Microglia are the most common immune cells in the brain, where they defend against intruders and engulf damaged neurons.

The ability to perform everyday activities free of debilitating symptoms profoundly affects quality of life as we age.

When you pick up a gallon of milk at the store, the nutrients it contains may depend on both what's on the label and the time of year.

Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green, or blue light.

Widely used Alzheimer’s biomarker P-tau 217 reliably detects the disease only at the clinical stage. The protein misfolding of amyloid beta indicates an increased risk years earlier.

Carterra®, a leading provider of high-throughput surface plasmon resonance (HT-SPR) platforms for antibody and small molecule discovery, today highlighted new research from Leerink Partners identifying Carterra as a key enabling technology in the fast-growing market for AI-driven biologics drug discovery.

Habit formation describes the repeated performance of a behavior until it becomes routine: in other words, the shift from deliberate to automatic decision-making.

A nationwide genomic epidemiology study involving a researcher from Kingston University has revealed that sexually transmitted Shigella sonnei is spreading faster, over greater geographic distances and with higher transmission intensity than non-sexually transmitted strains in England.

Many young adults may be entering adulthood without the practical skills needed to manage their own healthcare, suggests a new national poll.

Burnout is pushing emergency physicians to leave the specialty, or to reduce clinical hours, adding to the body of research pointing to a crisis in health care in Canada, according to a new study published in CMAJ.

Months to several years before amyotrophic lateral sclerosis (ALS) symptoms arise, levels of certain blood proteins may dramatically shift.

A scoping review on online oral health misinformation reveals gaps in evidence and highlights the impact of misleading content on patient behavior in dentistry.

Novogene Europe, a multiomics research services partner, today announced that it has expanded its single-cell RNA sequencing capability at its Cambridge Omics Centre.

Beckman Coulter Diagnostics, a Danaher company and a global leader in clinical diagnostics, today announced the U.S. launch of the DxU 1800 System, a fully automated urinalysis solution that combines a new chemistry analyzer and consumables with proven microscopy technology.

Tropical cyclone links to diarrheal disease varied widely across ten Asian regions, depending on how cyclone exposure was defined and whether mortality or morbidity was measured. Mortality associations were mostly uncertain, while morbidity patterns differed by region, with Taiwan showing the largest attributable burden.

Immune dysregulation may contribute to depression, schizophrenia, bipolar disorder, and anxiety through chronic inflammation, altered neuroimmune signaling, genetic susceptibility, and stress-related epigenetic changes. Evidence also suggests that biologically defined patient subgroups may benefit from more precise, immune-informed approaches to diagnosis and treatment.

Researchers analyzed 3,958 Korean-language medical YouTube videos and found that clickbait-heavy content attracted more views, likes, and comments. Higher-quality videos from medical professionals and public institutions often received less attention, highlighting a visibility gap in online health information.

Scientists have found the first direct evidence of the powerful role our genetic makeup plays in influencing our risk of cancer, with inherited genes interacting with acquired genetic mutations to shape how tumors evolve.

Porphyromonas gingivalis can evade antibiotics by invading host cells, contributing to recurrent periodontitis and persistent tissue damage.

Long-term wild bird surveillance across China revealed shifting H5Nx avian influenza patterns, with H5N1, H5N8, and clade 2.3.4.4b viruses changing over time and across migratory flyways. Genomic analyses suggest recent H5Nx detections in China largely reflect repeated reintroductions through migratory birds rather than sustained local circulation.
