The rotating stall precursor is a major research focus in the field of aerodynamic compressor flow stability, as an accurate understanding of its physical mechanisms can help improve the operating margin of the compressor system in aircraft engines and ensure flight safety. With advances in numerical simulation techniques, the physical essence of spike-type stall has been increasingly investigated in depth. Many studies assume that weak-amplitude disturbances exist prior to stall and facilitate its onset; however, the specific nature of these disturbances, their relationship with the spontaneous unsteady behavior of the flow, and whether these disturbances serve as the origin of the spike-type stall, have yet to be clarified.
Laura Cancedda, head of the Brain Development and Disease Research Unit at the Italian Institute of Technology (Istituto Italiano di Tecnologia – IIT), has today been elected a member of the European Molecular Biology Organization (EMBO), the international community of more than 2,100 distinguished scientists in the life sciences field across Europe and around the world. Receiving EMBO Membership is a recognition of the excellence of her research and the outstanding achievements throughout her career.
Researchers from Ningbo University and The University of Hong Kong have proposed a novel 3D nanoprinting technique to fabricate high-resolution piezoceramic structures. This method enables precise control over PZT nanostructures with high elasticity and exceptional piezoelectric performance. Their breakthrough allows the creation of flexible, ultra-sensitive sensors, including a bionic air-flow sensor capable of detecting airflow as low as 0.02 m·s−1—nearly 10 times more sensitive than conventional designs.
This innovation paves the way for next-generation piezoelectric devices in industrial sensing, biomedical implants, and IoT applications, offering a scalable and efficient approach to high-performance nanomanufacturing.
Neuromorphic computing, which mimics architecture of brain, could support growing energy demands of AI
How can we understand what a society thinks without relying on traditional surveys that require large samples and significant investment? The Social Probing project, now completed and coordinated by researcher Antonio Fernández Anta at IMDEA Networks, was carried out in collaboration with UC3M, UPM, and Universitat Jaume I to achieve precisely that: develop scalable, cost-effective, and privacy-preserving tools that allow for continuous societal monitoring. Their solution: indirect surveys.
