A blood test is shown to better detect lung cancer in the Early Detection of Cancer of the Lung Scotland trial. As lung cancer presents late in the disease, early detection could save lives.

Autophagy is influential on aging, as many of the interventions capable of slowing aging in animal models involve increased autophagy. Better maintenance of cells means better tissue function and slower onset of age-related dysfunction.

Telomerase 'immortalizes' cancer cells, prevents tumors and slows a key stage in normal cell death. A new study found that telomerase reactivates in normal adult cells at a critical point in the aging process.

Fat tissue surrounding skeletal muscle contributes to declining muscle mass and strength. The most compelling evidence arises from transplantation of fat tissue between mice, showing that it produces harmful effects.
