The European Biological Rhythms Society (EBRS) is a scientific organization dedicated to the study of biological rhythms, including circadian, seasonal, and other time-based physiological processes in living organisms. Founded in 2005, the society serves as a hub for chronobiologists, or scientists who study biological rhythms and their effects on living organisms, across Europe and more broadly across the world. It hosts international congresses biennially to present advancements in chronobiology and continues a tradition of organized biological rhythms research in Europe that dates back to the 1970s, with roots in the earlier European Pineal Study Group. EBRS is also known for awarding prominent lectureships and honors to recognize outstanding contributions to the field. It is a unique society that has developed overtime as the field of biological rhythms has evolved. EBRS functions to connect scientists and enthusiasts within the field, as well as other societies, contributing to the future of chronobiological sciences.

== History ==

=== Founding === The EBRS was established in Frankfurt am Main, Germany, on September 4, 2005. EBRS traces its origins to earlier organizations, including the European Pineal Study Group (founded in Amsterdam in 1976), the European Pineal Society (1990), and the European Pineal and Biological Rhythms Society (2000). The EPSG, or original reiteration of this group, derived from a group of people interested in studying the pineal gland and the brain while encouraging varied approaches to science. An early letter regarding the formation of the EPSG written by Professor Paul Pévet claims that "[t]his association would be open to all scientists actively working in the field of pineology [i.e., the study of the pineal gland] ... as well as to all scientists interested in this field". The evolution of this society reflects changes in the research regarding biological rhythms at the time. In the early days of the society, study of the pineal gland was a major focus within the field of chronobiology and a focus of the members of the group. In 2000, the European Pineal Study Group became the European Pineal and Biological Rhythms Society, reflecting a change of the scope of the society to become broader. The final foundation of the EBRS as it is known today has facilitated collaborations with other similar groups around the globe.

=== Research Traditions === The development of the EBRS is best understood through the evolution of chronobiology research in Europe. Historically, two principal currents have defined research in this domain. One school, represented by figures such as Franz Halberg and Alain Reinberg, emphasized the systematic study of biological rhythms to optimize medical outcomes. This approach emerged during the mid-20th century as a specialized branch of physiology that sought to refine the temporal organization of physiological functions for improved disease prevention, targeted intervention, and personalized pharmacological timing. It later led to the conceptual foundation of chronotherapy and the broader medical discipline of chronobiology. A second tradition, associated with scientists like Colin Pittendrigh and Jürgen Aschoff, focused on understanding the fundamental nature of biological clocks. This mechanistic approach prioritized the discussion of rhythm generation, anatomical substrates, and the molecular and genetic basis of circadian timing systems. As the EBRS originates in a study group initially focused on the pineal gland and neuroendocrine regulation, the society was "by birth" aligned with the mechanistic approach. However, from its earliest phases, it embraced a broad intellectual inclusivity, welcoming both European and non-European researchers from medical fields including, but not limited to, clinical, anatomical, and pharmaceutical.

=== Terminology Shifts === The EBRS also distinguished itself from its precursors by adopting the terminology of "Biological Rhythms" over "Chronobiology". The latter was originally used in the context of clinical timing, disease prevention, and pharmacological optimization. While this focus was valuable, it did not fully capture the growing diversity of approaches being developed within the field, particularly those rooted in systems of neuroscience and molecular biology. In contrast, the term biological rhythms was viewed by the early members of the EBRS as conceptually more expansive. It accommodated a broader range of research objectives—from understanding intracellular feedback loops and neuronal network oscillations to investigating organisms' behavioral patterns.

=== Inclusivity === Till this day, the EBRS continues to organize international congresses, promote early-career researchers, and collaborate with other scientific bodies such as the Society for Research on Biological Rhythms (SRBR) and the Japanese Society for Chronobiology to shape the future of chronobiological science.

== Meetings == Since 1978, the EBRS has been hosting regular congress meetings in partnership with universities, sponsors, and affiliated scientific organizations across Europe every 2 to 3 years on frontier research in chronobiology. Notable among these partners are the Japanese Society for Chronobiology and the European Sleep Research Society (ESRS). The congress typically takes place in the summer and runs for five days. It's open to researchers from around the world, with abstract submissions accepted up to four months in advance. Acceptance decisions are usually sent out two months before the event, allowing attendees to plan accordingly. Registration fees range from €160 to €700, depending on factors like early registration and participant category. More than just a scientific conference, the EBRS meetings are a space for interdisciplinary exchange and collaboration for breakthrough. Researchers present new findings, debate evolving ideas, and discuss future directions for the field. From lectures to poster sessions, the event encourages participants to connect across generations, disciplines, and continents.

=== CARE === In awareness to carbon dioxide emission footprint, CAbon REduced conferencing (CARE) was pioneered in 2019, dedicated to the contribution of experimental values and collaboration opportunities. CARE is known for its prompt organization of virtual meetings. Of the two it has fostered, the one on July 9, 2020 hosted a workshop that explored the interaction of chronobiology with SARS-CoV-2 sciences, reviewing the circadian clock's regulation in the viral infection process and informing potential therapeutic strategies against SARS-CoV-2 and COVID-19 epidemics.
