Inspired by the natural spider web structure, this study innovatively designed an omnidirectional strain sensor array with a bioinspired spider web configuration. Using Ti₃C₂T_x (MXene) conductive ink and 3D printing technology, the sensor array was successfully fabricated. The strain sensor array leverages the isotropic strain response characteristics of the spider web structure, combined with a multi-class multi-output neural network, to achieve signal decoupling of the sensor array, enabling accurate identification and differentiation of both strain direction and magnitude. Within the 0-10% strain range, the sensor demonstrated a gauge factor (GF) of 26.3, with an identification accuracy of approximately 97% for strain magnitude and direction under various surface stimuli. This research provides a novel approach for achieving both high sensitivity and reliability in strain detection, demonstrating potential applications in human motion monitoring and multi-directional stress sensing. Furthermore, it offers promising prospects for applications in intelligent robotics and wearable health monitoring devices.

Alveolar bone defects can cause periodontal dehiscence, leading to exposure of dental roots, recession of gums, and increased tooth sensitivity. In a new study, researchers have evaluated the therapeutic potential of abaloparatide (ABL), a synthetic analog of human parathyroid hormone-related protein(PTHrP), in alleviating periodontal dehiscence. Utilizing rat models undergoing orthodontic tooth movement, they demonstrate that submucosal injection of ABL induces alveolar bone formation through a focal adhesion kinase(FAK)-driven mechanism.

A collaborative research team from Peking University has developed a novel method to enhance the tumor-targeting efficiency of γδ T cells through chemical engineering. By conjugating or gluing the cancer cell-targeting antibodies to γδ T cells via fast metabolic glycan labeling and click chemistry, the team achieved improved anti-tumor efficacy both in vitro and in vivo. This innovative approach holds significant promise for advancing adoptive cell therapy in cancer treatment.

A study conducted in mice by scientists from the Institut Pasteur and Inserm reveals that maternal consumption of dietary emulsifiers can have a negative impact on the gut microbiota of their offspring. These microbiota alterations are thought to significantly increase their risk of developing chronic inflammatory gut disorders and obesity in adulthood. The harmful transgenerational effects of maternal consumption of emulsifiers on the health of offspring highlight the need for additional research in humans on the impact of direct exposure to emulsifiers during early childhood. These findings were published in the journal Nature Communications.
