Exercise can have benefits at the level of neurons, through chemical and mechanical effects, MIT researchers find. The discovery could inform exercise-related therapies for repairing damaged and deteriorating nerves.

Researchers have developed a promising nasal spray therapy targeting neuroinflammation in Alzheimer’s disease, potentially delaying its progression by over a decade.

A bottle of water can contain a quarter of a million pieces of plastic, a study has found. Scientists have found a new category of plastic pollution called nanoparticles, which are created when microplastics break down even further. It had previously been impossible to tell how many particles smaller than one micron, one seventieth of the width of ...

A growing body of research shows that exposure to air pollution, especially during pregnancy and childhood, may have a negative impact on brain development. Now a study led by the Barcelona Institute for Global Health (ISGlobal) has found that exposure to nitrogen dioxide (NO2) during the first two years of life is associated with poorer attention capacity in children aged 4 to 8, especially in boys. NO2 is a pollutant that comes mainly from...

If you come across brightly colored, cloth-bound books from the Victorian era, you might want to handle them gently, or even steer clear altogether. Some of their attractive hues come from dyes that could pose a health risk to readers, collectors or librarians.

Using non-invasive techniques to manipulate our emotions, it might be possible to curtail the screaming horrors that plague our sleep. A study conducted on 36 patients diagnosed with a nightmare disorder showed that a combination of two simple therapies reduced the frequency of their bad dreams. Scientists invited the volunteers to rewrite their most frequent nightmares in a positive light and then played sound associated with positive experienc

Recent research indicates that mRNA Covid-19 vaccines may not generate long-lasting immune protection.

Physical, sexual, or emotional abuse, or neglect, either alone or combined with other types of childhood trauma, increases the risk of chronic pain and related disability in adulthood, according to new research.

A new study indicates what researchers describe as an ongoing "stubborn mistrust" in science among the American public as it relates to COVID-19 vaccines.

Childhood trauma can raise the risk of developing major diseases later in life that vary based on a person's unique experiences and even their sex, new research concludes. Why it matters: Although it's widely understood that trauma early in life has biological and real-world health impacts, the findings shed light on how different life experiences can shape the way the body functions and make a person susceptible to chronic diseases....

Exposure to higher levels of light can help people feel more awake and increase cognitive performance, probably by influencing the activity of parts of a brain region called the hypothalamus, according to new research.

Cardiovascular disease is a leading cause of death worldwide. One major contributor is the buildup...

Archaeologists say tobacco consumption leaves a metabolic record that can be studied for centuries

Our species is especially vulnerable.
