This week, we're taking on your science brainteasers!  We find out why toothpaste ruins other flavours, whether humans have a mating season and why food goes in multicoloured, but comes out brown...  Plus, fighting Fido's fleas with fungus, stressed men take more risks, and predicting if hepatitis B will lead to liver cancer.  In Kitchen Science, we make a fruity fireball with orange peel.

How annoying to make quiet cars louder!

April Russell  asked the Naked Scientists:
I was listening to the show from July 7, and my immediate reaction was how annoying it would be to have nearly silent cars that we have to make louder. 

Perhaps having cars emit a continuous signal that can be picked up by a device held by the vision-impaired, and the proximity of the vehicle would change the sound they hear from the receiver (along the lines of echolocation for bats).  But thinking of this, I don't know if that would interfere with all the signals we have flying around these days, such as cell phones, satellite tv, radio, wireless internet..

On an unrelated note, I love listening to the show.  I don't have television or free time to watch things, but I can do a bunch of other things while listening to the podcast

I listen from the current episodes at home backward in time while at home, and from the beginning in 2000 forward in time from school, where I'm working toward my Masters of Applied Science. 

Thanks for the podcast!
