Article Synopsis
- * The incorporation of Bi nanoparticles is facilitated by thiol groups, which help bind bismuth precursors and control nanoparticle growth, leading to a composite structure with enhanced catalytic properties.
- * The BiNP@Zr-DMBD-1 composite exhibited high efficiency for CO electroreduction and showed effective degradation of methylene blue dye under blue LED light, demonstrating its potential for various catalytic applications.
Ageing impairs the ability of neural stem cells (NSCs) to transition from quiescence to proliferation in the adult mammalian brain. Functional decline of NSCs results in the decreased production of new neurons and defective regeneration following injury during ageing. Several genetic interventions have been found to ameliorate old brain function, but systematic functional testing of genes in old NSCs-and more generally in old cells-has not been done.

Methods: Cross-sectional data from 829 adults ≥70 years of age were used. Abdominal, subcutaneous, and visceral AT and thigh muscle fat infiltration (MFI) were quantified by magnetic resonance imaging.
Article Synopsis
- Biopsies of muscle and adipose tissue can help understand aging, but they are invasive, especially for older adults with health issues like sarcopenia and frailty.
- The Study of Muscle, Mobility, and Aging (SOMMA) analyzed 861 older participants (ages 70-94) and found high success rates for muscle (97.1%) and adipose tissue (95.9%) biopsies.
- Most participants reported minimal pain during procedures, and adverse events were rare and not serious, indicating that these biopsies are generally safe and well-tolerated in older adults.
Aluminum alloys are used in advanced engineering applications as they possess a combination of favorable properties, including high strength, lightweightness, good corrosion resistance, machineability, and recyclability. Such applications often require forming the sheets into the final components, which is typically aided by an oil-based lubricant, followed by joining them using adhesives, which is hampered by residual lubricant. In this work, aluminum surfaces were modified with different self-assembled monolayers (SAMs), with the goal of significantly reducing the amount of lubricant while simultaneously improving friction properties, forming, and bonding performance.
