i'm phil torres joined by lindsay moran, dr. shay somora and dr. dilworth. i just got back with an exciting week of my life, and it was all for science. with you jump on an one-ton tiger shark? well, that's the opportunity i got to do with these researchers based out of university of miami. we went on a boat in the bahama bahamas bahamas, in the name of sharks. let's take a look. >> shark on! >> shark. the very name inspires wonder and fear, vilified as the world's ultimate killing machine, but their bad-boy image is all wrong, according to these guys. >> i haven't had a single bad day with sharks in 35 years of doing business. >> if there is a shark around, you're likely to find jim in the water with the camera. >> we have 400 billion years of sharks shaping our ocean's health. and in the last 50 years on my watch we've literally destroyed it. >> one in six of all sharks that have been threatened with extinction . >> the university of miami, one of his primary missions is to study sharks in the wild so policymakers can make good policies based on science. >

i'm phil torres joined by davison.know the internet at all you've probably seen the face of commander chris hadfield. i got a chance to interview him. >> making space travel and this whole idea so cool again. it's fantastic. >> give us a with it into his world and a way for those of us that aren't living on the international space station to kind of have an understanding of what that experience is like and maybe imagine ourselves in space one day. >> and i had a chance to talk to him about all those amazing things. let's take a look. >> five four three two one and liftoff. tom and ivan and chris making their way to the international space station. >> international space station has long been a paragon of mystery, that is until one man brought it back down to earth. >> chocolate pudding cake, looks like it too. not bad. it is going to be hard to eat. going to be messy. >> chris hadfield the former commander of the international space station spent 166 days in space. but he didn't spend his time just doing experiments. i

. >> i'm phil torres. 'm an entomologist. sleep. >> it will track my sleeve. marita, costa and i see if the devices work. that's the team. let's do some science. [ ♪ music ♪ ] >>> hi, guys i'm phil torres, and welcome to "techknow". i'm with costa and marita davison. instead of science, let's talk football. now, i'm a broncos fan. when i saw what the 49ers did with their new stadium, i'll feel bad every time the broncos beat the niners. >> if their game is half as good trouble. >> when you think n.f.l., small does not come to mind. it's full of big excitement and business. don't think of it in terms of being a big player. the stadium may be poised to change that. i got to check out environmental advances. >> reporter: it's game day at levi stadium, home of the san francisco 49ers, at first glance the scene in the parking lot it classical football - tailgating team revalry. san francisco football is changing the playbook. >> we pushed architects and engineers to think about everything that could be green. >> reporter: in trying to win the green game. this is th

i'm phil torres, joined by shini somara, marita davison, and cara santa maria.e are in for a treat. shini - you just got back from on amazing journey to one of the most spectacular places in the world. please tell us about it. >> well, it was an absolute dream come true mission that i was on. i went to greenland and i was mapping glaziers with n.a.s.a. on a peace-free aircraft. the views were stunning. let's take a look. i travelled half a world away to get to a case some call the canary in the coal mine when it comes to climate change. greenland. i was here to observe an n.a.s.a. mission called operation icebridge. since 2009 n.a.s.a. has been flying airborne missions out of kangaloosa, a former u.s. airbase. the goal is to measure changes to the arctic sea ice and the ice sheet over greenland. we are just on our way to the air base and i am feeling kind of a bit nervous. i'm not the most relaxed of flyers. so let's see what happens. >> it was 6am, and about 10 degrees farenheit. >> so it's usually about a quarter of a mile walk to the plain. whatever condition

. >>> hey, guys, welcome to "techknow", i'm phil torres, joined by marita davison, and kosta grammatis. marita, you met a man who spent years as a crime scene investigators for human victims. now he and his lad is taking on the fourth largest industry in the world, it's a tragic. >> yes, we think of forensics dealing with human victims, we don't think of it as a bird. it's a wildlife services add, taking on the illegal trade in endangered species problem. >> some lines are extinct. how big is the industry. >> in terms of economic value, a $19 billion industry. techknow had an inside look at the c.s.i. forensic lab. >> reporter: the world's animal kingdom is under siege. since 1970 animal populations declined on average by half, according to estimates by the world wildlife fund. a big driver is wildlife trafficking. illegal trade in wildlife is a big global business, worth at least $19 billion a year. that makes it the fourth largest criminal industry in the world. right behind drugs, counterfeiting and human trafficking. it's been connected to organised qaeda. >> the rhinoceros, one of

there is life on other planets is to study life at the bottom of our ocean the today "techknow"'s phil torres was approximately 10,000 feet below the surface of the pacific ocean on board a sub marine called alvin. phil's voyage is part of a mission with the wood hole oceanic mission. i spoke to him on a one-way radio call. a bit like what you hear in the music. you hear the word over a lot. i asked what part of the ocean he is studying. over. >> hey, tony. we are currently 2,990 meter below the ocean. at the ocean floor. 100 meters off the coast of costa rica. it is amazing. we are next to a place. the pressures are literally crushing, so we are at the extreme depths where humans go, over. >> whoa. tell me more about what assist like done there, and what do you see. over. >> it is amazing, but it is cold. we are seeing some incredible landscape. a world i have never seen. there's octopus, amazing coral. it's incredible. over. >> my understanding is you are down there as part of a science mission. can you explain what it is all about? >> yes we are. it's bluf. there's a lot of -- beautiful. t
