A sweeping scientific review highlights wild blueberries as a standout food for cardiometabolic health. The strongest evidence shows improvements in blood vessel function, with encouraging signs for blood pressure, cholesterol, blood sugar, gut ...

A common parasite long thought to lie dormant is actually much more active and complex. Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, .. ...

Researchers have discovered a biological switch that explains why movement keeps bones strong. The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting .. ...

Asthma may not be driven by the molecules scientists have blamed for decades. Researchers have identified "pseudo leukotrienes," inflammation-triggering compounds formed by uncontrolled free-radical reactions rather than normal enzymes. These ...

A long-term study found that while a ketogenic diet prevented weight gain, it also triggered major metabolic problems. Mice developed fatty liver disease, abnormal blood fats, and an impaired ability to control blood sugar--especially after ...

Findings could create new opportunities to treat and study neurodegenerative diseasesScientists discovered that sugar metabolism plays a surprising role in whether injured neurons collapse or cling to life. By activating internal protective programs, ...

A large French study tracking more than 100,000 people over a decade has found that higher consumption of certain food preservatives--commonly found in processed foods and drinks--is linked to a modestly higher cancer risk. While many preservatives . ...

Carbohydrates don't just fuel the body--they may also influence how the brain ages. A large long-term study found that diets high in fast-acting carbs that rapidly raise blood sugar were linked to a higher risk of dementia. People who ate more low .. ...

A new genetic study suggests that obesity and high blood pressure may play a direct role in causing dementia, not just increasing the risk. By analyzing data from large populations in Denmark and the U.K., researchers found strong evidence that ...

Home fireplaces and wood stoves are quietly driving a large share of winter air pollution, even though only a small number of households rely on wood heat. Researchers found that wood smoke accounts for over one-fifth of Americans' winter exposure to ...
