Scientists have found out exactly how an exercise-triggered molecule suppresses hunger signals in the brain, leading to weight loss. It could be harnessed as a therapeutic, providing the same benefit without the work it takes to produce it naturally.

A simple haircut may reveal more than just split ends. By testing for the stress hormone cortisol, which is stored in hair, researchers can identify kids with chronic illness who face the greatest risk of anxiety, depression, or behavioral struggles.

In a massive study, scientists have failed to find any meaningful link between the use of opioid painkillers and the prevalence of autism spectrum disorder and attention-deficit/hyperactivity disorder, challenging earlier research suggesting otherwise.

A new study shows that a personalized, precise form of brain stimulation, HD-tDCS, can rapidly ease depression symptoms – and even reduce anxiety – offering a promising drug-free alternative with only mild side effects.

A new breakthrough removes the dangers involved in a process called STING, in which the body's own immune system can be enlisted to fight cancer. The finding clears the way for a powerful, and safe, weapon against tumors.

The US Food and Drug Administration (FDA) has approved the first intranasal diuretic for heart, liver and kidney disease patients, aiming to prevent a common and costly issue that results in more than a million hospitalizations each year.

Heart attacks in younger adults aren’t always due to clogged arteries. A new major study reveals striking differences between men and women, with nontraditional causes playing a big role in women’s heart health.

It's common knowledge that avoiding too much sugar or acid-containing foods is a good way to keep your oral health on the right track. But a new study now reveals that a common well-regarded eating plan can also have a big positive impact.

In a massive study of more than nine million pregnancies, a strong link has been found between gestational diabetes and children born with neurodevelopmental conditions – it translates to a 36% increased risk of ADHD and a 56% higher risk of autism.

Strong bones need more than workouts; they need less sitting. A sweeping review shows that across all ages, even light daily activity protects bone health, while too much sedentary time quietly raises the risk of fractures.

Healthy eating doesn’t just shrink your waistline; it can ease chronic pain. A new study shows that better diet quality reduced pain severity and improved quality of life, independent of weight loss.

Your morning coffee might do more than wake you up – it could weaken donated blood. A large new study shows caffeine lowers red blood cell quality, making transfusions less effective, especially in patients who need them most.

Researchers have uncovered a gut-diet link to postpartum depression, finding that eating a diet of soy, fermented foods, and seaweed may nurture beneficial gut bacteria and protect mothers’ mental health.

When scientists study obesity, it's often focused on genetics, physical activity and poor eating habits. However, new findings show that stress, hardship, isolation and social inequality create the biological environment that underpins the epidemic.

Signs of immune system aging appear years before rheumatoid arthritis takes hold, offering new hope for early diagnosis and treatments that could slow or stop the disease before it starts, according to new research.
