Microscopy Today: Still-soft blood clots from six dinosaurs!
This is the show from Monday, April 12th, 2021
SUMMARY:
* Mark Armitage back on RSR: Real Science Radio host Bob Enyart interviews long-time friend Mark Armitage on his latest soft tissue discoveries published in a Cambridge University Press science journal, Microscopy Today. Bob welcomes Mark back to RSR after seven years during which time Armitage founded DSTRI, the Dinosaur Soft Tissue Research Institute. Here are three brief quotes from his paper on autofluorescence microscopy of dinosaur bones revealing blood clots. "dinosaur neurovascular bundles travel as a triad of veins, vessels, and nerve fibers, as in other vertebrates." And regarding the Schweitzer iron rescue device, "free iron was unavailable, at least in these... bones." And see all of our RSR programs with Mark listed at www.rsr.org/armitage.
And you may want to listen to the second of our two 2021 Armitage interviews...
Paleontology Breakthrough! Now, dinosaur nerve bundles!
* 29 Journals, 57 Papers: Mark Armitage is on back-to-back RSR episodes! To date, 29 peer-reviewed science journals have published a total of 57 dinosaur biomaterial discoveries including Nature, Science, Cretaceous Research, Current Biology, Geology, Paleontology, Vertebrate Paleontology, Nature Communications, Scientific Reports, PLoS ONE, Proceedings of the Royal Society B, and PNAS. The many dinosaur and other Mesozoic creatures yielding their original still-soft biological material include hadrosaur, titanosaur, the [ostrich-like] ornithomimosaur, Nodosaur, mosasaur, [bird-like] Anchiornis huxleyi, Triceratops, Lufengosaur, Archaeopteryx, and T. rex.
In fossils from dinosaur-layer and "deeper", i.e. believed older, strata, researchers have discovered flexible and transparent blood vessels and cartilage, red blood cells, starch, many various proteins including beta-keratin, the microtubule building block tubulin, collagen, mollusk shell glycoprotein and dino eggshell peptides and chelating ligands, chitin, the cytoskeleton components actin, tropomyosin, and the related motor protein myosin, and hemoglobin, bone maintenance osteocyte cells, pigment including melanosomes, clearly-seen chromosome-like structures within cell nucleus, DNA-related histone proteins, and powerful evidence for DNA including positive results from multiple double-helix tests including IP and DAPI on fossils from various dinosaurs. And now, thanks to microscopist Mark Armitage, dinosaur nerve bundles! So we invite you to enjoy today's interview with Mark, see his cover story paper in the latest issue of Microscopy Today, a Cambridge University Press journal, and check out all our related programs at www.rsr.org/armitage!

https://kgov.com/HPTWalt Brown's In the Beginning 8th Edition is OUT OF PRINT! Do you have a used copy you don't need? Here at Real Science Radio/BEL we've long been a source of information about the www.rsr.org/hydroplate theory and a great place to purchase Walt Brown resources. But now we're out. If you have a copy that you've already read, or that you know that you're not going to read, and would like to help us, we ask you to consider mailing your copy to BEL, 6126 Braun Court, Arvada CO 80004. (As of April 2021 new copies of Walt's book online are going for $300 to $370 each and used one for well over $100. But for our RSR listeners, and to keep ITB available for as reasonable a price as we can, around $120 each, we track sales of pre-owned books and offer them at our rsr.org/store.)
