Green spaces play an important role for urban populations, whether by protecting against extreme weather events or providing space for recreation. In two studies, researchers at the Karlsruhe Institute of Technology (KIT) show just how much a diverse tree population affects microclimate, rainwater seepage and human well-being. Their results have been published in the journals Sustainable Cities and Society and Scientific Reports.
An international research team, led by scientists from Tel Aviv University and Sheba Medical Center, has unveiled an innovative method for activating adult stem cells from human bone marrow, enabling their expansion outside the body for use in bone marrow regeneration and the construction of a new blood and immune system.
IMDEA Networks has begun its participation in DISCO6G, an innovative project that will transform next-generation mobile networks, in collaboration with UC3M, UAM, and UPM and funded by the Madrid Regional Government. Its focus on Integrated Sensing and Communication (ISAC) enables network infrastructures not only to transmit information but also to function as distributed real-time sensors. "DISCO6G represents a paradigm shift, as it turns the network into a system capable of detecting its environment while communicating, something crucial for critical applications in transport and healthcare," explains Jesús Omar Lacruz, senior researcher at IMDEA Networks and principal investigator of the project at the institute.
Researchers at TU Delft (The Netherlands) and Brown University have developed scalable nanotechnology-based lightsails that could support future advances in space exploration and experimental physics. Their research, published in Nature Communications, introduces new materials and production methods to create the thinnest large-scale reflectors ever made. ‘This is not just another step in making things smaller; it’s an entirely new way of thinking about nanotechnology,’ explains Dr. Richard Norte, associate professor at TU Delft. ‘We’re creating high-aspect-ratio devices that are thinner than anything previously engineered but span dimensions akin to massive structures.’
MIT engineers devised a way to deliver drugs such as contraceptives by injecting them as suspended crystals. Once under the skin, the crystals assemble into a drug depot that can last for months or years, eliminating the need for frequent injections.
MIT scientists used light to control how a starfish egg cell jiggles and moves during its earliest stage of development. Their optical system could guide the design of synthetic, light-activated cells for wound healing or drug delivery.
Full Waveform Inversion (FWI) is capable of finely characterizing the velocity structure, anisotropy, viscoelasticity, and attenuation properties of subsurface media, which provides critical constraints for scientific problems such as understanding the Earth’s internal structure and material composition, earthquake preparation and occurrence, and plate motion and dynamic processes. In recent years, with advancements in high-performance computing platforms, improvements in numerical methods, and the cross-integration of multidisciplinary, FWI has demonstrated broad application prospects in deep underground structure exploration, resource and energy exploration, engineering geophysics, and even medical imaging. In this paper, we provide a comprehensive review and analysis of the development of the FWI method, addressing its current challenges, identifying key issues, future directions, and potential research areas in the theory, methodology, and application of high-resolution FWI imaging. The related findings were published in SCIENCE CHNIA: Earth Science, 68(2): 315‒342, 2025.
