This time Mary Schweitzer’s team found keratin protein on a claw of an ostrich-sized dinosaur from Mongolia.If you put a chicken under a sand dune, will it last for 75 million years? That’s what a report on PhysOrg seems to imply. Like some bird claws, the claws of dinosaurs have a keratinous sheath that covers the digits. Some of the protein from that sheath has now been detected in a fossil of “an emu-sized dinosaur that lived in what is now Mongolia during the Cretaceous period.”Keratin makes up hair and fingernails on us humans. It comes in two forms, alpha-keratin and a more durable beta-keratin. The researchers who dug up the “exceptionally preserved” specimen noticed the similarity of this dinosaur’s claw sheath to that of a living ostrich’s claw sheath, so they ran some tests to see if it could be original protein. Alison Moyer is a PhD candidate from North Carolina State who is now doing a postdoc at Drexel University.IHC [immunohistochemical] testing utilizes antibodies that react against a particular protein. If the protein is present, the antibodies bind to small regions of the protein and indicate where the protein is located in the tissue. Moyer used beta-keratin antibodies derived from modern bird feathers. In initial IHC testing, results were inconclusive, which led Moyer to look more closely at the specimen. She found an unusually high concentration of calcium in the fossil claw – much higher than would be found in claws from the living birds used in comparison or from the sediment surrounding the fossil. Theorizing that the calcium might be affecting results, Moyer removed the calcium and did further IHC testing on the claw sheath material.After the calcium was removed, the antibodies reacted much more strongly, indicating the presence of beta-keratin and preservation of original molecules.NC State is the home institution of Mary Schweitzer, who caught international attention in 2005 with discovery of soft tissue in a T. rex femur (see 3/24/05 and CBS 60 Minutes interview). Since then, many examples of original biological material have been found in creatures thought to have died tens or hundreds of millions of years ago. Most scientists had thought that biological tissues could not last a hundred thousand years, let alone millions. The authors say as much in an indirect way:Although conventional wisdom challenges the preservation of endogenous molecular remains, our combined data support the presence of original, proteinaceous material associated with this specimen, and add to the literature supporting molecular preservation in fossil materials across geological time.Those with access to the Royal Society journals can look up the paper for details. Schweitzer is listed as a co-author. The abstract says, “The fossil sheath was compared with that of extant birds, revealing similar morphology and microstructural organization.” It suggests that calcium acted as a preservative. The presence of hydrophobic amino acid residues cross-linked by disulfide bonds may have helped, they say. Unfortunately, the methods used precluded sequencing the protein to compare it with modern keratin.There are some who are not surprised to find soft tissue in fossils. Outspoken creationist Mark Armitage, who recently won a settlement against California State University for having fired him when he published a peer-reviewed paper on soft tissue in a Triceratops fossil he himself dug up and analyzed (10/04/16), believes the evidence not only refutes millions of years but supports the Biblical account of dinosaurs and all life.Breaking News 11/10/16: Another feathered dinosaur fossil has been reported from China. An exceptionally-preserved “mud dragon” (see Fox News) has its head arched back in the common “dinosaur death pose” indicative of suffocation. The open-access paper in Scientific Reports does not mention any soft-tissue preservation in this specimen of an oviraptorosaur, nor any impressions of feathers. Paleontologist Stephen Brusatte thinks it was a winged, flightless creature that got stuck in mud, but he was not present when the fossil was uncovered by workmen using dynamite in a building project. “Many of these discoveries are not found by professors or academic scientists with PhDs, but by farmers and workmen. This new discovery is a prime example of that.”We’re still waiting for the moyboys to tell the world how so much soft tissue can last for millions of years. This was not their prediction. It was a complete surprise. Now they are in rescue mode, trying to salvage their precious millions of years against the evidence of science and reason. Too much is at stake for them to admit defeat, so they have to ignore the implications of this powerful evidence. We’ll just keep putting it out there and letting common-sense people figure out what it means.Think about this, too: If the millions of years collapses for dinosaurs, it collapses for the story that birds evolved from dinosaurs. So what if this Mongolian dinosaur had similar proteins in its claws to extant birds? Big deal. Birds and dinosaurs were contemporaries, not ancestors or descendants by a Darwinian just-so story. Humans have keratin on their fingernails, too. Keratin is found in all kinds of reptiles, amphibians, birds and mammals. All it proves is that animals have a common designer.(Visited 69 times, 1 visits today)FacebookTwitterPinterestSave分享0

In a demo from the Sharepoint conference in Las Vegas, the Microsoft team showed how multiple people can edit an Excel document simultaneously. It is still not entirely clear how rich this feature set is in comparison to products from Google, eXpresso and EditGrid. Both eXpresso and EditGrid are stand alone applications.In comparison, Google’s spreadsheet product is as close as it gets to the Socialtext offering but lacks SocialCalc’s ability to keep track of revision histories.Bernard Lunn wrote last week that Google is missing the boat by not focusing on the spreadsheet market. Microsoft has not put tremendous energies into making its Excel spreadsheets more collaborative but it appears it is also a notch behind what Socialtext offers.According to Socialtext, SocialCalc is immediately available for trial and for current customers in the October Appliance release.

The age old DSLR debate is rekindled in this extensive video analysis.The Canon vs. Nikon debate has been an ongoing dialogue in the DSLR world for years. Just when you think one company is pulling ahead, a camera, lens, or accessory is released making the race wide open again. This uncertainty can be frustrating if you’ve already stocked up on lenses in another brand, so my approach has always been just stick with what I have.Generally speaking there is no bad decision when choosing between Canon or Nikon, but on a technical level there is some key differences that might be the tipping point when it comes to picking your next camera.The following video by photography expert Tony Northrup is an in-depth look at the key differences between the two leading DSLR manufacturers. Tony’s analysis is extensive and covers a variety of criteria, including:SensorsSharpnessDynamic RangeNoiseAuto FocusPriceLensesAccessoriesMarket Trends It’s important to take into account all of these things when picking your next camera. In the video Tony draws some very scientific information from DxO Mark. If you’re looking for some of the most extensive equipment reviews on the ‘net we highly recommend checking them out.Tony suggests that if you are planning on shooting video with your DSLR, you should consider a Panasonic camera. We couldn’t agree more. With the release of the GH4 Panasonic has changed the game for DSLR filmmakers (we’re currently Panasonic lovers).Do you use Canon or Nikon?Share in the comments below!
The Haryana government will build a ‘Bharat Mata’ temple at Kurukshetra as part of its attempts to develop the city as a tourist destination of international standards and a centre of religious faith, Chief Minister Manohar Lal Khattar said on Monday.“The ‘Bharat Mata’ temple will be constructed on five acres at a place between Jyotisar and Brahamsarovar. The plan is at the initial stage, and the modalities will be worked out soon,” he said at a press conference meant to announce the schedule for the International Gita Mahotsav-2019, being organized in Kurukshetra from November 23 to December 10. Uttrakhand is the partner State for the Gita Mahotsav, in which 15 countries are participating. “Delegations from the U.K., Mauritius, Australia and Canada are also visiting Kurukshetra for the event. Besides scholars of the universities in Haryana, those of foreign Universities and ambassadors of several countries will take part in the event,” the Chief Minister said. The Government of India had given its consent to the use of the logo of ‘Atulya Bharat’ (Incredible India) during the Gita Mahotsav.Mr. Khattar said the government was also mulling over a plan to offer plots, measuring 1,500-2000 square metres, in Kurukshetra on concessional rates to the States planning to construct ‘Bhawans’ for their pilgrims visiting the city.
