"Secular" trends in birth statistics from Minnesota uncovered as putative testable cosmic signatures. Shown are the residuals from second-order polynomial fit. Period (τ), double amplitude (2A) and MESOR (chronome-adjusted mean value) assessed by nonlinear least squares, listed with 95% confidence limits. Birth weight in Minnesota undergoes changes that could be signatures during evolution and/or contemporaneously of the cycle in sunspot bipolarity (N of babies: 2,136,745 = 1,097,283 boys and 1,039,462 girls).
