>> my role model was my dad, which is what i related to when it came to petra.ct me about her was her passion for her subject and her enthusiasm. i don't remember at the aim of 18 being that -- aim of 18 being that clear about what i wanted to do this science. it was inspiring. >> what i can relate to is not just the passion about the science, but the aryanism, she -- organism, she seemed to love the birds. that was me at that age. i can relate to being passionate about a creature and using it as a ol. >> i love the way she was fascinated by the animal. i was fascinated by the way she used robotic knowledge to enhance her research, it's a work. >> and an example of where science research is going. it's so cross-disciplinary, being an expert in one is not enough any more. it's great to see someone starting at stanford. he she has that handle. >> for viewers, young women waiting to get into science or mentors, what advice do you have? >> don't think because you are not at university, that you can't get in there and participate. ask your science teachers that you h

petra poroshenko the ukrainian leader calling on nato countries to provide them with technologically advanced weapons so they can prosecute their battle for effectively against the pro russian rebels. it's not clear at this stage what john kerry, the u.s. secretary of state, is going to offer. certainly there's going to be support for the ukrainian government. they're providing financial assistance and providing nonlethal military aid to the ukrainians at this point. thing like night vision goggles and flack jackets and other equipment like that. the big debate right now is should the united states and other countries start providing the governments in kiev with lethal aid, with weapons so they can carry out defensive actions and, indeed attacks against the pro-russian rebels in the east. one of the items being looked at are anti-tank missiles and weapon of that character. the big risk of course is that injecting weapon into that war zone could escalate the conflict. it's unpredictable to try and assess what the reaction of vladimir putin might be to the idea that the united states w

they want to go to petra and see what's going on over there. a warning, an advisory like this by the state department, that will clearly put a damper on that. >> wolf let me put it this way, a senior pentagon official an old friend of mine knows the middle east speaks arabic he says, i just won't go back there. it's too violent. you can't go to public places like malls. you can't go out to dinner. the place is just toxic. and that was a warning i have never heard in my career or ever. and he's watching the middle east. he sort of despairs with the situation, the spread of violence there, which the pentagon can't predict, nor can a country like jordan. so if a mall is attacked there, they are vulnerable, they are soft targets. there's only so much you can do to protect them. it wouldn't surprise me. >> stand by guys. we have more breaking news that's developing. the pentagon we're told may be rethinking a major anti-isis offensive in iraq. one factor in play the ability of the iraqi military to get its part of the plan accomplished.

mark: we had earnings from petra fact earlier this morning. joining us now.ning us on "town down." coming it -- "countdown." coming in, tell us what you are most concerned about in 2015? guest: obviously the oil price has an indirect business on our business because it determines the spending patterns of clients. fortunately with the position that we have in places like the middle east and north africa and with us relying largely on national oil companies we have seen these clients continue to spend through the down cycle. we're much less impacted than any of our peers. mark: you're implementing what you're doing with capital expenditure, and what could occur on those metrics if the oil price stays low or goes lower? guest: let me talk about this. we have taken measures to reduce the contract rates on two different occasions down by 20%. we have frozen salaries for staff. we looking to work with suppliers and vendors. in the north sea in particular, -- i think we all want fiscal relief from the government but my big concern is the stability of the industry an
