Researchers show stem-like T cells within certain lymph nodes could be natural cancer fighters.

Research has discovered that the strength of the connection between our brain and internal organs is linked to how we feel about our appearance. The study has investigated the association between body image and the brain's processing of internal signals that occur unconsciously. It found that adults whose brains are less efficient at detecting these internal messages are more likely to experience body shame and weight preoccupation.

A next-generation brain implant currently in clinical use for treating refractory epilepsy -- to help prevent symptoms including seizures -- does not induce changes to patients' personalities or self-perceptions, a new study of patient experiences shows.

It has been a mystery why some people live a perfectly normal life until experiencing a potentially deadly cardiac episode. Now, researchers present a possible explanation in a microscopic modification of a protein, which causes a mutation to turn harmful. The knowledge could help future diagnosis and drug regimens.

A study of a geographically, clinically, and socioeconomically diverse, nationally-representative sample of US households -- including both adult patients and caregivers of children with food allergy -- found that 72 percent did not know what oral immunotherapy (OIT) was prior to the survey. Researchers also discovered that current OIT awareness is disproportionately elevated among wealthier, more highly educated respondents, which underscores the need for more equitable outreach efforts and greater access to these therapies for all patients with food allergies.

Vaccinations against human papillomavirus (HPV), a major cause of throat and back of mouth cancers, are expected to yield significant reductions in the rates of these cancers in the U.S., but will not do so until after 2045, according to a new modeling study.

Parents and educators have long fretted over the amount of time children and teenagers spend online. But when it comes to screen time, the problem is not so much the number of hours spent online, but the quality of online interactions, particularly under stringent COVID-19 distancing or lockdown conditions, a new study shows.

Rhesus macaques naturally exposed to wildfire smoke early in pregnancy had an increased rate of miscarriage, according to new research.

An analysis of more than 20,000 individual medical records suggests that a form of heart valve disease thought to be relatively benign during pregnancy may put women at risk for serious bleeding, high blood pressure, organ damage and other complications during childbirth.

Cancer research experts report on discovering a rare population of cells that help create a polluted bone marrow environment that in turn allows other mutated cells to trigger MDS.

Brain regulation of feeding behavior traits has remained incompletely understood. In a new study, researchers discovered a connection between the function of the opioid system and food craving triggered by appetitive external stimuli.

Researchers have a new lens by which to understand how genes impact disease.

Researchers successfully developed and validated a new outcome measure to monitor disease severity and progression in patients with impaired skeletal muscle function caused by mitochondrial disease. This measure, named 'Mitochondrial Myopathy-Composite Assessment Tool' ('MM-COAST'), is important to identify specific skeletal muscle and neurological problems in both children and adults with mitochondrial disease and may be used to measure response to treatment interventions in future clinical trials.

A study has established a new resource for exploring and understanding Alzheimer's disease (AD) on an individualized level.

A study finds a heightened risk of death from medical causes for infants with histories of reported maltreatment, suggesting a need for ongoing care coordination between the child protection system and pediatric health providers.
