Virologist Jean-Michel Claverie has spent over a decade studying "giant” viruses, including those nearly 50,000 years old found deep within Siberian permafrost — layers of frozen soil that are starting to thaw amid climate change. https://www.japantimes.co.jp/news/2023/10/10/world/science-health/scientist-50000-year-old-viruses/?utm_content=bufferd5eb9&utm_medium=social&utm_source=mastodon&utm_campaign=bffmstdn #worldnews #sciencehealth #science #viruses #paleontology #archaeology

Has chicken pox gotten milder?
Has glandular fever gotten milder?
Has mumps gotten milder?
Has rubella become milder?
Has measles gotten milder?
Has the three-day fever gotten milder?
Has the RS virus become milder?
Has the winter sickness gotten milder?
Has bird flu gotten milder?
Has TBE become milder?
Has HIV gotten milder?
Has Herpes gotten milder?

Why would SARS2 be any different?

"The insect world is full of species of parasitic wasps that spend their infancy eating other insects alive. And for reasons that scientists don’t fully understand, they have repeatedly adopted and tamed wild, disease-causing viruses and turned them into biological weapons. Half a dozen examples already are described, and new research hints at many more."

The media isn't covering it that much.

But ehhh... The fact that 20% of all milk sold in the US contains traces of bird flu should be a much much bigger story.

It's already everywhere there 🐄🐄

#pasteurization does kill #viruses

i'm not saying that it will kill #h5n1, i'm not speaking with authority here

i want to point out another problem:

#MAGA, which amplified #COVID by not wearing #masks and avoiding #vaccination, recently fell in love with #rawmilk, coincidentally:

https://www.politico.com/news/magazine/2024/03/10/the-alt-right-rebrand-of-raw-milk-00145625

please don't get me wrong, i am not saying raw milk drinking will become a vector. but the possibility is not zero. thanks to the same folks who killed so many with COVID

Happy to share the latest manuscript from our lab, in which we propose that eukaryotes evolved from a genomic chimera of Asgard archaea and giant viruses.

https://www.biorxiv.org/content/10.1101/2024.04.22.590592v1

This is a controversial topic, but we believe we have strong evidence to suggest a critical viral role in eukaryogenesis.

So you're risking it and visiting with friends or extended family indoors today...

In Angeles, covid levels are rising and on track to replicate last year's peak. I'd isolate for several days post potential exposure & maybe do a couple tests at 3 & 4 days point to protect others. Mask around others.

is near a peak much higher than last year's. anecdotally, persistent cough is a prevalent symptom this year. Mask & Wash hands frequently. Isolate if ill.

prevalence is rising STEEPLY and significantly higher than last year. Mask & wash hands frequently. Isolate if ill.

Zombie #Viruses Are Waking Up After 50,000 Years as Planet Warms
Bloomberg looks at "zombie viruses" — long-dormant #microbes which they call "yet another risk that #climatechange poses to #publichealth" as ground that's been frozen for "milleniums" suddenly starts thawing — for example, in the #Arctic, which is warming "faster than any other area on #earth."

I’m not dumb, ditzy on occasion but I get things eventually, however I read & see things constantly that are making me second guess myself; maddening

Prof Openshaw said: "The circulating now are pretty distant immunologically from the original which was used to make the early , or which last infected them.
"A lot of people have very little immunity to the viruses and their ."

WTF is this?!?!
THERE IS NO NOR HAS THERE EVER BEEN DURABLE IMMUNITY TO A VIRUS THAT HAS MUTATED MORE IN 3 YEARS THAN FLU IN 15+++++ YEARS even if you were just infected

I just cannot🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️

'#Obelisks': Entirely New Class of Life Has Been Found in The Human Digestive System
#Stanford biologist #IvanZheludev and colleagues argue their strange discovery may not be viruses, but instead an entirely new group of entities that may help bridge the ancient gap between the simplest #genetic molecules and more complex #viruses. "Obelisks comprise a class of diverse #RNA that have colonized, and gone unnoticed in, human, and global #microbiomes."

"On a sunny day 7 years ago in the Budongo Forest Reserve in Uganda, researchers were startled to observe chimpanzees scoop dry bat feces from under a hollow tree & devour it. In 60 years of observations at Budongo, no one had ever seen such a thing, recalls veterinary epidemiologist Tony Goldberg of the U of WI —Madison. “Aside from the ick factor, we all had the exact same thought. They must be exposed to horrible bat-borne .”
That suspicion proved correct. Though the bat feces is rich in nutrients, it contains dozens of previously unknown viruses. These novel pathogens include a new —a relative of the one that causes -19.
Ordinarily, chimps & other animals in the area get these minerals by eating the pith of the raffia palm.
Local tobacco farmers nearly extirpated the palm to make string to tie up tobacco.

When the palm disappeared, chimps, monkeys, & antelopes had to look for other nutrient sources, including clay & bat dung"https://archive.ph/qeBEC#selection-1543.156-1561.147

Impressive depiction of a #bacteriophage launching an assault on a bacterial cell. Bacteriophages, resembling creatures from a science fiction thriller, are specialized #viruses that target and infect bacterial cells by binding to specific surface proteins. They inject their #genetic material to hijack the bacterial machinery for replication, ultimately leading to the demise of the bacterial #cell.
