Wooden sickles more than 7,000 years old found in Italy

Archaeologists presented the results of a study of three wooden sickles discovered during underwater excavations at the Early Neolithic site of La Marmotta in Italy. It turned out that these tools were made more than seven thousand years ago from oak and wood belonging to the rose family. Ancient people used resin from pine trees… Continue reading Wooden sickles more than 7,000 years old found in Italy

Archaeologists 50 years later rediscovered the ancient Church of St. Cyril in Smolensk at the mouth of Churilovka

Archaeologists spoke about the results of the work of the Smolensk expedition. A study of the sandy defensive rampart showed that the embankment on Cathedral Hill, built in the first half of the 9th century, currently reaches 1.5 meters in height and more than six meters in length. In addition, scientists have identified a large… Continue reading Archaeologists 50 years later rediscovered the ancient Church of St. Cyril in Smolensk at the mouth of Churilovka

Traces of ancient people about 90 thousand years old were found in Uzbekistan

Archaeologists have discovered a large Paleolithic site, Kuksarai-2, in the Western Tien Shan. In total, they found 455 stone artifacts, some of which allowed them to hypothesize that in ancient times there was a workshop site at this site. Optical dating has shown that the age of the oldest finds is about 89.8 thousand years.… Continue reading Traces of ancient people about 90 thousand years old were found in Uzbekistan

New Zealand cats caught hunting endangered bats

Zoologists have described two new cases of cats hunting endangered New Zealand bats. In one of them, a feral cat caught and ate a sheathwing in the forest, and in another, a free-roaming cat injured and killed several sheathwings near her home. As noted in the magazine article New Zealand Journal of Zoologymost likely cats… Continue reading New Zealand cats caught hunting endangered bats

American gull hatched chicks in Nizhny Novgorod

A Delaware gull native to North America has nested in Nizhny Novgorod. Her partner was a local glaucous gull, with which they bred hybrid offspring. According to the BirdGuides website, this is the second case of a Delaware gull breeding in Europe – and the first that has been documented. Birds often fly far from… Continue reading American gull hatched chicks in Nizhny Novgorod

After wolf attacks on livestock, Germans gave more votes to the right-wing Alternative for Germany party

The rise in popularity of the right-wing populist Alternative for Germany party is partly due to the recovery of the German wolf population. Scientists have found that residents of municipalities that have been attacked by these predators on livestock are more willing to vote for the AfD, whose members are critical of nature conservation and… Continue reading After wolf attacks on livestock, Germans gave more votes to the right-wing Alternative for Germany party

Scottish foxes eat dog feces

Zoologists have discovered that foxes living in the Scottish Highlands regularly eat the excrement of domestic dogs. They feed most actively on them during periods when the number of voles, their main prey, is low. Moreover, only 300-600 grams of dog droppings is enough to provide a fox with energy for the whole day. As… Continue reading Scottish foxes eat dog feces

The seismograph at the DESY synchrotron heard a Rammstein concert

The Rammstein concert had an unexpectedly strong impact on the operation of the seismograph serving the PETRA III X-ray source located at the DESY research center in Hamburg. About it reported official DESY Twitter account. It is noteworthy that the seismograph did not see sound, but transverse vibrations of the soil, the cause of which… Continue reading The seismograph at the DESY synchrotron heard a Rammstein concert

Polar bears from southeast Greenland switched to fresh ice due to lack of sea ice

Zoologists have discovered that the fjords of southeast Greenland are home to an isolated subpopulation of polar bears that have learned to survive in conditions of scarce sea ice. In the summer months, they hunt seals, using fresh ice brought by glaciers sliding into the sea as support. As noted in the magazine article Science,… Continue reading Polar bears from southeast Greenland switched to fresh ice due to lack of sea ice

Japanese chemists have created a synthetic analogue of aquaporins

Chemists from Japan have created a synthetic analogue of aquaporins, proteins that transport water through cell membranes. The scientists first synthesized ring-shaped molecules and then assembled them into nanochannels with a hydrophobic inner surface. The speed of water movement in nanochannels turned out to be two orders of magnitude higher than in natural aquaporins, while… Continue reading Japanese chemists have created a synthetic analogue of aquaporins
