Ancient DNA has revolutionized the study of the human past, providing unprecedented insights into ancient migrations and interactions among populations. Central Asia, due to its geographic location between Europe and Asia, has seen experienced diverse human and hominin migrations, which have been a focus of genetic, archaeological, linguistic, and historical research. Ainash Childebayeva, professor at the University of Texas at Austin, discusses recent advances in population genetics which have revealed the complex ancestry of Central Asian groups, both modern and ancient. Significant progress has also been made in understanding the role of natural selection in shaping genetic variation across the region. Childebayeva presents recent developments in our knowledge of Central Asia’s genetic history, integrating findings from both modern and ancient genomic studies. Additionally, she highlights the selective pressures that have influenced the genomes of Central Asians through time, shedding light on the dynamic interplay between admixture, adaptation, and cultural change.

![Stem-Cell Aging and Pathways to Precancer Evolution
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=S1rgNFdB-Ek
Pre-cancer and cancer can begin when stressed blood-forming stem cells lose their normal controls. Catriona Jamieson, M.D., Ph.D., UC San Diego, explains how inflammation-linked editing enzymes, repetitive elements in the genome, and stem cell stress shape the progression from myeloproliferative neoplasms to acute myeloid leukemia. Jamieson examines how spaceflight accelerates stem cell aging, how some astronauts mobilize a resilient regenerative stem cell population, and how tumor organoids in space help reveal drug responses by activating the enzyme ADAR1. This work helps explain how cancer starts, why it can return, and how space-based research may speed the development of therapies that stop malignant stem cells before disease advances.

![Stem Cell Pathways Targeting Neurodegenerative Diseases
Stem cell science is reshaping treatment for complex disorders of the brain and spinal cord. Researchers develop cell based therapies to replace lost dopaminergic neurons in Parkinson’s disease, fill gaps across spinal cord injuries, and calm seizure networks in refractory epilepsy by restoring the balance of inhibition and excitation. Teams test immune cell therapies against Epstein Barr virus infected B cells in multiple sclerosis and collaborate to move treatments across the blood brain barrier to reach diseased cells. Clinicians combine imaging in the operating room, surgical tools, and research on biological age and the pace of aging to understand disease and guide treatment. Patient advocates describe challenges and hopes for better options, and contemporary art reflects on perception in digital and physical worlds. [Show ID: 40992]

![Inspiring Young People To Get Out in Nature
What’s the best way to get college students interested in nature? By getting them outside and teaching them valuable skills in wildlife conservation and habitat restoration. Associate Professor Laci Gerhart’s popular “Wild Davis” course does just that, and students who complete the course can earn California Naturalist Certification. [9/2025] [Show ID: 41070]
