Have I got a fish story for you. Any angler beginning a yarn like that usually ends up spinning a tall tale, an exaggeration or bald-faced lie. Michigan State University researchers, however, have demonstrated that anglers can produce accurate and complex environmental models similar to those of trained scientists. The study, led by graduate student

Findings from a 700,000-year-old fossil bone indicate that a close relative of the most abundant seabird species in the North Atlantic, the modern dovekie, or ‘little auk’, used to thrive in the Pacific Ocean and Japan. Seabirds are top predators in the marine ecosystem, and their distributions are shaped by numerous environmental factors in the

Wildfires in south eastern Brazil produce airborne pollution that worsens air quality in major cities such as Sao Paulo — cancelling out efforts to improve the urban environment and posing health risks to citizens, according to a new study. The planet is frequently affected by smoke from fires caused by humans and natural processes. Australia,

An illustration of two ensemble simulated tropical cyclone sets undergoing different timing for RI onset. For the early RI onset member, the minimal ventilation, undiluted clouds and moisture from the downshear quadrant are then wrapped inwards to the upshear left quadrant to form the deep convections (left-hand panel). For the late RI onset member, these

In order to determine the past magnetic field direction and intensity, the researchers dated and analyzed zircon crystals collected from sites in Australia. The zircons are about two-tenths of a millimeter and contain even smaller magnetic particles that lock in the magnetization of the earth at the time the zircons were formed. Here, a zircon
