Our bodies experience allergic reactions when the immune system mistakenly overreacts to harmless substances, known as allergens, such as pollen, dust, or certain foods.

Robot-assisted surgery (RAS) is one of the most advanced tools in modern medicine. These systems give surgeons extreme precision, allowing procedures to be performed through small incisions that minimize both pain and recovery time.

Chemotherapy remains a cornerstone of treatment for head and neck cancers, the seventh-most common cancer type worldwide.

Neuroblastoma is the most common solid tumor outside the brain in children younger than five years old and accounts for about 15% of pediatric cancer deaths.

The first evidence that night work and chronic insomnia may increase the risk of developing long COVID comes from a new study led by ISGlobal, a centre supported by "la Caixa" Foundation, in collaboration with the Germans Trias i Pujol Research Institute (IGTP), through the GCAT | Genomes for Life cohort.

Researchers have deciphered the role of an ion channel in iron homeostasis, opening up new possibilities for treating iron metabolism disorders.

Neck and back pain could be caused by changes in gene activity that trigger the breakdown of the spine's natural shock absorbers, new research suggests.

A new review article highlights a rapidly emerging frontier in oncology: the dynamic and influential relationship between nerves and tumors.

A secondary analysis of 7,067 nulliparous participants found that first-trimester protein intake of 0.8 to less than 1.1 g/kg/day was associated with 22% lower adjusted odds of delivering an SGA infant than intake of at least 1.1 g/kg/day. The association was exploratory, with no dose-response pattern and no confirmation in sensitivity analyses.

A new UC San Francisco study helps explain why people with HIV remain at elevated risk for type 2 diabetes despite effective suppression of the virus with modern medications.

A growing body of evidence is reshaping how cancer is understood, placing the spotlight on intra-tumoral microbiota as powerful yet previously overlooked players within the tumor microenvironment.

Researchers from the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have found that depression is associated with smaller volume in a specific part of the hippocampus, a brain region essential for learning and memory.

A study of nearly 100,000 adults treated for suspected infection suggests that the National Early Warning Score (NEWS2), a score based on routinely collected vital signs that is widely used to identify patients at risk of clinical deterioration, may help clinicians identify which patients are most likely to benefit from immediate antibiotic treatment and which may safely undergo further evaluation before receiving antibiotics.

Portable field surveillance reveals how untreated sewage is reshaping coastal microbial communities and spreading diverse resistance genes across one of the world’s most protected marine environments.

Preparation techniques used before embryo transfer, considered the most critical step in the IVF process, show no proven effect on pregnancy rates and remain inconclusive due to limited or low-quality data, a new Cochrane review finds.

The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain.

A web-based survey of 6,000 Japanese men aged 50 or older found that sexual arousal was the function they most wanted to preserve, while erection became more highly valued as erectile function worsened. Erection showed the earliest age-related decline pattern, whereas ejaculation was the function most often reported as lost in older age.

A newly published review highlights the pivotal role of FOXA2, a key transcription factor, in coordinating pancreatic development, maintaining islet cell identity, and regulating glucose homeostasis.

Having normal blood pressure, no diabetes, and not smoking from age 48 to 68, are associated with nearly 13 additional years on average of dementia-free life, a new study shows.
