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

The algorithm determined the mouse's pain level based on its muzzle expression

American scientists have developed a cloud platform that can assess the severity of pain in black laboratory mice. She analyzes the expression of the animal's face – the position of its nose, ears, whiskers and the degree of squinting of the eyes. Previously, researchers coped with this task manually, but, as the results show, the… Continue reading The algorithm determined the mouse's pain level based on its muzzle expression

James Webb takes its first direct image of an exoplanet

The James Webb Infrared Space Observatory has captured its first direct image of superjupiter HIP 65426b as it orbits the yellow-white dwarf in a wide orbit. The image made it possible to clarify the parameters of the planet and prove the high efficiency of the observatory in direct observations of exoplanets. A preprint of the… Continue reading James Webb takes its first direct image of an exoplanet

Daily inhalation of laughing gas left the patient unable to walk

American doctors described in The New England Journal of Medicine rare medical case. A patient was admitted to the hospital with symptoms of severe vitamin B deficiency.12 – impaired sensitivity and coordination of movements, up to the inability to walk. It turned out that over the past two months he had been inhaling nitrous oxide… Continue reading Daily inhalation of laughing gas left the patient unable to walk

Supernova 1181 fits the model of the merger of two white dwarfs

Astronomers from six countries have confirmed the idea that supernova SN 1181 AD, which exploded in 1181, represents the second remnant of a rare type of Iax supernova confirmed in the Milky Way. It is assumed that two carbon-oxygen white dwarfs or a massive carbon-oxygen dwarf with a helium companion merged without the resulting white… Continue reading Supernova 1181 fits the model of the merger of two white dwarfs

The genome of the “immortal” jellyfish has been sequenced

Spanish scientists have compiled a list of genes that are likely responsible for the “immortality” of the jellyfish Turritopsis dohrnii. To do this, they sequenced its genome and compared it with the genome of a jellyfish. Turritopsis rubra. It turned out that the “immortal” jellyfish, unlike its relative, acquired additional copies – up to eight… Continue reading The genome of the “immortal” jellyfish has been sequenced

Astronomers have found a record-breaking planetary nebula

Astronomers using ground-based telescopes have confirmed the discovery of a new planetary nebula in the Milky Way, which is the remnant of a star 2.8 times more massive than the Sun. The kinematic age of the nebula turned out to be record-breaking and amounted to 78 thousand years; it is part of an open star… Continue reading Astronomers have found a record-breaking planetary nebula

Insulin pump restores brain structure in diabetic teenagers

Researchers from the United States have found out how different methods of insulin administration affect brain development in adolescents with type 1 diabetes. Typically, this disease causes changes in the structure of the brain and leads to a decrease in cognitive abilities. But as it turned out, those who used an advanced insulin pump (which… Continue reading Insulin pump restores brain structure in diabetic teenagers

In Spain, a half-meter-long ancient Roman phallus was found carved on a building.

Spanish archaeologists discovered a bas-relief depiction of a phallus during excavations at El Higuerón in southern Spain. It was carved on the cornerstone of a large ancient Roman building that scientists are exploring in Nueva Carteya in the province of Cordoba, El Pais reports. Phallic symbols and images were widespread in ancient Rome. They were… Continue reading In Spain, a half-meter-long ancient Roman phallus was found carved on a building.

An ancient burial of a girl in a canoe found in Patagonia

Archaeologists have discovered an ancient canoe burial in the Argentine part of Patagonia. It contained the remains of a young and short girl, 17–25 years old, who was buried more than 840 years ago along with a ceramic vessel covered with white glaze and decorated with red geometric designs. This was reported in an article… Continue reading An ancient burial of a girl in a canoe found in Patagonia
