New imaging method reveals nanodomains inside ALS-linked protein droplets

Inside the cell reside many tiny assembly factories and warehouses that gather together all of the proteins and RNAs-which carry out instructions from our DNA-that a living being needs.

Study reveals early mandibular catch-up growth in infants with Robin sequence

Robin sequence is characterized by micrognathia, glossoptosis, and often cleft palate, leading to airway obstruction and feeding challenges.

AI model outperforms breast density assessment in breast cancer risk stratification

An image-only artificial intelligence (AI) model for predicting the five-year risk of breast cancer provided stronger and more precise risk stratification than breast density assessment, according to a new study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

Head trauma impairs brain waste clearance in professional fighters

The brain's waste-clearing system significantly declines in function with repeated head impacts, according to a new study of cognitively impaired professional boxers and mixed martial arts fighters. The findings will be presented next week at the annual meeting of the Radiological Society of North America.

EACVI 2025 brings cardiac imaging experts together in Vienna

The European Association of Cardiovascular Imaging (EACVI), a branch of the European Society of Cardiology (ESC), will hold its flagship event, EACVI 2025, in Vienna, Austria from 11-13 December.

Poor lung gas exchange may help explain lingering brain symptoms in Long COVID

This study found that people with Long COVID more than two years after infection showed normal lung tests and brain structure, yet reported significant sleep and cognitive symptoms. Subtle correlations revealed that poorer lung gas exchange was linked with higher brain perfusion, worse sleep, and weaker executive function, suggesting a possible lung–brain connection.

Early first trimester scans improve detection of major fetal anomalies

Scanning for serious structural issues in fetuses during the first trimester can result in earlier detection of these issues, reports a new study led by Aris Papageorghiou at the University of Oxford, United Kingdom, published November 25th in the open-access journal PLOS Medicine.

Shorter hormone therapy may be enough for many men with prostate cancer

A study co-led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center found that most of the benefits of androgen deprivation therapy (ADT) for prostate cancer occur within the first 9 to 12 months.

White matter alterations connect coronary artery disease to cognitive decline

Individuals with coronary artery disease (CAD) - a constricting or blocking of blood vessels feeding the heart - face increased risks of strokes, cognitive impairment and dementia. However, the link between CAD and cognitive function is not fully understood.

Genetic signals reveal why erectile dysfunction develops and who is most at risk

This multi-ancestry genomic study identifies key genetic loci underlying erectile dysfunction and shows that ED risk is shaped by both cardiometabolic and substance use–related genetic pathways. Using EHR-linked data, the researchers uncover SIM1-related mechanisms, modest PRS performance, and bidirectional genetic links with obesity, diabetes, and addiction traits.
