Unusual high-energy phenomena detected deep in space are giving astronomers a rare opportunity to study some of the universe’s most extreme phenomena. On July 2, 2025, the Chinese-led Einstein Probe (EP) space telescope discovered an extremely bright X-ray source during a routine survey of the sky. The object’s brightness changed rapidly, quickly making it stand out from typical cosmic X-ray sources. This unusual detection triggered follow-up observations by observatories around the world. The research was coordinated by the EP Science Center of the National Astronomical Observatory of the Chinese Academy of Sciences (NAOC), and scientists from research institutions in China…

New research published in Alzheimer’s disease and dementia We provide evidence that genetic variations related to brain fluid movement interact with sleep quality and influence memory and brain structure in older adults. The findings suggest that the influence of a particular genetic profile on Alzheimer’s disease risk may be highly dependent on a person’s sleep quality. This points to sleep as a potential focus for protecting long-term brain health in individuals with certain genetic vulnerabilities. Alzheimer’s disease is a progressive neurological disease characterized by the gradual accumulation of a toxic protein called amyloid beta in the brain. Over time, this…

Children who are continuously exposed to high levels of naturally occurring radon gas in their homes may experience changes in the way their brains develop important attention and problem-solving skills. A recent study published in NeuroImage found that young people with high levels of chronic radon exposure showed changes in their brain wave patterns when completing tasks that required high levels of concentration. These electrical changes also affect how accurately children perform behavioral tasks, suggesting that typical brain maturation may be disrupted by common environmental toxins. Radon is a colorless and odorless gas produced by the natural decomposition of radioactive…

A new research collaboration reports the discovery and application of novel therapeutic strategies that selectively target EGFR and other kinases with controlled release in the tumor microenvironment to improve therapeutic efficacy, with promising results. The result is bioorganic chemistry. The study was carried out by researchers from the University of Eastern Finland, as well as North Carolina State University in the US, the University of North Carolina at Chapel Hill in the US, and the University of Oslo in Norway. Tyrosine kinase inhibitors (TKIs) are clinically limited by unwanted inhibition of epidermal growth factor receptor (EGFR) and other kinases in…

A new charter for the committee that advises the Centers for Disease Control and Prevention on vaccine use significantly refocuses the committee’s responsibilities, downplaying its role in recommending the use of new vaccines and giving it responsibility for evaluating alternatives for disease prevention. Previous committee charters emphasized the importance of experience related to vaccine research in selecting members, but the new version posted on the CDC website on Thursday only specifies that the entire committee “represents a balanced range of scientific, clinical, and public health expertise relevant to the committee’s mission,” a broad framework that could conceivably fit even those…

For the immune system to effectively fight pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping maintain immune tolerance. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have developed a powerful experimental method that allows them to generate Tfr cells from progenitor cells and study them in a targeted manner. The results were recently published in the journal Cellular & Molecular Immunology. Tfr cells control the development and function of so-called germinal centers in lymphoid organs such…

Three out of ten children and adolescents in Brazil complain of musculoskeletal pain (affecting bones, ligaments, and muscles). This common problem affects the lives of these people and should not be underestimated. This condition, known as disabling musculoskeletal pain, can cause children and adolescents to miss school and abandon daily activities and leisure activities, even though it is not related to trauma, repetitive strain, or any other specific cause. Research published in March in JJournal of Orthopedics and Sports Physiotherapy A study of 694 children and adolescents showed that 86% of people with disabling musculoskeletal pain recovered within 18 months.…

In a recently published study, Current molecular pharmacology discovered a novel mechanism by which long non-coding RNA PVT1 and translation initiation factor EIF4A1 cooperate to promote gastric cancer metastasis. Researchers showed that PVT1 binds to the N-terminal domain of EIF4A1 and that this interaction leads to increased expression of the secreted glycoprotein STC1. Elevated STC1 activates the Notch1 signaling pathway, promotes epithelial-mesenchymal transition, and significantly promotes tumor cell migration, invasion, and proliferation. Using 4D‑DIA quantitative proteomics and mass spectrometry, the research team identified STC1 as a key downstream effector of the PVT1/EIF4A1 axis. Immunohistochemical analysis of 183 gastric cancer tissues…

New research has revealed that a very specific form of electrical and magnetic brain stimulation can directly change people’s perception of whether they are in control of their actions. By targeting different areas on the right side of the brain, the researchers were able to improve or decrease the ability to detect external interference during computerized tasks. The results of this study were published in the journal NeuroImage. Imagine that when you trace a straight line with a pen, the ink appears one inch to the left. Your brain immediately recognizes that the visual result does not match the intended…

Research led by the Rourke Center for Trophoblast Research at the University of Cambridge has shown that single genes in human embryonic cells can be changed using genome editing techniques, allowing researchers to study the very early stages of human development in unparalleled detail. This technology, called base editing, is a more precise version of the genome editing technology CRISPR/Cas9. It has the potential to alter single nucleotide base pairs (the basic building blocks of DNA) within the approximately 3 billion base pair human genome. Researchers used base editing to block a gene called NANOG in very early-stage human embryos…
