>> but, you know, the reality is, is that bees pollinate over 100 different fruits and vegetables. we're talking about strawberries, broccoli, apples, melons, pumpkins -- i mean, really basic fruits and vegetables that we eat every day. >> that's why what's happening in the bee world is causing alarm in the human world. bees are dying in droves and disappearing from hives. it's called "colony collapse disorder", or ccd. >> colony collapse disorder has affected over 10 million hives -- in fact, killed 10 million hives over the past six years. >> no one knows why this is happening. there are many theories. it could be a virus, or tiny insects called mites that attack the bees, or the problem may be man-made. >> we have pesticides that are put on everything, you know, from fruits and vegetables, beans, corn, soy, and bees fly around and they collect pollen and nectar from these plants, and, you know, those pesticides, you know, either kill them or significantly lower the immune system of the bees, so they get sick easier. >> while research continues, people are working to protect bees. liane newton helped start the national honeybee conservancy. >> our goals are to raise awareness about bees, educate, and make it possible for many people to get involved in this activity, which has so many interesting aspects to it. >> beekeeping isn't limited to farms and rural areas. many cities like manhattan are home to thriving hives, and teens like jaxon help tend them. of course, it takes a whole lot of protective gear. [ western-style showdown music ] when he was younger, jaxon was terrified of bees. perhaps that's why his dad suggested they give beekeeping a try. >> i thought he was insane because it freaked me out. but it started to fascinate me, and once i knew that you're completely protected, it's just, it's amazing to be around that many bees and having them flying around your head and know that you're protected. it's a really cool experience, and, just, it's fascinating. >> jaxon visits the hives on a regular basis, making sure the bees have the water they need. before opening the hive, he prepares a smoke pot. >> it doesn't harm the bees, but they don't like it, so they will disperse if they're in a large clump, which makes them much easier to deal with. >> jaxon carefully takes out the frames. he checks each one to make sure everything is okay. if there's a healthy queen and the bees are keeping busy, there's plenty of evidence. [ bees buzzing ] >> this, the orangey, maple-looking blobs in the honeycomb, that's pollen that they have brought into the hive, and the almost-watercolored substance around these bees here is honey that hasn't been capped yet, which they're still working on, and this is all capped honey, which they finished working on, and that's just storage for them. this is all capped brood, and it's bees being formed, and the bees will crawl out of there when they're ready to be born. >> when "teen kids news" continues, we'll tell you how you can help "bee-friend" the bees. we'll be right back. >> there has been a significant increase of unaccompanied minors crossing the u.s./mexico border undocumented. officials at the department of homeland security saying, "there has been a 92% increase of arrests of children under the age of 18 compared to the same time last year." most children coming to the u.s. to escape their dangerous home countries in central america. some military bases in the u.s. are turning into shelters to house the young migrants. a recent risk-behavior survey done by the centers for disease control shows that teen smoking has hit a new low. the survey conducted every two years since 1991 reveals that 15.7% of u.s. high-school students are smokers. that number is down from 18.1% two years ago. yet the cdc says other surveys show there is an uptick in the use of hooka and e-cigarettes among teens. president george h.w. bush celebrates his 90th birthday in style. the 41st president jumping out of a helicopter while strapped onto an army skydiver in kennebunkport, maine. bush also spent his 75th, 80th, and 85th birthdays skydiving. on his 90th birthday, he lands gracefully and is greeted by loved ones on the ground. the first time he jumped from a plane was during world war ii when his plane was shot down by the japanese in 1944. for "teen kids news," laura ingle, "fox news channel in the classroom." >> as we've reported, when it come to pollinating fruits and vegetables, bees are the "a"-team. without them, we'd have a lot fewer foods to eat. bees also give us honey, which many say can be a healthier alternative to processed sugar. >> we have to remember that it's still a sugar, so we don't want to go crazy with it. >> since honey is sweeter than sugar, you can use less of it. and if you think all honey tastes the same, you're in for a surprise. zeke explains that honey can be varietal. that means there's different varieties depending on where the bees gather the nectar. >> single-varietal honeys are honeys that come from a specific floral source, whether it be wild raspberries or wild blueberries, buckwheat, wild sage, orange blossoms. and honey from that floral source gives it a particular color, a particular texture, and a veryparticular flavor. so you have a honey from new york from an aster flower, and you'll see that it's very clear and amber-colored. and so this is buckwheat honey. it comes from washington state. and you'll find it has a much more grainy consistency as it crystallizes and more of a molasses... more of a molasses flavor. and then lastly, we have a colorado star thistle, and, again, this one you'll find is very buttery-smooth as it crystallizes, and even has kind of flavors of nutmeg and cardamom, and a very smooth, buttery texture. so those are three different varieties of what we call single-varietal honeys. >> so, whcan we do to help save the bees? >> there are numerous things that consumers and you and me can do about it. one is, buy organic produce, because the more organic produce that is produced, the less fungicides and the less pesticides are out there to harm our bees. >> another idea is to plant a bee-friendly garden. >> something that has a lot of flowers that bloom from spring until fall. obviously, don't use pesticides in your own garden, or fungicides. you can also, you know, buy local honey. buying local honey helps your local beekeepers. >> or maybe you might want to try your hand at becoming a beekeeper. >> it's a great hobby. you will be the coolest person on your block, and you'll be helping to save the honeybees, and you'll be learning something that will be of -- enrich your life forever. a great way to find out more is to go to thehoneybeeconservancy.org website, where you can see lots of information. for kids, we recommend that you visit our kids page. >> the message is pretty clear. if we don't take steps now to combat colony collapse disorder, one day, we may be without bees. >> three teenage girls have invented a generator that runs on a fuel that's as unusual as it is common -- urine! the machine breaks down urine into hydrogen, nitrogen, and water. the hydrogen gets turned into a gas which then powers the generator. one liter can give you up to six hours of electricity! >> if you have trouble getting up in the morning, blame biology. not the class, but your body-clock. i'll explain. >> when your alarm clock rings in the morning, do you find it hard to wake up? as isabel reports, you're not alone. >> i'm really, really tired... [ chuckles ] ...when the alarm rings. >> like, i want to turn it back off and go back to bed. >> i'm usually tired when i'm in school. >> i just want to go back to bed. >> i'm really tired in the morning. >> it's a familiar feeling, and it might not actually be your fault. >> and our adolescents are asked to literally wake up and go to school and be there at a time when their brain should physiologically be asleep. >> it has to do with the hormone melatonin. teens and adults don't have the same amounts of melatonin, so teens are chemically programmed to stay up later than adults and wake up later, as well. as a result, dr. meltzer says, teens are out of sync by as much as two hours with the adult world, and getting up early for school only makes things worse. >> that they need nine hours of sleep, and they're only getting, on average, about seven hours of sleep. by the end of a school week, they're 10 hours of sleep behind. i mean, it's more than a full night of sleep behind. [ alarm ringing ] >> and it's often hard for teens to catch up on the lost sleep. >> i would wake up in the morning and want to go right back to sleep every time. >> while many teecan function on a little sleep, caelin had an additional problem. even though he felt constantly exhausted, he still had trouble falling asleep at night. he finally got help at a sleep center. while we may not be able to change our biology, there are some sleep tips. for example, turn off the electronics well before turning in for the night. >> you can do without your cellphone for an hour. and go to bed on time consistently, like, anywhere within 10 minutes of a set time, and you should be good. >> researchers admit that life would be easier for teens if the school day started later. in fact, they found something interesting with kids who are home-schooled. since they don't have to wake up at a specific time each day, they tend to get more sleep than the rest of us, who get up early for school. >> ever take a close look at your state flag? you should, because you might be surprised at how much you can learn from it. here's brandon with this week's lesson. >> in 1629, the king of england gave lord calvert the right to form a colony in the new world. calvert called it terra maria. "terra" means "land", and maria was the name of the king's wife. "terra maria" means "mary's land." maryland. calvert designed a flag with two symbols -- his own coat of arms and the coat of arms of his mother's family, called the crosslands. the civil war divided maryland's residents over which side to support -- the north or the south. the coats of arms became symbols of that division. >> the calvert part of the flag, the yellow and black -- that was an image that was used to represent those marylanders who were siding with the north. the crosslands side, with the red and white, was used by those southerners who agreed with the rights of the confederate. >> throughout the war, the symbols were displayed separately. >> and it wasn't until after the civil war, when maryland soldiers were marching for the spanish-american war, that marylanders felt like there was unity again, like, they had healed the wounds of the civil war, and it was, in part, seeing the image of their flag with those colors all together again that helped to bring those people back together. >> the reunified flag was officially adopted by maryland in 1904. it's remained unchanged ever since. with "flag facts", i'm brandon. >> what does antarctica's ice cap have in common with james bond's favorite nightcap? i'll tell you in a moment. as the earth's most southern continent, antarctica is almost completely covered in ice that's a mile thick. scientists have learned that when there's a big earthquake elsewhere in the world, it can cause the antarctic ice to vibrate. i guess you can say that the south pole, like 007's famous martini, is shaken... [ as james bond ] not stirred. >> in "speak of the week," we'll find out that teens are pretty generous. >> want to guess which country has the most movie lovers? if you said the united states, you're wrong. actually we're ranked second place. people in india buy more than three timesthe number of movie tickets we do. that's not surprising. after all, india's population is almost four times larger than ours. but remember, we're the country that invented popcorn. >> this report is brought to you by yahoo digital crave. >> hey, everyone.crave. tech this out. the latest in games and gadgets and apps just in time for the summer. let's start off with the big guns -- the sony 4k tv. take a look at this gorgeous 55-inch ultra high definition tv with 4 times the quality of hd. it'll not only take your existing hd content and up-convert it to 4k, but there's also a lot more 4k content now, like from netflix and youtube and video unlimited. starts at $2,099 for this monster tv and goes up from there. you can get them all the way up to 85 inches. next up, i love this revolve product that takes your smart home devices and unifies it all. so instead of separate apps and remotes for your tivo and your nest thermostat and your sonos, this one device does it all. you download a free app for your smartphone or tablet, and, again, it's super-easy setup. it controls everything regardless of the company and product that you've invested in. love that?

calabrese: the medieval wall is thin, because they had no problem with harrows or stones. but in the renaissance time, the cannons, they became very strong, and they became a problem, so that's why it was so thick. steves: lucca's wall didn't come cheap. but all that hard work and investment combined with clever diplomacy earned the city a long period of independence. and to this day, the proud lucchesi have a strong sense of identity. rather than showcasing famous monuments, lucca's appeal is in its relaxed old-world ambience. stroll around. take time to let the city unfold. romanesque churches seem to be around every corner, as do inviting piazzas busy with children at play. the main pedestrian drag is via fillungo. strolling here, past elegant old storefronts, you'll get a glimpse of lucca's rich past, as well as its charming present. piazza amphitheater was built around an ancient roman arena. while the arena's long gone, its oval shape is a reminder of the city's classical heritage. locals have been gathering here for 2,000 years. today's attraction -- a flower market. piazza san michele also has ancient roots. it's hosted a market since roman times, when it was the forum. today it's dominated by the church of san michele. towering above its fancy romanesque facade, the archangel michael stands ready to flap his wings, which, thanks to a crude mechanical contraption, he actually did on special occasions. in its heyday, lucca packed over 100 towers within its walls. each tower was the home and private fortress of a wealthy merchant family. towers were single rooms stacked atop each other -- shop, living room, and then the kitchen. this one, lucca's tallest surviving tower, is famous for being capped with a bushy little forest. those making the climb are rewarded with commanding city views, all in the shade of its amazing trees. nearby, the church of san giovanni hosts nightly concerts celebrating the music of hometown composer giacomo puccini. woman: [ singing operatically ] steves: he was one of italy's greatest opera composers. puccini's delightful arias seem to capture the spirit of this wonderful corner of italy.
