Ever heard of Thalassiosira, Detonula, Leptocylindrus or Chaetoceros? No, they are not the names of Greek gods but arguably some of the most important and beautiful organisms on earth: the diatoms.
Diatoms are largely unseen due to their microscopic size but they are the most abundant and diverse single-celled phytoplankton (or microalgae) in the ocean.
These ancient lifeforms arose during the Triassic period, about 200-250 million years ago. They house themselves in intricate glass cases, the patterns and structures of which delight artists, architects and engineers as well as marine biologists.

VTT Technical Research Centre of Finland and the University of Turku have developed an easy-to-use and affordable blue-green algae (cyanobacteria) test. The testing device enables ordinary consumers to check that the water at their beach is free of cyanobacteria toxins. A commercialiser is now being sought for this rapid biodegradable testing device.
The cyanobacteria testing device, which is suitable for mass production and the size of a bank card, can be used both by consumers and authorities. The disposable, paper-based testing device can identify the occurrence of the most common cyanobacteria toxins, such as microcystins and nodularins.
“The cyanobacteria test requires only a few drops of water and indicates the result within 15 minutes. If two red lines appear on the display, the water contains cyanobacteria toxins. One line means that the water sample is toxin free,” explains VTT Senior Scientist Liisa Hakola.

(University of Hawaii at Manoa 27 May 2016) New research by scientists at the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology suggests that ingestion of toxic dinoflagellate Alexandrium fundyense changes the energy balance and reproductive potential of Calanus finmarchicus in the North Atlantic, which is key food source for young fishes, including many commercially important species.

On the second floor of Heidelberg University’s Gillmor Science Hall is a laboratory that produces some of the most important clues for Great Lakes scientists to predict outbreaks of toxic algae. Heidelberg’s National Center for Water Quality Research has been collecting data on phosphorus releases longer than any other group in the Great Lakes region, accumulating information about Lake Erie tributaries that helps researchers better understand how farm fertilizers and other nutrients get into water.
