Upcoming Events

23 March, the official opening of Lighten Up! On Biology and Time

EPFL Pavilions, Lausanne ,Switzerland

Our new art-science exhibition on circadian rhythms, open from 24 March to 30 July 2023 and featuring works from:

Olafur Eliasson, Liliane Lijn, James Carpenter, Anne Noble, Susan Morris, Colin Fournier, Siegrun Appelt, Andreas Horlitz, Helga Schmid, Robin Meier, Anna Ridler, Alan Bogana, Rafael Gil Cordeiro, Marilyne Andersen, Ted Hunt, Kirell Benzi

This is the first time so many artworks based on biological rhythms and their evolution under the solar day-night cycle have been gathered together. Datasets have been transformed into tapestries, illuminated columns, synchronized oscillations, dreaming brains, 3D visualizations, and ceramic documentation of sleep. Architects and artists play with spaces that let in daylight following the arc of the sun across the sky, emphasizing its importance for the built environment and, ultimately, for our health and well-being. Many installations ask a fundamental question of how we think of, experience, and tell time. 

The exhibition was curated by Prof. em. Anna Wirz-Justice (Centre for Chronobiology, Psychiatric Hospital of the University of Basel and member of CET’s Board of Directors), Prof. Marilyne Andersen (Director of EPFL’s Laboratory of Integrated Performance in Design, LIPID), Prof. Sarah Kenderdine (Director and lead-curator of EPFL Pavilions, and director of EPFL’s Laboratory for Experimental Museology, eM+) and Dr. Giulia Bini (Curator and head of EPFL-CDH AiR Program “Enter the Hyper-Scientific”), and produced by EPFL Pavilions.

The annual Society for Light Treatment and Biological Rhythms (SLTBR) conference is from May 30th to June 1st in beautiful Lausanne, Switzerland! This conference brings together leading experts in the fields of circadian rhythms, sleep, and lighting to share their latest research and insights. The keynote speaker will be Debra Skene, who will give the latest insights on circadian rhythms in shift workers.

In addition to the keynote speeches and sessions, there will be a  platform for students to present their work and exchange ideas with fellow researchers. There will also be poster prizes, travel awards, and The J. Christian Gillin Young Investigator Award, given to foster and stimulate international exchange and new approaches in clinical aspects of biological rhythms, light therapy, or chronomedicine in general by young investigators.

The conference is an excellent opportunity for anyone interested in the fascinating field of biological rhythms and their impact on human health and well-being.

The Seminar Series “Current Topics in Sleep & Circadian Health” is organised by the Professorship Chronobiology & Health at Technical University of Munich (Munich, Germany) and the Max Planck Research Group Translational Sensory & Circadian Neuroscience at the Max Planck Institute for Biological Cybernetics (Tübingen, Germany) led by Prof. Dr. Manuel Spitschan, of CET’s Advisory Board. The 60-minute (45 min. talk + 15 min. Q&A/discussion) graduate-level seminars are free to join and take place via Zoom.

Hosts: Dr. Maydel Fernandez Alonso & Dr. Anna Biller

More than a million people have taken one or more of our three confidential automated online self-assessments. Your clients and patients can take the self-assessments on their own, and share their printed results with you to help you assess and monitor their depression, choose the best time of day to begin light therapy, if light therapy is indicated, and much more.

This collection of assessment instruments, designed and produced by the Clinical Chronobiology and Biometrics Research groups at Columbia University/New York State Psychiatric Institute, is available as a set at CET. See the tools we have found useful in working with affective disorders and sleep problems.

A respected group of clinicians and researchers write for on progress and directions in chronotherapeutics and allied sciences.

A curated collection of seminal papers and books gives an overview of major topics in the research, and application, of circadian science.

Our suggestions range from manuals offering step-by-step guidance for chronotherapy to reflections on the evolution of circadian rhythms within the cycle of day and night.

More than a million people have taken our three confidential Automated Online Self-Assessments. Take one (or all) of them and share the results with your doctor or therapist. Results can guide treatment decisions, such as choosing the best time of day for an individual to begin light therapy.

CET bloggers Michael Terman, Dan Oren, Ian McMahan and Abigail Strubel contribute their wisdom here.

Subscribe to our unique, free e-book series, an ever-growing collection with detailed practical guidance spanning infancy to old age, light versus darkness, melatonin administration, and much more.

Prominent researchers and clinicians write for CET about the latest news from their research and clinical practice – a unique, readable collection! Also included, CET articles with practical guidance for treatment.

Our suggestions range from a drug-free program to improve sleep, mood and energy to explanations of the circadian clock.
