C’est l’hiver, soyons vigilants : comment prévenir les chutes et autres accidents de saison

Wed, 18/01/2023 - 17:14
Preventing falls and other accidents now that winter is upon us

With the snow and the ice, pavements and road surfaces can resemble skating rinks, increasing the risk of slips and injuries. Winter sports are also a common source of accidents. At this time of year, the CERN infirmary sees more people coming in with musculoskeletal problems after a fall.

In 2021 in Switzerland, 195 000 people were injured after tripping, falling or slipping while walking or on the stairs (Suva, 2021). At CERN, in 2022, three people fell off their bicycles, resulting in one being signed off work for eight days, and one person fell while walking and was signed off for four days.

In addition, over 30 000 employees in Switzerland suffer winter sports injuries every year (Suva, 2021). According to a report published in 2021 by the French Observatoire d'accidentologie des sports d'hiver, more than 110 000 people experienced traumatic injuries in France in 2020.

In downhill skiing, sprained knees are the most common injury, accounting for almost a third of the total (32%), with shoulder injuries – mainly dislocated shoulders – accounting for 15%. Snowboarding most commonly results in wrist fractures (25%) or shoulder injuries (19%).


So how can you glide through the season smoothly and make the most of the winter sports opportunities?

Whether or not you’re a fan of snow sports, take care during your journeys and activities.

Whichever sport you choose, make sure that you’re prepared and have the right kit. Here are some basic tips for skiers and snowboarders in particular:

  • Good physical preparation is key to reducing the risk of an accident. Strengthen your muscles and do cardiovascular workouts (see advice (in French) from the Swiss national accident insurance fund Suva on making the most of the season).
  • Get your ski equipment checked every year; a lot of sprained knees are caused by badly adjusted fastenings or boots.
  • Wearing a helmet reduces the risk of head injury by 35% in the event of an accident: get a helmet that meets the standards and is the right size for your head.
  • Warm up / stretch before hitting the slopes.
  • Wear wrist guards if you’re a snowboarder.
  • Eat regularly and drink hot drinks to stay hydrated.
  • Slow down.

Have a great winter!

Courier Webinar: "The axion search programme at DESY" - 26 January

Join the audience for a live webinar at 3 p.m. on 26 January 2023 exploring the ongoing axion search activities at DESY. 

The worldwide interest in axions and other weakly interacting slim particles (WISPs) as constituents of a dark sector of nature has strongly increased over the last years. A vibrant community is developing, constructing and operating corresponding experiments, so that most promising parameter regions will be probed within the next 15 years.

Many of these approaches rely on WISPs converting to photons. At DESY in Hamburg, larger-scale projects are pursued: the “light-shining-through-a-wall” experiment, ALPS II in the HERA tunnel, will start data taking soon. The solar helioscope BabyIAXO is nearly ready to start construction, while the dark matter haloscope MADMAX is in the prototyping phase.

This webinar will introduce the physics cases and focus on the axion search activities ongoing at DESY.

How can particle accelerators address environmental issues? A 10-day challenge for multidisciplinary teams of young people!

Tue, 13/12/2022 - 11:40
How can particle accelerators address environmental issues? A 10-day challenge for multidisciplinary teams of young people!

We invite students to take part in an EU-funded challenge to imagine new multidisciplinary solutions to address environmental issues by using particle accelerators. This challenge will be tackled by multidisciplinary teams invited to stay, all expenses covered (*), for 10 days at the European Scientific Institute (ESI) on the France-Geneva border.

Some particle accelerators such as the Large Hadron Collider (LHC) at CERN are the largest scientific tools on Earth. But beyond driving large scientific discoveries, many smaller accelerators are used in medicine to cure cancer and they also have many other applications in our daily lives.

For 10 days, students with different academic backgrounds will join teams of six to imagine innovative solutions on how can particle accelerators be used to tackle environmental challenges. On the 10th day, they will present their work to a jury of experts at CERN.

To help in this task, students will be offered high-level seminars on particle accelerators, on environmental challenges and on innovation as well as a stimulating environment to discuss these issues.

This initiative is put forward by the I.FAST project, funded by the European Union’s Horizon 2020 research and innovation programme. It stems from the historic collaboration between the ESI, CERN and others partners to run the Joint Universities Accelerator School.

Tomalla Prize ceremony at the University of Geneva | 16 December

Tue, 13/12/2022 - 11:26
Tomalla Prize ceremony at the University of Geneva | 16 December

The Tomalla prize is attributed every few years by the Tomalla Foundation for outstanding work in gravity research (see for previous prize winners and other activities of the Tomalla Foundation).

The Italian physicist Alessandra Buonanno has been awarded the Tomalla Prize 2022 for her outstanding work
on gravitational wave physics, especially for the effective one-body approach to describe the gravitational waves emitted by binary black holes or neutron stars, but also for other important contributions relevant for the detection of gravitational waves.

Alessandra Buonanno studied physics in Pisa where she finished her PhD in 1996. After a brief period spent at the theory division of CERN, she held postdoctoral positions at the Institut des Hautes Etudes Scientifiques (IHES) in France and at the California Institute of Technology in the USA. She was a permanent researcher at the Institut d'Astrophysique de Paris (IAP) and Laboratoire Astroparticule et Cosmologie (APC) in Paris with CNRS before joining the University of Maryland as physics professor.

Since 2014 she is a director at the Max Planck Institute for Gravitational Physics in Potsdam, and holds a professorship position at the University of Maryland. Since 2017 she is also honorary professor at Berlin’s Humboldt University and at Potsdam University. She is member and principal investigator of the LIGO Scientific Collaboration, which discovered the first gravitational wave from two coalescing black holes in 2015.

In her theoretical work, Prof. Buonanno made seminal contributions to the modelling of gravitational
waves from the coalescence of compact-binary systems, most importantly two orbiting black holes, by combining analytical and numerical-relativity methods. A precise modelling of this signal is crucial to distinguish gravitational waves from the many contributions to the ‘noise’ in the detectors. In particular, Prof. Buonanno and her group contributed importantly to the generation of gravitational wave ‘templates’ which observers use to compare their signals with and interpret their astrophysical origin.

The Tomalla Prize ceremony 2022 will take place on December 16 at 17:30
in the Grand Auditoire de l’Ecole de Physique (24, Quai Ernest Ansermet, Genève)

The laureate will give a colloquium about her work.

The ceremony is open to the public.

Space encounters: meet astronauts Paolo Nespoli and Slawosz Uznanski at CERN - 16 December

On the occasion of the Italian National Day of Space, ESA astronaut Paolo Nespoli shares his career highlights and the lessons learned from the perspective of his more than 300 days in orbit on the Space Shuttle and Soyuz missions and a long-duration flight to the International Space Station. With the participation of CERN engineer Slawosz Uznanski, who has just been recruited in the 2022 class of the European Astronaut Corps.

Join the audience in CERN's main auditorium on 16 December at 11 a.m.. Organisation and Moderation: Paola Catapano, IR-ECO-ECP, with the support of the Italian Embassy in Bern, of the Italian General Consulates in Geneva and Zurich, and with the collaboration of the CERN Library.



Paolo Nespoli 
Major Paolo Angelo Nespoli  is an Italian astronaut and engineer at the European Space Agency (ESA). In 2007, he first traveled into space aboard the Space Shuttle Discovery as a mission specialist of STS-120. In December 2010 he again traveled into space aboard the Soyuz TMA-20 spacecraft as an Expedition 26/27 flight engineer. Nespoli's third spaceflight was on board Soyuz MS-05, which launched in July 2017 for Expedition 52/53. He has spent more than 300 days on the International space Station. He was also ESA’s oldest active astronaut prior to his retirement in 2019.




Slawosz Uznanski
CERN staff member Slawosz Uznanski, reliability engineer of the LHC new power converters in the Accelerator Systems department (SY), was selected in November to be in the reserve pool of the new class of ESA astronauts. Slawosz, who has held a passion for space and exploration since his early childhood, has successfully passed all the stages of a year-long extremely competitive selection process, which started in summer 2021 with more than 22 500 applicants from ESA Member and Associate Member States. This was the first call for new ESA astronaut applicants since 2008.

Swiss ban on laser pointers: how to return them for appropriate disposal

Mon, 05/12/2022 - 10:41
Swiss ban on laser pointers: how to return them for appropriate disposal

The Bulletin of 31 October 2022 featured a reminder concerning the ban on laser pointers on Swiss soil in 2019, as per articles 22 and 23 of the Ordinance to the Swiss Federal Act on Protection against the Risks associated with Non-Ionising Radiation and with Sound (O-NIRSA). This concerns a ban on all laser pointers belonging to classes 1M, 2, 2M, 3R, 3B and 4.

The term “laser pointer” refers to a laser device that, on account of its size and weight, can be held in and guided by hand and that emits laser radiation for the purpose of pointing out objects and locations. These are most commonly used at CERN for giving presentations.

Swiss law is now more restrictive than French law, which authorises class 1, 1M, 2 and 2M laser pointers (décret n° 2012-1303 du 26 novembre 2012 – in French). The tightening of Swiss law follows various incidents in Switzerland involving the use of these lasers.

Following a recent incident in Switzerland involving people in possession of such devices, CERN has decided to ban their use on the whole site, including the French part. Class 1 pointers are still allowed for use in presentations. The ban will be included in the new rule on laser safety that is currently being drafted.

Laser pointers can be disposed of via the appropriate CERN waste pathways, as electronic waste, once the batteries powering them have been removed.

Should you be in possession of a laser pointer of class 1M or above, you can return it for appropriate handling and disposal by placing it in one of the dedicated blue containers for electronics provided by the SCE Storage, Recuperation and Sales service, or hand it in directly at Building 133. 

Thank you for your cooperation.
