Apply the ointment, light on, light off – that’s how easy it is to cure various forms of non-melanoma skin cancer.
Cells that are incubated with aminolevulinic acid form protoporphyrin IX (PpIX), which appears red on the fluorescence micrograph. Both nerve cells (top row), and skin cancer cells (bottom row) form PpIX. The image on the left of both rows represents an overview, the images in the middle and on the right show enlarged sections of the images on the left. The power plants of the nerve and cancer cells, the mitochondria, are coloured green. The colour pattern of PpIX and the mitochondrial dye are similar. This suggests that PpIX accumulates in the mitochondria. Image: Ben Novak
However, the majority of patients suffer severe pain during the so-termed photodynamic therapy. Why the treatment with ointment and red light can be so painful has now been uncovered by researchers from the RUB.They identified the ion channels involved and signalling molecules secreted by the cancer cells. “The results may provide a starting point for suppressing the pain”, says Dr. Ben Novak of the Department of Animal Physiology.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
