A new study suggests betaine, a natural compound found in foods like beets, leafy greens, and whole grains, could mimic some benefits of exercise. Researchers say betaine may help reduce chronic inflammation and slow tissue ageing, offering a complementary approach to healthy ageing. The study notes that exercise naturally raises body betaine levels, while supplements might replicate some exercise benefits. This could be meaningful for people who cannot engage in regular physical activity due to mobility or health constraints.

In a landmark study that could reshape approaches to healthy ageing, researchers have identified a natural supplement, betaine, that mimics the benefits of exercise—including reduced inflammation and slowed tissue ageing. This finding, recently published in the scientific journal Cell and widely reported in international media, has the potential to revolutionize the fight against age-related diseases and extend human healthspan, particularly for those unable to maintain regular physical activity (gbnews.com, medicalxpress.com, pubmed.ncbi.nlm.nih.gov, nmn.com).

A collaborative team from the Chinese Academy of Sciences and Capital Medical University in Beijing conducted an in-depth analysis revealing that betaine, a compound found naturally in foods such as beetroot, spinach, and whole grains, interacts with key molecular pathways involved in inflammation and cellular ageing. Crucially, regular exercise was found to increase levels of betaine in the body—but new evidence now shows that taking betaine as a supplement can trigger similar anti-ageing effects, offering hope to those unable to exercise regularly due to physical limitations or chronic illness.

The struggle to access contraception in the United States has become more difficult in recent years, prompting advocates in New York to devise novel solutions such as vending machines dispensing Plan B pills and other over-the-counter products on university campuses. As the national landscape of reproductive rights continues to shift—especially in the wake of clinic closures and new legal hurdles—New York’s approach offers fresh hope and urgent lessons for other regions, including Thailand, where access to reproductive healthcare is an ongoing concern.

A groundbreaking new study highlights that not just the amount, but the timing and regularity of physical activity are decisive in maintaining and improving VO2 max—a key measure of cardiovascular fitness—among older adults. This research, which analyzed nearly 800 people aged 70-plus, suggests that consistent activity, particularly in the morning, can have profound effects on healthy aging and longevity—a message with growing relevance for Thailand’s rapidly aging society (Runner’s World).

A wave of headlines has cheered that exercise is “better than drugs” for preventing colon cancer recurrence, suggesting an exciting shift in how survivors might chart their recovery. But a closer examination of the latest landmark research, published in the New England Journal of Medicine in June 2025, brings a far more nuanced—and ultimately more practical—message for cancer patients and the health community, including here in Thailand. The real story isn’t a competition between medicine and movement, but a call for a more holistic approach in which structured exercise and medical care both play distinctive and powerful roles in ensuring long-term health and survival.

A rise in self-directed supplementation has sparked fresh concerns about vitamin B6 toxicity. New research and regulatory scrutiny suggest that excess intake may cause nerve damage at lower doses and shorter exposures than previously understood. Australia’s Therapeutic Goods Administration signals it may have underestimated adverse effects, prompting tighter scrutiny of high-dose B6 products. This reflects a growing global move toward cautious use of over-the-counter vitamins.

Vitamin B6, or pyridoxine, supports metabolism, brain function, immune health, and red blood cell formation. It is common in multivitamins and is often taken during pregnancy or to ease premenstrual symptoms. For most adults, daily needs are roughly 1.3 to 1.7 mg. In Thailand, typical diets provide ample B6 from meat, grains, fruits, and vegetables, reducing the perceived need for extra supplementation.

A recent advice-column discussion has Thai readers wondering if adult penis size can shrink with age or simply seem smaller. The question stems from a past sexual encounter where one partner appeared smaller than before, raising questions about real changes, contributing factors, and how memory shapes perception. Current medical understanding offers a clearer, nuanced view relevant to Thai audiences and readers worldwide.

Misconceptions about size and aging persist. Medical science shows that aging alone does not reliably shorten penile length or girth. Many studies find little or no consistent reduction across ages. Perceived changes often come from factors like increased fat around the pubic area, which can mask visible length. Thailand’s health data align with the view that aging by itself is not a primary cause of size reduction.

A new study shows that when and how regularly people move influences VO2 max, the body’s ability to use oxygen during activity. Among about 800 participants aged 70 and above, those with steady routines—especially morning activity—displayed higher VO2 max. The findings, highlighted by the National Institute on Aging, arrive as Thailand’s population ages and guidance for seniors becomes increasingly important.

VO2 max is the gold standard for cardiorespiratory fitness. It measures how efficiently the body takes in and uses oxygen during exertion. A higher VO2 max is linked with better endurance, a lower risk of chronic disease, improved mobility, and potentially longer life. For Thai readers, maintaining VO2 max supports independence and resilience against age-related health challenges.

A ground-breaking study led by researchers at the University of Rochester has pinpointed a possible biological reason behind the well-documented trend: boys are diagnosed with autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) three times more often than girls. The focus of the research is on the impact of a common contaminant known as PFHxA, a “forever chemical” used in products ranging from food packaging to stain-resistant fabrics, which has now been shown to cause anxiety and behavioral changes predominantly in male offspring—a finding with striking implications for families in Thailand and around the world (Daily Mail).

A landmark study has shattered the myth that hours in the gym are necessary for effective muscle growth, revealing that only thirty minutes of targeted resistance training twice a week is enough for significant results. This breakthrough comes from an eight-week clinical trial led by an exercise scientist at Lehman College and published in Medicine & Science in Sports & Exercise, offering new hope to time-starved Thais eager to improve their health without upending busy schedules (Earth.com).

A fresh wave of contraceptive access efforts is unfolding in New York, even as funding strains and policy shifts reshape services. At a large state university in upstate New York, emergency contraception is now available through a vending machine, helping reduce cost, stigma, and travel time. As clinics adapt to changing policies, these campus innovations provide practical models for health workers and policymakers worldwide, including Thailand, where reproductive services remain unevenly distributed.

A recent advice column published by Slate captured viral attention by addressing a relatable and somewhat awkward question: can an adult penis really shrink over time, or might it just seem that way? The letter writer, reflecting on a sexual encounter with an ex-boyfriend after five years apart, noted that one part of her ex “seemed… smaller than before.” This personal observation sparked a larger conversation on whether penis size can change, what could cause such changes, and whether memory plays tricks on us. Recent research, expert opinions, and medical consensus shed important light on these sensitive, yet significant, questions for both Thai and international audiences.

A groundbreaking new study has revealed the essential role of an immune molecule, interleukin 34 (IL34), in fine-tuning brain development—a discovery that could reshape understanding of neurodevelopmental and neurodegenerative disorders. Conducted by researchers at Duke University and published in the journal Immunity on July 2, 2025, the study finds that IL34 acts as a key messenger, directing the brain’s own immune cells, known as microglia, on when and how to “prune” connections between neurons in early life. This process of synaptic pruning is fundamental, as it creates stronger, more efficient neural pathways underlying emotion, decision-making, and learning abilities (Duke University Medical School).

A recent eight-week study shows you can build noticeable muscle with just two 30-minute resistance workouts each week. Conducted by researchers at Lehman College and published in Medicine & Science in Sports & Exercise, the findings challenge the idea that long gym hours are essential. For busy professionals, students, and older adults in Thailand, this offers a practical path to better health without major schedule changes.

The trial involved 42 experienced lifters who were not professional athletes. Participants completed a core routine of nine movements—squats, rows, lat pulldowns, leg presses, and more—twice weekly. Each session lasted exactly 30 minutes, including warm-ups and brief rests. Half trained to absolute failure, the other half stopped two reps short as a safety measure. After eight weeks, both groups showed similar gains in muscle size and strength.

A new study from a leading university explores why neurodevelopmental diagnoses may show gender differences. Focused on PFHxA, a PFAS chemical found in packaging and stain-resistant fabrics, the research reports that prenatal and early-life exposure in mice led to anxiety, memory challenges, and reduced activity mainly in male offspring. Female offspring appeared less affected. Although conducted in animals, experts say the findings prompt important questions about environmental exposure and child development worldwide, including Thailand.

A new study identifies interleukin-34 (IL-34) as a critical cue that guides early brain development by directing microglia, the brain’s immune cells, on when to prune synapses. Proper IL-34 timing helps build resilient neural networks and supports later emotional health, learning, and cognition. Researchers describe IL-34 as a signal that tells microglia when to start and stop pruning during infancy.

Traditionally, microglia were seen mainly as defenders against infection. The findings now show they actively shape brain architecture as well. Supported by national health research funding and dementia-focused philanthropic support, the work demonstrates that normal IL-34 signaling enables microglia to engage at the right moments. When IL-34 functions correctly, pruning proceeds in a balanced, developmentally appropriate way.

A surge in health-conscious supplement use has brought a renewed warning about vitamin B6 toxicity, as fresh research and regulatory concern reveal that excessive intake may be harming more people than previously recognized. Australia’s medicines regulator, the Therapeutic Goods Administration (TGA), recently admitted it may have underestimated the scope of vitamin B6 side effects—especially nerve damage linked to prolonged high-dose use—prompting the body to reconsider how this over-the-counter supplement is sold (The Conversation).

A new study from Karolinska Institute in Stockholm provides fresh evidence that the adult brain can generate new neurons, even in old age. Published in Science, the findings challenge the belief that brain growth ends in childhood and open doors to potential treatments for neurological and mental health conditions. For Thai readers, the research highlights implications for dementia, stroke recovery, and lifelong learning in an aging society.

Researchers examined brain tissue from 46 individuals aged from infancy to 78 years, using advanced single-cell genomics. They focused on the hippocampus, a region essential for memory and learning, and found neural progenitor cells actively dividing in adulthood alongside mature neurons. The results align with animal studies that have long shown adult stem cells in the brain.

Air quality is a pressing health issue in Thai cities, where pollution levels surge during dry seasons. Groundbreaking research by a leading U.S. health institute links fine particulate matter to more cancer-driving genetic mutations in the lungs of nonsmokers. This points to environmental roots of lung cancer and underscores the urgency of cleaner air in urban Thailand.

Lung cancer is not solely a smoker’s disease. Across Thailand and Asia, many patients are nonsmokers. The NIH study combined tumor samples with local air data and found that residents in high PM2.5 areas carry a heavier burden of driver mutations in tumors. This suggests polluted air damages DNA and sparks cancer pathways even without tobacco exposure. The findings align with regional patterns where air pollution poses a notable risk to women and older adults.

Social media has exploded with claims that adding a pinch of salt or electrolyte powder to your water boosts hydration, but are these new habits really necessary—or even safe—for most people? Recent research and expert consensus suggest that while electrolytes play a vital role in our bodies, most healthy individuals in Thailand and globally can get what they need through the foods they eat, without resorting to expensive supplements or trendy drinks.

A new wave of research is shedding light on why seemingly healthy people face unexplained fatigue, persistent hunger, and difficulties with weight management—tracing the problem to a common but little-understood pattern: blood sugar “dips” after meals. Widespread adoption of continuous glucose monitors among non-diabetics, coupled with large-scale nutritional studies, is revealing how swings in blood glucose affect not only physical health, but also mood and everyday eating habits.

For Thai readers, where rising rates of diabetes, prediabetes, and metabolic disorders are public health concerns, this research holds surprising lessons for anyone aiming to boost energy, manage hunger, or guard against chronic illness. The new findings offer practical, science-backed strategies to stabilize blood sugar for improved well-being—no medical device required.

A recent study has detected microplastics in the reproductive fluids of both men and women, sparking global discussion about the potential consequences for fertility and reproductive health. Presented at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE), this research represents one of the first times microplastic contamination has been systematically documented in ovarian follicular fluid and semen, shifting the spotlight from environmental and dietary exposure toward intimate human biological systems. The findings urge both the scientific community and the public to reflect on the far-reaching impact of plastic pollution and what it could mean for future generations, including here in Thailand.

A new international study reveals microplastics in both female follicular fluid and male semen, raising questions about potential effects on fertility. Shared at a global reproductive health conference, the findings mark one of the first systematic detections of microplastics in these intimate fluids, expanding the conversation from environmental exposure to human biology. For Thai readers, the results highlight how plastic pollution could affect future generations and daily life in Thailand.

Recent scientific findings have shed new light on how alcohol consumption poses growing health risks as people age, challenging long-held beliefs about “safe” drinking levels for seniors. These insights come as the number of older adults in Thailand steadily rises, making it crucial for families and healthcare professionals to reconsider their approach to alcohol use among the elderly.

Alcohol has long been recognized as a health risk at any age. However, new research highlighted by a comprehensive report in The New York Times reveals that as individuals age, the same alcoholic intake can cause far more harm than in younger years. According to the director of the Center for Addiction Research & Education at the University of Florida, alcohol “affects virtually every organ system in the body,” with pronounced effects in older adults whose organs may already be experiencing age-related decline (nytimes.com).
