Summary

Helping us tune into the science of sound this week is Bob Carlyon, who explains how we hear, how we can concentrate on one voice in a noisy room, and what it sounds like to have a cochlea implant. From the hard of hearing to the most finely tuned ears on the planet, Ian Russell describes how the greater moustached bat catches prey in complete darkness while flying at 40 miles per hour, Trevor Cox turns the sound of breaking wind into a record breaker as he talks about the biggest ever whoopee cushion, and in Kitchen Science, Derek and Dave investigate the science of balance with the help of a...

0:00.0	Stripping down science, the naked scientists.
0:07.0	Hello, welcome to this week's edition of The Naked Scientists with me, Chris Smith, and with Cat Arnie.
0:12.0	Hello. Now, coming up this week, it's... with Catani. Arnie.
0:13.0	Hello.
0:14.0	Now coming up this week it's life gym, but not as we know it because scientists have discovered
0:18.2	bacteria millions of years old living underground and they're thriving on nothing more than just radiation.
0:24.0	Also how boosy fruit flies are teaching scientists about how alcohol
0:28.0	switches certain genes on and off, that's coming up shortly, and we're listening to cancer.
0:32.0	Scientists have discovered how to detect cancer cells which are lurking in a blood sample
0:36.0	just by using sound to detect them.
0:38.0	Cat. And this week on the show we are joined by some very special guests to explore the science of sound, including how and why
0:45.0	researchers have done this.
0:47.0	Absolutely charming.
0:53.0	Anyway, they've built the world's biggest whoppy cushion,
0:56.0	and Salford University's Trevor Cox will be joining us to explain just why.
1:00.0	We're going to be hearing how bats use ultrasound to find their way around and
1:03.8	Ian Russell from Sussex University will be introducing us to the rather fantastically
1:08.3	named greater moustached bat that can fly at 40 miles an hour through a forest without hitting a single
1:13.9	thing and can still catch tiny insects just millimeters in length. And we're joined
1:18.6	in the studio here by Bob Carl Lyon, who's here to explain the workings of
1:22.1	the next generation of hearing aids
1:23.9	called cochlear implants to explain what happens when we all go death later.
