenetic mechanisms. A similar procedure may be at work at […]
One hears blue blood and immediately thinks about royal family members. Some biologists, though, immediately will think about Limulus polyphemus , a marine animal commonly known as the horseshoe crab. Why? Because, very surprisingly, this arthropod actually has true blue blood! Human blood is red because of the hemoglobin inside our red blood cells, which […]

Disks can store information for billions of years A new five-dimensional data storage method has been developed that researchers say can last up to 13.8 billion years, withstand extreme heat and hold all sorts of information. The data are encoded into minuscule nanostructures in small glass discs. The Verge New carbon structure can hold liquids […]
The interactions between moving charges and magnetic fields can be quite complicated; more if we consider the quantum effects. One example is the collection of Hall effects. There are analogues of these effects for spin and the detection of the most sophisticated one in graphene, where, at least, it should not be strong, is something […]
All we know about fire under Earth´s gravity must be questioned in microgravity. In fact, most of the well-known characteristics of fire behavior are driven by the effects of gravity. That´s why the science of combustion in low-gravity environments is an important field of knowledge for NASA studies when evaluating spacecraft safety. And, contrary to […]
