Microplastics discovered in prostate tumors

Small fragments of plastic were found in 9 out of 10 patients with prostate cancer, and in higher levels inside tumors than in nearby noncancerous tissue, a new study finds. The small, single-center study was led by researchers ...

AI decodes tissue characteristics of type 2 diabetes

Researchers from several partner institutions of the German Center for Diabetes Research (DZD) have collaborated with international colleagues to develop a new approach for visualizing subtle tissue changes in the pancreas ...

Brain may reinforce seizures during sleep, suggests study

The brain may inadvertently "learn" to have seizures by treating them like important memories to be stored, according to new research from Mayo Clinic. The study, published in the Journal of Neuroscience, has found that after ...

You don't need to be very altruistic to stop an epidemic
