Invisible tattoo ink appears under UV light then vanishes
A new type of tattoo ink that becomes visible only under ultraviolet light and then disappears has been discussed in a Nature podcast briefing on 16 October 2026.
Podcast episode highlights the new ink
The Nature Briefing podcast released an episode on 16 October 2026 that features a discussion about this disappearing tattoo. Listeners can access the full conversation through Apple Podcasts, Spotify, YouTube Music, or other favorite podcast applications. An RSS feed is also available for those who prefer to subscribe via a newsreader.
Visual demonstration of the effect
The broadcast includes a specific segment where viewers watch the tattoo appear under ultraviolet light before it vanishes again. This visual example helps explain how the ink functions in real time during the presentation. The episode runs for approximately four minutes and fifteen seconds before moving to other scientific topics.
Other science topics covered later
After discussing the tattoo, the podcast shifts to an explanation of why large dogs age faster than small ones. Researchers suggest that rogue jumping genes might be responsible for this difference in aging rates between dog sizes. The briefing also encourages listeners to subscribe so they never miss future episodes of the show.
