"Penguins are 10 times older than humans and have been here for a
very, very long time," said Daniel Ksepka, Ph.D., a researcher at the National Evolutionary Synthesis Center (NESCent). Dr. Ksepka researches the
evolution of penguins and how they came to inhabit the African
Because penguins have been around for over 60 million
years, their fossil record is extensive. Fossils that Dr. Ksepka and his
colleagues have discovered provide clues about migration patterns and
the diversity of penguin species.
Dr. Ksepka goes into more depth
about how his research is piecing together the evolutionary puzzle of
penguins and other related bird species.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
