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. This research ...

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 ...

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 ...

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 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 ...

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 ...

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, ...

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.

Liquid–liquid phase separation is a process in which a uniform solution separates into two coexisting liquid phases. In living cells, it governs the formation of membrane-less compartments that selectively concentrate molecules and regulate biochemical reactions. This phenomenon is also widely used in practical applications, including biomolecular separation and purification. A long-standing question in phase separation research is why specific molecules preferentially localize in one phase over the other. Conventional explanations have focused on polymer–polymer ...

Schizophrenia is a highly heterogeneous psychiatric disorder affecting ~1% of the global population, typically emerging in adolescence or early adulthood and characterized by hallucinations, delusions, disorganized thinking, and cognitive impairments; while its etiology remains elusive, genetic factors are widely recognized as fundamental, and GWAS have identified over 200 genome-wide significant loci.  White matter microstructure is essential for neural communication and is strongly heritable; diffusion tensor imaging (DTI) quantifies white matter integrity via FA, MD, and the three tensor eigenvalues (λ1–λ3), and widespread ...

Metastatic urothelial carcinoma has a poor prognosis: ~50% of muscle-invasive bladder cancer progresses to metastasis, and the 5-year survival for advanced/metastatic disease is <10%. Platinum-based chemotherapy was historically first-line, but its benefit is limited by renal insufficiency/poor tolerance and the lack of effective options after resistance. Immune checkpoint inhibitors have improved outcomes in a subset of patients and are supported by high tumor mutational burden and PD-L1 expression in bladder cancer; however, response ...

Hepatic steatosis is a core pathological feature of metabolic dysfunction-associated steatotic liver disease (MASLD). It not only drives disease progression to intrahepatic conditions such as cirrhosis but also elevates the incidence and mortality risk of cardiovascular diseases and extrahepatic malignancies. Importantly, hepatic steatosis is reversible in its early stages. Clinical practice guidelines recommend exercise intervention as the primary approach for treating the disease, and the concept of "exercise as medicine" is widely acknowledged. In recent years, researchers have mainly evaluated how different components of exercise prescriptions affect health ...

A new expert consensus made available online on 10 October 2025 and published in Volume 5, Issue 4 of the journal Intelligent Medicine on 1 November 2025, sets out a structured framework to assess large language models (LLMs) before they are introduced into clinical workflows. The guidance responds to the rapid uptake of artificial intelligence (AI) tools for diagnostic support, medical documentation, and patient communication, and the corresponding need for consistent evaluation of safety, effectiveness, and fairness. The consensus formalizes retrospective evaluation—testing ...

The rising incidence of cancer worldwide has led to an increasing number of surgeries that involve the removal of lymph nodes. Although these procedures play a major role in cancer staging and preventing the spread of malignancies, they sometimes come with severe long-term consequences. Since lymph nodes do not naturally regenerate once removed, their absence can lead to a condition known as secondary lymphedema. It manifests as chronic swelling, discomfort, and reduced mobility in affected limbs or regions, severely affecting a patient’s quality of life. Consequently, a major focus within the ...

New research published in Nature Ecology and Evolution reveals significant recent shifts in tree diversity among the tropical forests of the Andes and Amazon, driven by global change. The study, led by Dr Belen Fadrique from the University of Liverpool, uses 40 years of records on tree species collected by hundreds of international botanists and ecologists in long-term plots to offer comprehensive insights into tree diversity change in the world’s most diverse forests. Key Findings At the continental level, ...

Children with spina bifida, a malformation of the spinal cord that can lead to mobility impairments and hydrocephalus — a buildup of fluid in the brain — face significant risk of cognitive difficulties throughout their lives. A new multi-center study led by researchers at Washington University School of Medicine in St. Louis and Michigan Medicine finds that breathing problems during sleep are a widespread but often undetected issue among these babies and raises the possibility that early treatment might significantly improve ...

The North Atlantic Ocean is warming up. Higher temperatures and increased human activity in the region can trigger abrupt changes in marine ecosystems, for example how species are distributed and what they eat. In a long-term study published in Frontiers in Marine Science, researchers in Canada have examined the diet of three rorqual whale species and how these whales might have adapted their feeding habits as climate change and increasing human presence reshape the ecosystem of the Gulf of St Lawrence (GSL), a seasonally important feeding area for many whale species. “A ...

Wetland restoration is expanding worldwide, but long-term success often remains uncertain. Most projects rely on short-term, expert monitoring that ends long before restored wetlands stabilize, leaving major gaps in understanding how restored wetlands actually evolve over time. One increasingly discussed way to close these gaps is to extend monitoring beyond professional teams by engaging local communities and citizens in long-term observation. In a Perspective published (DOI: 10.1016/j.ese.2026.100656) in Environmental Science and Ecotechnology in January 2026, researchers from Aarhus University ...

New University of Hawaiʻi research confirms that “Sharktober” is real, revealing a statistically significant spike in shark bite incidents in Hawaiian waters every October. The study, which analyzed 30 years of data (1995–2024), found that about 20% of all recorded bites occurred in that single month, a frequency far exceeding any other time of the year. Researchers at UH Mānoa’s Hawai‘i Institute of Marine Biology (HIMB) Shark Lab published their findings in Frontiers in Marine Science. The research, led by HIMB Professor Carl G. Meyer, determined ...
