See how our students contribute to solving important human needs. Series: "UC Davis News" [Science] [Show ID: 41052]

Coastal Santa Barbara is considered one of the most idyllic locations on the North American West Coast, but its beauty is frequently disrupted by fast-spreading, wind-driven wildfires. The east-west oriented Santa Ynez Mountains (SYM), rising abruptly over 1,000 meters from the coastal plain, create a distinct climatic environment by separating the cool, stable air over the Pacific from the much drier atmosphere of the Santa Ynez Valley. This topography leads to unique regional wind patterns, including the Sundowner winds, which occur along the southern slopes of the SYM. Leila Carvalho, Professor of Geography and a researcher at the Earth Research Institute at UC Santa Barbara, studies regional and large-scale climate variability and change, including monsoon dynamics, tropical-extratropical interactions, extreme precipitation and temperature events, mountain weather and climate, and regional modeling.

Stanley Chodorow, Emeritus Professor of History at UC San Diego, traces the evolution of food preservation, preparation, and production from ancient times to the modern era. He explores early methods such as drying, salting, and ice cellars, advances like iceboxes, refrigeration, and flash freezing, and innovations in cooking technology from open fires to gas and electric stoves. Chodorow examines the domestication of animals, the development of agriculture, and transformative tools like the wheeled plow and horse harness. He highlights the rise of industrialized food, refrigerated transport, and global trade in products such as sugar, chocolate, and processed foods. Concluding with the health impacts of dietary changes since the shift from hunter-gatherer to agricultural societies, he offers a sweeping view of how technology has shaped what—and how—we eat.

Sean Morrison, Ph.D., from the Children’s Medical Center Research Institute at UT Southwestern, investigates how stem cells function, regenerate, and interact with their surrounding environment in the bone marrow. His research reveals how leptin receptor-positive cells—key components of the bone marrow niche—regulate hematopoietic stem cell maintenance and regeneration, influence platelet production, and respond to physiological stress like pregnancy. Morrison uncovers a reciprocal relationship between these niche cells and peripheral nerves, showing that disrupting nerve signals impairs bone marrow recovery after chemotherapy or radiation. His work also links retrotransposon activation during pregnancy to increased red blood cell production, with implications for maternal health and transplant medicine.

Deepak Srivastava, MD, explores how cellular reprogramming offers new hope for treating heart disease. He highlights innovative strategies to regenerate damaged heart tissue by stimulating adult cardiomyocytes to divide and converting fibroblasts into heart-like cells. His team develops a nonviral delivery system using lipid nanoparticles and investigates the role of specific gene regulators in restoring heart function in animal models. Srivastava also discusses a potential oral therapy for aortic valve disease, driven by insights into cellular fate changes caused by NOTCH1 mutations and telomere shortening. Additionally, he reveals how trisomy 21 may trigger congenital heart defects by altering the identity of specialized heart cells. Through pioneering research in genetics and regenerative medicine, Srivastava demonstrates how understanding developmental biology can lead to transformative clinical advances.

Considered the godfather of A.I. music, UC Santa Cruz professor and composer David Cope, who died in May, 2025, developed the computer program EMI, or Experiments in Musical Intelligence, in the 1980s. It was one of the earliest computer algorithms used to generate classical music. This documentary film by UC Santa Cruz's Bob Giges looks at the impact of Cope's genius on the world of music.

Asteroids, often called “fossils of the solar system,” are remnants from its formation that offer clues about planetary origins and the potential beginnings of life. Dr. Neil Farber, Solar System Ambassador for NASA’s Jet Propulsion Laboratory, explains that some, known as near-Earth objects, pose impact risks—though large, dangerous collisions are rare—and NASA’s Near-Earth Object Surveyor mission aims to detect and track them to inform planetary defense strategies. Asteroids may also hold resources, such as metals or water, that could one day support space exploration, though current technology limits mining feasibility. Recent missions like OSIRIS-REx, Lucy, and Psyche are expanding our understanding of asteroid composition, history, and diversity, with findings including evidence of past water, amino acids, and nucleotide bases—key building blocks of life—raising intriguing questions about whether asteroids helped seed life on Earth.
