Deep-sea mussels still show biological rhythms tracking sunlight, tides

Posted on July 24, 2020 by Amy McDermott

Like many land animals, marine organisms follow daily and seasonal clocks—in the water, those clocks are set by the cadence of the sun and the moon. But researchers hadn’t known if deep-sea creatures also exhibit biological rhythms, tucked away in … Continue reading →

Journal Club: Tracing light’s effect on mood and learning in mice from the eye to deep within the brain

Posted on October 11, 2018 by Carolyn Beans

To the mammalian eye, light offers more than just sight. “Light is so important for many innate functions,” says neuroscientist Samer Hattar of the National Institute of Mental Health (NIMH). “We really don’t appreciate the importance of light in our … Continue reading →

Journal Club: Timed treatment fends off hardening of arteries in mice

Posted on June 15, 2018 by Charlotte Schubert

Timing is everything—including, possibly, when treating cardiovascular disease. By administering a drug-like compound in mice at a certain point during the circadian cycle, researchers were able to slow atherosclerosis while minimizing side effects, according to a recent study in Cell … Continue reading →

Journal Club: Fruit flies’ internal circadian clocks continually check the temperature

Posted on March 2, 2018 by Amber Dance

As a fruit fly sails from sunshine into a patch of shade, its temperature drops by 10 degrees F or so. Immediately, certain neurons in its brain spring into action, telling the fly’s circadian clock about the temperature change. By … Continue reading →

Journal Club: Phosphorylation has surprisingly big role in control of circadian clocks

Posted on February 2, 2017 by Jessica P. Johnson

The network of molecules that makes up the circadian clock, which governs the timing of cellular processes in most living things, has been well studied. But thus far, technological limitations have prevented researchers from elucidating exactly how the clocks orchestrate … Continue reading →
