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.

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 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
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 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.

Folge vom 09.09.2022Remembering Frank Drake, History of Air Conditioning. Sep 9, 2022, Part 2The Hot And Cold Past Of The Air Conditioner In the Northeast, the leaves have started changing colors, heralding the season of pumpkins, sweaters, and the smell of woodsmoke. But in some parts of the country, the heat hasn’t let up. In cities like Dallas, Phoenix, and Miami, temperatures were up in the high 80s and low 90s this week—and with climate change, the U.S. is only getting hotter. But humans have come up with an ingenious way to keep the heat at bay: air conditioning. Widely considered one of the greatest engineering achievements of the 20th century, the technology has transformed how and where people live—and it’s prevented countless deaths. But it comes at a cost, and if we’re going to keep up with a warming climate, we’re going to need some other tricks to stay cool. Remembering Frank Drake, Who Listened To The Cosmos Last week, astronomer and SETI pioneer Dr. Frank Drake died at the age of 92. Dr. Drake was a key figure in the search for extraterrestrial intelligence—from Project Ozma in 1960, to the founding of the SETI Institute. He collaborated on the ‘Golden Record’ that Earth sent to the stars on board the Voyager space probes. Drake also created a mathematical way of estimating the probability of discovering signs of intelligent life, a calculation that became known as the Drake Equation, and spent years advocating for the search for alien life. Drake appeared on Science Friday many times over the years. Here, in excerpts from conversations recorded in 2010 and 2016, he talks with Ira about the search for extraterrestrial intelligence, and his role with the Voyager Golden Record project. Our condolences to his family, friends, and colleagues. Transcripts for each segment will be available the week after the show airs on sciencefriday.com. Subscribe to this podcast.

Folge vom 02.09.2022New COVID Vaccines, “Nope” Creature, NJ Toxic Site, Germicidal Coating. Sep 2, 2022, Part 1New, Extra Protective COVID Vaccines Are On The Way Earlier this week, the FDA approved brand new COVID-19 vaccines from both Moderna and Pfizer-BioNTech that are designed to better protect people from the BA.4 and BA.5 omicron subvariants. At the same time, the U.S. is scaling back free testing and precautionary measures, putting more pressure on vaccines. Casey Crownhart, a climate and technology reporter at MIT Technology Review, joins Ira to talk about COVID updates and other science news of the week. They also discuss how the U.S. is bracing for a record-breaking heatwave, the devastating floods in Pakistan, how the city of Jackson, MI ended up without running water, why Greenland’s “zombie ice” is causing concern, a massive investment in solar power, and a clue as to how the Ancient Egyptians built the pyramids of Giza. New Jersey’s Lenape Nation Fights Ford’s Toxic Legacy The Turtle Clan of the Ramapough Lenape Nation has lived in the wooded hills around Ringwood for centuries, enduring the impacts of European settlement and the building up of America. But the toxic waste that now surrounds the Passaic County community is from an invasion of an entirely different kind. And it wasn’t long before residents started getting sick. When the federal government created the National Priorities List, better known as Superfund, in 1980, abandoned iron mines in Ringwood were among the first sites to be listed; they made the list in 1983. Between 1965 and 1974, the Ford Motor Company dumped hundreds of thousands of gallons of paint sludge, solvents and other waste into the mines scattered throughout the Turtle Clan’s homeland. By then, the southern portion of the site had been sold off by Ford to the Ringwood Solid Waste Management Authority, which went on dumping more waste onto and into the already toxic land. Arsenic and lead, benzene and 1,4-dioxane leached into groundwater. Kids played among slabs of hardened paint sludge. Adults scavenged the dump sites for copper and other valuable metals. Read the rest at sciencefriday.com. Coming Soon: A Germ-Killing Countertop? From restaurant tables to office door knobs, not to mention anything inside a hospital, the world is full of surfaces that need sanitizing, lest someone catch a surface-borne viral or bacterial infection like the flu or MRSA. The typical solution involves sanitizing those surfaces with sprays and fluid cleaners. Or, sometimes, using materials that are hostile to microbes, such as silver or copper. But a team of engineers at the University of Michigan has another solution in mind: a spray-on coating that combines the stabilizing power of polyurethane with the well-documented germicidal qualities of essential oils such as cinnamon, tea tree, and lemon. As the team reports in the journal Matter this week, their coating seems to kill pathogens like SARS-CoV2, MRSA and E. coli within minutes—and lasts for months before it must be refreshed. Research co-author Anish Tuteja joins Ira to talk about the innovation, and how he thinks it might be useful. The Surprising Animal Science Behind Jordan Peele’s ‘Nope’ One of the summer’s biggest blockbusters has been the alien horror film “Nope,” from director Jordan Peele. “Nope” has elements of many classic UFO films, with the Spielbergian charm of “Close Encounters of the Third Kind,” and the horror and destruction from “The War of the Worlds.” For the spoiler-averse, this is your warning to turn back now. The big twist in “Nope” that differentiates it from other alien films is that it isn’t a UFO hanging out in the skies above our main characters. The saucer-shaped figure is the alien itself. Writer and director Jordan Peele attributes much of the inspiration for the alien as coming from sea creatures. He enlisted the help of scientific consultants including marine biologist Kelsi Rutledge to help bring the creature, known in the film as Jean Jacket, to life. She even gave it a scientific name: Occulonimbus edoequus, meaning “hidden dark cloud stallion eater.” Kelsi, who is a PhD candidate at UCLA in Los Angeles, California, talks to Ira about the ingredients that went into creating a new creature to scare audiences.

Folge vom 02.09.2022When Life Begins, Open Access Research, Wasps. Sep 2, 2022, Part 2Why Is It So Hard To Agree On When Human Life Starts? After decades of deliberations involving physicians, bioethicists, attorneys, and theologians, a U.S. presidential commission in 1981 settled on a scientifically derived dividing line between life and death that has endured, more or less, ever since: A person was considered dead when the entire brain—including the brainstem, its most primitive portion—was no longer functioning, even if other vital functions could be maintained indefinitely through artificial life support. In the decades since, the committee’s criteria have served as a foundation for laws in most states adopting brain death as a standard for legal death. Now, with the overturning of Roe v. Wade and dozens of states rushing to impose abortion restrictions, American society is engaged in a chaotic race to define the other pole of human existence: When exactly does human life begin? At conception, the hint of a heartbeat, a first breath, the ability to survive outside the womb with the help of the latest technology? To read the full article, visit sciencefriday.com. Taxpayer-Funded Science Is Finally Becoming Public Last week, the White House Office of Science and Technology Policy announced a new directive requiring federally-funded science be made available to the public for free, and faster. Set to take effect by the end of 2025, the new rule would do away with the Obama-era policy that journals can keep research with taxpayer funding behind paywalls for up to one year. In addition, more kinds of research would qualify than previous policies have required. So how does freely accessible research benefit the people who pay for it—or the scientists who do the work itself? Nobel Prize-winning medical researcher and open science advocate Harold Varmus joins Ira to discuss. Why You Should Thank Your Local Wasp It’s late in the summer, meaning any outdoor gathering with food and drink has a good chance of being visited by a pesky, buzzing wasp. But don’t reach for that rolled-up newspaper or can of bug spray. The wasps in your world play an important role that’s often overlooked. Far beyond the social hornets and yellowjackets people think about when they picture a wasp, the wasp world includes thousands of species. Some are parasitic, injecting their eggs into unwilling prey. Others hunt, either paralyzing prey for their young to feed on, or by bringing bits of meat back to a nest for their young. Some are strictly vegetarian, and live on pollen. Some are needed for the pollination of figs and certain species of orchids. Dr. Seirian Sumner, a behavioral biologist at University College London, says that if people understood the services provided by wasps the same way that they understand the need for bees, they might be more willing to overlook an occasional wasp annoyance—and might even be thankful for the wasps in their lives. In her book Endless Forms: The Secret World of Wasps, Sumner makes the case for wasps as nature’s pest control agents, as important pollinators that should be celebrated.
