Growing up in the Chesapeake Bay watershed, 14-year-old George was always attentive to its aquatic life. When he learned the waters were acidifying, George wondered how it would affect aquatic organisms.
He decided to measure the effects of changing water acidity, salinity, and temperature on grass shrimp, Palaemonetes pugio, using their heart rates as a measure of their metabolic oxygen consumption. For his investigation, which is described at length in his essay, The Effects of pH, Salinity, and Water Temperature on Palaemonetes pugio, George received a2011 Young Naturalist Award.
There’s new evidence that dinosaurs, once thought to resemble scaly lizards, were in fact fluffy, colorful animals. In the video below, Curator Mark Norell, who is chair of the Museum’s Division of Paleontology and studies important feathered dinosaurs from Liaoning, China, shares his thoughts on the significance of two new studies about fossilized feathers reported in the current issue of Science magazine.
It’s a story more than a century in the making. Barnum Brown’s extraordinary fossil-hunting career—which took him from a frontier farm to the world’s top fossil sites and to the halls of the American Museum of Natural History—included the discovery of the first complete skeleton of the Tyrannosaurus rex.
The priceless fossil—the one used to describe the carnivorous species now synonymous with “dinosaur”—was displayed in the Museum for more than 30 years beginning in 1906. Then the story took a twist, which is traced in a recent NPR piece “Bone To Pick: First T. Rex Skeleton, Complete At Last.”
The wired world is a new frontier for psychologists and neuroscientists, who are starting to discover interesting impacts persistent technology use has on the brain. Navigating the latest science on the subject will be the focus of the Museum’s first fall adult course, The Wired Child: How 21st Century Technology Affects the Brain, which kicks off on Thursday, September 15, in the Sackler Educational Laboratory. Guest lecturers include Dr. Pamela Rutledge, media psychologist and expert blogger for Psychology Today, who will be leading the course on Thursday, October 6.
