A surprising new study suggests that when it comes to pancreatic cancer, the kind of fat you eat may matter more than how much. Researchers found that oleic acid—the main fat in olive oil and several other common foods—sped up tumor growth in mice predisposed to pancreatic cancer, while omega-3-rich fats from fish oil dramatically slowed disease development.

A Salk Institute study found that a simple dietary amino acid, methionine, dramatically improved survival in mice facing severe infections and inflammatory conditions. Rather than directly targeting the immune system, methionine boosted kidney filtration, helping the body flush out excess inflammatory molecules that can cause tissue damage, brain dysfunction, wasting, and death.

A promising new study suggests rheumatoid arthritis may not be as inevitable as once thought for people at high risk. Researchers found that just one year of treatment with the immune-targeting drug abatacept delayed the onset of rheumatoid arthritis by up to four years, with benefits lasting long after treatment ended.

A long-overlooked organ may hold surprising clues to healthy aging and cancer survival. Researchers at Mass General Brigham used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses—a small immune-system organ once thought to become largely irrelevant after childhood—lived longer and had substantially lower risks of heart disease, cancer, and death.

Benign prostatic hyperplasia (BPH), prevalently in aging men, is characterized by aberrant cell death of prostate cells. Anoikis, a specific subtype of apoptosis, is triggered when cells detach from the extracellular matrix (ECM), in contrast, cells with anoikis resistance contribute to pathological processes such as unregulated cell proliferation and impaired cell death. However, the role of anoikis resistance in BPH pathogenesis remains poorly understood. In this study, an elevated anoikis...

Anxiety disorders are prevalent and can greatly impact well-being. The biological mechanisms behind anxiety are not fully understood, but growing evidence suggests a role for DNA methylation. Here, we conduct a large-scale methylome-wide association study of lifetime anxiety in 14,443 participants (1817 cases and 12,626 controls) in whole blood, and, through epigenomic deconvolution, 12 different blood cell types. We detect four CpG associations at methylome-wide significance in whole blood, and...
