Understanding sevoflurane-induced neurogenesis inhibition and cognitive dysfunction in children

Every year, millions of infants and children undergo surgery under general anesthesia in the world. Sevoflurane is a commonly used pediatric anesthetic. Its exposure during brain development has been shown to inhibit neurogenesis and cause cognitive dysfunction in animal models.

Vitamin A derivative suppresses immune response and cancer vaccine efficacy

Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A-all-trans retinoic acid-compromises both the body's normal anti-cancer immune response and, in a different context, the efficacy of a promising type of cancer vaccine.

"Blue zones" longevity claims validated by new research

A new peer-reviewed paper published in The Gerontologist provides the most comprehensive scientific response to date addressing recent critiques of the so-called "blue zones," regions of the world known for unusually high concentrations of people living long, healthy lives.

Study sheds light on rare emotional and physical responses during orgasm

When some women orgasm, they experience unusual physical and emotional responses such as laughing, crying, headaches, tingling, foot pain, nosebleeds and more.

Orthopedic encounters could play key role in early detection of intimate partner violence

A study by researchers at Mass General Brigham highlights the opportunity for orthopedic surgeons to play a critical role in identifying patients who have experienced intimate partner violence (IPV).

Finger-prick blood tests enable remote detection of Alzheimer’s biomarkers

A groundbreaking international study has demonstrated that Alzheimer's disease biomarkers can be accurately detected using simple finger-prick blood samples that can be collected at home and mailed to laboratories without refrigeration or prior processing.

COVID-19 immunity stays specific and barely boosts protection against common cold coronaviruses

This study shows that SARS-CoV-2 infection and vaccination generate strong, highly specific spike-binding immune responses with only modest effects on immunity to endemic common cold coronaviruses. Pre-existing coronavirus immunity patterns remain largely intact, indicating that SARS-CoV-2 has integrated into the human viral landscape without broadly reshaping cross-reactive protection.

Gut microbes shown to directly shape brain function and evolution

A groundbreaking new study reveals that changes to the gut microbiome can change the way the brain works.

Why intuition matters more than facts in flu vaccination decisions

Flu infections are rising sharply across the United States, contributing to at least 81,000 hospitalizations and 3,100 deaths so far this season, according to the U. S. Centers for Disease Control and Prevention.

Diabetes could drain up to INT$78.8 trillion from the global economy by 2050, study finds

This global macroeconomic analysis estimates that diabetes mellitus will cost the world economy INT$10.2 trillion between 2020 and 2050, rising to INT$78.8 trillion when unpaid informal caregiving is included. Using a health-augmented economic model across 204 countries, the study shows that informal care is the dominant and most underestimated driver of diabetes-related economic losses worldwide.

AI method sharply improves noise removal in brain imaging

Obtaining clearer functional MRI data about the brain and its disorders is possible using artificial intelligence, according to Boston College researchers who reported recently in Nature Methods that they developed an AI-assisted method to remove "noise", or image distortions, caused by movement, heartbeat, and other factors.

New guidelines aim to standardize diagnosis of canine dementia

An international working group of canine cognition experts has released a set of guidelines for veterinarians to use in diagnosing and monitoring canine cognitive dysfunction syndrome (CCDS), or canine dementia.

Income sufficiency emerges as key factor in early brain development

Decades of research show that early psychosocial stress, including chronic exposure to adversity, can shape how a child's brain develops, with effects that last well beyond childhood. But families rarely experience just one source of stress at a time.

Common blood signals explain why chronic diseases cluster as we age

This population-based study shows that shared and pattern-specific blood biomarkers reflect biological vulnerability underlying multimorbidity and the pace at which chronic diseases accumulate in older adults. Metabolic and systemic stress markers such as GDF15, HbA1c, cystatin C, and insulin consistently tracked higher disease burden and faster accumulation, with findings replicated across cohorts.

Maintaining a healthy weight may help avoid low back pain

Low back pain (LBP) is a prevalent condition associated with disability, work loss and economic burden to healthcare. Significant risk factors include poor sleep, physical and psychological stress, inactivity, advanced age and smoking.

Inhalable nanotherapy can activate the immune system against checkpoint-resistant melanoma

Immune checkpoint molecules play a crucial role in keeping the immune system in balance and preventing an attack on the body's own cells.

Injectable paste from human skin cells may improve breast reconstruction

Removing part or all of the breast during breast cancer treatment is a potential outcome for some people.

Calculator offers accurate scoring of multilingual language ability

More than half of the world's population speaks more than one language-but there is no consistent method for defining "bilingual" or "multilingual." This makes it difficult to accurately assess proficiency across multiple languages and to describe language backgrounds accurately.
