Short-lived radioactive isotopes, or radioisotopes, can image tumors or inflict high levels of cellular damage to them.

Lower intake of red and processed meat was associated with small reductions in all-cause, heart disease, cancer, and stroke mortality in a cohort of nearly one million US adults followed for decades. White-meat-only diets showed additional benefits in some subgroups, while vegetarian diets produced few consistent associations and were limited by small participant numbers and a single baseline dietary assessment.

Healthy plant-based diets rich in whole grains, legumes, fruits, vegetables, nuts, and seeds are associated with better glycemic control and a lower risk of type 2 diabetes. The review finds that food quality and processing matter more than simply avoiding animal foods, while unhealthy plant-based patterns and higher red and processed meat intake are associated with greater metabolic risk.

Targeted surveillance of 197 skin-lightening and skincare products purchased in New York City from 2009 to 2022 found detectable mercury in 29%, with 18% exceeding the FDA’s 1 ppm limit and concentrations reaching 27,000 ppm. All mercury-positive products were manufactured abroad, mercury was rarely disclosed on labels, and the findings highlight regulatory, health-equity, and environmental justice concerns.

The number of Australian women receiving intravenous iron treatments has surged dramatically over the past decade, with new research revealing that one in 20 women of reproductive age received intravenous iron in 2024.

Deep learning applied to more than 25,000 histopathology slides revealed tissue-specific structural signatures of biological aging that tracked telomere attrition, pathology, comorbidity, and molecular changes more closely than chronological age alone.

Culinary doses of herbs and spices did not significantly alter postprandial endothelial function, glycemia, or lipemia after four weeks of corresponding spice-containing diets in adults at cardiometabolic risk. The findings suggest that acute spice-related effects may be less apparent with longer-term exposure, although the study may have been underpowered to detect modest benefits.

For patients facing a diagnosis of glioblastoma - one of the most aggressive and devastating forms of brain cancer - the standard path forward has long meant an invasive open-skull surgery and a daunting prognosis.

Even for the same brain tumor treated with the same anticancer drug, the effect can differ from patient to patient.

People living with severe mental illness face a substantially higher risk of dementia throughout adulthood, as well as a significantly elevated risk of stroke in early and middle adulthood, according to a large new study based on health records from Catalonia, Spain.

Tuberculosis (TB) is responsible for about a quarter of all AIDS deaths. In 2024, it was also the leading cause of death among people with HIV. This is despite TB being a preventable and curable disease.

A UK-wide analysis of Drinkaware surveys found that suspected drink spiking and needling are widely underreported, with only 7% of affected 2022 respondents reporting the incident to the police. The findings also reveal gaps in public awareness, demographic differences in reported experiences, and psychological and physical effects that some respondents said persisted for decades.

AI-generated food images matched real food images in perceived healthiness and estimated calorie content but were rated as less realistic and elicited lower willingness to eat. A subset of hyperrealistic AI images received stronger appetitive ratings, suggesting that perceived realism may shape how synthetic food imagery is evaluated.

Tick-borne diseases are on the rise in the United States. Lyme disease is the most commonly reported, with nearly half a million people diagnosed each year.

Red blood cells serve as the foundation for nanocarriers that show promise in a new study as effective and efficient vehicles for gene therapy, tumor targeting and other medical treatments.

The complete genome for the tuberculosis bacterium was sequenced and published in 1998. Since then, scientists have deciphered about two-thirds of TB's genes. Or have they?

Experiencing trauma in childhood can lead to a lack of motivation and less pleasure from rewards-or anhedonia-later in life.

Of more than 500 occupations in the United States, flight attendants and pilots have the highest and second-highest proportion of radiation-related cancer deaths, a new study has found.

Approximately 65% of U.S. adults report consuming one or more sugar-sweetened beverages every day.

In humans and many other animals, a mother's age can affect the physical and behavioral characteristics of the next generation.
