Why is this a problem? 'If I run a sample and it has fentanyl, I want to be sure that fentanyl came from the sample and not from background levels in my lab,' said a researcher.

Hyper-Mutating Tumor Suppressor RNAs In Leukemia

Writing in the January 3 issue of Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of "copy editing" by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and represent a new therapeutic target for preventing cancer cell resistance to chemotherapy and radiation.

Advances in Artificial Intelligence Threaten Privacy Of People's Health Data

Advances in artificial intelligence have created new threats to the privacy of people's health data , a new University of California, Berkeley, study shows. Led by UC Berkeley engineer Anil Aswani, the study suggests current laws and regulations are nowhere near enough to keep an individual's health status private in the face of AI development.
