Welcome to the digital edition of the January/February 2022 issue of CERN Courier.

The vast range of detector and accelerator technologies on offer, and the need for stronger and international collaboration to build increasingly large and sophisticated facilities, makes modern-day community planning exercises more complex and necessary than ever. Two technology R&D roadmaps released in December set out a path to achieve the goals of the 2020 update of the European strategy for particle physics, focusing on the next generation of facilities after the LHC (p7), while a similar exercise, Snowmass 2021, recently got under way in the US (p43).

As for what physics might lie ahead, exploring the flavour anomalies is an exciting prospect at the proposed Future Circular Collider (p35), while probing the twin mysteries of the cosmic acceleration and the smallness of the electroweak scale is another priority for future experiments (p45).

Also in this first issue of the new year: Borexino neutrinos reveal the secrets of stellar fusion (p24); CERN’s beam-transfer lines undergo a revolution in energy efficiency (p39); tackling the neutron-lifetime puzzle from space (p11); low-cost linacs for radiotherapy (p30); top tips on pivoting your career (p49); the latest meeting reports (p19); LHC-experiment results (p15); reviews (p47); miscellanea (p58) and much more.
