Rare disease research is creating new paths for diagnosis, treatment, and broader medical discovery. Gene therapy can repair or replace faulty genes, and work on cystinosis has led to a stem cell platform now being applied to Danon disease, Sanfilippo syndrome C, Friedreich’s ataxia, and Alzheimer’s research. Funding programs support gene therapy, clinical trials, and new platform approaches for rare diseases. CAR-T cell research is also advancing treatment possibilities for pediatric brain tumors, including early results in children with DIPG and diffuse midline glioma. A patient advocate shares her daughter’s diagnostic odyssey and treatment for TUBB4A leukodystrophy. Together, these stories show why rare disease research matters beyond rarity.

![From Orbital Experiments to Curing Earthling Diseases: Advancing Neuroscience
A version of this video with audio description track is available here:
https://www.youtube.com/watch?v=JsFoFnqOVqQ
Brain aging and disease research can gain new insights from space. Aline M.A. Martins, Ph.D., UC San Diego, explains how neuroscience studies in space use brain organoids, proteomics, and single-cell analysis to understand cognition decline, space-induced neurosenescence, and disease-related changes. Martins examines molecular markers of senescence, mitochondrial impairment, and neuroinflammation in organoid models, including Rett syndrome, while also comparing how space affects organoids of different ages. She shows that space can accelerate aging-related changes and affect cell types differently, helping clarify how space biology may speed drug discovery and reveal biomarkers for disease. This work helps explain how space research can inform treatments on Earth and points toward faster preclinical testing and broader understanding of brain disease. Recorded on 03/02/2026.

![Reimagining T Cell Therapy: An Unconventional Path to Universal CAR-T Cells
Off-the-shelf immune cell therapies using engineered T cells represent an important direction in cancer treatment. Lili Yang, Ph.D., at UCLA develops an off-the-shelf platform based on invariant natural killer T (iNKT) cells generated from hematopoietic stem cells, often sourced from cord blood. Yang programs these stem cells with iNKT cell receptors, chimeric antigen receptors (CARs), and genes such as IL-15 to create pure, expandable iNKT products that recognize lipid antigens presented by non polymorphic CD1d molecules. These cells combine multiple killing mechanisms, infiltrate tissues, target tumor cells and immunosuppressive myeloid cells, and show reduced risk of graft versus host disease and cytokine release syndrome in preclinical models. Yang’s group tests this strategy in models of blood cancers and solid tumors, aiming to generate many therapeutic doses from a single donor. [3/2026] [Show ID: 40846]

![CARTA: Hominin Paleoneurology During the Stone Age - and Before! with Dean Falk
The distinct biology of the human brain, scaffolded by language and culture, allows ideas to be formed, named, shared, and accumulated across generations. Dean Falk, Professor of Anthropology, Florida State University, explains how paleoneurologists study the brains of human ancestors by producing endocasts from fossilized skulls and measuring cranial capacities. Dated skulls indicate brain size more than tripled in hominins during the Stone Age that began around 3.5 million years ago, while endocasts can also preserve traces of blood vessels and convolutions, even though sulci are often fragmentary and difficult to interpret. Falk describes how sulcal patterns differ most noticeably between great apes and humans in the lateral prefrontal cortex and in the parieto-occipital association cortices, and she addresses long-running debate about whether the lunate sulcus in evolving hominins marked the anterior border of primary visual cortex as it does in living monkeys and apes. Because few fossils exist from the earlier “Botanic Age,” she outlines how comparative primatology and evolutionary developmental biology can extend the study of brain evolution by considering brain development and locomotion, including bipedalism. She applies this extended paleoneurological synthesis with special attention to auditory entrainment and complex grammatical language. Recorded on 02/27/2026. [3/2026] [Show ID: 41328]

![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.
