Description:
SpaceWeatherNews on a California super-drought in the tree-ring record and on cosmic and geomagnetic effects on health.
Shevchenko writes that atmospheric muons break hydrogen bonds in water clusters and keep hydrolytic activity high enough for biochemistry. The paper says muon flux depends on the geomagnetic field, so magnetic storms can slow those processes and raise blood viscosity.
Hajiyeva and colleagues examined 42 children in Baku with congenital heart defects. Higher Kp tracked with lower platelet counts. Particulate pollution, including PM2.5, tracked with a different set of blood-count changes, and the two exposures were not correlated with each other.
A hypomagnetic-field preprint reports immune inflammation in brown adipose tissue and altered liver lipid metabolism, including more stored fat in liver droplets, when the geomagnetic field is shielded.
Jones and Williams reconstruct California summer soil moisture from tree rings back to the year 1100. They find 1579–1580 was by far the driest pair of years in that span, and that the instrumental record alone makes the 1580 severity look essentially impossible.
