As part of their advanced studies, third-year Cycle Ingénieur Polytechnicien students can opt for experimental mechanics courses. Nine sessions allow them to develop a scientific project at the cutting edge of theory and practice. Twenty projects are currently underway, several of which focus on environmental issues.
The Biomedical Engineering (BME) Seed Grant sponsorship programme, led by Abdul Barakat and supported by the Bettencourt Schueller Foundation and École Polytechnique and its Foundation, will come to an end in late 2025, after nearly seven years dedicated to innovation in biomedical engineering. On 20 November, during the 4th annual forum of the Engineering for Health (E4H) Interdisciplinary Centre, a dedicated session honoured the 11 winning projects, celebrated the advances they have enabled and highlighted the scientific and human impact of this structuring programme.
Some fluorescent molecules used to produce microscopic images of biological processes cause the cells into which they are introduced to stiffen. This phenomenon has just been demonstrated and quantified by a collaboration involving the Hydrodynamics Laboratory (LadHyX*). He is featured on the cover of the journal Cell Reports Physical Science.
For Science Day 2025, École Polytechnique paid tribute to women. Four female scientists from l’X recounted their career journeys and shared their passion with secondary school students. Take a look back at this inspiring event!
Every year, the Useful Fictions international summer school, initiated by the Arts & Sciences Chair and now run by the Useful Fictions Lab programme at the SPIRAL interdisciplinary centre, brings together artists, researchers and citizens around a common theme. The fifth edition, devoted to the atmosphere in all its dimensions, concluded on 5 and 6 September with an exhibition of the various projects at the Centre Wallonie–Bruxelles in Paris.
A publication by the Econophysics and Complex Systems Chair at École Polytechnique, supported by Capital Fund Management, reveals how a minority of altruistic individuals can transform the collective behaviour of a system. This work illustrates how physics tools can contribute to a better understanding of social and economic dynamics and shed light on collective issues ranging from the organisation of human societies to the design of new forms of artificial intelligence.
As part of a joint research project with Christophe Josserand, Deputy Director of the Hydrodynamics Laboratory (LadHyX) and lecturer at the École Polytechnique and the CNRS, École Polytechnique welcomed a visit from Sergio Rica, a researcher from the Pontificia Universidad Católica de Chile (PUC). This international mobility was supported by the Erasmus+ program was granted for its application to foster collaborations with partner universities in Chile.
By analyzing over 1,500 races, including those at the Paris 2024 Olympic Games, scientists from the Hydrodynamics Laboratory (LadHyX*) shed light on the importance of racing tactics in individual sprint performance. The study was published in The International Journal of Performance Analysis in Sport.
Two PhD students from École Polytechnique's laboratories took top prizes at the final of the Three Minutes Thesis (3MT) competition, following their...
Stilla Technologies develops and markets high-precision genetic analysis systems now used by several hundred laboratories worldwide. The American group Bio-rad laboratories is to acquire it for $225 million. This successful company has its origins on École polytechnique campus, and more specifically in the hydrodynamics laboratory (LadHyX*), in Charles Baroud's group. Charles Baroud looks back on the first steps of this adventure, which began in 2011.
École polytechnique students finished 3rd in the International Physicists' Tournament 2025 (IPT 2025). The aim of this tournament is to have teams debate physics problems they have researched beforehand.
Professor in the Department of Mechanics at École polytechnique, Caroline Cohen carries out her research at the Hydrodynamics Laboratory (LadHyX*), at the interface between science and sport. In particular, she helped athletes and federations prepare for the Paris Olympic and Paralympic Games.
