Cyanobacteria Blooms Exceed WHO Thresholds in Midwest Lakes

by Rebecca Dzombak 16 November 20216 June 2022

A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.

Longer Days Likely Boosted Earth’s Early Oxygen

Damond Benningfield, Science Writer by Damond Benningfield 3 September 202124 August 2023

Microbial mats in a Lake Huron sinkhole, combined with modeling work, suggest that the changing length of Earth’s day could have played a key role in oxygenating the atmosphere.

Lake Erie Sediments: All Dredged Up with Nowhere to Grow

by J. Besl 31 August 202129 March 2023

Agriculture is a key contributor to the algae mats that plague Lake Erie. With so many fertilizers entering the lake, could sediment from the lake floor be used to grow crops instead?

Desert Life Conjures Organic Carbon from Thin Air

by Elise Cutts 10 August 202122 December 2021

Without water, photosynthesis shuts down. To survive dry spells, desert microbes scavenge traces of hydrogen from the air and burn it for energy. Some even use hydrogen to fuel carbon fixation.
