CARL AZUZ, HOST:  Hi, I`m Carl Azuz.
Hope your week is off to a good start.
First  up today on CNN STUDENT NEWS, tragedy at sea.  Last week, hundreds of  people boarded a boat from Libya headed to Europe.  It sent out an SOS  on 
Saturday night and as a rescue ship approached, the  migrants moved toward it, crowding one side of their own boat, causing  it to capsize in frigid 
waters.
Italian Coast Guard officials say they`ve recovered some survivors, but hundreds of people are feared dead.
This  years, there`s been a series of disasters like this.  Thousands of  migrants h been rescued.  Hundreds have died in dangerous Mediterranean 
crossings on unsafe ships.
Some  are looking for a better life in Europe.  Some are running from  violence and instability in countries like Libya.  Some are being 
trafficked as slaves.
European leaders are holding emergency meetings and increasing the number of patrol ships to address the problem.
For  millions of Americans, the middle of April is a time of remembrance,  reflection and recovery.  Last week marked the anniversaries of the  Boston 
Marathon bombings and a shooting at Virginia Tech  University.  April 19th, 1993 was when the FBI led an assault using tear  gas on an armed religious 
cult in Waco, Texas.  It`s not  clear exactly how a fire broke out in the compound where the cult was  gathered, but dozens of people died.
On April 19th, 1995, a  massive bombing occurred at Alfred P.  Murrah Federal Building in the  Oklahoma capital.  The Oklahoma City National 
Memorial and Museum stands as a monument, with 168 stone and glass chairs representing each victim.
And  on April 20th, 1999, there was a shooting attack at Columbine High  School in Littleton, Colorado.  The Columbine Memorial, opened in 2007, 
pays tribute to the students and teacher who were killed.
April 20th is also the anniversary of a historic environmental disaster.

WOLF  BLITZER, HOST:  That massive oil slick now covering some 600 square  miles of the Gulf of Mexico and it could start reaching the United  States 
coast within hours.

Gulf Oil Spill:  Five Years Later
April 20, 2010
The Deepwater Horizon oil rig explodes
126 workers were on board
11 were killed
The explosion launched one of the worst environmental disasters in history
4 million barrels of oil flowed into the Gulf of Mexico over the course of nearly three months
Oil washed up on the shorelines of Louisiana, Mississippi, Alabama and Florida
Since 2010, BP has paid more than $13 billion in claims, advances and settlements and spent more than $14 billion on cleanup
Phillipe Cousteau
Today, the once-polluted waters look better
But the oil isn`t completely gone
(END VIDEO TAPE)
AZUZ:   Authorities knew it would take years to clean it all up.  Back in  April of 2010, the U.S. Coast Guard had estimated that 210,000 gallons  of 
oil a day were flooding out of the broken well into the  Gulf of Mexico.  The final U.S. government report on the spill put the  blame on the BP Oil 
Company, The Halliburton Oil Field Services Company and The Transocean Offshore Drilling Company.
BP  finally stopped the spill by putting an oil containment cap on the  leaking well and permanently sealing it off in early August of 2010,  more 
than two months after the deadly explosion.
You probably won`t see its effects on Gulf Coast vacation beaches, but it`s still washing up in other places.
(BEGIN VIDEOTAPE)
DREW  GRIFFIN, CNN CORRESPONDENT (voice-over):  Barataria Bay, Louisiana, the  marshes and the shores of these small islands were once covered in oil.   
Today, from our boat, we spot two dozen workers wearing face  masks, shoveling, working on a stretch of beach.  We pull up to take a  look.
(on camera):  How you doing?
UNIDENTIFIED MALE:   Doing good.
How are you?
GRIFFIN:  Drew Griffin with CNN.
Nice to meet you, sir.
This is Philippe Cousteau.
UNIDENTIFIED MALE:  (INAUDIBLE).
How is it going?
We have to have you stay away from the hazardous material at the moment, because it is a clean up site.
GRIFFIN  (voice-over):  The hazardous material turned out to be BP`s oil, a 90  foot long, 30,000 pound tar mat.  We had a small tar ball tested and it 
matched the oil from the spill.
(on  camera):  The fact is, five years later, there is still oil -- oil in  big enough clumps that it needs to be dug up by a crew like this,  digging 
down 30 inches, trying to take it and remove it.
GEOFF  MORRELL, BP, SVP, COMMUNICATIONS & INTERNAL AFFAIRS:  The pockets  of tar mats that still exist are in areas that are known to us, but  which were 
deemed by the federal government to be better to  leave alone there and let them be naturally exposed to er -- through  erosion and then for us to clean 
them.  So as they appear, we are finding them and removing them.  But none of them poses a threat to human or aquatic life.
GRIFFIN:  And is this going to go on for years and years?
MORRELL:  However long it goes on, the company is committed to cleaning up that which is exposed and that which is Macondo oil.

Shoutout
UNIDENTIFIED MALE:   Time for the Shoutout.
American scientist William James is known for his research into what subject?
If you think you know it, shout it out.
Is it emotion, speech, reflex or biology?
You`ve got three seconds.
Go.
(BELL RINGING)
UNIDENTIFIED MALE:  The philosopher and psychologist William James is known for his theories surrounding emotion.
That`s your answer and that`s your Shoutout.
AZUZ:   We`ve talked before how Internet companies like Google and social  media sites like Facebook use the sites you visit and the subjects you  like 
to help advertisers reach you.  It`s called data mining.
One  thing that`s new, technology that allows some computers to track your  emotions while you`re online.  One thing that`s not new, the privacy 
concerns.
(BEGIN VIDEOTAPE)
(ON SCREEN)
This technology wants to know what you feel
UNIDENTIFIED  FEMALE:   At Affectiva, we develop emotionally intelligent computers.   So we use technology that can track your facial expressions and 
we map that into a number of emotional states.  Essentially what the  computer is doing is tracking your main feature points, like your eyes, 
your mouth, your eyebrows.
UNIDENTIFIED MALE:  So your technology, how can it know what I`m feeling?
What is it looking for?
UNIDENTIFIED  FEMALE:   We`ve amassed the world`s largest emotion data repository,  about seven billion emotion data points.  We`ve collected 
videos from over 75 countries of people responding to digital content  and we use that to train the computer to detect all sorts of different 
expressions, from enjoyment to confusion, concentration.
UNIDENTIFIED  MALE:  One of the things that`s scary about this type of technology is  you think, wow, will a computer maybe be reading my emotions 
without me knowing?
Do you think that`s possible for this technology one day?
UNIDENTIFIED  FEMALE:   Technologically, it`s possible, but we have crafted all our  user experiences to date so that we get this opt in beforehand.
UNIDENTIFIED MALE:  What are some ways that you`re already implementing this technology?
UNIDENTIFIED  FEMALE:   So one of our main focuses at the moment is in the  advertising and media space.  We work with movie studios to develop and 
test their movie trailers.  Also, we work with about 1,400 brands and  advertisers who use our data because they want to understand the  emotional 
connection you have with a brand.  And we help them optimize their advertising.

Roll Call
AZUZ:   The site CNNStudentNews.com, the page, each day`s transcript.  The  school`s on today`s Roll, Osborn Middle School in the capital of  Arizona.  
That`s Phoenix, where The Fire Hawks are watching in The Grand Canyon State.
Gillette is a city in Northeast Wyoming.  It`s where we heard from Campbell County High School.  Their mascot is The Camels.
And in The Bluegrass State, we`ve got some Wildcats online in Louisville.  Hello to Farnsley Middle School in Kentucky.
Before We Go
AZUZ:   Except for maybe considering whether to order the calamari, most of us  don`t think much about squid.  But scientists are finding uses for  their 
proteins that could shape the future gadgets we buy, future technology in medicine and the future of camouflage.
(BEGIN VIDEOTAPE)
AZADEH ANSARI, CNN CORRESPONDENT:  Could one of nature`s masters of camouflage help disguise soldiers in combat?
Findings  from a recent research study from a team of scientists at the  University of California Irvine say they`ve been able to isolate a key 
protein in squid skin, which could one day help solids disguise  themselves at night, during combat, and effectively make them invisible  from infrared 
detection.
The unique light reflecting  protein is called reflectin.  Reflectin has enabled squid and other  Cephalopods such as octopus and cuttlefish to blend 
into their  environments for millions of years.  Researchers say reflectin is super  versatile and with the right mechanical or chemical stimulus can 
virtually be turned into any color.
Inspired,  researchers found a way to produce reflectin in the lab and create  invisibility stickers.  These stickers are essentially tape coated 
with films of protein.
The lab technology is still a ways away from being used on the battlefield.
(END VIDEO TAPE)
AZUZ:   Still, don`t expect them to squid while they`re ahead.  Once  researchers sushi potential, the cephalapodsibilities are endless.
We`ve got to squiddadle, but come back Tuesday for more deep sea in CNN STUDENT NEWS.
