A study in mice showed how that a mother's gut bacteria can induce antibodies that protect newborns against diarrheal disease.

An analysis of U.S. death certificate data showed that alcohol-related deaths increased among people in almost all age and racial and ethnic groups between 1999 and 2017.

A study suggested that PET imaging of tau tangles in the brain could be a way to track development of Alzheimer's disease, predict loss of brain tissue, and assess new treatments.

A laboratory study gave new insight into how skin creams, cosmetics, and fragrances may cause immune responses that lead to rashes in some people.

People with higher exposures to common insecticides called pyrethroids had an increased risk of death in the years following the measurements.

Delivering the only approved tuberculosis vaccine intravenously greatly enhanced its ability to protect rhesus monkeys from infection.

Researchers found that mutations in a specific gene cause a previously unknown autoinflammatory disease, which they’ve named CRIA syndrome.

Blood levels of around 400 proteins accurately reflected people’s age and relative health. Such a protein signature might help identify people at greater risk of age-related diseases.

Scientists found that some immune cells in people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) show disruptions in the way they produce and use energy.

Noteworthy NIH advances in basic research include evidence linking enterovirus infections with acute flaccid myelitis, insights into how disrupted sleep may lead to heart disease, and nanoparticle robots that sweep away biofilms.

NIH findings with potential for enhancing human health include a way to predict which people at risk for psychosis may progress to full psychosis, insights into recurrent tonsillitis, and a patch to replace damaged retinal cells.

NIH accomplishments in disease prevention, diagnosis, and treatment include treatments for the Ebola virus, gene therapy that reverses a rare immune disorder, and a blood test to detect myalgic encephalomyelitis/chronic fatigue syndrome

Researchers found a unique population of stem cells in the roof of the mouth that quickly respond to stress from chewing and injury.

Three commonly prescribed anti-seizure drugs worked equally well for seizures in patients with a severe form of epilepsy called refractory status epilepticus who didn’t respond to benzodiazepines.

Two experimental drugs each reduced the risk of death from Ebola when tested in an outbreak in the Democratic Republic of Congo.

A rare form of skin cancer may sometimes start with cancer-causing mutations in hair follicle stem cells.

A therapy targeting bacteria that make a specific toxin lessened alcohol-associated liver disease in a mouse study.

In a mouse model of Down syndrome, blocking a cellular pathway in brain cells improved learning and memory.

A study found that about 17% of children with food allergies are also allergic to sesame, highlighting the importance of using caution when exposing these children to sesame.

Mice fed a very high-salt diet showed accumulation of a protein in the brain linked with Alzheimer’s disease and other dementias.

A study found that people experienced less pain when the treatment provider expected the pain reliever to work.

Researchers identified three antibodies that protect against multiple strains of influenza virus by targeting the surface protein neuraminidase. The findings could help researchers develop better flu vaccines and treatments.
