Researchers uncover how surrounding cells fuel triple-negative breast cancer growth

Triple-negative breast cancer, which accounts for approximately 10–15% of all breast cancer cases, is considered particularly difficult to treat because it grows rapidly and carries a high risk of recurrence.

Researchers identify promising new immune target for treating endometriosis

Affecting 200 million women of reproductive age, endometriosis is a chronic inflammatory disease that causes pain, infertility, and increased ovarian cancer risk.

Yale Cancer Center offers team-based care for breast cancer patients

Hilary Axtmayer can pinpoint the moment her life changed. In 2023, Axtmayer-then a 40-year-old mother of two from Madison, Conn.-was receiving her regularly scheduled breast exam when her gynecologist paused mid-palpation. She'd found a lump.

Proton therapy radiation patterns may increase breast implant complications

Radiation therapy is sometimes needed after mastectomy and breast reconstruction for breast cancer.

Yogurt and cheese are rich in protein, but do they help aging muscles?

In a cross-sectional analysis of 6,790 adults aged 50 and older across two Irish cohorts, researchers found no consistent association between fermented dairy consumption and muscle strength, physical function, or frailty after accounting for lifestyle and socioeconomic factors. Although one analysis linked higher fermented dairy intake to greater odds of low grip strength, other findings did not support this association, and the researchers emphasized the need for further studies to establish whether fermented dairy influences healthy muscle aging.

‘Forever chemicals’ linked to slightly lower muscle mass in middle-aged women

A study of 551 middle-aged women found that higher blood concentrations of certain PFAS chemicals were associated with slightly lower muscle mass, particularly when researchers examined multiple chemicals together. However, these associations did not correspond to poorer muscle function, and the largely cross-sectional findings could not establish whether PFAS exposure contributes to muscle loss.

Exercise benefits mental health, so why is the genetic evidence so mixed?

A systematic review of 61 Mendelian randomization studies found limited and inconsistent genetic evidence that general physical activity causally improves mental health or cognitive outcomes; 30 studies reported only null or directionally opposite findings. More consistent evidence emerged for aerobic exercise and reduced depression risk, and for physical fitness traits, particularly muscle strength and muscle mass, in relation to better mental and cognitive health, although methodological limitations prevent definitive causal conclusions.

The way food feels in your mouth could change how much you eat

A scientific review examines how food texture and mouthfeel interact with oral sensory receptors, saliva, and brain pathways to influence food preferences, eating speed, appetite, and fullness. The authors suggest that understanding these mechanisms could help develop healthier, more satisfying foods, although their long-term effects on metabolic health require further investigation.

Exercise benefits people with chronic disease, but does the type matter?

A meta-analysis of 48 studies found that physical activity improved several chronic disease-related health indicators, particularly blood pressure, heart rate, and cardiorespiratory fitness, with significant benefits among people with hypertension and diabetes. Aerobic exercise had the strongest statistical evidence in the primary analysis, but no exercise type proved superior, and substantial variation between studies limited the certainty of the findings.

Ice massage, massage guns or rest? Runners tried three ways to recover

In a randomized trial of 80 recreational runners, repeated ice massage, percussive massage, and combined treatment improved reactive strength, reduced muscle soreness, and produced greater reductions in calf and Achilles tendon stiffness over 72 hours than passive rest. Combined treatment produced the largest improvement in reactive strength, although its advantage over individual treatments was based on exploratory comparisons, and none of the interventions showed a sustained benefit for the biochemical marker LDH.

Prenatal cannabis use disorder linked to higher postpartum psychiatric emergency visits

Women diagnosed with cannabis use disorder during pregnancy were more likely to end up in an emergency room for a psychiatric problem in the year after giving birth, according to a study of more than 2 million California deliveries.

Breakthrough RNA blood test identifies hidden ovarian cancer warning signs

Hoag researchers announced a first in the world discovery of a molecular warning signal in the blood that identifies serous tubal intraepithelial carcinoma (STIC), an early, precancerous stage of high-grade serous ovarian cancer (HGSOC).

Chemotherapy may accelerate biological aging in breast cancer survivors

Chemotherapy helps many women survive breast cancer, but new research suggests that chemotherapy may also accelerate biological aging beyond chronological age and increase the risk of earlier death from other causes.

PMDD symptoms follow three distinct patterns, study finds

Premenstrual dysphoric disorder (PMDD) is a common mood disorder associated with the menstrual cycle. A new study published in Nature Communications shows that PMDD does not follow any universal pattern, and that there are three subtypes with different patterns of symptoms.

Not all narcissism is alike. A study of 1,524 students reveals why that matters

Two studies involving 1,524 German university students found that narcissistic rivalry was associated with poorer psychological well-being, greater self-doubt, and lower academic satisfaction, while narcissistic admiration was associated with higher life satisfaction and better mood. Admiration also showed selective positive associations with academic satisfaction, particularly study content, although the cross-sectional findings cannot establish cause and effect.

Scientists scanned people's brains before and after 45 days of yoga. Here's what changed

In a randomized controlled trial involving 139 healthy adults, 45 days of a standardized yoga program improved mood, self-reported sleep quality, and selected short-term memory measures compared with a waitlist control group. Brain scans from 43 participants also revealed changes in functional connectivity across networks involved in movement, attention, language, and cognitive processing, although the long-term significance remains uncertain

Eating too much ultra-processed food? A study links it to worse PMS symptoms

A cross-sectional study of 607 young adult women in Turkey found that higher ultra-processed food consumption scores were associated with more severe premenstrual syndrome (PMS) symptoms, while non-judgmental and non-reactive mindful eating behaviors were linked to lower symptom severity. Mediterranean diet adherence was not independently associated with PMS severity, and the researchers cautioned that the findings cannot establish cause and effect.

Could eating more mushrooms help protect your brain as you age?

A review of existing research suggests that ergothioneine, a natural antioxidant found primarily in mushrooms, may protect brain cells against oxidative stress, inflammation, and damage associated with Alzheimer's and Parkinson's diseases. Although laboratory and animal studies show promising neuroprotective effects, human evidence remains limited, and larger clinical trials are needed to determine whether supplementation can prevent or slow neurodegeneration.

Artery scans detect “silent atherosclerosis” in 1 in 13 adults under 30

Researchers studying 16,808 adults aged 18 to 70 found that silent atherosclerosis was detectable in early adulthood, with plaque present in 57.1% of those who completed imaging across three arterial territories. Plaque prevalence and burden were higher in older age groups, with men showing earlier evidence of disease than women, while conventional cardiovascular risk scores identified relatively few people with existing plaque.

Your Instagram photos may reveal more about loneliness than you think

Researchers analyzing Instagram data from 415 US college students found that photographs, language, and online activity provided moderately useful indicators of subjective loneliness but were less informative about social isolation. Social loneliness was associated with lower interpersonal engagement, while emotional loneliness was linked to negative language, sad or angry facial expressions in profile photographs, and late-night posting.
