Bad habits such as smoking, heavy drinking and lack of exercise must be tackled as early as possible to boost the odds of a happy and healthy old age.

A study sheds light on when and how bacterial strains emerge on facial skin. The findings could lead to new treatments for acne and other conditions, and may also help optimize the timing of such treatments.

Breast cancer deaths among women ages 20-49 declined significantly between 2010 and 2020, according to a new study.

Childhood trauma significantly increases the likelihood of engaging in harmful alcohol consumption, smoking and illicit drug use, by the age of 18.

Results of a large, global clinical trial spanning five continents with over 1,700 patients with bronchiectasis has demonstrated benefits of an investigational, once-a-day pill called brenso catib as a therapy for the chronic lung condition. It may soon become the first-ever FDA-approved treatment for bronchiectasis.

A new study may offer reassuring news for parents whose children have a history of concussion, but want to get back to playing sports. Researchers spent more than a decade scouting fields, rinks and courts across the Greater Toronto Area for participants with a history of concussion and tested their performance on complex eye-hand coordination tasks, finding that age and previous sports experience were larger factors in cognitive-motor integration than a history of multiple concussions.

Depression in young teens could be easier to treat than in adulthood due to the symptoms being more flexible and not yet ingrained, a study shows.

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.

If you’ve been trying to quit vaping—or know someone who is—there’s big news: A new study found that teens and young adults who took a prescription pill called varenicline were more than three times as likely to stop vaping compared to those who just used counseling or a text support service. Varenicline is already FDA-approved to help adults quit smoking, but this study is the first to show how it could seriously help younger people quit vaping, too. Researchers say this is a big deal, especially since vaping is common among high schoolers.

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.
