World first: Doctors use ‘reprogrammed’ stem cells to repair cornea

Scientists in Japan have, for the first time, treated a damaged cornea using induced pluripotent stem cells. According to the surgeon, the person’s vision has improved since the procedure. The cornea covers the front section of the eye, including the iris and pupil. Scientists create induced pluripotent stem (iPS) cells by reprogramming adult cells. This […]

Using artificial intelligence to predict mortality

Using artificial intelligence to predict mortality

New research that appears in the journal PLOS ONE suggests that machine learning can be a valuable tool for predicting the risk of premature death. The scientists compared the accuracy of artificial intelligence prediction with that of statistical methods that experts are currently using in medical research. New research suggests that healthcare professionals should use […]
