🔥🔥🔥🔥 Olimlar Yer yuzida eng qadimgi meteorit kraterining izlarini aniqladilar
Uning yoshi 3,47 milliard yil bo‘lib, avvalgi eng qadimgi deb hisoblangan Yarrabubba krateridan (2,23 milliard yil) 1,2 milliard yilga qadimgi ekanligi ma’lum bo‘ldi.
U G‘arbiy Avstraliyaning Sharqiy Pilbara hududida, Antarctic Creek Member jins qatlamida topildi. Asosiy dalillardan biri “singan konuslar” bo‘lib, ular jinslarda hosil bo‘lgan konussimon yoriqlar bo‘lib, kuchli bosim ta’sirida paydo bo‘lgan. Tadqiqotchilarning baholariga ko‘ra, bu kraterning diametri kamida 100 km bo‘lgan.
Olimlarning fikricha, bunday ulkan ta’sirlar qit’alarning shakllanishiga, vulqonlarning faollashishiga va hayotning paydo bo‘lishiga yordam bergan bo‘lishi mumkin. Krater qatlamlarida qadimgi qazilma qoldiqlari ham topilgan bo‘lib, ular dastlabki fotosintez qiluvchi mikroorganizmlarga bog‘liq bo‘lishi ehtimoli bor.

It is unclear who runs the account, although Russia's official Ministry of Foreign Affairs Twitter account promoted the Telegram channel on Saturday and claimed it was operated by "a group of experts & journalists." That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. This ability to mix the public and the private, as well as the ability to use bots to engage with users has proved to be problematic. In early 2021, a database selling phone numbers pulled from Facebook was selling numbers for $20 per lookup. Similarly, security researchers found a network of deepfake bots on the platform that were generating images of people submitted by users to create non-consensual imagery, some of which involved children. Telegram Messenger Blocks Navalny Bot During Russian Election On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations.
