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.
These years, there`s been a series of disasters like this.
Thousands of migrants have 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.
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.
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.
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.
How you doing?
Doing good.
Drew Griffin with CNN.
Nice to meet you, sir. This is Philippe Cousteau.
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.
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.
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.
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...
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.
And is this going to go on for years and years?
However long it goes on, the company is committed to cleaning up
that which is exposed and that which is Macondo oil.
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.
The philosopher and psychologist William James
is known for his theories surrounding emotion.
That`s your answer and that`s your Shoutout.
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.
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.
So your technology, how can it know what I`m feeling?
What is it looking for?
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.
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?
Technologically, it`s possible,
but we have crafted all our user experiences to date
so that we get this opt in beforehand.
What are some ways
that you`re already implementing this technology?
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.

Hello to Farnsley Middle School in Kentucky.
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.
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.
Still, don`t expect them to squid while they`re ahead.
Once researchers sushi potential,
the cephalapodsibilities are endless.
