From Catherine Offord at the at The Scientist: In one recent project, for example, Schroeter and her advisor Mary Schweitzer extracted and analyzed collagen peptides from just 200 mg of an 80-million-year-old fossil of a Cretaceous-era herbivore, Brachylophosaurus canadensis, excavated in Montana. The amino acid sequences of those peptides, published last year, placed the dinosaur on […]
Can protein folding complexity be formed by stochastic processes? With 14 intermediate steps? JILA Team Discovers Many New Twists in Protein Folding Biophysicists at JILA have measured protein folding in more detail than ever before, revealing behavior that is surprisingly more complex than previously known. . . . They fold into three-dimensional shapes that determine […]
“The grammar of DNA might be even more sophisticated than we imagined . . .It could be that all codons could be start codons”
A frequently made claim in the scientific literature is that protein domains can be readily recombined to form novel folds. In Darwin’s Doubt, Stephen Meyer addresses this subject in detail (see Chapter 11). Over the course of this article, I want to briefly expand on what was said there. Defining Our Terms Before going on, it […]
What say we copyright the expression “than previously thought”?
