CARL AZUZ, CNN STUDENT NEWS ANCHOR: Hi! We’re launching a special edition of CNN Student News this week. As the space shuttle program wraps up, we’re taking a look back – and a look forward – at NASA’s space program.
First Up – Last Shuttle Launch
AZUZ: The U.S. has been launching shuttles for 30 years. They are the world’s first re-usable spacecraft. They launch like a rocket and land like a plane.
Atlantis, Challenger, Columbia, Discovery and Endeavour: These five orbiters have launched more than 600 astronauts into space. This video you’re seeing right here highlights some of their achievements.
Over the course of 134 shuttle flights, these crews have logged millions of miles in space and carried thousands of tons of cargo. The space shuttle has served as America’s main transport for crews and supplies to the international space station. Shuttle crews have also repaired space equipment, like the Hubble Telescope. They’ve launched new satellites, and they’ve done experiments that can’t be done on Earth.
When the shuttle was first announced, the idea was that shuttle launches would be cheap enough to happen every week. But it actually costs about half a billion dollars to launch a shuttle, and NASA only ever planned a few missions each year.
So, what’s NASA’s plans for the shuttles’ retirement? Each one of them will become an exhibit in museums across America. So maybe one day, you might even get to go inside one.
Now, we’re going to hear from someone who not only gets to go inside a shuttle, he gets to fly in one too: the commander of Atlantis’s latest mission, speaking a few weeks before the last scheduled mission.
CHRISTOPHER J. FERGUSON, ATLANTIS COMMANDER: I don’t think that the full magnitude of the moment will really hit us until the wheels have stopped on the runway. I’m not sure words will really be able to capture — for the crew and for the entire shuttle work force — just how much the shuttle program has meant to us for the last 30 years.
Shoutout
CHERYL CASTRO, CNN STUDENT NEWS: Time for the Shoutout! Which constellation is named for a hunter in Greek mythology? If you think you know it, shout it out! Is it: A) Capricorn, B) Orion, C) Ursa Major or D) Scorpio? You’ve got three seconds — GO! Orion is the mythological hunter who can also be found in the stars. That’s your answer and that’s your Shoutout!
AZUZ: Orion is also the name of a new program at NASA. It’s expected to be the replacement for the space shuttle program. Americans could be headed back to the moon or into deep space toward Mars. Now, those missions are a long way off. Part of the Orion program did go on the road recently though, and WTXL reporter Greg Angel got a chance to check it out.

DMARCUS MCDONALD, STUDENT: It flies into space and looks at stars or moons or other planets.
GREG ANGEL, WTXL REPORTER: Dmarcus McDonald is talking about Orion. This capsule, touted as the future of NASA, expected to one day carry man into deep space.
CHARLES OHBAUGH, NASA ASTRONAUT: What this vehicle will allow us to do is hopefully go beyond lower Earth orbit, on to the moon and hopefully to Mars, ultimately, is our goal.
ANGEL: But 34 million miles from Mars, here on Earth, Orion is getting a lot of attention during this special stop in Tallahassee. Dee Arnold drove in from Valdosta, Georgia to check it out before Orion is taken to its final destination at Kennedy Space Center.
DEE ARNOLD, VALDOSTA, GEORGIA: I just like things that go on with the space program, and I just think it’s awesome. I just wanted to see the next thing that NASA was going to do, the next part of space explorations.
NASA ANNOUNCER: Three…two…one…launch!
ANGEL: The Multi-Purpose Crew Vehicle, as it’s called, will likely be in line to replace the shuttle program.
LINDA SINGLETON, NASA: We’re excited and very passionate about the work we do on this program, and we hope to launch our first orbital test flight as early as 2013, so we’re ready to get on with the next program.
ANGEL: While there’s still a lot of work to be done, according to NASA, this spacecraft should eventually be capable of sustaining a crew of up to six astronauts on deep space missions that could last anywhere from six days for a lunar fly-by, to up to 900 days for a Mars exploration mission.

AZUZ: There’s debate among scientists on this issue and we know you’ve got some opinions on it, too. Where should America go next? To the moon? Trips to Mars? Somewhere else? Or should we just stay home? Send us your thoughts about the end of the shuttle program and the start of the next space program on our blog. You’ll find that at CNNStudentNews.com.
Goodbye
AZUZ: Before we go, the shuttle program may be on its last Endeavour. And NASA’s not likely to find the lost continent of Atlantis. But that doesn’t mean the agency isn’t going to be looking for its next Discovery. So, while NASA moves forward, we’ll leave you with a look back. We hope you’re enjoying your summer so far. For CNN Student News, I’m Carl Azuz.

THIS IS A RUSH TRANSCRIPT. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED.
TOMEKA JONES, CNN STUDENT NEWS: That airplane means it’s time for a new summer edition of CNN Student News! Hi, everyone. I’m Tomeka Jones. And this week, we’re focusing on connections; specifically, Career Connections!
JONES: That’s the name of a segment we debuted this past school year. The goal of Career Connections is to give you guys a look at some of the different jobs around CNN. But first, we want to look at jobs in general. You definitely want to take notes for this! Candice McLemore is here to give us some career advice from a recruiter’s perspective.
Hi, Candice, thank you so much for joining us!
CANDICE MCLEMORE, PROFESSIONAL RECRUITER, TURNER BROADCASTING, INC.: Thanks for having me.
JONES: First question: What exactly does a recruiter do?
MCLEMORE: A recruiter basically has the role of finding qualified and talented employees for a company.
JONES: Can you share with our audience, which is a middle and high school audience, a few dos and some don’ts on how to put together a resume?
MCLEMORE: Sure. I would say in terms of dos, first of all, pick a very simple format. You don’t have to get elaborate; you don’t want to use a lot of different fonts or colors or fancy items on your resume. You want somebody to be able to view it very quickly and to understand what your skills and your qualifications are.
And secondly, in terms of the content, I would say really think about what are the qualities and qualifications that you have. Certainly you can list job duties that you’ve had at previous companies, but you also want to think outside the box in terms of accomplishments as well. Did you solve a particular problem? Did you win an award? Were you on a particular dean’s list or things like that? Try to think about other accomplishments that you can encompass, and then also other involvement that you’ve had outside of the work world as well. So, think about volunteer organizations that you’ve been a part of. And then also, certainly, any technical systems or software, things like that, that you may know how to use, even if you’ve used it in your personal space and not professionally. If it’s a skill that you have, you should include that on your resume.
JONES: OK, my last question: speaking to that middle or high school student, what tips and tricks maybe you can provide for them to get ahead of the competition?
MCLEMORE: I would say for them to get ahead of the competition, to really get involved either in their school, in organizations or on their campuses when they go off to college. One of the things that our company looks for for our interns is people who are really passionate about what we do, but have also put that in to practice in any way that they can. So, if they want to be a publicist, they’re on the PR committee for their student organization, or their sorority or whatever it may be. They’re not just going to classes. They’re doing more and taking more time to get exposure in any way that they can, even in their extracurricular activities.
JONES: Don’t put away that pen and paper yet! A few CNN professionals also have some great advice to share. They talked about their jobs in Career Connections segments last school year. If you missed those reports, go to CNNStudentNews.com to check them out. In the meantime, here’s what those employees had to say about how to get a jump start on your career.
(BEGIN VIDEO)
SUMMER SULEIMAN, CNN VIDEO JOURNALIST: It’s definitely OK not knowing exactly what you want to do and saying "this is what I want to be in ten years." The best part is the journey there allows you to experience and try different things until you find what really works for you.
MONIQUE SMITH, CNN PRODUCTION ASSISTANT: The advice that I would give is if your school has a broadcasting program, make sure you are in that program. Find out what your passion is, because whenever you find out something that you really feel strongly about and you have a good background in it, whatever you decide to do it won’t feel like work. It will just feel like something that you’re doing for fun because you’re interested in it.
JAMES CURRY, CNN INTERNATIONAL PRODUCER: One of the best pieces of advice I was given is treat every job like you’re running for political office. That doesn’t mean go shake hands and kiss babies and all that kind of stuff. It just means get your name out there, let people know you’re interested and pursue it, and don’t stop.
STEPHANIE TODD, CNN EXECUTIVE PRODUCER: Being proactive, I think, in any field is the way to go, and having ideas and not being afraid to speak out and being confident in yourself. You shouldn’t get discouraged by if someone gives you some sort of criticism or critique or feedback. You just have to know that you believe in yourself and you’ve done your best.
JOE CARTER, HLN ANCHOR/REPORTER: You have to have passion in everything you do. Doesn’t matter if it’s at work or at home or at school, you have to have passion. You have to come with energy and excitement. Persistence, because there is another person willing to take it from you if you don’t keep pushing forward. Patience, which is it doesn’t all come at the beginning. It takes time, actually, to get where you want to be. It doesn’t happen overnight. And positioning, so every day you wake up you’ve got to think about how you can better yourself for tomorrow.
AMBER LYON, CNN CORRESPONDENT: A lesson to everybody, whether you’re a journalist or any other type of career, is be willing to take risks. Because if you’re truly passionate about it, follow your passion and success will follow. It will pay off in the end.

Blog Report
JONES: So, are you connecting with any specific career yet? We asked you guys that question on our blog last year. Some of you may have changed your minds, and that’s okay. But here’s what a few of you had to say then. Caitlin said she wants to be a second grade teacher. She says it’s easy for her to learn about this career. All she has to do is observe her current teachers. Coleton dreams of becoming an archeologist so he can make important discoveries. On the other hand, Tyler said he wants to be a kid a little longer and do the stuff as a kid he won’t do as an adult. He said sometimes you have to slow down. Kassandra and Olivia have something in common: they both want to be veterinarians when they get older. And Gavin believes that no matter how young you are, it is never a bad idea to give some thought to your possible profession. He says in these economic times, good jobs are hard to find.
Blog Promo
JONES: Some of you might be spending your summer working. Well, whether you’re interning with a company or just plain old having fun, we want you to tell us about it! There are two ways you can do it: write on our blog or send in a video. You have to at least be 13 to do that. You can do both at CNNStudentNews.com.
Goodbye
JONES: We’ve finished the job for now, but we’re already working on our next summer show. Be sure to recruit your friends to tune in next week. For CNN Student News, I’m Tomeka Jones.
When miscarriage isn’t a fluke
Posted on Jul 18, 2011 02:08:48 PM
(CNN) — As part of the Catholic wedding vows they took four years ago, Melissa and Jacob Arnold promised to be "open to children."
Choosing not to use birth control, the couple dreamed of having a large family. Six months later, Arnold’s period was late.
"One day at work, a friend came up to me and said, ‘I’ve got a bun in the oven!’ " Arnold says. "I thought, ‘Maybe I do too!’ So I ran home at lunch to take a pregnancy test. My husband read it and said to me, ‘You’re going to be a mommy!’ We were so thrilled. I ran back to work and said, ‘Guess what, I’m pregnant, too!’ "
But Arnold, who was 23 at the time, wasn’t going to be a mother, at least not yet. When she was eight weeks pregnant, she miscarried. A few months later she was pregnant again, and again she miscarried, this time at 10 weeks.
Finally, she had a healthy baby girl, but then she miscarried twice more, including one pregnancy with twins. In all, Arnold had four miscarriages, losing five babies in less than three years.
"I read a lot of books, and I learned there are tests you can do to see if there’s a reason you’re having a lot of miscarriages," she says. "But my doctor said the miscarriages were just nature’s way, and we didn’t need to do any testing."
Her doctor told her it was inappropriate to do testing until she’d had three consecutive miscarriages without a live birth. By this time, Arnold was feeling defeated, and her marriage was strained.
"I was so bitter and angry, I couldn’t even cry after I lost the twins," she says.
"This can be very frustrating for patients"
There’s no consensus among doctors about when miscarriages go from being a fluke that most likely won’t happen again to being a pattern that needs investigating. This can leave many patients like Arnold at a loss for what to do.
In 2001, the American College of Obstetricians and Gynecologists devised guidelines for doctors on how to manage recurrent pregnancy loss, but the group rescinded those guidelines last year and has not replaced them, according to Greg Phillips, a spokesman for ACOG.
"This can be very frustrating for patients," says Dr. Elwyn Grimes, professor of obstetrics and gynecology at the University of North Texas Health Science Center in Fort Worth. "There’s no easy answer. I tell patients to go on the Internet and do their own research and lay it all on the table for the doctor, and to just persevere finding a doctor who can help them."
Melissa’s story
Dissatisfied with her obstetrician’s response, Arnold set out to find a doctor to do testing to find a cause for her miscarriages. She says doctor after doctor refused, citing the same three-consecutive-miscarriage "rule."
"This theory about three consecutive miscarriages was promulgated back in the 1930s, based on no evidence and no research," Grimes says, adding that even so, there are still doctors who believe it.
After asking her family to pray for her, Arnold contacted Darci Klein, another woman who suffered recurrent miscarriages and wrote the book "To Full Term." Klein encouraged her to keep looking for a doctor who would do testing.
It was especially urgent, as Arnold had just found out she was pregnant again.
Finally, her phone calls worked: She found a doctor who would do the testing in Houston, not far from her home in Spring, Texas.
"The nurse told me to come in, and I said, ‘You mean, you’re going to accept me as a patient?’ and she said, ‘Yes, sweetheart. Something’s wrong. It’s not normal to have four miscarriages, especially at your age,’ " Arnold remembers. "I cried out of relief and happiness and hope for this baby I was carrying."
That doctor found that Arnold carried a genetic mutation that some researchers say is linked to miscarriages. She was prescribed baby aspirin to prevent clotting.
On Monday, Anthony Arnold was born full term, weighing 6 pounds, 12 ounces.
"I was very grateful that Darci encouraged me to fight," Arnold says.
Miscarriages often a random event
Many times when a woman has a miscarriage, it truly is a roll of the dice — an unfortunate event due to a chromosomal abnormality that’s random and not caused by any defect in the mom or dad. There’s no treatment for such events, and patients are encouraged to try to get pregnant again.
In fact, before six weeks, 70% of all miscarriages are associated with random chromosomal abnormalities, according to Dr. Mary Stephenson, director of the Recurrent Pregnancy Loss Program at the University of Chicago.
That number goes down to 50% of miscarriages between six and 10 weeks, and 5% of miscarriages after 10 weeks.
Tests after a miscarriage
Not only is there controversy about when to test, but also what testing should be done on women who’ve had miscarriages, and what treatment, if any, should be given based on the results of those tests.
After a woman miscarries, some doctors suggest that a chromosomal analysis be done on the fetal tissue to check for abnormalities.
Here are diseases that can be checked for in the mother, and sometimes the father, too. The American Society for Reproductive Medicine has a good overview.
Clotting disorders
Some clotting disorders, such as factor V Leiden and antiphospholipid antibodies, can put women at a higher risk for pregnancy loss. For a list, see Clot Connect, run by Dr. Stephan Moll, a hematologist at the University of North Carolina School of Medicine.
Hyperthyroidism
It may be harder for women with hyperthyroidism to become pregnant. The Columbia University Medical Center has more information.
Uterine abnormalities
Fibroids and other problems with the uterus or cervix can cause miscarriage, according to the March of Dimes.
Hormone imbalance
If progesterone levels are too low early in pregnancy, miscarriage can occur. The American College of Obstetricians and Gynecologists has more information.
Other medical conditions
Women with conditions such as kidney disease, diabetes and lupus may have a higher chance of miscarriage, according to ACOG.
CNN’s Sabriya Rice and John Bonifield contributed to this report.
Important Things About Surgical Solutions For Hemorrhoids And Their Outcomes
Posted on Jul 18, 2011 02:00:19 PM
You have many variants and intensity stages of hemorrhoids requiring different hemorrhoid treatment. For those cases where the hemorrhoids are especially bad, medical procedures may possibly be the most suitable treatment method for treatment of hemorrhoids. Of course, what is perceived as bad for one person may not be thought of as quite so bad for another. Generally, if the anal orifice is thoroughly covered with hemorroids that can be thought of as bad. More specifically however, thrombosed hemorrhoids in addition to bleeding hemorrhoids are typically instances whereby you should probably have a hemorrhoid treatment involving medical procedures.
The remainder of this writing will cover the varieties of hemorrhoid cures that involve medical procedures . Several of the earlier variants of medical procedures are extremely uncomfortable and they are generally known to take a considerable time to go away.

If you are taking into consideration medical procedures for a hemorrhoid home remedy . read through the rest of this writing to learn what cures out there.
Of the many varieties of hemorrhoid medical procedures out there, Rubber Band Ligation is among the most well-known. With this type of operation a rubber band about 1/25″ is pressed tightly upon the base of the hemorrhoid. The problematic arteries that make up hemorrhoid eventually shrivel up and fall off mainly because the oxygen supply to them is stop. It typically takes about few days give or take for the hemorrhoid to die.
Laser surgical treatments is one more treatment for the ridding of hemorrhoids. A specialised type of laser light is aimed straight into the hemorrhoid. Subsequently the hemorrhoid is actually burned off of the anal orifice instantly. This process is usually carried out without the need of being admitted to the hospital. In addition the potential concerns of medical procedures for example bleeding are lowered mainly because the hemorrhoid is cauterized using this method.
A Stapled Hemmorhoidectomy is a fairly widely recognized type of hemorrhoid surgical treatment . This type of medical treatment can help stop hemorrhoids from bleeding which eventually minimizes most of the pressure produced by the blood clots. This process is predominantly used on prolapsed hemorrhoids but it will work pretty well for any type of bleeding hemorrhoid. The technique calls for stapling the hemorrhoid.
Hemorrhoidal Artery Ligation Operation sometimes known as HAL is a more sophisticated type of hemorrhoid treatment that involves medical procedures. It is gaining popularity since it doesn’t generate an excessive amount of pain. Simply speaking the technique consists of discovering all the arteries that are providing the hemorroid with blood. After the arteries are selected they are stitched to stop the blood flow to the hemorrhoid. For this reason the hemorrhoid whithers and falls off leaving a very small scar..
A Instructive Assessment Of Thrombosed Hemorrhoids
Posted on Jul 18, 2011 01:00:19 PM
Thrombosed hemorrhoids are simply speaking, hemorrhoids where the blood vessels have clotted blood. The explanation of thrombosis is: the formation of a blood clot inside of a vein.

Whether or not internal or external hemorroids, you ought to get them cleared up right away. Thrombosed hemorrhoids pretty regularly develop into bleeding hemorrhoids that may get infected which may, in turn, result in blood poisoning which might be lethal.

Just How Can I Find Out Without A Doubt Whether Or Not I Currently Have Bleeding Hemorrhoids?
Posted on Jul 18, 2011 12:00:19 PM
Bleeding hemorrhoids are a pain in the buttocks., they can produce unbearable discomfort.But even, they can frighten the sufferer terribly if they’re un-aware of what is occurring. Though they may be somewhat scary, bleeding hemorrhoids in fact aren’t life threatening. Hemorrhoids are veins inside of the anus that have been through an extreme amount of pressure, chiefly when passing solid waste. What happens is the veins enlarge then as a result the blood will begin to clot. This causes bulbous veins which can sometimes pop. If they do pop that causes your anus to bleed a fair amount.

A common hemorrhoid treatment choice for bleeding hemorrhoids would be the stapled hemorrhoidectomy.

This hemorrhoid treatment choice is usually used to treat prolapsed hemorrhoids, but works on just about all bleeding hemorrhoids. Another hemorrhoid treatment is called hemorrhoidal artery ligation, which employs a proctoscope.
