Younger adults face growing colorectal cancer risk
Colorectal cancer has overtaken other cancers to become the leading cause of cancer death in adults under 50, with cases continuing to rise at an alarming rate. Researchers identified key warning signs that younger adults should not ignore: persistent changes in bowel habits, recurring rectal bleeding, dark or narrow stools, and unexplained weight loss. The trend has prompted calls for lowering the recommended screening age from 45 to 40 for certain high-risk groups.
Alzheimer's defense protein discovered
Scientists identified a protein called SORLA that may act as a powerful defense against the toxic tau tangles involved in Alzheimer's disease. Mice with extra SORLA showed less tau accumulation, less brain atrophy, and healthier connections between neurons, while those without it experienced more severe damage. The finding opens a possible drug target that could help slow or prevent Alzheimer's progression.
AI blood test predicts heart disease 15 years early
Researchers developed an AI-powered blood test called CardiOmicScore that can estimate the risk of six major cardiovascular diseases — including heart attack, stroke, heart failure, and atrial fibrillation — up to 15 years before symptoms appear. The test analyzes thousands of proteins and metabolites, offering far earlier warning than traditional risk assessment methods.
