CARL AZUZ, CNN ANCHOR:  Welcome to ten minutes of current events with no  commercials.  This is CNN STUDENT NEWS.  I`m Carl Azuz.  Thank you for 
watching.
First  up, President Obama made a promise yesterday to U.S. troops.  He says  he won`t get them involved in another ground war in Iraq.  Several  hundred 
American servicemen and women are in the region.   Their missions include launching airstrikes against the ISIS terrorist  group, gathering 
intelligence about ISIS, and training and helping Iraqi forces fight ISIS.
The  Obama administration says U.S. troops themselves will not be going in  the combat.  But the nation`s highest ranking military advisers says if  he 
thinks U.S. troops should get involved, he`d recommend it to the president.
Well,  some lawmakers have questions about the roles of U.S. troops in Iraq,  there`s another issue to be considered as the U.S. leads the way in 
fighting ISIS.  Money.
(BEGIN VIDEOTAPE)
CRISTINA  ALESCI, CNN CORRESPONDENT:  The bill from military operations in Iraq  keeps rising.  On August 29, the Pentagon said the mission is costing 
United States $7.5 million a day, a relatively tiny sum compared to the  billions spent in Iraq during our last campaign in the country.
But  what started as an effort to protect American interest in Iraq from  Sunni militants, is now morphing into something much bigger.  The U.S.  has 
completed over 150 airstrikes that started in August.  And  since the Pentagon released the daily average spending figure,  President Obama 
authorized additional military personnel twice.  He also opened up the possibility of airstrikes outside of Iraq.
BARACK  OBAMA, PRESIDENT OF THE UNITED STATES OF AMERICA:  We will hunt down  terrorists who threaten our country wherever they are.  That means I  will 
not hesitate to take action against ISIL in Syria as well as Iraq.
ALESCI:   On top of that, the president is hoping Congress will authorize $500  million request he made in June for training and equipping the rebels 
in Syria to fight ISIS.
Currently,  the U.S. is financing its involvement in Iraq through an $85 billion  allocation in the Pentagon`s overseas contingency operations 
account.  That money had been financing troop grow down (ph) in  Afghanistan and other activities in the region.  And the president says,  he does not 
need extra authorization from Congress.
To  be sure, the scope and strategy of U.S. involvement in Iraq today is  very different than during operation Iraqi Freedom from 2003 to 2011.   For 
one, at its peak, there were more than 150,000 troops on  the ground that needed housing, logistical support and supplies.  An  estimated price tag 
for that war by the congressional research  service is $806 billion.  Now, that doesn`t include interests on the  debt to fund the war or billions more 
for continued veterans care.  It`s important to remember, it wasn`t expected to cost that much.
In October 2003, six months after operation began, the CBO estimated Iraq would cost 85 to 200 billion dollars through 2013.
Estimates that were way off.
With  Obama`s latest announcement, the U.S. military will have approximately  1500 personnel in Iraq.  Now, more people means more money, so we`ll  have 
to see how high the figures go from here.

AZUZ:  Time for the Roll Call.  All three of these schools requested a mention on yesterday`s transcript at cnnstudentnews.com.
James  M. Bennett High School is present in Salisbury, Maryland.  The Clippers  send the competition sailing.  Jumping south to Fort Lauderdale, 
Florida.  And sending a shoutout to all of the raiders at St. Thomas  Aquinas High School.  And in the South Dakota City of Bonesteel, it`s  great 
to see the Cougars of South Central Middle School.
There  are a few different definitions for computer hacker.  One is someone  who`s really skilled in computer programming.  One is someone who tries  to 
break in and protect its systems.  And then there are  ethical hackers.  These are people who aren`t intending to steal  information like credit card 
numbers.  They are employed to  hack in the systems, to show a company or government where its networks  are vulnerable, how they can be broken into.
Ethical hackers can make over $100,000 a year while keeping criminals from steeling a dime.
(BEGIN VIDEOTAPE)
JAKE  TAPPER, CNN CORRESPONDENT:  You might think that the government takes  your information, your personal data very, very seriously and safeguards  
it, but if you think that you are wrong.
We have been  talking to two ethical hackers who have found major security  vulnerabilities in 50 universities, more than 100 schools and more than  20 
government agencies, hundreds of thousands, if not millions of incredibly sensitive files.  So how did this happen?
In  2012 Oracle told its customers we have this vulnerability.  Use the  security patch and these government agencies and schools and  universities 
didn`t apply it.  So, this big security hole exists there and now bad guys can access it too.
What  kind of information are we talking about?  Really, it`s the most  sensitive information that anyone who traffics an identity theft might  be 
very eager to get their hands on.  Dates of birth, Social  Security Numbers, addresses, parents` information, court documents in  some cases, grades, 
transcripts, medical information.  For  students, you can see where exactly the bus routes are to pick up and  drop off the kid.  It`s really the kind 
of information you don`t want anyone to know.
So,  what can be done about it?  Already these ethical hackers working with  the FBI have alerted three of these schools and government agencies as  to 
what happened, and they have fixed the patch, although I  have to say, one of them was a major court authority, and for a month,  the names of Defense 
Intelligence Agency agents and diplomats  and State Department employees, all their information was sitting there  on this port server for anyone to 
get, although now it is closed.

AZUZ:   Next time you get a mosquito bite, you`d be perfectly correct in  saying "She got me."  Why she?  Because only female mosquitoes bite, the  
males eat flower nectar.  Now, that`s random.
Sustainability  is a word you here discussed a lot, it`s defined as something like a  building, for example, that doesn`t harm the environment 
or use up too many natural resources. 
But while going green is intended to be good for natural surroundings it comes in an additional cost.
(BEGIN VIDEOTAPE)
RACHEL  CRANE, CNN CORRESPONDENT:  We are producing more waste and using more  energy than ever before, and it`s actually buildings that are in large 
part to blame.  They use 70 percent of the nation`s electricity and are responsible for 40 percent of carbon dioxide emissions.
But  here in Seattle, one building is trying to change that.  By pushing the  envelope with green technology.  This is the Bullitt Center, the  greenest 
commercial building in the world.
DENIS  HAYES, PRESIDENT AND CEO, BULLITT FOUNDATION:  When people do bold  things and buildings, they try to do one thing bold, they cover the roof  
with solar.  They have something that`s collecting rainwater.   They use really interesting building materials.  We jumped in and did  it all.
CRANE:  The six-storied Bullitt Center combines all of  these green technologies to achieve net zero energy and water used,  receiving countless 
awards as a result, and now they are  pursuing the most rigorous performance standard in sustainable  construction:  living building certification.
HAYES:  Living building is sort of like an organism.  It automatically tries to rebalance and keep everything well.
CRANE:   To regulate temperature, the building`s brain can sense weather  conditions and will automatically open and close the windows.  When it`s  
bright, the shades come down, even tilting at the appropriate  angle.  Integrating all these technologies isn`t cheap.  All in, the  price tag to 
build the world`s greenest commercial building was about $30 million.
(on  camera):  When you are looking at a balance sheet, it doesn`t always  make economic sense to create a sustainable green living building.
HAYES:   This building did cost (ph) us premium.  It costs almost 25 percent  more than a standard Class A office building.  But it`s the first.  The 
first of anything is more expensive.
CRANE (voice over):  The building`s tenants range from engineering firms to lawyers and contractors.
MICHAEL  DIX, FOUNDER, INTENTIONAL FUTURES:  Everyone here gets excited about  the fact that we are having a positive impact on the world around us.
HAYES:   People are becoming very aware of the fact that their employees are  most productive when they get access to fresh air and access to  sunlight.
CRANE (on camera):  And yet we are standing on the floor that`s empty right now.
HAYES:   But we`ve got a building that is 85 percent leased one year from the  opening date.  We are the first to have done something that is an 
essential part of the sustainable human future.

AZUZ:   All right, when I was told our last story would be about a  Siphonophores, I was like what?  The most common one we`ve heard of 
Portuguese man of war.  This is not a common one.  It`s a purple  species of Siphonophores, an extremely rare one found by Marine  biologist during a 
deep sea expedition.  It`s probably best  described as a colony.  Some parts of its catch pray, some swim, some  digest food.  They compose one strange 
looking sea creature.
But  how do you make puns on that story?  I mean talk about brain, a rare  animal to the Siphonophore front, mention its environmental creature 
comforts, say scientists really had to dig deep to identify it, my  producer didn`t think I can make any - I was able to siphon off for.   I`m Carl Azuz
