Stranded dolphins have amyloid plaques in their brains

Dolphins stranded on the beaches of Florida and Massachusetts show in their brains amyloid plaques, a hallmark in human beings of Alzheimer's disease, together with an environmental toxin produced by cyanobacterial blooms.

Researchers discover neurotoxin in Lake Winnipeg

A new study from UBC's Okanagan campus has found that BMAA—a toxin linked to several neurodegenerative diseases—is present in high concentrations during cyanobacteria blooms in Lake Winnipeg.

Algal blooms reveal their poisonous past

A poisonous, "hairy efflorescence" in a 17th century Polish lake is likely to be the first recorded example of a toxic blue-green algal (cyanobacterial) bloom, according to environmental scientists at Flinders.

Researchers track the toxicity of Lake Erie cyanobacterial blooms

Efforts to reduce the amount of phosphorus and other nutrients washing off farm fields and into Lake Erie shifted into overdrive after high levels of a bacterial toxin shut down the drinking water supply to more than 400,000 ...

Algae blooms create their own favorable conditions, study finds

Fertilizers are known to promote the growth of toxic cyanobacterial blooms in freshwater and oceans worldwide, but a new multi-institution study shows the aquatic microbes themselves can drive nitrogen and phosphorus cycling ...

Runoff key to reducing certain toxic aquatic blooms

(PhysOrg.com) -- Many scientists believe that an unfortunate perfect storm of climate change and nutrient runoff will synergistically increase toxic cyanobacterial blooms globally in coming years.

If the water looks and smells bad, it may be toxic

Earthy or musty odors, along with visual evidence of blue-green algae, also known as cyanobacteria, may serve as a warning that harmful cyanotoxins are present in lakes or reservoirs. In a newly published USGS study of cyanobacterial ...
