Issues concerning the sedimentology, the science of studying rock layers, are presented. Issues include the geological worldview of long time-horizons and slow processes were mountain erosion is compressed into new rock. Lead fumes find their way into these sediments.

issues concerning research in the effects of elevation and the body's physiological limits are presented. Issues include military, space and mountaineering applications& ;to& ;science fiction.

The Antarctic region has long been an area to be avoided, not one that would support extensive research. However, it has become feasible for researchers not only to exist, but to be reasonably comfortable in the region, and those in such fields as geology, astronomy and meteorology are becoming interested.

This article explores the devastation caused by the eruption of Mt. St. Helens on May 18, 1980, and the subsequent surprising aspects of the healing of the affected Pacific Northwest area.

The article offers information on the U.S. National Aeronautics and Space Administration's (NASA) Double Asteroid Redirection Test (DART) spacecraft that is designed to approach the binary asteroid Dimorphos, which is scheduled to occur on September 26, 2022, to test whether it is possible to deflect an asteroid from its path by smashing a spacecraft into it. Topics covered include the scientific objectives of DART, and images that DART is expected to return.

If you compete in marathons, the time will come when you can't make it to your goal race. Maybe you get the flu. Maybe a storm scrambles transportation, preventing you [...]

The article informs that U.S. National Aeronautics & Space Administration (NASA) successful InSight mission to send a craft to another planet. It is noted that InSight was conceived as a billion-dollar project to put a seismometer on the surface of Mars to use the Red Planet's occasional marsquakes to probe its interior. It is noted that solar panels of InSight had been getting dusty, and dust devils had come along to scrub them clean for the solar-powered Spirit and Opportunity rovers.

Several years ago a team of Japanese researchers put a dozen collegeaged men on exercise bicycles for four to six weeks of training. Following each workout, the research subjects stuck [...]

In the early 1970s, University of Oregon runners did a workout in which they alternated 30-second and 40-second 200s for as long as they could handle it. 'The record was [...]

Proposition 65, an environmental initiative passed by the California government in 1986, has become effective by exposing 500 chemicals which have harmful side-effects and by initiating changes in various processes adopted by companies. During the early years, Proposition 65 was limited to alcoholic beverages, gasoline and industrial toxins and had to be satisfied with ineffective warnings. A slight change in the proposition's rules made stalling by companies counterproductive, encouraging them to abide by the guidelines offered and to reform their products.

The article focuses on European space telescope Gaia uses the Earth's orbit to provide a long baseline to triangulate on stars and relies on making very accurate measurements of positions. It mentions that Gaia data suggest that the first of galaxy collisions might have been responsible for the birth of the Sun.

At a meeting in Rockville, MD, on Aug. 2, an expert panel convened by AOAC International approved 'First Action' official methods for two more chemicals of interest to the supplement [...]

The article discusses Beijing Winter Olympic Games 2022.
