. >> it's a bionic robot called and exo. a battery powered robot giving her legs the power to do this. >> are you ready? >> two, one, blast off. [ cheering ] >> and this. >> i'm walking, you guys. >> and even this. >> the technology is so cutting edge that amanned say is the first person in the -- amanda is the first person in the united states to own one. >> the moment she stood up, i was amazed. she's been sitting down for 21 years. the first feeling to stand up. i would have been thrilled to be in that position. >> it was an emotional moment for the kids who spent the past year selling countless cups of lemonade and raising money from happen. >> it was my dream right there. all i wanted to see was her walk. it was amazing. >> amanda - it was the cull mipation of a dream -- culmination of a dream she had ever since she was told she would never walk again. >> the profound moment was when i stood up and tried to see the children's faces and some of them, the little ones - they were just in awe. and to have that heart to hear

so. >> this is exo's headquarters where the magic is made and perfected.people who are paralyzed a chance to do what they have been told was impossible. >> i feel like the luckiest man alive. >> nathan is one of the robot's inventers. not build for the are meat feed but for the credit military field. >> there's a huge problem in the field for soldiers carrying the large loads, in fact they want to carry more. we were helping to develop exoskeletons. to carry the person's weight and more as well. >> it can be powered by a small battery pack and then there's that whole walking thing. >> it takes over the function of the muscles in your legs. it can do that either completely, for a person who's completely paralyzed, or partially for someone who is rethroarng walk, like someone who -- credit relearning to walk, like someone who has just had a stroke. >> i put the device in walk-mode and take the first right step and as i move my body the exo will move with me. if i don't move to the any next position the exo stops. >> test pilots like amanda boxtel and jason g

. >> we see them as exo planets. what if we are an exo planet. they are having this discussion right now on blue eye. awe who is an exo planet. >> outside of ourselves. so it is their world. and we're just, rotating around it in another galaxy. they're thinking abut eout eati us. >> they probably have belttter taste. >> we don't want it. andy, an interesting fact. perhaps they're aware of who we are. but they have no interest in coming near us. did they get our little, what do we send out messages? >> of the radio waves. >> they're getting but not answering. >> they're not taking our calls. >> we'll get back to you. >> exactly. >> i find all of this to be sad. i know i won't live long enough few of get to the planet where i will be away from other people. makes me sad. i'm sequestick of. they say, it may have liquid water necessary for life. how do they know. in all of universe, can't there be life that doesn't need water. have they not seen signs. in signs, water killed the aliens. >> that other move ve. country music killed them. >> an exceptio

. >> we see them as exo planets, but what if to them we are an exo planet and they are having this discussion on blue eye. it is a planet outside of ours. it is their world and we are rotating around another galaxy. they are thinking of eating us. >> they probably have better taste than we do. they probably look at us and say we don't want it. andy, that could be interesting. they are aware of who we are, but they have no interest in coming near us. do they get our messages? they are getting them, but they are not answering. we are like jehovah's witnesses. >> they are not taking our calls . >> we will get back to you. >> i find this sad because i know i will not livelong enough to get to one of these planets to get away from people. that makes me sad. th is something i am sick of. scientists say, well these planets may have liquid water which is necessary for life. how do they know? in the vast universe is there life where maybe they don't need water? in the movie water killed aliens. >> and remember the movie where country music killed them? >> that's my point, we just don't know. >> what a

and that's why i call it an exo sen shall threat. if 50% of mothers across the country realise what those impacts do, and tell their kids "you can play any sport except tackle football", it won't kill football, it changes the socioeconomics so the people who play football will be like the people who box. the irony is at the absolute apex of power with the country n.f.l. crazy about 2:1, top rated shows, we have this lurking threat. we need dramatically to move on helmets. the counter helmets products against skull fracture. >> sports is a dog eat dog world. bit on a lot of back stabbing. the bigger you become the bigger target you have: what happened to leigh steinberg, how did it go from a peak to pretty much crumb bling? >> in the year 2000 a huge merger mania hit the sport industry. the concept was to buy up and bundle practices in football, baseball, boxing, and then you use them to trigger a marketing arm that could market teams, leagues, any interesting individual corporations. and then build a studio not in the brick and more

it was-- so not only has science vince then we discovered a thousand exo planets, the his boson, we have the-- we have strong ideas that a multibirth exists. i mean the list goes on and on. >> stephen: multibirth. >> a multibirth. well, it may not be just one universe. there may be many universes. but there wasn't -- >> doesn't science depend on experimentation. how are you going to -- >> bring in the other neil degrasse tyson -- >> it is a theoretical theory at this point but an intriguing one with compelling argues for why it would be so. >> you get people excited about time. >> we also discovered dark energy. this has been a serious pressure in the vacuum of space pushing against the wishes of the collective gravity of all the galaxies making expanding universe accelerate. all in the last 34 years. >> here is what i don't like. i saw you on the cnn talking about how important science is. >> yeah. >> and that science says that we shouldn't have both sides of every debate. you know. like we can't have people who say the berth is round and bring on flat earthers too. don't you want it to

star light making it easier to see planets the star light makes it difficult to detect the so called exo planets. nasa hopes photos will provide clues to whether the distant world could support life. >> i remember seeing one of those things in a james bond movie. >> yes. >> the evil guy used it as a weapon. just saying. >> if you can't make the astronomical rents in san francisco, at least you can make fun of them. >> this is his take on a $5,000 a month water front condo in the up ask coming mid market area. luxurious living on its finest. >> how about the $2100 inland unit with open floor plan. 1.25 square feet. daily house keeping included >> if that doesn't suit you here is a basement apartment for $3500 a month. >> yes. yes. >> aroma may be an issue there. and a $4100 cozy studio with sky lights you get the idea. >> it's good. >> let's check on the forecast now. >> our penthouse suite on the roof of the kgo broadcast station. how about this photo sent to us yesterday yesterday's sunset. what a beautiful sky around the bay area. from this point of view. sunny skies around the bay als

this technology so veterans of iraq and afghanistan can control mechanical arms and legs to create an exo-skeletone mind. this is something out of "ironman" comics. the obama administration wants to help people with alzheimer's being able to record a memory and have a brain pacemaker so people with alzheimer's can push a button and have the memory put in their minds they have forgotten. this is going to revolutionize the way we view mental illness, alzheimer's and the way we can conduct our business if we can record and upload memories. >> there is a new form of entertainment, you can record smell, taste and touch as well as a full range of emotions which can be reexperienced by the audience. this is amazing. >> that's right. one day we may have a brain net where children an facebook send emotions and memories across the internet. it would be the rage of face book. eventually the movies might be replaced. instead of looking at a two-dimensional screen we might send emotions and feelings to create total immersion entertainment. this could have enormous implications for swrnds standing of the mind,
