PSI Founder Fellowship for AI platform and solid-state batteries
PSI researchers Mohsen Sadr and Mohammadhossein Montazerian are receiving financial support and guidance for their business ideas through the PSI technology transfer team.
Surgery for quantum bits
Researchers show how quantum operations can be carried out while actively correcting errors – a key step toward reliable quantum computers.
One thousand modules for CERN
At CERN near Geneva, tiny particles with extremely high energies are blasted at each other to answer big questions about the universe. The detectors that observe the collisions of these particles require regular upgrades. Lea Caminada and her High Energy Particle Physics research group at PSI play an important role in this quest.
Important funding for muon research
PSI gets an NCCR: The Muoniverse project will further expand research on the beamlines for elementary particles called muons – at the world’s leading facility for muon beams.
“We’re pulling out all the stops”
PSI is increasing the intensity of its muon beams a hundredfold. This opens up entirely new possibilities for physics and materials research.
Identifying the sources of Sarajevo’s smog
Fumes from wood and coal burning as well as from cooking are the main sources of the heavy smog in the capital of Bosnia and Herzegovina. That’s the finding of a comprehensive mobile measurement campaign by PSI researchers.
A comprehensive energy system model for Switzerland
Energy systems face complicated, long-term challenges with a high degree of uncertainty. To explore these challenges and support decision-making, the STEM energy systems model from the Energy Economics Group at PSI has become a key tool.
Swiss X-ray laser reveals the hidden dance of electrons
New X-ray technique at SwissFEL shows how electrons act together – with the potential to show why quantum information slips so easily away.
Electric vehicles could catch on in Africa sooner than expected
Electric vehicles could become economically competitive in many African countries before 2040.
X-raying auditory ossicles – a new technique reveals structures in record time
Using a bone, PSI researchers have demonstrated how the structures of biological materials can be determined on scales from nanometres to millimetres in a very short time.
New process for stable, long-lasting all-solid-state batteries
PSI researchers have developed a novel process that could make all-solid-state batteries more robust and longer-lasting.
Synchronising ultrashort X-ray pulses
Attosecond coherent pulses at SwissFEL will open new experimental possibilities
PSI Year in Review 2025
Twelve PSI research highlights in 2025
Engineering skill and perseverance
Credit for the on-time completion of the major SLS 2.0 upgrade project is due in part to a team of dedicated electrical engineers.
Kelvin: The low-temperature scale
The art of engineering means, first of all, the skill required to design and manufacture devices that enable top technical performance. This gallery shows, in five pictures, that this term can also be understood differently if the devices are regarded as works of art with their very own aesthetic, apart from their actual function.
“Collaboration is particularly important in quantum research”
PSI researcher Kirsten Moselund talks about quantum technologies – about their importance and the current situation in Switzerland. And about her own research in the field of nanophotonics.
Laser draws made-to-order magnetic landscapes
Researchers at PSI have found a surprisingly inexpensive and fast method to make localised alterations in magnetic materials.
How microtubules take part in cellular signal processing
Researchers at PSI have investigated on the molecular level how the cytoskeleton transmits commands within the cell. Their findings could provide the medical field with new options for intervention in the event of malfunctions within the organism.
Optimising the treatment of eye tumours
The Insel Group and PSI are expanding their collaboration to provide faster and better coordinated access to proton therapy for patients with eye tumours.
Predicting component lifetimes in nuclear facilities
For 30 years, experiments have been providing unique insight into how metals and ceramics degrade under high-energy proton bombardment.
X-rays bring high-resolution brain mapping within reach
A new imaging breakthrough could reveal brain connectivity in 3D detail never before accessible.
Clean biogas – measurable everywhere
A new analytical method can detect even tiny amounts of critical impurities.
Swiss PIC technology transfer centre is inaugurated
Jointly founded by scientific and industrial partners with PSI researchers: the Swiss Photonics Integration Center celebrated its inauguration on 24 November 2025.
How the cheese-pasta principle could help counter Alzheimer's
PSI researchers have discovered cellular mechanisms that could help to mitigate diseases such as Alzheimer's and Parkinson's.
Atoms under pressure
Zurab Guguchia puts pressure on matter – and in doing so, creates exciting quantum effects such as superconductivity at more easily achievable temperatures.
Electric cars and heat pumps can help the Energy Strategy
In future, flexibly operated heat pumps and electric cars could reduce both electricity imports and electricity prices. That is according to a new study by a Swiss research consortium led by ETH Zurich.
Terbium duet and other quantum art
To create more stable qubits, PSI researchers make terbium ions perform in pairs. Elsewhere, they are using optical tweezers to position atoms with high precision.
Particulate pollution re-evaluated
A new study provides data from 43 sites across Europe, showing the respective oxidative stress on the lungs.
Slowing time and trapping ions
Cornelius Hempel uses quanta to perform calculations on quantum phenomena. While this sounds logical, it’s actually highly complex. His latest coup: a quantum simulator that slows down time.
Disorder begins at the surface of quantum materials
Ultrafast X-rays from SwissFEL reveal unexpected light responses in quantum materials.
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.
