What's Past is Prologue.
The new year welcomes The Archealization Center (ArchC), a new way to study the distant past, and it's no wonder that the minds behind this innovative, multi-disciplinary research center at UC San Diego are both CARTA Members: Alysson R. Muotri, Professor of Pediatrics and Cellular & Molecular Medicine and Director of the Stem Cell Program; and Katerina Semendeferi, Professor of Anthropology and Director of the Laboratory for Human Comparative Neuroanatomy at UC San Diego. The ArchC extends Semendeferi's longtime focus on comparative neurobiology and combines it with Muotri's work growing human brain organoids, the latter of which allows for empirical modelling of social neurological conditions and brain evolution.
A new research article in Science (Feb 12, 2021) and featured in The New York Times (Feb 11, 2021) explores the differences between the genomes of diverse living human populations and archaic ones (e.g., the Neanderthals and Denisovans), producing "Neanderthalized" cerebral organoids that allow CARTA Members to grapple in new ways with basic questions regarding what makes us human.
