As winter approaches, shorter days and bad weather mean reduced visibility for everyone on the road. Whether you're cycling, walking or driving, it’s crucial to remember the principle of "see and be seen". It isn’t just about looking out for yourself; it’s about respecting and being mindful of all road users, ensuring that everyone reaches their destination safely.

For those behind the wheel, winter visibility and road conditions demand extra caution. Be aware of your surroundings, particularly at junctions: look out for cyclists before pulling out. Beware of distractions, watch out for other vulnerable road users and reduce your speed to give you more time to respond to any unexpected situations on dark, wet or icy roads.

Winter often means navigating darker mornings and evenings, so making ourselves visible is key. Cyclists, make sure that your lights are bright and working properly —both front and rear lights are essential. Wearing reflective clothing or accessories makes all the difference. For pedestrians, reflective armbands or even light-coloured clothing help drivers to see you sooner, giving them more time to react.

We all use the same roads. Let’s make this winter a safe season for the entire CERN community. It’s all about respect.

For more information and safety tips, visit the Road Safety page.

At the beginning of the year, in order to make our ethics-related framework more easily accessible, the HR department grouped all the relevant information and resources under a single point of reference at https://hr.web.cern.ch/ethics.

To go further and ensure that every CERN staff member is aware of the guidelines of our ethical framework, the HR department has developed an e-learning course titled “Ethics at CERN”, now available in English and French on the CERN Learning Hub.

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

We encourage all CERN staff to take this new e-learning course. At CERN, our ethics-related framework aims to guide us to act in accordance with the Organization’s values and the conduct 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.

For more information or questions about ethics at CERN, please contact info-codeofconduct@cern.ch.

CERN is committed to providing optimal mobility solutions for its entire community, facilitating access to and movement around the sites. The SCE department is responsible for providing and maintaining the infrastructure and services needed to enable people to move around the CERN sites easily. A dedicated working group comprising representatives from all sectors of the Organization meets regularly to support SCE in its continuous efforts to improve mobility at CERN, ensuring variety and flexibility of soft mobility options and providing optimal connectivity for all road users, whatever their mode of transport. In the wider sustainability context, all our actions ultimately contribute to minimising the greenhouse gas (GHG) emissions arising from mobility at CERN.

Your responses to this short, seven-question survey will support continuous improvements to our mobility infrastructure and also help to calculate CERN’s Scope-3 GHG emissions arising from mobility for the next Environment Report.

The survey will be open until Friday, 6 December and we thank you in advance for your time and contributions.

Every response matters – take the survey* today! https://cern.ch/mobility-survey

Find out more about CERN’s extensive mobility solutions on this webpage: https://sce-dep.web.cern.ch/mobility-plan, which also includes the results of the previous mobility survey (2023).

Past information about GHG emissions at CERN can be found in the Emissions chapter of the third Environment Report (2021–2022).

* The survey is anonymous and has been developed in Microsoft Forms. A CERN login is required. The associated privacy notice can be consulted here.

Two blood donation campaigns have been run so far this year, in March and July, enabling the collection of some 200 donations in total, with 50-60 new donors coming to donate each time. This is a great result, earning CERN the 2nd place as the region’s biggest blood donor after the Hôpitaux universitaires de Genève (HUG). Thank you to all donors!

Whether we are regular or new donors, our contributions are crucial to ensure sufficient blood availability for those in need in the area. The Geneva blood barometer shows that blood stocks remain extremely low, notably for blood groups AB-, O-, A- and B-. Therefore, the CERN Medical Service will join forces once again with the HUG for a third blood donation session on Tuesday 26 November, from 8.30 a.m. to 4.30 p.m., in Building 29.

Can we still improve on past donations and collect more?

As a thank you, the HUG will be giving each donor a 10 CHF voucher, to be used in Novae’s Restaurants 1 and 2 at CERN.

Before coming to the Building 29 donation point, please make sure that:

• You are in good health and have no symptoms such as fever, cough, a cold or breathing difficulties;
• You are eligible to give blood:
  • Complete the brief online pre-donation questionnaire (in French)
  • Please consult this information sheet and this questionnaire issued by the HUG.
  • Note that only the pre-donation conversation with the nurse or doctor on the day can confirm your eligibility).
  • If returning from travel abroad or arriving from another country, perform the travelcheck on the HUG website (in French)
  • If you have recently been vaccinated against the flu or COVID, ensure 48 hours have passed since receiving the vaccination.
  • Please bring proof of ID with you on the day of the donation.

Save yourself time: pre-book your appointment with OneDoc

The possibility of pre-booking your appointment via the OneDoc platform is made available on this link. Spontaneous donors will be able to come at their convenience without an appointment, mindful that there may be some waiting time on the day.

We hope to see many of you at the donation point!

Give blood, save lives.

This November will see the launch of a new training programme, “Safety Matters for Supervisors”. This comprehensive training course aims to enhance the integration of Safety management practices into the Organization’s general management practices and thus foster a robust Safety culture at CERN. This initiative is designed to ensure that supervisors at all levels are fully aware of their Safety roles and responsibilities and are equipped with the necessary tools and support.

The programme will cover all facets of Safety at CERN, including occupational health and safety, with a focus on well-being and psycho-social risks, environmental protection and safe operational practices. Participants will receive a comprehensive Safety awareness toolbox, designed to help them develop a strong Safety network and effective management practices, positioning them as active contributors to a sound Safety culture.

Following the success of pilot sessions held in May and June 2024, the regular sessions will commence in November, starting with four sessions per year with the possibility of adding more, if needed. The training will be delivered through a blended format, beginning with three e-learning modules covering key Safety concepts, followed by two interactive workshops that will focus on practical applications and peer-to-peer learning.

The programme is highly recommended for new supervisors in their first year of appointment. Existing supervisors across all levels in both technical and non-technical fields are also encouraged to enrol when places are available. The programme has been aligned with the HR Learning & Development Leadership learning portfolio and approved by the CERN Learning Board, reinforcing the Organization’s commitment to embedding Safety into its core management practices.

Benoît Delille, Head of the HSE unit, sums it up: “This is an excellent opportunity for supervisors to enhance their leadership capabilities and contribute to a safer work environment. We encourage all eligible supervisors to participate in this programme and to take an active role in promoting a strong Safety culture at CERN.”

For more information and to sign up, follow this link.

Take part and help to make CERN a safer place for everyone!

CERN is committed to minimising its environmental impact through a wide range of projects aimed notably at managing energy use, cutting greenhouse gas emissions, conserving water, protecting biodiversity and managing waste. This Town Hall event will provide an overview of the key initiatives under way and highlight the progress made towards meeting CERN's current environmental targets at the end of Run 3, with an update regarding CERN’s third Environment Report (2021–2022), published in December 2023. You'll also hear about the updated goals for Horizon 2030 and the specific projects designed to achieve them.

This Town Hall event is not just an update – it’s an invitation for you to engage in shaping CERN’s environmental priorities. We’ll discuss how each of us can contribute to making CERN’s operations more sustainable and to meeting the Organization's commitment to environmental responsibility.

We encourage everyone to attend and be part of this important exchange. Your participation is key to our collective success in fostering a sustainable future at CERN. Don’t miss this opportunity to be involved!

When? 9 a.m. to 10.40 a.m., with coffee served at the end
Where? Main Auditorium (500/1-001).
The event will be webcast and a recording will be made available after the event.

The influenza season is approaching and with it comes the consideration of getting a flu vaccination to protect yourself and others.  The CERN infirmary will vaccinate any person working on the CERN site (MPE, MPA, temporary workers and contractors) provided the person brings their own vaccine and that the relevant medical questionnaire at the infirmary confirms there are no contraindications to vaccination. Both conditions have to be met for the vaccination to be administered. A medical prescription will be given to the patient after the vaccination to allow the reimbursement of the vaccine by the person’s health insurance provider.

CERN retirees and family members can obtain the flu vaccination in France or Switzerland from their general practitioner or chemist’s: the vaccination is also be reimbursed by the CHIS according to its own rules.

The infirmary is open for vaccination Monday to Friday from 8 a.m. to 12.30 p.m. and from 2 p.m. to 4.30 p.m.

For more information, see: https://hse.cern/fluvaccination.

Central heating will be progressively turned on throughout CERN from Monday 7 October 2024. All buildings will be heated within the next few days.

Delaying turning on the heating on campus was one of the measures of the Energy Savings campaign launched in 2022 and included in the measures foreseen by the ISO 50001 certification. According to these measures, the heating switch-on is no longer defined on the basis of a regular calendar but on the weather forecast, and more specifically on the average overnight temperature. Each day saved through postponing the heating start represents significant energy savings for the Organization.

We therefore thank everyone for their understanding and supportive efforts.

The aim of the FCC Feasibility Study, which is scheduled to be completed in 2025, is to determine the technical and financial viability of the FCC at CERN, with a particular focus on its geological aspects, the environmental impact, the infrastructure design, the civil engineering and the detectors and the R&D for the technologies needed to ensure the efficiency and durability of the proposed colliders.

With this in mind, in 2023 CERN conducted initial assessments on the ground in order to refine the existing geological and seismic data, as well as data regarding flora and fauna for the purpose of conservation. This first phase involved a visual inspection of the areas of land concerned.

In the second phase of the Study, which has just started, the focus is on the stability of the subsoil. This is a crucial step, as the project includes plans to bury the collider approximately 200 metres underground. Before going any further with the analyses, it is vital to check the nature of the soils along the entirety of the planned route to see if they are suitable for this kind of infrastructure and to determine at exactly what depth it could be installed.

The results of these analyses will make it possible to refine the placement scenarios and determine which ones should be prioritised if the project is approved, taking into account both the environmental objectives for the areas on the surface and the underground constraints.

Based on the results of the Study, CERN’s Member States will make a decision about the project as a whole and, in particular, about the prospects for commissioning the FCC in the 2040s.

For further information about the investigations under way in the canton of Geneva (Switzerland) and in the departments of Ain and Haute-Savoie (France), and about the related potential noise pollution (linked, in particular, to the use of lorry-mounted seismic vibrators), visit the “CERN and its neighbours” website and the FCC Feasibility Study website.

When it comes to medical emergencies, few conditions strike as suddenly and as devastatingly as a stroke. Strokes occur when the blood supply to your brain is interrupted and they are life-threatening emergencies. If not treated quickly, there may be significant after-effects. The best known is hemiplegia (paralysis of one side of the body), but there are many others, such as speech disorders, sensory disorders, emotional disturbances and more. According to the World Stroke Organization, there are 12.2 million new strokes globally each year. What’s more, strokes concern us all, with one in four people over the age of 25 predicted to suffer a stroke during their lifetime.

World Stroke Day is observed every year in October to raise awareness of the serious nature and high rates of strokes and of how to prevent and treat them, and to ensure better care and support for survivors.

CERN’s Medical Service has teamed up with several local partners for an event on Thursday, 17 October, featuring interactive information stands, in order to help us all to better understand and prevent strokes.

The Hôpitaux Universitaires de Genève (HUG) will be present to explain the warning signs of a stroke – using virtual reality goggles to create a tangible experience – and how strokes are managed in the emergency room.

The Medical Service team will offer you tips and tricks on mental health awareness and how to reduce stress, a key factor in the occurrence of strokes, such as how to use the cardiac coherence technique.

Medical staff will be on hand to measure your blood pressure, an important health indicator in stroke prevention.

Novae will host a stand to explain the impact of nutrition on our health and offer tips to better prevent strokes, while FRAGILE and the World Stroke Organization will cover specific information on the support and resources available through their networks.

Finally, the CERN Knowledge Transfer group will demonstrate two ongoing projects linked to strokes, namely the CAFEIN platform and the TRUSTroke project.

The campaign programme includes a fascinating lunchtime conference, with speakers from HUG discussing recent advances in stroke medicine. It will also feature testimonials from two young stroke survivors, Elise Mathy and Louis Gustin, who will share their personal experience in a talk entitled “Journey into aphasia”.

Visit the stands in Restaurant No. 1 and the foyer of Building 60 from 10 a.m. to 3 p.m. and don’t miss the conference taking place from 12 noon to 1.30 p.m. in the filtration plant, Building 222. Sign up to attend the conference at this link.

On Friday, 27 September 2024, the Swiss Parliament adopted amendments to the Loi sur l’encouragement de la recherche et de l’innovation (Federal Act on the Promotion of Research and Innovation (LERI)). In accordance with the wishes of the Swiss Federal Council, a legal basis now exists for the development of a Plan sectoriel fédéral (Federal Sectoral Plan) regarding CERN’s buildings and installations.

Under this plan, which is currently being developed, the Federal Council intends to clarify the administrative procedures concerning land-use planning and improve the scheduling certainty of strategically important CERN projects that entail territorial development.

CERN participated in the consultation opened in March 2023 with a view to amending the LERI and subsequently appeared before the Science, Education and Culture Committee of the National Council (Lower Chamber of Parliament) in May 2024.

The adoption of the amended LERI by the Swiss Parliament is an important milestone. CERN appreciates the committment of the Swiss authorities, in their role as Host State, to science, as is reflected in the Federal Council’s Foreign Policy Strategy 2024–2027.

CERN will continue to cooperate closely with the authorities in the pursuit of their work with the aim of improving support for the Organization’s future projects, including the Future Circular Collider (FCC), in the event of its realisation, in accordance with the Federal Council’s decision of 10 December 2021.
