Weekly semaglutide improves blood sugar and weight in adults with type 1 diabetes, clinical trial finds

When humans repeat specific patterns of behavior on a regular basis, these behaviors can become habits. Some habits, such as exercising in the morning, hygienic rituals, eating healthy or meditation practices, can be beneficial. Others, such as smoking, eating while watching TV or various forms of procrastination, can have detrimental consequences.

A new study from Washington University School of Medicine in St. Louis identifies a possible way to slow or block progression of age-related macular degeneration, a leading cause of blindness in people over age 50. The study appears in the journal Nature Communications.

Researchers at the Technical University of Munich (TUM) have developed a medical robotic system to relieve a life-threatening tension pneumothorax in the chest cavity. The researchers are presenting the robotic solution at the automatica robotics trade fair. In the future, it will be capable of telemedical operations during evacuation flights. It was developed as part of the iMEDCAP project.

Women who experience complications during pregnancy face a higher risk of stroke in the following decades, according to research published in the European Heart Journal.

Skin grafts genetically engineered from a patient's own cells can heal persistent wounds in people with an extremely painful dermatologic disease, a Stanford Medicine-led clinical trial has shown. The grafts treat severe dystrophic epidermolysis bullosa, or EB, a genetic condition in which the skin is so fragile the slightest touch can cause blistering and wounds, eventually leading to large, open lesions that never heal and are immensely painful.

Endoscopies could be replaced by far less invasive capsule sponge tests for half of all patients with Barrett's esophagus, a known precursor to esophageal cancer, according to a new study by researchers at the University of Cambridge, Addenbrooke's Hospital and Queen Mary University of London. The research was published in The Lancet.

Aimlessly wandering around a city or exploring the new mall may seem unproductive, but new research from HHMI's Janelia Research Campus suggests it could play an important role in how our brains learn.

Researchers at the University of California, Irvine have successfully performed preclinical laboratory testing of a replacement heart valve intended for toddlers and young children with congenital cardiac defects, a key step toward obtaining approval for human use. The results of their study were published recently in the Journal of the American Heart Association.

Human exposure to toxic particles drives various diseases. Examples include gout, an acute arthritis driven by monosodium urate crystals, or MSUc; CPPD disease, another inflammatory joint disease driven by calcium pyrophosphate dihydrate crystals, or CPPDc; and the lung disease silicosis, driven by inhaled silica-derived nanoparticles.

A study assessed the effectiveness of safeguards in foundational large language models (LLMs) to protect against malicious instruction that could turn them into tools for spreading disinformation, or the deliberate creation and dissemination of false information with the intent to harm.

The U.S. Food and Drug Administration has approved Monjuvi (tafasitamab-cxix) for the treatment of adult patients with relapsed or refractory follicular lymphoma.

A new cancer treatment that delivers radiation directly to tumors by targeting two key markers simultaneously has been shown to be safe and effective in human trials. Acting like a "smart missile," the dual-targeting radiopharmaceutical is designed to attach to two vulnerable sites on cancer cells, enabling more precise and potent therapy. Early results show that nearly 90% of patients experienced either tumor shrinkage or disease stabilization. These findings were presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting.

A newly developed PET radiotracer has shown the ability to produce high-quality images of real-time brain inflammation, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting and published as a supplement in the Journal of Nuclear Medicine.

A novel PET imaging approach has revealed distinct patterns of brain inflammation in patients with progressive apraxia of speech (PAOS), a rare neurodegenerative disorder that affects speech planning. These findings provide new insight into how neuroinflammation and tau pathology may drive disease progression in PAOS, opening potential avenues for earlier diagnosis and targeted treatments.

The combination of cochlear endolymphatic hydrops (CEH) and vestibular endolymphatic hydrops (VEH) on magnetic resonance imaging (MRI) accurately diagnoses Meniere disease (MD) and vestibular migraine (VM), according to a study published online May 13 in Frontiers in Neurology.

A cheese sold at Trader Joe's has been recalled due to listeria contamination.

Specific factors, including deep sleep and daytime urinary control, are associated with treatment-responsive nocturnal enuresis among children, according to a study published online April 23 in BMC Pediatrics.

A powerful heat dome is trapping scorching air and humidity across the Eastern U.S., bringing life‑threatening conditions through midweek.
