A newly published Finnish study demonstrates that, in addition to temperature, air humidity is a significant determinant of physiological strain during sauna bathing.

Lung infections are a constant risk for people living with cystic fibrosis (CF), a life-threatening genetic disorder which impairs lung function, predisposes people to persistent airway infections and exposes them to acquiring multidrug resistant infections.

A person's posture appears to affect their emotions and decision-making ability more than they realize, according to new research from McGill University.

A novel AI model can use information collected during routine sleep studies to identify patients' long-term health risks, according to a new study published in Nature Communications.

Both full and limited endoscopic sinus surgery significantly improve quality of life in patients with chronic rhinosinusitis with nasal polyps, according to a recent study published in Allergy.

Your neighborhood's "streetscape"-the physical environment of your street-is something that you have probably never consciously thought about, despite seeing it every day.

What enables us to sustain effort toward goals, even when the task becomes increasingly difficult? A recent study by researchers at Nagoya University in Japan revealed the underlying brain mechanism, showing that orexin neurons play a crucial role in driving and regulating motivated behavior.

A narrative review links reduced SCFA-producing gut bacteria and altered microbial metabolism with Alzheimer’s disease, while early evidence suggests similar changes may appear before cognitive symptoms. Mediterranean, DASH, MIND, and prudent diets are associated with beneficial microbial profiles, but direct evidence connecting diet, the microbiome, and amyloid pathology remains limited.

Researchers analyzing 1,518 South African household participants found that higher pre-season antibody titers were associated with lower infection risk for three of four influenza viruses studied. Children remained more susceptible after accounting for measured exposure and antibody titers, while younger children shed viral RNA longer than older adults.

Researchers surveyed 10,618 adults across 1,372 localities in the world’s 10 most populous countries and matched their responses with average 2019-2021 PM2.5 concentrations. Higher PM2.5 exposure was associated with lower air-quality knowledge but greater concern and more frequent protective behaviors, with patterns differing across demographic groups.

An exploratory randomized trial found that 200 g of raw tomatoes plus 50 g of tomato sauce daily for six weeks produced a greater reduction in CAP-defined hepatic steatosis than a tomato-free diet in adults with MASLD. The improvement occurred without major weight or metabolic changes, but larger and longer trials are needed to confirm its clinical significance.

An evidence review of international research suggests widespread misconceptions within the medical community about early milk production, pacifiers and breast pumps may be undermining breastfeeding success in the critical first days after birth.

A new path has opened toward stopping cancer-associated cachexia, a devastating complication that gradually wastes patients away.

In 3,895 older adults, moderate daytime cortisol variability was associated with better cognition and slower decline, while the highest daily cortisol exposure was linked to poorer cognition and faster decline. Cortisol patterns differed between Black and White participants, but their relationships with cognition were similar, and none predicted incident Alzheimer’s disease.

Among 1,058 Danish men, higher body fat percentage was associated with lower total sperm count and altered reproductive hormone levels, but not testicular volume. Body fat percentage showed stronger links with several semen measures than BMI or waist-to-height ratio, with the sperm-count association strengthening among men with normal BMI.

Researchers linked persistent low income and financial hardship across early and mid-adulthood to poorer processing speed and verbal memory at age 53 in a British birth cohort. Neuroimaging suggested greater vulnerability to later brain atrophy among men, people from disadvantaged childhood backgrounds, and APOE-ε4 carriers, although these subgroup findings require replication.

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, report researchers at Institute of Science Tokyo, Japan.

Hepatic encephalopathy (HE) is a neurologic complication of advanced liver disease, causing impaired functioning, reduced quality of life (QOL), and increased hospitalisation and mortality.

How does the brain make sense of what we see, hear, and feel—and transform these separate signals into a coherent perception of the world?

Two plants that cause neurotoxicity and paralysis in the tiniest doses are also known to counter pain, malaria, cancer and pests.
