Summaries of the newly published research articles are provided below.
New Imaging Approach for Aggressive Breast Cancer
Researchers tested specialized amino acid PET tracers to image triple-negative breast cancer in mice. The tracers targeted cancer’s altered metabolism and showed strong tumor visibility, often outperforming standard 18F-FDG scans in tumor-to-normal tissue contrast, especially in the brain and muscle, suggesting a promising tool for future cancer imaging.
Advanced PET Tracer Highlights Aggressive Lung Cancer Lesions
A novel PET tracer, 68Ga-SSO120, was tested in patients with small cell and large cell neuroendocrine lung cancers. It successfully detected cancer lesions in most patients, including previously unseen metastases, offering a potential new tool to track disease alongside standard imaging and guide future targeted therapies.
PET Imaging Helps Predict Glioma Treatment Response
Researchers studied patients with relapsed high-grade gliomas receiving regorafenib. Early changes in amino acid PET scans, particularly a drop in tumor-to-brain ratio, were linked to longer survival, highlighting 18F-FET PET as a promising tool to identify treatment responders soon after therapy begins.
Brainstem Serotonin Patterns Differ in Parkinsonian Multiple-System Atrophy
Researchers studied serotonin transporter distribution in the brainstems of patients with MSA-P using 123I-FP-CIT SPECT scans. They found reduced serotonin in the midbrain and increased levels in the pons, a pattern confirmed by pathology, highlighting potential imaging markers for differentiating MSA-P from healthy individuals.
PET Imaging Offers Prognostic Insights in Malignant Pleural Mesothelioma
Researchers compared 68Ga-FAPI-46 and 18F-FDG PET scans in patients with malignant pleural mesothelioma. Tumor volume measured by both tracers predicted survival, with higher volumes linked to worse outcomes. 68Ga-FAPI-46 may complement standard imaging, providing prognostic information and guiding potential future targeted therapies.

Mount Sinai researchers help create largest immune cell atlas of bone marrow in multiple myeloma patients
2026-01-09
NEW YORK, (January 9, 2026) – Scientists at the Icahn School of Medicine at Mount Sinai, in partnership with the Multiple Myeloma Research Foundation (MMRF) and in collaboration with leading institutions across the country, have helped generate the largest single-cell immune cell atlas of the bone marrow in patients with multiple myeloma, a blood cancer that, while treatable, remains incurable. The findings, published in Nature Cancer, provide unprecedented insight on immune dysfunction in myeloma and could lead to improved tools for predicting which patients are at higher risk ...
Why it is so hard to get started on an unpleasant task: Scientists identify a “motivation brake”
2026-01-09
Background
Most of us know the feeling: maybe it is making a difficult phone call, starting a report you fear will be criticized, or preparing a presentation that’s stressful just to think about. You understand what needs to be done, yet taking that very first step feels surprisingly hard. When this difficulty becomes severe, it is known medically as avolition. People with avolition are not lazy or unaware: they know what they need to do, but their brain seems unable to push the "go" ...
Body composition changes after bariatric surgery or treatment with GLP-1 receptor agonists
2026-01-09
About The Study: In this single-center cohort study, both bariatric surgery and semaglutide or tirzepatide treatment were associated with substantial fat mass loss, moderate fat-free mass (FFM) loss, and improved FFM to fat mass ratio. These findings provide evidence to guide interventions aimed at preserving FFM while promoting fat loss.

Understanding sex-based differences and the role of bone morphogenetic protein signaling in Alzheimer’s disease
2026-01-09
Alzheimer’s disease (AD) is a serious neurodegenerative disease largely affecting older adults. Apart from age, it also shows sex-based differences, with women being more at risk. However, the origin of these differences remains unknown. While bone morphogenetic proteins (BMPs) play an important role in adult neurogenesis, their role in AD remains elusive. To address this, researchers have investigated sex-based differences and role of BMP signaling in neurogenesis in AD mice models, uncovering novel therapeutic targets.
Alzheimer’s disease (AD) is one of the main causes of dementia, characterized by progressive neurodegeneration, typically beginning at or after 65 years ...
Breakthrough in thin-film electrolytes pushes solid oxide fuel cells forward
2026-01-09
Under the threat of climate change and geopolitical tensions related to fossil fuels, the world faces an urgent need to find sustainable and renewable energy solutions. While wind, solar, and hydroelectric power are key renewable energy sources, their output strongly depends on environmental conditions, meaning they are unable to provide a stable electricity supply for modern grids. Solid oxide fuel cells (SOFCs), on the other hand, represent a promising alternative; these devices produce electricity on demand directly from clean electrochemical reactions involving hydrogen and oxygen.
However, ...
Clues from the past reveal the West Antarctic Ice Sheet’s vulnerability to warming
2026-01-09
The Thwaites and Pine Island glaciers, located in the Amundsen Sea sector of the West Antarctic Ice Sheet (WAIS), are among the fastest-melting glaciers on Earth. Together, they are losing ice more rapidly than any other part of Antarctica, raising serious concerns about the long-term stability of the ice sheet and its contribution to future sea-level rise.
To better understand the risks that warmer conditions pose to the WAIS, researchers are looking back to the Pliocene Epoch (5.3–2.58 million years ago), when global temperatures were about 3–4 ...
Collaborative study uncovers unknown causes of blindness
2026-01-09
Researchers from Radboud university medical center and University of Basel have discovered new genetic causes of inherited blindness. Their study shows that changes in specific pieces of DNA, which play a role in processing genetic information, can lead to retinitis pigmentosa. This eye condition affects about 1 in 5,000 people worldwide, causing ‘tunnel vision’ and often leads to legal blindness. The discovery provides clarity for dozens of families globally and opens new possibilities for diagnostics and counseling in hereditary conditions.
Retinitis ...
Inflammatory immune cells predict survival, relapse in multiple myeloma
2026-01-09
A new study maps the immune cell landscape of bone marrow in patients with multiple myeloma, a rare cancer that develops in the plasma cells of the bone marrow and has no cure. This large immune cell atlas, which includes robust patient outcome data, provides unparalleled new insights into how the immune system interacts with cancerous plasma cells and can be used to determine how aggressive a patient’s multiple myeloma is likely to be. The knowledge may improve survival predictions, guide treatment decisions and help in the development of new immune-based therapies for patients with multiple ...
