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

Sand crabs, a key species in beach ecosystems, were found to have increased adult mortality and decreased reproductive success when exposed to plastic microfibers, according to a new Portland State University study. Dorothy Horn, a Ph.D. candidate in PSU’s Earth, Environment and Society program, examined the effects of exposure to microfibers on adult mortality, reproductive
