Aging reshapes breast tissue creating environment favorable for cancer

Scientists have created the most detailed map to date, comprised of over 3 million cells, showing how breast tissue changes as women age – including dramatic changes during menopause.

Loving-kindness meditation links to lower anxiety through self-compassion

A new study suggests that loving-kindness and compassion meditation may be linked to lower anxiety over time, not just through longer practice, but also by building self-compassion and loosening the grip of distressing thoughts.

What happens when more of your exercise is vigorous instead of moderate?

In a large UK Biobank analysis, a higher proportion of vigorous physical activity relative to total activity volume was associated with lower risks of eight major chronic diseases and all-cause mortality, even after accounting for overall activity volume. Device-based data suggested that activity intensity generally offered greater preventive potential than total volume alone across most outcomes.

Innate immunity genes may influence earlier breast cancer onset in BRCA1 carriers

Damaging variants in genes involved in a rapid immune response (innate immunity) are significantly linked to earlier breast cancer onset in carriers of the harmful BRCA1 genetic mutation, reveal preliminary findings published online in the Journal of Medical Genetics.

Study reveals how extracellular matrix stiffness regulates breast cancer metastasis

A study by researchers at the University of California San Diego could make it easier to treat breast cancer by uncovering a new way the body helps prevent its spread.

Planetary health diet meets key nutrient needs during early pregnancy

Following The Planetary Health Diet in pregnancy can meet key nutrient requirements, suggesting that women who eat more sustainably in pregnancy may have higher intakes of several key-pregnancy-related nutrients, including folate, iron, calcium, and dietary fiber.

Why vaginal microbiota transplants aren’t working yet

Vaginal microbiota transplantation without antibiotics fails to restore microbiome balance, yet engraftment suggests avenues for enhancing treatment efficacy.

How video gaming may shape sleep, diet, and activity across the lifespan

This narrative review found that video gaming can have both benefits and risks for health across the lifespan. It may provide short-term stress relief and social connection, but frequent or prolonged gaming is also associated with sedentary behaviour, poorer sleep, disrupted eating patterns, and lower diet quality, with effects shaped by age, sex, timing, content, and motivation.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

How do diet, smoking, alcohol, and stress reshape the female microbiome?

This review examines how modifiable lifestyle and environmental factors shape the female vaginal, gut, oral, and skin microbiomes, with diet, alcohol, smoking, obesity, stress, hygiene, physical activity, and sexual behaviours all linked to site-specific microbial shifts. It argues that understanding these patterns could help guide future female-focused prevention and intervention strategies.

Study links atrial fibrillation to poorer brain clearance and cognitive decline

Researchers found that people with atrial fibrillation had lower MRI-based glymphatic activity and poorer cognitive performance than healthy controls, with the greatest impairment seen in non-paroxysmal AF. In patients who underwent catheter ablation, glymphatic activity improved after sinus rhythm was restored, suggesting a possible link between heart rhythm, brain waste clearance, and cognition.

Time-restricted eating improves hormone levels in women with PCOS

Polycystic ovary syndrome, or PCOS, affects as many as 18% of all childbearing-age women. The condition occurs when a woman's body produces too much of a group of hormones called androgens, chiefly testosterone. Menstrual irregularity, obesity and even infertility can result.

Probiotic therapy may offer a simple strategy to help prevent premature births

Preterm birth is a major cause of neonatal illness and death, especially among women with a history of premature delivery.

Chronic colitis reshapes colon stem cells in ways that can accelerate tumour growth

Researchers showed that chronic colitis leaves a long-lasting epigenetic memory in colonic stem cells, persisting for more than 100 days after recovery in mice. This memory is marked by durable AP-1-linked chromatin changes and later amplifies tumour outgrowth after oncogenic mutation.

APOE4 alters brain immunity and cognition differently in females and males

APOE4 drove sex-specific changes in meningeal immunity, lymphatic drainage, brain lipids, neuroinflammation, and cognition in mouse models, with females showing greater inflammatory and cognitive vulnerability. Suppressing innate immunity improved some cognitive outcomes in female E4/E4 mice but worsened them in male E4/E4 mice, underscoring the need for sex-tailored approaches.

$Heart health linked to higher fracture risk in postmenopausal women$

Heart health linked to higher fracture risk in postmenopausal women

Postmenopausal women face a high risk of bone fractures. Due to declines in estrogen levels, which can lead to an increased risk of osteoporosis, even a low-impact fall can result in a serious hip, back or wrist injury.

New mother’s experience highlights importance of postpartum heart care

At 35, Brooklyn resident Luyba Caloras was healthy, with no history of heart problems and no reason to think she was at risk of them. But pregnancy can act as a stress test on the heart—and soon after delivering her son at NYU Langone Health on February 3, 2024, she was diagnosed with a complication she never expected.

Study links diagnostic timing to ovarian cancer survival outcomes

The study "Diagnostic Timing and Ovarian Cancer Survival in North Carolina" has been published in the latest issue of JAMA Network Open. Led by a team of UNC-Chapel Hill researchers, this study explored the relationship between survival and how quickly patients are diagnosed with ovarian cancer.

Study reveals how a promising bacterial therapy reduces recurrent bacterial vaginosis

A new study from the Kwon Lab at the Ragon Institute, published in Cell Host & Microbe, provides the most detailed picture yet of how a promising bacterial therapy works to prevent recurrent bacterial vaginosis (BV) and why it works better for some women than others.

Global maternal deaths decline but progress slows worldwide

Global maternal deaths have declined over the past three decades, yet progress has slowed in recent years and remains uneven across countries, according to new Global Burden of Disease (GBD) 2023 research published today in The Lancet Obstetrics, Gynaecology, & Women's Health.
