Summary: This study successfully assembled colloidal quasicrystals by exploiting the geometry of nanoscale decahedra and the programmable bonding characteristics of DNA immobilized on their facets. The process is enthalpy-driven, works over a range of particle sizes and DNA lengths, and is made possible by the energetic preference of the system to maximize DNA duplex formation and favor facet alignment. The resulting colloidal quasicrystals exhibit specific structures with stacking disorder providing thermodynamic stability.

Summary: This study introduces the concept of Fourier lattice resonances (FLRs) and achieves complete control over the transmission spectrum of a metasurface by flexibly placing resonances. Based on standard lithographic fabrication methods, metasurfaces suitable for various optical cavity applications can be designed and manufactured.

Summary: This study aimed to assess the risk of acute myocardial infarction (AMI) after long-term exposure to respirable crystalline silica (RCS) and to explore differences in risk between men and women. The results showed that women exposed to RCS had a higher risk of AMI, while men had a relatively lower risk. In the highest quartile of cumulative exposure, the risk of AMI was higher for women. In conclusion, occupational exposure to RCS increases the risk of AMI, with women being more sensitive to RCS than men.

Summary: This study investigates the relationship between cobalt concentrations in inhalable and respirable dust fractions and develops conversion functions. The resulting power functions can be used to estimate cobalt concentrations in respirable dust in other studies. Limitations of using the conversion functions are discussed.

Summary: Dust produced by mining activities poses significant health and safety concerns. Inhalation of respirable coal mine dust (RCMD) and respirable crystalline silica (RCS) can cause obstructive lung diseases. Despite efforts to reduce dust exposure, the rate of respiratory diseases among mine workers remains high. This study investigates factors affecting RCMD and RCS dust concentrations in surface and underground mines. The results show higher RCMD concentrations in underground mines and higher RCS concentrations in surface mines. Additionally, RCMD concentrations are higher in the Interior region while RCS concentrations are higher in the Appalachia region. Smaller mines have lower RCMD and higher RCS concentrations. Finally, thinner coal seams have higher RCMD and RCS concentrations compared to thicker seams. The study suggests further research is needed to evaluate the effectiveness of the current monitoring system.

Summary: This study characterized personal exposure of workers fabricating aluminium trihydroxide-containing synthetic countertops, finding a nearly 100-fold range in respirable PM concentrations. The 15-min median concentrations increased until 2.35 hours, followed by a plateau, highlighting a need for early prevention measures.

Summary: Supramolecular hybrids of DNA and single-walled carbon nanotubes (SWCNTs) have been widely used in biosensing applications due to their unique optical properties. Aqueous two-phase (ATP) purification methods have been introduced to increase the retention time, optical performance, and stability of DNA-SWCNTs within cells. The findings provide evidence of how cells process engineered nanomaterials depending on their state of purification, which can contribute to the development of more robust and sensitive biosensors in the future.

Summary: The three criteria for political learning include opportunity, ability, and motivation. Passive learning models question the necessity of motivation for learning about politics. By conducting experimental studies with individuals given a choice in media content, researchers provide evidence for the limitations and circumstances of passive learning. The results suggest that passive learning occurs in situations where incidental exposure sparks motivation.

Summary: In recent years, researchers have increasingly explored nanoparticles derived from cellular membranes for disease prevention and treatment. These biomimetic nanoparticles, with their flexible design and effective interaction with the surrounding environment, can outperform traditional synthetic nanoparticles. Genetic manipulation has proven to be a robust and flexible method to generate nanoformulations with augmented functionalities. This review provides an overview of genetic engineering approaches to express novel surface proteins and discusses the various biomedical applications of genetically modified cellular nanoparticles.
