It's not too late to sign up for tonight’s Kraw Lecture event, taking place in person and virtually, where @ucsc researchers will break down the details about El Niño and what it could mean for California this winter. Follow the link in our bio to register! And if you can't make it, you can find the recording on the UCSC Arts and Lectures YouTube channel following the event.

🌧️El Niño is a recurring weather pattern that shapes climate in California and globally. It impacts seasonal rainfall, temperatures, and severe weather events. 

Because this event coincides with record global temperatures, experts predict this could be the most powerful El Niño on record—bringing heavier rainfall, higher sea levels, and massive ocean swells.

🌊While surfers are gearing up for big waves, the primary focus remains on protecting coastal communities and infrastructure at risk.

"This is about as sure as a thing you can get, in terms of predictive capabilities of @NOAA and world experts," notes Patrick Barnard, Research Director at UCSC's Center for Coastal Climate Resilience.

🔔 Look for future posts from UCSC Science to learn more about what we can expect from El Niño and what UCSC researchers are doing about it.

Fall quarter is officially in full swing🍂  Programs like Global and Community Health (GCH) give you in-class and career experience you need to pursue a career in public health or professional school to become a doctor, dentist, or pursue other medical pathways.

On Sept. 22, @ucsc.gch hosted a major orientation to give students an overview of the program, degree requirements, what to expect from both the GCH B.A. and GCH B.S. degrees, and to meet program staff and faculty. If you missed it, you can always connect with an advisor by scheduling an appointment on their website: gch.ucsc.edu. global and community health faculty and staff holding orientation sign by @ucscscience

🎗️Childhood Cancer Awareness Month, and we're marking it with a milestone for our clinical lab:

The Colligan Clinical Diagnostic Laboratory, the clinical arm of the UC Santa Cruz Genomics Institute's Treehouse Childhood Cancer Initiative, has earned accreditation from the College of American Pathologists (CAP)! 

Why it matters: 

Most genomic tests look for mutations in a tumor's DNA, but because pediatric cancers carry far fewer mutations than adult cancers, these tests often come up empty.

The Treehouse CARE analysis, developed by Professor Olena Vaske and her team, looks at RNA instead to see which genes a tumor has switched on or off. 

In the team's published study of relapsed, refractory, and rare cancers, their approach turned up findings of potential clinical significance in 94% of patients. Sometimes, these findings can point toward existing drugs or clinical trials that a mutation test would miss, meaning that the patient can start on a potentially life-saving treatment right away.

CAP accreditation is voluntary and sets a higher bar than the mandatory federal CLIA certification. The team hopes it will help open the door to insurance reimbursement and partnerships with new hospitals, broadening access to many more families.

Congratulations to the whole Colligan Lab team! 👏

It's time to bring complete genome sequencing to the clinic 🧬🩺 

Less than five years after first sequencing a human genome from end to end, we are working on making complete sequencing practical for personalized medicine. 

"Telomere-to-telomere" genome sequencing has already provided answers for patients with rare diseases whose genetic origins could not be determined by older sequencing methods. Access to more streamlined complete genome sequencing could have a huge and almost immediate impact for millions of patients with rare and undiagnosed diseases. 

This is a large collaborative project with researchers from all over the globe, led by @ucsc and @johnhopkinsu and funded by @nihgov

Where are they now?🌲💫 Class of 2025: One Year Later

Driven by a passion for scientific discovery, Owen Moosman (Stevenson '25, molecular, cell & developmental biology) channeled his fascination with genomics into a high-impact career in health research. Today, he is a research associate at @ucsf, where he interfaces with physicians, scientists, and students while studying autoimmune responses.

Attracted to UC Santa Cruz for its global reputation in genomics and RNA research, Owen analyzed pediatric cancer bioinformatics in the Treehouse Undergraduate Bioinformatics Immersion (TUBI) group and studied fish adaptation to extreme environments with the Kelley Lab.

Owen viewed his undergrad as a space to grow as both a researcher and a resource for others. Balancing his studies with his role as a Stevenson College peer advisor, he developed a mix of analytical precision and collaborative confidence. Today, Owen works as a research associate in the Biochemistry and Biophysics Department at the University of California, San Francisco. In the future, he plans to pursue a Ph.D. and continue in healthcare research. 

Life Beyond the Redwoods features ten Class of 2025 alumni who share how their time at UC Santa Cruz prepared them to launch their careers one year after graduation. Head to the link in @ucsc's bio to read more about Owen's story.

Meet Varad Desai, a first year microbiology student at UC Santa Cruz, who discovered an immersive field opportunity! 🦭🌊

Thanks to the Degree-Defining Experiences Program, Varad participated in the Año Nuevo Research Ambassador Program, where he introduced visitors to its unique coastal ecosystem. 

Through hands-on experience, he gained confidence in science communication, expanded his knowledge of marine mammals, and explored different niches within biology. The program helped him see how educating the public about wildlife can deepen people’s appreciation of the natural world. 

💡The Degree-Defining Experiences Program offers transformational learning opportunities for UC Santa Cruz undergraduates in the form of experiential field courses and other activities outside the classroom. Learn more or support the program! Visit the link in @ucsc’s bio or email amberwyld@ucsc.edu.

Where are they now?🌲💫 Class of 2025: One Year Later

Max Deneroff (Crown ‘25, human biology) leveraged his science foundation at UC Santa Cruz to pave his way to medical school. During his time on campus, he shadowed cardiac specialists during a clinical internship at Sutter Health, guided incoming students as a peer advisor, and co-founded the Campus Minds Advocacy Club to foster student mental health and well-being.

Growing up in San Diego surrounded by a supportive community, Max spent summers mentoring children on the autism spectrum. “It is the combination of all these factors, along with support from my family and guidance from my mentors, that shaped my aspirations to enter the field of medicine and what led me to UCSC.” These experiences further solidified the importance of empathy, patience, and creating inclusive spaces for others. 

Today, Max is a medical student at Kansas City University, College of Osteopathic Medicine, balancing hands-on clinical training and community health outreach.

Life Beyond the Redwoods features ten Class of 2025 alumni who share how their time at UC Santa Cruz prepared them to launch their careers one year after graduation. Head to the link in @ucsc’s bio to read more about Max’s story.

🚨 Imposter alert: The “American cheetah” wasn’t a cheetah at all! 🐆❄️

A new analysis of its DNA has found that although the extinct Miracinonyx trumani looked like a cheetah, it was actually a puma that ranged from Florida in the south all the way to the Yukon in the north.

The research team, led by @ucsc, found incredible genetic diversity in this species that impacted the ways it survived in different climates. While southern populations were more generalized hunters of wild game, their Arctic counterparts carved out a niche as fish specialists, likely feeding on salmon. 🐟

“These cats were remarkably flexible, much like pumas are across their range today,” said Molly Cassatt-Johnstone, a Ph.D. candidate in the Paleogenomics Lab at UC Santa Cruz and lead author of the study. “We found loss-of-function mutations in certain genes that regulate circadian rhythms, suggesting they may have adapted to the extreme light cycles of summers and winters in northern latitudes.”

The study also offers a sobering look at extinction. M. trumani did not experience a sudden collapse, but underwent a slow, long-term decline in genetic diversity and was unable to adapt when the climate shifted.

Research led by the UCSC Genomics Institute’s Paleogenomics Lab, with collaborators at @uafairbanks, the @yukongov , and @dmualumn
