Daily exposure to blue light may accelerate aging, even if it doesn’t reach your eyes

Prolonged exposure to blue light, such as that which emanates from your phone, computer and household fixtures, could be affecting your longevity, even if it’s not shining in your eyes. New research suggests that the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas, according to a new study […]

New gene editing technology could correct 89% of genetic defects

(CNN) Scientists have developed a new gene-editing technology that could potentially correct up to 89% of genetic defects, including those that cause diseases like sickle cell anemia. The new technique is called “prime editing,” and was developed by researchers from the Broad Institute of MIT and Harvard, who published their findings Monday in the journal […]

Owning a Dog May Add Years to Your Life, Study Shows

In a 2019 study entitled Dog Ownership and Survival, A Systematic Review and Meta-Analysis, dog ownership has been linked with decreased cardiovascular risk. Recent reports have suggested an association of dog companionship with lower blood pressure levels, improved lipid profile, and diminished sympathetic responses to stress. However, it is unclear if dog ownership is associated […]

Scientists Have Found Longevity Biomarkers

A group of scientists from Skoltech, Moscow State University and Harvard University decided to fill this gap and identify crucial molecular processes associated with longevity. To do so, they looked at the effects of various lifespan-extending interventions on the activity of genes in a mouse, a commonly used model organism closely related to humans.

‘Stressors’ in middle age linked to cognitive decline in older women Johns Hopkins Medicine

A new analysis of data on more than 900 Baltimore adults has linked stressful life experiences among middle-aged women — but not men — to greater memory decline in later life. The researchers say their findings add to evidence that stress hormones play an uneven gender role in brain health, and align with well-documented higher […]

A meta-analysis of genome-wide association studies identifies multiple longevity genes

“We performed a genome-wide association study of longevity-related phenotypes in individuals of European, East Asian and African American ancestry and identified the APOE and GPR78 loci to be associated with these phenotypes in our study. Moreover, our gene-level association analyses highlight a role for tissue-specific expression of genes at chromosome 5q13.3, 12q13.2, 17q21.31, and 19q13.32 […]
