Forever chemicals, also known as PFAS, are found in virtually every corner of the world, including in most people’s bodies. These synthetic compounds have been linked to a wide range of health issues — from infertility to cancer to neurological problems — even at low levels of exposure. In a new book, They Poisoned the World: Life and Death in the Age of Forever Chemicals, investigative journalist Mariah Blake lays out how these toxic chemicals became so ubiquitous. Blake spoke with Apple News In Conversation host Shumita Basu about a group of unlikely activists fighting back against those responsible and offers practical tips to protect yourself.

For the past few years, a campaign against sunscreen has been building — with social-media influencers claiming that sunscreen itself, rather than the sun, is damaging people’s skin and harming their health. The misinformation is working: More than 16 million adults have cut back or stopped using sunscreen because of it. Meanwhile, skin-cancer rates continue to rise. Brian Underwood, beauty and grooming director at Men’s Health and Women’s Health, joins Apple News In Conversation guest host David Greene to share his reporting on who’s driving this movement, the confusing FDA report that helped fuel it, and what it will take to restore trust in sunscreen.

Testosterone prescriptions are at an all-time high in the U.S., and according to a survey by Men’s Health, 70% of men say their levels of the hormone are important to them. This increased attention to T has even reached the Pentagon, which announced mandatory testosterone screenings for troops over the age of 30. Michael Andor Brodeur, a Men’s Health contributor and author of the book Swole, joins Apple News In Conversation guest host David Greene to explain how testosterone transformed from solely a medical treatment into a cultural obsession — and what that shift reveals about the pressures American men face today.

This summer, the U.S. saw its largest cyclospora outbreak on record — with more than 22,000 suspected cases linked to contaminated iceberg lettuce, alongside a wave of other foodborne illnesses. Timothy D. Lytton, a law professor at Georgia State University and author of Outbreak: Foodborne Illness and the Struggle for Food Safety, joins Apple News In Conversation host David Greene to explain how America’s food-safety system actually works, how the system evolved, and what recent outbreaks reveal about the changes needed to make us all safer.

Peak tick season is here — and the fastest-growing tick-borne illness in the country is alpha-gal syndrome, a condition that causes an often-severe allergy to red meat and other animal products. It’s primarily spread by lone-star ticks, once confined to the Southeast but now found as far north as Maine and Michigan. The syndrome can trigger a range of reactions — from hives to anaphylaxis — and at least one death has been attributed to it. New Yorker staff writer Burkhard Bilger, who has reported on the syndrome’s rise, joins Apple News In Conversation guest host David Greene to explain how it was discovered, why it can take years to diagnose, and how it’s reshaping the way people eat, work, and spend time outdoors.
