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 smell of a woman prevented an antidepressant from calming mice

Scientists from the USA and Cyprus have found that the gender of the experimenter can influence the results of medical experiments on mice. It turned out that the smell of men causes stress in animals and a desire to escape from its source. But if a man injects a mouse with an antidepressant, its effect… Continue reading The smell of a woman prevented an antidepressant from calming mice

NASA has fixed a glitch in Voyager 1's telemetry sending system.

The Voyager 1 team solved the problem of sending anomalous telemetry that had been coming from the probe for several months. It turned out that the cause of the failure was a faulty on-board computer, which was mistakenly assigned the operation of sending data. The problem has now been fixed, according to NASA's website. Voyagers… Continue reading NASA has fixed a glitch in Voyager 1's telemetry sending system.

Burial of a woman with a 1,400-year-old folding chair unearthed in Germany

Archaeologists have discovered the burial of a woman in Middle Franconia who died at approximately 40–50 years of age around 600 AD. Among her accompanying equipment was a folding iron chair. This is only the second such discovery from the early Middle Ages made in Germany. This was reported in a press release from the… Continue reading Burial of a woman with a 1,400-year-old folding chair unearthed in Germany

People buried in an English well turned out to be victims of a medieval pogrom

Scientists from the UK and Germany examined the remains from a collective burial in a well, discovered in the center of Norwich, England in 2004. Radiocarbon dating showed that these people, many of whom were children, died between 1161 and 1216 AD. Paleogenetic research and historical evidence indicate that the remains belonged to Ashkenazi Jews,… Continue reading People buried in an English well turned out to be victims of a medieval pogrom

Thousand-year-old remains of a man with XXY chromosomes discovered in Portugal

The remains of a man who lived more than a thousand years ago were discovered in Portugal. This adult was found to have a very wide ilium, malocclusion, and maxillary prognathism. Genetic analysis showed that the man had Klinefelter syndrome – he belonged to the karyotype 47, XXY. This was reported in an article published… Continue reading Thousand-year-old remains of a man with XXY chromosomes discovered in Portugal

A candidate for an artificial radio signal from an Earth-like exoplanet turned out to be of terrestrial nature

Astronomers have concluded that the unusual narrow-band radio signal recorded in the direction of the Kepler-438 exoplanet system last year by the FAST telescope is not a technosignature, but is of anthropogenic origin. This is indicated by the polarization properties of the signal. A preprint of the work was published on arXiv.org. To answer the… Continue reading A candidate for an artificial radio signal from an Earth-like exoplanet turned out to be of terrestrial nature

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

Planetologists have confirmed the possibility of delivering volatile substances to the young Earth by asteroids

Planetologists presented new results from analyzing soil particles from the Ryugu asteroid in laboratory conditions. It turned out that the temperature inside Ryugu’s parent body could not exceed 30 degrees Celsius, and asteroids like Ryugu could indeed deliver volatile substances to the young Earth. Article published in the magazine Nature Astronomy.The near-Earth 900-meter asteroid Ryugu,… Continue reading Planetologists have confirmed the possibility of delivering volatile substances to the young Earth by asteroids
