Young, top-notch scientists have a shot at recognition from the National Science Foundation. Each year the NSF names an early-career scientist to its Alan T. Waterman award. This year it named three. For what the award is all about and why the foundation has it, Tom spoke to program manager Gayle Pugh Lev.

Many other species communicate through sound, but only a very few — humans, elephants, bats, cetaceans, and a handful of bird species — learn new sounds in order to do so. Erich Jarvis has been shedding enormous light on the process of vocal learning, by studying birds and comparing them to humans. He argues that there is a particular mental circuit in the brains of parrots (for example) responsible for vocal learning, and that it corresponds to similar circuits in the human brain. This has implications for the development of intelligence and other important human characteristics.Support Mindscape on Patreon.Erich Jarvis received his Ph.D. in Animal Behavior and Molecular Neurobehavior from Rockefeller University. He is currently a professor in the Laboratory of Neurogenetics of Language at Rockefeller and an investigator at the Howard Hughes Medical Institute. Among his many awards are the Alan T.

This week we are speaking with Christopher Brinton and Mung Chiang, both experts on the subject of networks. In fact, the duo recently paired up to write a book called, The Power of Networks: Six Principles That Connect Our Lives. Mung Chiang is a Professor of Electrical Engineering at Princeton University. His research on networking received the 2013 Alan T. Waterman Award, the highest honor to US young scientists and engineers. He founded the Princeton EDGE Lab in 2009, which bridges the theory-practice gap in edge networking research by spanning from proofs to prototypes. Chiang is the Director of Keller Center for Innovations in Engineering Education at Princeton University and the inaugural Chairman of Princeton Entrepreneurship Council. Christopher Brinton is the Head of Advanced Research at Zoomi Inc. He received his PhD in Electrical Engineering from Princeton University. He is also an adjunct professor in the School of Engineering at The College of New Jersey.
