According to NASA’s database, a space rock will approach Earth in the following days at a speed of about 30,000 miles per hour.

What Happens When the Doomsday Clock Hits Midnight?
The invasion that Russia has wrongfully started in Ukraine has led to more people talking about the threat of Nuclear war and World War 3. How does the Doomsday Clock relate to all this?

Script:
Since 2020, the Doomsday Clock has been set to 100 seconds to midnight. Which is the closest its ever been to midnight in its 75 years of existence. As the scientists who set the clock put it: we’re “at doom’s doorstep.”
The Doomsday Clock is a metaphor to remind humans how close we are to destroying our planet through the technology we develop, with midnight representing the apocalypse. It’s a symbol to remind us to address these dangers so that we can survive on our planet. It was created by the Bulletin of the Atomic Scientists, an organization founded by scientists at the University of Chicago who worked on the Manhattan Project, which was America’s effort to develop atomic weapons during the Cold War.
When the Doomsday Clock debuted in 1947, its creator, artist Martyl Langsdorf, set it to 7 minutes to midnight. She was married to a physicist who worked on the Manhattan Project. When she heard him and other scientists talk about the consequences of developing this dangerous technology, she created the clock to show that we didn’t have much time left to get atomic weapons under control.

‘Jurassic Park’? Scientists want to resurrect Australia’s Tasmanian tiger
Is de-extinction realistic?
Scientists in the US and Australia have announced a multi-million dollar project — resurrecting the extinct Tasmanian tiger. The last known marsupial officially called a thylacine, died in the 1930s. According to the team, the extinct thylacine can be recreated using stem cells and gene-editing technology, and the first one could be “reintroduced” to the wild within 10 years.
We would strongly advocate that first and foremost we need to protect our biodiversity from further extinctions, but unfortunately we are not seeing a slowing down in species loss.

Nuclear War Would Cause a Global Famine and Kill Billions, Rutgers-Led Study Finds
We might all starve.
Researchers from Rutgers University calculated the possible effects of nuclear wars. The result shows that a nuclear war between countries such as Russia and USA could kill billions and cause starvation within two years.
It also demonstrates that large deficits would arise in imports due to the depletion of crops.
Every human being is afraid of nuclear war beyond any doubt. Researchers went into overdrive to see what would happen when a nuclear war broke out, dangerous enough to bring the end of humanity as well as all life on Earth.
More than 5 billion people would die of hunger following a full-scale nuclear war between the U.S. and Russia, according to a global study led by Rutgers climate scientists that estimates post-conflict crop production.
“The data tell us one thing: We must prevent a nuclear war from ever happening,” said Alan Robock, a Distinguished Professor of Climate Science in the Department of Environmental Sciences at Rutgers-New Brunswick and co-author of the study. Lili Xia, an assistant research professor in the School of Environmental and Biological Sciences, is lead author of the study published in the journal Nature Food .
