From a quarter of a lap to a million – it takes a whole team to perfectly bring electrons back to the storage ring at the Swiss Light Source SLS.

What do concrete, catalysts and the description of the world have in common? They are at the focus of three PSI research projects that will be funded over the next five years by grants from the Swiss National Science Foundation SNSF.

New research shows that microtubule plus-end tracking proteins (+TIPs) self-organize into fluid fractal networks! These structures help position the nucleus for cell division—combining flexibility with strength. 📖 Read more: #ResearchAtPSI

Researchers at the PSI Center for Life Sciences have shown how botox enters nerve cells. This could enable a more effective use of the toxin, for example in pain therapy. #ResearchAtPSI #Biology #Medicine #HealthInnovation .

PSI physicists have teamed up with Google to build a new type of digital-analogue #quantum #simulator that can be used to study physical phenomena with unprecedented precision and flexibility.

🎉 After months of hard work, and with electrons finally back at SLS, we took a moment to celebrate the expertise and dedication of the incredible team behind the SLS 2.0 upgrade, underway since September 2023. Here are some highlights from the “Bright Times” party!

An international group of researchers led by PSI, has found strong evidence of spinons exotic particles, which are key to understanding new quantum phenomena. Using neutron scattering techniques, they observed features that match theoretical predictions.

23 January 2025 - a day to remember: The electrons are back at the #SwissLightSource #SLS! 💫. With this, SLS is well on track to resume operation in summer 2025. Congratulations to the entire #SLS 2.0 team on this major milestone! 👏. #UpgradingSLS #LightSourceScience

Researchers at PSI and @leadXpro have leveraged a photoswitchable caffeine derivative to study ligand dissociation from a G protein-coupled receptor. This breakthrough is a crucial step in advancing our understanding of drug-receptor interactions.

Driving long distances without recharging? This requires more powerful electric car batteries. Researchers at PSI have discovered how their energy density can be increased. Their trick: a new sustainable coating method for the cathode material.

Network, supply, power and fibre optic cables – the #SLS2.0 upgrade requires hundreds of kilometres of newly laid cables. How PSI’s Electrical Installations Section mastered this task:.

🎄✨ O Christmas Tree, O Science Tree! This SEM #SciencePic shows nanostructures resembling a forest of Christmas trees. Captured by XRnanotech, a PSI spin-off, it’s our final festive post. Wishing you a joyful holiday season! ❄️

🤩Absolutely amazing! The discovery of a new type of magnetism, termed altermagnetism, at the #SwissLightSource #SLS has been recognised by Science as one of the top 10 scientific breakthroughs of 2024!

📩 PSI users: our quarterly Facility Newsletter is out! Get important information, an overview of the latest scientific highlights, upcoming calls for proposals and news from the PSI facilities: SLS, SINQ, SμS, CHRISP and SwissFEL.

A boost for cutting-edge #ResearchAtPSI: Funding for the IMPACT project is ensured. ✨ This means: 10 billion #muons per second for research as well as the most powerful facility worldwide for medically relevant #radionuclides.

❄️ Let it snow! This #SciencePic shows a laser-made snowflake design on a 2-nm magnetic film. The laser alters the film’s properties, controlling where magnetization flips under a magnetic field. A Kerr microscope reveals these changes. Science meets the season!
