Can this medication reverse MS? Brain biomarker shows it can

A decade after scientists identified an over-the-counter antihistamine as a treatment for multiple sclerosis, researchers have developed an approach to measure the drug’s effectiveness in repairing the brain, making it possible to also assess future th…

Researchers uncover why light-to-moderate drinking is tied to better heart health

A new study offers an explanation for why light-to-moderate alcohol consumption may be associated with lower risk of heart disease. For the first time, researchers found that alcohol, in light to moderate quantities, was associated with long-term reduc…

Mouse models of adolescent binge drinking reveal key long-lasting brain changes

Heavy alcohol consumption may cause permanent dysregulation of neurons, or brain cells, in adolescents, according to a new study in mice. The findings suggest that exposure to binge-levels of alcohol during adolescence, when the brain is still developi…

New research identifies cells linking chronic psychological stress to inflammatory bowel disease

For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals fr…

How chronic stress drives the brain to crave comfort food

Stress can override natural satiety cues to drive more food intake and boost cravings for sweets.

Long missions, frequent travel take a toll on astronauts’ brains

A study looking at how the human brain reacts to traveling outside Earth’s gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.

A chance observation finds potential hearing biomarker for Alzheimer’s disease

Researchers found where plaques are found in the brain may impact hearing in Alzheimer’s disease.

Poorly insulated nerve cells promote Alzheimer’s disease in old age

Researchers have shown that defective myelin actively promotes disease-related changes in Alzheimer’s disease.

How caregiver speech shapes infant brain

New research shines light on how parents who talk more to their infants improve their children’s brain development. Scientists used imaging and audio recordings to link early language skills to caregiver speech, delivering an affirming message that par…

Newly discovered brain mechanism linked to anxiety, OCD

The pandemic and its aftermath have raised anxiety to new levels. But the roots of anxiety-related conditions, including obsessive-compulsive spectrum disorder (OCSD), are still unclear. In a new study, scientists discovered insights into the importanc…
