For the first time, researchers have found that lung cancer patients who have a combination of high levels of depression and inflammation at diagnosis are later found with continuing depressive symptoms in the next several months, even as they receive new, promising therapies. The study found that having both maladies at diagnosis predicted higher, continuing levels of depression during the next eight months.

A new cancer treatment that delivers radiation directly to tumors by targeting two key markers simultaneously has been shown to be safe and effective in human trials. Acting like a "smart missile," the dual-targeting radiopharmaceutical is designed to attach to two vulnerable sites on cancer cells, enabling more precise and potent therapy. Early results show that nearly 90% of patients experienced either tumor shrinkage or disease stabilization.

A novel integrated molecular imaging approach enables precise localization and quantification of heart damage, as well as accurate identification of disease subtypes. The dual PET/MR and PET/CMR technique also provides direct evidence supporting surgery as a cardio-protective intervention in these patients, offering a comprehensive strategy for managing primary aldosteronism. This research was presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting.

For the first time, a new PET imaging technique has successfully visualized three radiotracers in a single scan, according to findings presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting. This innovation in multiplexed PET offers the potential to deliver a more comprehensive molecular profile of disease, enabling greater precision in both diagnosis and therapeutic assessment.

A cutting-edge brain imaging platform that integrates upright PET scanning, an augmented reality (AR) headset, and motion tracking enables researchers to study brain function in a more natural and dynamic way. Presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting, the new system—called Motion-tracked Immersive functional PET (MIf-PET)—allows participants to sit upright and interact with immersive tasks during scans.

Two newly developed PET imaging agents have been proven effective in identifying the histamine H3 receptor (H3R) that is highly expressed in neurological and psychiatric conditions. The novel agents have a long half-life, addressing key limitations of existing tracers and offering the potential to enable broader clinical imaging of H3R. This research was presented at the 2025 Society of Nuclear Medicine and Molecular Imaging Annual Meeting.

This week, medical researchers ruled out brainstem CT scanning alone for proof of neurologic death. Researchers at Yale presented new evidence that the brain stores and retrieves visuomotor associations in graph-like cognitive structures. And a new vision-language model generates inspection plans based on written descriptions without training.

Graphs, visual representations outlining the relationships between different entities, concepts or variables, can be very effective in summarizing complex patterns and information. Past psychology studies suggest that the human brain stores memories and experiences following graph-like and structured patterns, specifically as a network of associations, also referred to as cognitive graphs.

Will algorithms designed for interconnected computers hold up if some of the machines are not here on Earth but flying about in space, onboard satellites or spacecraft? Siddhartha Jayanti, assistant professor of computer science, is asking—and beginning to answer—questions that computer scientists must tackle as humans increase their footprint in space, bringing their machines with them.
