The friendly honk
Sound permeates the human experience and gets our attention, sometimes traumatically so.
Using body noise to improve cancer detection
In passive elastography, the elasticity of tissue is measured using the body's own propagation of shear waves, which enables more effective imaging deeper inside the body in an even more noninvasive way than traditional elastography and may be used for cancer detection.
Lending plants a hand to survive drought
A research team led by the Australian National University has found a new way to help plants better survive drought by enhancing their natural ability to preserve water.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies. This episode was produced with help from Molly Webster and Tracie Hunte. Support Radiolab today at Radiolab.org/donate.
