CARL AZUZ, HOST:  Hope you had a great weekend.  If not, there`s always next weekend.

First  up this April 13, Kenya is building a wall.  It will stretch 435 miles,  roughly the span of the country`s border with Somalia.
Kenya is  also reportedly telling the United Nations to relocate the world`s  largest refugee camp.  It`s in Kenya.  It contains 600,000 Somalis.   Kenyan 
officials want it moved to Somalia, though the U.N. says it hasn`t gotten an official request.
All  this has to do with security.  Kenya says it has to change the way the  U.S. did after the September 11, 2001 terrorist attacks.
The  Al-Shabab terrorist group is based in Somalia.  Kenya believes its  operatives crossed the border into Kenya, possibly filtering through the  
refugee camp before targeting Christians and killing 147  people at a Kenyan university earlier this month.  Al-Shabab also  claimed responsibility for 
an attack in 2013.  It killed 67 people in Kenya`s Westgate Shopping Mall.
Here`s a look at how porous the border is between Kenya and Somalia.
(BEGIN VIDEOTAPE)
NIMA  ELBAGIR, CNN CORRESPONDENT:  This is the border between Kenya and  Somalia.  Now, we can`t show you this for security reasons, but either  side 
of this border is a pretty substantial security setup.   And that has only grown in size and scrutiny in the aftermath of of the  Westgate attack in 
Nairobi.
(voice-over):  But this  isn`t the only route into Somalia.  Hacked out of the undergrowth, this  is where traffic flows -- the pioneer routes, so-
called rat routes, used by smugglers to cross back and forth undetected.
Branching  brazenly off from the government roads, they`re certainly a smoother  ride.  In spite of the Kenya government`s efforts to beef up 
border security.
(on  camera):  Up through these smugglers` routes, we`ve managed to enter  Somalia from Kenya without any checkpoints, without being asked for ID, 
without seeing any sort of government presence.
(voice-over):   Night falls and it`s rush hour on the pioneer routes.  People and  goods ferry back and forth.  Everyone is too afraid to stop for 
long here, even to help the stranded families we see along the way.
Many are escaping the uncertainty back home in Somalia, but some are seeking to enter Kenya undetected for their own ends.
The  pioneer routes end in the Dadaab Refugee Camp.  Authorities believe  that during the buildup to Westgate, Al-Shabab operatives traveled from 
Somalia through the pioneer routes and hid among the refugees in the  camp.  And it`s from there, the Kenyan authorities say, that they and  other 
undocumented people made their way through government checkpoints and deeper into Kenya.

AZUZ:   For the first time in 50 years, the leaders of Cuba and the U.S. sat  down together for meaningful talks on Saturday.  The two governments are  
working toward normalizing relations that have been largely cut off since the cold war.
President  Obama says it`s time to try something new, though some U.S. lawmakers  criticize him for engaging what they see as a corrupt government.
On  the Cuban side, President Raul Castro said there could be some  stumbling blocks in repairing ties, but they could be overcome.
One  complication, Venezuela.  It`s an ally of Cuba, but a rival of the US.   And Venezuelan President Nicolas Maduro said he respected, but didn`t  trust 
President Obama.
All of this happened at the  Summit of the Americas, a meeting of Western Hemisphere leaders.  The  location for this year`s event was Panama.
(BEGIN VIDEOTAPE)
ROSA  FLORES, CNN CORRESPONDENT:  The Panama Canal is an engineering marvel  that connects the world through a series of gates and locks.  It`s been 
bringing in about $2 billion worth of revenue since 2010 and profits  are expected to double with the addition of a deeper, wider, bigger  third lane 
of traffic.
As it stands today, about  14,000 ships cross through the canal every year.  And hear this -- about  60 percent of that traffic either starts or ends at 
U.S. ports.
Ships  are loaded with about 4,500 20 foot containers.  Now, fully loaded  container vessels take about eight to 10 hours to cross the 15 mile  canal.  
And hear this, they pay about $450,000.
The expansion is set to be completed in 2016, accommodating post-Panamax ships.  Now these vessels hold about 13,000 containers.
It  will take those vessels about 14 hours to cross the canal.  No word yet  on the additional cost.  But here is what we do know.  Before those  post-
Panamax ships can cross the canal, a lot of work needs to  be completed, creating a new 6.1 kilometer Pacific Access Channel,  deepening of the 
Pacific and Atlantic entrances and perhaps  what has captivated most people is the new system of locks and gates,  requiring more than four million 
cubic meters of concrete,  which is poured by thousands of workers.  And 16 gates -- those were  built in Italy.  The tallest of those, 11 stories high.
The  expansion will cost more tan $5 billion and it will take more then eight  years to complete -- an engineering wonder that makes the world a 
smaller place.

AZUZ:   We`ve reported on two Republican candidates who`ve entered the 2016  presidential race so far.  Yesterday, a candidate for the Democrats made  it 
official, former senator and former secretary of State,  Hillary Clinton, who`s widely seen as the frontrunner for the Democratic  Party.
All of the candidates will be campaigning heavily in  Iowa.  Its caucuses are usually the first major event in the nominations  process for U.S. 
presidential candidates.

Roll Call
AZUZ:  Time for the Roll Call.
Three requests from Friday`s transcript pages, CNNStudentNews.com.
Number one, the American International School of Johannesburg.  It`s in the city of Johannesburg in Eastern South Africa.
Two, Kahuku High & Intermediate School.  It`s in Kahuku, Hawaii.  The Red Raiders watching from the island of Oahu.
And in Moran, Kansas, The Sunflower State, we`ve got The Wildcats of Marmaton Valley Jr..-Sr.  High School.
When  you look into someone`s eyes and you see blue or green or brown, you`re  actually looking at the pigment in their irises.  The iris expands 
and contracts, controlling the amount of light that hits your pupils.   And it`s a unique identifier of who you are, kind of like your  fingerprint.
Researchers say new technology can help identify people by their eyes from up to 40 feet away.
(BEGIN VIDEOTAPE)
UNIDENTIFIED  MALE:  (voice-over):  You`ve seen eye scanners in movies like  "Charlie`s Angels," but even in real life, in order for eye scanners to 
work, they have to get up close and personal.

Long-Range Eye Scanner Technology
UNIDENTIFIED  MALE:   New technology is beginning to mimic another movie, "Minority  Report," where long-range devices are able to scan entire crowds 
from a distance, which has critics worried.
Every  person`s iris, that colored circle around the pupil of the eye, is  different.  That`s why police have started using them to build ID 
databases, like the FBI has done with fingerprints.
Carnegie  Mellon University`s College of Engineering is testing a new system that  it says can accurately read each iris`s unique signature from as far 
away as 12 meters.
Professor Mario Savvides says it could offer a safer way to ID dangerous criminals during police stops.
MARIOS  SAVVIDES:  That`s our long-range iris system at the back and what it`s  doing is, as I`m looking at the mirror right now, it`s actually 
finding my face, detecting my eyes, extracting features and then  matching them, running through the database to come up with the identity  of who I 
am.  It can really save the officer`s life by making sure that, you know, he`s far away and safe.
UNIDENTIFIED  MALE:   The American Civil Liberties Union fears police may use  long-range iris scanners to track people in large public crowds.  They 
say using scanners in that way might violate privacy rights.

Before We Go
AZUZ:   When springtime springs up in the U.S. Capitol, one plant that blooms  stands as a symbol of history and friendship.  The cherry blossom 
trees aren`t just at the National Mall to look pretty.  They were a  gift from Japan in 1912 that continue to bring color to the District of  Columbia 
every year.  Locals and tourists the world over can  see them near The Washington Monument, by The Tidal Basin, and in East  Potomac Park.  And 
following the doldrums of winter, they`re  sure to cherry you up with blossom some of the most flowerful leafings  that would never leaf you and 
your buds disappointed.
