In this Review, Hossam Abdelsamed and colleagues discuss the different phenotypes and functions of CD8+ T cell subsets at different stages of atherosclerosis, as well as their roles in common comorbidities of atherosclerotic cardiovascular disease. The authors also highlight potential therapeutic strategies targeting CD8+ T cells and key knowledge gaps in our understanding of the role of these cells in atherosclerosis.
Chemists from Otto von Guericke University Magdeburg have achieved an important research success in the fight against resistant bacteria. The team led by scientist Professor Dr. Dieter Schinzer from the Institute of Chemistry has succeeded in producing key building blocks of the naturally occurring substance Neosorangicin A in the laboratory for the first time. This means it is now possible to develop Neosorangicin A in a targeted manner as a promising reserve antibiotic candidate to combat antibiotic resistance in the future.
To artificially produce the naturally occurring substance, the scientists used what is known as relay synthesis—instead of immediately creating the entire complex molecule, they first synthesized the critical sections, which served as staging points en route to the complete substance. The research success lies not only in the components produced but also in proof of the development process. The results have just been published in the journal Chemistry—A European Journal.
When the engineers used gene editing to suppress the PIEZO1 gene, the cells became “deaf” to the physical tugging. Even when the magnets vigorously exercised the gel, the blood vessels barely sprouted at all. This proved that physical force directly activates this cellular gatekeeper, signaling the vessel that it’s time to grow and branch out.
Engineering organized microvascular networks remains a critical challenge in tissue engineering and regenerative medicine. While biochemical approaches for patterning angiogenesis via growth factor delivery have shown promise, their inability to pattern sustained growth factors with spatiotemporal control limits effectiveness. Here, we demonstrate that dynamically patterned mechanical forces enable precise spatiotemporal control over angiogenic sprouting. We developed a magnetically actuated human vessel-on-a-chip platform that integrates a perfusable endothelialized microchannel within a collagen matrix and allows noninvasive and tunable mechanical stimulation across three spatial dimensions and time (4D). Using an automated 3-axis actuator, we systematically investigated how strain magnitude, frequency, and direction modulate endothelial cell behavior and vessel morphogenesis.
Welcome to functional immortality, folks.
I say functional rather than absolute because no one will ever REALLY live FOREVER. Even if we can reverse aging and become immune to all diseases (which is exactly what is happening right now even as I write this) there will still be accidents, suicides, wars, and murders. — Still…a BILLION years would be enough for me.
What about you?
A new study reveals that mature cells retain the ability to transform into stem cells after injury. The regenerative process, driven by macrophages, may offer new strategies for repairing damaged tissues.
This video breaks down exactly how China went from launching a national smart hospital initiative back in 2014 to deploying AI inside over three hundred hospitals by 2025, and eventually opening the world’s first fully integrated AI hospital in March 2026. You’ll see how AI triage systems, robotic pharmacies, and real-time diagnostic assistants are changing what a hospital visit actually looks like, and how this compares to healthcare systems elsewhere that are still struggling with weeks-long appointment waits and fax machines. Whether you find this exciting or concerning, this is a story about where healthcare technology is headed next, and it’s already happening.
One of the biggest challenges in cancer research has been linking the “big picture” seen in medical scans with the microscopic biology that drives tumor growth and dictates how patients respond to treatment. Now, by combining multiple imaging techniques (PET scans, bioluminescence and fluorescence), scientists can detect tumors across the whole body simultaneously, pinpoint key targets and then examine those tumors in detail, including the surrounding cells and tissue.
Study lead Professor David Lewis of the Cancer Research UK Scotland Institute and University of Glasgow said, This exciting technology allows us to build a clearer map of how cancer behaves at both a holistic and microscopic level.
It allows researchers to follow tumors in the body, identify the lesions that matter and then zoom in to study those cancer cells and their environment, giving us new information about cancer that we can take forward into better and more precise treatments.
The prevalence of obesity in the pediatric population is increasing, driven by a multifactorial etiology that includes genetic predisposition as well as both prenatal and postnatal influences. We aimed to explore associations between child physical activity (PA) at ages one and three years and body composition at age three. Furthermore, we investigated associations between maternal PA during pregnancy and child body composition at age three.
Mother-child pairs (n = 68) from a pregnancy PA intervention study were included. Children’s PA was assessed at one-and three-year follow-ups using 7-day accelerometry and categorized into 24-hour PA and daytime PA (6 a.m. – 8 p.m.). Child body composition was measured by Dual-energy X-ray absorptiometry and expressed as fat-free mass (FFM) and body fat percentage (BF%). Maternal moderate-to-vigorous intensity PA (MVPA) was measured using a commercial activity tracker. Associations between maternal and child PA and child body composition were examined using linear regression. Variables used for model adjustment included maternal pre-pregnancy body mass index, gestational weight gain, maternal educational level at baseline, parity, maternal age at baseline, child walking status at age one, child sex, and child age at the three-year follow-up.
We found a positive association between daytime PA at age one and child FFM at age three. Daytime PA at age three was positively associated with FFM, and 24-hour PA at age three was negatively associated with BF% and positively associated with FFM. A 10% increase in 24-hour PA was associated with approximately 400 g higher FFM. Maternal MVPA during pregnancy showed no association with child body composition at age three.
The nucleolus is a master regulator of ribosome biogenesis and cellular homeostasis, as well as an increasingly key determinant of neuromuscular diseases. Across these conditions, diverse genetic and molecular lesions converge on alterations in nucleolar organization and function. These changes impact ribosomal RNA synthesis and reshape translational output, linking nuclear events to cytoplasmic protein homeostasis in disease-relevant contexts. In this review, we propose a comprehensive framework in which the nucleolus integrates RNA dysfunction, genome organization, and translational control across neuromuscular disorders. This perspective provides a conceptual basis for interpreting disease heterogeneity and highlights nucleolar pathways as potential, underexploited targets for therapeutic intervention.
