Most solid tumors become stiff as the cancer progresses. Although researchers recognize that the environment around the cancer cells influences their behavior, it is unclear how it does so. In a new paper, published in Scientific Data, researchers from the University of Illinois Urbana-Champaign have collected gene expression data in response to mechanical stiffness in tumors. Their work can help guide our understanding of the crosstalk between cancer cells and their surroundings.

Studies indicate that homemade masks help combat the spread of viruses like COVID-19 when combined with frequent hand-washing and physical distancing. Many of these studies focus on the transfer of tiny aerosol particles; however, researchers say that speaking, coughing and sneezing generates larger droplets that carry virus particles. Because of this, mechanical engineer Taher Saif (M-CELS/RBTE) said the established knowledge may not be enough to determine the effectiveness of some fabrics used in homemade masks.
