    The Turnaway Study: What The Research Says About Abortion May 09, 2022

    A leaked draft opinion in the Supreme Court case Dobbs v. Jackson Women's Health Organization has placed uncertainty on the future of abortion rights in the United States. As written, the opinion would overturn Roe v. Wade protections. We at Short Wave were immediately curious about the data behind abortions: What happens when pregnant people are denied abortions?
    For answers, we turned to Dr. Diana Greene Foster, the lead researcher on the interdisciplinary team behind The Turnaway Study. For over a decade, she and her fellow researchers followed just under a thousand women who sought an abortion across 21 states. These data may give us insight into pregnant people's lives in a post Roe v. Wade United States.

    Planet Money: How Manatees Got Into Hot Water Apr 12, 2022

    Today we share the mic with our colleagues at Planet Money to talk about one of our favorite aquatic creatures: manatees. Decades ago, manatees nearly went extinct as their habitat dwindled and boats threatened their lives. But power companies noticed something: manatees were hanging out near their power plants, seeking out warm water. So, the power companies teamed up with environmentalists to turn the warm waters near power planets into manatee refuges — saving manatee lives and the power companies money in the process. Now, there's a new conundrum: manatees that are hooked on fossil fuels.


    Lemurs Will Rock You Apr 11, 2022

    Should Big Oil Pick Up The Climate Change Bill? Feb 02, 2022

    The Fourth Circuit Court of Appeals is deciding whether a Baltimore case against more than a dozen oil and gas companies will be heard in state or federal court. The city argues the companies are liable for the local costs of climate change. It wants the case heard in state court, which is governed by robust consumer protection laws. But industry lawyers are fighting hard to have it and more than 20 other similar lawsuits nationwide tried in federal court, where the oil and gas industry may be more likely to prevail.
    NPR climate correspondent Rebecca Hersher, brings an update on the case, which went before the U.S. Supreme court last year. She explains how this pending decision may prove key to determining who pays for climate change.

    Omicron Ebbing Gives Time to Boost Vaccinations Feb 01, 2022

    As COVID-19 cases in the U.S. drop, the hospitalization rate remains high — as does the death rate. Experts say getting a COVID vaccine booster is key to maintaining immunity, but only about half of all vaccinated people in the U.S. have gotten the booster, which increases protection against both serious illness and death from the Omicron variant. Still, many infectious disease experts are cautiously optimistic for the coming months, pointing to it as a time to bolster our defenses against the virus.

    The Debate About Pablo Escobar's Hippos Jan 14, 2022

    Pablo Escobar had a private zoo at his estate in Colombia, with zebras, giraffes, flamingoes - and four hippopotamuses. After Escobar was killed in 1993, most of the animals were relocated except for the so-called "cocaine hippos." Authorities thought they would die but they did not and now, about a hundred roam near the estate. Conservationists are trying to control their population because they worry about the people and the environment. But some locals like the hippos and a few researchers say the animals should be left alone and are filling an ecological void. The controversy reflects growing debate in ecology about what an invasive species actually is.

    Using Math To Rethink Gender (encore) Dec 01, 2021

    Gender is infused in many aspects of our world — but should that be the case?
    According to mathematician Eugenia Cheng, maybe not. In her new book, x+y, she challenges readers to think beyond their ingrained conceptions of gender. Instead, she calls for a new dimension of thinking, characterizing behavior in a way completely removed from considerations of gender.
    Cheng argues that at every level — from the interpersonal to the societal — we would benefit from focusing less on gender and more on equitable, inclusive interactions, regardless of a person's gender identity.

    An ode to the Pacific lamprey Oct 21, 2021

    Pacific lamprey may have lived on Earth for about 450 million years. When humans came along, a deep relationship formed between Pacific lamprey and Native American tribes across the western United States. But in the last few decades, tribal elders noticed that pacific lamprey populations have plummeted, due in part to habitat loss and dams built along the Columbia River. So today, an introduction to Pacific lamprey: its unique biology, cultural legacy in the Pacific Northwest and the people who are fighting to save it.
    To learn more about tribal-led efforts to restore the lamprey, read the Tribal Pacific Lamprey Restoration Plan and watch the documentary The Lost Fish.

    The Toll Of Burnout On Medical Workers — And Their Patients Oct 04, 2021

    Burnout has long been a problem among health care workers. The pandemic has only made it worse. Some were hopeful COVID vaccines would provide some relief, but that hasn't been the case. Now, health care workers are leaving the industry — and they're taking their expertise with them. Plenty of surveys say that burnout hurts patient care. NPR correspondent Yuki Noguchi spoke to medical workers who agree, the burnout they see on the job means that sometimes patients are not getting what they need.

    SURPRISE! It's A...Babbling Baby Bat? Oct 01, 2021

    A paper published recently in the journal Science finds similarities between the babbling of human infants and the babbling of the greater sac-winged bat (Saccopteryx bilineata) — a small species of bat that lives in Central and South America. As science correspondent Geoff Brumfiel reports, the researchers believe both bats and humans evolved babbling as a precursor to more complex vocal behavior like singing, or, in the case of people, talking.

    Scientists Are Racing To Save Sequoias Sep 28, 2021

    Based on early estimates, as many as 10,600 large sequoias were killed in last year's Castle Fire — up to 14% of the entire population. The world's largest trees are one of the most fire-adapted to wildfires on the planet. But climate change is making these fires more extreme than sequoias can handle. It's also worsening drought that is killing other conifer trees that then become a tinder box surrounding the sequoias, reports climate correspondent Lauren Sommer. Scientists warn that giant sequoias are running out of time and they're racing to save them.

    FEMA Has An Equity Problem Jul 01, 2021

    When a disaster like a hurricane or wildfire destroys a house, the clock starts ticking. It gets harder for sick people to take their medications, medical devices may stop working without electricity, excessive temperatures, mold, or other factors may threaten someone's health. Every day without stable shelter puts people in danger.
    The federal government is supposed to help prevent that cascade of problems, but an NPR investigation finds that the people who need help the most are often less likely to get it. NPR climate reporter Rebecca Hersher explains.

    The CDC Doesn't Know Enough About Coronavirus In Tribal Nations Sep 28, 2020
    A recent CDC report estimates Native Americans and Alaskan Natives are 3.5 times more likely to get COVID-19 than white people, and those under 18 are more likely to test positive.
    This report is the first time the federal government has released hard numbers on the coronavirus in tribal nations, but it is most notable for what it does not say about how the virus is affecting Native Americans and Alaskan Natives. And some scientists believe that the CDC's current numbers are an underestimate.
    Jourdan Bennett-Begaye, reporter and deputy managing editor of Indian Country Today, explains why the CDC data is so limited in scope — and her efforts to bring more data transparency to the table.

    Managing Wildfire Through Cultural Burning Sep 09, 2020

    Fire has always been part of California's landscape. But long before the vast blazes of recent years, Native American tribes held controlled burns that cleared out underbrush, encouraged new plant growth, and helped manage wildfires. It's a tradition that disappeared with the arrival of Western settlers. NPR climate correspondent Lauren Sommer explains how tribal leaders are trying to restore the practice by partnering up with state officials who are starting to see cultural burns as a way to help bring extreme wildfires under control.

    Understanding Unconscious Bias Jul 15, 2020

    The human brain can process 11 million bits of information every second. But our conscious minds can handle only 40 to 50 bits of information a second. So our brains sometimes take cognitive shortcuts that can lead to unconscious or implicit bias, with serious consequences for how we perceive and act toward other people. Where does unconscious bias come from? How does it work in the brain and ultimately impact society?
