Human health and ecosystems could be affected by microbes including cyanobacteria and algae that hitch rides in clouds and enter soil, lakes, oceans and other environments when it rains, according to a Rutgers co-authored study.

Greenland Melting Likely Increased by Bacteria in Sediment

Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to Rutgers scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to a Rutgers-led study – the first of its kind – in the journal Geophysical Research Letters. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.

FAU Receives Florida Department of Health Grant to Study Health Effects of Harmful Algal Blooms

December 10, 2020 sarah Jonas Airborne Toxins, Algae, COVID-19, Cyanobacteria, Florida, Harmful Algal Blooms, Health Effects, Human Health, Microcystins, Red Tide, Toxins, urine sample

Despite many occurrences of red tide and blue green algae in Florida waters, the understanding of the health effects of exposure to these blooms is limited. Researchers will evaluate short- and long-term health effects of exposure to harmful algal blooms (HABS) in Florida to capture key areas of human exposure and a wide demographic population profile. They also will evaluate the potential effect of exposure to COVID-19 on susceptibility to HABs and health outcomes in this study population.

Scientists shed light on essential carbon-fixing machinery in bacteria

May 6, 2020 sarah Jonas Cells, Cyanobacteria, Metabolism

Scientists have been studying cyanobacteria and its many potential applications for decades, from cutting CO2 emissions to creating a substitute for oil-based plastics, but there wasn’t a deep understanding of the full life cycle and metabolism of specialized compartments within these common bacteria – until now.

New Method Detects Toxin Exposure from Harmful Algal Blooms in Human Urine

January 16, 2020 sarah Jonas 0 Comments Algae, Antibody, Cyanobacteria, Diagnostic Testing, Toxins, U.S. Centers For Disease Control And Prevention

A newly developed method can detect even low-dose human exposure to microcystins and nodularin in human urine. During harmful algal blooms (HABs), species of cyanobacteria release toxic peptides, including microcystins and nodularin into waterways, impacting wildlife and humans living in these marine environments. These findings are the first to report microcystin concentrations directly from exposed residents impacted by cyanobacteria in Florida, and is a critical step in developing and interpreting clinical diagnostic tests for HABs exposure worldwide.
