Physicists create first two-dimensional topological crystalline insulator
Quantum mechanics has long shown that particles can exhibit wave properties.
The robust properties arise at a deeper mathematical level: the symmetry of the system causes the energy spectra to intersect in a certain way, creating a structure on top of the quantum noise.
The discovery makes it possible to systematically search for or design materials that are at the quantum critical point and capable of forming topological structures.
Of particular interest to researchers was the fact that the maximum expression of the topological effect was observed precisely in the zone of the most intense quantum fluctuations.
Scientists from Aarhus University in Denmark have found that the natural amino acid arginine can reduce the risk of caries and suppress the formation of plaque.
The study focused on patients with active caries lesions.
The key point was separate exposure: one side of the prosthesis was treated with an arginine solution, and the other with plain water as a control.
On the side treated with arginine, the acidity level (pH) was significantly higher, which creates a less aggressive environment for the destruction of enamel.
The latest issue of the Daily Mail published an article highlighting a new theory proposed by scientists from Weill Cornell Medical Center in New York regarding the methods of construction of the Great Pyramid of Cheops.
According to new data, counterweights were used to lift the huge stone blocks, which moved along the inclined internal passages of the pyramid.
Study authors Dr. Simon Andreas Scheuring from Weill Cornell Medical Center in New York said that using a counterweight mechanism would significantly speed up the construction process.
On the walls of the interior, researchers found signs of wear and scratches, presumably left by sliding construction equipment.
The shrub Ptilotus senarius, which was considered extinct for more than half a century, has been rediscovered in Australia.
We are talking about the species Ptilotus senarius, which has not been recorded by scientists since 1967.
That changed after professional gardener Aaron Bean spotted an unusual shrub while working at a remote farming station in north Queensland.
As a result, Ptilotus senarius has been downgraded from extinct to critically endangered status.
