Persistently high blood sugar and insulin resistance significantly increased the risk of worsening functional and structural heart damage during growth from adolescence to young adulthood, a new study shows.

The molecular mechanism behind why heart attacks can vary in severity depending on the time of day has been uncovered, potentially paving the way for innovative treatments that align with the natural circadian rhythm.

Body appreciation differs between Middle-Eastern and Western societies, a new international study can reveal, highlighting how cultural and family influences shape body image and eating behaviors in young women. The study surveyed over 850 women aged 18-25 in Australia and Lebanon, examining the roles that mothers and sisters play in shaping body dissatisfaction, body appreciation, and eating patterns.

Oral hormone therapy may benefit heart health in menopausal women. A new analysis of data from the Women's Health Initiative found that estrogen-based oral hormone therapy had a long-term beneficial effect on biomarkers of cardiovascular health, including cholesterol.

Adolescents who sleep for longer -- and from an earlier bedtime -- than their peers tend to have improved brain function and perform better at cognitive tests, researchers have shown. But the study of adolescents in the US also showed that even those with better sleeping habits were not reaching the amount of sleep recommended for their age group.

A new study found that the oral and extended-release injectable forms of naltrexone are equally effective in helping patients consume less alcohol, suggesting that clinicians should integrate this medication into routine hospital care.

Capitalizing on the flexibility of tiny cells inside the body's smallest blood vessels may be a powerful spinal cord repair strategy, new research suggests.

Breakthrough research could make any IV drug able to be taken orally for a range of hard-to-treat cancers and other diseases, and redefine how medicines are designed, evaluated and delivered.

A new study suggests that early-life exposure to two widespread environmental pollutants -- small particle air pollution and outdoor artificial light at night -- could increase the risk of pediatric thyroid cancer. The study found a 'significant association' between exposure to ambient fine particulate matter air pollution (PM2.5) and outdoor artificial light at night (O-ALAN) and increased risk of papillary thyroid cancer in children and young adults up to 19 years old. The exposures occurred during the perinatal stage of life, typically defined as the time from when pregnancy occurs up to a year after birth.

Researchers examined variations in the likelihood of older drivers causing traffic crashes based on the presence of a passenger, utilizing nationwide traffic crash data between 2014 and 2020. Their analysis revealed that even drivers with cognitive impairment had a reduced risk of causing crashes when accompanied by a passenger.

Among adults ages 18-49 (median age of 41 years) who were born with a hole in the upper chambers of their heart known as patent foramen ovale (PFO), strokes of unknown cause were more strongly associated with nontraditional risk factors, such as migraines, liver disease or cancer, rather than more typical factors such as high blood pressure.

Macaque mothers experience a short period of physical restlessness after the death of an infant, but do not show typical human signs of grief, such as lethargy and appetite loss, finds a new study by anthropologists.

A new study has found children born to mothers who experienced gestational diabetes (GDM) during pregnancy are more likely to develop attention-deficient hyperactive disorder (ADHD) and externalizing behavior.

Healthy sleep includes multiple components, such as number of hours of sleep per night, how long it takes to fall asleep, daytime functioning and self-reported sleep satisfaction, and addressing these different dimensions of sleep may help to reduce cardiometabolic health and related risk factors, according to a new scientific statement.

Proper nutrition is crucial for enhancing athletic performance, supporting recovery and overall health. Now, a new study reveals that proper nutrition is also key to reducing risk of injury, especially for females.

Risky driving by parents and other motorists who do the school run is putting children in danger, according to a new study.

Using eye-tracking -- a technique for recording and analyzing eye movements -- a team has shown that individuals with multiple disabilities can improve their social and emotional skills. Although these patients are often considered 'untestable', nine young people have undergone personalized training over a period of one year, with promising results in terms of their ability to socialize. This work opens the way to new methods of assessment and support.

Heavy drinkers who have eight or more alcoholic drinks per week have an increased risk of brain lesions called hyaline arteriolosclerosis, signs of brain injury that are associated with memory and thinking problems, according to a new study.

Researchers have found a new role for the transcription factor (proteins that regulate the transcription, or copying, of genes). In the fruit fly, this transcription factor, named Traffic Jam, activates a non-coding piRNA gene named Flamenco to promote female fruit fly (drosophila) fertility. The discovery solves the 30-year-old mystery of how Flamenco gets activated to protect fruit fly ovaries from a series of genetic parasites called retroviral transposons, and may one day help with infertility issues in humans.

Researchers explored the long-term effects of preschool expansion in Japan in the 1960s, revealing significant reductions in risky behaviors amongst teenagers. By analyzing regional differences in the rollout of the program, the study identified links between early childhood education and lower rates of juvenile violent arrests and teenage pregnancy. The findings suggest that improved noncognitive skills played a key role in mitigating risky behaviors, highlighting the lasting benefits of early-education policies.
