Mindfulness may lower blood pressure in just 8 weeks
Mindfulness, gratitude, and optimism training may improve blood pressure, inflammation, and other heart-health measures within just eight to 12 weeks. The strongest programs paired daily practice with regular reinforcement, suggesting that improving psychological well-being could become another tool for protecting cardiovascular health.
Reaching 90 without dementia doesn’t mean you’re in the clear
A study of people over 90 found that dementia risk remains strongly shaped by sex, race and genetics, with women and black participants facing notably higher risks. Intriguingly, some people stayed cognitively healthy despite carrying major risk factors, potentially offering clues to how the brain can resist dementia deep into old age.
Reactive agility and motor-cognitive assessments for distinguishing community-dwelling older adults with and without a history of falls: a dual-centre cross-sectional study
Although motor and cognitive functions are closely interconnected in daily life, they are typically assessed separately in fall assessments. This dual-center cross-sectional, observational study examined the discriminative performance of agility and motor-cognitive assessments to distinguish between community-dwelling older adults with and without a history of falls, compared with established motor and cognitive tests. A total of 231 participants (103 with a history of falls; age 71.9 ± 7.5...
MGRN1 preserves transiently damaged mitochondria for antioxidant-mediated repair
Mitochondria are continuously exposed to damage that contributes to aging and disease. While prolongedly damaged mitochondria are eliminated by mitophagy, how cells respond to transient damage remains unclear. Here, we establish a cell-based system to induce transient mitochondrial stress and resolve its recovery dynamics. We identify the E3 ubiquitin ligase mahogunin ring finger 1 (MGRN1) as a damage-threshold sensor that discriminates between transient and prolonged mitochondrial insults....
