Data for a better vanadium flow
Scientists at PSI have developed a dynamic database on the global vanadium economy. This is meant to advance the use of special energy storage systems – and thus the energy transition.
Big heart, acute senses key to explosive radiation of early fishes
X-rays of a 400-million-year-old fossil illuminate a key moment in our deep evolutionary past.
POLIZERO: PSI project shows paths to climate neutrality
The net-zero target is achievable – if Switzerland sets the right political course now.
Merlin-7: New model for high-performance computing
An innovative computing cluster is ushering in a new era of computer-aided research at PSI.
