  • Fridays are awesome. I`m Carl Azuz. Welcome to CNN STUDENT NEWS.

  • First up, should Scotland be an independent country from the United Kingdom?

  • Scottish voters will decide next week in a simple yes/no vote.

  • Scotland has been a division of the U.K. for 307 years.

  • But its independence movement said those days should be over, in part because it believes Scots, not the central U.K. government should be able to determine Scotland`s future.

  • Also, Scotland has a lot of oil. The independence movement says if it`s separated from the U.K.,

  • Scotland would be one of the richest countries in the world.

  • The U.K. says Scotland has only one tenth the oil that the independence movement thinks it has.

  • And Britain`s government has been begging Scotland to stay part of the union,

  • which Britain calls one of the world`s most successful unions.

  • There are a lot of unanswered questions, how would this affect Scotland`s economy,

  • what currency would it have, would it stay part of the European Union?

  • All of this will need answers if Scots choose independence.

  • Polls indicate the vote will be very close.

  • In West Africa, this year`s outbreak of Ebola virus is merciless.

  • That`s the world from the United Nations.

  • Liberia has been hit the hardest.

  • The hemorrhagic fever has killed at least 1200 people there.

  • Liberia`s finance minister says his country`s at war with an enemy it can`t see.

  • The nation`s health care system can`t handle it. Efforts to stop the virus from spreading aren`t working.

  • Here`s the way it`s supposed to work:

  • for every Ebola patient healthcare workers are supposed to keep track of every single person who`s had close contact with him.

  • If one of these contacts gets sick, he`s supposed to be isolated.

  • Then all of his contacts are followed until there are no more sick patients.

  • It`s called contact tracing, and it`s pretty simple, but it`s powerful, it helped put a stop to SARS and to smallpox.

  • But in many parts of West Africa, contact tracing is breaking down.

  • These slums are a big reason why.

  • In many parts of West Africa, streets have no names, people have no addresses, there may not be maps.

  • That means some contacts never get found.

  • Here`s why that`s such a problem.

  • A missed contacts can spread Ebola to other contacts and they`ll be missed, too.

  • That`s why the CDC says even one missed contact can keep the outbreak going.

  • By now in West Africa, there are entire chains of transmission that are invisible:

  • the computer databases that keep track of all these cases and contacts,

  • often they are not in such great shape.

  • One disease detective from the CDC working in Sierra Leone, she says the database there was in shambles.

  • The CDC has designed special software to keep track of these cases and these contacts and they are trying to implement it in West Africa,

  • but even that hasn`t gone smoothly.

  • All of these is starting to add up, and it has the World Health Organization really concerned.

  • Just the facts. Heroin is a highly addictive drug.

  • It`s legal for private use in most countries, including the U.S.

  • The National Institute on Drug Abuse estimates that about a quarter of those who try heroin once become addicts and become more likely to die from an overdose.

  • Withdrawal symptoms are intense and last for days.

  • They include body aches, vomiting, insomnia and intestinal problems.

  • Now, despite that, heroin us is rising in America.

  • The U.S. Attorney General calls overdose deaths from heroin and other painkillers an urgent public health crisis.

  • Communities and states from Virginia to Ohio to Louisiana are trying to fight a heroin epidemic.

  • It`s not just that one substance. It`s other opiates like it.

  • And man-made drugs like codeine oxycodone, hydrocodone, stuff that`s commonly prescribed for pain relief,

  • these all have similarities to heroin, and they all show the danger of addiction.

  • How do these chemicals affect the brain? One big way is by exerting powerful pain relief to the rest of the body.

  • Chemicals flood the system and match on to millions of opiate receptors peppered throughout the body.

  • Think of opiates in the receptors like puzzle pieces.

  • When they bind together, pain signals are dulled, or they go away altogether.

  • If the brain already has opiate receptors, doesn`t that mean it can naturally provide pain relief?

  • That`s right! Feel good chemicals like endorphins are natural opiates that dull pain and also give you a rush.

  • The problem with manmade opiates that mimic endorphins, take too many and they can overwhelm the system, give you too much of a rush.

  • That can lead to dependence or abuse.

  • Addiction become an even bigger problem, because opiates also slow down breathing and heart rate.

  • Mix them with other things that slow down your body, and everything could grind to a halt.

  • In fact, every 19 minutes someone dies of an accidental prescription drug overdose, most of the time, involves an opiate.

  • It`s now more common than dying in a car crash.

  • If you want to avoid that fate, don`t take more than you`re prescribed, don`t use other people`s prescriptions, never mix opiates with alcohol.

  • And maybe try other ways of alleviating your pain like over the counter pain relievers and good old fashion exercise.

  • When Dr. Leela Hazzah was a kid, her father told her that he used to hear lions roaring when he slept on the rooftop of their family home in Egypt.

  • She never heard it.

  • When her father told her it was because lions have gone extinct in Egypt, Hazzah knew what she wanted to do with her life.

  • 60 years ago there were probably half a million lions in Africa, today there is less than 30,000 lions in all of Africa.

  • If we don`t do something soon, there are going to be no lions left, maybe in ten, 15 years, who knows.

  • I spent a year living in the Maasai community to understand why people were killing lions.

  • I spent a year living in the Maasai community to understand why people were killing lions.

  • It brings a huge amount of prestige to the warrior and they were killing lions in retaliation for livestock that were killed.

  • They started opening up and telling me stories.

  • That`s when it clicked. If want to conserve wildlife we have to integrate communities.

  • Our organization hires Maasai warriors and it converts lion killers into lion guardians.

  • When we first hire lion guardians they don`t know how to read or write.

  • We provide all of that literacy training and the technical training.

  • They track lions so they can keep very accurate ecological data on lion movements.

  • The lion guardian model is founded on Maasai cultural values.

  • And it is just being tweaked a bit to the 21 century.

  • We never really even imagine that we could transform these lion killers to the point where they would risk their own lives to stop other people from killing lions.

  • When I first moved here, I never heard lions roaring. But now, I hear lions roaring all the time.

  • There`s one place we go to to find Roll Call schools, our transcript page at cnnstudentnews.com.

  • Three schools from yesterday`s transcript. Moundsville Middle School in Moundsville West Virginia. Good to see the Trojans watching.

  • Heights High School in Wichita, Kansas, we`ve got some falcons on the wing.

  • And Lowery Freshman Center in Allen, Texas, welcome to all of the Eagles in the Lone Star State.

  • NBA star Jeremy Lin likes a good prank. His wax figure recently appeared at Madam Tussauds Museum in San Francisco.

  • Except it wasn`t wax at all.

  • The 6`3`` point guard recently posed as a solid object, then when people approached, boo.

  • It looked so lifelike that because it is.

  • What`s cool is that once these people got over the initial jolt, they got to hang out with Jeremy Lin.

  • Assuming they didn`t make a fast break, they didn`t dunk out,

  • they weren`t total basket cases, and they were able to rebound afterward.

  • they weren`t total basket cases, and they were able to rebound afterward.

  • The prank, and that`s a lot of it, tension, that`s kind of a field goal of it, whether Lin`s victims like it or not.

  • I`m Carl Azuz. That`s your Friday show. We all wish you a great weekend, of court.

Fridays are awesome. I`m Carl Azuz. Welcome to CNN STUDENT NEWS.
