Scientists have demonstrated that select human gut bacteria can bioaccumulate and sequester PFAS ‘forever chemicals’, increasing faecal excretion in humanized mice. The findings reveal a potential microbiome-based strategy to reduce PFAS body burden, though clinical benefit in humans remains unproven.

Water fluoridation is effective in preventing tooth decay overall, but there are greater benefits for children from lower socioeconomic backgrounds, University of Queensland research has found.

Young people with friends who vape are 15 times more likely to use e-cigarettes, and more adolescents are turning to illicit cannabis products, University of Queensland research has found.

Researchers surveyed over 1,000 university students and found that lactose intolerance, especially when accompanied by gastrointestinal symptoms, is linked to more frequent nightmares and poor sleep. Only a small minority reported that food affected their dreams, highlighting a specific risk for those with food sensitivities.

Quitting smoking is linked to greater long-term waist circumference gain, but this effect may be due to shared genetics rather than quitting itself. Increased physical activity consistently helped limit waist expansion across all genetic backgrounds.

Researchers have recovered and sequenced Mycobacterium lepromatosis genomes from 4,000-year-old human remains in Chile, providing the first molecular evidence of ancient leprosy in the Americas. The findings reveal the deep evolutionary roots and complex spread of Hansen’s disease long before European contact.

A large multicenter trial found that a 12-week personalized exercise therapy and self-management support program produced a small but statistically significant improvement in health-related quality of life for adults with multimorbidity. The intervention was safe, but its clinical relevance remains uncertain, as only self-rated health showed a significant benefit over usual care.

This review highlights how the unique stressors of space travel, radiation, microgravity, and circadian disruption impact astronauts’ gut microbiomes, with potential consequences for their mood, cognition, and immunity. The authors call for targeted microbiome monitoring and dietary interventions to protect astronaut mental health on future missions.

Researchers using cardiac MRI have found that long-term exposure to air pollution is associated with early signs of heart damage, according to a study that was published today in Radiology, a journal of the Radiological Society of North America (RSNA).

GABA, or gamma-aminobutyric acid, is an amino acid functioning as the principal inhibitory neurotransmitter that can act on the brain to slow or stop the reception of certain signals to the brain, leading to a calmer and more relaxed state.

A new study has identified early-pregnancy gut microbiota signatures associated with the development of gestational diabetes mellitus, a metabolic disorder that carries substantial risks to both maternal and fetal health.

While glucose, or sugar, is a well-known fuel for the brain, Weill Cornell Medicine researchers have demonstrated that electrical activity in synapses—the junctions between neurons where communication occurs—can lead to the use of lipid or fat droplets as an energy source.

Schoolchildren born late in the year are at greater risk of developing mental health problems compared with their older peers, according to a new study.

Epilepsy is among the most common neurological conditions, marked by unpredictable seizures, accidents and injuries, reduced quality of life, stigma and-in the worst case-premature death.

The innate immune system is the body's first line of defense against pathogens and foreign substances. An essential component of this system are pattern recognition receptors, which recognize non-self RNA - such as that from viruses and bacteria - and trigger an immune response.

Acquired immune deficiency syndrome, or AIDS, caused by the human immunodeficiency virus (HIV), weakens the body's immune system and can be life-threatening if left untreated.

Uterine cancer incidence and mortality rates are projected to increase significantly over the next three decades in the United States, with incidence-based mortality expected to be nearly three times higher in Black women compared with white women by 2050.

Researchers at Tohoku University have discovered that an oral drug called MA-5 can improve both heart and muscle problems in Barth syndrome, a rare genetic disorder affecting 1 in 300,000 births worldwide with no current cure.

A new study published in The Lancet has raised urgent concerns about the global health consequences of recent cuts to U.S. foreign aid.

In the fight against cancer, immunotherapy - which aims to boost the body's natural defences against cancer - is experiencing remarkable growth. Most of these treatments are based on CD8 T lymphocytes, ''killer cells'' able to eliminate diseased cells.
