Photovoltaic systems are increasingly being installed not only on roofs but also on open land. This does not always meet with citizens’ approval. What is known as agrivoltaics (Agri-PV), however, is viewed more favorably, as researchers at the University of Bonn have now been able to show. In this case, the solar cells are installed in spaces used for agriculture – such as on pastures or as a canopy over grapevines. According to a survey of almost 2,000 people, this form enjoys much higher acceptance than normal solar parks. The study has been published in the journal Land Use Policy.

Messages intended to stop users from endless scrolling on social media may have the opposite effect, according to a new study. 

African elephants are the largest land animals on earth and significantly larger than their relatives in Asia, from which they are separated by millions of years of evolution. Nevertheless, Asian elephants have a 20 percent heavier brain, as scientists from Humboldt-Universität zu Berlin and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) were able to demonstrate together with international colleagues. They also showed that elephant brains­ triple in weight after birth. These results, published in the scientific journal “PNAS Nexus”, provide potential explanations for behavioural differences between African and Asian elephants as well as for the pachyderms' long youth, during which they gain enormous experience and learn social skills.

Americans perceive small juries of content experts as the most legitimate moderators of potentially misleading content on social media, according to a survey, but perceive large, nationally representative or politically balanced juries with minimum knowledge qualifications as comparably legitimate.
