Researchers find wetland plant can filter PFAS chemicals

By Enrique Saenz, Indiana Environmental Reporter

Researchers have found that a common wetland plant native to Australia can remove toxic “forever chemicals” from the surrounding environment.

In a 190-day greenhouse experiment, a team of Chinese and Australian researchers found that Juncus sarophorus, a wetland plant also known as the broom rush, could tolerate and accumulate PFOS, PFOA and PFHxS, three of the most commonly studied PFAS chemicals.

Global warming may impact Great Lakes beaches

This article was republished here with permission from Great Lakes Echo.

By Yue Jiang, Great Lakes Echo

Global warming will produce more frequent high rainfall events in the Upper Great Lakes, according to a University of Guelph expert.

Rather than average water levels falling as previously assumed, it’s possible that the average will increase because of more precipitation, which will constrict the beach area, said emeritus professor Robin Davidson-Arnott of the Department of Geography, Environment & Geomatics.

PFAS is a widespread problem. The solution needs to come from widespread sources

PFAS research is still in the early stages, which means issues with PFAS crop up all the time to surprise researchers like Michigan State University professor Cheryl Murphy.

PFAS, per- and polyfluoroalkyl substances, are known as Forever Chemicals because of their reluctance to break down in humans. They can be in the food chain, drinking water and are found in common items in everyday commercial use like water-repellent clothing, dental floss and non-stick cookware.

Who caught the world’s largest muskie? Even the experts don’t agree

The largest known muskie is 67 pounds 8 ounces. Or it’s 69 pounds 11 ounces. Or it’s 70 pounds 10 ounces. Depending on the type of record, whom you ask or what organization you trust, it ­­could be any of those answers.

After Great Lakes Now published a column on muskies that referenced record sizes, it kicked off a dispute among readers on what record was the most accurate, so Great Lakes Now decided to do a deeper dive.

Lake heatwaves driven by human-caused climate change

Just like the atmosphere and the ocean, lakes can be subject to extreme spikes in temperature, and new research shows that the vast majority of these heatwaves over the past 25 years are the result of human-caused climate change.

Iestyn Woolway – a climate scientist at Bangor University in Wales – and his colleagues analysed satellite data of surface temperatures in lakes around the world, including the Great Lakes, to identify when and where heatwaves occurred since the satellites came online in 1995.

Scratching the surface: Regional research groups explore winter conditions of Green Bay, Great Lakes

María Hernández, a University of Chicago graduate student studying microbial ecology, was both nervous and eager to traverse a frozen Green Bay. Being sure to walk slowly and carefully, she assisted fellow researchers in extracting samples of ice-cold freshwater.

“We’re out here because we usually sample in the spring and summer,” said Hernández, “So this is the first time we’re going to be sampling in the winter, and it just gives us another view into what the microbes are doing at different times of the year.”

Hernandez and her University of Chicago colleagues were joined by University of Minnesota Duluth researchers on Monday for the recently launched “Winter Grab,” a first of its kind, week-long collection event for regional researchers studying Great Lakes’ winter conditions.

Cold Cover: Great Lakes ice forms after initial low percentage

A recent burst of cold weather has boosted Great Lakes ice coverage from initial projections that were well below historical average back to the typical range.

But the current levels still expose a long-term trend of overall declining coverage, scientists say.

“In terms of Great Lakes ice cover, we do see decline and reduced ice cover in recent decades,” Ayumi Fujisaki-Manome, assistant research scientist with the Cooperative Institute for Great Lakes Research, said in an interview with Great Lakes Now.

CHICAGO (AP) — Rowers, kayakers and other users of the Chicago River are getting a real-time look at one measure of water quality in the system that weaves through downtown and several neighborhoods.

Chicago nonprofit Current in 2019 installed three sensors in the river’s three main branches to continuously estimate the amount of bacteria from human and other warm-blooded animals’ waste.

Side by Side: The biggest challenge for birds is cohabiting with humans

North America has 3 billion fewer birds today than five decades ago, according to a recent scientific study.

That loss equates to more than a quarter of the continent’s entire bird population, and the research documenting the decline has shown that it may be worse than first realized.

Genetic mapping boosts hopes for restoring prized lake trout

By John Flesher, AP Environmental Writer

TRAVERSE CITY, Mich. (AP) — Scientists have traced the genetic makeup of lake trout, a feat that should boost efforts to rebuild populations of the prized fish in the Great Lakes and other North American waters where they’ve been hammered by invasive species, overfishing and pollution, officials said Tuesday.

Grayling Revival: Researchers hope to reintroduce a once-abundant native fish

Every year, Nicole and Tom Watson take a trip to Alaska. Like the typical tourist, they enjoy fly fishing and experiencing the untamed wilderness, yet their visit is no ordinary vacation. Among their duffel bags and backpacks, there’s a special piece of carry-on luggage: a carefully sealed container of fish eggs.

New theory: Earth’s longer days kick-started oxygen growth

By Seth Borenstein, AP Science Writer

Scientists have a new idea for how Earth got its oxygen: It’s because the planet slowed down and days got longer.

A study published Monday proposes and puts to the test the theory that longer, continuous daylight kick-started weird bacteria into producing lots of oxygen, making most of life as we know it possible.

Bacteria Cleanup: Should we let nature clean up oil spills?

Natural populations of oil-degrading bacteria could help to clean up freshwater rivers and lakes after spills from pipelines and trains, researchers have found after experiments that simulated spills in a Canadian lake.

Vince Palace, who led the work at the International Institute for Sustainable Development’s Experimental Lakes Area in western Ontario, said that the methods currently in use for cleaning up spills in rivers and lakes – mostly digging up and dumping contaminated soil – are not particularly effective.

Great Lakes algae threatens air quality

This article was republished here with permission from Great Lakes Echo.

By Hannah Brock, Great Lakes Echo

Toxins from harmful algal blooms are known to pollute water, but now researchers are looking at how they harm Great Lakes air.

And that also could have implications for human health, they say.

The Suckers: Great Lakes’ “best supporting fishes” are important to the food web

As an avid angler, Great Lakes Now Host Ward Detwiler has encountered suckers, a bottom-feeding family of fish that are present in all five Great Lakes and spawn in the rivers of the watershed.

But he’s never been terribly mindful of them.

“It’s never something you’re really out looking for,” Detwiler said.

Invasive Tracking: Researchers trying to trace zebra mussel infestations

While initial populations of invasive zebra mussels were brought to the Great Lakes on boats and in freighter ballast water, a new source of the invasive species has researchers concerned — pet stores.

The Minnesota Aquatic Invasive Species Research Center has partnered with the University of Minnesota Genomics Center to genetically trace zebra mussels that have been found in aquarium moss balls in pet stores.

Scientists: Pup births hopeful sign for Isle Royale wolves

By John Flesher, AP Environmental Writer

TRAVERSE CITY, Mich. (AP) — Wolf pups have been spotted again on Isle Royale, a hopeful sign in the effort to rebuild the predator species’ population at the U.S. national park, scientists said Monday.

It’s unknown how many gray wolves roam the island chain in northwestern Lake Superior.
