ACOG's First Menopause Guideline Since 2014 Strongly Backs Hormone Therapy
For the first time since 2014, the American College of Obstetricians and Gynecologists (ACOG) has updated its guidance on treating menopause symptoms, and it says the safety of hormone therapy is now "well-established."
Brain health →Nicotinamide Riboside Fails to Slow Early Parkinson's in 410-Patient Trial
A popular NAD+ supplement did not help people with early Parkinson's disease in a large, well-controlled trial, and those who took it did slightly worse than those given a placebo.
Reading medical evidence →Eight-Hour Eating Window Plus Exercise Did Not Cut Liver Fat More Than Usual Care
Eating all your meals inside eight hours, with supervised exercise on top, did not shrink liver fat any more than simple diet and activity education did over 12 weeks.
Strength and function →Study of 247,000 Adults Finds Which Dementia Risk Factor Clusters Matter Most
Dementia risk factors rarely travel alone, and a large Dutch study suggests that the combination may matter: in adults over 65, a cluster of loneliness, depression and physical inactivity was linked to the highest rate of dementia.
Brain health →In Hospital, Standard Exercise Beat Virtual Reality Exercise for Physical Function in Over-75s
A hospital stay can leave an older person weaker than when they arrived, and a new trial asked whether exercise on the ward, with or without virtual reality, can change that.
Strength and function →FDA Clears AI Tool That Estimates Early Breast Cancer Recurrence Risk From MRI Scans
A breast MRI that many women already have may now be turned into a score for how likely early breast cancer is to come back. The FDA has cleared the software that does it. Whether that score should change anyone's treatment is still unanswered.
Care and connection →Atlas of 375,000 Human Blood Vessel Cells Maps How the Vessel Lining Ages
Every blood vessel in the body is lined with a single layer of cells, and a new atlas of more than 375,000 of them shows how that lining changes across adult life.
Longevity in daily life →Youth-Linked Protein TIMP2 Restored Some Immune Cell Function in Aged Mouse Brains
A protein that is abundant in young blood and fades with age appears to help keep the brain's immune cells working properly, at least in mice.
Brain health →Gene Editing Moved Lab-Grown Progeria Blood Vessels Back Toward Healthy Levels
Researchers at Duke University have built a three-layer human artery in the lab, given it the gene fault behind a premature-aging disease, and then corrected that fault with a gene editor. Several signs of vessel damage moved back toward healthy levels.
Strength and function →Psilocybin Reshaped Brain Connections in Mice, Separately From Hallucination-Like Behavior
Long-term stress may leave a physical mark on the brain: fewer working connections between nerve cells. A new study in mice asks whether psilocybin, the compound in "magic mushrooms," can reshape those connections, and which part of its action does the work.
Brain health →Cyclic Yamanaka Factor Reprogramming Reduced Stroke Damage in Aged Mice
Age is the biggest risk factor for stroke, and older people tend to recover worse. A new mouse study asks whether turning back the clock inside brain cells could help the aging brain withstand one.
Brain health →Sustained GLP-1 Use Linked to Lower Diabetes Incidence in Over-65s
Older adults with obesity who kept filling prescriptions for a GLP-1 drug were less likely to be diagnosed with diabetes than those who filled only one or two, according to a large study of health records from Israel.
GLP-1 medicines →Bone Loading Late in Life Extended Mouse Lifespan About 9%
Mice that had their shin bones gently loaded in old age lived 9.4% longer, or 79.5 days, according to a new study in Cell Metabolism.
Longevity in daily life →Oral Alzheimer's Drug Targeting Brain Immune Cells Passes Early Safety Trial
A pill that reaches the fluid around the brain and acts on the brain's own immune cells has passed its first safety test in people. It has not yet been tested to see whether it helps memory or thinking.
Brain health →Neurons Made From Older Donors' Cells Struggle to Clear Damaged Mitochondria
Neurons need a steady supply of working mitochondria, the parts of a cell that make energy, and a way to remove them when they are damaged. A new laboratory study suggests that in neurons made from older people's cells, the removal process stalls before it finishes.
Brain health →FDA Clears AI Software Gauging Heart Artery Blockages From CT Scans
The US Food and Drug Administration has cleared software that uses artificial intelligence to estimate whether a narrowed heart artery is actually limiting blood flow, working from a standard CT scan rather than a wire placed inside the heart.
Longevity in daily life →Weaker Artery Dilation Tracks With Higher Predicted Heart Risk in Diabetes
Nearly four in five people with type 2 diabetes in a large Chinese hospital group had arteries that did not widen as well as they should, and the weaker the response, the higher their calculated heart risk tended to be.
Care and connection →Causal Gene Network Made 55-Year-Old Cells Resemble 25-Year-Old Cells
Skin cells from 55-year-old donors, grown in a dish, have been shifted toward the profile of cells from 25-year-olds. That is the claim of a new preprint on bioRxiv. It rests on a way of separating genes that merely change with age from genes that may drive those changes.
Longevity in daily life →Chronic NAD Shortage Caused Frailty and Early Death in Mice; Niacin Reversed It
Mice kept short of a key cell molecule called NAD developed a curved spine, cataracts, frailty and shorter lives, and restoring dietary niacin reversed those changes, according to a new study in Nature Communications. The mice were a special model, and the paper itself says they should not be viewed as an aging model.
Reading medical evidence →CHEST 2026 Abstracts Link GLP-1 Drugs to Better Sleep Apnea Outcomes
People with obesity and obstructive sleep apnea who take GLP-1 drugs may face a lower risk of a serious breathing emergency, according to Managed Healthcare Executive's report on research set for the CHEST 2026 meeting in Phoenix.
Sleep →FDA Agrees Phase 3 Design for Zervimesine in Lewy Body Dementia
Families living with dementia with Lewy bodies have no approved drug that slows the disease. According to Longevity.Technology's report, a company now has a plan for a pivotal trial, with key design elements agreed with the regulator, that could test one.
Brain health →Elastic Band Training Improved Strength and Gait in Older Women at Risk of Sarcopenia, Small Trial Finds
After 12 weeks of resistance training with elastic bands, older women at risk of age-related muscle loss walked with longer strides and spent less time with both feet on the ground.
Strength and function →XPRIZE Awards $1 Million to Team Testing Elamipretide in Older Adults
A drug that targets the energy-making parts of cells has won $1 million in a major longevity competition. Whether it helps older people stay stronger, sharper or more resilient is still unknown.
Reading medical evidence →Mandatory Ultra-Processed Food Labels Could Cost $14.2 Billion Yearly, Analysis Estimates
A federal ultra-processed food label could land on nearly three of every four packaged products in the US, including some sold as healthy, according to a new analysis tied to the University of Chicago. The same analysis puts the yearly cost of such a policy at $14.2 billion or more.
Longevity in daily life →INmune Bio Tests Quantum Computing and AI to Find New Uses for Alzheimer's Drug
A biotech company wants a quantum computer to tell it what else its Alzheimer's drug might treat. So far, nothing has been found. What exists is a plan, and a plan that includes a test of whether the quantum part helps at all.
Brain health →Samsung Smartwatch Detected Moderate-to-Severe Sleep Apnea With 94% Sensitivity
A smartwatch picked up about 94 in every 100 people with moderateto-severe sleep apnea in a new study. At its default setting, it also flagged about one in three people who did not have the condition.
Sleep →How the APOE4 Alzheimer's Gene Disrupts Brain Insulation, and a Possible Fix
The APOE4 gene variant is the strongest genetic risk factor for lateonset Alzheimer's disease, yet how it raises risk has stayed unclear. A new study points to one pathway: fat build-up in the brain cells that make the insulation around nerve fibres, and an enzyme that might be switched down to reverse it.
Brain health →AthenaBio Founder Laura Minquini on Funding Research Into Ovarian Aging
Women tend to live longer than men, but one founder in the field argues that many of those extra years come with poorer health, and that longevity science has not done enough to explain why.

Genesis HealthCare Liquidation Plan Caps Resident Injury Claims Near 26%
A federal judge has approved the Chapter 11 liquidation of Genesis HealthCare, and families with injury and wrongful death claims against the nursing home giant will likely recover only about a quarter of what they are owed.
Care and connection →California Nursing Homes Cluster Below 100 Beds, Study Says, Dodging Staffing Rule
A staffing rule meant to raise care standards may be doing something else: pushing weaker-staffed nursing homes to stay just under the size where the rule applies. That is the central claim of a new economics paper on California facilities.

Borrowing costs for senior living deals have jumped this year, yet the people who broker and finance those deals say activity is still running at or near last year's record pace.
Longevity in daily life →FDA Approves First Generic of Weekly Combination Menopause Hormone Patch
Bayer's once-weekly Climara Pro menopause patch now has its first generic rival, and the key question for the market is whether lower prices follow.
Longevity in daily life →SOA Data Show US Mortality Improving Across All Age Groups
US death rates kept falling in the second quarter of 2026, and no age group bucked the trend. That is the central finding of the latest Society of Actuaries quarterly mortality report, and it bears on how life insurers, annuity writers and pension risk transfer (PRT) providers think about future claims and payouts.

Will IL-11 Drugs Slow Aging Only in People With Scarred Organs? A Testable Idea, Rated 25 Percent
Our research desk proposes that blocking the cytokine IL-11 will move aging markers in older people with fibrosis, not in healthy volunteers. The mouse data are real, but one key premise does not match the paper.
Reading medical evidence →Brain-Age Scans May Mostly Measure Blood Vessel Health, Not Neurons. Our Desk Rates It 67 Percent
MRI brain age is becoming a trial endpoint. Our research desk proposes that after 60 it mainly tracks small-vessel health, which would change how drugs are judged. The evidence so far is mixed.
Brain health →Does Diluting Old Blood Work Like Raising Ore Grade? A Mining Analogy for Plasma Exchange, Rated 45 Percent
Our research desk proposes that plasma dilution helps old tissue by improving the overall signal quality of blood, not by removing one bad molecule. It predicts benefit peaks at 50 percent dilution. Human trials so far point in both directions.
Reading medical evidence →Could Gut Bacteria Steal the Spermidine Your Gut Lining Needs?
Our research desk proposes that spermidine-hungry gut bacteria could starve intestinal cells of a molecule tied to autophagy. This is a long-shot hypothesis. Most links in the chain have support, but the premise that these bacteria rise with age is unsourced here and the full chain is untested. The desk gives it only a 30% chance, and it is no reason to buy supplements.

Could Embryos Be Blind to Some Rhythms? A Sampling Idea for the Spine
Our research desk proposes that the embryo's segmentation clock samples incoming signals the way a digital recorder does, so some rhythms should leave no trace and others should look identical. The sampling math is textbook. The biology is untested, and the proposed pulse timings assume a zebrafish clock, while the published pulsing method was built for mouse tissue.
