A new U.S. Geological Survey study that looked at the extensive harmful algal bloom that plagued Florida last year found far more types of cyanobacteria present than previously known.

Professor proposes using artificial intelligence to predict aquatic ecosystem health
Lassonde School of Engineering Professor Usman Khan‘s research on the measurement of aquatic ecosystem health has been published in the journal Water.
In the paper, Khan proposes an approach based on artificial intelligence to predict dissolved oxygen in an urban river environment.
Like a slice of pizza, a curvature could give fish fins their strength
Pizza enthusiasts know well that a simple u-shaped curvature at the crust can keep a thin slice from drooping over when lifted from a plate. A team of engineers from Brown University has shown that fish may take advantage of roughly the same dynamics to stiffen their fins for swimming.
Human Activity has Polluted European Air for 2000 Years, Study Finds
A new study combining European ice core data and historical records of the infamous Black Death pandemic of 1349-1353 shows metal mining and smelting have polluted the environment for thousands of years, challenging the widespread belief that environmental pollution began with the Industrial Revolution in the 1700s and 1800s.
UT Study Shows Virus Infection May be Linked to Toledo Water Crisis
In August 2014, toxins from algal blooms in Lake Erie shut down the city of Toledo, Ohio’s water supply, leaving half a million residents without potable water for more than two days. A new study co-authored by UT researchers shows that a virus may have been involved in the crisis and suggests methods for more stringent monitoring of water supplies.
Steven Wilhelm, Kenneth and Blaire Mossman Professor of Microbiology, along with UT graduate students Joshua Stough and Lauren Krausfeldt, worked with a team of 25 researchers to examine the physiological traits of Microcystis, the cyanobacterial organism responsible for scum-like algal blooms in Lake Erie. They found that it was consistent with algal blooms from 2012 and 2013 except for one thing—the Microcystis cells had a viral infection. Typically, toxins from algal blooms are trapped within the cell until the cell dies. But virus infections can cause cells to break open, leaking the toxin into the water and subsequently into water facility intake pipes and treatment centers.
Cold conversion of food waste into renewable energy and fertilizer has 'enormous potential'
Researchers from Concordia’s Department of Building, Civil and Environmental Engineering (BCEE) in collaboration with Bio-Terre Systems Inc. are taking the fight against global warming to colder climes.
Their weapon of choice? Cold-loving bacteria.
In a study published in Process Safety and Environmental Protection, authors Rajinikanth Rajagopal, David Bellavance and Mohammad Saifur Rahaman demonstrate the viability of using anaerobic digestion in a low-temperature (20°C) environment to convert solid food waste into renewable energy and organic fertilizer.
