1 in 6 Chance of Catastrophic Volcano Eruption Within a Hundred Years

Posted by in categories: climatology, existential risks

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.

Scientists plan ‘de-extinction’ of Tasmanian tiger

Posted by in categories: bioengineering, biotech/medical, existential risks

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.

‘Jurassic Park’? Scientists want to resurrect Australia’s Tasmanian tiger

Posted by in categories: biotech/medical, existential risks, genetics

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

Posted by in categories: climatology, existential risks, military

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.

Tasmanian tiger: Scientists hope to revive marsupial from extinction

Posted by in category: existential risks

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

For 15 Years, America’s Secret Nuclear Launch Codes Were “00000000”

Posted by in categories: existential risks, military, nuclear weapons

I heard they changed it to 80085.

Some say that truth is often stranger than fiction. According to a 2004 memo by Dr. Bruce Blair, a former Minuteman missile launch control officer, the U.S. Strategic Air Command (SAC) once intentionally set the launch codes at all Minuteman nuclear missile silos in the U.S. to a series of eight zeroes.
