Two decades after a breast cancer vaccine trial, every participant is still alive—an astonishing result for metastatic disease. Scientists found their immune systems retained long-lasting memory cells primed to recognize cancer. By enhancing a key immune signal called CD27, researchers dramatically improved tumor elimination in lab studies. The findings suggest cancer vaccines may have been missing a crucial ingredient all along.

Scientists at Mount Sinai have unveiled a bold new way to fight metastatic cancer by turning the tumor’s own defenses against it. Instead of attacking cancer cells head-on, the experimental immunotherapy targets macrophages—immune cells that tumors hijack to shield themselves from attack. By eliminating or reprogramming these “bodyguards,” the treatment cracks open the tumor’s protective barrier and allows the immune system to flood in and destroy the cancer.

Collagen pills sound like a shortcut to younger skin, but solid evidence doesn’t back them up. Higher-quality studies show little benefit, and your body doesn’t absorb collagen in the way ads suggest. Some supplements may even pose safety concerns and lack proper testing. Experts recommend focusing on proven habits like sunscreen, retinoids, and a nutrient-rich diet instead.

An experimental drug once known for helping control type 2 diabetes may also fight heart disease. Researchers found IC7Fc lowered cholesterol, blood fats, and artery-clogging plaques while calming inflammation linked to heart attacks and strokes. Notably, these benefits appeared even without weight loss, suggesting the drug could help lean people at risk of heart disease.

Scientists in Sweden and Norway have uncovered a promising way to spot Parkinson’s disease years—possibly decades—before its most damaging symptoms appear. By detecting subtle biological signals in the blood tied to how cells handle stress and repair DNA, the team identified a brief early window when Parkinson’s quietly leaves a measurable fingerprint.
