Summaries of the newly published research articles are provided below.
Targeting the Tumor Microenvironment with a New FAP Radiotracer
Fibroblast activation protein (FAP) is abundant in many tumors, making it an attractive target for imaging and therapy. This study introduces 3BP-3940, a new FAP-targeting peptide. Preclinical testing showed strong tumor uptake, high specificity, and effective tumor growth inhibition when paired with lutetium-177, with low uptake in healthy tissues.
Uncovering LATE: A Hidden Mimic of Alzheimer Disease
Limbic-predominant age-related TDP-43 encephalopathy (LATE) often resembles Alzheimer disease in older adults. Using 18F-FDG PET and MRI from nearly 1,000 patients, this study identifies distinct metabolic and structural brain patterns that differentiate probable LATE, Alzheimer disease, and their frequent overlap.
Boosting Tau PET Detection in Progressive Supranuclear Palsy
Tau PET imaging often struggles to detect four-repeat tau in disorders like progressive supranuclear palsy (PSP). This study shows that removing background signal patterns from PET scans improves sensitivity, helping distinguish PSP from healthy controls and revealing clearer disease-related brain changes across PSP variants.
Predicting Mesothelioma Outcomes with FAPI PET Imaging
Fibroblast activation protein imaging may offer new prognostic insight in malignant pleural mesothelioma. This study compares 68Ga-FAPI-46 PET/CT with standard 18F-FDG PET, showing that tumor volume measures from both scans strongly relate to patient survival, highlighting FAPI PET as a promising tool for risk stratification.
FAP-Targeted Radiotherapy for Pleural Metastases Shows Promise
Pleural metastases signal advanced cancer with limited treatment options. In this retrospective study, patients with FAP-positive pleural disease received ¹⁷⁷Lu-FAP-2286 after standard therapies. Imaging and survival analyses showed meaningful disease control, longer survival in responders, and good agreement between FAP PET and CT response measures, with treatment generally well tolerated.

ISSCR statement in response to new NIH policy on research using human fetal tissue (Notice NOT-OD-26-028)
2026-01-23
The abrupt ending of NIH support for fetal tissue research will undermine the development of new therapies for diseases that affect American families. Research with human fetal tissue (HFT) and HFT-derived cell lines has been integral to biomedical progress for nearly a century and has long been supported on a bipartisan basis under many U.S. administrations. This research has contributed to fundamental advances in understanding human development, infertility, infectious diseases, and chronic and neurodegenerative conditions. HFT-derived cell lines have played a critical role in the development of vaccines that have saved millions of lives worldwide.

Biologists and engineers follow goopy clues to plant-wilting bacteria
2026-01-23
Slippery, drippy goop makes Ralstonia bacteria devastating killers of plants, causing rapid wilting in tomato, potato and a wide range of other crops, according to new research. The work, published Jan. 22 in Proceedings of the National Academy of Sciences, comes from an unusual collaboration between plant pathologists and engineers at the University of California, Davis.
Ralstonia solanacearum can lurk in damp soils for years before infecting a plant, spreading rapidly through the water-carrying vessels (xylem). Infected plants wilt and die within days.
“My analogy is that they cause a heart attack for plants, because they clog up the vessels and ...
What do rats remember? IU research pushes the boundaries on what animal models can tell us about human memory
2026-01-23
In a new study Indiana University researchers observed episodic memory in rats to a degree never documented before, suggesting that rats can serve as a model for complex cognitive processes often considered exclusively human. Unlike semantic memory, which involves isolated facts, episodic memory involves replaying events in the order and context in which they occurred.
“The ability to replay a stream of episodic memories in context suggests that rats can serve as a model for complex cognitive processes,” said ...

Watching forests grow from space
2026-01-23
Forests are central to climate mitigation, yet tracking how fast they grow over decades remains difficult. A new satellite-based approach reconstructs forest canopy height changes across southern China from the 1980s onward. The analysis reveals sustained forest growth, clear differences between plantation and secondary forests, and the dominant role of management in shaping forest structure. The results show that long-term forest development can be monitored consistently from space.
Forest canopy height reflects tree growth, biomass accumulation, and carbon storage potential. While ...
New grounded theory reveals why hybrid delivery systems work the way they do
2026-01-23
New research into project management in software engineering shows that the most successful systems are not the ones that follow a fixed blueprint from the start, but those that evolve in response to real challenges as projects unfold.
Hybrid delivery models are born out of practical necessity when teams face complex and competing demands in software projects, and they improve over time as those teams adapt to real-world pressures.
The research offers reassurance that messiness and adjustment are not signs of failure, but normal features of working in complex environments.
The paper, titled The Pragmatics of Hybridity: A Grounded Theory of Method Integration ...
CDI scientist joins NIH group to improve post-stem cell transplant patient evaluation
2026-01-23
An international task force of medical experts recently proposed major revisions to the way doctors measure treatment success for a common–and often severe–skin complication of stem cell transplantation.
The National Institutes of Health (NIH) Consensus Project Task Force recently published a report of their refined approach in the journal, Transplantation and Cellular Therapy.
CDI Faculty Member Rachel Rosenstein, M.D., Ph.D., co-authored the report. With her colleagues, she helped present ways to develop better response criteria for clinical trials evaluating impact of treatment on skin involvement in graft-versus-host ...
Uncovering cancer's hidden oncRNA signatures: From discovery to liquid biopsy
2026-01-23
We knew we had something interesting with T3p, a single small RNA found in breast cancer but absent from normal tissue. After being described in 2018, this molecule took our team on a six-year journey to systematically map orphan non-coding RNAs (oncRNAs) across all major cancer types, understand which ones actually drive disease, and demonstrate their utility in monitoring patients through simple blood tests.
In a paper published today, we show how we went from mining cancer genome data to building machine learning classifiers, ...
Multiple maternal chronic conditions and risk of severe neonatal morbidity and mortality
2026-01-23
About The Study: In this study, risks of severe neonatal morbidity or mortality increased with an increasing number of preexisting maternal chronic conditions. These findings suggest that women and adolescents with multiple chronic conditions may benefit from preconception counseling to optimize chronic disease management, monitoring in pregnancy for earlier identification of complications, and enhanced newborn supports.
