A new study introduces ACA-SIM (atmospheric correction based on satellite–in situ matchup data), a neural-network-based atmospheric correction algorithm that uses real satellite–Aerosol Robotic Network-Ocean Color (AERONET-OC) matchups to improve the accuracy of atmospheric correction over coastal waters.
Following the path towards innovation in education and health, the Department of Education and Specific Didactics of the Universitat Jaume I is developing Hort4Health. Under the direction of Mireia Adelantado Renau, lecturer in the Department of Didactics of Experimental Sciences, this leading project seeks to analyse and investigate in an interdisciplinary way the impact of integrating an eco-educational garden in the classrooms where students learn about health, sustainability and emotional well-being, thus offering a solid scientific basis on the benefits of these practices.
The Hort4Health project emerges in response to the growing need to promote healthy habits among young people, especially in an era where technology and sedentary lifestyles predominate and generate worrying figures. Through practical activities in the garden, students not only study about agriculture and ecology, but also experience the benefits of physical activity and contact with nature for their mental and physical health. Researcher Mireia Adelantado points out that in this way "scientific results will be obtained on the current healthy habits of the university community, completing the scarce previous literature on this subject in this population". This initiative has already involved more than a hundred pupils from the Early Childhood and Primary School Teacher degrees, who have participated in sessions designed to improve their emotional wellbeing, their connection with the environment and their understanding of the importance of an active and healthy life. Early results indicate a significant positive impact on the physical health of the participants and underline the potential of the garden as an innovative space for learning and wellbeing.
A Chinese Medical Journal review details innovative approaches to overcome solid tumor microenvironment barriers for CAR-T therapy, including vascular normalization, chemokine engineering, physical barrier targeting, and novel delivery methods, alongside key clinical challenges.
Researchers have developed a new way to compress the memory used by AI models to increase their accuracy in complex tasks or help save significant amounts of energy.
Experts from University of Edinburgh and NVIDIA found that large language models (LLMs) using memory eight times smaller than an uncompressed LLM scored better on maths, science and coding tests while spending the same amount of time reasoning.
