670nm red light exposure improved aged mitochondrial function, colour vision (nature.com)
Mitochondrial decline in ageing robs cells of ATP. However, animal studies show that long wavelength exposure (650–900 nm) over weeks partially restores ATP and improves function.

Facing the Music or Burying Our Heads in the Sand? (nlm.nih.gov)
Defenses that keep threatening information out of awareness are posited to reduce anxiety at the cost of longer-term dysfunction. By contrast, socioemotional selectivity theory suggests that preference for positively-valenced information is a late-life manifestation of adaptive emotion regulation.

Muscle-Brain Crosstalk: How Skeletal Muscle Influences Neurocognitive Function (gethealthspan.com)
The term 'sarcopenia' might evoke images of weakening muscles and reduced physicality in the elderly. But this decline in muscle mass and strength, prevalent among older adults, has ramifications far beyond just physical fragility.

Micro nutrients as immunomodulators in the ageing population (biomedcentral.com)
Immunosenescence, the slow degradation of immune function over time that is a hallmark and driver of aging, makes older people much more likely to be killed by common infections (such as flu) than young adults, but it also contributes greatly to rates of chronic inflammation in later life.

Is It Possible to Improve Memory or Are We Doomed to Forget as We Age? (2023) (nzherald.co.nz)
Memory is a fickle beast at the best of times, but it’s easy to think we’re sliding into a pandemic of forgetfulness, a collective midlife side-effect of living a life so fast-paced, we can’t possibly be expected to remember where we put the keys.

The risk of cancer fades past the age of 80 (sciencealert.com)
Aging brings two opposing trends in cancer risk: first, the risk climbs in our 60s and 70s, as decades of genetic mutations build up in our bodies. But then, past the age of around 80, the risk drops again – and a new study may explain a key reason why.
