CARL AZUZ, CNN 10 ANCHOR:  There was some breaking news Thursday night as we produced this edition of CNN 10.
The  Champs-Elysees, a popular boulevard in Paris, France, was closed.  The  French government says an attacker with an automatic weapon deliberately  
targeted police officers.  Initially report said that one  police was killed and two were injured and that the attacker was also  killed when police 
returned fire.  
The Champs-Elysees  is one of the most famous streets in the world.  It`s lined with  restaurants, boutiques, shops and cafes.  It`s just a few blocks 
from the country`s presidential palace.  And the nation is already on  heightened alert because general elections begin on Sunday.
French intelligence officials are looking at this as a possible terrorist attack, but the investigation has just started.
Moving  to the Korean Peninsula, where officials are examining satellite images  of a potential volleyball game.  It`s a popular sport in the 
communist nation of North Korea, and according to 38 North, a service  that monitors the secretive country, these pictures appear to show  volleyball 
games taking place at a North Korean nuclear test  site.  People who work there might be having some down time.  They might  be standing by for orders 
from their nation`s leader, Kim  Jong-un.  The U.S. military says North Korea is able to carry out a  nuclear weapons test at anytime and it`s not 
likely to announce it first.
Its  neighbor to the north, China, is reportedly making preparations for  trouble in North Korea.  A U.S. defense official says Chinese bombers  were 
put on high alert this week and that an extraordinary number of Chinese warplanes are being prepped for possible service.  
Why is China concerned?  
For  one thing, it`s North Korea`s closest ally.  North Korea depends on  China for 80 percent of its international trade.  For another, if war 
breaks out on the Korean Peninsula and the North Korean government  collapses, refugees may try to flood over the country`s border with  China.  
It also doesn`t like the possibility of a reunified Korea under a South Korean government.  South Korea is an ally of the U.S.

PAULA  HANCOCKS, CNN INTERNATIONAL CORRESPONDENT:  This is Max Thunder, a  massive air exercise between the U.S. and South Korea.  There is about  80 
aircraft involved in this, more than 1,500 personnel.  
Now,  we`re told it`s routine:  It is annual.  The lieutenant colonel in  charge of it said that it has been planned for months, and they don`t  have 
a specific enemy in mind when they`re carrying out this exercise.  
But,  of course, with what is happening on the Korean Peninsula, and that  right now, means that this is very much in the spotlight.  We know that 
North Korea has blamed the United States for pushing to almost the  brink of war.  And there is rhetoric on both sides being very strong at  this point.
But from this point of view, the people who are  involved in this particular exercise say that it`s just important for  them to be able to know how to 
work with each other in case of  a war.  We`re being told that this is as close a simulation as you can  get to a possible war situation.  
Now, of course, North Korea  does not like these military options.  They see this as a practice for  invading North Korea.  The U.S., though, says that 
they are  defensive.  China doesn`t like them either.  They have even suggested to  the U.S. and South Korea that if they actually halt these 
drills, then North Korea may suspend their nuclear and missile program.  
It`s not a new suggestion, and it`s not a suggestion that the United States accepts.

AZUZ (voice-over):  Ten-second trivia:
Which of these words comes from a Latin term meaning "gate"?
Patio, portal, plaza or probe?
Portal can be traced back to the Latin word "porta", which means gate or entrance.
(END VIDEO CLIP)
AZUZ:   A network of portals set up in shipping containers is giving people  the chance to meet face to face with others, from Africa, Asia, Europe,  the 
Middle East, South America, without leaving their own  cities.  The company that sets this up is Shared Studios.  Its portals  are founded by public or 
private organizations.  It depends on  who wants to host a portal.  What`s needed is access to land,  electricity, internet access, people to run the 
portals, and their use is free to the public.  The connections are immersive, interactive, and international.
(BEGIN VIDEOTAPE)
UNIDENTIFIED MALE:  I want to talk to someone who has a really different life experience for myself.
STEPHANIE  ELAM, CNN CORRESPONDENT (voice-over):  Behind its golden exterior, this  shipping container in the middle of downtown Los Angeles is 
a portal to the world.
UNIDENTIFIED MALE:  I am Ravi (ph).  This is Ahmed.  We all are from Iraq.
UNIDENTIFIED MALE:  Tell me a little bit about what life in Irbil is like.
UNIDENTIFIED MALE:  You know, we are refugees.
ELAM:   Equipped with immersive audiovisual technology, the portal allows for  causal interaction between people in different parts of the globe, 
without the restrictions of a computer screen.  
UNIDENTIFIED  MALE:  When you enter it, you feel like you`re on the same room, as  someone in identical shipping containers somewhere else in earth.
ELAM:  Amar Bakshi launched the first portal in 2014 between New York and Iran.
UNIDENTIFIED  MALE:  We`re trying to create a global public space where people from  all walks of life and all types of different institutions can 
come together and everything from a conversation with a stranger to play  to collaboration.  The strength of the network is its diversity.
ELAM:   There`s about two dozen portals permanently located around the world,  from Afghanistan to Mexico.  Every location communicates at some 
point with every other portal and all are welcomed.
UNIDENTIFIED  MALE:  Each of our portals is staffed by a local curator.  They  maneuver the politics and the messaging necessary to operate in all 
these sites.
ELAM:   It is the job of the curators to engage their communities and invite  passer-bys to enter the portal for a chat.  They also schedule  reoccurring 
events.
UNIDENTIFIED MALE:  We hear so  many stories of people having the ability to be anonymous and to then  express cruelty to others.  And this is the 
antithesis of that.
ELAM (on camera):  What do people think of this portal there in Iraq?
UNIDENTIFIED MALE:  You can get new information about the cultures, about the life in other countries outside of Iraq.
ELAM:  Ravi and Mustafa, my new friend, ma salama!
CROWD:  Ma salama!
ELAM:  Stephanie Elam, CNN, Los Angeles.

AZUZ:  One rule of thumb for losing weight is the 80/20 rule, that 80 percent of it is determined, 20 percent is exercise.
In our continuing health series with Dr. Sanjay Gupta, we`re looking at diet suggestions for living a longer life.
(BEGIN VIDEOTAPE)
DR.  SANJAY GUPTA, CNN CHIEF MEDICAL CORRESPONDENT:  People always talk  about wanting to get healthy and talking about diet and exercise.   That`s 
exactly what you should be talking about.
But here`s the little secret: diet is far more important than exercise when it comes to actually accomplishing those things.
If  you want to look at what these diets that doctors like have in common,  there are really three basic things you need to look for.  
They  got to have a lot more vegetables.  They are going to cut way back on  sugars.  And they are also going to be cut back on grains, particularly 
refined grains.  
There  are people who will say look, if you want to completely rid your risk  of heart disease, perhaps you shouldn`t eat meat at all.  Just don`t eat  
any red meat in particular.  And those are people who say  look, that`s going to hard for me to do, by cutting back and when you do  eat it, making 
sure it`s no bigger than the size of your palm. 
I  love this thing that they do in Japan.  And the phrase is called hara  hachi bu.  What it basically means is that you push the plate away when  you 
are about 80 percent full.  The point is, you never stuff yourself.  
Here`s  a little tidbit when it comes to diet: it can improve your health and  it can increase your longevity, helping you live to 100.

large by the Canadian ice service.  The means it`s higher  than 150 feet and longer than 400 feet.  Iceberg Alley is iceberg season  runs from spring 
through late summer.  Ocean currents carry the berg south before the September.  
A CNN meteorologist says it`s unusual to see one this big this close to shore.
And  to think the season is just berginning.  Who knows what ice will flow  beflow the season is flowver.  Those who are enthuseicestic about this  are

cool as ice.
