- Scientists have developed a surface material that repels water droplets almost completely. The resulting superhydrophobic (extremely water-repellent) properties can be used as self-cleaning surfaces on vehicles or buildings. Even with extremely small inclination angles, water droplets rolled off. https://www.kit.edu/kit/english/pi_2024_105_novel-materials-with-almost-perfect-water-repellency.php 106 comments science
- Steroid hormones, such as sex hormones, which may cause male fish to develop female sexual characteristics, may accumulate in the environment and adversely affect humans and animals. New process can perform the photocatalytic degradation of these pollutants when they flow through polymer membranes. https://www.kit.edu/kit/english/pi_2022_032_water-processing-light-helps-degrade-hormones.php 13 comments science

- Computer attacks with laser light. Computer systems that are physically isolated from the outside world (air-gapped) can still be attacked. Data can be transmitted to light-emitting diodes of regular office devices using a directed laser. Critical IT systems need to be protected optically as well. https://www.kit.edu/kit/english/pi_2021_117_it-security-computer-attacks-with-laser-light.php 32 comments science

- Green areas in the inner city can directly improve the wellbeing of citizens. The larger the green areas in the neighborhood of the urban citizens are, the higher is the wellbeing. Persons, who reacted to green areas, were found to have a reduced activity in the dorsolateral prefrontal cortex. https://www.kit.edu/kit/english/pi_2019_104_green-areas-in-cities-promote-wellbeing.php 295 comments science
