Summary

We reach for the skies on this week's Naked Scientists, with High Altitude Adventures. We find out how the body reacts to the low oxygen at high altitudes, and join Laura Soul testing the theories on a trek up to Everest base camp. Plus, we find out how the continental collisions that made mountains may have plunged the Earth into an ice age. We also hear how the rate of mutation changes in lab-bench evolution, how looming sounds make our vision more sensitive, why poking a stem cell can change its fate and the chemistry behind the taste of fizz. In Kitchen Science, we make a mountain... Like this podcast? Please help us by supporting the Naked Scientists

0:00.0	Boldly going where no science show has gone before.
0:05.0	The Naked Scientists
0:11.0	Hello and welcome to the Naked Scientists with me Katani and with Ben Vausler.
0:15.0	Hello.
0:17.0	This week we are scaling the heights to explore the science of mountains.
0:20.0	We'll be finding out what being at high altitude dust to the human body and how the processes
0:25.1	that make mountains could be leading to global climate change.
0:28.7	Plus we join the intrepid Laura Soul on an audio diary of her track up to Evers base camp.
0:34.3	And this is amazing stuff. She's a hero. She's giving us a first-hand account of how it feels
0:39.3	to be breathing the thin air at 5,000 meters and monitoring the physiological changes that happen as you climb.
0:46.0	Ben.
0:47.0	Thanks, Kat. We'll also hear about the desktop evolution experiment that saw sudden jumps in mutation rate and find out how looming
0:54.8	sounds like a car approaching or footsteps in a dark alley could enhance your eyesight
0:59.6	even before you realize that you can hear the sound. We'll be exploring how stresses
1:04.6	and strains can help shape the developing embryo and we'll hear how scientists have
1:08.6	discovered how we can taste fiz. Plus, Diana O' Carroll will join us us without question of the week. We'll be
1:14.5	finding out of spiders are brilliant architects or mathematical geniuses in order to build
1:19.4	the perfect web. So Arachna Fobes, beware. That's all to come on today's Naked Scientists.
1:24.4	If you want to get in touch with any questions or comments, we would love to hear from you.
1:28.0	Our email address is Chris at the Naked Scientist.com
