Background: Male reproductive disorders that are of interest from an environmental point of view include sexual dysfunction, infertility, cryptorchidism, hypospadias and testicular cancer. Several reports suggest declining sperm counts and increase of these reproductive disorders in some areas during some time periods past 50 years. Materials and Methods: Except for testicular cancer this evide...

Structural biology at hard X-ray free-electron lasers is evolving rapidly beyond the experimental styles long established at storage ring sources. The comprehensive review by John Spence [IUCrJ (2017), 4, 322-339] provides magisterial oversight of recent developments.

Geophysical applications of radar interferometry to measure changes in the Earth's surface have exploded in the early 1990s. This new geodetic technique calculates the interference pattern caused by the difference in phase between two images acquired by a spaceborne synthetic aperture radar at two distinct times. The resulting interferogram is a contour map of the change in distance between the...

Elucidating the statistical properties of extreme meteo-climatic events and capturing physical processes responsible for their occurrence are key steps improving our understanding climate variability change better evaluating associated hazards. It has recently become apparent that large deviation theory is very useful investigating persistent events, specifically, flexibly estimating long retur...
