New protocol screens clinical research participants for prior radiation exposure

A new study highlights a critical gap: most clinical research studies that use imaging techniques such as amyloid positron emission tomography (PET) scans do not account for the radiation participants have already received from prior medical procedures.

Study finds lower Alzheimer’s pathology in Black and Hispanic patients

A large multisite study of older people with cognitive impairment finds that Black and Hispanic people, while known to be far more apt to have dementia, are significantly less apt than other racial and ethnic groups to show Alzheimer's pathology on brain scans.

Scientists discover how vitamin K pathway regulates bone remodeling

Bone is continuously renewed through a process known as bone remodeling, in which osteoblasts (bone-forming cells) build new bone, while osteoclasts (bone-resorbing cells) remove older mineralized tissue.

Poor sleep may flag early Alzheimer’s risk in genetically vulnerable older women

Poorer subjective sleep quality was linked to worse visual memory and greater limbic tau burden in older women with higher genetic risk for Alzheimer’s disease. The findings suggest sleep complaints may help identify women at elevated risk for early AD-related brain and cognitive changes, but larger longitudinal studies are needed.

How does the brain recognize new faces and places in milliseconds?

This Communications Biology study used intracranial EEG in 22 epilepsy patients to map how the human brain processes new images of faces and places within milliseconds.. It found that visual information flows from the occipital cortex through parallel dorsal and ventral pathways toward frontal and limbic regions, with distinct timing patterns for faces and places.

Obesity drugs and surgery linked to greater fat-free mass loss

A new systematic review and meta-analysis of studies presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) shows that diet and exercise interventions result in a lower proportion of fat-free mass loss compared with obesity surgery or obesity drugs among people undergoing a weight loss of 10% or more.

PET/CT scans reveal biological activity of aggressive head and neck tumors

A research team led by the Medical University of Vienna has demonstrated in a recent study that the biological characteristics of a subgroup of head and neck tumors - which are very aggressive in many cases - are reflected in modern imaging techniques.

Interactive AI model improves explainable lung cancer diagnosis from CT scans

Lung cancer remains one of the leading causes of cancer-related deaths worldwide, making early and accurate diagnosis essential for improving patient outcomes.

Researchers map the brain histamine system to understand mental health

New research, from King's College London and the University of Porto, has mapped the histamine system in the brain. Histamine, a molecule more commonly associated with allergies, plays a separate but poorly understood role in brain function.

Brain artery widening may drive lacunar stroke more than artery narrowing

Abnormal brain artery widening is associated with lacunar stroke, indicating a shift in understanding the mechanisms behind small vessel disease in the brain.

AI-powered MRI scans predict diabetes and heart disease risk

Research shows AI-enhanced MRI body composition metrics can predict diabetes and heart disease risks, offering insights for better health screening practices.

AI and polarized light improve early detection of keratoconus

Keratoconus is a progressive eye disease that weakens and thins the cornea, the clear front surface of the eye. In its early, subclinical stage, the cornea can still appear normal on routine exams.

Identifying the ages when Alzheimer’s biomarkers sharply change

New research identifies critical ages for Alzheimer's biomarkers, enhancing screening strategies and understanding neurodegeneration across the aging spectrum.

AI model detects pancreatic cancer years before clinical diagnosis

An AI model (REDMOD) can pick up the very early subtle tissue changes of pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer, which conventional imaging and the human eye find difficult to detect, finds research published online in the journal Gut.

New optical imaging tool allows real-time breast cancer staging

Sentinel lymph node biopsy (SLNB) is critical to breast cancer staging, yet current assessment methods remain heavily dependent on pathology expertise and time-consuming tissue processing.

The simple link between core strength and brain health

The brain is more mechanically connected to the body than previously appreciated, scientists reported today (April 27) in Nature Neuroscience. Through a study using mice and simulations, the team found a potential biological mechanism underlying why exercise is thought to benefit brain health: abdominal contractions compress blood vessels connected to the spinal cord and the brain, enabling the organ to gently move within the skull.

Advanced cardiac CT detects hidden heart damage and future risk

Kumamoto University researchers discover that combining two advanced heart imaging techniques can predict life-threatening cardiovascular events with high accuracy.

Generative AI may help scientists connect the many layers of cancer

A Cell Perspective argues that generative AI models could help tackle cancer’s multiscale, multimodal complexity by complementing the Hallmarks of Cancer framework. It proposes that models capable of complex pattern recognition, multimodal fusion, and contextual reasoning could improve cancer detection, biological discovery, and precision oncology, while still requiring rigorous validation and human oversight.
