Nose's response to odors more than just a simple sum of parts
Based on highly sensitive recordings of neuron activity in the noses of mice, researchers from Kyushu University have found that olfactory sensory neurons can exhibit suppression or enhancement of response when odors are mixed, overturning a long-standing view that the response is a simple sum with more complex processing only happening at later stages.

Falling
There are so many ways to fall–in love, asleep, even flat on your face. This hour, Radiolab dives into stories of great falls.  We jump into a black hole, take a trip over Niagara Falls, upend some myths about falling cats, and plunge into our favorite songs about falling.
