Spintronic devices are based on the inherent spin magnetic moment of the electron, the same way electronic ones are on just its charge, to store and process information. These devices should, in theory, operate faster and at lower temperatures than their current electronic-only counterparts because an electron’s spin can be flipped much quicker than its […]
Fermentation is a form of anaerobic respiration occurring in certain microorganisms, like yeasts. Many processes arising in diverse contexts can be classified as fermentation processes, such as manufacturing of some food products (baking, wine and beer industries are based on them) and of some industrial and pharmaceutical chemicals. Alcoholic fermentation comprises a series of biochemical […]

An Earth-like planet named GJ 1252b orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets. Because M-dwarfs are so ubiquitous, this discovery means a large number of […]
Mutation found to affect circadian rhythm Researchers have discovered genetic mutations in hamsters that speed up the animals’ internal clock and affect circadian rhythms. “We suspect this might be relevant in understanding the effects of jet lag and shift work,” said neurobiologist Eric Bittman, a co-author of the study. Full Story: ScienceDaily Viruses found active […]
The band theory of metals has been experimentally tested many times and is now the accepted model of the behaviour of conductors and insulators. Electrical resistance is due to collisions of the electrons (whether treated as particles or waves) with impurities, imperfections, and especially the lattice vibrations of the metal crystal. The lattice vibrations of […]
Discarded electronic devices, such as cell phones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers have created disposable papertronics, a prototype circuit board that is made of a sheet of […]
In 1906, Alois Alzheimer, a psychiatrist and neuroanatomist, reported “a peculiar severe disease process of the cerebral cortex” to a gathering of psychiatrists in Tübingen, Germany. The case was a 50-year-old woman who suffered from memory loss, delusions, hallucinations, aggression and confusion – all of which worsened until her untimely death five years later. In […]
Black hole collision behaves as Einstein predicted Scientists studying the collision of two huge black holes observed massive gravitational waves and a phenomenon known as precession, which resembles the wobbling motion of a spinning top. Albert Einstein’s theory of general relativity predicted a century ago that precession would occur in massive objects — but this […]
There are instances in which you would intentionally deliver nanoparticles to animals (humans included). Contrast agents for medical diagnosis or therapeutic ones for medical treatments are two examples. It is also the case with plants, as some fertilizers take the form of nanoparticles. Unintentional exposure of animals or plants to nanoparticles is also possible: environmental […]
A few years ago, the chess website Chess.com temporarily banned US grandmaster Hans Niemann for playing chess moves online that the site suspected had been suggested to him by a computer program. It had reportedly previously banned his mentor Maxim Dlugy. And at the Sinquefield Cup earlier this month, world champion Magnus Carlsen resigned without […]
