Rx One Health in Ireland is officially underway!

This year’s cohort has arrived in Dublin, where 31 participants representing 19 countries and expertise spanning human health, animal health, environmental health, and the social sciences have come together for 2 weeks of immersive One Health training.

Hosted by our partners at University College Dublin, the course provides a unique opportunity for participants to learn alongside one another, exchange perspectives across disciplines and borders, and explore real-world approaches to complex health challenges that connect people, animals, and the environment.

We look forward to the connections, conversations, and collaborations that will emerge over the coming weeks as we work together to advance One Health for all.

Happy ! At the One Health Institute, we're proud to support the next generation of One Health leaders tackling environmental health challenges with opportunities for student funding, training, and field-based learning. Our latest collaboration is with UC Nature & Sentinel Sites for the 2026 Nature Summer Research Fellowship and we look forward to sharing updates from the selected students later this year!

We're committed to advancing environmental health and empowering future leaders to address the impacts of climate change through a One Health approach.

Accessible veterinary care is in action!

In late March, volunteers from the UC Davis Weill School of Veterinary Medicine traveled to Covelo, California for another weekend of compassionate, community-centered veterinary care through the Covelo Clinic. Entirely volunteer-run, the clinic brings together veterinarians, veterinary students, ve...

As highly pathogenic avian influenza (H5N1) continues impacting wildlife globally, some of the world’s most endangered seabirds, including albatrosses and petrels, face growing risk.

Spearheaded by Latin America Program scientist Dr. Ralph Vanstreels, a new publication in Biodiversity Data Journal introduces the first openly accessible global database focused specifically on H5N1 outbreaks in these species.

Developed through the Agreement on the Conservation of Albatrosses and Petrels (ACAP), this resource helps researchers, governments, conservation teams, and other decision-makers around the world track and respond to the rapidly evolving impacts of H5N1 across remote marine ecosystems.

This , we’re highlighting how collaboration and innovation needed to help protect some of the world’s most vulnerable wildlife.

For years, researchers faced a difficult challenge with critically endangered right whales: how do we gather the movement and habitat data needed to protect them from threats like entanglement, vessel strikes, and climate-driven ecosystem change without compromising the wellbeing of the animals themselves?

Through a long-term international collaboration supported by NOAA and the U.S. Office of Naval Research, scientists and veterinarians worked to develop less invasive satellite tags designed specifically with whale welfare in mind. Our field veterinarian Dr. Marcela Uhart leads the animal health and welfare aspects of the project, helping ensure the highest standards of research ethics while advancing critical conservation science.

The resulting “blubber-only” tag design provides researchers with valuable movement and habitat-use data while reducing invasiveness compared to traditional approaches. Having already been successfully deployed with free-ranging southern right whales, these tags offer important tools for studying and protecting their endangered northern counterparts.

The data collected from these tags can help inform efforts to reduce human-caused threats and better protect endangered whale populations in a rapidly changing ocean. The impact of this work extends beyond a single species. By improving how wildlife research is conducted, these collaborations help shape safer, more ethical approaches that can benefit other marine mammals and endangered species around the world.

At this year’s Calvin Schwabe Lectureship, pioneering leader Dr. William B. Karesh reflected on the power of communication and shared purpose in building healthier futures for people, animals, and ecosystems alike.

Read the recap from an inspiring conversation between Drs. Karesh and moderator Dr. Marcela Uhart (the 2025 Calvin Schwabe Lectureship speaker!) at the UC Davis Weill School of Veterinary Medicine:

A new study published in the journal npj Viruses found that climate change could drive rodent-borne arenaviruses into parts of South America that have never previously faced these diseases, with potential to expose millions more people to future spillover risk.

Researchers from UC Davis Weill School of Veterinary Medicine, including OHI's own Drs. Brian Bird and Marcy Uhart, collaborated to develop predictive models to better understand how these viruses may spread over the next 20-40 years.

This research highlights the importance of One Health approaches that recognize the deep connections between environmental change, wildlife, and human health.

Climate change is likely to drive rodent-borne arenaviruses into parts of South America that have never faced these diseases, putting new communities of people at risk, finds a study from the University of California, Davis. For the study, published in the journal npj Viruses, scientists incorporate...

Last Friday, we gathered for the 2026 UC Davis One Health Institute Annual Meeting.

It was a wonderful day filled with ideas, collaboration, and a shared commitment to improving the health of people, animals, and the environments we all depend on. The energy in the room reflected what makes work so powerful: people from different fields coming together to solve problems that no one discipline can tackle alone.

Thank you to everyone who joined us, shared their work, and helped make this year’s meeting such a meaningful gathering. We’re excited to keep building on this momentum together!

Have you listened to The Scientess Podcast yet? This new podcast from Dr. Karen Levy highlights the joy of science and the many paths women take to build meaningful careers in the field.

Episode 4 features Dr. Pat Conrad, whose career has shaped generations of scientists. After 33+ years, she retired as a distinguished professor of parasitology. In her career, she served as Associate Dean for Global Programs at UC Davis Weill School of Veterinary Medicine and Co-Director of UC Global Health Institute. Dr. Conrad has also been a longtime collaborator with the One Health Institute and a mentor to many, including our executive director, Dr. Woutrina Smith!

In this episode, she reflects on the path that led her to science, what has kept her inspired along the way, and why mentorship matters.

Tune in to hear her story and the impact one career in science can have across generations: www.scientess.org/ep-04-pat-conrad
