A new Nature Aging study found a fat-related chemical signal that marks aging cells in mice without destroying the tissue. The tool is promising for research, but scanning one square millimeter currently needs about 30 hours and has not been tried in people.
A Harvard preprint posted in September found old donor hearts looked younger in young recipients, and young hearts looked older in old ones. It could widen the donor pool, but the human evidence is thin and has not been peer reviewed.
The CHOICE trial, published September 28, is the first large randomized test of hearing aids in people who already have mild memory decline. Dementia rates were similar in both groups, while far more hearing aid users saw their memory scores return to normal.
A new analysis of 3.8 million blood immune cells from 1,828 healthy people finds immune aging is not a smooth slope. Separate immune aging clocks for men and women also beat a single shared clock.
A Nature Aging study published September 29 links the loss of cardiolipin to the odd way muscles change as we age. The team also traced the molecular switch behind one of aging muscle's strangest changes.

Five weeks after launch, the Ackman Oxman Institute helped lead a $250 million round for Precision Neuroscience. The mitochondria treatment that inspired it remains a single patient whose benefit faded within weeks.
A Science Advances study out September 17 traces part of the age-related drop in NAD, the molecule behind a booming supplement market, to an enzyme inside blood vessel walls. The mice were engineered to age fast, which limits what it means for you.
*A new study in Aging Cell cut growth hormone signaling in mice at the human equivalent of about age 40. Females gained 8% in median lifespan, and males maintained more strength, but the gains were smaller than in lifelong models.
A Nature Medicine paper out September 22 finds the change tracks hormones more than birthdays. The link to dementia is real but modest, and there is nothing to test for yet.
A Finnish study that followed 2,690 men until nearly all of them had died, published in late August, answers the question every healthy-habits lecture skips: do the extra years feel good?

Two studies published September 22, and an advisory vote on September 23, give the clearest picture yet of what one blood draw can and cannot tell you about cancer.
It is the first time a pig organ has carried a patient all the way to a human transplant, and formal trials for people in their 50s and 60s are now starting
When the mutations were confined to heart muscle cells, pumping strength fell by about 25 percent by 9 months and kept sliding with age.
A Nature study traced the inflammation to a mitochondrial citrate pump, and blocking it for three months delayed frailty without killing a single cell.
A 7,504-person German study found that these diets barely overlapped on the plate yet pointed to the same biological pathways.

The heart benefit is real. The independent-years benefit is not
A 154,000-person study links accelerated aging to early-onset cancer in adults under 55.
The first lifespan study of a GLP-1 drug matched calorie restriction and beat it on memory and glucose
A Yale-led analysis of the only long-term calorie-restriction trial in humans identifies the switch that quiets inflammaging
The two-year LatAm-FINGERS trial delivered a 55 percent bigger cognitive gain than flexible guidance.
