Ancient DNA Analysis Yields Unexpected Insights About Peoples of Central, South America

Harvard Medical School

The first high-quality ancient DNA data from Central and South America reveals two previously unknown genetic exchanges between North and South America, one representing a continent-wide population turnover Findings link the oldestCentral and South American samples with the Clovis culture, the first widespread archaeological culture of North America; however, this lineage disappeared within the last 9,000 years Analyses show shared ancestry between ancient Californians from the Channel Islands and groups that became widespread in the southern Peruvian Andes by at least 4,200 years ago

How Beatboxers Produce Sound: Using Real-Time MRI to Understand

Acoustical Society of America (ASA)

Beatboxing is a musical art form in which performers use their vocal tract to create percussive sounds, and a team of researchers is using real-time MRI to study the production of beatboxing sounds. Timothy Greer will describe their work showing how real-time MRI can characterize different beatboxing styles and how video signal processing can demystify the mechanics of artistic style. Greer will present the study at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
