Here are some illuminating scientific discoveries from the week to help you live better and maybe even see a baby tortoise.
Blood test could detect cancer three years earlier. Tumors shed genetic material that can show up in a person’s bloodstream months to years before they’re diagnosed with cancer, according to a new Johns Hopkins study. When analyzing the blood samples of 26 patients who were diagnosed with cancer within six months of blood collection, the researchers detected tumor DNA in eight people (or 31% of the time). The team also had three-year-old blood samples on hand for six of those eight people, and microscopic cancer mutations were detected in four of them. The discovery paves the way for early intervention at a time when tumors are “more likely to be curable,” one of the study’s authors said.—ML
