In this research, a rationally-designed strategy was employed to address the crucial issue of removing nano-plastics (NPs) from aquatic environments, which was based on fabricating sea urchin-like structures of FeO magnetic robots (MagRobots). Through imitating the sea urchin's telescopic tube foot movement and predation mechanism, the unique structures of the MagRobots were designed to adapt to the size and surface interactions of NPs, leading to a high efficiency of NPs removal (99%), as evidenced by the superior performance of 594.3 mg/g for the removal of polystyrene (PS) nanoparticles from water, with 3300% increase over magnetic FeO without structural design.

Planar microsupercapacitors (MSCs) are of great value for flexible and wearable electronics. The rational design of electrode materials with rapid ionic kinetics and sufficient active site exposure is critical but challenging for realizing high-energy MSCs. Herein, we report the dot-tube-sheet multidimensional heterostructure films (MHFs) with versatile patterns by a simple mask-assisted strategy, consisting of 0D carbon dots (CDs), 1D carboxyl-carbon nanotubes (c-CNTs), and 2D TiC MXene nanosheets.

Polymerase chain reaction (PCR) with probe-based melting curve techniques has been widely used in multiplex genotyping for early diagnosis of genetic diseases and common cancers. However, traditional designs face limitations due to the high modification cost of sensing probes and complex background fluorescence signals. Herein, we introduce the Universal Melting Probes (Uni-Melt) system, a closed-tube PCR assay for multiplex genotyping that incorporates barcoded PCR amplification and universal hybridization probes for melting curve analysis.

Background: Insecticides are a crucial component of vector control. However, resistance constitute a threat on their efficacy and the gains obtained over the years through malaria vector control. In Gabon, little data on phenotypic insecticide resistance in Anopheles vectors are published, compromising the rational implementation of resistance management strategies.

Currently, in dairy farming, there is growing concern for the welfare of calves during the critical period between the separation from their dams and weaning. During weaning, rationed feeding is a practice used to improve feed efficiency and control the calves' growth, but it could also have negative consequences associated with hunger and feed restriction behavior. One such consequence could be the performance by calves of stereotyped behaviors indicative of poor welfare, such as non-nutritive oral behaviors.
