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?

The world is ‘woefully underprepared’ for a massive volcanic eruption and the likely repercussions on global supply chains, climate and food, according to experts from the University of Cambridge’s Centre for the Study of Existential Risk (CSER), and the University of Birmingham.

The last known thylacine, also called the Tasmanian tiger, died at Australia’s Hobart Zoo in 1936. Now, a team of scientists believe they can resurrect the extinct species within 10 years, using stem cells and gene editing technology.
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.

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.
Experts behind the project claim the technology for “de-extinction” already exists, but others are sceptical.

We often wonder where all the aliens are out in the galaxy, but could it be that the technologies needed to get to space and travel the stars lead to inevitable catastrophe?
