Vitamin B12 plays a critical role in red blood cell formation and genetic function. In the United States, about one in eight adults 19 and older are deficient, a statistic prompting attention among older adults, vegetarians, and people with digestive conditions. New guidance highlights that when you take B12 may affect how well it works. For Thai readers, this adds a practical angle to everyday health routines.

Research shows the body’s absorption of B12 can be influenced by timing. Experts recommend taking B12 in the morning, ideally before breakfast. A noted plant-based nutrition expert points out that absorption peaks roughly seven hours after intake, suggesting that a morning dose can help sustain benefits throughout the day. This approach is particularly relevant for those who rely on supplements to meet daily needs.

A recent study from a leading university reveals a startling estimate: the average human brain may contain microplastics comparable to five plastic bottle caps. The discovery raises urgent questions about health risks as tiny particles increasingly permeate environments and human bodies.

Researchers report that brain samples collected in 2024 contained nearly 50% more microplastics than samples from eight years earlier. On average, about seven grams of plastic—roughly the weight of a disposable spoon—was found in brain tissue. Notably, individuals with dementia showed higher levels, suggesting a possible link with a more permeable blood-brain barrier that struggles to remove toxins.

New research raises questions about gadolinium-based contrast agents (GBCAs) used in MRI scans. These agents improve image clarity and help diagnose tumors, vascular issues, and other conditions. Yet emerging findings suggest gadolinium deposits could form toxic materials in the body if not fully expelled, prompting a careful review of safety practices for patients in Thailand and beyond.

Gadolinium is a rare earth metal. In MRI, it is given in a chelated form to reduce risk. The latest studies, however, highlight scenarios where gadolinium may accumulate if scans are repeated over time. This has implications for patients who undergo multiple MRIs, especially children and those with kidney concerns.

In an unsettling revelation, a recent study by the University of New Mexico has uncovered that the average human brain may now contain microplastics equivalent to five plastic bottle caps. This discovery has sparked significant concern about potential health implications as these tiny plastic particles increasingly permeate our environment and, disturbingly, our bodies.

The groundbreaking study revealed that brain samples taken in 2024 contained nearly 50% more microplastics than those found just eight years earlier. On average, an astonishing seven grams of plastic, roughly the weight of a disposable spoon, was discovered in human brain tissue. Of particular concern is the finding that individuals with dementia had higher microplastic levels in their brains, potentially due to a more porous blood-brain barrier that is less effective at removing toxins.

A new study points to weight training as a potential tool to reduce dementia risk, offering hope for an aging global population. Researchers from UNICAMP in Brazil found that resistance exercise may play a meaningful role in delaying or preventing dementia, a condition characterized by memory loss and behavioral changes.

Dementia affects around 55 million people worldwide, and numbers are rising with aging populations. While there is no cure, lifestyle choices are a central defense. Prior research suggests lifestyle changes could prevent up to 45% of dementia cases, and the latest study reinforces resistance training as a valuable preventive measure.

A landmark international study has identified a new blood group system, unveiled after more than five decades of investigation. Researchers from the United Kingdom and Israel describe the MAL blood group, a finding sparked by a puzzling case from 1972. National Health Service hematologist Louise Tilley calls the discovery “a huge achievement,” marking the culmination of years of teamwork.

In 1972, a pregnant patient’s blood sample lacked a surface molecule once thought universal on red blood cells. It took over 50 years to recognize this anomaly as a distinct blood group system. The 2024 study decoded the genetic basis of this type, AnWj-negative, identifying mutations in the MAL genes. This work deepens our understanding of human blood diversity and could influence how some patients receive transfusions.

In an age where many health-conscious individuals seek ways to enhance nutrient intake, the role of vitamin B12 in maintaining vital bodily functions has never been more evident. With a staggering 12.5% of the U.S. population aged 19 or older deficient in this crucial vitamin, timely consumption of B12 is gaining attention, particularly among groups like older adults, vegetarians, and people with digestive disorders. Recent insights suggest that the time you take your B12 supplement can play a pivotal role in its efficacy, illuminating an often overlooked facet of nutritional science.

Air hunger is a lesser-known anxiety symptom that can quietly disrupt daily routines. It describes the feeling of not getting enough air even when oxygen levels are normal. Medically, this condition relates to dyspnea, but its link to anxiety makes the sensation distinct and more complex. Recognizing air hunger helps people understand a frustrating, often misunderstood experience.

For readers in Thailand, the message resonates amid Bangkok’s fast pace and air quality challenges. Stress can trigger the body’s “fight or flight” response, a familiar concept for those facing exams, presentations, or high-pressure work. In modern life, this reflex can overshoot, contributing to episodes of air hunger rather than protecting us.

A recent study has unveiled a promising approach to combating the onset of dementia, a progressive brain condition affecting millions globally. Researchers from the State University of Campinas (UNICAMP) in Brazil have discovered that weight training might play a crucial role in reducing dementia risk, offering hope to an ageing population facing the rising tide of this syndrome marked by memory loss and behavioral changes.

Dementia affects an estimated 55 million people worldwide, a number anticipated to increase as populations age. With no known cure, lifestyle changes remain a primary defense against the disease. Previous research has suggested that lifestyle adjustments could prevent up to 45% of dementia cases, and the latest study adds to this body of evidence by identifying resistance exercise as a key preventive measure.

In a startling revelation, a recent study by child health experts underscores the gravity of antimicrobial resistance (AMR), with more than three million child deaths attributed to drug-resistant infections in 2022 alone. This surge in fatalities starkly illustrates AMR’s role as a formidable global health menace, uniquely threatening children in Africa and Southeast Asia. AMR occurs when microbes adapt, rendering antibiotics ineffective, a scenario that significantly imperils public health worldwide.

In a revolutionary discovery, researchers from the Karolinska Institute in Stockholm and the University of Groningen have found that our pupil size changes in harmony with our breathing pattern—a phenomenon now known as the “pupillary respiratory phase response.” This cutting-edge research, recently published in the Journal of Physiology, adds a new dimension to our understanding of the body’s internal rhythms, revealing a connection that could have significant implications for both vision science and medical diagnostics.

A new study highlights a stark truth: more than three million child deaths in 2022 were linked to drug-resistant infections. The finding underscores antimicrobial resistance (AMR) as a major global health threat that disproportionately affects children in Africa and Southeast Asia. AMR occurs when microbes adapt and antibiotics fail to work, risking public health worldwide.

The analysis draws on data from trusted institutions, including the World Health Organization and the World Bank. It shows a troubling rise in AMR-related infections among children over just a three-year window, a trend that may have been accelerated by the COVID-19 pandemic. Experts describe a tenfold increase in AMR cases, calling for immediate action. Contributing factors include the widespread misuse and overuse of antibiotics. Antibiotics are frequently prescribed to prevent infections ahead of surgeries or chemotherapy, even though they do not treat viral illnesses such as colds, flu, or COVID-19.

Recent research from the University of Southampton presents compelling evidence that dietary habits in one’s 60s could have significant implications for health outcomes, particularly regarding hip fractures and cardiovascular disease. Over a period of two decades, the study tracked nearly 3,000 individuals who began the research around the age of 65. The findings suggest a clear association between a “prudent” diet and a reduced risk of both bone fractures and heart disease mortality, offering valuable insights into preventative health measures for older adults.

Robert F. Kennedy Jr., serving as the U.S. Secretary of Health, has ignited debates concerning vaccines through his recent actions which, according to critics, undermine confidence in vaccination programs. During his Senate confirmation hearings, Kennedy claimed to be a vaccine proponent. However, his subsequent initiatives—from halting funding for vaccine hesitancy research to redirecting resources away from novel vaccine development—suggest otherwise.

The National Institutes of Health has ceased funding numerous projects aimed at understanding and addressing vaccine hesitancy, while the Centers for Disease Control and Prevention (CDC) canceled an advertising campaign designed to promote flu vaccinations. Kennedy has publicly doubted the impartiality of CDC scientists, claiming severe conflicts of interest—a statement many experts debunked as misleadingly inaccurate.

A high-profile American official’s stance on vaccines has sparked a wide debate about vaccine confidence and public health messaging. Critics argue that recent moves under a U.S. health leadership team undermine trust in vaccination programs, while supporters say the actions reflect a broader review of public health priorities.

During confirmation hearings, the official described themselves as a vaccine advocate. Yet after taking office, actions including redirecting funds away from vaccine hesitancy research and shifting resources away from early-stage vaccine development have raised questions about long-term vaccination strategy. No matter the stance, the impact on public trust is clear, particularly as communities confront preventable diseases.

Microplastics are tiny plastic fragments smaller than 5 millimeters that pervade our environment and increasingly enter human bodies. Recent research in the United States found microplastics in autopsy brain tissue, highlighting the particles’ ability to cross the blood-brain barrier and accumulate in organs. While the full health impact remains under study, these findings add to growing evidence of widespread exposure since earlier research in 2016.

The relevance for Thailand is clear. As Thai consumers increasingly enjoy processed foods and rely on plastic packaging, the risk of microplastic contamination rises. Data from various international studies indicate that a large share of protein-rich foods, including seafood popular in Thai cuisine, contain microplastics, with processed products showing higher levels. Given Thailand’s long coastline and seafood-centric diet, this issue has local resonance. Breaded shrimp and other commonly eaten items have shown notable microplastic presence in some analyses.

Microplastics, the tiny plastic fragments under 5 millimeters in diameter, have emerged as pervasive pollutants in our ecosystem, infiltrating even human bodies. Recent studies in New Mexico have discovered microplastics in autopsy samples from human brains, revealing an alarming capacity to breach the blood-brain barrier and accumulate in our tissues. This breakthrough, initially reported on in 2024, underscores the escalating presence of microplastics, which has significantly increased compared to studies conducted in 2016. Despite the omnipresence of these particles, which originate from the breakdown of larger plastic items and are distributed through environmental pathways such as landfills and water systems, the full extent of their impact on human health remains uncertain.

Perimenopause, often misunderstood as a sudden transition late in a woman’s life, can begin as early as one’s 30s, introducing a myriad of surprising symptoms. This transitional phase, preceding menopause, is gaining attention for the range of unexpected experiences it presents to women. It’s vital for Thai women to understand these developments to accurately interpret their health changes and seek appropriate care.

For many Thai women, the notion of menopause has always been associated with an abrupt cessation of menstruation typically happening in their 50s, but recent insights highlight that perimenopause can commence much earlier. Dr. Natalia Llarena, an OBGYN specializing in reproductive endocrinology, emphasizes that perimenopause can start before the age of 40 and persist for several years. Importantly, it carries distinctive symptoms like irregular menstrual cycles, hot flashes, and mood swings which are frequently overlooked.

Researchers at the Karolinska Institute in Stockholm and the University of Groningen report a surprising link between how we breathe and how our pupils adjust. The study introduces the pupillary respiratory phase response, a phenomenon where pupil size changes with each breath. Published in the Journal of Physiology, the work adds a new layer to our understanding of the body’s rhythms and could influence vision science and medical diagnostics.

Traditionally, pupil size is known to respond to lighting, focus, and mental effort. The new findings show breathing as a fourth trigger. Pupil size tended to be smallest during inhalation and largest during exhalation, a pattern observed in more than 200 participants across different lighting, breathing methods, and cognitive tasks.

New findings from a large 20-year study suggest that the dietary choices people make in their 60s can influence two major health risks for older adults: hip fractures and heart disease. The research followed nearly 3,000 participants who started around age 65, identifying a link between a “prudent” diet and lower rates of both bone fractures and cardiovascular mortality. The study supports the idea that what we eat in later life matters for long-term health.

Once a symbol of prosperity in India, the pot belly has shifted from status symbol to a mounting health concern. A 2021 Lancet study positioned India second in global obesity rates, with about 180 million adults overweight or obese. Projections suggest this could rise to 450 million by 2050, approaching one‑third of the country’s population.

Central obesity, the fat that concentrates around the abdomen, poses distinct health risks beyond overall weight gain. Data from India’s National Family Health Survey shows more than 40% of urban women and 12% of men already face abdominal obesity. Alarmingly, nearly half of women aged 30–49 meet the country’s abdominal obesity criteria, defined by waist measurements above regional thresholds.

The bustling world of A.D.H.D. diagnosis and treatment has come under fresh scrutiny as new research questions long-held beliefs about the disorder’s nature and treatment. A detailed New York Times article by Paul Tough, “Have We Been Thinking About A.D.H.D. All Wrong?,” dives deep into the evolving understanding of Attention Deficit Hyperactivity Disorder (A.D.H.D.) and how it is frequently addressed through medical treatments, challenging the current paradigm with emerging scientific insights.

Attention Deficit Hyperactivity Disorder (ADHD) is undergoing re-examination as new research questions long-held assumptions about its nature and treatment. A recent New York Times piece by Paul Tough, Have We Been Thinking About ADHD All Wrong?, probes how the disorder is identified and managed, challenging prevailing approaches with fresh scientific insights.

ADHD diagnoses rose sharply in recent decades, from about 3% of American children in the early 1990s to roughly 11% today. The surge coincates with the 1990s, when stimulant medications such as Ritalin became widely prescribed. The landmark Multimodal Treatment of ADHD (MTA) study initially supported stimulant use for symptom relief. Yet long-term follow-ups raised questions about the durability and scope of medication benefits, with researchers including psychologist James Swanson highlighting evolving concerns.

Earwax serves a purpose beyond being merely bothersome. Medical experts say most people don’t need to remove it routinely. Dr. Erich P. Voigt of NYU Grossman School of Medicine notes that earwax acts as a natural barrier against infections and moisture, helping prevent dryness and itchiness. This is particularly relevant for Thailand’s humid climate, where ear hygiene often raises questions.

Experts describe earwax as a self-cleaning “conveyer belt” of skin. Dr. Lawrence R. Lustig of Columbia University explains that earwax and canal oils migrate outward, gradually releasing wax from the ear canal without manual intervention. Data from reputable medical sources supports the idea that the body typically manages earwax on its own.
