![CARTA: The Evolution of the Human Brain through Shifts in Gene Regulation
A fundamental question in biology is: how did humans acquire their unique characteristics? What allows us to stand upright, while our primate ancestors walked on all fours? What brain alterations drove our increased intelligence and allowed us to perceive our own mortality? One of the mechanisms that has been hypothesized to be involved is changes in gene expression elicited by nucleotide alterations in non-coding regions of the human genome. Miles Wilkinson, a professor in the Department of Obstetrics, Gynecology, and Reproductive Sciences at UC, San Diego, discusses a class of DNA sequences hypothesized to have this role. These human accelerated regions (HARs) are segments of DNA that exhibit 3 characteristics that—together—make them prime candidates for specifying human-specific traits by altering patterns of gene expression. First, HARs have rapidly changed in sequence specifically in the human lineage. Second, HARs are highly conserved in sequence, indicating they that must have been selected for the ability to confer one or more function in higher organisms. Third, the vast majority of HARs are in the non-coding portion of animal genomes, indicating that most are likely to have a regulatory function. Recorded on 02/27/2026. [Show ID: 41300]

![How Machine Learning Improves Algorithms with Ellen Vitercik
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v Z1WDEuT6lU
Hard optimization problems often look impossible through worst-case analysis, but real-world problems can contain structure that helps algorithms work faster. Ellen Vitercik, Ph.D., of Stanford University explains how machine learning can improve algorithm design for NP-hard optimization problems while preserving the formal guarantees that make solvers useful. She discusses beyond worst-case analysis, problem-specific heuristics, and the gap between tools that perform well in practice and methods that prove optimality. Vitercik also describes research on LLM reasoning using data structure tasks, where answers can be checked programmatically and failures reveal when models rely on pattern matching rather than true generalization. Her work helps clarify how AI may support stronger algorithms, more useful benchmarks, and more reliable reasoning systems. [Show ID: 41179]

FAQ
Q: What is beyond worst-case analysis?
A: Beyond worst-case analysis looks at hard problems in a more practical way than standard worst-case analysis. Vitercik explains that many real-world optimization problems are NP-hard, but they may share useful structure that algorithms can learn and use to solve them faster.
Q: How can machine learning improve algorithm design?
A: Machine learning can help identify patterns or choose heuristics that make hard optimization problems easier to solve in practice. Vitercik emphasizes that a central challenge is using these tools while preserving the formal optimality guarantees that make optimization solvers valuable.
Q: How do researchers test whether LLMs are reasoning or pattern matching?
A: Vitercik describes using algorithmic and data structure tasks because the correct answers can be checked programmatically. When models succeed on familiar-looking examples but fail on unusual or non-uniform cases, it suggests they may be relying on pattern matching rather than general reasoning.

![CARTA: Human Microbiome Evolution with Christina Warinner
Humans have a deep and complex relationship with microbes. Beyond disease, microbes also profoundly shape human health and behavior through their activity in the microbiome and their diverse roles in food and cuisine. And yet we know very little about the origin, evolution, or ecology of the trillions of microorganisms that call us home. Christina Warinner of Harvard University discusses recent advances in genomic and proteomic technologies that are opening up dramatic new opportunities to investigate the complex and diverse microbial communities that have long inhabited our human bodies and our food systems - both in sickness and in health. From infectious disease to the microbiome, microbes are the invisible and often overlooked figures that have profoundly shaped human culture and influenced the course of human history. Warinner focuses on the long arc of human-microbial relationships preserved by ancient DNA over the past 100,000 years, and explores how emerging research on pathogen evolution and the recent loss of commensal microbes is changing how we understand human health – both today and in the past.

![Blood Stem Cells, Aging, and Inflammation
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=kfAKpWWLmN4
Hematopoietic stem cells make blood across the lifespan, but they do not all behave the same way. Stephanie Xie, Ph.D., Scientist at Princess Margaret Cancer Centre, University of Toronto, examines how these rare cells self-renew, differentiate, and respond to inflammatory stress, asking whether differences in the stem cell pool help explain why aging affects people so differently. Xie identifies two hematopoietic stem cell subsets, including one that retains inflammatory memory after stress recovery, and connects this state to aging, clonal hematopoiesis, sickle cell disease, post-COVID recovery, and mortality risk markers in blood. Her research also raises questions about whether targeting the inflammatory environment, including through GLP-1 receptor agonists or metformin, could help mitigate clonal hematopoiesis. Understanding these patterns could clarify how inflammation shapes blood production, cancer risk, and immune health over time. [7/2026] [Show ID: 41406]
