airliners are being made of carbon fiber, not metal. and this is what lightning does to carbon fiber. bad enough on a normal camera. now look at it in super slow motion. you can see the fibers shredding what would be the skin of the plane. the solution, you can t see it, but woven into the carbon fibers is a layer of metal. it does add weight, but just look at the difference it makes. now you can really see the damage done by the lightning on this piece of carbon fiber. yes. there s an awful lot. you have torn fibers here. shredded fibers and it s an awful lot of damage. but this is without protectant. with lightning protection here you can see that the damage is much reduced. and you d be safe to fly on. you wouldn t really want to be flying on an airplane that did that. you wouldn t want to at all, no. reporter: one final test because we couldn t resist it.
the reason you run is because you are in a race. so you cannot walk. you cannot walk. you are going to ride up the whole west side of manhattan. you will be on the west side highway. so you will be looking over the hudson river. now, when you are up here, there is no push down on the pedal. all it is is a pull-up. if you don t feel like you have to pull-up on that pedal, sit down, add weight and get back up, balance on the pedals and give me a nice smooth pull up, up, up. small lever. there you go. the run is hard. it always is. it is the last part.
protesters has dwindled the past two years. in the wake of the controversial law, huge crowds are expected today. president obama will visit the gulf coast tomorrow morning and the president will get a firsthand update on the oil slick and will be briefed on efforts to contain the spill. graduation day at the university of michigan and the commencement speaker was president obama, who discussed the challenges of the economy in his address and it s derby day, despite a rainy forecast, churchill downs getting ready for today s kentucky. the horse to beat is sidney s candy owned by weight loss mogul jennie craig. and brian, early morning workouts there at the derby were postponed because of rain. so trainers had to work out horses inside the barn and hopefully the rain goes away before the race. brian: did i hear you correctly that jennie craig has a horse named sidney s candy. i know, i know. brian: doesn t seem right. it doesn t add weight to have a horse named candy. brian: i
centuries of european architecture because the buildings are still standing, because they weren t bombed to smithirines in world war i and world war ii. prague is one of the cities that defies the beligerent history of the 21st century in europe. as a backdrop, it s suitable, president obama thought a year ago to give a speech about ending the threat of nuclear holocaust, nuclear war, either between the united states and russia or between any nation and a any particular terrorist group and nation that inspires to achieve or develop nuclear weapons so the idea was come back here, sign this treaty and increase what the president thought was lacking in the u.s. approach to a denuclearized world which was credibility. he thought to deal with iran, to get more sanctions between the united nations security council, to bring russia and china on board, the united states had to do more visibly to denuclearize or to reduce its nuclear stockpiles and then with that credibility, add weight to its
and the development of the disease. with me now is hannah churchill from the alzheimers society. is this intriguing new evidence of something that we thought beforehand might be connected or has this come out of the blue? that research around cholesterol today has been fairly mixed. this adds weight to the argument that this might be a contributing factor to our risk of dementia. it is a large study looking at nearly1 million people. and following up on a certificate amount of time, does add weight to that argument. the difficulty with these things is linking cause and effect, proving that one thing, it may make you statistically more likely to get something, but it does not prove that one is going to lead to the other. that is exactly it. that is always theissue that is exactly it. that is always the issue with this type of research. their next step to establish that link is to use this as a springboard into other
