i'm phil torres and i'm here with he marita davidson and shini somara.t inside a tornado. >> i got in the vortek, to experience force 3 winds. to experience that was unreal. let's take a look. >> thank you very much. >> oh my goodness! coming down right now, major tornado. >> coming down another tornado. >> a deadly tornado rushes towards the u.s. chunt of oklahomcommunity ofoklahoma cit. ripped through the capitol on sunday. >> that was the tragedy in the ground but new innovations are developed in the lab to protect against disasters. >> we create tornado like vortexes. >> i'm at the national wind institute at texas tech university where they can actually recreate tornadoes. harold janes professor of engineering. designed this vortek. >> understand what happens to structures. >> tornado winds are rated on an es scale which aan indicator of the severity of the storm based on wind spreed an -- speed and debris impact. >> this is ef 3e, 150 miles or less. >> have you ever been in this? >> oh, absolutely. would you like to go? >> i'm going to build up the

shini somara and marita davidson.when i'm in the field doing my research, one of my big issues i'm working on is how to conserve our wildlife. i got to go down to the san diego zoo. sme they are prerving dozens of -- they are preserving dozens of different species. this zoo is frozen! so let's take a look. at the famous san diego zoo safari park, lies a zoo within a zoo, replaced by liquid nitrogen and cell cultures. this is san diego's frozen zoo. that's right, zoo. not the one you grew up visiting but one in which there are living cells from over a thousand expertise, preserved sd frozen, all to help protect future generations of animals currently facing extinction. what was the genesis for creating the frozen zoo? >> the possibility to save sells -- cells allowed us to undertake, each cell of an individual is capable of producing the entire individual. >> take me through the process of freezing cells. >> we get a biopsy, a small slice of that individual. fest >> we can take those cells and treat them so they can be

i'm phil torres and here with kosta and marita. story i got to do is one of my favorites. helping technology change people's lives. this is a robot that paraplegic people can use to walk again. let's take a look. >> hi! >> this dream happening today. >> these kids from a summer camp near aspen, colorado is if to give amanda a lifesaving gift. a gift she hasn't been able to do here since she was paralyzed in a horrific accident 21 years ago. >> now i want to invite the kids to have at it and rip into it. >> it is a buy ontic robot called exo. a battery powered external skeleton that gives her body the power to do this: >> are you ready? >> three two one blast off! >> whoa! >> and this. >> i'm walk, you guys! >> and even this! [ crying ] >> the technology is so cutting-edge that amanda is the first person in the united states to own one. >> the moment she stood up, i was just amazed because she's been sitting down for 21 years! and that first feeling to stand up again, it's just -- i would have been thrilled obe in that position. >>
