Infectious disease researchers have identified Pteropine orthoreoviruses (PRVs), a group of newly emergent bat-borne viruses, as the culprit for previously unexplained illness in five Bangladeshi patients, one of whom eventually died with unexplained illness.

This global macroeconomic analysis estimates that diabetes mellitus will cost the world economy INT$10.2 trillion between 2020 and 2050, rising to INT$78.8 trillion when unpaid informal caregiving is included. Using a health-augmented economic model across 204 countries, the study shows that informal care is the dominant and most underestimated driver of diabetes-related economic losses worldwide.

Dorota Skowronska-Krawczyk sits in her office, eyes fixed on the computer monitor in front of her.

Anorexia nervosa is a psychiatric condition characterized by a fear of weight gain and reduced calorie consumption that can result in dangerous weight loss.

Decades of research show that early psychosocial stress, including chronic exposure to adversity, can shape how a child's brain develops, with effects that last well beyond childhood. But families rarely experience just one source of stress at a time.

This population-based study shows that shared and pattern-specific blood biomarkers reflect biological vulnerability underlying multimorbidity and the pace at which chronic diseases accumulate in older adults. Metabolic and systemic stress markers such as GDF15, HbA1c, cystatin C, and insulin consistently tracked higher disease burden and faster accumulation, with findings replicated across cohorts.

Low back pain (LBP) is a prevalent condition associated with disability, work loss and economic burden to healthcare. Significant risk factors include poor sleep, physical and psychological stress, inactivity, advanced age and smoking.

Immune checkpoint molecules play a crucial role in keeping the immune system in balance and preventing an attack on the body's own cells.

More than half of the world's population speaks more than one language-but there is no consistent method for defining "bilingual" or "multilingual." This makes it difficult to accurately assess proficiency across multiple languages and to describe language backgrounds accurately.

Globally, RSV causes millions of respiratory infections each year and is responsible for a large proportion of hospitalizations and deaths among children under five years, with the highest risk concentrated in infants under six months.

An international research team identified hundreds of genes essential for the development of brain cells, including one gene linked to a severe neurodevelopmental disorder not previously described.

New study reveals that bacteria can survive antibiotic treatment through two fundamentally different "shutdown modes," not just the classic idea of dormancy.

Self-harming and self-sabotaging behaviors, from skin picking to ghosting people, all stem from evolutionary survival mechanisms, according to a compelling new psychological analysis.

For the first time, scientists have reconstructed ancient genomes of Human betaherpesvirus 6A and 6B (HHV-6A/B) from archaeological human remains more than two millennia old.

Circadian rhythms that are weaker and more fragmented are linked to an increased risk of dementia, according to a new study published on December 29, 2025, in Neurology®, the medical journal of the American Academy of Neurology.

Placenta accreta spectrum (PAS) used to be a rare pregnancy condition, but it now affects roughly 14,000 pregnancies annually, posing a major cause of maternal death.

A new University of Toronto-led study has discovered a possible biomarker linked to multiple sclerosis (MS) disease progression that could help identify patients most likely to benefit from new drugs.

As cesarean delivery (C-section) rates continue to rise worldwide, experts at NYU Langone Health are highlighting a surgical technique that may help lower the risk of long-term complications.

In a new study, Christine Agdestein has surveyed several aspects of the postnatal check-up. Agdestein is a specialist in general practice and a general practitioner, and is currently a PhD candidate at the Norwegian University of Science and Technology (NTNU).

When food prices skyrocket during an economic crisis, it is primarily urban populations and people with low levels of education who are affected.
