Contraception and surgical sterilization associated with increased life expectancy

Blocking reproduction increases lifespan in both males and females of many different species, a new international University of Otago – Ōtākou Whakaihu Waka-led study has found.

Modern pollutants and ancient genetic variants could explain why some women develop endometriosis

A new study suggests that certain genetic differences, passed down from ancient human ancestors, and exposure to common present-day chemicals could explain why some women are more likely to develop endometriosis.

Early reversal of unhealthy weight can protect the heart from higher childhood BMI

Overweight as a child is not necessarily a risk factor for heart attack later in life. If weight is normalized before adulthood, the heart seems unaffected by the higher childhood BMI, according to a study conducted at the University of Gothenburg.

Psychosocial stress in women linked to early signs of heart tissue changes

Women who report high levels of psychosocial stress, such as from caregiving and lack of emotional support, show signs of early heart tissue changes associated with cardiovascular disease – an association not observed in men, a new study reveals.

Researchers capture high-resolution footage of flu viruses entering human cells

For the first time, researchers have observed live and in high resolution how influenza viruses infect living cells. This was possible thanks to a new microscopy technique, which could now help to develop antiviral therapies in a more targeted manner.

Daily tracking menstrual cycles show affects on athletes

New research reveals how daily tracking of menstrual and contraceptive symptoms impacts elite athletes' performance and well-being more accurately than surveys.

New study explores sweat's potential for real-time biomarker monitoring

Sweat contains a wealth of biological information that, with the help of artificial intelligence and next-generation sensors, could transform how we monitor our health and wellbeing, a new study suggests.

Study links endocrine-disrupting chemicals to hidradenitis suppurativa

A Johns Hopkins Medicine study involving a dozen people with the inflammatory skin disease hidradenitis suppurativa (HS), which mostly affects skin folds, is believed to be the first to provide evidence that hormone-disrupting chemicals commonly found in ultra-processed food and single-use water bottles may contribute to the development of or worsen the condition in some people.

Maternal thyroid hormone imbalance linked to increased autism risk in offspring

Women with persistent thyroid hormone imbalance across pregnancy may be at an increased risk of having children with autism, according to a new study published in The Journal of Clinical Endocrinology & Metabolism.

Study reveals metabolic benefits of reducing ultra-processed foods in older adults

A controlled feeding study out of South Dakota State University shows that older adults who ate fewer ultra-processed foods naturally consumed fewer calories, lost weight and abdominal fat, and showed improvements in insulin, nutrient-sensing hormones, and inflammation.

Ultraprocessed diets affect teens and young adults differently

A study reveals that adolescents consume more calories on ultraprocessed diets, highlighting a critical vulnerability in modern food environments.

Researchers identify the key habits that help adults eat more slowly

Eating slowly and chewing well in Japanese adults were strongly associated with savoring food and avoiding eating with a full mouth, with oral health playing an important supporting role. These behaviours varied across age and gender groups, highlighting cultural eating practices and dental factors that shape how people eat across adulthood.

Prenatal stress hormones may shape when a baby’s teeth erupt

A study links maternal stress hormones in late pregnancy to the timing of baby teeth eruption, highlighting prenatal factors in early childhood development.

Study shows how ketogenic eating improves hormonal balance in PCOS

The very low-carbohydrate ketogenic diet leads to meaningful reductions in weight, visceral adiposity, insulin resistance, and androgen excess in women with PCOS based on pooled randomized trials. Benefits appear consistent across studies, though high heterogeneity, short durations, and limited safety data highlight the need for longer-term comparative research.

Maternal stress linked to earlier baby teeth

Children have 20 milk teeth, 10 in each jaw. This set of teeth is important for chewing and speaking, and helps to keep space open for the subsequent set of 32 permanent teeth.

UCI Health launches clinical trial to test investigational cell therapy for lupus

UCI Health has opened a clinical trial to test an investigational cell therapy for lupus with the potential to give patients long-term remission of symptoms.

Study finds increased rates of DNA mutations in mice pups conceived with IVF

Mice pups conceived with in vitro fertilization (IVF) in the lab have slightly increased rates of DNA errors, or mutations, compared to pups conceived naturally, a new study on artificial reproductive technologies suggests.

High protein breakfasts help you feel fuller but do not change how much you eat later

High protein breakfasts, whether plant or animal-based, boosted GLP-1 and PYY and modestly reduced appetite compared with a low protein, high carbohydrate meal. Despite these hormonal and appetite changes, lunchtime energy intake remained unchanged in both younger and older adults.

New study reveals how the uterus senses force to drive labor

When labor begins, the uterus must coordinate rhythmic, well-timed contractions to deliver the baby safely.

Hormonal fluctuations shape learning through changes in dopamine signaling

Researchers have long established that hormones significantly affect the brain, creating changes in emotion, energy levels, and decision-making. However, the intricacies of these processes are not well understood.
