Allergies have been documented in historical records dating as far back as 2,400 years ago, when Hippocrates wrote about “hostile humors” in some people who suffered badly after eating cheese. But why do we experience them to begin with? What even is an allergy? Are allergies on the rise? And why are some mere nuisances, while others are deadly?This episode is a roundup of allergy stories—from the mundane to the frightful—and a round up of allergy questions we’re asking Dr. Theresa MacPhail, author of Allergic: Our Irritated Bodies in a Changing World, to answer for us.Featuring Beni Osei Duker, Theresa MacPhail, Dwayne Smith, and Lily Ko.Produced by Felix Poon. For a transcript and full list of credits, go to outsideinradio.org.Correction: An earlier version of this episode suggested that bee pollen and local honey could only be effective as a form of immunotherapy at the site of the allergy, i.e. in your nose. In fact, immunotherapy is commonly administered as a subcutaneous (under the skin) injection to treat nasal allergy symptoms. A more relevant reason why they don’t work as immunotherapy is that hay fever is caused primarily by wind-carried pollens rather than insect-carried pollens that bees gather, among other reasons. SUPPORTOutside/In is made possible with listener support.

Venom is full of dualities. According to the UN’s World Health Organization, snakebite envenoming causes somewhere between 81,000 and 138,000 deaths per year, and even that is likely an undercount. Yet research into venom has yielded treatments for diabetes, cancer, erectile dysfunction, and even the celebrity favorite diabetes slash diet drug, Ozempic. In this episode, we explore the world of venom, where fear and fascination go hand-in-hand, and the potential for healing comes with deadly stakes. This is part II of our “Things That Can Kill You” miniseries, which also explores poison and allergies.Featuring Sakthi Vaiyapuri.

A few months ago we got an email from a listener who tried a bit of a very poisonous apple and lived to tell the tale. Ultimately, he was fine, but the incident left him full of questions. We figured, why not run with that curiosity? We put a call out for all of your poison related queries and you delivered: How much should you worry about those green potatoes in your pantry? Could our car tires be poisoning the environment? It’s another Outside/Inbox roundup on the show this week. Buckle up. This is the first part of a “Things That Can Kill You” mini-series. Up next we tackle venom and allergies.Featuring Hussein Elgridly, Deborah Blum, Andy Robinson, Angela Mech, Kyle Lombard and Heejung Jung.Are green potatoes toxic?Are invasive browntail moths expanding their range?Is hydroxyapatite an effective substitute for fluoride?How much toxic airborne pollution is contributed by vehicle tires?For our next Outside/Inbox roundup, we’re looking for questions about sound!

Sgt. Tibbs, a fluffy, 19-year-old Maine Coon with tiger stripes, soft eyes, and a chipped tooth, is missing on the streets of Manchester, New Hampshire. His owner, Rose, fears the worst. But when she finds out her cat was never missing at all – the truth turns out to be worse than she feared.From our friends over at the Document team at New Hampshire Public Radio, this is the first in a four-part series about what we owe our pets – and what we owe our neighbors.For full credits and transcript, visit outsideinradio.org.SUPPORTOutside/In is made possible with listener support.

After the Irish fought for and won their independence from the British in 1921, they had a problem. Centuries of exploitation had left the island one of the least forested nations in Europe, with less than 2% tree cover. So, they started planting a non-native American tree: fast-growing Sitka spruce capable of rebuilding their timber resources in record time. And it worked. Today, about 12% of the island is forested. But in the rural areas where iconic rolling hills have been replaced by rows and rows of conifers, farmers are not happy. Outside/In host Nate Hegyi takes us to County Leitrim, an area of Ireland hit hard by the Troubles and the Great Famine, to meet the townspeople who are fighting what they say is a new wave of colonialism: Sitka spruce plantations. Produced by Nate Hegyi.

Recently, our producer Justine Paradis noticed something. Humans really like to sing together in groups: birthday parties, sports games, church hymns, protest chants, singing along to Taylor Swift at the Eras concert… the list could get very long.But… why?

We’re used to seeing dogs and cats play with toys or get the zoomies… but do animals like rats and bumblebees play too? What is animal play for? How do scientists even decide what counts as play?Today, we’re taking a serious look at goofy behavior. We’ll discover the five-part checklist that many scientists use to recognize play in nature, and find out why taking turns is so important for healthy brain development. This episode is a collaboration between Outside/In and Tumble, the science podcast for kids. Featuring Junyi Chu and Jackson HamProduced by Lindsay Patterson, Marshall Escamilla, and Taylor Quimby.

In New Hampshire, the most beloved swath of public land is the White Mountain National Forest. People interact with it as they would a national park – hiking, swimming, camping, and more. But a national forest is NOT a national park. The difference comes down to a fundamental concept: the “multiple-use” land mandate. In the WMNF, you’ll find parts of the forest preserved for wildlife conservation, recreation, climate resilience, and, most controversially, logging. This episode looks at one patch of forest from three different perspectives: a conservationist who would like to see cutting halted in the WMNF, loggers who would like to see it ramped up, and the US Forest Service that has to somehow appease them both. Featuring Zack Porter, Jeremy Turner, Charlie Niebling, Jasen Stock, Jim Innes, and Luke Sawyer.SUPPORTTo share questions and feedback with Outside/In, call the show’s hotline and leave us a voicemail.
