Researchers have developed a compact, wearable ultrasound device that monitors muscle activity. Attachable to the skin with an adhesive and powered by a small battery, the device wirelessly captures high-resolution images of muscle movements, enabling continuous, long-term monitoring. When worn on the rib cage, it effectively monitored diaphragm function for respiratory health assessments. When worn on the forearm, it accurately captured hand gestures, allowing users to control a robotic arm and even navigate virtual games. This new technology has potential applications in healthcare for conditions affecting muscle function, as well as in human-machine interfaces for more natural robotic control.

Well-being plays a critical role in maintaining job performance and the decision to stay abroad for expatriates. According to a new study from the University of Vaasa, Finland, strong organisational support and favourable working conditions improve their well-being at work, leading to improved job outcomes and reduced turnover. However, high-risk environments and conflicts between work and personal life can reduce well-being, leading to poor performance and an increased desire to quit.

Stanford type A aortic dissection (AD) is a degenerative aortic remodeling disease and carries a high mortality rate. It manifests distinct temporal patterns, transiting from acute, subacute to chronic stages. As an intimate pathophysiological feature of AD, aortic inflammation triggers disease initiation and progression. However, the precise subtypes of immune cells, their fundamental functional properties, and crosstalk with vascular cells across disease temporal transition remain largely unexplored. In a paper published in Science Bulletin, Junjie Luo from China Agricultural University, and colleagues analyzed 64,371 single immune cells by scRNA-seq coupled with TCR tracking using STARTRAC to quantitatively delineate the distinct functions and dynamic relationships of aortic immune cells in the context of temporal-specific AD. This study provides a comprehensive evaluation of how the composition of the immune landscape is altered in the aortic wall of diverse types of AD, and opens new avenues for a rational and precise anti-AD therapy by targeting TNF signaling.
