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.

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.

For the development of new medicinal agents, accurate knowledge of proteins is crucial. In a pilot experiment, researchers have now, for the first time, used the X-ray free-electron laser SwissFEL of PSI for the examination of protein crystals.

Gebhard Schertler is head of the research division Biology and Chemistry at the Paul Scherrer Institute PSI and professor for Structural Biology at ETH Zurich. In this interview he talks about biological research at PSI and the future of drug development.

Researchers from the Paul Scherrer Institute PSI, the University of Basel and Roche have used neutron imaging to investigate why cool storage is crucial for syringes pre-filled with a liquid medication.

The 16th of May is the International Day of Light. The research carried out with light at PSI enables advances in biology and pharmacology and also promotes the development of new materials for data storage and new technologies for personalised medicine.

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.

Nowhere in the world have so many ocular tumours been irradiated with protons as at PSI. But before the affected patients go to Villigen, they have to visit Lausanne: for pretreatment at the Jules Gonin Ophthalmic Hospital. The more than 30-year-long collaboration between the hospital and PSI is unique, and in most cases it saves the patient's diseased eye.

A spin-off from PSI has received this year's Swiss Technology Award: The young company GratXray is developing a new method for early diagnosis of breast cancer.

With a new method for modifying antibodies, Philipp Spycher, winner of a Founder Fellowship at the Paul Scherrer Institute PSI, wants to develop drugs that are more stable and, thus, have fewer side-effects.

With the new Founder Fellowship, the Paul Scherrer Institute PSI gives young researchers the chance to become entrepreneurs. Within 18 months they have to demonstrate the commercialisation potential of their business ideas and draw up an initial business plan. Today the official ceremony awarding this grant took place: The first three prize winners are working on a new pharmaceutical technology, a nano-energy technology, and a neutron detector.

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.

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.

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.

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.

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.

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.

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.

Doctors had discovered, behind Gabi Meier’s right eye, a tumour that surrounded the optic nerve. Only at the PSI was there still one possibility to treat the tumour in such a way as to preserve neighbouring structures and the eye. A few months after the proton treatment was over, I realised that I could see more and more, she said in an interview. “Just dimly, it’s true, but I could see! That was sensational!”
