Personnel. and one of the big things they can do is target specific individuals using frequencies that are not necessarily discernible to the human ear, but can actually have huge physical effects on the human body. >> so steve, you have to admit it. it sounds like a mystery straight out of the cold war. do we have any idea who did this? >> oh, yeah. this is a bit of a blast from the past but not that far off the beaten path in terms of intelligence collections operations. i think we might be ge...

>> well, wup of the key possibilities here, don, is that its just like the correspondent in havana mentioned. it could be right out of a spy novel and what were talking about here is the intelligence services of cuba or russia. and the reason the russians would be involved in this is because they have researched acoustic weapons for many years and theyve been looking at how they could possibly use them, not only to gain information but also to conduct attacks on personnel and one of the big thin...

Cell and transform it into other types of cells. >> parts of the heart would then be bio-printed, piece by piece. and soon you would have a new heart. how long would it take to print a heart? >> the printing of the heart, i believe, could be accomplished in essentially a single day. >> dr. williams and his team arent the only bio-printers on the block. a group at cornell university has bio-printed a human ear. >> cold collagen gel being deposited onto the warm plate. that enables you to get real...

Low frequency vibration. theres a pulse going on, and this pulse, you couldnt hear with the human ear. you would feel it perhaps but you wouldnt be able to hear it with the human ear. theyd sped it up so you can interpret it by the human ear. so thats not really what it sounds like. remember, the lower frequencies in the ocean travel much, much further than higher frequencies. thats what youll here, that low frequency pulse. it wont give you much characteristics to tell you specifically what it ...

Indicates its the close e to the pinger, but obviously that wasnt the case. while im saddened that the families will have to wait longer im anxiously awaiting the results of the next area where theyll search to the north. thats why we had the two-hour length ping receptions so that to me in my mind would be a really good place to look and i think thats going to present some challenges as rob could probably tell us about, but its a little bit deeper than before. >> what are some of the challenges...

Its a frequency designed to be heard not by the human ear, but by acoustic listeners. those acoustic listeners will then provide both a visual reference point, a wave form, and an audio sound which can be heard then by the ear. the pinger is not only designed for the 37.5, but the rhythmic one-second pings. theres many noises in the ocean. some of them are mammal made. others could be from other machinery. the sound -- we learned last night and over the last few days sound travels far, especiall...

>> no questions? >> no. >> everyone agree? >> my question to paul would be what is the receiver -- theyre getting this on receiver. so you wouldnt actually hear this -- would this be something to the human ear? >> thats interesting. you said you can hear it, but it also has a visible -- >> well, you can hear my example. my example was one thousand cycles, well within hearing range. but in actuality, were looking for something that is about double the humans highest limit of hearing when youre a ...

Theres one of these on the cockpit voice recorder and data recorder. two boxes, thats the battery. this battery does not keep the memory in it, the memorys already stored, its solid. even after this goes off, the data is still stored in here. ive had that question. >> this battery is for the actual pinging sound? >> thats correct. and we have a thing of water here. how does it work? >> ill place it in there in a second. >> whats going to happen, we have 37 kilo hertz. which is higher that the hu...

And director of special projects is with us. former transportation general mary schiavo, and analyst and veteran pilot miles obrien. david, you have the pinger, explain how it works. >> this is the pinger, it gets replaced on the c check. theres one of these on the cockpit voice recorder and data recorder. two boxes, thats the battery. this battery does not keep the memory in it, the memorys already stored, its solid. even after this goes off, the data is still stored in here. ive had that quest...

Have expect it to be when you consider that and how deep the water is and the competing noises in the ocean when the waves are smacking around it illustrates how difficult this job is. you have to be in a two-mile radius to pick this up. you dont usually hear with the the human ear. they have special equipment that is designed to detect that snapping sound. >> and searchers have, you know, they said that there are pieces that are floating. the pieces that are floating today may not be floating t...
