We Need To Talk About Bird Poop
Seabird poop—sometimes called guano—was the “white gold” of fertilizers for humans for millennia. Rich in nitrogen and phosphorus from birds’ fish-based diets, the substance shaped trade routes and powered economies until chemical fertilizers replaced it.
But while people may no longer find bird poop profitable, these same poop deposits—often found on islands or coasts where the birds nest and rear their young—may also be nurturing ecosystems that would be left high and dry if the birds were to disappear. As seabird populations quickly decline, that’s becoming an increasing risk.
Australian researchers Megan Grant and Jennifer Lavers talk to Ira about the under-appreciated role of bird guano in ecosystems, and why scientists should be looking more closely at the poop patterns of endangered seabirds.
Sweating Is Our Biological Superpower
Sweat may feel like a constant summer companion, whether or not you exercise frequently. Being damp can feel uncomfortable, but the smells that follow—thanks to the lives and deaths of sweat-munching bacteria—are often socially stigmatized as well. (Deodorant itself is actually a very recent invention!)
But sweat isn’t just a cosmetic embarrassment: It’s crucial to keeping us cool, as the evaporating liquid pulls heat energy from our bodies. If you look at animals that don’t sweat, many have evolved alternate adaptations like peeing or even pooping on body parts to achieve that vital evaporative effect. People who are born unable to sweat run a constant risk of heatstroke.
Ira talks to Sarah Everts, author of the new book, The Joy Of Sweat, about what makes sweat useful, the cool chemistry of this bodily fluid, and why it’s our evolutionary superpower.
From Zero To 100 Butts: The Wild World Of Invertebrate Behinds
Recently, the staff of Science Friday came across a tweet that caught our attention, sent out by researcher Dr. Maureen Berg. Turns out, it was a call to source comic ideas for Invertebrate Butt Week, a celebration of—you guessed it—the butts of invertebrates. “Invertebrates really get the short end of the stick,” says Rosemary Mosco, the creator of the comic series Bird And Moon and #InverteButtWeek organizer. “People are not as excited about them as, say, a majestic whale or a beautiful bird. And I love my birds, but [invertebrates have] such an incredible diversity. So, butts are sort of a cheeky way to access some of that amazing diversity and celebrate it.”
Rosemary and other scientists and illustrators teamed up to create #InverteButtWeek, a celebration of the behinds of the backbone-less. “It’s a chance for some people who do science communication to do the silliest thing that they can possibly think of,” says Dr. Ainsley Seago, curator of invertebrate zoology at the Carnegie Museum of Natural History.
Science Friday’s D Peterschmidt talks to the organizers of #InverteButtWeek about how it came together, their favorite invertebrate butt facts (like how sea cucumbers have anal teeth), and how you can participate in the celebration.

Folge vom 01.07.2022Summer Science Books, Effect of Roe on Obstetric Care, Female Athletic Injuries. July 1, 2022, Part 2How Will Doctors Train For A Post-Roe World? It’s been one week since Roe v Wade was overturned by the Supreme Court. Many people are still wrapping their heads around what this overturn means for their states— and for their lives. For physicians and medical professionals, there’s another level of fear and concern about what practicing in a world without Roe v. Wade will mean. Questions are circulating about how training for OB/GYN’s may change, or if abortion care will stop being taught in medical school in states that do not allow the practice. For years, the American Congress of Obstetricians and Gynecologists has warned that a shortage of gynecologists will persist, and many in the industry fear the overturn will exacerbate this issue. Joining Ira to talk about how the Roe overturn could impact training of medical professionals is Dr. Maria Isabel Rodriguez, associate professor of obstetrics and gynecology at Oregon Health and Science University in Portland, Oregon. Why Are Female Athletes At A Higher Risk Of ACL Injuries? During 2021’s NCAA March Madness tournament, photos and videos from inside the athletes’ weight rooms went viral. The images showed the difference between what was available to the men’s and women’s teams. The men’s weight room was chock full of fitness training devices. For the female athletes, the only weights were six pairs of dumbbells. This was just one example of a harmful stereotype that has persisted about women in sports: strength training is for men, not for women. This kind of thinking is not only wrong, but can have serious consequences. Research shows female athletes are more prone to certain injuries, most strikingly ACL injuries. Women and girls are up to six times as likely to get an ACL injury compared to boys and men. Joanne Parsons, physical therapist and associate professor at the University of Manitoba, says, “A high school girl who plays basketball or soccer for one season, so let’s say three to four months-ish, will have a 1% chance of rupturing their ACL.” Parsons and her colleague Stephanie Coen, health geographer and associate professor at the University of Nottingham, UK, join Ira to talk about how the way athletic training works now puts women and girls at a disadvantage, and what can be done to better protect athletes.

Folge vom 01.07.2022SCOTUS Restricts EPA, Scientist Rebellion Protests, Kansas Wheat Problems, Early Science Films. July 1, 2022, Part 1Supreme Court Limits EPA’s Greenhouse Gas Regulating Ability This week, in its final round of opinions for the term, the U.S. Supreme Court ruled that Congress had not explicitly given the Environmental Protection Agency the power to regulate carbon dioxide emissions from power plants under the terms of the Clean Air Act. “Capping carbon dioxide emissions at a level that will force a nationwide transition away from the use of coal to generate electricity may be a sensible ‘solution to the crisis of the day.’ But it is not plausible that Congress gave EPA the authority to adopt on its own such a regulatory scheme in Section 111(d). A decision of such magnitude and consequence rests with Congress itself, or an agency acting pursuant to a clear delegation from that representative body,” wrote Chief Justice Roberts in the majority opinion in the case, West Virginia v. EPA. The ruling could hinder efforts globally to combat climate change, and could also affect regulations issued by other federal agencies dealing with "major questions" that would dramatically affect the economy. Timothy Revell, deputy U.S. Editor at New Scientist, joins Ira to talk about the decision and other stories from the week in science, including new studies of the canine evolutionary tree, a look back at 10 years of the CRISPR gene-editing technique, the launch of the CAPSTONE mission, and what our nose can tell us about potential relationships. The Scientist Rebellion: “We’re Not Exaggerating” About The Climate Crisis Earlier this year, more than 1,000 scientists in 26 countries risked arrest during protests against climate change inaction. In Washington D.C., Rose Abramoff and other demonstrators chained themselves to the White House fence before being arrested. Across the country, Peter Kalmus chained himself to the doors of a JPMorgan Chase & Co. Bank in Los Angeles and gave an impassioned speech: “The scientists of the world are being ignored. And it’s got to stop. We’re going to lose everything. And we’re not joking. We’re not lying. We’re not exaggerating.” Just recently, the Supreme Court recently cut the Environmental Protection Agency’s power (EPA) to regulate carbon emissions, a major step back in the climate movement. Abramoff, a global change ecologist based in Knoxville, Tennessee, and Kalmus, a climate scientist at NASA's Jet Propulsion Lab based in Los Angeles, California, are members of an international group of scientists called Scientist Rebellion, who committed to sounding the alarms about the climate crisis. They join Ira to talk about the state of the climate movement, what it’s like to be a climate activist in the United States, and the power of disruption. Drought In Western Kansas Exacerbates Global Wheat Shortage Russia's war in Ukraine has disrupted global food supplies, driving up demand and prices for wheat. But after months of drought, many western Kansas farmers won’t have a crop to sell. This time of year, the wheat growing in this part of western Kansas should be thigh-high and lush green.But as a months-long drought continues to parch the region, many fields tell a different story. “There’s nothing out there. It’s dead,” farmer Vance Ehmke said, surveying a wheat field near his land in Lane County. “It’s just ankle-high straw.” Across western Kansas, many fields planted with wheat months ago now look like barren wastelands. The gaping spaces between rows of brown, shriveled plants reveal hardened dirt that’s scarred with deep cracks from baking in the sun. Of all the years for drought to hit western Kansas wheat farmers, it couldn’t have come at a worse time. Even with wheat selling for near-record-high prices as the war in Ukraine disrupts the world’s food supplies, a lot of farmers in western Kansas won’t have any to sell. And those who made it through the drought with enough crop to harvest will likely end up with far fewer bushels than they had last year, a downturn that limits the state’s ability to help ease the global food crisis.

But when’s the last time you saw people clamoring for seats for an educational film made by scientists? The answer is likely never. But this was not unusual in the early 1900s, when film was an up-and-coming medium and science was capturing the public’s imagination. This summer, the Museum of the Moving Image (MOMI) in Queens, New York, is highlighting science education films of the past in the new exhibit “Twitch, Pop, Bloom: Science in Action.” SciFri producer Kathleen Davis speaks to Sonia Epstein, MOMI’s associate curator of science and film, about how these early videos and research went hand-in-hand at the dawn of cinema, and the historical significance of some of the videos in the exhibit.

Folge vom 24.06.2022HIPAA Explained, Trans Research, Queer Scientists. June 24, 2022, Part 2What Does HIPAA Actually Do? HIPAA, the Health Insurance Portability and Accountability Act, is name dropped a lot, but frequently misunderstood. Many are surprised to find that the “P” stands for portability, not privacy. Misunderstandings about what’s protected under the law go way deeper than its name. The law outlines protections only for health information shared between patients and health care providers. This means that any personal health data shared with someone who is not specifically mentioned in the law is not covered. If a period tracking app shares personal health information with Facebook, that’s not a violation of HIPAA. Neither is asking for someone’s vaccination status. Guest host Maddie Sofia talks with Tara Sklar, professor of health law and director of the Health Law & Policy Program at the University of Arizona, to explain what’s actually covered under HIPAA. “Research By Us And For Us”: How Medical Research Can Better Serve Trans Communities Trans medical care isn’t new or experimental, and study after study has shown that transition-related procedures—such as hormone therapies and surgeries—are incredibly safe and effective. But most long-term studies on trans health focus on the first few years after transitioning, leaving unanswered questions about the years after. Similar to members of other marginalized groups, trans people have long been treated like “case studies,” rather than potential experts when it comes to scientific research. So while researchers have studied trans bodies for decades, they haven’t always asked trans people what they need to know about their own bodies, such as: If I’m pursuing medical transition, how will my bone density change after years of taking estrogen? If I take testosterone, will I also need to get a hysterectomy? How will my hormonal and surgical options affect my fertility? Now, a new wave of medical research—led by trans medical experts themselves—is trying to fill in those blanks and address the needs of trans communities. Guest host Maddie Sofia speaks with Dr. Asa Radix, the senior director of research and education at Callen-Lorde Community Health Center, and Dallas Ducar, nurse practitioner and founding CEO of Transhealth Northampton. They talk about the state of research on trans health, and how studies can better address the needs of the trans and gender diverse communities. Food Pantry Venison May Contain Lead Iowa requires warning labels about the possible presence of lead in shot-harvested venison. Kansas, Missouri and Nebraska do not. A walk-in freezer about two stories high sits in one corner of a warehouse owned by a food bank called Hawkeye Area Community Action Program Inc. in Hiawatha, Iowa. Chris Ackman, the food bank’s communication manager, points to the shelving racks where any donated venison the organization receives is typically stored. Known as the Help Us Stop Hunger, or HUSH, program, the venison is donated by hunters from around the state, and Ackman says the two-pound tubes of ground meat go pretty quickly, lasting only a few months. “It’s a pretty critical program, I think, because there are a lot of hunters in Iowa,” he said. “And, it’s well enjoyed by a lot of families as well.” Similar programs around the country have been applauded as a way for hunters to do something they enjoy while also helping feed those in need. Iowa hunters donate around 3,500 deer a year through the program. From the hunters, the deer goes to a meat locker, where it’s ground, packaged and shipped off to food pantries around the state. But before it hits the shelves, Iowa officials require a warning label on the venison package. The label reads: “Lead fragments may be found in processed venison. Children under 6 years and pregnant women are at the greatest risk from lead.” Then, in bold type, the label notes: “Iowa has not found cases of lead poisoning from lead in venison,” along with a number to call for more information. Iowa stands out among Midwestern states in requiring a label warning about the potential hazard of lead ammunition and the fragments it can leave behind in shot-harvested game meat like venison. Donated venison in Kansas, Missouri and Nebraska come with no similar warning label. Read more at sciencefriday.com. Museum Exhibit Celebrates Queerness In Science Last year, the California Academy of Sciences debuted “New Science: The Academy Exhibit,” which celebrates 23 incredible LGBTQIA+ scientists. The folks in this exhibit are challenging the exclusionary practices that are all too common in scientific spaces, with the aim of creating a more inclusive and welcoming environment. It is a celebration of queerness in science. Guest host Maddie Sofia talks with the curator of this exhibit, Lauren Esposito, who is a curator of arachnology at the California Academy of Sciences and founder of 500 Queer Scientists, based in San Francisco. They discuss the exhibit, the importance of LGBTQIA+ representation in STEM, and, of course, arachnids. The exhibit is free and open to the public at the California Academy of Sciences, and it is also available online.
