Like pushing a child on a swing, successive pushes can build up to a large oscillation, amplifying the sound. In addition, different hair cells amplify different frequencies, so this mechanism could create ...

What makes a fast racehorse?

... horse's leg restricts how quickly it can transmit force to the ground and bounce back up again and also increases the chances of injury. The team has also found that fast horses can bring their legs forward quickly in preparation for the next stride but that this is more difficult and therefore slower for...

The mechanism of communication between slow and fast twitch cells is unknown, but it is likely, the authors write, that similar examples will be found in other types of tissues. The findings describe "how fast muscle...
