A genetic analysis of 493 tumors from domestic cats collected across five countries found that feline cancers share many of the same cancer-driving genes seen in people and dogs, including frequent FBXW7 mutations in feline mammary tumors that are linked to poorer outcomes in some human breast cancers. The results were published in Science.

A study of 440 participants from the Women’s Interagency HIV Study found that accelerated epigenetic aging in monocytes—an immune cell type—tracked more closely with emotional and cognitive depression symptoms such as hopelessness and loss of pleasure than with physical symptoms like fatigue. The work, published in The Journals of Gerontology: Series A, adds evidence that cell-type-specific aging measures could contribute to future biological tools to complement symptom-based depression screening, though researchers say more validation is needed before clinical use.

Researchers at Mayo Clinic have discovered a rare mutation in the MET gene that directly causes metabolic dysfunction-associated steatotic liver disease, a condition affecting about one-third of adults worldwide. The finding, based on a family case without typical risk factors, suggests similar variants may contribute to the disease in many others. Published in Hepatology, the study highlights the role of genomic analysis in uncovering hidden genetic causes.

Scientists have developed a light-based sensor that can identify tiny amounts of cancer biomarkers in blood samples, potentially enabling earlier detection than traditional scans. The technology combines DNA nanostructures, CRISPR, and quantum dots to produce a clear signal from just a few molecules. Tests on lung cancer patient serum showed promising results at sub-attomolar levels.

Researchers in Brazil have uncovered how pancreatic cancer uses a protein called periostin to invade nerves and spread early. This discovery explains the disease's aggressiveness and suggests new treatment targets. The findings, published in Molecular and Cellular Endocrinology, highlight the tumor's ability to remodel surrounding tissue.

MIT researchers have invented a swallowable pill that signals when medication is taken, aiming to combat poor adherence rates among patients. The device uses a biodegradable antenna to transmit a wireless confirmation shortly after ingestion. This innovation could benefit high-risk groups like organ transplant recipients and those with chronic infections.
