That is extremely concerning, we will have to be 100% cautious while handling these ancient viruses, it's crazy how a virus can put itself to deep sleep for over 20,000 years.

My grim intrusive thoughts are that we’re heading into an era of complex problems (the climate, regulating and taming capitalism, public health, public infrastructure) that require collective action and likely require more cohesive nation-states than most of the world has available to them, a huge shift from the prior 75 years and one that could prove devastating to regions like the Americas with low-cohesion, high-diversity histories. I don’t want to die and be buried in Planet Nazbol.

A team of climate scientists from France, Russia and Germany has found that ancient viruses dormant for tens of thousands of years in permafrost can infect modern amoeba when they are revived. For their study, reported on the open-access site Viruses, the group collected several giant virus specimens from permafrost in Siberia and tested them to see if they could still infect modern creatures.

Prior research has shown that permafrost—frozen soil—is an excellent preservative. Many carcasses of frozen extinct animals have been extracted from permafrost in the Northern Hemisphere. Prior research has also shown that plant seeds lying dormant in permafrost can be coaxed to grow once revived. And there is evidence suggesting that viruses and bacteria trapped in permafrost could infect hosts if revived. In this new effort, the researchers tested this theory.

The effort by the research team followed up on prior work in 2014 that showed a 30,000-year-old virus could be revived—and that it could be infectious. The team followed up on that effort by reviving a different virus in 2015 and allowing it to infect an amoeba. In this new effort, the team collected several virus specimens from multiple permafrost sites across Siberia for lab testing.

For safety reasons, the research team collects only so-called giant viruses and only those that can infect amoeba, not humans or any other creature. In reviving the virus samples, the team found that they were still capable of infecting amoeba. They also found, via radiocarbon dating of the permafrost in which they were found, that the viruses had been in a dormant state for between 27,000 and 48,500 years

From the article: A new report published in Cell Reports Medicine has found that individuals who use assigned breathwork techniques experienced greater improvements in mood and lowered respiratory rates as compared to those practicing mindfulness meditation. These findings indicate that breathwork may be an important therapeutic tool for those experiencing depressed mood or an overactive nervous system.

Amidst the COVID-19 pandemic, breathwork has become a popular and cost-effective intervention for improving health and well-being through intentional breathing techniques. Numerous scientific studies have demonstrated how we breathe affects our heart rate, blood pressure, oxygen levels, and ventilation. In addition, initial research has provided evidence that techniques like slow and nasal breathing can enhance the quality of life for asthma patients, reduce anxiety, and improve alertness and learning abilities in people.

I agree that FMT holds great potential, but it needs more research. How to select a safe and effective donor is unknown still. I've been trying to figure it out, and after screening 100k applicants I tried the #1 ranked donor and got worse.

It would be nice if other research groups would pair up with me to help try to figure out the donor quality puzzle.
