The effect of prestressed concrete also works in bones

https://www.mpg.de/18569011/bones-minerals-collagen

The hardness and strength of bones is also based on prestress that results from the mineralization of collagen. A team from the Max Planck Institute of Colloids and Interfaces has now demonstrated in experiments with tendons that this is a universal effect when minerals are deposited in the collagen.
These put the collagen under strain in the same way as hydroxyapatite particles,

Music in the time of corona

https://www.mpg.de/14777336/music-culture-covid19

Musicians and music lovers are hit hard by the COVID-19 pandemic. After all, music needs communities, but social distancing measures prevent rehearsals and concerts, cutting musicians off from their audience. In many places, musicians are now coming up with various creative ways to close this gap, especially via the Internet. Music thus creates new, virtual communities – an exciting phenomenon for musicology. Melanie Wald-Fuhrmann, Director at the Max Planck Institute for Empirical Aesthetics, has launched an survey into music in the time of corona together with colleagues from five other European countries.
At the same time, we will investigate whether music is also used as a substitute

plastic microfibers stay in the atmosphere much longer than spherical particles

How far microplastics travel in the atmosphere depends on particle shape, according to scientists at the University of Vienna and the Max Planck Institute for Dynamics and Self-Organisation in Göttingen: While spherical particles settle quickly, microplastic fibers stay in the atmosphere much longer. Thus they might even reach the stratosphere.
