## COVID-19’s Lingering Toll On The Heart
As new omicron-specific boosters against COVID-19 unroll in cities around the
US, research is revealing more about the longterm consequences of even one
infection with the SARS-CoV2 virus. Writing this week in Nature Medicine, a
team of researchers from Germany describe finding long-lasting signs of heart
disorders
in the majority of recovered patients in their study group–even up to nearly a
year later.
FiveThirtyEight’s Maggie Koerth joins Ira to describe the research and how it
fits into what we’re learning about the scope of Long Covid. Plus taking the
temperature of the melting Thwaites Glacier, new insights into the genes of
both immortal jellyfish and human astronauts, and a post-mortem of the world’s
first known amputation.

## Why Are Dead Fish Piling Up Across The San Francisco Bay?
Thousands of dead fish are piling up across the Bay Area.
From the concrete outer edges of Oakland’s Lake Merritt to the sandy beaches
of San Francisco’s Fort Funston and the pebbled banks of Oyster Point in San
Mateo County, the carcasses of fish likely poisoned by a harmful algal bloom —
more commonly known as a red tide — are washing ashore.
It’s a mass-death event the San Francisco Bay hasn’t seen the likes of in
years, says Jon Rosenfield, senior scientist with environmental group San
Francisco Baykeeper.
“From a fish’s point of view, this is a wildfire in the water,” he said.
By SF Baykeeper’s count, the number of fish dying off in the San Francisco Bay
could easily exceed hundreds of thousands, and that, Rosenfield said, might
even be a “low” estimate.
His field investigator confirmed “https://www.sciencefriday.com/segments/dead-fish-toxic-
algae/?utm_source=WNYC&utm_medium=&utm_campaign=&utm_content=" target="new">easily tens of thousands of fish
dead” in Lake
Merritt alone. But Rosenfield cautioned, “What you see is just the hint of
what’s actually happening further beneath the water’s surface and in places
you’re not getting to on the shoreline. So it’s really an uncountable number.”
It may be harmful to humans, too. An algal bloom of this size can cause skin
irritation and respiratory problems, and the San Francisco Bay Regional Water
Quality Control Board is advising people to avoid swimming, kayaking or other
activities on the water until the bloom subsides.

## As Temperatures Get Warmer, Fish Are At Risk
Climate change is expected to have a big effect on a sensitive group of
creatures: fish. A new study out of the University of Arkansas predicts that
there is likely to be a six-fold increase in large fish mortality events
between now and 2100, specifically in freshwater lakes in Minnesota and
Wisconsin.
Known as “summerkills” and “winterkills”, seasonal die-offs are a part of
fishy nature, but https://www.sciencefriday.com/segments/fish-at-
risk/?utm_source=WNYC&utm_medium=&utm_campaign=&utm_content=" target="new">have been happening at a greater frequency as temperatures
increase. That’s due to
climate change-related factors like algal blooms, infectious disease, and
oxygen deprivation.
Joining Ira to talk about the future for freshwater fish is Simon Tye, PhD
candidate in biology at the University of Arkansas in Fayetteville.

## As The World Decarbonizes, Sulfuric Acid May Be In Short Supply
A move towards more alternative energy sources and away from fossil fuel
production is a net positive for the world. But there’s an unanticipated side
effect—a possible global sulfuric acid supply shortage.
Eighty percent of the world’s sulfuric acid is the byproduct of fossil fuel
production. https://www.sciencefriday.com/segments/sulfuric-acid-supply-
shortage/?utm_source=WNYC&utm_medium=&utm_campaign=&utm_content=" target="new">Cutting back on coal, oil, and natural gas means producing less
sulfur acid. That’s
important as sulfuric acid is critical to making fertilizer, as well as green
technology like solar panels and batteries.
Ira talks with Mark Maslin, professor of Earth System Science at University
College London, about his latest research, which points to a looming sulfur
shortage.

## The New G.O.A.T Of Park Systems Is An Actual Goat
If you walk into a park, the odds are pretty high that you’ll find an invasive
plant species, like buckthorn, giant hogweed, or multiflora rose. These
resilient plants can often grow uncontrollably and out-compete native species
for resources, which has https://www.sciencefriday.com/segments/goats-park-invasive-
species/?utm_source=WNYC&utm_medium=&utm_campaign=&utm_content=" target="new">consequences for native
wildlife that depend
on other native plants. They can also be incredibly difficult to remove.
That’s why a growing number of parks across the United States are turning to
unlikely helpers: goats.
Conservation grazing is a practice in which livestock are used to maintain
biodiversity. Because goats eat almost everything, they chow down on invasive
plants and make them much easier to remove.
Radio producer Rasha Aridi speaks with Hillary Steffes, the chief goat herder
at Allegheny GoatScape in Pittsburgh, Pennsylvania, about using goats as a
conservation tool. Then, Rasha takes a trip to Riverside Park in NYC to meet
some goats, and talk with Marcus Caceres, a field supervisor at the Riverside
Park Conservancy.
