🔥🔥🔥🔥 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.

WhatsApp, a rival messaging platform, introduced some measures to counter disinformation when Covid-19 was first sweeping the world. However, the perpetrators of such frauds are now adopting new methods and technologies to defraud the investors. The original Telegram channel has expanded into a web of accounts for different locations, including specific pages made for individual Russian cities. There's also an English-language website, which states it is owned by the people who run the Telegram channels. At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup. Some privacy experts say Telegram is not secure enough
