Researchers unlock cell density as a tool for building synthetic tissues

Genes aren't the sole driver instructing cells to build multicellular structures, tissues, and organs. In a new paper published in Nature Communications, USC Stem Cell scientist Leonardo Morsut and Caltech computational biologist Matt Thomson characterize the influence of another important developmental driver: cell density, or how loosely or tightly cells are packed into a given space.

Study identifies DNA collisions driving genetic changes in cancer

Cancer researchers at the University of Chicago and the University of California, San Francisco (UCSF) have discovered that mutations in certain genes can lead to the accumulation of DNA errors, resulting in a specific type of genetic change known as large tandem duplications (TDs) that can arise from the collision of two critical cellular processes: transcription and DNA replication.

Coronary artery calcium scores found to predict risk of heart attack and death in both men and women

Coronary artery calcium (CAC) scores have become a non-invasive way for physicians to easily determine how much plaque has built up inside a patient's coronary arteries, but the question has been how accurate the score is in identifying women, as well as men, who are at high risk for a heart attack or death.
