$225 billion drug giant Novartis is taking a fresh approach to cancer treatment, and it could help prepare it for a ‘doomsday scenario’

Posted by in categories: biotech/medical, existential risks

Pharma giant Novartis is developing drugs that could prevent cancer before patients get it. One big question: how will we pay for them?

Don’t Bring Extinct Creatures Back to Life

Posted by in categories: biological, existential risks

What if woolly mammoths could walk the planet once again? De-extinction – or the process of creating an organism which is a member of, or closely resembles, an extinct species – was once a sci-fi fantasy only imaginable in films like “Jurassic Park.” But recent biological and technological breakthroughs indicate that reviving extinct creatures could become a reality. Even if advancements get us there, should we do it?

Asteroid Impacts Increased Around Time of Largest Extinction Event

Posted by in categories: asteroid/comet impacts, existential risks

Dinosaurs never stood a chance once asteroid impacts more than doubled some 290 million years ago.

By studying the Moon, an international team of scientists revealed that the number of asteroids crashing into Earth and its satellite increased by two to three times toward the end of the Paleozoic era.

Contrary to popular belief, most of the planet’s more primitive asteroid-produced craters were not erased by erosion and other geologic processes.

NASA will attempt to knock an asteroid out of orbit for the first time in 2022

Posted by in categories: asteroid/comet impacts, existential risks

  • If an asteroid were to head towards Earth in the foreseeable future, we would be quite defenceless.
  • To change that, NASA has approved a mission to throw a “small” asteroid off course in October 2022.
  • The aim of the project is to establish whether we can protect our planet from a future asteroid impact.

If an asteroid were to head towards Earth, we would be quite defenceless as we have not successfully developed a method that could reduce the impact of — or entirely avert — a devastating collision.

However, that may be about to change. NASA has approved a project called the Double Asteroid Redirection Test (DART), the aim of which is to throw a “small” asteroid off course in October 2022.

Time to Say Goodbye to Coffee?

Posted by in categories: climatology, existential risks, finance, sustainability

Saying farewell to coffee isn’t that easy. According to research about three-fifths of all our beloved coffee species are going to go extinct. This is a phenomenal amount of coffee that we risk losing.

Here’s something to think about as you sip that morning mochaccino:?Deforestation, climate change and the proliferation of pests and fungal pathogens are putting most of the world’s wild coffee species at risk of extinction.

At least 60 percent of wild coffee species are considered “threatened,” according to a study published this week in Science Advances. And fewer than half of all the wild species are safeguarded in so-called germplasm collections—banks for seed and living plants kept in protected areas as backups.

Why it is dangerous to build ever larger big bang machines

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.

Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”

“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”

Scott Aaronson — The Winding Road to Quantum Supremacy

This was the first part in an interview series with Scott Aaronson — this one is on quantum computing — other segments are on Existential Risk, consciousness (including Scott’s thoughts on IIT) and thoughts on whether the universe is discrete or continuous.

Ok, the new version of my global risk prevention map is up (pdf link is in comments) and now it is accompanied by recently the published article “Approaches to the Prevention of Global Catastrophic Risks.”

Abstract: Many global catastrophic and existential risks (X-risks) threaten the existence of humankind. There are also many ideas for their prevention, but the meta-problem is that these ideas are not structured. This lack of structure means it is not easy to choose the right plan(s) or to implement them in the correct order. I suggest using a “Plan A, Plan B” model, which has shown its effectiveness in planning actions in unpredictable environments. In this approach, Plan B is a backup option, implemented if Plan A fails. In the case of global risks, Plan A is intended to prevent a catastrophe and Plan B to survive it, if it is not avoided. Each plan has similar stages: analysis, planning, funding, low-level realization and high-level realization. Two variables—plans and stages—provide an effective basis for classification of all possible X-risks prevention methods in the form of a two-dimensional map, allowing the choice of optimal paths for human survival. I have created a framework for estimating the utility of various prevention methods based on their probability of success, the chances that they will be realized in time, their opportunity cost, and their risk. I also distinguish between top-down and bottom-up approaches.

How The 1% Will Live After The End Of The World | VICE on HBO (Bonus)

Posted by in category: existential risks

Throughout human history, doomsayers — people predicting the end of the world — have lived largely on the fringes of society. Today, a doomsday industry is booming thanks to TV shows, movies, hyper-partisan politics and the news media. With the country’s collective anxiety on the rise, even the nation’s wealthiest people are jumping on board, spending millions of dollars on survival readiness in preparation for unknown calamities. We sent Thomas Morton to see how people across the country are planning to weather the coming storm.
