according to a recent study by a seismologist john but all of the university of southern california the earth's core is changing ok so see back in the 1970 s. during the cold war arms race the u.s.s.r. tested nuclear weapons in russia's. islands those tests 2 of m m particular were so powerful that they were powerful enough to travel over 4000 miles through the earth's core to seismology equipment and montana using that data scientists have been trying to calculate the speed at which the earth's core a moon sized iron globe swimming in a sea of molten lava spins it has sort of been assumed that it spins at the same rate as. but these new calculations show that the earth's core is in what they call it super rotation it runs a couple of a tenths of a degree faster each year meaning the corresponding under your feet right now will be nearly 5 miles away in one year in addition some scientists figure as that the speed differences in the earth's core could be attributed to variations of the inner core surface creating fiction now this new data doesn't mean the old data is wrong it's just that we're

the university of southern california crew recruits even though neither of them row. >>> a contra costa teacher is out of a job and some believe theer firing is personal. >> every day is earth day. >> that is science teacher doug scott speaking to reporters aross the street from the mount diablo school meeting. they were calling for his reinstatement at thea school. scott has been with the district 28 years. he says the principal joe alvarez fired him two weeks ago without giving a reason. >> 15 minutes to get what you want out of your room and on to your bike before we turn in your keys and beingpa escorted off campus. >> scott said last spring he flunked a student who principal alvarez later gave a passing grade to at the request of the student's parents. he believes that that feud -- that led to his firing. neither the principal nor the district would comment on the termination. >>> a lot to celebrate at the chasee center in san francisco. a bird's-eye view. the new home of the warriors. the dubs players and president are talking to the media and for the new ision hub. sharon katsuda is live at the chase center and they're calling this area thrive city for good reason. >
