More americans report getting less sleep. now a study in the journal "sleep" may have found a connection. researchers put 225 people in a laboratory setting. some of them were allowed to sleep ten hours a day. while the others were allowed only four hours sleep. after 18 days, the sleep-deprived group gained about 2 pounds more than the group that slept well. the weight gain came because the the sleep-deprived ate 500 extra calories a day during the extra time they stayed awake at night. in othe...

Cancer research center. were also working with a doctor who is the lead on this from the chemical census institute and dr. charley johns son from penn physics. all of us together are working to see if we can figure out the best way to identify a scent, an odor that can help us, predict who already has cancer, even before this sort of standard screening test would be useful. jon: we have some video now of dogs and women obviously in a training session. but as i understand it, you wouldnt actually...

Additional training that can take place where they can become assessors, trained assessors or even experts at some point and that all depends on how good their god given talents are. >> in a nontraining environment once the folks who have been through your training are out in the field, how do they actually test the seafood? are they smelling, tasting, both? how much of a sample are they smelling or tasting at a time? >> well, one of the things they learn in the class is that the environment has...

Yeah, if you look at the video, i dont know if you can run it for -- on the show. >> jeff: its rung. >> okay. the first six seconds of the video, there is a lot of white material coming out of the end of the pipe. and that is the gas. in fact, you can see it float upwards in the video. quite a bit more rapidly than the oil does. >> jeff: and then it turns dark. >> right. and thats the oil. toward the end of the video. i based my analysis -- yeah, go ahead. >> well, i mean, as another engineer, y...

Video, there is a lot of white material coming out of the end of the pipe. and that is the gas. in fact, you can see it float upwards in the video. quite a bit more rapidly than the oil does. >> jeff: and then it turns dark. >> right. and thats the oil. toward the end of the video. i based my analysis -- yeah, go ahead. >> well, i mean, as another engineer, you trace a particle, then, and you have software that measures how fast its going? >> exactly. the name of the technique is called particle...

Explain, answer the first question. the second question, i guess i would have to leave to others. so to briefly walk you through where this calculation comes from, its -- based on a measurement technique of fluid measurement technique, particle image velocity symmetry. scientific word for measuring flows using, look at how fast particles move. >> you basically look at this for two hours, i understood. measured the speed at which and rapidity at which particles were moving through this video. bec...

>> well, i can, i can certainly explain, answer the first question. the second question, i guess i would have to leave to others. so to briefly walk you through where this calculation comes from, its -- based on a measurement technique of fluid measurement technique, particle image velocity symmetry. which is just a scientific word for measuring flows using, look at how fast particles move. >> you basically look at this for two hours, i understood. measured the speed at which and rapidity at whi...

And initial prototype was built in collaboration with partners in several european countries along with israel and chile. for now tobias beringer and his colleagues are practicing with it in a laboratory setting the. robot as its grip are on in front and its vision system above it recognizes the peppers where they meant to be located in the vision system plans the way the robot is supposed to approach the pettus and then pick them up and attitude on. but can the robot actually compete with human...

Has occurred at the same time more americans report getting less sleep. now a study in the journal "sleep" may have found a connection. researchers put 225 people in a laboratory setting. some of them were allowed to sleep ten hours a day. while the others were allowed only four hours sleep. after 18 days, the sleep-deprived group gained about 2 pound more than the group that slept well. the weight gain came because the the sleep deprived ate 500 extra calories a day during the extra time they s...

Margin of error? >> thats right. when this technique is done correctly, in a laboratory setting, the window of error is very small. say, plus, minus 1%. really hard, good engineering number. and because of the -- because of the various variables here, im not able to get, im not confident beyond plus or minus 20%. >> so the estimate of 5,000 gallons. a day you, have no doubt that is way, way low. >> right. >> you are saying it could be as high as 70,000? >> well, i calculate from the video, which...
