An international team of physicists has succeeded in creating a two-dimensional superhard body. It has the properties of both a solid and a superfluid
Analyzing data from the LHCb detector installed at the Large Hadron Collider, scientists have found reliable evidence for the existence of a unique particle - a doubly overtly charmed tetraquark. And no matter how outlandish its name sounds for a person who is not familiar with the Standard Model, it gives physicists even more strange information: it seems that modern scientific ideas about the structure of the world will again have to be pretty shaken up
New work by Russian researchers indicates that the Universe has not always been expanding - and will contract again in the foreseeable future. Moreover, it is doubtful that humans will be able to survive the cycle of its compression. But the good news is that the universe itself is no longer in danger of heat death. Understanding the details
The most powerful nuclear power plant in Russia in terms of installed capacity is the Leningrad Nuclear Power Plant. Its electric capacity is 4200 MW
Scientists have discovered a material that can become an insulator, then a conductor - depending on the applied pressure
New motion compensation technology helped cool LIGO mirrors to only billionths of a degree
In a heated and oiled frying pan, a drop of water quickly boils and moves from side to side thanks to the jet draft of steam
The ring of the "lunar hadron collider" will be able to sweep the satellite along the equator and collide protons with energies thousands of times greater than the famous LHC
Laboratory experiments fully confirmed theoretical calculations that linked the appearance of auroras with the acceleration of electrons by Alfvén waves in plasma
A new layered modification of silicon can find application in promising types of electronics, batteries, solar cells
On Friday, May 28, an experiment was held at the EAST tokamak, the results of which are extremely important for the world thermonuclear energy. The "Chinese man-made sun" heated the plasma to a temperature almost seven times higher than in the bowels of a natural luminary, and held it for more than one and a half minutes
New barium sulphate dye reflects visible and infrared waves, keeping temperatures below ambient
European scientists have demonstrated a prototype of a system that reconstructs the "structure" of a diffuse barrier and displays an image on the other side of it
The question of developing ways to store electricity in the 21st century has become incredibly acute - scientists from all over the world are racking their brains over how to make batteries more capacious. The US Army Research Laboratory has made strides in creating the finest anti-ferroelectric lead hafnate films. This compound, which is difficult to obtain, has great potential for use in batteries and electric valves
An international team of scientists has perfected the ptychography method to get close to the physical limitations of its resolution. In the picture they received, individual atoms are visible, and few distortions are caused by their thermal vibrations
The Muon g-2 experiment measured the anomalous magnetic moment of muons, confirming that it does not match the calculated value. This deviation indicates the existence of particles or interactions unknown in the Standard Model of quantum mechanics
A young scientist from a Dutch university has created a neural network algorithm that allows you to radically accelerate the simulation of plasma behavior in a fusion reactor
Michio Kaku is one of those popularizers of science who have been actively working in it for more than a dozen years. In a new interview, timed to coincide with the release of the new book, he told how and why it is necessary to explain complex physical concepts to the broad masses, and also answered many questions "about life, the Universe and in general."
The more we learned, the more questions we had. And, perhaps, the main one: how to find a general explanation for all phenomena? To answer it, you need to create a Theory of Everything
On February 28, 2020, the physicist Freeman Dyson, whom most of us know from the "Dyson sphere", died - the concept of a huge sphere that fully uses the energy of a star and gives room for life to quintillion people at once. However, in fact, this is not exactly his idea, but Dyson's contribution to other branches of science and technology was much more important. So much so that all Western media trying to write about his death faced a serious problem: a great scientist died, but because of "heretical" views, even in the necro
The results of ultra-precise measurements of the energy levels of positronium particles did not coincide with the results of ultra-precise calculations, and it is not yet clear what this discrepancy may be related to
Scientists were the first to reproduce in reality the paradox of Wigner's friend. As a result, physicists found out that quantum phenomena are subjective: each observer can have his own alternative facts about them, and all of them will be true
A team of scientists from different countries has built the first of its kind quantum heat engine, the performance of which exceeded the maximum efficiency of a classical engine
Wormholes may exist and be traversable, but they are unlikely to be used as shortcuts to travel through the universe, according to new research
For more than a decade, physicists working on all kinds of particle accelerators and other experimental facilities have been trying in vain to detect dark matter particles. Now, it looks like scientists have found a way to help them in this difficult task
March 15, National Accelerator Laboratory. Enrico Fermi has officially announced a new project that will help conduct cutting-edge physics experiments for decades
Researchers in Singapore and Australia have developed a photonic quantum information processor capable of generating 16 likely future scenarios simultaneously
American physicists have simulated black holes with extreme parameters and found them to have unique characteristics. They are also called "hair" because they can distinguish such astronomical objects with the same mass, spin and charge. And this runs counter to one of the direct consequences of General Relativity - the no hair theorem
The matter is small: you need to get close to the event horizon itself and generate a magnetic field, which will intersect in a certain way with the magnetic field of the black hole
Coronary multichannel polarimeter helped physicists to do this
If the mouth of the interdimensional tunnel is large enough, then a person can withstand the effects of tidal forces
The constant describing the interaction of matter with electromagnetic radiation may not turn out to be a constant at all
The fifth power unit of the Fuqing NPP was connected to the power grid - this is a full-fledged commissioning of the first Chinese nuclear reactor of generation III + Hualong One, entirely of its own design. According to local experts, this significant event gives hope for the success of this type of reactor not only on the domestic but also on the international market
American physicists have received new data on the internal structure of the proton, which run counter to the results of experiments carried out in the early 1990s. They give a chance to the already "set aside" theories explaining the asymmetry of this particle to become relevant again
Two researchers from the University of North Carolina (NC State University) have created a theory of space-time based on modern mathematical constructions. According to them, it explains the structure of the world better than the theory of relativity, proven by hundreds of years of experiments and objections
Scientists working on the ATLAS experiment at CERN may have discovered one of the rarest phenomena predicted by the Standard Model of particle physics
These are signs of the so-called New Physics - a comprehensive theory that should describe our Universe as fully as possible
One of the detectors of the Large Hadron Collider has discovered a new particle, consisting of four charmed quarks. Physicists believe that this is the first representative of an undescribed class of particles

A team of theoretical physicists from Uppsala University in Sweden has developed a new model of the universe that can solve the mystery of dark energy, which many scientists believe is responsible for the expansion of space
