Smithsonian Secretary Wayne Clough, left, talks with Carlos Jaramillo, scientist at the Smithsonian Tropical Research Institute in Panama, at a research site near the Panama Canal. Jaramillo and his team are collecting and examining prehistoric fossils exposed during the recent widening of the Canal. To date, they have discovered the fossils of a 12-inch-tall [...] [...more]
A new study of marmosets, small South American monkeys, indicates that obesity may begin very early in life and suggests that marmosets may be a helpful model for obesity in humans. [...more]
Today, Marra is helping launch an Animal Mortality Monitoring Program in Africa intended to serve as an early warning system for emerging infectious diseases that can pass from animal populations into the human population. [...more]
Meet Rachel Page, a Smithsonian scientist in Panama who studies frog-eating bats (fringe-lipped bats), among other topics. Her current research focuses on learning and memory in neotropical bats, combining field studies with laboratory experiments to learn about predator cognition and its effects on the evolution of their prey.

Small monkey groups may win territorial disputes against larger groups because some members of the larger, invading groups avoid aggressive encounters. [...more]
Nearly 20 years after the Smithsonian Conservation Biology Institute became the first to produce an Eld’s deer fawn through artificial insemination, SCBI scientists have now contributed to the birth of the first Eld’s deer via in vitro fertilization. [...more]
A fragment of whale rib found in a North Carolina strip mine is offering scientists a rare glimpse at the interactions between prehistoric sharks and whales some 3- to 4- million years ago during the Pliocene. [...more]
This illustration by Carl Buell depicts Ocucajea picklingi (center) and Supayacetus muizoni (bottom), two ancient whales that lived off the Peruvian coast during the Eocene, between 56-34 million years ago. At top is an unnamed whale and the fossil penguin Perudyptes devriesi. Nicholas Pyenson, paleobiologist at the Smithsonian’s National Museum of Natural History, helped discover [...] [...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.
