Scientists discover how macrophages age differently throughout the body

Why does the immune system become less effective as we age? A new USC study published in BMC Biology offers fresh insights by examining a key immune cell type across tissues: macrophages.

Macrophages act as the body’s cleanup and maintenance crew. Found in nearly every tissue, they help fight infections, remove damaged cells, repair tissues and keep inflammation under control, acting as a first line of defense for the immune system. But like many cells in the body, macrophages change as we get older.

In this new study, researchers analyzed data from macrophages collected from different mouse tissues, including the brain, lungs, liver and other organs. By comparing younger and older animals, they uncovered common patterns of aging shared across many macrophage populations, as well as important differences depending on where the cells come from.

Harvard University hosts the world’s largest conference dedicated to longevity biotechnology

The 13th Aging Research & Drug Discovery (ARDD) Meeting, the world’s largest conference dedicated to longevity biotechnology, will take place from October 1–3, 2026, at the David Rubenstein Treehouse at Harvard University. Marking the high-profile launch of Boston Longevity Week, this landmark event is officially organized by Insilico Medicine, which also anchors the conference as a Tier 1 sponsor alongside Eli Lilly.

As longevity science rapidly transitions from theoretical concepts to multi-billion-dollar therapeutic pipelines, ARDD 2026 stands as the premier global nexus connecting basic science, clinical research, big pharma, and institutional investors. Moving the conference to Boston-the global epicenter of biomedical innovation-reflects the field’s evolution into mainstream medicine.

Building on the massive momentum of previous years-including ARDD 2025 in Copenhagen, where leadership from Eli Lilly and Novo Nordisk discussed the profound longevity potential of GLP-1 receptor agonists in Nature Biotechnology-the 2026 conference solidifies aging research as a core pillar of healthcare. Top-tier pharmaceutical companies are now actively developing commercial programs targeting fibrosis, immunology, CNS, cardiometabolic diseases, anti-muscle wasting, and cellular rejuvenation.

Dr. David Sinclair: The First Human Trial of an Age-Reversal Therapy #podcast #lifespan #longevity

Harvard geneticist David Sinclair returns to explain how his lab’s age-reversal technology has moved from mice and primates into FDA-cleared human trials — starting with an attempt to reverse vision loss from glaucoma, a condition considered permanent. Sinclair breaks down the science of Yamanaka factors, why using three genes instead of four sidesteps the cancer risk, and his core thesis: make the body young enough and it can cure its own diseases.

He and James also go deep on the practical longevity playbook: NMN, NAD and Sirtuins, metformin and berberine, testosterone and muscle mass, sleep, diet, and how to separate real science from longevity misinformation. Sinclair shares his own protocol at 56, his 86-year-old father’s results, and teases a next-generation \.

Combining Senolytics and Stem Cells Shows Promise in Mice

A new study associated with Immorta Bio suggests that combining a senolytic vaccine with mesenchymal stem cells might create a synergistic impact. However, the findings rest on acute, artificially induced injury models rather than natural aging [1].

Clearing out senescent cells to help stem cells work

Mesenchymal stem cell (MSC) therapies have largely underperformed in the clinic. MSCs are connective-tissue stem cells that help mostly not by becoming new tissue but by secreting repair-promoting factors. Despite strong preclinical promise, clinical MSC trials in fibrosis, inflammation, and organ failure have shown only modest benefits [2].

Uploading the Human Mind To AI Is Now REAL | Artificial Immortality | Full Documentary

If you were able to create an immortal version of yourself, would you? Until this decade, that question was the stuff of science fiction, but now experts in the fields of artificial intelligence and robotics suggest it will indeed be possible. This cinematic documentary explores the latest technological advancements in AI, robotics and biotech, and poses the question: what is the essence of the human mind, and can this be replicated? Or even more unsettling, could we one day meet cloned versions of ourselves – clones which are better, smarter, and immortal?

LONGEVITY EXPERTS: How Close Are We to Solving Death?

Interesting but no mention of Dr. Fahy.

What’s the biggest problem in longevity today: bad science, hype, or misplaced optimism?

This episode is brought to you by NADclinic.com, the go-to destination for longevity and human performance. Check out their new NADair, a next-gen, precision breath-activated NAD⁺ wellness system using multi-patented DPI technology: https://nadairx.com/

This debate brings together leading voices in longevity to separate evidence from speculation. They discuss why misinformation is growing and why many people chase advanced treatments before addressing basic health.

The panel explores longevity escape velocity, healthspan versus lifespan, and how much progress has actually been made. They debate whether dramatic life extension is near or still much farther away than many believe.

UCSF and Samsung launch remote study on aging brain health

An innovative new study from the Neuroscape research center at UCSF, and consumer electronics giant Samsung seeks to understand decade-by-decade changes in brain health.

The Neuroscape Technology for Aging Health — Digital Approaches (TAH-DA) longitudinal study, seeks to identify biometric predictors of cognitive decline over the course of a year, using Samsung wearable technology.

Samsung fosters innovation and transformational health research in collaboration with leading institutions to explore new health technologies and a novel prescriptive on wellness. The TAH-DA study is another example of Samsung’s work to understand the unique connection between the brain and wellness.
