4 Ways UC San Diego Research Is Changing the Future of Health

Health care is changing - not just in the way diseases are treated, but in how they're detected and, increasingly, prevented.

At the University of California San Diego, researchers are helping drive that shift, bringing together expertise across disciplines to move discoveries more quickly from the lab to real-world care.

What does that look like in practice? A patient gets faster answers after a biopsy. An older adult stays stronger and more independent. Communities face fewer risks from disease. These efforts point to a shift in medicine toward earlier detection, more precise treatment and new ways of preventing illness altogether.

Here are four ways that work is already taking shape across campus:

1. Delivering faster, more precise cancer care

For most people, cancer is not an abstract idea. It is part of their lives, or the lives of those close to them. And for many, the initial diagnosis is followed by a stretch of waiting.

After a biopsy, the next step is often genomic testing, which looks at a tumor's DNA to help determine the best course of treatment. Results can take weeks and sometimes fail to produce usable answers at all. In the meantime, decisions are on hold, and the uncertainty can be as difficult as the diagnosis itself.

At UC San Diego, researchers are working to shorten that window. Teams across the School of Medicine, Jacobs School of Engineering and Moores Cancer Center are developing ways to get answers from the same biopsy slide, without the added step of genomic testing. Using artificial intelligence, they can read those slides and, in a matter of minutes, begin to identify patterns that point to how a tumor is likely to respond to treatment.

One of those tools, known as DeepHRD, focuses on breast and ovarian cancers, where those signals can help guide early treatment decisions. Instead of waiting for additional testing - or repeating it when results are inconclusive - clinicians can start with a clearer sense of direction. For patients, that can mean less time waiting in uncertainty.

2. Rethinking how we age

Much research on aging happens in controlled settings like clinics and labs. But aging itself unfolds day to day, in the spaces where people live.

For many older adults, a fall is often the moment when aging becomes most visible. Falls can mark a turning point, often leading to injury, loss of independence and a cascade of health challenges that can be difficult to reverse. As more Americans than ever reach this stage of life, preventing those moments - and understanding what helps people recover from them - has become an urgent focus of research.

At Belmont Village Senior Living in La Jolla, that gap is beginning to close. Inside a sixth-floor apartment known as the Living Lab, researchers from the Sam and Rose Stein Institute for Research on Aging work alongside residents, turning everyday routines into opportunities to study what helps people stay strong, resilient and connected as they age.

In the Living Lab, research becomes part of daily life. Residents take part in interviews, complete cognitive and physical assessments and help test new ideas as they're being developed. In many cases, they also help shape what those ideas become, offering input based on their own experiences. The work spans more than physical health, including questions about cognition and how practices like mindfulness meditation may influence the aging brain.

That dynamic is already influencing how interventions are designed. In one recent project, residents tested a 12-week fall prevention program focused on improving strength, posture and balance. Working closely with participants allowed researchers to refine the program in real time and begin thinking about how it could extend beyond a single community.

At the same time, researchers in the School of Medicine are examining a related question: why some older adults recover and maintain independence after a stress event like a fall-related injury, while others decline. Through a multi-institutional effort, scientists are studying the biological markers of resilience, or what allows the body to recover after stress. The goal is to understand why people with similar health profiles can follow very different paths, and how those differences might be addressed earlier.

3. Tackling disease at the source

In the United States, a mosquito bite is often an afterthought - a quick swat, a small itch. A minor inconvenience at most. But in many parts of the world, one bite can carry diseases that can change the course of a life.

Malaria, dengue and other mosquito-borne illnesses continue to affect hundreds of millions of people each year, placing a heavy burden on families and health systems. Efforts to control these diseases have long relied on bed nets, insecticides and medication, tools that have saved lives but are becoming less effective in some regions as mosquitoes adapt.

On campus, a different approach is taking shape. Across several labs in the School of Biological Sciences, the focus is on changing how mosquitoes interact with and carry disease.

One line of research aims to reduce mosquito populations over time by influencing how future generations are produced, a strategy designed to lower risk in the communities most affected - particularly for children, who account for the majority of malaria-related deaths. Another targets the transmission process itself. In a recent study, researchers identified a small genetic change that prevents the malaria parasite from reaching the mosquito's salivary glands, which are necessary for passing the infection to humans. The mosquito can still bite. It just can't transmit the disease.

Related work is taking a similar aim with other illnesses. In one effort, mosquitoes have been engineered to produce molecules that neutralize the dengue virus inside the insect, effectively blocking its ability to spread.

4. Unlocking the science of human milk

What's actually in human milk, and how might its benefits extend beyond infancy?

Here, researchers are working to answer those questions. The Human Milk Institute, believed to be the first research institute of its kind in the world, brings together scientists, physicians and educators to study human milk, from its molecular composition to its broader role in health and disease.

What they're studying is far more complex than it might seem. Human milk is a living system, made up of molecules, antibodies, cells and bacteria that shape early development and long-term health. It has been linked to outcomes ranging from protection against infection in infancy to risks for chronic conditions later in life.

Scientists are now looking more closely at how those components might be used beyond infancy, from improving outcomes for premature babies to informing therapies for conditions like cardiovascular disease and cancer. They are also examining how human milk is influenced by medications, environmental exposures and infectious diseases, including work during the COVID-19 pandemic that helped confirm the virus is not transmitted through breast milk.

That work extends beyond the lab. Through the UC Health Milk Bank, operated by UC San Diego Health, donor milk supports thousands of infants each year, particularly those born prematurely or with medical complications, while also contributing to ongoing research that helps guide care.

Human milk has been part of human life as long as humans have existed. Now, our researchers are helping to build a clearer understanding of just how much it can do.
