Study links hypothalamic neuron cilia to caloric restriction and NAD+ effects in mice
Researchers report that many benefits of caloric restriction and increased NAD+ may depend on cilia of hypothalamic neurons. In mice, cilia length and NAD+ both declined with age in the hypothalamus, and NAD+ depletion or repletion changed cilia length in cultured neurons and in young mice.

Picard proposes energy resistance principle linking mitochondrial dysfunction to chronic disease and aging
Martin Picard and Nirosha Murugan codified an energy resistance principle in Cell Metabolism in November 2025, proposing that chronic diseases may share a root in cells struggling to extract and use energy from food. Picard argues that living at optimal energy resistance is the secret to longevity.

Lifespan.io op-ed says aging therapies need new regulatory pathways for multi-disease use
The article argues that biomedical repair therapies targeting aging hallmarks are held back by regulatory frameworks built for single-disease drugs. It says regulators, including the FDA, have been cautious about accepting aging biomarkers as clinical endpoints.

Laura Minquini discusses founding AthenaDAO and AthenaBio to fund female reproductive aging research
Laura Minquini, a non-scientist, describes how she moved from consumer tech into longevity after volunteering at retirement homes. She founded AthenaDAO to fund translational research in women's health and is now launching AthenaBio, a 501(c)(3) nonprofit focused on directing more capital to female…

How aging cell stress may help ovarian cancer grow and resist treatment
This paper proposes an idea, called a geroncogenic shift, linking aging, cell stress, and ovarian cancer. It is a concept piece, not a set of new experiments, so it does not prove the link.
Original title: Cellular senescence in ovarian cancer: a proposed geroncogenic shift linking aging, plasticity, and therapy resistance.
Light mask and cream study on skin aging in women
Skin samples and 50 women used a light mask and cream for weeks, and skin looked better. This study was small and early, so it does not prove the products work for everyone.

Aging cells may play a role in knee osteoarthritis, but the evidence is still early
This review looks at how aging cells may affect joint damage in osteoarthritis. It does not show that these cells cause the disease or that treatments aimed at them work in people.

A new 40-minute test may spot memory decline in dogs years before dementia signs
Researchers built a short test that catches subtle memory and impulse problems in dogs aged 7 to 8. It does not show what causes the decline or how to prevent it.

Senolytic drug reduced skin scarring after radiation in mice
Researchers studied how radiation causes skin to stiffen and scar. They found a loop between aging cells and immune cells that seems to drive it. The drug ABT-263 reduced scarring in these mice, but this does not show it works in people.
Original title: A senescence-driven fibroblast-macrophage feed-forward circuit promotes radiation induced cutaneous fibrosis.
Blood cells turned into brain stem cells slowly lose signs of age
Blood cells from people of many ages were changed into brain stem cells in a lab. The changes in age markers kept going for weeks, so this shows a slow process.

Short daily home workouts helped older adults with walking trouble move better
In this trial, people who did a 4-minute daily workout for 12 weeks did better on balance and leg tests. The results do not show how well these gains last or apply to everyone.

Research on aging cells and heart failure has grown fast since 2020
This study counted and grouped 479 published papers on aging cells in heart failure. It shows where the research is going, but it does not show whether any treatment works.

Experts pick signs that show whether frail older people can live well at home
Eighteen experts rated many possible signs of living well at home. Only four were rated both important and easy to measure, so more work is needed.

Cell study finds death receptors shape which aging cells survive chemotherapy
Scientists found that certain death signals help control which damaged cells become senescent. The work does not show whether this would help people or patients.
Original title: Death receptors regulate entry to therapy-induced senescence and orchestrate addiction to IAPs.
Healthy diets linked to slower epigenetic aging in two large groups
Researchers compared ten healthy diet scores and how they relate to DNA aging markers. Eating a healthy pattern was linked to less epigenetic aging, but the size of the link varied by score.

LSD extended lifespan in tiny worms in a lab study
Researchers gave LSD to microscopic worms and found they lived longer, by up to 17.6 percent. This is a worm study, so it does not show LSD would extend human life.

Apelin-13 protected brain cells from aging in cells and mice
Researchers found that apelin-13 helped brain cells resist aging signs by restoring their cleanup process. This work was done in cells and mice, so it does not show the same effect in people.

Mailed stool test kits did not clearly raise colon cancer screening after 3 years
Mailing stool test kits to patients at community clinics raised screening at 2 years, but not at 3 years. The difference at 3 years was not statistically significant, so the effect over time is unclear.
