Study links androgens to aggressive childhood brain tumor growth

An international team led by researchers at Baylor College of Medicine, Texas Children's Hospital, McGill University and University of Pittsburgh School of Medicine has discovered what drives the growth of a lethal pediatric brain tumor called Posterior Fossa Type A (PFA) ependymoma.

Stroke may trigger younger brain patterns in unaffected regions

In a new study published in The Lancet Digital Health, scientists at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) have discovered that the brains of people who experience severe physical impairment after a stroke may reorganize themselves in unexpected ways, showing signs of "younger" brain structure in undamaged regions as they adapt to injury.

Breast cancer cells exploit the lung's repair system to support tumor growth

Researchers at the CU Anschutz Cancer Center have discovered how breast cancer cells that spread to the lungs may take advantage of the body's natural healing response and how a commonly used drug might slow that process.

CDC tracks SARS-CoV-2 BA.3.2 global rise and finds early signals in U.S. wastewater

CDC surveillance shows that the highly divergent SARS-CoV-2 variant BA.3.2 spread to at least 23 countries and was detected in U.S. travelers, patients, airplane wastewater, and wastewater samples across multiple states. The report highlights wastewater and traveler-based genomic surveillance as early warning tools while noting that BA.3.2 has immune-evasion potential but has not rapidly displaced other circulating lineages.

Study finds AI-generated X-rays can fool radiologists and chatbots

Researchers found that both radiologists and multimodal AI models had only moderate success distinguishing synthetic radiographs from real clinical images, even when told fakes were present. The study warns that increasingly realistic AI-generated X-rays could be misused in medicine, research, insurance, and litigation, strengthening the case for watermarking, clinician training, and dedicated detection tools.

Can camel milk improve health? Review highlights benefits but warns against drinking it raw

A narrative review in Food Science & Nutrition examined studies published from 2000 to 2025 and found that camel milk contains bioactive compounds with potential glycemic, anti-inflammatory, gut, and other health benefits. It also stressed that raw, unpasteurized camel milk poses microbial and zoonotic risks, underscoring that safety remains a key part of the story.
