Chemotherapy kills cancer cells. But the way these cells die appears to be different than previously understood. Researchers have now uncovered a completely new way in which cancer cells die: due to the Schlafen11 gene. 'This is a very unexpected finding. Cancer patients have been treated with chemotherapy for almost a century, but this route to cell death has never been observed before. Where and when this occurs in patients will need to be further investigated. This discovery could ultimately have implications for the treatment of cancer patients.'

Abnormalities in the shape of the sclera, the white of the eye, can cause various complications and lead to blindness. However, techniques to observe the sclera in detail, such as its fibrous structure, are lacking. Now, researchers have used polarization-sensitive optical computed tomography to accurately visualize the density and orientation of scleral fibers in the eyes of living patients, opening doors to understanding ocular pathologies better and developing effective diagnostic and therapeutic strategies.

Prions are the abnormal, pathogenic agents that are transmissible and are able to induce abnormal folding of specific normal cellular proteins. Prion disease is an umbrella term for a group of fatal and currently untreatable neurodegenerative diseases that not only affect humans, but also wild and captive animals. These diseases include Creutzfeldt-Jakob disease (CJD) in humans, bovine spongiform encephalopathy (BSE, or 'mad cow disease'), and chronic wasting disease (CWD) affecting deer, elk and moose.
