Revealed the cause of the glaciation of Antarctica 34 million years ago

Nature Communications: Antarctica is covered with ice due to the sinking of the ocean floor global cooling 34 million years ago, which led to the emergence of a thick ice sheet in Antarctica. According to a study published in the journal Nature Communications, the main role in this process was played not only by a decrease in the concentration of carbon dioxide in the Earth's atmosphere, but also by tectonic changes that affected the circulation of seawater in the Southern Ocean. Traditionally, it is believed that the change from hot greenhouse conditions to a cold climate in the early Cenozoic (from 52 to 34 million years ago) was due to a critical decrease in carbon dioxide in the atmosphere. Known as the Eocene-Oligocene Transition (EOT), these fundamental changes, which determined the state of the Earth's current climate, led to a decrease in the average surface temperature of the entire planet,

In Armenia, it was reported about the death of a conscript on the border with Azerbaijan

Armenian Defense Ministry: the body of an Armenian conscript was found on the border with Azerbaijan In Armenia, at one of the combat positions in the northeastern direction of the border with Azerbaijan, the body of an Armenian conscript was found. This was reported in the Ministry of Defense of the republic, reports “Sputnik Armenia”. It is noted that on November 24, at a combat position in the village of Tavush, the body of the deceased private Suren Avetisyan with a gunshot wound to the head was found. The Defense Ministry added that the circumstances of the incident are currently being clarified. Earlier, Armenia named the number of dead Armenian soldiers as a result of the November 16 battles on the border with Azerbaijan. According to the military department of the republic, six Armenian servicemen were killed during the clashes. The Azerbaijani side estimated its losses at seven dead and

Ukraine called the deadline for stopping the import of electricity from Russia and Belarus

Cabinet of Ministers of Ukraine: the country will stop buying electricity from Russia and Belarus by 2023 and Belarus by September 2023. The Ukrainian government announced the appropriate date on November 24 at a meeting, as part of the approval of a plan to combat the abuse of oligarchs. Interfax reports this. According to the plan, the Cabinet of Ministers will form a list of key objects of the country's fuel and energy complex. Further, these facilities will be included in the energy security strategy and will begin constant monitoring of threats to the energy sector. The document provides for tests on the autonomous operation of the energy system of Ukraine already in 2022. And a year later, Ukraine should stop buying electricity from Russia and Belarus. The Ukrainian government also paid attention to supplying the country with natural gas. By September 2023, the ministers plan to increase the number

Гинцбург: интраназальная вакцина даст Путину дополнительную защиту от COVID-19

«Назальная вакцинация может дать дополнительную защиту на уровне мукозального (местного) иммунитета, соответственно, появляются секреторные антитела, выстраивается второй барьер от коронавируса. Для этого вакцина и делается», — рассказал Гинцбург. Он добавил, что люди, сделавшие интраназальную вакцину в дополнении к обычной, скорее всего, станут обладателями стерильного иммунитета. Таким образом, они будут не только защищены сами, но и не рискуют стать переносчиками заболевания, подчеркнул Гинцбург. Ранее Путин рассказал, что в рамках ревакцинации привился и назальной вакциной от коронавируса. Он пояснил, что сначала ревакцинировался «Спутником Лайт», так как его уровень антител за 6 месяцев упал, а на следующий день сделал назальную вакцину.

The Russian offered to erect a monument to the elk killed by Rashkin

A resident of the Chelyabinsk region called for a monument to the elk killed by Deputy Rashkin A resident of the Chelyabinsk region Vitaly Orekhov whom Valery Rashkin, a State Duma deputy from the Communist Party of the Russian Federation, killed during the hunt. The Russian citizen's appeal is addressed to the Governor of the Saratov Region Valery Radaev, URA.RU reports. The author of the initiative posted a petition on the change.org portal. He explained that the monument will symbolize a protest against illegal hunting and support for the country's natural wealth. “The monument should be installed in the place where he gave his life for the sake of other people's greed and greed. Let the life and death of an unnamed moose not be in vain, “Orekhov noted. The activist clarified that the damage from the death of an animal can be estimated from 240 to 400 thousand rubles.

Ukraine received hundreds of millions of dollars from the IMF

The head of the National Bank of Ukraine: the second tranche was received from the IMF in the amount of $ 699 million ) for hundreds of millions of dollars, the head of the National Bank of the country Kirill Shevchenko said on Facebook. “Today Ukraine received the second tranche from the International Monetary Fund under the stand-by program in the amount of SDR 500 million (special drawing rights, SDR, special means of payment of the IMF – approx. “Lenta.ru” ) “, – Shevchenko wrote, indicating that it is about the equivalent of 699 million US dollars.

Ученые нашли белок, который активирует сон

Исследователи из израильского университета Бар-Илан провели эксперимент на рыбках данио, чтобы выяснить, что заставляет организм чувствовать усталость и засыпать. Как известно, в часы бодрствования в нейронах накапливаются повреждения ДНК. Это повреждение может быть вызвано различными элементами, включая УФ-свет, активность нейронов, радиацию, окислительный стресс и ферментативные ошибки. Во время сна и бодрствования системы восстановления в каждой клетке исправляют разрывы ДНК. В своих экспериментах ученые стремились определить, может ли накопление повреждений ДНК быть движущей силой, которая запускает гомеостатическое давление (ощущение усталости) и последующее состояние сна. Используя разные воздействия, исследователи вызвали повреждение ДНК у рыбок данио и следили за реакцией их организма. Выяснилось, что с увеличением повреждений ДНК, увеличивалась и потребность во сне.  В ходе экспериментов ученые обнаружили, что процесс сна запускает непосредственно белок PARP1, который является частью системы восстановления повреждений ДНК. Он одним из первых реагирует на увеличение повреждений и сигнализирует, что нужно срочно отдохнуть и восстановиться. Ученые подтвердили это путем стимулирования или блокирования белка — большое количество белка заставляло рыбок буквально засыпать на ходу, в то время как подавление белка сбивало сигнал о накопившейся усталости и не давало заснуть. Кроме того, в ходе исследования ученые узнали минимальное время
