Part of the ancient archaeological site of Tiwanaku, Bolivia, believed by Incans to be where the world was created has been reconstructed using 3-D printed models of fragments of an ancient building. The results are presented in a study published in the open access journal Heritage Science.
A new study suggests reducing the number of fishing days in a season doesn't reduce catch as much as some would predict. The publication, Compression and relaxation of fishing effort in response to changes in length of fishing season for red snapper (Lutjanus campechanus) in the northern Gulf of Mexico, was released by NOAA in the November 2018 National Fishery Bulletin.
Kids lying on their backs in a grassy field might scan the clouds for images—perhaps a fluffy bunny here and a fiery dragon over there. Often, atmospheric scientists do the opposite—they search data images for the clouds as part of their research to understand Earth systems.
New research suggests that populations of the Northern Cardinal —one of the most ubiquitous backyard birds in the United States— are undergoing speciation in two adjacent deserts. This study, which analyzed genetics and vocal behavior, gives clues about the early steps in bird speciation. The study is published in the journal Ecology and Evolution.
Speed limits set only five miles per hour below engineering recommendations produce a statistically significant decrease in total, fatal and injury crashes, and property-damage-only crashes, according to a group of Penn State researchers.
