Radiation is a form of energy released in the form of rays, particles, or waves. It can be found all around us, from the sun and stars, to man-made sources like cell phones, computers, and nuclear power plants. Radiation can be both beneficial and harmful. It can be used to diagnose and treat illnesses and diseases, or it can cause long-term health problems such as cancer. On this page, you can find the latest news, articles, and videos about radiation and how it affects us.
How does UV radiation (UVR) break disulfide bonds? Disulfides bonds are found across all domains of life yet this question has remained unanswered for decades. Our research uses X-ray free electron lasers to uncover the earliest steps in the interaction between UVR and the L-cystine disulfide bond.
Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, and very high concentrations of carbon dioxide in the atmosphere. Yet, under these conditions, biofilms formed and within these dense, slimy conditions, exciting things were happening.
Coelacanths are strange fish that are currently only known from two species found along the East African coast and in Indonesia. A team from the Natural History Museum (MHNG) and the University of Geneva (UNIGE) has succeeded in identifying an additional species, with a level of detail never before achieved. This discovery was made possible by the use of the European Synchrotron Radiation Facility (ESRF) in Grenoble, a particle accelerator for analyzing matter.
