Physicists have reproduced the chirping effect at the Kukulcan Pyramid

Colombian physicists have reproduced the unusual acoustic effect observed at the Temple of Kukulcan, located on the Yucatan Peninsula in Mexico. The echo of hand clapping at the base of the pyramid resembles the chirping or chirping of a bird. Simulations showed that this effect occurs due to the addition of many waves reflected from… Continue reading Physicists have reproduced the chirping effect at the Kukulcan Pyramid

Physicists achieve sub-picosecond switching of Bose condensate at room temperature

Chinese physicists reported that they were able to switch the states of condensed exciton-polaritons at room temperature using light in a time not exceeding one picosecond. In the future, this result can be used in the development of optoelectronic devices operating at terahertz frequencies. The study was published in Physical Review Letters. Semiconductor electronics to… Continue reading Physicists achieve sub-picosecond switching of Bose condensate at room temperature

Nepenthes has adapted to use the energy of falling raindrops to capture victims

One species of Nepenthes, a carnivorous plant common in the jungle, has evolved a mechanism that allows it to use the energy of raindrops for hunting. A drop of water falls on the leaf-cover of the plant and sends the insect sitting on it straight into the trap. However, it turned out that the mechanism… Continue reading Nepenthes has adapted to use the energy of falling raindrops to capture victims

Restorers at the National Gallery of Scotland, located in Edinburgh, have discovered a previously unknown self-portrait of Vincent van Gogh hidden on the back of another of his paintings, “Head of a Peasant Woman.” A new image will help shed light on the life of the great artist. The opening is announced in a press… Continue reading Van Gogh's self-portrait was found under glue and cardboard on the back of another of his paintings

A new ancient human tooth was discovered in Denisova Cave

Archaeologists have discovered a tooth of an ancient man in Denisova Cave. It represents a large molar, which, judging by its morphology, belonged to a Denisovan. This was reported by the Tolk publication with reference to the head of excavations in Denisova Cave, Mikhail Shunkov. In the Soloneshensky district of the Altai Territory, in the… Continue reading A new ancient human tooth was discovered in Denisova Cave

The MRO probe has compiled a new global multispectral map of Mars

The Mars Reconnaissance Orbiter team has released the first version of a global multispectral map of Mars that, when completed, will cover 86 percent of its surface and show the distribution of various minerals. It is expected that it will help in studying the geological evolution of Mars and searching for traces of the existence… Continue reading The MRO probe has compiled a new global multispectral map of Mars

Dust devils and rising winds appear to be responsible for dust haze on Mars

Planetary scientists working with the Perseverance rover have published the first results of observations of its system of weather sensors and dust. It turned out that daytime rising winds and convective vortices are responsible for maintaining a dust haze in the Martian atmosphere. On average, the rover recorded four whirlwinds per day, one of which… Continue reading Dust devils and rising winds appear to be responsible for dust haze on Mars

Two royal gyms from the early 16th century have been excavated in France.

During excavations on the territory of the French city of Blois, archaeologists discovered the ruins of two buildings from the early 16th century. It turned out that here were the royal halls for playing ball, which was very popular at the French court at that time. The construction of this unique sports complex, designed to… Continue reading Two royal gyms from the early 16th century have been excavated in France.

“The Fates of Icons in the Land of the Soviets”

At the end of the 1920s, the USSR government had many icons and not much money. Therefore, the icons went to Europe and the USA, and the money from there went to the needs of industrialization. In the book “The Fates of Icons in the Land of the Soviets. 1920–1930s” (NLO publishing house), historian Elena… Continue reading “The Fates of Icons in the Land of the Soviets”
