A new study from Scripps and the biotech Gero demonstrates that artificial intelligence can be used not just to accelerate drug discovery, but to fundamentally transform how it’s done—by targeting the full complexity of biological aging.

Researchers at the National Institutes of Health (NIH) have identified a series of changes in the architecture and cell composition of connective tissues of the breast, known as stromal tissue, that is associated with an increased risk of developing aggressive breast cancer among women with benign breast disease, and poorer rates of survival among women with invasive breast cancer. This process, which they call stromal disruption, could potentially be used as a biomarker to identify women with benign breast disease who are at high risk of developing aggressive breast cancers, as well as those with breast cancer who may be at increased risk of recurrence or death.

Evidence of a unique T cell may explain why urban children are more prone to allergies than rural children. Differences in the development of the gut microbiome may be an underlying cause.
