Colon Screening Intervals, New Cancer Drugs, and Ancient DNA

Today we cover three major New England Journal of Medicine trials on colonoscopy surveillance intervals, a new antibody drug conjugate for small cell lung cancer, and blinatumomab replacing chemotherapy in pediatric leukemia. We also look at a new quality control system for glycogen in the brain, stroke recurrence after artery dissection, and what ancient DNA reveals about migration through Central Asia. A quick rundown covers viral hijacking of host cells, a cholesterol sensing protein, and more.
