Combating cancer growth
Researchers at PSI and the University of Zurich have determined the mechanism behind an important signalling protein that spins out of control in certain types of cancer. This paves the way for new approaches to cancer treatment.
A world-first lens brings neutrons into sharper focus
From thick samples to processes inside bulky equipment, a new type of lens opens the door to high-resolution neutron imaging of working systems.
The role of dimensionality, symmetry, and correlation in quantum time scales
Time, though ubiquitous in our daily experience, is a physical quantity not very well understood. It lies at the crux of efforts to unify the physical paradigms, being regarded as a constant background in some paradigms such as Newtonian mechanics or quantum mechanics, while completely internal to the objects in other paradigms such as general relativity. In quantum mechanics, specifically, the inability to find an operator for time as for spatial positions indicates the impossibility to find an observable which represents the external time coordinate. Nevertheless, an operator can often be found to represent the internal time duration of some certain process. The Eisenbud-Wigner-Smith (EWS) time scale is a famous example of such a time duration operator, which describes the single-particle scattering or ionization time scale.
Nano-insights into bone stability
PSI researchers have used a new imaging technique to more precisely assess the nanostructure of bone in the neck of the femur. This could help understand why they fracture relatively often.
Virtual tissue staining in 3-D
Researchers at the Paul Scherrer Institute PSI have developed an AI platform that stains grey micro-CT data like the results of classical histology. This could in the future enable analysis of tissues in three dimensions instead of just thin microscopic sections.
Spatial Evolution of Coke in ZSM-5 Catalysts During Methanol-to-Hydrocarbons Conversion Revealed by In Situ X-Ray Photoelectron Spectroscopy
Coking is the central source of deactivation of zeolite catalysts. Using in situ XPS along with complementary methods, we identify differences in the formation kinetics and composition of surface coke on industrially relevant ZSM-5 catalysts during MTH conversion, demonstrating the strong potential of this technique for studying catalyst deactivation due to coking.
New insights into 3D-printed materials for future fusion reactors
X-ray and neutron experiments give valuable clues.
When Tungsten Meets Steel: Designing Interfaces for Fusion
Additive manufacturing enables new tungsten–steel designs for fusion reactors—but also creates complex microstructures. PSI researchers reveal how phases form and evolve at the interface during processing.
LEAPS AISBL inaugurated in Brussels as formal legal entity
Europe’s leading photon science facilities enter a new phase of strategic coordination.
Not every brain ages in the same way
Over a lifetime, our brain ages – in particular its volume decreases. However, the brains of some people display a greater resistance to age-related change and to the protein deposits associated with dementia.
