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.

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.

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. Jamison 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.

Space healthcare depends on connected health data that can follow people wherever care happens. Peter DeVault, Epic, explains how electronic health record tools built for hospitals, labs, and patients can also support healthcare in space. DeVault describes patient-facing tools like MyChart, interoperability across health systems, structured genomics and pharmacogenomics in the patient record, and Cosmos, Epic's patient data aggregation platform with about 300 million longitudinal records. He also examines AI capabilities that can generate possible future health scenarios and expand to telemetry and molecular data collected before, during, and after a mission. This work helps explain how records, data sharing, and predictive tools could support astronaut health and resilience and why those capabilities may be necessary for the future of space medicine.

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.

Youth mental health is increasingly shaped by how teens use AI for emotional support outside clinical care. Cinnamon Bloss, Ph.D., UC San Diego, explains how growing use of conversational AI reflects major gaps in care and changing preferences for support. Bloss examines the appeal of AI's accessibility and nonjudgmental responses, concerns about replacing human connection, and the need to monitor harms, helping clarify how AI fits into a fast-changing mental health landscape. She also points to the importance of listening to young people, improving AI credibility and transparency, expanding safety and privacy discussions in schools, and preparing clinicians and online safety workers for this new reality. This work helps explain why teens are turning to AI and points toward a more thoughtful balance between safety and access to mental health support.

Brain aging and neurological disease are hard to study because living human brain tissue is difficult to access. Alysson Muotri, Ph.D., UC San Diego, explains how brain organoids sent to space can model accelerated aging, reveal changes in neural networks, and help test potential treatments for brain disorders. Muotri examines space-induced senescence, fragmented network activity linked to dementia and Alzheimer's patterns, and Rett syndrome findings showing inflammation tied to endogenous retroviruses and response to antiretroviral drugs in preclinical models. He also explores using brain organoids in space to screen neuroprotective compounds, including candidates identified from Amazon plants. This work helps explain how space biology can speed research on autism, Rett syndrome, Alzheimer's disease, and other neurological conditions, and points toward new ways to test therapies on Earth.
