How Grief Rewires The Brain
Being a human can be a wonderful thing. We’re social creatures, craving strong bonds with family and friends. Those relationships can be the most rewarding parts of life.
But having strong relationships also means the possibility of experiencing loss. Grief is one of the hardest things people go through in life. Those who have lost a loved one know the feeling of overwhelming sadness and heartache that seems to well up from the very depths of the body.
To understand why we feel the way we do when we grieve, <a href="https://www.sciencefriday.com/segments/book-the-grieving-brain/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">the logical place to turn is to the source of our emotions: the brain</a>. A new book explores the neuroscience behind this profound human experience.
Ira speaks to Mary-Frances O’Connor, author of The Grieving Brain: The Surprising Science of How We Learn from Love and Loss, a neuroscientist, about adjusting to life after loss.

Fish Make More Noise Than You Think
One of the most famous films of undersea explorer Jacques Cousteau was titled The Silent World. But when you actually stop and listen to the fishes, <a href="https://www.sciencefriday.com/segments/fish-noise/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">the world beneath the waves is a surprisingly noisy place</a>.
In a recent study published in the journal Ichthyology & Herpetology, researchers report that as many of two-thirds of the ray-finned fish families either are known to make sounds, or at least have the physical capability to do so.
Some fish use specialized muscles around their buoyancy-modulating swim bladders to make noise. Others might blow bubbles out their mouths, or, in the case of herring, out their rear ends, producing “fish farts.” Still other species use ridges on their bodies to make noises similar to the way crickets do, grind their teeth, or snap a tendon to sound off. The noises serve a variety of purposes, from calling for a mate to warning off an adversary.
Aaron Rice, principal ecologist in the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology in Ithaca, walks Ira through some of the unusual sounds produced by known fish around the world—and some mystery noises that they know are produced by fish, but have yet to identify.
