Dementia prevention, intervention, and care: 2024 report of the Lancet standing Commission The 2024 update of the Lancet Commission on dementia provides new hopeful evidence about dementia prevention, intervention, and care. As people live longer, the number of people who live with…

~45% of dementia cases could be prevented or delayed by addressing 14 lifestyle factors

What factors?

Education, hearing loss, BP, smoking, obesity, depression, inactivity, diabetes, alcohol consumption, brain injury, pollution, isolation, LDL and vision loss

Reaching 50 without high blood pressure, high cholesterol, diabetes, smoking or abnormal BMI can add over 10 extra years free of cardiovascular disease

Each cigarette costs ~20 min of life, and lifelong smokers lose about 10 years. Quitting gives much of that back

People with strong social ties have 50% higher odds of survival. Being isolated can be as harmful as smoking up to 15 cigarettes/day. And no, your β€œsmoke break friend” does not cut it

Women who followed a Mediterranean diet for 25 years had 23% lower mortality, lower inflammation and better insulin sensitivity.

Five daily servings of fruit and veg was linked to a 13% lower risk of death vs 2 servings. Plants are still an underrated medicine

Irregular bedtimes raised the risk of major cardiovascular events by ~26%, even with similar total sleep. Go to bed at roughly the same time if you can. Your arteries notice

CRISPR-Cas9-induced double-strand breaks disrupt maintenance of epigenetic information - Genome Biology Background CRISPR-Cas9 genome editing enables precise genetic modifications by introducing targeted DNA double-strand breaks (DSBs). While Cas9-induced DSBs are known to cause unintended on-target mut...

New paper relevant to why we age:

1. CRISPR/Cas9-mediated DNA breaks cause methylation loss

2. This effect occurs genome-wide, not just the cut site

3. Natural DSBs show the same methylation disruption

These data strongly support The Information Theory of Aging link.springer.com/article/10.1...

Less than 7 hours of sleep is associated with ~14% higher mortality

Too much (8–9 hours) can raise it up to 34%

The sweet spot for most people is ~7–8 hours

Good news: you don’t need 12,000 steps. In 15 cohorts, the most active people had 40–53% lower mortality, with benefits plateauing at 6–10k steps

Frontiers | Inhibition of mesenchymal drift as a strategy for rejuvenation Mesenchymal drift (MD), the progressive acquisition of mesenchymal traits by epithelial and endothelial cells, has emerged as a unifying mechanism of aging. ...

New article: The Information Theory of Aging (ITOA) states that epigenetic drift is a cause of aging, with cells taking up new identities. New review says slowing a process called "mesenchymal drift" has emerged as a new strategy for rejuvenation www.frontiersin.org/journals/pha...

Jim Watson and me at his office at Cold spring Harbor

RIP James D. Watson, co-discoverer of DNAs double helixπŸ₯‡Jim was a kind, generous mentor to me, who never hesitated to meet, give feedback, or share stories from the early days of molecular biology. His signed double helix hangs in my office as a reminder how one discovery can change the world πŸ™
