the current theory of physics suggests that the expansion of the universe slow down after the big bang and would then contract. instead with seems to be happening is that galaxies seem to be flying apart faster than ever before. scientists believe that this force is called a dark energy and it accounts for two-thirds of the universe. >> this acceleration defies the current theories of feet -- theories of physics. scientists want to know where the energy driving the universe apart is coming from. they are using the hubble space telescope to fault -- to find out. they will measure how fast galaxies are accelerating away from us. one of the researchers involved told me the results may show that the universe may continue to accelerate apart forever. >> the bigger it gets, the faster it will go. that will be a universe that just expands forever. the piece of the universe that we get to see will have fewer and fewer galaxies in it, it will be a dark, lonely, cold place 100 million years from now. >> the solution will rewrite theories of modern physics and change our own notion of the univers

but the physical laws of sound are universal. at the root of all sound is vibration. [bell tolling] not only the root of all music is vibration, but in some sense, perhaps, the root of everything is vibration. everything is moving all the time. the earth is moving. the sun is moving. on the earth, the waves are beating against the shore. everything which is, is vibration. in order to have a sound, you need a physical object which vibrates, whether it's a cello or a speaker in a radio, you need a medium to carry that vibration. typically, it's air, and finally we need an ear, an ear drum, and a brain to turn it into something that's meaningful to a human being. [flute plays] the simplest sort of sound is called a sine wave, and i can display that sound on an oscilloscope. of course in nature, nothing is so simple as that. there isn't just one sine wave happening at one moment. actually, there are many sine waves all adding and subtracting. when you listen to a sound, when you listen to a musical note, you hear several things.

university of virginia retooled his modern history course for this semester's online debut. the class usually open to 120 students saw enrollment soar. >> 42,000 students around the world. >> reporter: to put it in perspective, in order to reach the same number of students, professor zellico would have to teach his course here at the university of virginia for 350 years. since 2011, some 2.5 million students from hundreds of countries have signed on, even though m.o.o.k.s are not offered for credit and completion rates are low. some educators say the potential exists to revolutionize higher learning. 38-year-old dawn smith was looking to change careers. >> i wanted to go into health care communications. but i needed some textbook knowledge. and i felt that in order to be taken seriously as a candidate, i needed to show that i was doing something proactive. >> reporter: there are concerns, however, about measuring student progress. the lack of student-professor interaction, even the sustainability of m.o.o.k.s. >> imagine taking a university and removing all of the really fun

university of maryland professor jim gates will be awarded the national medal of science in a ceremony at the white house today. gates specializes in string theory. gates was also named a regents professor making him the sixth person to receive that honor since established. >>> millions of bottles of cough syrup are being recalled because of a possible poisoning risk to children. the caps on triaminic and theraflu products can fail allowing kids to open them. there have been several incidents of children swallowing large amounts of the medicine. one required medical attention. if you have one of these products stop using them and contact the maker for a refind. >>> right here on "news4 midday," the super bowl commercials people >> announcer: you're watching "news4 midday." >>> marylanders could soon get relief in they fall in sick. maryland lawmakers are considering a bill that would guarantee workers seven paid sick days a year. the baltimore sun would earn employees one hour of six leave. >>> the dow climbed above 14,000 today for the first time since the great depression. looks like

scientists believe that we are entering a new era of physics and dark matter is the best frontier. -- next frontier. >> let's try to throw some more light on this for you. we saw the report there from the route -- from the doctor, and he joins me live, along with a princeton university student. big mission impossible today, so far, to find dark matter. do you think you will be successful this time? >> this has the most advanced technology, the best laboratory in the world for searching for dark matter. we expect exciting results, possibly. we expect to see it in stockholm at some time, maybe. anyway, if we will not get some great and exciting results, we will make any way an important step in the progress of knowledge. >> your reference means that if you get this right, you are bound to go to sweden to collect the nobel prize. as a ph.d. student in -- at princeton, this must be a dream come true to be involved in something like this. >> it is definitely a great experience. it is amazing to be a part of this experiment. on a daily basis, even within the individual projects, you are alw

. >> onemichio kaku is a physics professor at the university of new york. welcome. >> glad to be on. >> how big a deal are the leaks and how do you define the problem? >> it is scandalous. we are 68 years into the atomic age. we're leaking nuclear waste daytiming all the way back to the nagasaki bomb. outside of russia that makes for the most contaminated nuclear site on the planet. >> wow. >> at the time of sequester, taxpayers spend $2 billion per year just maintaining the cleanup operation. then it was revealed that hundreds of gallons of high-level toxic waste have been leaking over the last several years right into the ground. eventually into the ground water and maybe the columbia river. >> you say the most contaminated site in the world behind places in russia. who's at risk? >> we have to realize that nuclear waste is a toxic witch's brew of chemicals, the most dangerous known to science. plutonium, enriched uranium, nitric acid solvents all mixed in a liquid vat. and we have 56 million gallons worth of this toxic stuff. to get this into perspective

the universities and the talent because what we have done here, is not only the physical infrastructure, not only creating conditions for businesses to be successful, but we found that we should invest in the very talent that is here and expand on that talent and so it is the noble laurets and the post doctorate students that are here and they are working with people across all of other disciplines, start ups, technology, you hear these great stories and i have seen them myself and we walk in and people no longer using these small microscopes, but they are looking at 3 d technology from auto def and we are looking at cells in three different ways, four different ways, expanding, deepening, all of the science, this is the movement that we have, and this is our new economy and this is the collaboration that is going on and we have a lot to celebrate in our city, whether it is the giants hopefully the 9ers. i would say that it is the people but we keep having cake for very good reasons we, have the talent that is here and ucsan francisco is a great core to attract this and we are inviting

i actually dabbled in it years before as an athlete at the university of virginia. the first time it really stuck as something more than a physical practice was during my second deployment when i realized it was as simple as getting on the mat and breathing meant i was still alive and i could cope with different traumas that time. >> with that said let's do a couple of poses. let's get into the first pose. >> she was telling me as we prepared for the segment this is how she starts every time she practices. >> this is what you would do in iraq? >> yep. >> am i disturbing you? was that the concentration part? >> that's okay. just basically getting physically grounded helps you mentally and emotionally calm down, get centered. starting with a very simple breath-linking movement. inhaling, sit tall and exhale to twist. >> i know you can't speak for all the troops. what were some of the specific thoughts that went through your mind as a person who saw the casualties of war in iraq as you sat down to do your. >> if we can find things to simplify and get out of our heads w
