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 the u.s. with five lanes in each 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 t

i am phil torres, marita, what you got?d a chemist, an unlikely pairing and their innovating in the kitchen using convention the laboratory instruments. use being liquid nitrogen and disk techniques create new, interesting and in some ways more nutritious food than what we were used to. so let's check it out. for generations, julia child taught modern kitchen techniques to millions. here she is on her pbs show demonstrating how to make beef stew. >> if you want the flavor of the be i don't knows and the beef to all presen blend themselves wite stew. >> that was then. >> oh, i can't believe how good that tastes. >> but this is now. ♪ ♪ >> ♪ ♪ >> chef joshua is on the cutting edge of modernist cuisine at the bizarre restaurant in los angeles. and is one of many chefs experimenting with new ways to cook. >> so now here we have what is called a liquid all. >> i have never heard of it. it's such a different and unique look the way it's presented. >> liquid olives, how about stake cooked in a bath or juice made in a centrifuge. l

i'm here with marita and rachelle. hi, nasa seekers mission, this is a gc-8, loaded with millions of dollars of equipment measuring the air as we're flying through the gulf. it was a pretty incredible experience. let's take a look. ists 7:30 in the morning and -- it's 7:30 in the morning. and hangar 9 is buzzing with excitement. >> any last questions about what we're going to be doing today? save jet. >> from a distance our plane looks like any other. but close up you can see it's anything but. i'm minutes away from boarding this plain with nasa experimentalists. it is a nasa gc-8, trying to measure the pollution and the atmosphere. it's a three pronged attack. the signs of the tc 8, after the u 2 spy plane. the er 2 application is a sight to see. everything about it has the feeling of a flight to space. the men who fly the plane undergo special training and wear a pressurized flight soot. several weather probes collect the information and beam it back to earth. >> seated, door closed. >> the men and women are learning

as marita davidson found out, not just in california but perhaps around the world. >> rising from the depths of the san francisco bay is the newest architectural crown 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 widest bridge in the u.s., with five lanes in each direction. this is six years' worth of time lapse video of the new 2.2 mile east span. the project cost $6.6 billion. the bay bridge is a stunning engineering feat for another region. something that's not visible at first glance. crumple zone technology. until now, crumple zones have mostly been used in car. they absorb the energy by controlled deformations. so engineers say this new bridge won't collapse, even in a powerful quake. this is an animation of how the bridge responds to a major quake. the engineering community considers the animation game changers. first one is sheer link beams. inside the 525-foot tower on the self-anchored suspensi

. >> well, joining me live from seattle, washington, is "techknow" contributor marita davis.ood to see you. good to have you back on the program again. >> thanks, tony. good to see you, too. >> i got to start, once a grove is infected, what is that, sit crews greening. once the grove is infected, how do you return a grove, a tree back to health? >> so tony there, is no known cure. right now there is no known cure for the citrus greening deed. there are only mitigating strategies. there is no cure at all. it's a big deal. it's starting to decimate those citrus groves in florida. >> tell bus this super high tech approach of killing the bad bugs, but is it toxic to other insects and why isn't it being done more? used more? >> reporter: yeah, so agriculture researchers have had to a triage to start to understand and come up with solutions to combat the disease. one of them is a high tech thing that you referred to. it's called rna, a natural process involved in all of our living cells to combat viruses. but what it can do is violence gene expression. and so what researchers have
