An exciting #ICTC13 program is out ! Overall 108 oral presentations, 10 keynote/invited lectures, 124 posters, a cyano-metabolomics workshop, + lots of social activities.
Still time to register and experience the wildest cyanobacteria happening after the Great Oxygenation Event. 😜

There is no magic formula which toxins are expected with #cyanobacteria but the #microcystins and #anabaenopeptins we identified as indicators for different species in Lake Greifensee in a 5-year study seem to apply to many lakes in Switzerland.
To predict toxic algal blooms, researchers from #Eawag recommend a combination of species identification and chemical measurements. A study confirms that there is no magic formula and that specific indicator molecules are needed for each lake

How Switzerland cleaned up its rivers and lakes. This success story is encouraging when we address the next step: improving river morphology and riparian vegetation in a warming world.

From sewage and scum to swimming in ‘blue gold’: how Switzerland transformed its rivers
In the 1960s, the Swiss had some of the dirtiest water in Europe. Now, their cities boast pristine rivers and lakes – and other countries are looking to follow their lead
