The possibility of time travel has excited scientists for hundreds of years, inspiring countless books and films. The ability to move not only in space, but also into the past or the future would open up many possibilities for humanity. But is time travel theoretically possible?
Krasnoyarsk scientists have obtained new promising thin films made of oxygen, copper and titanium nitride. Their electrical resistance is a thousand times less than that of ordinary titanium nitride. Based on the obtained material, physicists have discovered new properties of copper that allow it to accumulate on the surface of films and make phase transitions. The results obtained can become a technological breakthrough in the development of resistors and transistors of a new generation.
In addition to the basic well—known states of matter — solid, liquid, gas and plasma - many other, much more exotic states can be created in the laboratory.
The technology of fixing the neutrino flux coming from a nuclear reactor was proposed by MEPhI scientists 50 years ago. Modern developments are being carried out on elastic coherent scattering discovered three years ago – the interaction of neutrinos with energy conservation with all nucleons at once.
Materials that change their properties in response to certain stimuli can occupy a valuable niche in many fields, from robotics to medicine and modern aircraft. A new example of such a shape-shifting technology was presented in the form of an imitation of ancient chain mail armor, which allows you to quickly switch from a flexible version to a rigid one due to the features of the material.
Plants need water no less than animals. But exactly how they pass it through their tissues remained a mystery, which was solved only recently.
Skoltech researchers and their colleagues from the Royal Institute of Technology (KTH) and Uppsala University (Sweden) predicted the presence of antichiral ferromagnetism in a certain class of magnetic crystals – an unusual property that can give rise to research on a number of new effects associated with magnetism.
Scientists have deduced the dependence: the higher the sea level, the lower the volcanic activity on Earth.
There is a replenishment in the zoo of elementary particles. The LHCb collaboration (CERN, the European Organization for Nuclear Research), which includes the G. I. Budker Institute of Nuclear Physics SB RAS (INP SB RAS), Novosibirsk State University (NSU), the A.I. Alikhanov Institute of Theoretical and Experimental Physics, the Kurchatov Institute (ITEF), etc., announced the opening of a new particle – the exotic tetraquark Tss+. The particle stands out strongly among its fellows and represents a new form of matter.
Astrophysicists have discovered light coming from the back of a black hole. This discovery confirmed hypotheses about how these colossal objects distort the streams of light.
