Colorectal cancer is the second leading cause of cancer death worldwide. If detected early, it can be efficiently treated, but the cost and discomfort of colonoscopies—the main diagnostic method currently in use—often result in delayed diagnosis.

Researchers at Karolinska Institutet, KTH Royal Institute of Technology and SciLifeLab have developed a new method for detecting early signs that the disease type 1 diabetes is going to develop. The study, conducted in an experimental model, shows that analyzing tiny amounts of blood can reveal disease-causing changes in the body, thereby enabling early treatment and disease prevention. The results have been published in the journal Diabetologia.

New research from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) demonstrates the accuracy of modern radiotherapy techniques used to treat cancer. The study is published in the Journal of Applied Clinical Medical Physics.

A genetically modified pig lung remained viable and functional over a period of 9 days after being transplanted into a human recipient who had been declared brain dead, according to research published in Nature Medicine.
