Deborah S. Kelley awarded the Wallace S. Broecker Medal

For impactful contributions to marine geoscience, deep-sea vent research, and education, through connecting systems, people, and ideas

2026-01-13

(Press-News.org) Deborah S. Kelley, Professor in the School of Oceanography at the University of Washington, has been awarded the Wallace S. Broecker Medal by The Oceanography Society. This honor recognizes her innovative and impactful contributions to marine geoscience and chemical oceanography, her leadership in interdisciplinary and collaborative research, and her sustained commitment to education and mentorship.

Dr. Kelley will receive this honor at The Oceanography Society Honors Breakfast, February 24, 2026, during the Ocean Sciences Meeting in Glasgow, Scotland, and will also present a plenary lecture during the society awards session on February 25 at the same conference.

The Broecker Medal honors innovative and impactful contributions to the advancement or application of marine geoscience, chemical oceanography, or paleoceanography. This medal also seeks to recognize individuals who have made significant contributions toward educating and mentoring students and early-career ocean professionals or who have conducted significant interdisciplinary research and/or collaborative work toward meaningful societal impact.

Dr. Kelley is best known for co-leading the 2000 submersible expedition that discovered the Lost City Hydrothermal Field on the Mid-Atlantic Ridge—an entirely new type of hydrothermal system driven by serpentinization of mantle rocks rather than magmatic heat. Featuring massive carbonate chimneys, rising 60 m above the surrounding seafloor, venting highly alkaline fluids rich in hydrogen and methane, Lost City fundamentally altered scientific understanding of fluid–rock interactions, chemosynthetic ecosystems, and the links between geology, chemistry, biology, and the potential origins of life on Earth and beyond.

“Dr. Kelley made one of the most important contributions to marine science in decades with the discovery and documentation of the Lost City Hydrothermal Vent Field,” said Jeffrey A. Karson, Professor Emeritus of Earth & Environmental Sciences at Syracuse University. “Her comprehensive, collaborative work on this previously unknown type of system has inspired new ideas about life-sustaining environments and the emergence of life on Earth and beyond.”

Beyond discovery, Dr. Kelley has helped to transform how the ocean is observed. As director of the cabled component of the NSF’s Ocean Observatories Initiative Regional Cabled Array, she played a leadership role in the design, installation, and long-term operation of nearly 900 kilometers of high-power fiber-optic cables and more than 150 seafloor and water-column instruments. This real-time observatory, operational since 2014, delivers continuous data and high-definition video from active submarine volcanoes, hydrothermal systems, earthquake zones, and methane seeps, shifting ocean science from episodic expeditions to sustained, open-access monitoring with global scientific and societal value.

A defining element of Dr. Kelley’s legacy is her dedication to education and mentorship. Through programs such as VISIONS at Sea, she has taken more than 200 students to sea, integrated cutting-edge research into education, and mentored generations of early-career scientists. Her inclusive, interdisciplinary approach has helped shape leaders across marine geoscience, chemical oceanography, and related fields.

“Perhaps her greatest and longest-lasting contributions will be through her mentoring,” said Richard “Rick” Murray, Senior Scientist (emeritus) at Woods Hole Oceanographic Institution. “She is an international resource who changes people’s lives through those experiences.”

Through groundbreaking discovery, visionary infrastructure development, interdisciplinary collaboration, and deep investment in people, Dr. Kelley has advanced the core aims of the Wallace S. Broecker Medal—connecting Earth systems science with education, collaboration, and meaningful societal impact.

Novel immunotherapy demonstrates early potential to overcome resistance to immune checkpoint therapy

2026-01-13

According to a Phase I study led by researchers at The University of Texas MD Anderson Cancer Center, published today in Nature Medicine, the novel monoclonal antibody linavonkibart demonstrated the potential to overcome treatment resistance to anti-PD-1 immune checkpoint inhibitors in multiple cancer types. The trial was led by Timothy Yap, M.B.B.S., Ph.D., professor of Investigational Cancer Therapeutics and vice president and head of clinical development in MD Anderson’s Therapeutics Discovery division. “This ...

LLM treatment advice agrees with physician recommendations in early-stage HCC, but falls short in late stage

2026-01-13

Large language models (LLM) can generate treatment recommendations for straightforward cases of hepatocellular carcinoma (HCC) that align with clinical guidelines but fall short in more complex cases, according to a new study by Ji Won Han from The Catholic University of Korea and colleagues publishing January 13th in the open-access journal PLOS Medicine. Choosing the most appropriate treatment for patients with liver cancer is complicated. While international treatment guidelines provide recommendations, clinicians must tailor their treatment choice based on cancer stage and liver function as well as other factors such as comorbidities. To assess whether LLMs can provide treatment ...

Aboard the International Space Station, viruses and bacteria show atypical interplay

2026-01-13

In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth. Phil Huss of the University of Wisconsin-Madison, U.S.A., and colleagues present these findings January 13th in the open-access journal PLOS Biology. Interactions between phages—viruses that infect bacteria—and their hosts play an integral role in microbial ecosystems. Often described as being in an ...

Scientists create a system for tracking underwater blackouts

2026-01-13

(Santa Barbara, Calif.) — Clouds, smoke and fog may darken the skies, but sediment, algae blooms and organic matter can turn day into night on the seafloor. That’s why an international team of scientists have created the first framework to identify and compare these marine blackouts. The study, published in Communications Earth & Environment, introduces the concept of a marine darkwave: a short-term but intense episode of underwater darkness that can severely impact kelp forests, seagrass beds and other light-dependent ...

Fruit fly pigmentation guides discovery of genes that control brain dopamine and sleep

2026-01-13

Dopamine in the brain influences movement, learning, motivation and sleep. In humans, problems with dopamine are linked to conditions like Parkinson’s disease, depression and sleep disorders. While scientists know a great deal about how dopamine works in the brain, they know less about how the body controls dopamine levels. Understanding this could help treat diseases where dopamine is disrupted. In a new study published in iScience, researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Institute at Texas Children’s Hospital (Duncan NRI) worked with the laboratory fruit fly to find new genes involved in regulating dopamine ...

New mega-analysis reveals why memory declines with age

2026-01-13

A landmark international study that pooled brain scans and memory tests from thousands of adults has shed new light on how structural brain changes are tied to memory decline as people age. The findings — based on more than 10,000 MRI scans and over 13,000 memory assessments from 3,700 cognitively healthy adults across 13 studies — show that the connection between shrinking brain tissue and declining memory is nonlinear, stronger in older adults, and not solely driven by known Alzheimer’s-associated genes like ...
