Bike to Work is back at CERN, encouraging everyone to leave their car behind and enjoy the benefits of active travel. Choose a healthier and more environmentally friendly way to commute during May and June, or continue biking if you are already regularly in the saddle.

To take part, form a team of four colleagues - one of whom can participate as a pedestrian - and take on the challenge together. The goal is simple: commute by bike (or on foot) regularly, at least one day out of every two during the period of the campaign. It’s not about the number of kilometres you cover but about helping to build consistent, sustainable habits.

Whether you’re a seasoned cyclist or just getting started, every active commute contributes to your well-being, strengthens your connection with your colleagues and helps to reduce your impact on the environment.

Sign up on the Bike to Work website, where you can also apply to join an incomplete team. Ready to get moving?

A big thank you to all of you who sent in your photos for our photo competition on the theme ‘Spring at CERN’. We really enjoyed looking through them and it wasn’t easy to choose the winner. They are now available in a CC-BY photo collection, shown as a slideshow here:

Congratulations to Aneta Sabanovic from the IPT department, who wins the Chocopass kindly offered by the CAGI cultural kiosk at CERN and Geneva Tourism. The pass gives her the chance to explore Geneva for a day and taste chocolate from a range of chocolate shops.

We’d like to thank the International Geneva Welcome Centre (CAGI) and Geneva Tourism for offering a Chocopass to the winner! The CAGI cultural kiosk is located in CERN’s main building and is open from Monday to Friday from 8:30 a.m. to 1:30 p.m. It offers numerous discounts for local activities and events both in Switzerland and in France – Find out more about CAGI on their website.

Ethics is essential, in particular in our workplace. It contributes to a positive and productive work environment while also fostering trust among us, as CERN contributors, as well as the trust of our stakeholders, such as Member States, contractors and research institutions.

At CERN, our ethics-related framework is designed to guide us to act in accordance with the Organization’s values and with the conduct that is expected of us, and to establish and maintain a respectful working environment. It is up to each and every one of us to respect it.

To ensure that everyone is aware of the guidelines of our ethical framework, the HR Department has developed an e-learning course entitled “Ethics at CERN”, which is available in English and French on the CERN Learning Hub. As of now, this course is mandatory for all members of the CERN personnel.

To make our ethics-related framework more easily accessible, all the relevant information and resources can be found here: https://hr.web.cern.ch/ethics. If you have any ethics-related questions, please contact info-codeofconduct@cern.ch.

To go further, take the new e-course “Managing Conflict of Interest”

This online course introduces CERN’s policy on conflicts of interest and explains why identifying and managing such situations is essential for maintaining trust, integrity and fairness in the workplace.

The course addresses the following topics:

• What a conflict of interest is and why it matters
• The difference between actual and perceived conflicts of interest
• Examples of common conflict situations
• CERN’s policy on and official definition of conflicts of interest, including the rules on gifts, favours and hospitality
• Your responsibilities
• Where to find further guidance and support

The module also includes case studies to help you to recognise and respond to conflicts of interest in practice. Register now on the CERN Learning Hub.

On Saturday, 25 April 2026, marking the International Girls in ICT Day, the CERN Science Gateway will be opening its doors to girls aged 12 to 16 for a morning and afternoon dedicated to exploring the digital world.

This global event encourages girls to explore the many opportunities offered by information and communication technologies. 

Discover how artificial intelligence systems like ChatGPT work!  Or how a computer recognises images, sounds and even music. With scientists from CERN, you’ll learn how to train your own AI system and understand its strengths…and its limitations.

What if you created your own smart wristband?  In this workshop, you’ll train a model capable of recognising your movements (walking, jumping, clapping). It’s an amusing way to understand how AI can apply to real life!

Sign up and find out more, and check out the many activities being organised at the CERN Science Gateway throughout the day.

Don’t miss the next lunch & learn conference organised by the CERN Medical Service on the theme of “A healthy mind for a calmer future”. This latest session will be held in the Dirac Room (40/S2-D01) from 11.30 a.m. to 1.30 p.m. on 22 April and will focus on the topic of “Mind-Body connection: science, experience and resilience”. It will feature a talk by Dr Benzakhour from the Geneva University Hospitals (HUG) and a personal account by our colleague Julien Fernandez from the EN Department, who will share his journey on “Learning to live differently’.

Spaces are limited, so register now!

The event will also be webcast and recorded.
