Bushfire smoke raised temperatures in Australia by three degrees

British climatologists studied the distribution of smoke in the stratosphere after bushfires in Australia in 2019–2020. They found that black carbon particles in the smoke increased the average temperature in the lower stratosphere by 0.7 degrees worldwide, with temperatures rising by three degrees over Australia. Additionally, the reaction of smoke and ozone has caused the… Continue reading Bushfire smoke raised temperatures in Australia by three degrees

Physicists have proven the importance of the mesoscale for quantum phase transitions

Low-temperature phase transitions in ferromagnets are characterized by destruction of the domain structure. In an article in Nature physicists write that for a theoretical description of the dynamics of such transitions, it is necessary to take into account not only microscopic, but also mesoscale symmetry. This discovery indicates the possibility of the existence of non-classical… Continue reading Physicists have proven the importance of the mesoscale for quantum phase transitions

Ice-resistant self-propelled platform “North Pole” went on its first voyage

The research vessel North Pole has set out on its maiden voyage, the Arctic and Antarctic Research Institute said in a statement. It will carry an expedition to the Central Arctic, which will continue the research of the region begun in the 1930s. The 41st Arctic drifting polar station will continue regular research of the… Continue reading Ice-resistant self-propelled platform “North Pole” went on its first voyage

Ingenuity survived the Martian winter

The Martian drone Ingenuity made its first full flight after two months of inactivity, thereby confirming that it successfully survived the coldest part of the Martian winter. In the near future, the drone will receive a software update and will go to explore the delta of the ancient river in the Jezero crater. reported on… Continue reading Ingenuity survived the Martian winter

Archaeologists have discovered a bronze figurine of Jupiter in Taman

Archaeologists explored the ancient settlement of Red October-1, located in Taman. As a result of this work, they established that the fortified settlement arose at the turn of the 6th–5th centuries BC and existed until the modern era. Among the rare artifacts discovered at this site were a gray clay lamp in the shape of… Continue reading Archaeologists have discovered a bronze figurine of Jupiter in Taman

Ozonation of the air caused the skin to create an oxidative field around a person

Chemists from Germany, the USA and Denmark have found that substances secreted by human skin lead to the formation of an oxidative field around it. Scientists placed four people in a sealed mock-up office and began ozonizing the air to a level close to the maximum permissible concentrations. The experiment showed that ozone interacts with… Continue reading Ozonation of the air caused the skin to create an oxidative field around a person

Short breaks during the day helped workers cope with fatigue

Small breaks during the workday help you feel more alert, less tired and more productive. This was found by Romanian psychologists who conducted a meta-analysis of 22 studies published over the past 30 years. Article published in the magazine PLoS ONE. In modern culture, work and personal space no longer have clear boundaries, and more… Continue reading Short breaks during the day helped workers cope with fatigue

Traces of cockroach ootheca found in Jomon period ceramics

Archaeologists have examined 4,000- to 5,300-year-old Jomon period pottery discovered in Japan. In five artifacts they found traces of cockroach ootheca. One of them was laid by Japanese cockroaches (Periplaneta japonica), the rest look like smoky cockroaches (P. fulinginosa). Previously, it was believed that the latter species was brought to Japan only in the 18th–19th… Continue reading Traces of cockroach ootheca found in Jomon period ceramics

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
