A new study demonstrates that novel gene-editing tools can correct disease-causing mutations in mitochondrial DNA in primary human cells [1]. Smaller editing tools needed Genome-editing tools such as CRISPR were one of the greatest scientific breakthroughs of this century. However, they are only good for editing nuclear DNA. Mitochondria, the energy-producing organelles, have their own...

Researchers have found that inflamed, senescent microglia prune too many synapses in the hippocampus and demonstrated that a senolytic compound can ameliorate this process in Aging Cell. Some synapse pruning is normal During brain development, the resident immune cells of the brain (microglia) prune unneeded synapses as a form of maintenance. This is normally a...

In this Lifespan interview, we speak with Gabriel Cian, founder of the 2060 Longevity Forum, about how his background in software shaped his views on healthspan innovation, the forum’s approach to scientific and investment credibility, and what he sees as the biggest bottlenecks and opportunities facing the field of longevity today. Hi, Gabriel. Let’s start...

Researchers have analyzed molecular patterns from different tissues obtained from over 700 people and learned that smoking acts as an aging accelerator and involves molecular changes in tissues beyond those directly exposed to cigarette smoke [1]. Millions of preventable deaths Despite campaigns aimed at the reduction of tobacco smoking, it is still a very common...

By comparing data from industrialized and non-industrialized societies, a new study calls into question some assumptions about the relationship between inflammation and aging [1]. Harmful protection Inflammation accompanies us throughout our entire lives. Without it, we would not be able to fight off pathogens. Yet, inflammation also harms tissues and organs and, as such, is...

In Cell Stem Cell, a trio of reviewers has proposed five hallmarks that are specific to the aging of stem cells. Functional rather than molecular This review begins with a note that its classifications focus on the physical features and overall behavior rather than what is going on biochemically. This is because the hallmarks of...
