Microbes guilty of killing 90% of the world's former inhabitants

Methanosarcina are ocean living microbes , although they are part of the global ecosystem , scientists at MIT have directly blamed these small creatures for wiping out around 90% of Earth's former inhabitants some 252 million years ago . The sea living microbes survive on organic carbon and nickel pumped by volcanic eruptions , and in return they release methane giving rise to a highly acidic ocean and a poisonous atmosphere. Due to the apocalyptic event caused by a large meteor strike and uncontrollable volcanic eruptions ,the amount of carbon dioxide in the atmosphere and the ocean increased rapidly , however the volcanic eruptions , according to the new findings , was just one of the contributors for the downfall of Earths former biosphere. The MIT Team found signs of high carbon containing gasses in previous rock sediment research projects caused by the said Eruptions,however as the volcanoes die down , the level of Carbon gases should gradually decrease as well , but according to Gregory Fournier of MIT it is not so and "Instead, we see the opposite: a rapid, continuing increase". The reason behind this is now linked to our microbial culprits - Methanosarcina .

According to the study , the Microbes quickly adapted to their new CO2 rich waters and started producing Methane as output ,The increase in Nickel due to the eruptions might have also played a part and according to Gregory , "That suggests a microbial expansion. The growth of microbial populations is among the few phenomena capable of increasing carbon production exponentially, or even faster."

Due to this combination , the excess release of harmful gases affected the temperature of the oceans and the atmosphere making most marine life extinct ,creatures on land suffered a similar fate as most of the reptiles and mammals ran out of plant life for food leading to a collapse in the food chain . however creatures that escaped destiny adapted and grew into the bio-diverse world we live in now .

iPad (2022) and iPad Pro with M2 announced

Apple has announced their latest iteration of the iPad (entry level model) and the iPad Pro lineup with the new M2 processor. The event, held on the 18th of October as a recorded session displayed the key features of the iPads with the most significant being the base model iPad which has now received an upgrade. iPad 2022 This model of the base model iPad ditches the almost 12 year old home button and display layout and goes for a cleaner display only design found on the iPad Air . The chassis, which now comes with flatter sides and a TouchID fingerprint sensor on the top has also abandoned the lightning port in favor of USB C and it also comes with a set of pogo style connectors for accessories including a keyboard with trackpad. Internally, the iPad comes either as a Wifi only (Wifi6) and a 5G cellular model and is offered with 64 or 256GB of storage. The processor has also been upgraded to the Apple A14 which is the same found on the iPhone 12 series and last year's iPad Air. L

Nikon D850 is official

Nikon D850 has probably been the company's worst kept secret . The camera , which was announced a month back during Nikon's 100 year anniversary just explained in brief ,but thanks to leakers some of that information managed to hit the internet and inadvertently lead the camera to be the most talked about topic in the camera world . But now , after a month of waiting anxiously for the official pricing (rumors made headlines after many quoted $1000-2000 more than the official one ) , the Nikon D850 is finally official . Nikon D850 The Nikon D850 is Nikon's jack of all trades semi - flagship camera which sits below the D5 but above the D750 . The model which succeeds the D810 from almost 3 years back is armed with a new backlit 35mm sensor and the largest optical viewfinder and pentaprism for any camera . Video features on the camera include 4K with full sensor readout and features 8K timelapse . The camera features 7 fps at full resolution and 9fps when connecte
