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 “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.

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 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. 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
