Next blood donation campaign on 28 November

Mon, 20/11/2023 - 12:28
Next blood donation campaign on 28 November

At the last blood donation campaign on 17 July 2023, 120 donors came along to give blood, of which 34 were first-timers. 76 donations were collected. Before the collection, the HUG presented a shortage of group A+ blood. Thanks to this collection, we were able to increase the blood reserves of group A+. This is a great success and we thank you for your contribution!

Nevertheless, the Geneva blood barometer, which is regularly updated, shows that blood stocks continue to run extremely low. CERN will hold a third blood donation session on Tuesday 28 November, from 8.30 a.m. to 4.30 p.m. in collaboration with the Hôpitaux universitaires de Genève (HUG), in Building 29.

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 complete this questionnaire issued by the HUG (but 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.

*New*: possibility to make an appointment in advance

Based on the experience of the donation campaign in July, 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.

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.

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

Give blood, save lives.

CERN Colloquium | 30 November | The Einstein Telescope: the next-generation gravitational-wave observatory in Europe

The Einstein Telescope: the next-generation gravitational-wave observatory in Europe, by Dr Michele Punturo (INFN, Perugia).

Thursday, 30 November 2023, 4.30 p.m.–5.30 p.m.
Room 222/R-001
Live webcast available at:

Gravitational waves (GWs) are the newest tool for exploring the Universe. Advanced Virgo and Advanced LIGO have opened a new window into the Universe by detecting GW signals in the Hz–kHz frequency range. Pulsar timing array experiments have just announced the detection of GWs in the nanohertz frequency range.

A new generation of GW interferometric observatories is being prepared to replace the current generation of GW detectors within the next decade. This will make it possible to search almost the entire Universe for GW signals. The Einstein Telescope (ET) is at the forefront of the design, preparation and implementation of a next-generation gravitational-wave observatory in Europe. An overview of the observatory’s scientific objectives, design, required technologies and project organisation will be presented at the event.

Watch: safety concerns us all

Watch: safety concerns us all

CERN strives for excellence in matters of safety, which covers occupational health and safety, the safe operation of CERN’s installations and the protection of the environment. Prevention is at the heart of this endeavour.

To raise awareness and support the effort to make CERN a safer place for everyone, the HSE unit publishes safety flyers and posters, such as the newcomer safety awareness flyer, recalling the basic prevention principles and the people and services that provide support in matters of safety. The video below is the latest of these communications and aims to remind everyone of the variety of hazards present on the CERN site and the prevention measures to adopt.

General safety communications by the HSE unit are complemented by more specific information provided by the departments and the LHC experiments, tailored to their activities, the specific risks these entail and their organisation.

Safety starts with all of us. During our workday we encounter a variety of hazards, from the general to the more specific. Common risks, such as trips and falls or incidents involving our movements around the site, concern us all, while more specific hazards depend on the workplace and/or the nature of our activities. It is thus important to stop and think before beginning an activity and then act, taking account of the risks involved and the corresponding mitigation measures.

Watch this video to see what you can do to improve safety at CERN. (Video: CERN)
