Researchers have identified a key protein that may help failing hearts regain function, offering new insight into why some hearts recover while others do not.

Inflammatory bowel disease (IBD), which comprises the inflammatory conditions Crohn's disease and ulcerative colitis, affects about 1.6 million Americans, many of whom cannot be effectively treated.

Most people have experienced the feeling: switching from one task to another, only to find the brain momentarily stuck in the old mode of thinking. Sometimes, even after realizing a strategy no longer works, the mind keeps returning to it anyway.

Researchers with the James P. Allison Institute™ at The University of Texas MD Anderson Cancer Center have discovered a new gene expression signature within tumors that can help identify patients with metastatic castration-resistant prostate cancer (mCRPC) who are more likely to experience lasting benefits from combined immunotherapy treatment.

A dual-threshold model for measuring the pancreatic tumor marker serum carbohydrate antigen 19-9 (CA19-9) identified patients with pancreatic cancer who had high-risk disease despite having low CA19-9 levels because of a genetic variation that impairs their ability to produce this biomarker.

New Curtin University-led research has found siblings of people with neurodevelopmental conditions in regional and remote Australia are struggling with poorer wellbeing and are more likely to feel overlooked.

Reusable catheters are just as safe for patients as single-use ones and do not increase the risk of urinary tract infections, a new study has found.

Eating foods that contain common preservative food additives may increase the risks of high blood pressure and cardiovascular disease, according to research published in the European Heart Journal today.

Scientists at La Jolla Institute for Immunology (LJI) have discovered that combining key vaccine ingredients could give the body the tools it needs to fight the entire family of arenaviruses with a single vaccine.

Researchers from The University of Osaka find that only a small fraction of T cells may drive the robust anti-cancer response seen in breakthrough multiple myeloma immunotherapy.

Surgeons are an integral part of the health care system, supplying critical and urgent care in nearly every field of medicine.

A study published in Economic Inquiry provides new evidence that universal free school meals can meaningfully reduce out‐of‐school suspensions in both elementary and secondary schools.

A large, multi-center study led by Ann & Robert H. Lurie Children's Hospital of Chicago derived "achievable benchmarks of care" (ABCs) using electronic health record data, which allows pediatric emergency departments across the country to set high yet realistic performance goals.

AD109, an investigational once-daily oral combination of aroxybutynin and atomoxetine, significantly improved airway obstruction and oxygenation in adults with mild-to-severe obstructive sleep apnea who could not use PAP therapy. However, symptom improvements did not clearly differ from placebo, and about one in five AD109 recipients discontinued treatment due to adverse events.

Conventional immune checkpoint inhibitors, such as anti-PD-1/PD-L1 and anti-CTLA-4 antibodies, can reinvigorate T cells but typically benefit less than 30% of patients.

GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

Calcium, vitamin D, or combined supplements offer little to no clinically meaningful benefit on fracture and fall prevention in most older people, finds an in-depth review of the latest evidence published by The BMJ today.

ERA is an AI system that uses large language models and tree search to automatically write, test, and refine scientific software for measurable research tasks. Across bioinformatics, COVID-19 forecasting, time-series analysis, geospatial modeling, neuroscience, and numerical computation, ERA produced expert-level solutions that often surpassed established human-developed methods.

Quitting smoking may be associated with a lowered risk of dementia, especially for people who avoid major weight gain after quitting, according to a study published May 20, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Migraine with aura was associated with an increased risk of ischemic stroke in middle-aged and older people, according to a study published May 20, 2026, in Neurology Open Access, an official journal of the American Academy of Neurology.
