Catching Cancer: Blood Test for Early-Stage Diagnosis

What is the difference between a normal cell and a cancer cell? The answer lies in their DNA. Cancer results from the accumulation of genetic mutations, which trigger uncontrolled cell growth. Cancer’s mutated DNA can reveal its presence early on in the disease. Like leaving fingerprints at a crime scene, tumor cells release small pieces of DNA into the bloodstream. This “circulating tumor DNA” can now … Continue reading Catching Cancer: Blood Test for Early-Stage Diagnosis

The Single Cell Revolution: Zooming into human health & disease

by Eric P. Grewal figures by Abby Burrus The human body is made of thousands of types of cells, from neurons to blood cells and skin cells to kidney cells. While these cells differ vastly in shape and purpose, they all share one thing in common—their DNA, the set of “master instructions” that is carried in every cell in an individual. But if all cells … Continue reading The Single Cell Revolution: Zooming into human health & disease

Strength in Numbers: genetic sequencing of large populations is shaping the future of medicine

by Ryan L. Collins figures by Brad Wierbowski Thanks to modern genetics, “precision medicine” is slowly becoming a reality: doctors can perform genetic tests to determine your risk for dozens of diseases, like stroke or liver disease, and can prescribe treatments or therapies tailored to your individual genetic makeup. Yet before doctors can provide you with precision medicine in practice, they first need to understand … Continue reading Strength in Numbers: genetic sequencing of large populations is shaping the future of medicine
