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 population of the ancient Carthaginian city turned out to be genetically diverse

Paleogeneticists have read 30 genomes of ancient inhabitants of Tunisia, central Italy and Sardinia dating back to the Iron Age. In all regions, they found both descendants of more ancient local populations and immigrants from other territories. Thus, in the necropolis near the Carthaginian city of Kerkuan there were the remains of the descendants of… Continue reading The population of the ancient Carthaginian city turned out to be genetically diverse

Paleogeneticists read the genome of the “warrior with a griffin” from Nestor’s palace

Paleogeneticists have studied the origins of populations whose history is known from written sources. They discovered that the Mycenaeans arose from the mixing of Minoans and migrants whose origins were connected with the Eurasian steppe. However, the famous “warrior with a griffin,” whose rich burial was found in Pylos several years ago, did not have… Continue reading Paleogeneticists read the genome of the “warrior with a griffin” from Nestor’s palace

A 19th-century English farmer was accused of invading Australia by rabbits.

Biologists have found out who should be blamed for the environmental disaster caused by rabbits brought to Australia. Genetic analysis has shown that almost the entire local population of these animals descends from 13 wild and domestic individuals and their descendants, which were received from England in 1859 and released on his estate by settler… Continue reading A 19th-century English farmer was accused of invading Australia by rabbits.

Neolithic Balkan herders hunted roe deer

Paleozoologists from the USA and Croatia examined more than 41 thousand animal bones and teeth found in six ancient settlements in northern Dalmatia. It turned out that during the Neolithic period (about 6000–4700 BC), local residents mainly raised goats and sheep, but over time the share of cattle and pigs increased. Moreover, in the early… Continue reading Neolithic Balkan herders hunted roe deer

Entomologists have reconstructed the chirping sound of a grasshopper found 150 years ago

Entomologists studied the grasshopper Prophalangopsis obscura, the only specimen of which was collected in northern India 150 years ago. As a result, it was possible to find out the frequency of its chirping. It turned out to be quite low, about 4.7 kilohertz. Such sounds carry far and can give away the location of the… Continue reading Entomologists have reconstructed the chirping sound of a grasshopper found 150 years ago

Zoologists accidentally discovered a new species of deep-sea giant isopods in a Japanese aquarium

Zoologists have discovered a previously unknown species of giant isopod from the Gulf of Mexico, which reaches 26 centimeters in length and has a creamy yellow color. It got the name Bathynomus yucatanensis. As noted in the magazine article Journal of Natural Historythe species was described from a single specimen from a Japanese aquarium, which… Continue reading Zoologists accidentally discovered a new species of deep-sea giant isopods in a Japanese aquarium

Archaeologists have discovered Britain's oldest millet

Archaeologists have discovered the remains of a building and a pit near Norwich, England, built by people in the late Bronze Age. In addition to charcoal and several artifacts, scientists found the remains of cultivated plants: flax, wheat, barley and millet. Radiocarbon dating has shown that it is the oldest millet in Britain, grown around… Continue reading Archaeologists have discovered Britain's oldest millet

Eruption resumes on Iceland's Reykjanes Peninsula

An eruption began on the Icelandic Reykjanes Peninsula on August 3 at 16:18 Moscow time. About it reported Icelandic Meteorological Centre. Lava has begun pouring out of a new fissure in the Meradalir Valley, which neighbors the site of the 2021 Fagradalsfjall eruption. The opening of the crack was preceded by a swarm of earthquakes… Continue reading Eruption resumes on Iceland's Reykjanes Peninsula

Paleogeneticists read the oldest genome of a domestic horse from America

Paleogeneticists have read the oldest genome of the domestic horse from the Americas. They were able to sequence DNA from a tooth found in an early colonial Spanish town in Haiti. Scientists have confirmed past findings that the first domestic horses of the New World originated from the Iberian Peninsula. This was reported in an… Continue reading Paleogeneticists read the oldest genome of a domestic horse from America
