Dawn Chorus is a project that combines conservation, science, and art. Under the motto Stop and Listen, it creatively brings humans and nature back together: People around the world take a minute in the morning to listen to the bird concert around them, record it, and upload it to a global database. This data is made available to art and science in order to gain insights into the conservation of biodiversity, for example. With the Dawn Chorus app, users can easily and quickly make their recordings. They can also learn more about bird songs and give free rein to their creativity – for example, with the media art feature "Sonic Feather," which transforms movement and sound into art. The app's data is only used in anonymous form and solely for scientific and artistic purposes. The app also works offline; in this case, the data is stored locally on the smartphone and can be uploaded later. Dawn Chorus was launched in 2020 as a citizen science and arts project by BIOTOPIA – Nature Museum Bavaria (Munich) and the Art and Nature Foundation (Nantesbuch), in collaboration with the Max Planck Society. The Bavarian State Association for Bird Conservation (LBV) is also a partner. More information at https://dawn-chorus.org/.

The earthquake in Turkey and Syria on February 6, 2023, was a magnitude 7.8 MW earthquake in the south of Turkey and the north of Syria. Some of our friends were directly or indirectly affected. From the shock of this event, the question arose of whether and how future earthquakes could be predicted. The idea of EQezzr was born. For this, we need your support. EQezzr" is the idea to use a mobile application with the artificial intelligence algorithms of "VOIZZR" to recognize earthquakes with the mission to predict them. The aim of this research is to train AI models based on sensor data as accelerometer, gyroscope, magnetometer as much as possible. EQezzr is a research project of the VOIZZR team. The app won't be tracking you and only collect this data when you actively interact with it. The data will be stored on EQEZZR servers. This app is available in English. More languages are in development.
