think that that is what is in the mind of members of the security council, that is in our mind. >> the facts speak for themselves. for dates israel has maintained the status quo and will keep on doing so. let me be crystal clear. israel will not agree to any international presence on the temple mount. such a presence will be a change in the status quo. >> now there are many calls from security council members to end the violence and end provocative acts. but right now there seems to be little appetite for implementing the kind of monitoring force that the palestinians have been talking about. >> reporter: that was kristin saloomey at the united nations. nuclear armed north korea has threatened the u.s. and south korea many times so it was no surprise the inflation was number one on the agenda when president obama complete with south korea's president today,

national security correspondent jamie mcintire has more. >> antonio, north korea has done a lt of saber rattling lately, threatening both south korea and the you united states with its nuclear arsenal. president obama indicated he is willing to negotiate but only if north korea is serious about giving up its weapons. >> the meeting comes as north korea has been issuing increasingly aggressive statements and amid signs pyongyang may be planning a space launch or nuclear test explosion in defiance of u.n. security council resolutions. the two presidents jointly expressed deep concern about the north'north's intentions. >> today president park and i are reare ar re reaffirming.

agreed to the deployment but president obama insists there's no contradiction between republic of korea having good relations with both u.s. and china. >> i don't see any cracks in the relationship at all. i would argue that the u.s. rok relationship is stronger than it's ever been. >> the u.s. is almost 30,000 troops stationed in south korea and is bound by treaty to defend the south if it is ever attacked by the north because the korean war is not officially over, ending as it did in 1953 with an armistice not a peace treaty. president obama says his records on iran and cuba says he is willing to engage in countries that have in his words a troubled history with the united states. but so far there isn't a shred of evidence that north korean leader kim jong-un has any interest in staying up the president's offer.

state's busiest highways. one woman was forced to tread through mud after abandoning her cars. these images were posted on social media, as they called 911 and waited for help to arrive. friday, rescue workers spent hours helping injured and stranded motorists to safety. the road closures meant hundreds of big trucks were still stranded in traffic over a ten-mile stretch. and californians are being told to expect more heavy rain flash floods and mudslides. despite the danger, scientists say there may be and unexpected benefit to the thunderstorms, they could reduce the drought but the state would need four

years of consecutive heavy rain to alleviate the drought. and digging out seems like too much to take. the u.s. government said today it's canceling two potential off shore leases for oil in the arctic. shell said it would not explore for oil in the area after disappointing tests. a reason to cancel leases for the next two years. companies for other countries still want to drill in the arctic but there are concerns they do not have the ability to handle potential oil spills. beaten and tased and left for dead. the decision and the back story. and why apple may have to fork over hundreds of millions of dollars to a university that took the company to court.

>> a jury in wisconsin today ordered apple to pay $234 million in a patent case. the jurors had earlier found that apple infringed on chip technology at the university of wisconsin, prolonging battery life. apple says it will appeal. a new study is channeling old ideas that humans need eight hours of sleep daily. the study followed members of three tribes of modern day hunter gatherers i gatherers inh america. researchers found that the tribes are healthier than americans despite sleeping a little less than six and a half hours a night on average.

they also found their sleep patterns were more closely tied to changes in temperature than changes in light. joining us with more on this is dr. jerry segal, he led the research team that conducted the study. he joins us via skype from los angeles. thank you for joining us. your main study is that you don't believe in the conventional wisdom that people in the modern world with all our lights and tvs ended up sleeping less than our ancestors did. >> what we found is on average these hunter gatherers slept a little less than we do. however you should not use that 6.4 number that's the amount of actual sleep vs. the period of sleep which is more what we experience. probably don't want to get into the details. but if you apply the same measures to populations in the united states, europe or japan, and to these subjects, they

sleep a little bit less, not a huge amount, but a little bit less, but what's clear is that they don't sleep more. which has been claimed that that's been repeatedly made. >> all three tribes had very similar sleep habits? >> yes, very similar. >> and the theory was the days before electricity people would go to bed soon after sundown and sleep until sunrise and this study debunks that? >> yes, we saw on average these groups went to sleep at 3.3 hours after sunset long after it wos pitch dark. and i can say of the 94 people we examined, not a single one was going to sleep at sunset. that was not at all typical pop. >> and they were waking up before sunrise. >> in general they were waking up before sunrise. what we found is that the awakening time was closely tied to temperature. they would wake up at the

minimum temperature of the night. and that was usually near sunrise. but in some cases, the minimum fell after sunrise. and that was still when the participants woke up. they woke up at the low point of temperature. >> so in light of what you found, what is sleep deprivation? does it vary by individual? i'm one of those people who if i don't get eight hours of sleep for a few days my eyelids start twitching. >> yeah, i think there are several ways to look at this data. one is that perhaps, the sleep time of these groups is somehow more efficient. certainly, there is individual variation in how much sleep you need. and i certainly don't advocate anyone reducing their sleep time or thinking it's okay to reduce their sleep time if they're sleepy or if they're you know having any of the symptoms that they can attribute to sleep

loss. serge there are people in our society that sleep deprive themselves and they suffer the consequences of that like -- >> so is it possible to say it's still better to sleep more than less or not necessarily? >> that is a bit of a misconception. there have been several large ep deem lock caepidemiological stun seven sometimes eight, seven more commonly, and people who sleep more or less than this have shorter life spans. but somewhat surprisingly, people who sleep more than this, have a greater shortening of life span than people who sleep less. and this is something that is completely understood. it's not understood for example whether reducing their sleep would be beneficial, but what we do know is that more sleep isn't better. it's not a linear relationship. >> that's a fascinating study and gives some hope to those of

us who work these off-hour shifts who are usually obsessed with sleep. dr. jerry segal from ucla. thank you for joining us. >> thank you. >> the ancient city of pompeii, a thousand bodies were found covered with hardened ash during excavation of the ancient cities. last month a team of scientists began using cat scans to study the citizens. >> we discovered the absence eveof cavities in the teeth. the mediterranean diet as been found affecting these.
