Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth.

As parasites become increasingly resistant to existing drugs, researchers at the University of California, Riverside are working to develop a new generation of treatments for two serious infectious diseases: malaria and babesiosis.

The amino acid arginine helps to keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes.

The COVID-19 pandemic highlighted some severe consequences of unchecked respiratory disease, including cytokine storm.

A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania.

A scientific collaboration between the University of Bath (UK) and the UMass Chan Medical School (USA) have determined how a specific type of white blood cells, called neutrophils, move through the body.

Exposure to a widely used herbicide during the middle months of pregnancy may increase the chance of giving birth too early, before 37 weeks, a new study shows.

Sepsis triggers widespread inflammation, circulatory failure and metabolic stress, and cardiac dysfunction is a common complication associated with sharply poorer outcomes.

Protein-fortified foods are popping up everywhere, from cereal and coffee to even protein water. But a new review covering over 350 papers on protein restriction and aging-publishing July 31 in the Cell Press journal Cell Press Blue-suggests that consuming less protein could have greater health benefits and could, in some cases, extend lifespan.

If it feels harder to keep the same doctor, you're not imagining it. Healthcare leaders say retirements, burnout and changing workforce expectations are making it complicated to keep experienced clinicians in place.

Researchers at the MRC Laboratory of Medical Sciences (LMS), Imperial College London and UCL Genetics Institute have created a detailed map of cells within breast tumors and identified distinct neighborhoods of proliferating and dormant cells.

A new approach to defining obesity could help physicians better determine which patients need more intensive treatment by focusing on the effects of excess adiposity on organs and tissues rather than relying primarily on whether a person meets a set of metabolic risk thresholds.

An estimated 10 million Americans have atrial fibrillation (AFib), according to the National Institutes of Health's National Heart, Lung, and Blood Institute.

A $1.5M grant has been awarded to William Van Nostrand, co-executive director of the University of Rhode Island's George & Anne Ryan Institute for Neuroscience and professor of pharmaceutical and biomedical sciences in the URI College of Pharmacy, to study cerebral amyloid angiopathy (CAA), a disease prevalent in the elderly population and commonly found in patients with Alzheimer's disease.

Hutchinson-Gilford progeria syndrome (HGPS) is a genetic disorder that causes remarkable premature aging.

The study, which tracked more than 500 Spanish girls between the ages of 7 and 10, links the presence of certain fungicides in urine to early menarche and that of the insecticide chlorpyrifos to delayed menarche, highlighting the impact of pesticides on pubertal development.

High salt (HS) intake is a major global health concern, closely linked to hypertension and growing evidence of cognitive and emotional decline.

While existing digital health tools can provide valuable information to offset poor nutrition, older adults with pre-frailty and frailty want to engage with these tools easily, to support their autonomy, dietary self-management and healthy aging.
