IMPACT ON VITAMIN D. “One of the effects of UVB radiation is that it acts on 7-dehydrocholesterol in cells of the superficial integument of terrestrial animals to make, by a photochemical reaction, the pre-hormone, cholecalciferol.” https://lnkd.in/e5hTuW74 View in LinkedIn

ULTRAVIOLET BLOCKER. “In the steady atmospheric state of the present-day era, the intensity of UV light reaching the Earth's surface is attenuated by ozone. However, the UVB-absorbing power of SO2 is 2·5 times greater than that of ozone.” https://lnkd.in/e5hTuW74 View in LinkedIn

“PLATO concludes that the body is composed of the same elements as the universe, and that, finally, the universe is ruled by mind.” (Page 104). https://lnkd.in/eq8pQ57b View in LinkedIn

SULFUR DIOXIDE ANOMALY. “One biologically significant property of stratospheric SO2 is that it strongly absorbs solar UV light in the UVB wavelength range of 290 to 320 nm.” https://lnkd.in/e5hTuW74 View in LinkedIn

THE ORDER OF MATTER. “In CDM cosmologies structure forms hierarchically: small halos (on average) form earlier, and then larger halos form via mergers and accretion. Subhalos are reduced in mass, or destroyed, by tidal stripping as they orbit within larger halos.” (CDM = Cold Dark MatterCold dark matter). https://lnkd.in/e6ifiQMn View in LinkedIn

MISPLACED CONCRETENESS. “Reality consists of a hierarchy of intertwined processes. There are very few explicitly processual theories in biology today. As a practising biologist, I’ve always found this utterly baffling and disappointing. We remain strangely fixated on explanation in terms of static unchanging entities.” (Foreword, by Johannes Jaeger). https://lnkd.in/evBZWZaE View in LinkedIn

SO ENDS this Fragment. Dr Fraser, in private correspondence with me revealed the following. “I suspect that few palaeontologists would browse a nutrition journal and those that I have spoken to are mystified by the idea of biological mechanisms for species extinction.” In other words, this very credible and testable hypothesis has been overlooked. https://lnkd.in/e5hTuW74 View in LinkedIn

LAG. “DM self-interactions transfer momentum between the cluster halos, so they lag behind the collisionless galaxies, leading to an offset between the DM and galaxies. Merging clusters also lead to constraints from the cluster surviving the merger.” (DM = dark matter). https://lnkd.in/e6ifiQMn View in LinkedIn
