A groundbreaking study published in the peer-reviewed journal Science Advances has revealed that everything we perceive visually is not in real time, but actually an average of what we saw up to 15 seconds ago—a revelation that could fundamentally reshape our understanding of human perception and consciousness. This research, led by teams from the University of Aberdeen and University of California, Berkeley, suggests our brains constantly merge recent visual history to present us with a stable, coherent world—essentially tricking us into viewing a smooth, illusionary reality (Popular Mechanics; Science.org; UNILAD).

A landmark study in Science Advances reveals that our visual perception is not in real time; instead, the brain blends recent images over roughly the last 15 seconds to create a stable view of the world. This finding shows how the mind smooths rapid changes to maintain coherence, a process that shapes everyday life from driving to learning.

For Thai readers, the implications are immediate. Visual processing affects safety on crowded roads, athletic performance, and the way information is presented in classrooms and on screens. In a society saturated with smartphones, understanding this lag helps people navigate a fast-moving environment more effectively and with greater awareness of perceptual limits.

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.

A groundbreaking study from Sweden has provided compelling evidence that the adult human brain continues to generate new neurons well into old age, debunking the long-standing belief that brain cell growth halts after childhood. This discovery, published in the journal Science and highlighted in a recent Gizmodo report, offers new hope for future treatments of neurological and psychological disorders, and reshapes our understanding of the brain’s lifelong potential.

For decades, it was widely believed—taught both in schools and medical textbooks—that the human brain reached its full complement of neurons in early life, and that no new neurons were formed past childhood. While previous studies hinted at ongoing brain cell growth, scientific opinion remained split, with some researchers finding scant evidence for adult neurogenesis and others reporting clear signs. The confusion was particularly acute when it came to humans, since much of the existing evidence came from studies in animals such as mice or pigs.

As the world continues to witness conflicts such as those in Gaza and Ukraine, public concern has focused on how the trauma endured by those caught in these crises might affect not only survivors, but also their children and grandchildren. The idea of trauma being somehow “etched” into our DNA and handed down to future generations has captivated the Thai public, especially given the country’s own turbulent history and collective memories of hardship. However, emerging scientific research reveals that the story is far more nuanced—and hopeful—than many headlines suggest.

Trauma is reshaping how Thai communities think about health across generations. The idea that hardship can become woven into our biology has long haunted Thailand’s historical narratives. New science, however, shows the body and mind can adapt and recover, offering practical paths for families.

Interest in transgenerational trauma has grown as researchers explore whether past family stress leaves lasting marks on gene activity. In Thailand, where stories of resilience run through national memory, the topic resonates deeply. Leading scientists caution that trauma is not a fixed fingerprint in the genome. Instead, biology demonstrates plasticity, opening actionable avenues for healing.

A recent research review has uncovered a striking connection between tinnitus, a persistent ringing or buzzing in the ears with no external cause, and one of the body’s most important restorative processes: deep sleep. With around 15% of the global population suffering from tinnitus—many experiencing significant distress, sleep disturbances, and even depression—this finding could signal new directions for symptom management and treatment for millions, including Thais impacted by this commonly misunderstood condition ScienceAlert.

A new review highlights a significant link between tinnitus—persistent ringing or buzzing in the ears with no external cause—and deep sleep, one of the body’s most vital restorative processes. About 15% of people worldwide live with tinnitus, and many endure distress, sleep disruption, and even depression. The findings could open new paths for managing symptoms and improving quality of life for millions, including Thais affected by this often misunderstood condition. Research by Oxford University neuroscientists points to shared brain activity during tinnitus episodes and slow-wave sleep, suggesting the brain’s sleep architecture may influence tinnitus intensity.

A groundbreaking Japanese study has revealed that vitamin C can help reverse age-related thinning of the skin by activating so-called “youth genes,” offering hope to many Thais concerned about healthy aging and skin rejuvenation. This research, published in the Journal of Investigative Dermatology on April 20, 2025, demonstrates for the first time that vitamin C works at the genetic level to promote thicker, healthier skin in ways that extend beyond its antioxidant reputation and traditional beauty claims (sciencedaily.com).

A growing body of research is shining a spotlight on so-called “superfoods”—such as honey, oysters, watermelon, ginger, and ginseng—for their potential benefits to male sexual health and fertility. According to a recent biochemical review published in the journal Current Research in Food Science, these foods may promote testosterone production, sperm quality, and erectile function, providing a natural alternative to pharmaceutical treatments and bringing renewed hope for men seeking to enhance their reproductive well-being (Physicians Weekly).

A growing body of research highlights so-called “superfoods” like honey, oysters, watermelon, ginger, and ginseng for potential benefits to male sexual health and fertility. A recent biochemical review in Current Research in Food Science suggests these foods may support testosterone production, sperm quality, and erectile function. The findings point to natural options that align with practical wellness goals for Thai readers.

In Thailand and around the world, interest in male sexual health and fertility is rising. Nations face concerns about declining birth rates and stress-related sexual function issues. Thai demographics show lower birth numbers alongside reports of male infertility. Many Thai men value evidence-based, natural approaches that honor cultural traditions about food as medicine.

A long-term study published in the journal Psychological Science has found little evidence supporting the widespread assumption that attending religious services leads to better mental health outcomes, raising questions about a relationship long thought to be positive and beneficial. The research, which analyzed nearly two decades of data from the British Household Panel Survey, revealed that frequent participation in organized religious gatherings had no clear association with improved mental well-being and, in certain instances, was followed by slightly worse symptoms.

A long-term analysis in Psychological Science questions the widely held belief that going to religious services reliably improves mental health. The study tracked nearly two decades of data from the British Household Panel Survey and found no clear link between frequent religious attendance and better mental well-being. In some cases, higher participation correlated with slightly worse mental health in following years.

Historically, many studies have suggested that religious involvement reduces depression, anxiety, and substance abuse. The proposed benefits are often attributed to social support, a sense of belonging, and coping strategies like hope and meaning-making offered by faith communities. However, new findings based on responses from over 29,000 British adults between 1991 and 2009 indicate the relationship may be more nuanced than previously thought. Researchers examined both within-person changes over time and comparisons between people with different levels of attendance to understand the true dynamics.

New research is turning kitchens into potential health hubs. Scientists increasingly highlight rosemary’s brain-protective, mood-supporting, and sleep-enhancing properties. A common herb found in many Thai and global dishes, rosemary—especially its carnosic acid component—has shown promise in fighting cognitive decline and reducing anxiety, while improving sleep quality. This emerging evidence invites Thailand’s aging and stress-prone society to consider dietary options as part of a holistic approach to wellness.

Thailand faces rising dementia and mental health challenges, mirroring global trends. Nutrition experts and neurologists emphasize diet as a modifiable risk factor. In Thai culture, the idea of “food as medicine” runs deep, with herbs such as holy basil and lemongrass playing important roles. Rosemary is increasingly available in urban markets and culinary communities, offering an accessible addition to Thai kitchens while aligning with contemporary wellness trends.

If you’ve ever gazed into the soulful eyes of your dog or pondered the enigmatic glance of your cat, you’ve likely wondered: does my pet truly understand me? Recent research—highlighted in a comprehensive feature by The Guardian—delves into the psychological worlds of dogs and cats, raising new questions and challenging old beliefs about our companion animals’ inner lives, especially as millions of Thai households share their homes with beloved pets (The Guardian).

Pet lovers in Thailand and around the world often wonder what goes on in a dog’s mind or a cat’s heart. A recent in-depth feature from The Guardian explores the psychology of dogs and cats, challenging long-held beliefs about their inner lives and what empathy truly means for our companion animals. The piece resonates with Thai households where pets are trusted sources of comfort in difficult times.

In Thailand’s bustling cities, millions of households rely on pets for emotional support. The Guardian’s stories recount terriers offering comforting licks, Labradors standing by grieving humans, and Cavachons soothing children with autism. While many Thai families instinctively view their pets as family, researchers question whether animal actions constitute human-style empathy or are driven by other factors such as emotional contagion or simple curiosity.

A groundbreaking new study suggests that the same mRNA technology powering Covid-19 vaccines could become a vital weapon in the quest to cure HIV, raising hopes among researchers and millions living with the virus worldwide. Australian scientists announced last week that their innovative mRNA-based method was able to flush dormant HIV out of its hiding places in laboratory experiments—a necessary step toward eliminating the virus entirely from the human body (nytimes.com).

A new study suggests the very mRNA technology behind Covid-19 vaccines could help finally cure HIV. Australian researchers report their mRNA-based method can flush dormant HIV from hiding places in laboratory tests, a key step toward eradicating the virus from the body.

For Thai readers, the news carries significant implications. Thailand faces one of Asia’s highest HIV burdens, with hundreds of thousands living with the virus. If proven safe and effective in humans, this approach could shorten treatment durations and improve quality of life for many in Thailand and around the world.

A recent study highlighted by Business Standard reveals that regular, moderate-to-high intensity exercise can serve as a powerful tool in significantly reducing the burden of negative thoughts such as rumination and worry—a finding that holds meaningful implications for mental well-being in Thailand and beyond (Business Standard). With negative thinking habits commonly linked to anxiety, depression, and reduced quality of life, this research offers a practical, accessible approach for individuals seeking to enhance their emotional resilience.

A new study highlighted by Business Standard shows that regular, moderate-to-high intensity exercise can significantly reduce negative thinking, including rumination and worry. For Thai readers, this provides a practical, accessible path to bolster emotional resilience and overall well-being. In a time of rising stress and economic pressures, exercise emerges as a usable tool alongside traditional mental health support.

Negative thinking—rumination and persistent worry—has long been linked to anxiety and depression and can lower quality of life. In Thailand, national surveys indicate a noticeable uptick in stress-related concerns in recent years, underscoring the need for everyday strategies to safeguard mental health. The latest findings align with a growing global emphasis on self-directed interventions that people can weave into daily life.

A new peer-reviewed study suggests that soluble fibre from oats may assist the body in expelling PFAS, the so-called forever chemicals. The finding provides a hopeful avenue for communities in Thailand and beyond concerned about persistent environmental pollutants. The study, published in Environmental Health on June 4, 2025, marks a cautious advance in reducing PFAS in humans.

PFAS are synthetic compounds used worldwide in non-stick cookware, stain-resistant fabrics, firefighting foams, food packaging, waterproof clothing, and cosmetics. Their durability makes them highly resistant to heat, oil, and water, but it also means they linger in the environment and in the human body for years. Research links PFAS exposure to cancers, fertility issues, developmental problems in children, thyroid disease, and immune system effects. In Thailand, concerns have grown as reports indicate PFAS contamination in drinking water, textiles, and household items, underscoring the need for protective public health measures.

A recent scientific breakthrough has found that a simple dietary supplement—soluble fibre from oats—may help the human body flush out toxic “forever chemicals” known as PFAS. This offers a glimmer of hope to communities in Thailand and around the world concerned about the health hazards of persistent environmental pollutants. The peer-reviewed study, published in Environmental Health on 4 June 2025, marks a significant step forward in the battle against chemicals that have long defied removal from our bodies.
