Taken together, this new material holds great promise for applications ranging from creating robots with more power without using additional energy to new helmets and protective materials that can dissipate energy much faster, the authors of the paper claim.

Alfred Crosby, professor of polymer science and engineering at UMass Amherst and senior author of the paper says, “Imagine a super-rubber. When you stretch it to a certain limit, you activate the extra energy stored in the material. When you let go of that rubber band, it travels a whole mile.” Their material will be made from a new metamaterial – a substance designed to have properties not found in naturally occurring materials – that combines an elastic, rubber-like substance with tiny magnets embedded in it. This new “elastomagnetic” material takes advantage of the laws of physics to greatly increase the amount of energy the material can release or absorb.

Thus, science knows that another aggregate state of matter is plasma. In this case, it is quite possible to see it with the eyes. Things are much more complicated with the other states.

For example, there is a variant in which the bonds of molecules in matter are in an unusual position, which makes their existence real only “on paper”. Such, for example, include “Bose-Einstein condensate” and “time crystals”.

According to scientists, the latter are characterized by the constant repetitive motion of molecules. The surprising thing about them is that they don’t spend any energy for this.

In turn, the substance in the “Bose-Einstein condensate” state describes boson particles of high density and low temperature.

This is a new version of the atomic clock. It is claimed that it should be more accurate than the cesium clock, which is now the standard for time and frequency measurements.

It is noted that as early as June, the International Bureau of Weights and Measures may publish the criteria needed for the future definition of the second. At the moment, none of the optical clocks are ready to work, but the new definition of a second could be officially approved as early as 2030.

It is noted that a more accurate one could help study dark matter. The fact is that time is related to gravity. Time can go slower at sea level, where the Earth’s gravitational field is stronger, than at the top of Mount Everest, where it is slightly weaker. Supercurrent clocks detecting a tiny slowing of time could find clots of dark matter.

We are talking about the exotic pentaquark and a pair of interconnected tetraquarks, which includes a new type of tetraquark. Thus, the list of hadrons found at the Large Hadron Collider has been expanded again.

It is reported that the new pentaquark was discovered as part of the analysis of decay events of negatively charged B-mesons. It consists of a charmed quark and an antiquark, and with them an upper quark, a lower quark, and a strange quark. All this makes it the first pentaquark in history to contain a strange quark.

The statistical significance level of the discovery was estimated at 15 (sigmas). For comparison, in particle physics in general about the discovery of the particle speak already at a significance level above five sigmas.

In turn, a new two-charged tetraquark with an open charm was observed together with its neutral counterpart in a joint analysis of decays of positively charged and neutral B-mesons. Their sigma level was 6.5 for the former and 8 sigma for the latter.
