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.”
At the end of January 2012, Leah Segedie, a fitness blogger and founder of Mamavation, sounded the alarm about a childhood obesity campaign in Georgia that was shaming overweight kids. The Strong 4 Life campaign included a series of billboards, print ads, television ads, and social media featuring overweight children. The children talk about the negative social and health impacts of their size, including being excluded and made fun of by classmates.
In addition to the billboards coming down, it looks as though the Strong 4 Life campaign has made changes to the imagery on its website, twitter account and facebook page. Where the black and white images of children looking upset or ashamed used to appear, they now have images of children looking motivated, strong and confident.
Childhood obesity is a problem in Georgia. Thankfully, the activism of Leah Segedie and others in the blogging community, has helped the Strong 4 Life campaign move toward a more positive message. Motivating families and children to exercise and eat well and giving them the tools to do so can make a difference. Shaming them will only make things worse. The goals of the Strong 4 Life campaign have always been good, but now they have a fighting chance of being heard by those who need to hear them instead of hurting those who need their help.
A proposed set of guidelines for middle and high school science classes in Georgia has caused a furor after state education officials removed the word “evolution” and scaled back ideas about the age of Earth and the natural selection of species.
Despite the white beard, Charles Darwin isn’t Santa Claus, but like Christmas, Darwin Day comes once a year, and when it comes it brings good cheer. Across the country and around the world, at colleges and universities, schools and libraries, museums and churches, people assemble around February 12 to commemorate the life and work of the British naturalist. But it’s not just about Darwin: it’s about engaging in—and enjoying—public outreach about science, evolution, and the importance of evolution education.
“Listen carefully to today’s Republican right and you hear the same Social Darwinism Americans were fed more than a century ago to justify the brazen inequality of the Gilded Age: Survival of the fittest.”
The Republican’s base their agenda/excuses on a precept of the scientific theory of evolution. Science: what the Republican Party refutes and evolution: the evil the Republican religious party rails against. The creatures on the right grasp nothing, but these people of shallow minds fumble desperately in search for a way to support their nonsense with ideas they despise and do not understand. The Republican Party is the new definition of stupid.
Republican Party is SHIT.
