Summaries of the newly published research articles are provided below.
Tracking Kidney Cancer Spread with a New Targeted Imaging Tool
This study explored whether two biomarkers—CD70 and CAIX—help identify lung metastases from clear cell kidney cancer. Researchers also tested a new CD70-targeted PET/CT scan, 18F-RCCB6, to see how well it detects suspected metastatic tumors across the body.
When Heart Scans Work Best for Detecting ATTR Amyloidosis
Researchers tracked how a common imaging agent, 99mTc-pyrophosphate, behaves in the heart, blood, and bone to see whether early scans could match standard late scans for detecting ATTR amyloid cardiomyopathy. By comparing patients with and without the disease, they mapped when uptake peaks across different tissues.
Comparing Two Experimental Radiation Therapies for Neuroendocrine Tumors
This early-phase study tested how two radiopharmaceuticals—161Tb-DOTA-LM3 and the commonly used 177Lu-DOTATOC—deliver radiation to tumors and organs in the same patients. Using serial SPECT/CT scans, researchers measured how long each drug stayed in tumors and how much radiation different tissues absorbed.
A New Imaging Tool to Track Heart-Healing Cells After a Heart Attack
Researchers tested a new PET tracer, 64Cu-LNTH-1363S, in mouse models of heart attack to see whether it could identify fibroblasts that drive cardiac repair. Using two injury models and blocking studies, they evaluated how specifically and how strongly the tracer targeted these activated cells.
Nuclear Medicine in Africa: Mapping Progress and Remaining Gaps
This study surveyed nuclear medicine capacity across Africa, examining equipment availability, radiopharmaceutical access, workforce limitations, and growth trends. Data from International Atomic Energy Agency resources and regional experts highlight expanding PET/CT and SPECT services, increasing radiopharmaceutical options, and ongoing challenges that shape access to advanced diagnostic and therapeutic care.
Testing PET Tracers to Better Detect Alzheimer’s-Related Brain Changes
Researchers evaluated three different radioactive labels attached to a bispecific antibody, Lec-Fab8D3, designed to cross the blood–brain barrier and bind amyloid-β. In Alzheimer’s model mice, each tracer showed strong brain uptake, with clear differences in signal strength and regional contrast depending on the radionuclide used.

Smarter tools for peering into the microscopic world
2025-12-12
The microscopic organisms that fill our bodies, soils, oceans and atmosphere play essential roles in human health and the planet’s ecosystems. Yet even with modern DNA sequencing, figuring out what these microbes are and how they are related to one another remains extremely difficult.
In a pair of new studies, researchers at Arizona State University introduce powerful tools that make this work easier, more accurate and far more scalable. One tool improves how scientists build microbial family trees. The other provides a software foundation used worldwide to analyze ...
Applications open for funding to conduct research in the Kinsey Institute archives
2025-12-12
The Kinsey Institute invites applications for two competitive research awards that provide in-person access to the Institute’s internationally renowned Library & Special Collections at Indiana University Bloomington. These awards support original scholarship drawing on one of the world’s most significant archives on sexuality, relationships, gender, and human behavior—spanning manuscripts, publications, fine art, photography, ephemera, and scientific data across disciplines including biology, medicine, psychology, anthropology, ...
Global measure underestimates the severity of food insecurity
2025-12-12
(Santa Barbara, Calif.) — Before you can address a problem, you need to understand its scope. That’s why the United Nations developed the Integrated Food Security Phase Classification System. Aid organizations rely on analyses from this global partnership, which monitors and classifies the severity of food insecurity to help target assistance where and when it is most needed.
These analyses are multifaceted and complex — often taking place in regions where data is scarce and conditions are deteriorating — and stakeholders tend to assume ...
Child survivors of critical illness are missing out on timely follow up care
2025-12-12
When the unthinkable happens and a child is left critically ill or injured, the miracle workers in pediatric intensive care units around the country work tirelessly to save their lives.
Yet, after discharge from the hospital, many of these children could be missing out on vital follow up care, finds a study from Michigan Medicine.
“There aren't specific guidelines in terms of whether or when a child should follow up with their primary care physician or pediatrician after a stay in the PICU,” ...
Risk-based vs annual breast cancer screening / the WISDOM randomized clinical trial
2025-12-12
About The Study: In a randomized clinical trial, researchers found risk-based breast cancer screening was as safe as annual screening for detecting advanced cancers but did not reduce breast biopsy rates. Corresponding author Laura J. Esserman, MD, MBA, of the University of California, San Francisco, will present the study at the San Antonio Breast Cancer Symposium.

Early relapse predicts poor outcomes in aggressive blood cancer
2025-12-12
Mature nodal T-cell lymphoma is a type of rare and aggressive blood cancer. Limited data make it difficult to identify high-risk patients or tailor treatment strategies, so most patients receive similar care despite differences in disease characteristics and outcomes. A new study led by investigators from PETAL Consortium at the Mass General Brigham Cancer Institute found that among patients who achieved a complete remission after initial chemotherapy treatment, survival was worse for those whose disease relapsed within 12 months of initial treatment, suggesting that alternative strategies are needed to benefit these patients. The results are published in Blood.
“The study suggests ...

Clinical trial finds cannabis use not a barrier to quitting nicotine vaping
2025-12-12
Adolescent and young adult nicotine vaping has become an urgent public health concern, as 2024 marked the first year that nicotine vaping was the most initiated drug. Though vaping is the most common way young people use nicotine, few treatments exist to help those trying to quit. What’s more, a 2022 Drug Alcohol Dependence study reported around half of young people who vape nicotine also use cannabis, though the impact of this dual substance use on treatment outcomes remains unclear. A new clinical trial by investigators from Mass General Brigham found varenicline—a ...
Supplemental nutrition assistance program policies and food insecurity
2025-12-12
About The Study: In this cross-sectional study, adoption of state-level policies associated with higher Supplemental Nutrition Assistance Program (SNAP) participation was also associated with lower county-level food insecurity rates. Policies that lower barriers to SNAP participation may help address rising food insecurity rates observed in 2022 and 2023.
