Researchers found that knocking out growth hormone receptors in fat tissue of aged male mice significantly improves brain health and cognitive performance. This study highlights adipose tissue's role in regulating brain aging, though its implications for humans remain uncertain due to the specific mouse model used.

Ghost lineages, ancient populations detected through DNA analysis sans fossils, reveal greater past genetic diversity than current species, especially in Arctic climates. Such findings challenge the linear narrative of human evolution, highlighting complex interbreeding among archaic groups like Denisovans, Neanderthals, and modern humans.

Vaccination remains the most effective method to prevent both immediate infections and long-term chronic illnesses. Despite this, public trust in vaccines is declining due to mixed messages and political influence, increasing health risks.

Ghost lineages, ancient populations identified solely through genetic analysis, reveal a braided human evolution with interbreeding among Denisovans, Neanderthals, and Homo sapiens. This discovery enhances our understanding of historical biodiversity, highlighting the complexity of human ancestry and the impact of past climate changes.

A groundbreaking study reveals that targeting memory-related neurons with a specific OSK cocktail can reverse cognitive decline in mice. This technique demonstrates potential for addressing age-related memory loss and Alzheimer’s effects by rejuvenating neurons without dedifferentiation.

Longevity Global is set to host its inaugural Longevity Innovation Forum in San Diego on March 11-12, 2026, uniting leaders in science, biotech, and investment to advance aging research. The event will feature prominent speakers and offer a platform for collaboration through keynotes, panels, and networking, aiming to bridge research with practical applications.

A new review highlights adiponectin's role in improving insulin sensitivity and reducing inflammation, potentially mitigating age-related decline. It explores genetic, mechanistic, and therapeutic aspects, emphasizing its complex, tissue-specific effects on aging.

A new pH-responsive polymer gel promises needle-free insulin delivery by penetrating the skin and normalizing blood glucose levels in animal tests. While it shows potential for replacing injections, extensive human trials are needed to ensure safety and efficacy.

A 10-year fishing ban in the Yangtze Basin, implemented in 2021, has led to significant ecological recovery, according to a new study. The ban reversed a seven-decade decline in aquatic biodiversity, but experts caution that resuming fishing could undo progress.

Consistent sleep of 7-8 hours nightly is crucial for health, reducing risks of heart disease, diabetes, and premature death, and enhancing brain function. Dr. Eric Verdin emphasizes that healthy sleep rivals diet and exercise in promoting longevity, debunking myths like naps or alcohol compensating for poor sleep.

New research highlights that younger microbiomes can rejuvenate aging intestines, enhancing healing and function. This discovery points to potential therapies for age-related intestinal issues.

A new polymer-based gel shows promise in delivering insulin through the skin without needles, effectively managing blood sugar in diabetic mice and pigs for up to 12 hours. While promising, experts emphasize the need for extensive safety studies and clinical trials before it can be used in humans, with potential future applications for other therapeutic proteins.

A new study reveals Earth's core may contain 0.07% to 0.36% hydrogen by weight, suggesting it as the planet's largest hydrogen reservoir. Researchers used advanced techniques to simulate core conditions, challenging prior theories on hydrogen's origin.

New research reveals hearing aid users have a 15% lower risk of cognitive impairment compared to non-users. This study, funded by NIH and other bodies, shows a 33% lower dementia risk among users.

Research reveals sleep deprivation reduces myelin cholesterol, impairing neural signals and cognitive function in rats. Cyclodextrin treatment restores cholesterol levels, improving performance and myelin structure.

A recent review reveals that guidelines for managing multimorbidity and polypharmacy in older adults often neglect patient preferences and monitoring strategies. Despite moderate implementability, there is a pressing need for guidelines to enhance methodological rigor and devise practical strategies for personalized, long-term care.

A long-term study indicates that speed-training with booster sessions can reduce dementia risk by 25%. However, experts warn that the findings, based on health records, need cautious interpretation.

A Swedish study links higher consumption of full-fat cheese and cream to a lower risk of dementia, particularly Alzheimer's, in adults without genetic risk factors. The research, however, stresses moderation and highlights that heart and brain health are interconnected through long-term dietary patterns, with no causation established.

Aging diminishes NK cell effectiveness due to impaired cytotoxic functions, impacting cancer and senescence response. Targeting Cdc42 with CASIN shows promise in restoring NK cell activity, but human trials are needed.
