The reporting in audio and video — the same sourced investigations, in another format. New episodes weekly.
They're in rain, blood, and drinking water on every continent. We unpack what makes PFAS nearly indestructible, why the health science moved so fast, and what the new EPA limits actually change.
Watch & listen →A credit card's worth of plastic a week — or a myth? We separate the viral statistic from the peer-reviewed reality, and look at where microplastics actually come from and what the science can and can't yet say.
When the sky turns orange, the danger isn't the smell — it's PM2.5, particles small enough to cross from your lungs into your bloodstream. We trace how wildfire smoke travels a thousand miles and what actually protects you.
A residential tower comes down in the middle of the night with almost no warning. We reconstruct how corrosion, water intrusion, and years of deferred decisions can end in sudden structural failure — and what the warning signs looked like.
Thousands of American workers die on the job every year, and most never make the news. We look behind the statistic at what actually kills people at work, why the same failures repeat, and what 'preventable' really means.
A single overlooked detail — a gusset plate too thin, a design margin too slim — can bring down an entire span in seconds. We examine the engineering idea of 'fracture critical' and why America's aging bridges keep the phrase alive.
A train derails, tank cars rupture, and a town is told it's safe to go home. We break down how officials actually assess a chemical release, what 'below the limit' means in that moment, and where the uncertainty really lives.
