This New Year’s Eve episode isn’t about resolutions — it’s about a reset.
In Still Curious: A New Year’s Reset (Without Resolutions), Heather reflects on a difficult year for science, public health, and trust, and makes the case for curiosity as a quieter, steadier way forward. Rather than focusing on optimism or big promises, this episode explores what it means to pause, to stay engaged without burning out, and to carry curiosity into the new year even when certainty feels loud.
The episode closes with a gentle midnight mantra for anyone listening alone, early, or in need of calm at the turn of the year.
