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 dement...

Bias in health AI can shape who gets care, how fairly risk is measured, and whether automation helps or harms patients. Karandeep Singh, M.D., M.M.S.C. explains that predictive AI can reflect historical, representation, measurement, learning, evaluation, and deployment bias, especially when models are trained on limited populations or use flawed proxies for illness and access to care. Singh also d...

AI in healthcare raises urgent questions about bias, privacy, and power. Safiya U. Noble, Ph. D., examines how AI systems can reproduce social and racial inequities when they rely on incomplete data, hidden assumptions, and proxies such as healthcare spending. Noble points to problems in search engines, image generation, facial recognition, and medical algorithms, including cases where systems mis...

Alzheimer’s disease unfolds over many years through a complex interplay of amyloid, tau, genetics, lipid biology, and the brain’s immune response. John Hardy, Ph. D., explains how rare inherited forms of Alzheimer’s disease helped shape current thinking about how the disease begins, then connects those discoveries to broader questions about late onset disease and why it develops differently across...

Seizures caused by epilepsy can have a dramatic impact on one's quality of life. For Nolan, his seizures cost him everyday independence, including the ability to drive. When he decided to have surgery, he chose awake brain surgery led by Dr. Edward Chang, a neurosurgeon at UCSF. During surgery, Nolan speaks and responds as the medical team carefully maps the language regions of his brain — guiding...

Cognitive resilience depends on how the brain responds to environment, aging, and inflammation. J. Tiago Gonçalves, Ph. D., studies the hippocampus to examine how spatial memory is shaped by factors such as cognitive enrichment, exercise, social interaction, disease, and age. Gonçalves explains how adult neurogenesis and microglia help support the brain’s ability to encode information, and how dis...

Alpha Clinics in California accelerate the development of regenerative medicine therapies that use cells and genes to treat serious diseases. Patient advocate Tara Radcliffe Ghiglieri shares lived experience with gene therapy, while Sheldon Morris, M.D., M.P.H., Mehrdad Abedi, M.D., Daniela A. Bota, M.D., Ph. D., Catriona Jamieson, M.D., Ph. D., Michael Lewis, M.D., Mark Walters, M.D., and Leo D....

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...

How fast are you really aging, and what could that mean for brain health? Aladdin H. Shadyab, Ph. D., explores the gap between chronological age and biological age, and why that difference matters for long-term health. Shadyab describes tools that use information from blood to estimate how quickly the body is aging, including approaches that look beyond the body as a whole to consider aging in spe...

The postpartum period is a major transition that reshapes the body, emotions, and daily life all at once. Julia Cormano, MD, FACOG presents a clear overview of recovery after delivery, explaining common physical changes, expected discomforts, and practical ways to support healing. Cormano emphasizes that experiences vary, and that understanding what is typical can reduce stress and help families f...

RNA binding proteins help cells control how genetic information becomes working proteins, and Gene Yeo, Ph. D., M.B.A., at UC San Diego investigates how their disruption contributes to neurodegenerative disease. Yeo focuses on ALS, a severe motor neuron disease in which the RNA binding protein TDP-43 moves from the nucleus to the cytoplasm, loses normal RNA processing functions, and triggers crypt...

Aging is the leading risk factor for cancer, Alzheimer’s, diabetes, and heart disease, and Robert A.J. Signer, Ph. D., studies how aging stem cells shape pre-cancer and healthspan. As deputy director of the Sanford Stem Cell Discovery Center, Signer focuses on rare blood-forming stem cells that self-renew, generate all blood and immune cells, and normally sustain more than 35 trillion blood cells,...
