A major multi-country study has found that WHO-recommended first-line antibiotics for neonatal sepsis are likely to be effective in only one quarter of infections in low- and middle-income countries (LMICs).

Scientists from Johns Hopkins Medicine report new evidence that clusters of brain tissue derived from the cells of patients with Alzheimer's disease may be used to evaluate how certain patients with the neurodegenerative condition may respond to drugs commonly prescribed to treat psychiatric symptoms of the disorder.

The same neurotransmitter commonly leveraged to relieve symptoms of depression and anxiety also may exacerbate a vexing condition known as tinnitus, according to new research published in the Proceedings of the National Academy of Sciences.

A large NIH-funded RECOVER-Pediatrics study found that children and adolescents meeting the long COVID research threshold were more likely to have caregiver-reported worsening grades, attention difficulties, reduced enjoyment with friends, and greater IEP involvement than peers below the threshold. The findings suggest that pediatric long COVID may affect school and social functioning during key developmental years, although the cross-sectional design does not establish causation.

Researchers from the Keck School of Medicine of USC have made an important advance toward understanding-and potentially treating-a rare cardiomyopathy (heart muscle disease) that is present from birth.

While some say having lots of kids can make you lose your faculties, a new study suggests otherwise.

Tumor-associated macrophages (TAMs) within the tumor microenvironment (TME) exhibit significant metabolic dysregulation, which impairs their antitumor function.

Analysis of microbes in the gut can reveal whether a person faces an elevated risk of Parkinson's disease, before they have developed any symptoms, suggests a new study led by University College London (UCL) researchers.

Nestlé and NTU Singapore today announced a multi‑year joint research partnership to advance the scientific understanding of how nutrition supports healthy longevity and women's health.

Acute sinusitis leads to more antibiotic prescriptions for U.S. adults than any other condition, but there is no consensus on which antibiotic is preferred for uncomplicated cases.

A landmark trial presented today at ESCMID Global 2026 shows that improving oral hygiene for hospital patients can reduce the risk of non-ventilator-associated hospital-acquired pneumonia (NV-HAP) by 60%.

Researchers at Linköping University show how two important cancer-related proteins can be prevented from collaborating with each other.

This study found that pertussis cases fell across Japan, Australia, New Zealand, China, and the USA during COVID-19 restrictions, then resurged afterward, with most countries peaking in 2024 but Japan showing a delayed major outbreak in 2025. In Japan, the surge was concentrated in school-aged children and adolescents, highlighting possible gaps in booster protection and the need to reassess immunization strategies.

A Neuropsychopharmacology Circumspectives article argues that cannabidiol has genuine therapeutic potential, especially in treatment-resistant pediatric epilepsy, but evidence for most other uses remains limited, heterogeneous, and not yet mature enough for broad clinical adoption. The authors also warn that poor retail product quality, inaccurate labeling, contaminants, hepatotoxicity risk, and drug interactions are major barriers to safe and effective real-world use.

Researchers analyzed more than 500,000 de-identified Microsoft Copilot health conversations from January 2026 and found that health information queries were most common, while nearly one in five conversations involved personal symptoms or condition-related concerns. They also found that personal health queries were more common on mobile and at night, while desktop use was more often tied to research, paperwork, and academic support, highlighting how people use AI differently across contexts.

A landmark study led by researchers at the University of Nebraska Medical Center (UNMC) and published in Molecular Psychiatry has identified a significant association between prenatal prescription of commonly utilized medications and the risk of autism spectrum disorder (ASD) in children.

Understanding which cells within a tumor will go on to form metastases remains one of the major challenges in cancer research.

Up to 80% of people who receive chemotherapy experience cancer-related cognitive impairment, which most commonly involves mild-to-moderate changes such as difficulty paying attention, memory lapses, and struggles with multitasking.

Antibiotic resistance genes (ARGs) – segments of DNA that help bacteria survive the effects of antibiotics – can be present in newborns within the first hours of life, according to research presented at ESCMID Global 2026.

A major study presented today at ESCMID Global 2026 has found that antiretroviral therapy (ART) reduces accelerated biological ageing in people with HIV (PWH) by nearly four years, a finding that could transform how clinicians monitor HIV treatment and long-term health outcomes.
