SO ENDS this summary of the components of inflammation that contribute to both ageing and the chronic diseases of ageing. One can argue that trees drop their leaves in the autumn because they have accumulated considerable environmental and parasitic damage during the active summer period, and it is less difficult to start over and make a new leaf than to fix the numerous sites of cellular damage. https://www.nature.com/articles/s41574-018-0059-4 View in LinkedIn

ELECTRONIC TRIGGER. “When a photon hits a visual pigment, the chromophore changes from a 11-cis-retinal conformation to an all-trans-retinal, initiating the phototransduction cascade that leads to vision.” The nerve impulses then get chunked and reassembled by the brain into a cartoonized reality. https://lnkd.in/dsvuECMN View in LinkedIn

TESTING. “We test the hypothesis of the existence of an old globular cluster of anti-stars in the galactic halo by evaluating the flux of helium anti-nuclei in galactic cosmic rays.” https://lnkd.in/gDYri97U View in LinkedIn

THE FIRST PREDICTION. “At the end of the 1920s, Paul Dirac predicted the existence of antiparticles — that is new particles, which are opposite in sign of electric, baryonic, lepton and other charges of already known particles.” https://lnkd.in/gDYri97U View in LinkedIn

DIAGNOSTIC. “Antimatter is detected in cosmic rays.” https://lnkd.in/gDYri97U View in LinkedIn

ORIGIN OF ANTIMATTER. “According to the modern concepts it has three possible nature of origin: (1) Primordial antimatter. It could be created in the early Universe as the reflection of nonhomogeneous baryosynthesis, evolve in antimatter domains and now it can exist in the form of macroscopic antimatter objects like globular clusters of antimatter stars.” https://lnkd.in/gDYri97U View in LinkedIn

ORIGIN OF ANTIMATTER. “(2) Secondary antimatter. It is formed as a result of the collision of the nuclear component of cosmic rays with interstellar gas or with a supernova shell.” https://lnkd.in/gDYri97U View in LinkedIn

ORIGIN OF ANTIMATTER. “(3) Antimatter from exotic sources like evaporation of primordial black holes or the decay/annihilation of hypothetical particles of dark matter.” https://lnkd.in/gDYri97U View in LinkedIn

PRELIMINARY POSSIBILITIES. “I'll tell you: I begin always with a priori solutions. If anything happens to impress me, I have hundreds of hypotheses before I know the facts. I apply one after the other, till I find the one that covers the whole ground. But I am exceedingly careful and slow in printing.” (Charles Darwin). https://lnkd.in/g6B2FTy6 View in LinkedIn
