CARL AZUZ, CNN STUDENT NEWS ANCHOR:  Hey, I`m Carl Azuz for CNN STUDENT NEWS.  It`s good to see you this January 26th.
First  up, except for Canada and Continental Chile, the danger is Zika virus.   It`s expected to spread to every country in the Americas.  That`s 
according to the World Health Organization.  And it`s because the  mosquito that transmits the virus is found throughout the Western  Hemisphere.
Zika was first discovered in Central Africa in the  1940s.  Eighty percent of people who catch it have no symptoms.  Others  might get a fever or a 
rash for a few days.  But Zika has been  linked to an increase in babies born with microcephaly, which can cause  abnormally small heads and severe 
delays in children`s development.  There`s no treatment and no cure.
So,  the U.S. Centers for Disease Control is urging pregnant women to avoid  many countries in Central and South America and the Caribbean.
There  are also concerns about this year`s Summer Olympics in Brazil, though,  official say there will be fewer mosquitoes around when the games 
are played in August, a winter month in Brazil.
The  mayor of Washington, D.C., says it will be days before snow is removed  from some parts of the nation`s capital.  Some schools in Maryland, 
Pennsylvania, New Jersey and New York are still close after a major weekend snowstorm.
Across the Pacific, millions are dealing with similar weather.  A cold shock spreading record low temperatures across East Asia.

MATT  RIVERS, CNN CORRESPONDENT (v:  Frost in a place known for its flowers.   Hong Kong saw record low temperatures over the last few days,  accumulating 
ice, trapping hikers on one of the city`s famous  mountain trails.  Dozens were treated for hypothermia in the coldest  weather the city has 
experienced in decades.  And Hong Kong wasn`t alone.
Across  Asia, we`ve seen bitter winter weather.  No where it hit harder than in  Taiwan.  State media there reported at least 85 people, most of them 
elderly, died from hypothermia or cardiac conditions likely caused by  the frigid air.  It`s an island where most of the homes don`t have  central 
heating.  It`s people simply not used to the cold.  
And  the winter weather caused travel nightmares across the region.  Take  the South Korean island of Jeju.  It`s a popular destination for  tourists, 
many of whom were camped out in the airport over the weekend.  Over 1,000 flights were cancelled, affecting 90,000 travelers.
And  in southern China, a similar story.  Train tracks were shutdown and  highways were closed due to snowy conditions in the eastern and southern  
portions of the country, areas known more for good food and  balmy weather than for snow.  Hundreds of flights were cancelled too on  the first weekend 
of the incredibly busy Chinese New Year travel season.
This  weekend was a day of weather firsts for many in East Asia, just ask  these school kids, gingerly stepping through snow of Japanese island of 
Amami Oshima.  No one who lives on the island has ever seen a snow  there before because it`s the first time it`s happened in 115 years.

AZUZ:  This "Roll Call" like every roll call is brought to you by yesterday`s transcript page at CNNStudentNews.com.
Rock Valley Middle School is in Iowa.  It`s the home of the Rockets, who totally rocket in Rock Valley.
To the Southeast, Pine View Middle School is in Florida.  It`s the home of the Panthers, the big cats of Landau Lakes.
And on the island of Taiwan, we`re making a stop in Taipei today to say hello to the students of Grace Christian Academy.
We`re  kicking off a two-part series today on the past and potential future of  transportation, planes, trains and automobiles.  If you think that cars  
have come a long way since the Gilded Age, and rockets have  come a long way from the Space Age, you might be amazed at how little  has changed and how 
much could change in the decades ahead.

REPORTER:   We first got seriously moving with the help of steam power in 1802.  A  British mining engineer Richard Trevithick built the first large 
scale steam powered locomotive.
In  1879, a German engineer Carl Benz developed the first internal  combustion engine, burning fuel like oil and petrol to power pistons.   And 
so, the car was born.
Only five years later, in  1884, the first electric car born (ph) into life thanks to a British  inventor Thomas Parker.  His vehicle was battery 
powered and most tested on the streets of London.  
A  man famously took flight in 1903 in North Carolina in America, with the  Wright Brothers Orville and Wilbur and their propeller plane the Wright  
Flyer 1.  The flight was just 12 seconds, barely seven meters off the ground, but immutably historic.
1940  saw the invention of a jet engine by a British engineer Frank Whittle,  thus used in fighter planes towards the end of the Second World War, and  in 
commercial passenger liners from 1949, with the British de Havilland Comet.
Fast  forward 50 years or so, there`s now a greater sense of urgency among  scientists, to find cheaper, more energy efficient quicker ways of  getting 
us around.
Richard Varvill is an engineer.  He  spent his entire career designing rocket and jet engines.  Varvill and  his colleagues are taking a unique 
approach, a hybrid rocket and jet engine, the SABRE.
RICHARD  VARVILL, ENGINEER:  The fundamental problem is that a state of the art  rocket engine, its performance in terms of its fuel consumption is too 
high.  So, the sort of central principle behind the engine that we`re  working on is to basically synthesize a rocket engine with an  air-breathing 
engine like a jet engine.  For this to be  worthwhile, the air-breathing has to operate up to speeds maybe twice as  high as a sort of conventional jet 
engine can range. 
Sort  of the holy grail on spaceflight is being together a machine can fly  into space and come back again and do it cheaply and safely and  reliably, 
and in fact, there`s been no real progress in terms  of the way in which we get into space, since the very start of the space  age.  So, the actual 
technology we`re working on is designed to solve that problem.  
REPORTER:   Although the SABRE is being designed to take us into orbit, it may  usher in a new era of travel back on earth, the Hypersonic Age.  The 
LAPCAT plane as they call it promises staggering speeds of more than  3,000 miles an hour, or put another way, flying from London to Sydney in  four 
hours.
VARVILL:  What we have to do now is build  a natural running engine.  And that we`re planning to do by the end of  the decade.  And that will then 
hopefully sort of destroy all the other naysayers that think this can`t be done.

AZUZ:   So, yesterday was a holiday, but we`re not going to judge if you  didn`t realize it was Bubble Wrap Appreciation Day.  This happens every 
year in the last Monday in January.  It`s all about the plastic package  cushion that both protects whatever is being shipped and happens to be 
really to pop.
CNN visited the factory and found that bubble wrap is only part of its story.
(BEGIN VIDEOTAPE)
VANESSA  YURKEVICH, CNN REPORTER (voice-over):  Inside Sealed Air`s headquarters  in Saddle Brook, New Jersey, they may get by the truckload 
every hour.  But there`s something new happening.  In their lab, they`re  creating boxes that self inflate, bubbles that inflate on sight and 
packaging that takes the shape of a product, once it`s cracked much like a hand warmer.
UNIDENTIFIED MALE:  This is not made out of plastic.  It`s made out of mushrooms.
YURKEVICH (on camera):  Mushrooms that I can eat?  
UNIDENTIFIED MALE:  Mushrooms that you can eat.  Oh, it doesn`t smell.
YURKEVICH:  It doesn`t smell like mushroom.  Does it take like mushroom?
UNIDENTIFIED MALE:  No.
(LAUGHTER)
YURKEVICH (voice-over):  But bubble wraps started it all.  And like other brilliant inventions, it was made by accident.  
The  story begins in 1957 when these guys were trying to make wall paper.   It didn`t quite stick, but from that failure, bubble wrap is born.
(on camera):  What is the secret to making bubble wrap?
ED ACKERSHOEK, SR. ENGINEER, SEALED AIR:  I`m not going to say that.
(LAUGHTER)
ACKERSHOEK:  Come on down.
This would be one of the resins (ph) that we`re using on the product.  
YURKEVICH:  And this is essentially plastic?
ACKERSHOEK:  This is plastic.
YURKEVICH:  And then it gets sucked up into these huge tubes --  
ACKERSHOEK:  From here, we will suck it up into anyone of the three lines.
YURKEVICH (voice-over):  To form the bubbles, the plastic is melted down at 500 degrees into a consistency like molasses.  
ACKERSHOEK:  Once we vacuum form the bubble, then we include another layer of material to seal the air inside the bubble.
YURKEVICH:   It`s cut down to size by a million dollar machine, and there are over  100 different kinds of bubble wrap, customized for almost every 
major shipping company in the world.
Bubble wrap is actually only 3 percent of the company`s revenue.  Their newer, innovative packaging isn`t so easy to pop.
(on camera):  So, this is kind of a thing of the past and this is a thing of the present and future?
ACKERSHOEK:  That`s exactly right.
YURKEVICH:  No bubble wrap.
(LAUGHTER)

AZUZ:   So, if you wrap a bobble head in bubble wrap, does that make it a  bubble head?  If you pop bubble wrap with your teeth, does that make it 
bubble gum?  If you drop it, do you babble it or bubble (ph) it?  If  you skip it, are you thinking outside the bubble?  And if you do nothing  but 
pop, are you bubbling with a bubble or bubbling with a bobble, or bubbling with a bubble (ph)?  
I hate to burst your bubble y`all but that wraps things up for us today.  Stop by tomorrow.  We`ll keep the puns popping.
