Researchers developed a novel method to turn off prion protein production in mice. The technique could lead to treatments for prion diseases such as mad cow disease.

In a family with an inherited form of Alzheimer’s disease, those who carried a gene variant called APOE3Ch had a delay in cognitive impairment and dementia. More research is needed to see whether APOE3Ch has a protective effect in people beyond this family and to understand how it exerts its protective effect.

Researchers found that an H5N1 flu virus from cows could infect mice and ferrets, but airborne transmission wasn’t very efficient.

This feature explores experimental approaches to allow people living with paralysis to become more independent and improve quality of life.

Higher blood levels of the artificial sweetener xylitol were associated with increased risk of heart attack and stroke in people.

Scientists developed an AI tool that uses routine clinical data to identify cancer patients most likely to respond to immunotherapy drugs called checkpoint inhibitors.

A five-minute, culturally neutral test for cognitive problems improved dementia detection and management in older adults.

Researchers created massive, advanced maps of the complex networks that regulate gene function in the brains of people with and without mental disorders.

Children who regularly ate peanut-containing foods early in life had a greatly reduced risk of developing peanut allergy into adolescence.

Scientists created a compound that causes reversible contraception in male mice.

H5N1 avian flu virus survived in raw dairy milk kept under refrigerated conditions for at least five weeks.

In the largest study of its kind, researchers identified genetic variants that appear to boost breast cancer risk among females of African ancestry.

Researchers traced differences in parental care between two mouse species to a new cell type in the adrenal glands.

The prevalence of cognitive impairment among older American Indians may be higher than previously thought, according to a new analysis.

Researchers found that brief bouts of anger can impair the ability of blood vessels to expand and contract, which might have consequences for heart health.

In a study of people primarily of European descent, those with two copies of a certain gene, APOE4, predictably began to develop the underlying abnormalities of Alzheimer’s disease as early as age 55.

A study of endurance training in rats found molecular changes throughout the body that could help explain the beneficial effects of exercise on health.

A single dose of a monoclonal antibody given to children 6 to 10 years of age in Mali proved up to 77% effective at preventing malaria disease.
