Closer to understanding what dark matter is?

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

What are the 5 most radioactive places on Earth?

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

Perovskite: the stuff the next HD could be made of

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

This was the first nuclear fission reactor in history

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

Magnetic Hills: Hills that appear to slope but not

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

An object has been cooled below the quantum limit

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

Do we already know why meteorites make noise when crossing the sky?

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

How is it possible for a thermos to keep hot liquids warm?

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

Why can your coffee spoon be hotter than coffee?

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

Light makes you weigh more on a scale (if very accurate)

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

Fluid is created that, when pushed, accelerates towards you

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

Neural functions are simulated with this quantum transistor

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

World’s Smallest Neutrino Detector Confirms Interaction

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 promises as much as the LHC

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

Erbium-doped crystal: the perfect material for a quantum internet

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
