Spallation is a type of nuclear reaction in which the interacting nuclei disintegrate into a large number of protons, neutrons and other light particles, rather than exchanging nucleons between them. It is thought that most of the nuclei of light elements, such as boron, are made in this way. Spallation reactions of this type are […]
Conspiracy theories are one of the mechanisms to manipulate information intentionally. They present fact-resistant theories and tell unsubstantiated stories that try to explain reality in an alternative way with false information. According to the media context of the second decade of the 21st century, these theories are more visible and have greater reach due to […]
A team of scientists at two British universities, Bath and Bristol, have developed neuron-like chips that could revert the neurological damage caused by neurodegenerative diseases like Alzheimer’s. These chips do not only resemble neuronal function but are also very efficient and low energy consuming. Can we ask for more? Obviously, when I say chip, I […]
Many amphibians have that certain glow Many amphibians, mostly salamanders and frogs, fluoresce under certain light conditions. Researchers tested 32 amphibian species using blue light and found that all glowed green or yellow, but they haven’t yet figured out why this occurs. New Scientist Massive blast ever observed in faraway galaxy observed Astronomers have detected […]
There are chemical compounds, called isomers, that have the same molecular formulae but different molecular structures or different arrangements of atoms in space. In constitutional isomerism the molecules have different molecular structures: i.e., they may be different types of compound, or they may simply differ in the position of the functional group in the molecule […]
Chronic pain is one of the most common problems of advanced age. Even though the combination of physical therapy and analgesics such as nonsteroidal anti-inflammatory drugs is effective in chronic pain treatments, it only confers short-term benefits. On the other hand, it could be quite expensive and may have significant adverse side effects. Effective, lasting […]
Many people think of their brain as a computer full of microchips and wires, as a storehouse full of memories and learned things, as a clock with millions of mechanisms intimately intertwined with each other, so it is incredible to think that someone can live with much less than that, with only one brain hemisphere […]
Earth may have formed in just 5M years The Earth formed in only about 5 million years, a much shorter amount of time than previously thought. Researchers developed this new timeline based on a study of iron isotopes collected from meteorites. ScienceAlert These fish can pause cell, organ growth as embryos African turquoise killifish can […]

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. Imagine that we have a conductor or a semiconductor through which a current is flowing. Then we apply a strong transverse magnetic field. As a result, we can […]
I n a 2017 interview, the famous actress Kate Walsh – whom you may know from the TV show Grey’s anatomy – reported the following: “ I started having more cognitive difficulties. It felt like aphasia [language problems] , but it was not just not being able to find words; I would lose my train […]
