The role of aerosols in the Coronavirus pandemic
It now seems certain that Covid-19 can be transmitted via airborne particles. But how are these particles produced? How quickly can transmission occur and how can we protect ourselves? PSI aerosol researcher Urs Baltensperger summarises the most important facts on this issue.
Which particulate air pollution poses the greatest health risk?
The composition of particulate matter can influence its harmfulness to human health just as much as the amount, PSI researchers show in a newly published study. Experiments and computational modelling showed that in Europe high concentrations of particulate matter harmful to human health occur mainly in metropolitan areas.
Wait and see, and grow crystals
At PSI, researchers decipher the structure of the proteins in bacteria and viruses. This knowledge can aid, for example, in the development of drugs against infectious diseases. But before the investigation can begin, an extremely tricky problem has to be solved: the crystallisation of the molecules.
A protein's unexpected "doming"
Researchers have coaxed a secret out of the vital protein cytochrome c that it kept well-hidden up to now. Measurements at the X-ray free-electron laser SwissFEL reveal structural changes that science had previously ruled out for this kind of biomolecule.
More effective treatment of thyroid cancer
PSI researchers have found a more effective treatment for a form of thyroid cancer – and with fewer side effects – by increasing the uptake of the cancer drug in tumour cells. The results have been published in the medical journal Theranostics.

Priority research continues
The Paul Scherrer Institute PSI is in limited operation due to the Covid-19 pandemic, and most employees are working from home in accordance with the Federal Council's specifications. Nevertheless, essential research facilities and projects continue to operate in accordance with all the necessary safety precautions.
"We want to understand how this virus works"
The Swiss Light Source SLS at PSI is still in operation despite the Covid-19 pandemic – and may be urgently needed, especially in these difficult times. Oliver Bunk, head of the Laboratory for Macromolecules and Bioimaging, explains why.

Researchers at the Paul Scherrer Institute PSI have an important part of the regulatory cycle that is involved in the formation and degradation of the cytoskeleton. Among other things, they have watched molecular scissors at work.
Bringing information into the cell
Researchers at the Paul Scherrer Institute PSI have elucidated an important part of a siganalling pathway that transmits information through the cell membrane into the interior of a cell. This exists in all mammals and plays an important role, among other things, in the regulation of the heartbeat. The new findings could lead to new therapies.
Children are her passion
At PSI, Beate Timmermann built up a programme providing proton therapy for children with cancer at the same time she was raising her own son. Today she is head of the Clinic for Particle Therapy at the West German Proton Therapy Centre in Essen (WPE) and is considered one of the most accomplished experts in this field.
Licence agreement with Swiss pharma firm for development of a cancer drug
A radioactive agent, developed at the Paul Scherrer Institute PSI to fight an especially malignant form of thyroid cancer, has the potential to become a blockbuster drug. Due to its structure, it might also be able to dock onto cells of other tumours and destroy them with its radiation. The Lausanne-based biopharmaceutical company Debiopharm wants to further develop the PSI agent to the point where it is approved as a drug. Debiopharm and PSI have now created the contractual basis for this.

Opening: Advanced technology against cancer
With proton therapy, certain tumours can be irradiated with exceptional precision – while, the surrounding healthy tissue is optimally protected. In Switzerland, this kind of radiation therapy is only possible at PSI. In a joint project with the University Hospital Zurich and the University of Zurich, PSI has expanded its capacity with a state-of-the-art treatment facility: the new, 270-ton Gantry 3.
Testing the Limits for the Patients' Benefit
Proton therapy is already a success story at the Paul Scherrer Institute PSI but researchers remain dedicated to making treatment faster and safer.

When small children develop cancer, the whole family is affected. Staff at the Paul Scherrer Institute PSI’s Centre for Proton Therapy combine target-oriented proton beam irradiation and a caring, warm-hearted atmosphere to help these children.
Getting a Handle on Safety
Proton beams don’t just cure cancer. They can also damage healthy tissue. To make sure that this doesn’t happen, PSI’s Centre for Proton Therapy carries out over 350 safety tests a year. The results speak for themselves: several thousand patients have undergone proton irradiation treatment here in Villigen. There’s never been an accident.
Rays of hope for patients
For over 30 years, patients with a particular form of ocular tumour have been treated at PSI by means of proton irradiation. The tiny particles hit their target with millimetre precision, without endangering other structures of the eye. The irradiation facility OPTIS, developed at the PSI Center for Proton Therapy of the PSI, is a success story, considering that for more than 90 percent of the patients treated to date, the eye could be saved.
In start-up companies, getting it done is a matter of survival
A pharmaceuticals manager at Roche for a long time, now he is the founder of a biotech firm on the campus of the Paul Scherrer Institute PSI: Michael Hennig knows the trends in the medical sector. In this interview he explains why the medicine of the future needs the innovation power of publicly funded research, and why he chose to locate his start-up leadXpro so close to PSI.
In cold water
Martin Ostermaier wanted to break out of the comfort zone of science. Now, instead of pipettes, the biochemist is dealing with investors and patent law.
Added value for cancer patients
At the Paul Scherrer Institute PSI, cancer patients receive a treatment that is unique in Switzerland: proton therapy. This state-of-the-art form of radiation therapy against cancer has major advantages, compared to conventional irradiation, in terms of effectiveness and side-effects. The PSI has its own Center for Proton Therapy dedicated to this special treatment. Its pioneering work has not only helped several thousand patients, but also has fundamentally changed proton therapy worldwide.
In the focus of the protons
At the PSI, researchers work with radioactivity every day in order to develop advanced treatment methods for patients. Naturally, they take special safety precautions working with a material that decays. It's a race against time. To make sure everything functions smoothly, a dedicated work group takes care of the infrastructure.
