NATISHA LANCE, CNN STUDENT NEWS: Fridays are always awesome here on CNN Student News. And we thank you for spending part of your Friday with us. Hi, everyone. I'm Natisha Lance, sitting in today for Carl Azuz.
LANCE: First up, we're talking about hearings on Capitol Hill that caused controversy even before they started. The House Homeland Security Committee is holding these hearings to look into the radicalization of American Muslims. Basically, the idea that a group like al Qaeda could recruit U.S. Muslims and turn them into terrorists. Some critics called the hearings an unfair attack on loyal Americans. But Representative Peter King, who's the chairman of the committee, says that the goal is not to condemn Islam as a religion or American Muslims as a group. But he says the hearings are designed to limit the threat of terrorism. And he also believes they're important to America's safety.
REP. PETER KING, (R) NEW YORK: Let me make it clear today, that I remain convinced that these hearings must go forward and they will. To back down would be a craven surrender to political correctness and an abdication of what I believe to be the main responsibility of this committee: to protect America from a terrorist attack.
LANCE: One of the people who testified during yesterday's hearings was Representative Keith Ellison, the first Muslim elected to the U.S. Congress. He acknowledged that some Muslims are responsible for violent actions. But he said you can't blame an entire community for the evil of some individuals. He got especially emotional talking about a Muslim paramedic and police cadet who died trying to help others during the 9/11 terrorist attacks.
REP. KEITH ELLISON, (D) MINNESOTA: Mohammed Salman Hamdani was a fellow American who gave his life for other Americans. His life should not be identified as just as a member of an ethnic group or just a member of a religion, but as an American who gave everything for his fellow Americans.
LANCE: Bullying has been a big topic in the news recently. And yesterday, President Obama and first lady Michelle Obama hosted the first ever White House Conference on Bullying Prevention. Parents and students got together to talk about the effects of bullying and how to stop it in school and online. Ed Henry, our senior White House correspondent, has more on that event.

ED HENRY, CNN SENIOR WHITE HOUSE CORRESPONDENT: President Obama using this first-ever White House anti-bullying summit as a forum to try to bring attention to this very, very difficult issue and say, look, for too long there have been students all around the country who have just accepted it, that they were going to get picked on, that they were going to be bullied, be the subject of assaults and violence and that it was sort of a rite of passage for kids. The president says that given all these tragic incidents where some kids have committed suicide over bullying, he says it's time for all of this to end, for schools to have higher standards. And he and the first lady have used various social media tools like Facebook to bring that message directly to students, to report some of these bullying incidents, for example. The president used his forum at the White House to say that even he as a kid was bullied.
U.S. PRESIDENT BARACK OBAMA: As adults, we all remember what it was like to see kids picked on in the hallways or in the schoolyard. And I have to say, with big ears and the name that I have, I wasn't immune. I didn't emerge unscathed. But because it's something that happens a lot, and it's something that's always been around, sometimes we've turned a blind eye to the problem. We've said, "Kids will be kids." And so, sometimes we overlook the real damage that bullying can do, especially when young people face harassment day after day, week after week.
HENRY: So the bottom line is, the key moving forward is going to be, will there actually be some action to back up some of the talk at this summit. Ed Henry, CNN, the White House.

Wisconsin Showdown
LANCE: The showdown in Wisconsin may be over. The anger is not. This started with Republican Governor Scott Walker's budget proposal that would limit negotiating rights for workers' unions. Fourteen Democratic state Senators fled the state so that there wouldn't be enough people there to pass the bill. On Wednesday, Republicans took out all the parts of the bill that had to do with the budget. Voting on non-budget bills requires less people, so the reduced negotiating rights passed. Protesters at the capitol yesterday started pounding on the windows. That forced police to put the building in lockdown! They closed the capitol and forcibly removed anyone inside who wouldn't leave. One entrance was re-opened later in the day.
Shoutout
THOMAS ANDRES, CNN STUDENT NEWS: Today's first Shoutout goes out to Mr. Govern's social studies classes at Riceville Community High School in Riceville, Iowa! What is the smallest type of bird? If you think you know it, shout it out! Is it the: A) Finch, B) Sparrow, C) Egret or D) Hummingbird? You've got three seconds -- GO! Hummingbirds are the smallest; even the largest variety is only about 8 inches long. That's your answer and that's your Shoutout!
LANCE: Imagine if the military had a vehicle that was as small as a hummingbird. Definitely wouldn't be able to fit a pilot in there. But that's actually the point. We're talking about drones, aircraft that someone flies by remote control. The U.S. military has used drones for years. Chris Lawrence is going to show us one right now that could bring big changes to the battlefield.
(BEGIN VIDEO)
CHRIS LAWRENCE, CNN PENTAGON CORRESPONDENT: Imagine a drone as small as a hummingbird; same shape, same sound. Wait, don't imagine. It's here in this California lab.
MATT KEENNON, AEROVIRONMENT PROJECT MANAGER: It looks more or less like an indigenous small bird, and it can fly through small clearings and through trees and seeing inside.
LAWRENCE: AeroVironment's Matt Keennon says this is how the bird sees us from above. Right now, the hummingbird can only fly a little bit longer than 10 minutes. But at that size, imagine what it could do in 10 hours. The Defense Department has spent $4 million with that dream in mind: American troops armed with an unmanned vehicle that blends into the other birds or insects in a given country.
KEENNON: The operator hovers the aircraft around until it finds an opening.
LAWRENCE: Perhaps even buzz into a room, drop a payload and leave. But most unmanned vehicles, the hummingbird included, still depend on man to control their cameras or movements.
LT. GEN. DAVID DEPTULA, U.S. AIR FORCE (RETIRED): But that's a vulnerability. That can be interrupted. That can be hacked.
LAWRENCE: Retired General David Deptula says future enemies will cut the operator's connection unless drones become more autonomous. He says sure, drones have worked in Iraq and Afghanistan, because there's very few missiles to shoot them down.
DEPTULA: But if you fly these same vehicles where there is an air defense, those MQ-1 Predators and MQ-9 Reapers would be falling from the sky like rain.
LAWRENCE: Compared to other drones, the hummingbird has a six-inch wing span and weighs less than a AA battery. But the designer needs to add intelligence to its small size.
KEENNON: It could be much more useful if the aircraft could keep itself safe.
LAWRENCE: If so, the military has designs beyond battle. It envisions the bird helping to find victims, weaving through crevices created by an earthquake.

Shoutout Extra Credit
TOMEKA JONES, CNN STUDENT NEWS: Time for a Shoutout Extra Credit! Under which president did the start of Daylight Saving Time in the U.S. move from April to March? You know what to do! Was it: A) George W. Bush, B) Bill Clinton, C) Ronald Reagan or D) Jimmy Carter? Rewind the clock to three seconds -- and GO! The shift happened in 2007 under President George W. Bush. That's your answer and that's your Shoutout Extra Credit!
Wakeup Calls
LANCE: That Daylight Saving shift comes this weekend. You might be losing an hour of sleep. But if you think that gives you an excuse to be late to school on Monday, school officials in Boston, Massachusetts are ready to give you a wake-up call! Some of the city's students who are late to class on a regular basis will hear the phone ring at 6:15 a.m. Might be your principal, might be a celebrity. But the message is simple: get up and get to school! The district says the goal is to keep students from falling too far behind. Some parents are okay with the wake-up calls. But others say the schools are overstepping their bounds.
Blog Promo
LANCE: So, whose responsibility is it? That's what we're asking on our blog. When it comes to making sure you're on time for school, is it on you, your parents, your teachers and principals? Share your opinions on our blog at CNNStudentNews.com!
Before We Go
LANCE: And finally, if leg of lamb sounds good to you, you're gonna love today's Before We Go segment. 'Cause we have 20! Five baby lambs, born on a farm in Canada. The owner says it's pretty rare. Sheep usually give birth to single lambs, maybe twins or even triplets. In fact, these little guys' mom has had triplets twice before. But quintuplets don't come along too often. We were hoping to get a reaction from the mama sheep, but she didn't seem too talkative.
Goodbye
LANCE: I guess she was just being sheepish. Hopefully, this isn't a hoax, because we'd hate for someone to pull the wool over our eyes. Ewe had to know that one was coming. Remember to set your clocks ahead this weekend. For CNN Student News, I'm Natisha Lance.

美国国会举行关于美国穆斯林极端化程度听证会
3月10日，在美国首都华盛顿国会山，众议院国土安全委员会举行关于美国穆斯林极端化程度的听证会。
奥巴马透露童年时曾被欺凌
美国总统奥巴马透露，自己在童年时亦是校园欺凌事件的受害人。
奥巴马在白宫出席防止儿童欺凌研讨会时，透露自己小时候都是受害人，他呼吁家长要多些关心子女，留意他们曾否被欺凌。奥巴马忆述自己童年的经历时指，曾经被人笑耳朵大及名字很古怪，心灵受创。他指童年阴影绝对会影响儿童的心路历程，提醒父母不要忽视。
美国过往几年都有少年不堪长期受到欺凌而自杀，奥巴马表示，欺凌事件不单止局限在校园，亦存在於手机通讯或者在网络世界。
奥巴马又指，估计美国有三分一中学及高中生曾经受欺凌，近300万个学生曾经被人欺负。加上社交网站兴起与手提电话普及，令小朋友更易受欺凌。
美科学家将研发微型机器雄蜂成为空军武库新成员
看起来像是未来游戏，但是这个场景来自于空军的动画视频：不明身份的歹徒被像鸟或昆虫般的微型机器人保持一定距离跟踪着。当其中的一个歹徒打开门的时候，一个微小的机器昆虫像车库门一样展开翅膀，变成了一个间谍。另外一个场景，一个小虫——空军称其为微型战机即（以下简称）MAV——爬到狙击手的藏身处向其后脑给予致命的一击。
这看起来好像不是很真实，但是美国空军高级官员相信在不久的将来MAV会成为美国国防部武器库中的重要组成部分。美国民间科学家与空军实验室的科学家们一道进行研究，预计将于2015年之前开发出第一代MAV。他们希望这第一组机器人能够像鸟一样大小并且能够不用充电工作许多天。
美国空军首席科学家Mark Lewis说：“这些将成为改变未来游戏规则的装置”。
十多年前来，美国五角大楼和空间工业向有关这些微型飞行器的研究投入了巨额的资金，官方认为他们在作战和营救行动中将会发挥不可估量的作用。
科学家们研究了果蝇的飞行、昆虫的爬行以及鸟的栖息，以寻找如何让飞行器变得很轻，足以装在士兵的背包里但却能够在空中停留足够的时间。
美国军方及其盟军已经在战场上运用过一些小型的设备，但是这些设备从大小到隐秘性都不能与空军实验室的科学家正在为未来研制的飞行器相提并论。
英国特种部队在阿富汗的侦察行动中曾经测试过一个名为“黄蜂”的长28英寸的MAV。去年美国海军订购了加利福尼亚AeroVironment 公司的价值19，300，000美元的微型无人飞行器，“黄蜂”上能够安装爆炸物，理论上讲能够被用于出其不意的突然袭击。
美国军方在伊拉克和阿富汗战场的侦察行动和斩首行动中利用了大型的无人飞行器。
美国莱克星顿学院的国防分析家，华盛顿的智囊团成员Loren Thompson说：“几十年来空军一直想要研制微型无人飞行器，它符合空军对于微型化趋势所作的一切努力。”
美国空间飞行器董事会的团队负责人Maj. Gregory Parker说，近期目标是在2015年前建造一个鸟一样大小的MAV，到2030年空军希望能够建造一个像昆虫一样大小的飞行器。空军科学家制作的商业宣传片是用来展示他们的构想的，他表示，“雄风”将会是“不显眼的，有渗透力的和致命的。”
但是美国空军和它的军工合作伙伴在开发下一代MAV的工作中面临着巨大的挑战。“黄蜂”在2002年的测试飞行中创造了在空中停留107分钟的记录—远低于空军研究实验室开发一个能够一次连续工作几天甚至几个星期的飞行器的目标。
Parker说，董事会正在寻找一种方法使得MAV的概念模型能够从城市中潜在的资源中获得能量，比如电线和阳光。另一个问题就是如何着陆。 Parker说：“最大的挑战在于如何让它能够机动的停在某一点上，它能够不需要跑道而着陆吗？我们必须设法找到如何在树枝或者房檐上着陆的方法，或者如何在电线上面着陆。”
空军军官称他们想像中的“黄蜂”应该足够的小，从而能够混杂于环境中，更加安全更加隐秘的窥视山口背面或者窥探可疑叛乱分子的藏身处来搜集情报。研究者也在努力研究能够使空军发射一群MAV从而提供更为密集的监视的技术。
Parker说：“也许你可以在一个街区发射许多飞行器而用来寻找一个（目标）。”
Parker还表示，轻型MAV也可作为民用。比如，小型无人飞行器可以被派往自然灾害发生的地区，从碎石中来寻找生命迹象。
美国国防部分析家Thompson说，鸟样大小和昆虫大小的飞行器将会用于伊拉克和阿富汗那样的战场中的战斗部队。他还说，建造能够可携带小型相机或者武器系统的微型飞行器的技术需要有重大的突破。“可能已经有了制造蝗虫大小的飞行器的技术，但是如果它不能够进行有效载荷的话，为什么还要造它呢？”
美国空间飞行器董事会代理董事Douglas Blake表示，虽然研究者们可能遇到了一些障碍，但是他认为他的团队有能力克服它们。他补充说，这在战场上的回报将是非常巨大的。Blake 说：“这将使我们具有在人事时间到达任何地点的能力。”
