Five epigenetic clocks reveal shared and distinct signals of aging

Researchers linked five epigenetic clocks to distinct blood gene-expression patterns and biological pathways in 3,227 Health and Retirement Study participants. TAGS derived from these patterns often showed stronger associations with frailty, functional measures, morbidity, and mortality than their parent clocks, although further validation is needed.

Low-dose lithium may protect brain networks in early Alzheimer’s disease

This perspective examines whether restoring physiological lithium levels could help protect cognition in early Alzheimer’s disease. It proposes that lithium may support cholinergic signaling and brain connectivity, but emphasizes that rigorous, safety-monitored clinical trials are needed.

Spring clock change increases retinal vascular disease risk, study finds

For the first time, Northwestern Medicine scientists have detailed how the semiannual clock changes impact a person's risk of developing retinal vascular disease, a group of disorders that affect blood vessels in the retina and can lead to vision loss.

Beetroot juice shows its clearest aerobic benefits in recreational exercisers

A meta-analysis of 38 placebo-controlled trials involving 703 participants found that beetroot juice supplementation was associated with a small improvement in VO2max or VO2peak during aerobic exercise. Benefits were most consistent in recreationally active adults, while evidence in highly trained athletes remained limited and uncertain.

Micro and nanoplastics in the blood linked to increased heart attack risk factors

People who have suffered a serious heart attack had higher levels of micro and nanoplastics in their blood, compared to patients diagnosed with chronic ischemic heart disease and those who have normal blood vessels supplying the heart, according to a study published in the European Heart Journal today (Wednesday).

New Italian data show extreme longevity is spreading beyond the blue zones

A nationwide ecological analysis of Italian regions found that aging and extreme longevity indicators rose steadily from 1982 to 2025, with northern and central regions generally leading. Regional patterns linked higher longevity indices to lower diabetes and cerebrovascular mortality and healthier contemporary nutrition profiles, while Cilento emerged as a notable southern hotspot.

Sleep apnea and erectile dysfunction share a stronger link than expected

A systematic review and meta-analysis of 8 observational studies found that greater obstructive sleep apnea severity was associated with poorer erectile function, with higher AHI linked to lower IIEF scores and higher minimum oxygen saturation linked to higher IIEF scores. The authors caution that the evidence remains observational, heterogeneous, and low certainty, so the findings support targeted screening rather than proving causality.
