Researchers developed an approach that can predict preeclampsia in pregnant women as early as the first trimester by using cell-free DNA in blood samples.

Researchers designed a gene-editing system that replaced up to a quarter of the main type of cell in the mouse liver with edited cells.

Researchers constructed a map of molecular and cellular changes in marmoset brains that occur in developing lesions like those in multiple sclerosis (MS).

Researchers developed a way to track what people ate by analyzing DNA from stool samples.

Researchers found that infectious bacteria in diabetic mice rapidly evolved resistance to antibiotics.

Scientists found that, when deprived of amino acids, cancer cells cooperated to extract and share them from their environment.

Peanut-allergic children who could tolerate eating at least a half peanut greatly boosted their tolerance by eating gradually increased daily doses of peanut butter.

Tiny electrodes placed precisely in the brain let people with spinal cord injuries feel sensations of shape, motion, and the orientation of objects on the skin.

Researchers found how scratching can worsen allergic skin symptoms but also protect from infection.

Researchers estimated that 42% of Americans over age 55 will eventually develop dementia.

Researchers identified antibodies that bind to a previously untargeted portion of the malaria parasite.

Researchers have made huge strides in learning how to detect signs of cancer in bodily fluids like blood, saliva, and urine. Learn how these liquid biopsies are being tested to aid early cancer detection and guide treatment.
