Researchers gained insights into how cells in the auditory system become organized to hear different frequencies. The findings could lead to new approaches for treating hearing loss.

A 3-D liver-inspired device made of hydrogel and nanoparticles can remove toxins from blood. The device provides a proof-of-concept model for new detoxification techniques.

Structured physical activity helped vulnerable older people maintain their mobility. The new study shows that moderate exercise might benefit even frail seniors.

Scientists have created the first living organism that can grow and reproduce using DNA base pairs that aren’t found in nature. The achievement is a major step toward creating novel therapeutics and nanomaterials.

People with a variant form of a lifespan-related gene also tend to have better cognitive skills than those who lack the variant, a new study reports—and helps to explain why.

A new treatment uses a patient’s own immune system to attack tumor cells. The approach might be used to treat many common cancers.

A long-term antimicrobial treatment can reduce the risk of recurrent urinary tract infection by up to 80% in children with the condition vesicoureteral reflux, a new study found.

A follow-up treatment for infants receiving surgery for a life-threatening liver disease doesn't bring significant clinical benefit and causes early side effects, according to new findings.

Scientists used human embryonic stem cells to regenerate damaged primate hearts. The strategy might one day be used to repair human hearts, but challenges still need to be overcome.

Mitochondria in muscle form networks, fuse, and share components. The findings give insight into muscle disorders and how alcohol use can lead to muscle weakness.

Enhancing brain mechanisms triggered by stress raised the resilience of mice to stress and relieved depression-like behaviors.

A drug used to treat glaucoma, combined with a weight loss plan, improved vision for women with a disorder called idiopathic intracranial hypertension.

Researchers determined how an abnormal gene begins the process that leads to neuron death and Parkinson’s disease. The finding hints at potential therapies for the movement disorder.

A diarrhea-causing parasite latches onto human cells and nibbles away at them until they die. The finding could lead to new ways to block the parasite.

Scientists identified areas of the brain that help us target our attention to objects, such as faces. The study offers insight into how we focus amid a barrage of distraction.

Hospitalized patients who had fewer blood transfusions had lower risks of infection, a study showed. More conservative transfusion strategies might reduce infection rates.

An experimental spinal stimulation therapy helped 4 young men who were paralyzed below the chest because of spinal cord injuries to regain control of some movement.

Two research teams revealed how cells in skin feel fine detail and texture. The findings could lead to new approaches to restore the sense of touch lost to aging and certain diseases.
