For three years—2001, 2002 and 2008—on Teopa Beach in Jalisco, Mexico, researchers examined the shell, neck and flippers of female turtles that had come out onto the beach to nest, collecting and carefully documenting all the organisms—known as epibionts—they found. [...more]
With the gift of a Siemens SOMATOM Emotion 6 CT scanner from Siemens Healthcare, Smithsonian researchers are acquiring information about museum objects that is fundamentally changing the way scientists examine specimens [...more]
In a new study researchers from the Smithsonian Conservation Biology Institute’s Center for Conservation and Evolutionary Genetics used DNA from coyote scat (feces) to trace the route that led some of the animals to colonize in Northern Virginia. [...more]
Adding wings to a robotic bug helped it run faster and better, but was it enough to achieve takeoff? [...more]
It is one of the rarest shrubs in the southeastern United States but for scientists trying to save it, the critically endangered Michaux’s sumac (Rhus michauxii) is not cooperating. [...more]
Scientists from the Smithsonian Migratory Bird Center have found that fledgling catbirds living in the suburbs are extremely vulnerable. Almost 80 percent are killed by predators before they reach adulthood. Nearly half of the deaths are connected to domestic cats. The team studied catbird nests in 3 suburban neighborhoods in Maryland: Spring Park, Opal Daniels Park, and Bethesda. Learn more about this 2011 study by clicking here.
