Study highlights neurological and psychiatric impacts of long COVID

Nearly three years after the SARS-CoV-2 pandemic was declared over, conservative estimates suggest that between 80 million and 400 million people worldwide have long COVID.

New multiview AI architecture improves accuracy of heart disease diagnosis

Heart disease is the leading cause of adult death worldwide, making cardiovascular disease diagnosis and management a global health priority.

Rest tremor in Parkinson’s linked to better-preserved dopamine function

A Finnish clinical imaging study shows that rest tremor in Parkinson's disease is not explained by greater dopamine loss.

Fluorescent imaging enables real-time observation of Toxoplasma gondii's growth

It infects nearly one-third of the global population, yet its microscopic size makes the Toxoplasma gondii parasite difficult for scientists to study.

AI-driven OCT imaging system enables precise wound healing assessment

No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive and booked up with more pressing diagnostics.

New terahertz imaging system enables faster clinical diagnostics

Scientists at the University of Warwick have developed a fully fibre-coupled terahertz (THz) imaging system that significantly improves the speed, resolution, and clinical practicality of terahertz imaging.

AI-assisted decision support system improves stroke care and long-term outcomes

A clinical decision support tool that uses artificial intelligence (AI) to analyze scans after a stroke alongside treatment recommendations is associated with better quality care and long term outcomes for patients compared with usual care, finds a study from China published by The BMJ today.

Digital decision support tool improves outcomes in colorectal surgery

Research published in The Lancet Gastroenterology & Hepatology provides robust evidence for the use of a digital visualization and decision support tool in colorectal (bowel) surgery.

Hydration programs found insufficient to reduce kidney stone recurrence

Kidney stones can cause some of the most intense pain people ever experience, affecting daily life and leading many to hospital emergency visits.

Liquid biopsy enables rapid diagnosis of Burkitt lymphoma in Africa

In a study published today in Nature Medicine, researchers from the University of Oxford and the Muhimbili University of Health and Allied Sciences (MUHAS) in Dar es salaam, Tanzania have shown that a minimally invasive "liquid biopsy" test can diagnose Burkitt lymphoma rapidly and accurately in sub-Saharan Africa, where delays in traditional testing often prove fatal.

Brain lesions in Down syndrome show unexpected reversible changes

What has long been interpreted as permanent and irreversible vascular damage may not be exclusively so.

Expanded access to rotational atherectomy maintains safety in PCI procedures

Percutaneous coronary intervention (PCI) is a standard treatment for significant coronary artery disease. Cardiologists use a catheter to place a stent that opens up the blockage and restores blood flow to the heart.

A healthier thymus predicts longer life and lower cancer and heart disease risk in adults

Imaging-based analysis of over 27,000 adults shows that better thymic health is strongly associated with lower all-cause mortality, reduced lung cancer risk, and improved cardiovascular outcomes. The findings suggest the thymus remains biologically relevant in adulthood, linking immune aging, inflammation, and chronic disease risk, although causality cannot be established.

Menopause may raise women’s Alzheimer risk earlier than doctors once thought

This review argues that women’s higher Alzheimer disease risk may be shaped in part by midlife neuroendocrine aging, especially the menopause transition, rather than by longevity alone. It highlights early menopause, bilateral oophorectomy, vasomotor symptoms, and midlife cognitive changes as underinvestigated but potentially important risk markers, while calling for sex-specific, biomarker-driven prevention strategies.

New nanomaterial enhances bioimaging and targeted cancer drug delivery

The Nanomedicine and Nanotoxicology Group (GNano) at the University of São Paulo's São Carlos Institute of Physics (IFSC-USP) in Brazil has discovered a way to transform hydroxyapatite, a bioceramic material, into a nanoparticle with enhanced intrinsic luminescence.

Precise application of radio waves could help counter neurological conditions

A new study found that precise application of radio waves can change the activity of brain cells in ways that could counter neurological conditions.

Thymus health in adults linked to longer life and disease risk

Two new studies from investigators at Mass General Brigham challenge a decades-old assumption that the thymus, an organ best known for its role in establishing immune function in childhood, becomes irrelevant in adulthood.

Study finds GLP-1 medicines cut fat while preserving muscle function

Researchers found that GLP-1 medicines caused weight loss mainly through fat reduction, with only modest decreases in absolute muscle mass and no disproportionate loss of muscle function. In mice, physical performance improved, while in a small 12-week human pilot trial, strength was preserved despite reduced thigh muscle size.

New breath test could quickly diagnose bacterial infections

Infectious diseases are a major cause of death worldwide, and diagnosing bacterial infections remains a challenge in medicine.

New data platform transforms prediction and understanding of Alzheimer’s disease

A powerful new real-world data platform could transform how scientists predict and understand Alzheimer's disease and Alzheimer's disease related dementias (AD/ADRD), reports a new study at Columbia University Mailman School of Public Health and collaborators at the Vagelos College of Physicians and Surgeons, the School of Nursing as well as the University of Miami and University of Chicago.
