Immunotherapy unleashes the power of the immune system to fight cancer. However, for some patients, immunotherapy doesn't work, and new research may help explain why. When immune cells called T lymphocytes infiltrate malignant tumors, the genetic program of those T cells and the developmental path they then follow, may affect their response to immunotherapy and predict overall patient survival, according to a new study. The results overturn the prevailing model of immune responses in melanoma and present different therapeutic approaches.

To provide a convenient tool for the early detection of injuries, researchers have developed a portable MRI device for diagnosing cartilage damage in the wrist. Using this device, the researchers imaged the wrists of tennis players at a tennis school. Several athletes were found to have cartilage damage without any other symptoms of an injury. Thus, this device provides a convenient early screening tool to help prevent further injury or damage.

Young adults who were at risk of food insecurity had increased incidence of diabetes 10 years later, according to a new study. While previous research has associated food insecurity with a range of health issues including diabetes, obesity and hypertension, this study showed a connection over time, suggesting a causal relationship. Researchers analyzed data on nearly 4,000 people from the National Longitudinal Study of Adolescent to Adult Health. They found that adults ages 24-32 who said they'd been worried about food running out in the last year showed greater incidence of diabetes, either through blood glucose tests or self-reports, at ages 32-42, compared to those who did not report food insecurity risk.
