THIS WEEK IN LONGEVITY
š§Ŗ Blood filter may help clear microplastics from the body

Source: Midjourney | longer.
Researchers have found signs that a common blood-cleansing procedure might also pull out tiny plastic particles. Itās early evidence, but it opens the door to a future where detoxing means more than green juice and good intentions.
What to know:
The procedure is already in use: Therapeutic apheresis is a filtering technique where blood is drawn out, passed through a machine to remove certain components, then returned to the body.
Microplastics found in patientsā blood: In a study of 21 people with post-viral fatigue, researchers detected microplastic-like particles in the filtered waste ā but not in the clean equipment or fluids.
What was found: Particles matched industrial plastics like nylon and polyurethane, including some smaller than 200 nanometers (thatās smaller than a virus).
Testing tool isnāt perfect: The method (ATR-FT-IR spectroscopy) identifies chemical āfingerprints,ā but canāt precisely quantify plastics ā and might also pick up proteins.
More proof needed: This is a small, early-stage study. Larger trials will need to confirm that apheresis reliably removes microplastics and whether that actually improves health.
Why itās important: Microplastics are in our water, food, and now ā our blood. If theyāre quietly undermining our health, weāll need ways to get them out, not just avoid them. Think of this like a HEPA filter for your bloodstream ā still in beta.

š Metformin linked to longer life

Source: Midjourney | longer.
Women who took metformin ā a common diabetes drug ā were more likely to live past 90 than those on another medication. Itās not quite a fountain of youth, but it might be the most interesting thing in your medicine cabinet.
What to know:
Studied in real-world data: Researchers used long-term data from the Womenās Health Initiative (WHI), which has tracked over 160,000 women for more than 30 years.
Metformin vs sulfonylurea: Those taking metformin had a 30% lower risk of dying before age 90 compared to women taking sulfonylureas (an older type of diabetes drug).
Not compared to placebo: Since it wasnāt tested against no treatment, researchers canāt yet confirm whether metformin itself causes the longevity boost.
Why itās promising: Metformin targets several aging-related processes ā including inflammation, mitochondrial function (your cellsā energy engines), and insulin signaling.
A bigger trend: Metformin is part of a growing class called gerotherapeutics ā drugs being explored for their potential to slow aging.
Why itās important: If a widely used, low-cost drug can help extend lifespan, it could reshape how we think about aging ā not just treating disease, but delaying it. Aging quietly starts in your 30s; maybe prevention should too.

IN THE SPOTLIGHT

1. Slowing muscle aging with enzyme tweak
Turning down HDAC11, an enzyme that slows fat burning in muscle cells, preserved strength, stem cells, and repair in aging mice. Drugs that block it already exist. The shift improved mitochondrial function, lowered harmful fats, and helped muscles resist age-related decline. More energy, better recovery, and less frailty could be within reach.
2. Stem cell signals show anti-aging effects
Stem cells and tiny bubbles they release, called vesicles, improved brain and organ health and extended lifespan in aging animals. Human results are still unclear. These treatments lower inflammation and may slow aging, but we canāt yet measure how well they work. Big hopes, but the dataās still catching up.
3. Cosmetics meet science to slow skin aging
Researchers propose ālongevity cosmeceuticalsāāproducts that go beyond looks to target real biological aging in the skin. They must meet strict scientific standards. These actives aim to boost skin health by hitting aging at the cellular level, not just masking wrinkles. Think of it as skincare with a lab coat on.
THE NEXT BIG THING
Longevity Goes Vertical

An abandoned office tower in San Francisco is now a living lab for aging research.
The 16-story Frontier Tower is hosting 350 scientists, founders, and biohackers for a six-week experiment in fast-tracking clinical ideasāfrom daily workouts and shared meals to rooftop debates and roundtable trials.
Launched by Viva.city and Berlinhouse, this pop-up city aims to prove a bigger concept: that reimagined real estate can speed up the science of aging.
More than a vibe shiftāitās a prototype for what comes next.
WHAT ELSE YOU SHOULD KNOW THIS WEEK

Source: Naturhotel Forsthofgut
š§ Upgrade Aging: A new Nature Aging paper proposes replacing aging body partsācells, organs, even brain circuitsābefore they fail. The bold plan treats aging as modular wear, not an unsolvable mystery.
šŖ Muscle Boost: Juvena starts its first human trial of JUV-161, a protein therapy that reverses muscle loss by restoring youthful growth signals. It targets myotonic dystrophy first, with wider aging applications next.
š§“ Skin System: SYSTEM SKIN, a Madrid-born brand, uses deep-tech and systems biology to treat skin as a whole aging network, not just surface flaws. Its OmniverseĀ® tech optimizes skin from DNA to muscle.
āļø Forest Reboot: Naturhotel Forsthofgutās new WaldSpa Health in Austria offers cryotherapy, oxygen treatments, and AI-guided diagnostics. The goal: long-term vitality through nature and science.
āļø Winter Shield: A 10-week indoor workout cut winter vitamin D loss by 40% in a UK studyāno sun or supplements needed. Exercise kept immunity-boosting vitamin D at healthy, active levels.
