When seawater penetrates concrete in road tunnels, a biofilm is formed that breaks down the concrete. This can lead to high costs and the risk of damage if stone and concrete drop from the tunnel roof.  In a new study, led by a team of researchers at Chalmers University of Technology in Sweden, research reveals the mechanisms behind the degradation, and its unexpectedly rapid progression.

To address the growing health threats posed by climate change, Nanyang Technological University, Singapore (NTU Singapore) is launching a new interdisciplinary research centre focused on climate change and environmental health in the tropics.

The use of AI-generated testimonials with increasingly realistic human features is becoming widespread on social media platforms like TikTok, even when it comes to communicating scientific content. It’s now quite common to come across videos where icons like Albert Einstein or Marie Curie — realistically recreated — explain relativity or radioactivity. But how do viewers react to these avatars? Does realism generate discomfort and thus mistrust, or can it actually improve understanding and the transmission of scientific information? A study published in the Journal of Science Communication (JCOM) explored how the realism of AI-generated avatars influences perceived trustworthiness in science communicators, also examining the role of avatars’ gender.
