By measuring patterns of species diversity in ecosystems that differ in age and human impact, insect ecologist Rosemary Gillespie says we can start to understand what features of a natural community provide stability in the face of intrusions driven by climate change and other threats from our own species.

Almost every child born in the United States undergoes state-mandated newborn screening within the first 48 hours of life. The blood collected from a "heel stick" helps test for 80 different serious but treatable genetic disorders. These disorders can be either genetic (passed down in families) or congenital (present at birth). But... what if we could go further? What if we could test a newborn's entire genetic sequence? Pediatric geneticist Ingrid Holm discusses the risks, benefits, costs and ethics of genomic sequencing in newborns.

Precision Pediatrics: The Case for Genomic Sequencing in Newborn Screening

We know Homo sapiens started in Africa, but we're uncertain about how they spread. Limited fossils and data have hindered our understanding. I'll discuss popular theories about our origins and how recent genetic data from Khoe-San people in southern Africa sheds light on this. Our research suggests a complex history, with population structures dating back to about 120,000-135,000 years ago. Early populations had connections, or gene flow, for hundreds of thousands of years. These "weakly structured stem" models explain genetic diversity that was once thought to come from other hominin species. Unlike previous ideas of interbreeding with archaic humans, our models predict that fossils from these populations should be genetically and physically similar. This variability in theories stems from not considering different possibilities, highlighting the importance of exploring various models to gain more accurate insights into our deep history.

Elsy Buitrago-Delgado, Ph.D., shares how spatial analysis of RNA distribution during early mouse embryogenesis suggests that the first cell fate choice is made at the 4-cell stage. She also discusses how notch signaling regulates cell fate choices during early human development. Series: "Stem Cell Channel" [Science] [Show ID: 38888]
