Summary: Engineered colloidal nanoparticles have great potential in biomedical applications, with the ability to indirectly affect cell behavior by sequestering molecules from the biological environment. Experimental results demonstrate that gold nanoparticles with specific surface chemistries can significantly reduce chemotaxis of THP-1 cells.

Summary: Limited recycling options and large stockpiles of gold tailings can lead to social and environmental issues, which can be alleviated through recycling. This study investigated the possibility of producing sintered bricks from gold mine tailings, with optimized process parameters found to be crucial for the properties of the bricks. Clay content, forming moisture, and sintering parameters were all found to have different correlations with the properties of the sintered bricks.

Summary: To cope with nutrient scarcity, plants employ two main strategies - stopping growing to reduce nutrient demand, and searching for nutrients through physiological and morphological responses in roots. The interconnection between these strategies is not well understood, but recent research suggests that the plant hormone ethylene may play a crucial role in connecting them. The TOR system is known to be a central regulator of growth in response to nutrients, and ethylene activation is involved in many nutrient deficiency responses.

Summary: Mine tailings from the decommissioned Remance gold mine in Panama contain high concentrations of potentially toxic elements and cyanide, posing serious ecological risks for soils and biota in the surrounding areas. Remediation efforts are necessary to address the pollution and environmental risks posed by the mine waste.

Summary: Acid mine drainage (AMD) caused by the oxidation of sulphide minerals in mine waste is a global concern, and this study evaluated the acid-neutralising capabilities of different mine tailings and their potential use in preventing and treating AMD. The results showed that alkaline mine tailings have a high acid-neutralising capacity and can be used as pH neutralising cover materials.

Summary: There is a need for novel drug targets to reduce body mass index (BMI) and combat the global obesity epidemic. Previous studies have suggested that loss of GPR151 function is associated with decreased BMI and reduced risk of type 2 diabetes (T2D). In this study, the researchers investigated GPR151 using the Pakistan Genome Resource (PGR), one of the largest biobanks of human gene knockouts. They identified and confirmed eleven loss-of-function variants of GPR151 in the PGR participants, but found that GPR151 deficiency was not associated with clinically significant differences in BMI or metabolic traits. Moreover, experiments on Gpr151 knockout mice also showed no significant effect on body weight. Therefore, the researchers concluded that inhibiting GPR151 may not be an effective therapeutic approach for treating obesity.

Summary: The 2015 Gold King Mine spill had significant impacts on the activities of the Dine (Navajo) people, with reductions in livelihood, dietary, recreational, cultural/spiritual, and arts and crafts activities. This reduction may result in long-term trauma and affect the passing down of traditions to future generations. The study emphasizes the importance for scientists and disaster responders to consider the cultural and spiritual impacts on Indigenous communities when responding to environmental disasters and conducting risk assessments.

Summary: This study integrates field observations, remote sensing data, geochemical, and isotopic analyses to assess the environmental impacts of cyanidation and mining activities in the Sukari gold mine. The findings indicate groundwater contamination with cyanide due to leaks from the tailings storage facility constructed over a fractured basement aquifer.

Summary: The results of the study suggest that high water hardness and electrical conductivity in tap water can have a negative impact on the production of Aedes mosquitoes. Therefore, it is important to consider the level of water hardness and electrical conductivity when rearing mosquitoes for release purposes. Overall, water with hardness of more than 140 mg/l CaCO3 or electrical conductivity more than 368 mu S/cm is not recommended for optimal rearing of Aedes mosquitoes.

Summary: By partially replacing magnesium oxide (MgO) with gold mine tailings (GT) in cement, the paper found improved workability and compressive strength, along with a denser microstructure. Incorporating GT in the cement structure leads to the formation of new types of hydrates, enhancing compressive strength. Partial replacement of M reduces costs and enhances the mechanical properties of MKPC.
