The Large Hadron Collider (LHC), which has given us so many joys (such as the detection of the Higgs boson) should work until 2035, however the international community of physicists has been working for years on the next great machine that will unravel the nature of the smallest. That machine could be the Compact Linear … Read more
Four fundamental forces have been described in the universe: strong nuclear, weak nuclear, electromagnetic and gravitational. However, a couple of months ago indications of a fifth force could have been detected. The finding comes from an analysis carried out by theoretical physicists at the University of California at Irvine (UCI) that reached in mid-2015 to … Read more
We are a set of processes that is believed to be a unit encompassed or held together by a kind of I. But it’s not like that. No matter how much we use a scanning electron microscope, a mass spectrometer, an X-ray diffractor or an electron microprobe, we will not find anything that can be … Read more
Ionizing radiation is measured with Geiger counters, and is capable of stripping electrons from atoms. The absorbed radiation dose is measured in units called sieverts, equivalent to one joule per kilogram. A dose of 6 sieverts kills 90% of people within 14 days . Below 0.25 sievert it is considered that there are no consequences. … Read more
A new material based on perovskite (a relatively rare mineral) whose magnetic order can be quickly changed without overheating could form the hard drives of the future, replacing current silicon systems. This development, which would lead to the creation of higher density, faster and more efficient hard drives, has been carried out by researchers from … Read more
The first chain reaction controlled by nuclear fission took place on December 2, 74 years ago, at the University of Chicago, specifically, the Chicago Pile-1 (CP-1) was built on a tennis court, under from the stands of an abandoned stadium. The place where the first nuclear reaction occurred was declared a National Historic Landmark in … Read more
A measured value of 80370 +/- 19 MeV, which is consistent with the Standard Model prediction , is what the base of the W boson measures . A value that has been obtained thanks to measurements made with the Large Hadron Collider (LHC) installed at CERN. Such a precise measurement of the mass of the … Read more
The wide world is so strange that it can even contain mountains that run backwards or roads that seem to trace an upward slope that is actually downward. Just throw a ball to see it . They are called magnetic hills, and they are in many countries of the world . What is a magnetic … Read more
A team of physicists from the National Institute of Standards and Technology (NIST) in the United States has managed to cool an object below the temperature limit described by quantum physics, that is, to less than a fifth of a quantum . These temperatures so close to absolute zero (the lowest possible temperature in the … Read more
Sound travels much slower than light, so the sounds should arrive several minutes after the meteor rubbed against the atmosphere. However, on many occasions, when we watch a meteor soar through the sky, we can hear sizzling, cracking and hissing sounds as it descends and simultaneously . A new study offers an explanation for this … Read more
A paper clip is one of the seemingly most insignificant everyday objects. It is just a very small piece of metal that is used to capture leaves and little else. However, a paper clip is an almost legendary object if we examine it a little more closely . Because a paper clip is actually made … Read more
The magic of a thermos, capable of keeping a hot liquid warm for longer than in its natural state, is even more extraordinary when we consider that the same object, the thermos, is also capable of keeping cold liquids cold. But how can a thermos have the ability to do two seemingly diametrical things? Air … Read more
Normally, when we stir our hot coffee, the spoon is cold or slightly warm, but never as hot as the coffee itself. However, perhaps on occasion, this will not happen like this. How can a teaspoon get so hot with regular coffee? House of lineage If this phenomenon happens to you, surely you will be … Read more
The quick answer to the fact that if two cups of sugar of the same volume fit in another cup also of the same volume but full of water is yes, but how is it possible? Originally, we have filled a cup of sugar, the logical thing would be to suppose that we cannot fill … Read more
Imagine an ice box that will travel to the International Space Station (ISS). A box inside which a series of lasers, a vacuum chamber and an electromagnetic "knife" want to cancel out the energy of the gas particles, slowing them down. And thus be able to create the coldest point in the universe . Zero … Read more
Everything we see around us is actually seen by a process in which photons bounce off the surface of things and subsequently hit our eyes. Through a chemical process, we transform that signal into images. That means that, well, things are impacted by light, and so are we, and that rebound, although tiny, "pushes" things … Read more
Isaac Newton’s Second Law of Motion postulates a force equal to the mass of an object multiplied by its acceleration. If we push a thing, that thing moves away from us. However, physicists at Washington State University (WSU) have created a mass negative liquid that does just the opposite: it comes close to you when … Read more
Of all the matter in the visible universe, only 4% is normal matter , like the matter from which all things we know are made. 23% is made of dark (invisible) matter, which physicists suspect exists but do not know what it is. The remaining 73%, that is, almost all the matter in the universe, … Read more
It is able to see light information, count and store in its own structure. These are the neural functions that this transistor based on quantum dots can simulate, as revealed in an article published in the journal Nano Letters . The transistor has micrometer and nanometer parts. Epitaxial growth The transistor has been conceived thanks … Read more
The freezing of water in a strange, dense form called Ice VII has been captured for the first time by Stanford researchers. It is a form that does not occur naturally on Earth , but on other planets. Ice VII The phase change (from liquid to ice) lasted only 6,000 millionths of a second, or … Read more
Theoretically, it has been argued that neutrinos (particles with no charge and hardly any mass) were capable of interacting with the entire nucleus of an atom (and not just with neutrons and protons separately). Now the world’s smallest neutrino detector has identified this interaction . A 40-year theory An international group of researchers has confirmed … Read more
The European Spallation Neutron Source (ESS) is a great linear particle accelerator that will allow us to observe the interior of the materials that make up our world in order to be able to study how their atoms move and interact inside, promising as many discoveries as the CERN’s Large Hadron Collider (LHC). ESS In … Read more
Are the physical laws the same in the hot, dense conditions in the atmosphere of a dying white dwarf star as they are here on Earth? That is what a new study led by researchers at the University of Leicester is now trying to elucidate. These stars have masses around half the Sun compressed into … Read more
Researchers at the Australian National University (ANU), led by Associate Professor Matthew Sellars , have shown that an erbium-enhanced crystal is specially adapted to enable a global telecommunications network that takes advantage of the strange properties of quantum mechanics. Erbium The work , published in Nature Physics , demonstrates how to dramatically improve the storage … Read more
