Model protein Created 2025-06-17 Updated 2025-07-16
Ciro Santilli defines a "model protein" as a protein which has been significantly used in the history of protein science, in analogy to the term model organism.
Key characteristics of model proteins include:
- they are easy to obtain and are stable
- they are important to medical applications
- they are small and easier to understand for early studies
Important model proteins include:
- insulin: as a peptide hormone, this was small. Also it was useful and widely available even at pharmacies, The Eighth Day of Creation says you could get it a Boots, a major British pharmacy chain, and as such was a natural choice for the first sequencing by Frederick Sanger published in 1951
- hemoglobin
- keratin

Radio astronomy is cool because it revealed:The 1974 Nobel Prize in Physics was awarded for pioneering radio astronomy from the late 40s onwards done at the University of Cambridge which was an epicenter of early research in that area, leading to the creation of the Mullard Radio Astronomy Observatory in 1958.
- some very interesting new types of astronomical objects that were not as noticeable in the visible spectrum notably:
- quasars: quasars are extremely redshifted, which means by Hubble's law that they are very far from Earth, so the fact that we could see them at all meant they must have produced immense amounts of light
- pulsars: scientists thought they had found extraterrestrial life when they saw these regularly pulsating signal sources!
- cosmic microwave background which is a major evidence for the Big Bang
- radio wavelengths penetrate Earth's atmosphere better than the visible spectrum making it easier to make ground-based observations

A Structure for Deoxyribose Nucleic Acid Created 2025-06-12 Updated 2025-07-16
Starting line:The Eighth Day of Creation explains the "salt" part as that was the usual way to prepare DNA for X-ray crystallography, where something binds with the phosphate groups of DNA
We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A,). This structure has novel features which are of considerable biological interest.
The paper then shoots down other previously devised helical structures, notably some containing 3 strands or phosphate on the inside.
Then they briefly describe their structure, and promise more details on future articles. This was mostly a short one-page priority note.
Then they drop their shell bomb conclusion:
It has not es~aped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.
Both Wilkins and Rosalind Franklin are acknowledged at the end.

NP-hard cryptosystem Created 2025-06-12 Updated 2025-07-16
This is natural question because both integer factorization and discrete logarithm are the basis for the most popular public-key cryptography systems as of 2020 (RSA and Diffie-Hellman key exchange respectively), and both are NP-intermediate. Why not use something more provenly hard?
