When water freezes into ice or boils into vapour, its properties change dramatically at specific temperatures. These so-called phase transitions are fundamental to understanding materials. But how do such transitions behave in nanomaterials? In Nature Communications, a team of scientists led by TU Delft presents new insights into the complex nature of phase transitions in magnetic nanomaterials. Their findings reveal the coupling between magnetic and mechanical properties, paving the way for ultra-sensitive sensors.
A recent study by the RPTU University Kaiserslautern-Landau shows extensive pesticide contamination in the landscape of the Upper Rhine Region. The research team led by Carsten Brühl shows for the first time that synthetic chemical pesticides from conventional agriculture do not remain on the cultivated areas, but spread from the lowlands to the Black Forest and the Palatinate Forest. The results show that the entire landscape is contaminated with pesticide mixtures, shedding new light on the potential environmental impacts of conventional agriculture. According to the researchers, pesticide use must be reduced urgently in order to protect areas around fields, orchards and vineyards.
Pollution by marine litter of anthropogenic origin –that comes from human activity– is currently one of the biggest environmental concerns given its increasing magnitude, especially due to the considerable amount of plastics present in the marine environment.
A study carried out by the University of Malaga and the Oceanographic Centre of the Balearic Islands (COB-IEO/CSIC) highlights the importance of making accurate estimates of the amount of these contaminants to face this challenge, which not only affects the scientific community but also the general publicMost people are familiar with loopholes. When your boss, landlord, partner, customer, or government asks you to do something you don’t want to do, and yet you can’t say “no,” you may resort to malicious compliance – doing what someone asked, but not actually what they meant. Most parents are probably familiar with such “little lawyer” behavior too: if a parent says, “Time to put the tablet down,” a child might physically put the tablet down on the table – and then keep playing on it. While such intentional misunderstandings are common and important, there has been little research on the development of loophole behavior across childhood. In a new Child Development study from the Society for Research in Child Development (SRCD), researchers at the Massachusetts Institute of Technology and Harvard University examined when and why children engage in loopholes. Tracing the origin of loophole behavior and how communication goes wrong can help us to better understand how communication often goes right, when people are motivated to cooperate. This may be the first research to explore the phenomenon of loopholes across development and can help contribute to a broader understanding of social reasoning.
