RINGED NEPTUNE CAPTURED BY JAMES WEBB TELESCOPE

The recently launched super space telescope James Webb has returned spectacular new imagery of Neptune. The observatory's infrared instruments highlight features not seen in such detail since the Voyager 2 probe flew past the planet in 1989. These include the rings and dust bands that encircle the ice giant. Scientists are also intrigued by the different cloud structures, which should tell them something novel about the workings of Neptune's atmosphere. Beyond the planet itself are seven of the giant's 14 moons, the most significant of which is Triton. ...

WHAT IS A TEMPORAL CRYSTAL AND HOW IT CHANGES OUR UNDERSTANDING OF THE LAWS OF PHYSICS SCIENCE

At the end of July, Google announced that its engineers managed to create a new state of matter inside a quantum computer - the so-called time crystal (or temporal crystal), the very existence of which seems to defy the fundamental laws of physics known to us ... Time crystals are set to play a pivotal role in building quantum computers so fast and powerful that they can solve tasks in minutes that would take millennia for today's processors…

JAMES WEBB SPACE TELESCOPE: SEARCHING FOR SIGNS OF LIFE IN SPACE

"Where did the universe come from? How do stars and planets form? And ultimately, this question is about is there life out there." These are the questions that Cardiff University physics and astronomy lecturer Dr Sarkar is hoping Webb will help answer. Together with Dr Nikku Madhusudhan, of Cambridge University, Dr Sarkar will analyse the atmosphere of the potentially life supporting planet K2-18b - 124 light-years away from Earth...

ELECTRONIC WHIRLPOOLS: SCIENTISTS MADE ELECTRICITY BEHAVE LIKE WATER

Researchers from the Massachusetts Institute of Technology (Massachusetts Institute of Technology, MIT) for the first time in history managed to observe the formation of electronic whirlpools. Such bizarre behavior of electrons occurs when an electric current begins to behave like a fluid flow, obeying some of the known laws of hydrodynamics. And, it is likely that in the future, scientists will be able to use all this to create a new type of high-speed and highly efficient electronics…

A 40-CHANNEL OPTICAL COMMUNICATION LINE WILL ALLOW DATA TO BE TRANSFERRED WITHIN A SINGLE CHIP OR COMPUTER AT A SPEED OF 400 GB PER SECOND

Scientists at the University of Central Florida have developed and demonstrated a silicon optical link that combines two different multiplexing technologies. This, in turn, makes it possible to organize 40 independent channels in one beam of light, each of which can carry out independent data transmission, and the total transmission rate along this line is 400 GB per second…

NEW DATA TRANSFER RECORD BREAKS 1 PETABIT PER SECOND

A group of researchers from Japan has become the owner of a new data transfer record, which amounted to 1.02 petabits per second. What's more, this record was achieved with fiber optic cables that are fully compatible with existing communications infrastructure. For reference, 1 petabit is equal to one million gigabits, which means that the transfer speed achieved is 100,000 times faster than the fastest Internet access available to ordinary consumers…

A UNIQUE QUANTUM SENSOR HAS BEEN CREATED THAT CAN SIMULTANEOUSLY MEASURE THE INTENSITY, POLARIZATION AND WAVELENGTH OF LIGHT

A team of researchers from Yale University and the University of Texas at Dallas have created a tiny quantum optical sensor that is about one-thousandth the size of a human hair. But, despite such a small size, this sensor has the widest possibilities, using the quantum properties of electrons, it is able to simultaneously measure the intensity, polarization and wavelength of light. The creation of such a universal sensor will allow in the future to make significant breakthroughs in...

THE WORLD'S MOST POWERFUL X-RAY LASER BECAME ABLE TO GENERATE A MILLION PULSES PER SECOND

The world's most powerful X-ray laser, LCLS (Linac Coherent Light Source), which has gone through a large-scale upgrade and modernization of the LCLS-II, is almost back in operation and will soon be ready to work for the benefit of modern science. After being upgraded, temperatures inside this huge facility are lower than those in outer space, which allows electrons to be accelerated to speeds very close to the speed of light, and to generate a million very bright x-ray flashes in one second...

MOST IS A SYSTEM CAPABLE OF DIRECTLY ABSORBING SOLAR ENERGY, ACCUMULATING AND STORING IT FOR MANY YEARS

Back in 2017, a group of researchers from the Chalmers University of Technology, Sweden, developed a rather interesting energy system that can absorb solar energy without intermediate transformations, store it in liquid form for many years, and return it as needed. Since then, researchers have been developing ultra-thin thermoelectric generators, the combination of which with the aforementioned storage system will make it possible to create self-charging electronic devices, solar power plants of a new type, etc...

CARBON NANOTUBES ARE THE BASIS OF A NEW BULLETPROOF MATERIAL SUPERIOR IN PARAMETERS TO KEVLAR AND EVERYTHING

Very often, weight is the price that has to pay for an increase in the efficiency of bulletproof materials used to create individual means of protection. But researchers from the University of Wisconsin in Madison managed to create a new type of ultralight material, which is a "mat" woven from nanofibers. Moreover, during the operation of this material, certain chemical processes are involved, which makes it more efficient than traditional kevlar and steel.

THE FIRST OF ITS KIND TOPOLOGICAL ACOUSTIC TRANSISTOR IS CREATED

There are so-called topological materials in the world, inside which electrons move only along the surface or along the edges of the material with practically no loss of energy. These materials are considered extremely promising for the creation of next-generation electronics, highly efficient and small-sized. But while there is still one problem that scientists have not been able to overcome, transistors based on topological materials cannot be turned on or off without dissipating electrons, and therefore without energy loss.
