Chronic psychological stress can help tumors evade immune attack through a chain of molecular events involving gut bacteria and viruses within those bacteria, according to a study led by Weill Cornell Medicine investigators.

Markers of a new mechanism for cell death, called karyoptosis, have been found in brains of patients with Alzheimer's disease and frontotemporal dementia (FTD).

Our cells rely on tightly regulated signaling pathways to control when they grow, divide, and survive. When these regulatory systems are disrupted, cells can acquire the ability to grow uncontrollably and become cancerous.

Hepatitis B (HBV) and hepatitis C (HCV) are viral infections that can lead to health conditions such as cirrhosis, cancer, and potentially death if unmanaged. HBV can be transmitted through sexual contact, blood exposure, and mother-to-child transmission, while HCV is primarily transmitted through blood-to-blood contact.

High-dose DHA effectively increased brain levels in older adults at Alzheimer's risk, but did not lead to cognitive or structural brain health improvements.

Hypertrophic scars (HS) are abnormal outcomes of wound healing, marked by excessive extracellular matrix (ECM) deposition and impaired scar remodeling.

Your body absorbs alcohol much more rapidly after bariatric surgery. Patients need to know this when they choose the kind of surgery they will have.

Research led by the University of Bergen (UiB) and NORCE may help pave the way for a new vaccine targeting one of the world's leading causes of severe diarrheal disease.

Bacteria are becoming increasingly resistant to antibiotics. One alternative is treatment with viruses that exclusively infect bacteria, known as phages.

The British Heart Foundation is celebrating three incredible young women who donated their old hearts to science after having heart transplant surgery.

New research, published in The Journal of Immunology, identified biomarkers of a distinct immune profile that could be used to identify patients at risk for chronic critical illness (CCI) upon admittance to the intensive-care unit (ICU) after traumatic injury.

OMED Health ("OMED"), part of Owlstone Medical ("Owlstone"), the global leader in Breath Biopsy® for applications in early disease detection and precision medicine, and Welbeck Health Partners ("Welbeck"), one of the UK's largest specialist outpatient healthcare providers, today announced that Welbeck has adopted OMED Health's home-based Small Intestinal Bacterial Overgrowth (SIBO) breath-testing pathway. The roll out across Welbeck's network follows a three-month evaluation where the pathway was assessed for performance and impact on standard of care.

Patients with chronic pain do not have access to specialized rehabilitation on equal terms. Education, age, sex, and region of birth appear to play a role, particularly in combination, according to a Sweden-based study from the University of Gothenburg.

Researchers found that maternal plasma cell-free DNA methylation patterns in late pregnancy were associated with later autism diagnosis and maternal obesity in a high-likelihood ASD cohort. The findings suggest cfDNA may offer a minimally invasive way to study prenatal epigenetic changes linked to neurodevelopmental risk, but larger validation studies are needed.

Tecan, a global provider of laboratory automation and solutions, today announced the integration of Agentic AI capabilities into its lab analytics platform Introspect, leveraging NVIDIA BioNeMo Agent Toolkit.

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.

The 2025-2026 COVID-19 vaccines were associated with 50% estimated effectiveness against COVID-19-associated emergency department and urgent care encounters among immunocompetent US adults. They were also linked to an estimated 55% effectiveness against COVID-19-associated hospitalization, providing added protection beyond existing immunity from prior infection or vaccination.

Researchers at Hospital for Special Surgery (HSS) have identified a specialized population of immune cells that play a central role in driving abnormal tissue growth in rheumatoid arthritis (RA), offering new insight into disease progression and potential treatment strategies.

The availability of genetic testing for amyotrophic lateral sclerosis (ALS) for people with a family member diagnosed with the disease is expected to greatly increase the number of clinic visits to specialized ALS centers over the next decade, according to a study published June 24, 2026, in Neurology Genetics, an official journal of the American Academy of Neurology.

A UK Biobank study of nearly 390,000 people mapped 251 NMR-derived plasma metabolic traits against hundreds of health traits, prevalent diseases, and future disease outcomes. The atlas revealed tens of thousands of replicated associations, showed stronger prediction for selected short-term and cardiometabolic outcomes, and identified putative causal links that may guide future precision medicine research.
