New heart assembloid model mimics complex valve disorders

A multi-disciplinary, multi-institution group of researchers focused their expertise in genetics, mechanics, chemistry and biology on a chip the size of a postage stamp in order to model a particular class of heart conditions.

LVIS stent-assisted coiling effectively treats wide-necked intracranial aneurysms

Intracranial aneurysms are weakened, bulging areas of cerebral arteries that can rupture, causing subarachnoid hemorrhage and, in turn, significant disability or death.

Lab-grown mini tumors help scientists predict breast cancer treatment success

Researchers at UC San Francisco have developed a new method to predict how different types of breast cancer will respond to treatment, using patient data from the I-SPY2 breast cancer trial and rapid testing on lab-grown mini tumors.

New multi-protein blood test accurately detects late-stage Alzheimer's disease

Researchers have identified seven proteins in the blood that could enable better blood tests for Alzheimer's disease.

One cognitive ability stood out in a study of Western diets and Alzheimer’s risk genes

A Western dietary pattern was associated with faster attention decline among older adults carrying the APOE ε4 allele, while no significant cognitive associations emerged for a Prudent dietary pattern. However, the Western diet association lost statistical significance after excluding participants with possible baseline cognitive impairment, making the finding exploratory.

Semaglutide slows blood protein signature linked to future dementia risk

A post hoc analysis of 2,970 older SELECT participants found that semaglutide slowed worsening of a 25-protein blood signature that predicts future dementia risk. Over 104 weeks, semaglutide produced larger effects on modeled 5-year than 20-year dementia risk, but whether these biomarker changes translate into less cognitive decline or dementia remains unknown.

Scientists create single-cell atlas of spinal neurons involved in motor coordination

Scientists at St. Jude Children's Research Hospital created a single-cell atlas of a key class of spinal neurons involved in motor coordination. From that resource, they identified a small subgroup of interneurons associated with the speed of rhythmic movements such as walking.

Phthalates may contribute to high blood pressure in pregnant women

Phthalates, which are chemicals found in plastics, personal care products and hundreds of other consumer goods, may contribute to high blood pressure in pregnant women, according to a study published in the Journal of the Endocrine Society.

New study uncovers metabolic vulnerability in high-risk myelodysplastic syndromes

Researchers at the University of Colorado Anschutz Cancer Center have identified a previously unknown metabolic weakness in the stem cells that drive high-risk myelodysplastic syndromes (MDS), a discovery that could lead to more targeted treatments for this aggressive blood cancer.

New gene signature predicts immunotherapy success for bone marrow cancers

A team led by researchers from the German Cancer Research Center (DKFZ), the HI-STEM Stem Cell Institute, and Medical Clinic V at Heidelberg University Hospital (UKHD) has characterized T cells in the bone marrow in cases of multiple myeloma and acute myeloid leukemia: A specific group of tumor-reactive T cells can recognize and, in principle, fight cancer cells, but is often not sufficiently activated.

Study reveals a previously unknown ability of the brain to repair itself

The brain evidently can regenerate itself better than previously assumed after injuries or certain autoimmune diseases.

Optimal prostate-specific antigen cutoff linked to improved prostate cancer survival

After treatment for metastatic prostate cancer, a drop in prostate-specific antigen (PSA) levels in the blood is an indicator that the treatment is working.

New combination therapy could permanently clear HIV in newborns

Every year, more than 120,000 newborns worldwide contract HIV, a global health burden that requires lifelong treatment for millions of people - assuming they have access and can afford it.

Medical reassurance often stops patients from seeking treatment

Doctors may think they're saying "Don't panic." But many patients hear "Don't bother" instead.

Tirzepatide lowers heart attack and cardiovascular event risk in adults with type 2 diabetes

In a US cohort of 52,971 adults with type 2 diabetes and established atherosclerotic cardiovascular disease, tirzepatide initiation was associated with a lower one-year risk of major adverse cardiovascular events than sitagliptin. The benefit was driven mainly by lower myocardial infarction and all-cause mortality hazards, although the authors cautioned that mortality findings may be influenced by residual confounding.

Study links better midlife vascular health to nearly 13 more dementia-free years

A long-term study of 12,409 adults found that a greater burden of diabetes, hypertension, and current smoking in midlife was associated with substantially fewer years lived free of dementia. Adults with none of these risk factors had about 30.1 dementia-free years from age 55, compared with 17.5 years among those with all three, a difference of nearly 13 years.

Simple biological age score flags higher cognitive decline risk in older adults

A study of 4,818 middle-aged and older Chinese adults found that higher light BioAge was associated with greater risks of cognitive impairment, episodic memory decline, and reduced mental intactness. The simple measure, based on age, creatinine, glucose, and CRP, added modest predictive information but requires further validation before clinical use.

Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Explainable AI helps predict dangerous bleeding after severe heart attacks

Researchers at Indiana University School of Medicine have developed and tested a six-point scoring system that can help identify patients at high risk of internal bleeding in damaged heart muscle after a severe heart attack using explainable artificial intelligence (XAI).
