"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

penguins and other related bird species.

PODCASTS: From Balloons to Space Stations: Studying Cosmic Rays
Cosmic rays have mysterious qualities about them that scientists continue to research in order to better understand their origins and composition. Dr. Eun-Suk Seo, a professor of physics at the University of Maryland, and her colleagues, fly enormous balloons as large as a football stadium and a volume of 40-million-cubic feet for extended periods over Antarctica to study particles coming from cosmic rays before they break up in the atmosphere.
