Aluminum die-cast components are widely used in automotive and precision machinery applications due to their combination of low weight and structural strength. However, internal defects known as porosity—voids formed by entrapped air during casting—remain a persistent challenge. These defects are difficult to detect through external inspection and can compromise mechanical integrity and long-term reliability.
Researchers from the University of Seville (US) and the Polytechnic University of Madrid (UPM) have demonstrated that it is possible to grow tomatoes and generate solar energy simultaneously, a key strategy for tackling global water scarcity. The study, carried out in Madrid and Seville during the spring of 2024, evaluated the use of agrovoltaic systems and regulated deficit irrigation to optimize water resources in tomato cultivation. The results show that, although using less water reduces the
Bottom fishing can release CO₂ from the seabed, but the consequences for the climate are not straightforward. New research, published in the Journal of Applied Ecology, shows that disturbing the seabed sets in motion multiple processes with contrasting effects. The overall climate impact of bottom fishing is the result of these processes and depends strongly on where fishing takes place and on whether carbon is released that would otherwise have remained stored in the seabed for long periods.
University of Birmingham experts have created open-source computer software that helps scientists understand how fast-moving particles behave when they interact with electromagnetic waves in space. Understanding how these particles behave in Earth's radiation belts is crucial because high-energy electrons can damage satellites, while radiation belt dynamics affect space weather forecasts. Better models help protect astronauts, power systems, and communications infrastructure.
