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.

An outbreak of blue-green algae affecting the Murray River could last through April and even into May, authorities have warned.
A 700-kilometre stretch of the river is affected by algal blooms, from Lake Hume, near Wodonga in the state’s north-east, almost to Kerang in the north-west.

People have been warned not to eat or take mussels and other shellfish from Victoria’s Gippsland Lakes region, as health authorities test for a rare, potentially fatal toxin. High levels of the rare toxin Pseudo-nitzschia delicatissima, which is caused by algae blooms, was found in water samples taken at Eagle Point, Paynesville and Metung.

(American Chemical Society 13 January 2016) Many shore residents and beach-goers are already familiar with the health risks of ‘red tide,’ algal blooms along coastlines that can trigger respiratory illness and other effects in people who inhale the toxins the algae release. Now in ACS’ journal Environmental Science & Technology, scientists report new evidence that similar effects can occur on a much smaller scale among home aquaria owners.

Long-term exposure to a toxin produced by blue-green algal blooms can trigger tangles in the brains of animals similar to those seen in the brains of humans with Alzheimer’s disease and other neurological conditions, a study has found.
“As far as we are aware, this is the first time researchers have been able to successfully produce brain tangles and amyloid deposits in an animal … through exposure to an environmental toxin,” said the study’s lead author Dr Paul Alan Cox, an ethnobotanist at the Institute for EthnoMedicine.
The study, published in the journal Royal Society Proceedings B, also identified a common supplement decreased the number of brain tangles in animals exposed to the toxin.
