i'm phil torres and i'm here with kosta and marita.ow, scientists are detecting millions of earthquakes around the world. what technology do you study to help mitigate them? >> here is san francisco's bay bridge. they absorb the areas of the earthquake while leaving the rest of the infrastructure intact. really, really cool. let's check it out. rising from the san francisco bay is the newest architectural jewel of northern california. the new bay bridge, which connects san francisco and oakland, is now open for business. and what a sight it is to see! roughly 280,000 vehicles travel the east and westbound lanes each day. it's now the widest bridge in direction. this is six years worth of round the clock time lapse video of the new 2.2 mile east span. the project cost $6.4 billion. this is earthquake country. the great san francisco quake of 1906 wiped out 80% of the city. the old bay bridge opened in 1936. and it sits in the worst possible spot: right between two major fault lines. the san andreas and the hayward faults. and the worst-

i'm phil torres and joined by dr shini somara, and dr crystal dilworth. crystal, you got your ph.d. , that caltech is a hot bed of scientific discoveries, happening every day. and today we are lucky enough to meet the scientists. >> absolutely, there's wonderful work. and we are caltech nerds. we have a reputation. we are featured a certain way on sit comes, "the big bang theory" tv show. >> exactly. i'll show you some of my favourite people doing incredible science. the m.e.r.s. is mcarthur -- first person is mcarthur prize winner, taking an approach to energy, global warming and conservation. >> climate change is not a far-off problem in the future. it's happening now, causing hardship now. climate change is real. we have to act now. >> the debate about whether climate change existed at all is falling to the background. i think people accept it's a reality. it's here. now it's a question of what do we do to combat it. >> on the front lines of combatting climate change is caltech aeronaughtic professor dr john deberiy. he's taking cues from animal. >> th

i'm phil torres, with me kyle sil, cara santa maria, and lindsay moran.indsay moran, the only c.i.a. operative - you are the in-house security specialist. you got me to look at a smart gun coming with controversy. >> that's right. we talk about the controversy later. first let's look at the technology. ironically after years of working for the c.i.a. in danger zones, i tried out gamutry worth -- gadgetry worthy of james bond in the sense of a high tech handgun. let's have a look. >> reporter: when i worked at the c.i.a. and had to sometimes carry a gun, i worried as a woman that i could be overpowered and have my gun taken and used against me. now, as a mum of two young boys, gun safety is a huge concern in my household. according to the latest statistics, each day approximately five children are killed or injured by guns. the newest smart gun, the ip1 is designed to alleviate both of these concerns by personalizing the weapons ability to fire. this works like a regular firearm, if we didn't tell civilians there's batteries, they wouldn't know. >> there's
