That peppery leaf in your salad has a compound called erucin that researchers are studying against one of the deadliest breast cancers.

In this episode we break down the 2023 Naples study that tested erucin on triple-negative breast cancer cells — what it found, and the big caveats — plus arugula's nitrate story and what the blood pressure research actually shows.

No miracle claims, just what the studies found and what they didn't.

Fish oil is one of America's best-selling supplements — and millions take it hoping to protect their memory. This summer, USC researchers ran the hardest test of that idea yet: two years, 365 older adults, a high daily dose of DHA, and spinal-fluid measurements proving the supplement actually reached the brain.

In this episode, we break down an elegant scientific failure — what the trial proved, what it didn't, and why eating fish and swallowing fish oil are two very different bets.

Three scientists just won the 2026 Nobel Prize in Physiology or Medicine for figuring out how to flip brain cells on and off with flashes of light. In this episode, we trace the story from pond algae to a Nobel stage — the light-sensitive protein channelrhodopsin, the mouse whiskers that twitched on command, and why optogenetics transformed neuroscience. Plus the honest caveats: what it can and can't do for humans yet, and where we'd draw the line between treatment and enhancement.
