How life keeps time: Zeitgebers, hidden clocks, and ugh daylight savings
Not a fan of daylight savings? Beyond the depressingly early sunsets, that may be because it’s messing with your circadian clock. In this episode of Tiny Matters, we ask, “How do organisms — from bacteria to sea anemones to humans — keep track of time?” We talk about circadian clocks and how both internal molecular changes and environmental cues called “zeitgebers,” which include things like light and food, synchronize biological rhythms and help all of us survive.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

[BONUS] Polar bear fact vindication and vibrating insects: Tiny Show and Tell Us #36
In this episode of Tiny Show and Tell Us, we read an email from a listener who, as a kid, shared a fun fact with her classroom: polar bears have black skin. Her teacher not only told her she was wrong but embarrassed her in front of the other students. Well, it’s time to set the record straight. Polar bears do, in fact, have black skin and we do, in fact, love a grudge and are so glad to provide vindication. Then we talk about the hidden world of insect vibrational communication.We need your stories — they're what make these bonus episodes possible! Write in to [email protected] *or fill out this form* with your favorite science fact or science news story for a chance to be featured.A transcript and references for this episode can be found at acs.org/tinymatters.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Sobre Tiny Matters

Science shapes every part of our lives, but so much of its influence is overlooked or buried in the past. Tiny Matters is an award-winning podcast about tiny things — from molecules to microbes — that have a big and often surprising impact on society. From deadly diseases to forensic toxicology to the search for extraterrestrial life, hosts and former scientists Sam Jones and Deboki Chakravarti embrace the awe and messiness of science and its place in history and today, and how it could impact our world’s future. New episodes every Wednesday. Tiny Matters is brought to you by the American Chemical Society, a non-profit scientific organization based in Washington, D.C., and is produced by Multitude.
