A mysterious giant virus buried for 30,000 years in Siberian permafrost has been resurrected.
The virus only infects single-celled organisms and doesn’t closely resemble any known pathogens that harm humans.
Even so, the new discovery raises the possibility that as the climate warms and exploration expands in long-untouched regions of Siberia, humans could release ancient or eradicated viruses. These could include Neanderthal viruses or even smallpox that have lain dormant in the ice for thousands of years.
In recent years, Claverie and his colleagues have discovered a host of giant viruses, which are as big as bacteria but lack characteristic cellular machinery and metabolism of those microorganisms. At least one family of these viruses likely evolved from single-celled parasites after losing essential genes, although the origins of other giant viruses remain a mystery, Claverie said.

The findings raise the possibility that other long-dormant or eradicated viruses could be resurrected from the Arctic. As the climate warms and sea ice and permafrost melt, oil and mining companies are drilling many formerly off-limit areas in Russia, raising the possibility that ancient human viruses could be released.
For instance, Neanderthals and humans both lived in Siberia as recently as 28,000 years ago, and some of the diseases that plagued both species may still be around.
"If viable virions are still there, this is a good recipe for disaster," Claverie said. "Virions" is the term used for the virus particles when they are in their inert or dormant form.
Doom…despair…agony on end…deep, dark depression…finally, setting in…
Darwin did not write the book of horseshit, a goat fucking misogynist did way back when folks made human sacrifice to the seasons for a bountiful harvest.

The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to new research, iron in the dinosaur’s body preserved the tissue before it could decay.
The find was also controversial, because scientists had thought proteins that make up soft tissue should degrade in less than 1 million years in the best of conditions. In most cases, microbes feast on a dead animal’s soft tissue, destroying it within weeks. The tissue must be something else, perhaps the product of a later bacterial invasion, critics argued.
Then, in 2007, Schweitzer and her colleagues analyzed the chemistry of the T. rex proteins. They found the proteins really did come from dinosaur soft tissue. The tissue was collagen, they reported in the journal Science, and it shared similarities with bird collagen — which makes sense, as modern birds evolved from theropod dinosaurs such as T. rex.
Dinosaurs’ iron-rich blood, combined with a good environment for fossilization, may explain the amazing existence of soft tissue from the Cretaceous (a period that lasted from about 65.5 million to 145.5 million years ago) and even earlier. The specimens Schweitzer works with, including skin, show evidence of excellent preservation. The bones of these various specimens are articulated, not scattered, suggesting they were buried quickly. They’re also buried in sandstone, which is porous and may wick away bacteria and reactive enzymes that would otherwise degrade the bone.
Sometimes girls just want to have fun. And sometimes, they just want to play football. Twelve-year-old Maddy Blythe is one such girl. The middle-schooler was her team’s first-string defensive tackle, with four or five sacks to her credit, when Strong Rock Christian School in Locust Grove, Georgia kicked her off the team.
"Just for being a girl," Blythe said in an interview with wsbtv.com.
When Maddy and her mother, former cop Cassie Blythe, pressed for further explanation, they said they were told the reasons inlcuded the fact that the boys might have “lustful thoughts,” and that they would likely use “rough language” in the locker room. Other explanations included, “Middle school girls should play middle school sports.” Finally, the head of the school told the Blythes that prayer had informed his decision.
The twisting tale of DNA
Creationist wizard (Todd Akin) and theologian raconteur (David Barton), assisted by their supernatural beans genetically manufactured a creature made from the DNA of human beings and tarantula spiders. The resulting adroit creature is proof of the persistence of god crap, as its intelligent design is irrefutably divine.
God has blessed the US Military….do si do, one step two, it malfunctions and falls on you.
"The affinities of all the beings of the same class have sometimes been represented by a great tree… As buds give rise by growth to fresh buds, and these if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever branching and beautiful ramifications."
Charles Darwin, 1859
I’ve done material about evolution before, and in Australia and in Britain, it barely raises an eyebrow, it’s just worth a chuckle. But in America, it’s quite contentious to do comedy about evolution, you know, it gets a gasp. It’s the equivalent of doing material about fisting anywhere else. It’s quite confronting for them.
Roger Cone is a microbiologist, not a politician. He struggles with a basic truth: For all the scientific acceptance of evolution, many Americans simply don’t believe it is factually accurate.
And when Tennessee lawmakers passed a measure allowing teachers to question accepted theories on evolution and climate change in the classroom, Cone acted. He and two other scientists wrote an op-ed in The Tennessean last month opposing the bill, which he says “started out as a backdoor attempt to get creationism, or ‘intelligent design,’ taught in the schools.” He fears it will be another black eye for Tennessee — a throwback to the 1925 Scopes “monkey trial,” when teacher John T. Scopes was put on trial for lecturing on Charles Darwin’s theory of evolution.
"There are certain issues that have become political, such as climate change and the extinction crisis, in which there’s a very clear distinction between what we know scientifically and the claims some politicians make," he says.
The Tennessee controversy is only the latest example of scientists leaving their labs and universities, and clashing with politicians.
“Darwin took us forward to a hilltop, from where we could look back and see the way from which we came.”
House lawmakers this week advanced the controversial “Don’t Say Gay” bill, moving it forward from a House Education committee on a 8-7 vote.
Critics have said the legislation, even in its modified form, will have a chilling effect on how teachers deal with anti-LGBT bullying, that it is entirely unnecessary given that Tennessee already has a strict no sex education before highschool policy, and that it is simply about pushing a conservative religious agenda.
A Tennessee bill meant to protect teachers who allow students to question and criticize “controversial” subjects such as evolution and climate change became law on Tuesday after Gov. Bill Haslam (R) declined to act.
The state legislature had sent the bill to Haslam earlier this month. He had until Tuesday to veto it, sign it or allow it to pass without his signature.
Critics of the legislation have dubbed it the “Monkey Bill” and charge that it is anti-science, backdoor approval of the teaching of religion in schools that reminds of the state’s history with the Scopes Trial.
Tennessee is still leading the way in backward, bigoted and homophobic agendas and Republican inbred bible humping honkies for a whiter corporate America. Afghanistan might be a better place to live.
GOP is SHIT.
We can’t help but wonder what it will take to make state legislators understand that undermining the teaching of evolution in order to promote religious beliefs like creationism and intelligent design in public schools is simply unconstitutional.
And then it hit us: Maybe we just aren’t using the right word to explain it. So, in case any confusion remains, Tennessee legislators take note: Under the Establishment Clause of the First Amendment to the U.S. Constitution, your repeated attacks on evolution education are unlawful, illegal, illicit, impermissible, unauthorized, improper, prohibited, barred, lawless, banned, illegitimate, forbidden, unsanctioned, proscribed, and (something to always keep in mind) actionable. See, we have a thesaurus too, and we are not fooled when the legislature plays semantics with constitutional violations. Whether you call it teaching the “controversy,” the “debate,” the “disputation,” or any other variation on those terms, we know what the endgame is, and, in our brackets, we are still betting on the Constitution.
Call science a religion. Which is strange. To call something a religion (faith based) when it is not a religion, just to bring it down to the level of what you believe in (something unacceptable in public schools) while you are trying to elevate what you believe in to the level of science, pretty much illuminates that there are warped and unintelligent people behind “intelligent design”.
Rename Creationism into “Intelligent Design” and claim “intelligent design” is not religion and try to push it on school boards
Have lots of quasi-intellectuals, pseudo-scientists attempting to present intelligent design as a reasoned study which somehow single-handedly and magically casts doubt on theory of evolution (praise the lord), simultaneously offering an alternative theory (praise the lord again) that all that is around us is of someone’s design (and again, yawn feel free to praise your fucking gourd).
- I, personally don’t believe in god, any god. I think people create god and most people who believe in gods are not stupid enough to create a stupid god who is so stupid as to be behind the horseshit that is “intelligent brain dead design”. “Intelligent design” is the definition of stupid and those pushing “Intelligent design” into our public schools offer stagnation and mental cancer to America’s children.
Intelligent design is proof of only one thing: that desperate fools are not extinct.
Evolution is the fundamental idea in all of life science, in all of biology. According to Bill Nye, aka the science guy, if grownups want to “deny evolution and live in your world that’s completely inconsistent with everything we observe in the universe, that’s fine, but don’t make your kids do it because we need them.”
