  • Welcome to CNN STUDENT NEWS on this Tuesday, February 24th.

  • It`s great to see you. My name is Carl Azuz.

  • Our commercial-free coverage starts on the Korean Peninsula today.

  • Large parts of it have been coated in yellow dust.

  • It`s not uncommon in this part of the world. The Koreas have a yellow dust season.

  • It typically runs from March to May and though it started early this time around,

  • this year`s yellow dust season isn`t expected to be as bad overall

  • as it has been in some other recent years.

  • Still, it`s nasty. The dust is measured in micrograms per cubic meter of air.

  • If there are more than 800 micrograms,

  • the Korea Meteorological Administration recommends that all outdoor events be canceled.

  • This week, a high of more than 1,000 micrograms

  • was recorded in one part of South Korea.

  • What is it made of and what can be done about it?

  • This is the worst yellow dust storm we`ve seen here in South Korea for more than five years.

  • A warning is in place, which means that the elderly,

  • weak and children are told not to go outside.

  • For everyone else, they`re advised to stay inside, but if they do have to go out,

  • they are advised to wear a putative mask and also preventive eyewear,

  • and if they`re inside, keep the windows shut.

  • Now, more people are wearing masks on the streets of Seoul,

  • although not as many as you`d think.

  • Seoul and the surrounding areas are the worst hit at this point.

  • Now this yellow dust blew in over the weekend

  • from Southern Mongolia and Northern China.

  • It`s a mixture of desert sand, topsoil and pollutants,

  • which is swept into the atmosphere and blown over other parts of the region.

  • Exposure to the particles in this are can be dangerous,

  • especially if you have existing health issues.

  • Today`s call of the roll takes us from North to Central America.

  • We`ll start in the north easternmost U.S. state,

  • in Old Orchard Beach, Maine, we heard from The Seagulls.

  • They`re soaring over Loranger Middle School.

  • In The Garden State of New Jersey, The Panthers are stalking CNN STUDENT NEWS.

  • They`re at Point Pleasant Borough High School in Point Pleasant.

  • And in the capital of Costa Rica, which is San Jose,

  • hello to our viewers at Sojourn Academy.

  • It`s great to see you this Tuesday.

  • Super bugs might not sound particularly serious,

  • but these are bacteria that have become immune or resistant to antibiotics.

  • They`re hard to get rid of and they can be deadly.

  • One patient at a North Carolina hospital has died after catching a super bug called CRE.

  • It`s not clear yet if the bacteria itself caused the death.

  • But CRE was linked to two recent deaths in Los Angeles,

  • so some scientists are raising the alarm about super bugs.

  • In the race to stay one step ahead of infectious diseases, we seem to be losing.

  • Super bugs carrying drug-resistant forms of disease

  • like malaria and tuberculosis are growing fast.

  • And today, the threat to the human race from these deadly new diseases

  • is more certain than that from climate change.

  • That`s according to a study commissioned by the British government.

  • Today, drug-resistant diseases claim the lives of around 700,000 people each year

  • Now, that`s expected to leap to 10 million by 2050.

  • Compare that with today`s deaths from cancer, 8.2 million each year.

  • Now the study goes further to talk about the economic impact,

  • predicting global costs will spiral upwards to $100 trillion, a staggering figure,

  • especially when considered alongside annual world GDP today, around $70 trillion.

  • According to the economist, Jim O`Neill, who led the study,

  • even that is an optimistic scenario.

  • We`ve left out a number of things.

  • It doesn`t look at the cost of increased health care.

  • And most importantly,

  • it doesn`t I called stuff that has become so normal for our generation,

  • or at least in the developed world, like hip operations,

  • knee operations, chemotherapy, etc. Etc. All of which could become impossible.

  • And back of the envelope stuff we`ve done on that could be double that number.

  • So it`s -- it`s really big.

  • The main culprit is over prescribing of antibiotics.

  • My generation thinks of antibiotics as something that will solve everything when you take one.

  • And it`s not true. And what we`ve -- we`ve got to reeducate ourselves

  • and help the next generation think differently.

  • It is, not surprisingly, the world`s poorest nations that are most at risk.

  • Nine of the estimated 10 million deaths will be in Africa and Asia.

  • The aim of the study is to sound the alarm and galvanize global action.

  • You`re not going to be able to solve this by just focusing only in the U.K.

  • or in Europe, or, indeed, just in the developed world, it`s going to affect everybody.

  • So it`s something that there has to be a collective agreement on.

  • Rosie Tomkins, CNN, London.

  • Time for the Shoutout.

  • Which American inventor was known as the the "Wizard of Menlo Park?"

  • If you think you know it, shout it out.

  • Was it, A, Alexander Graham Bell, B, Thomas Edison,

  • C Henry Ford, or D, Madam C.J. Walker? You`ve got three seconds. Go.

  • Thomas Alva Edison was called the "Wizard of Menlo Park"

  • for the work he did in Menlo Park, New Jersey.

  • That`s your answer and that`s your Shoutout.

  • Edison made some of his most famous inventions In Menlo Park.

  • A device that made it easier to hear on the telephone,

  • the phonograph, devices for electric light and generating electricity.

  • Of course, those inventions have been refined and improved on since the 1870s,

  • and though some people are concerned about a possible loss of their privacy

  • when it comes to things like smart grids,

  • a model in Germany could be a sign of things to come.

  • In 1882, on Pearl Street in New York City,

  • Thomas Edison opened the world`s first commercial electric grid,

  • lighting up local homes and businesses with cables connected to his power station.

  • Today, while the cars, the fashion and the skyline may all have changed.

  • The way we power our cities substantially hasn`t.

  • What if we could bring the whole grid up to date?

  • Let`s visit Mannheim in Germany.

  • Every house in Mannheim is connected to a smart energy network,

  • making the most of renewable energy.

  • Now this is not just a set of smart homes, it`s a smart city.

  • What I think is that the power grid can become a brain for the city

  • by all that information that are generated in the grid.

  • We first thought about, OK, how should the future smart grid look like?

  • So we started with a very small number of households in the first project phase.

  • It was 20 households. Then we grow that to 200 households in the next year.

  • And then the year after, we went to the large scale

  • project with 1,000 private customers connected to our grid.

  • At the heart of the network lies a butler,

  • not like Mr. Carson from "Downton Abbey,"

  • but the energy butler, a small box that monitors

  • how much power you`re using when boiling the kettle

  • or watching your favorite movie, for instance.

  • All this information is then fed back

  • by a series of smart meters to a central system

  • that learns how much power is being used where and when.

  • We were using (INAUDIBLE) and power line communication technology

  • in order to transfer data from A to B.

  • Over the power grid itself,

  • we can send information back from the meters,

  • from measurement devices about power quality, about the current status of the grid.

  • The network is designed to use as much renewable energy as possible

  • and as well as being good for the environment,

  • it`s designed to help your bank account, too.

  • The availability of renewable energy always leads to a lower price of electricity.

  • And we use that mechanism and forwarded it to the private customers.

  • What`s happening in Mannheim is but an experiment.

  • And it`s a vision for the future,

  • because what`s happening in Germany could very quickly be adopted

  • on a much larger scale elsewhere.

  • It would work everywhere because the power grids worldwide are operated

  • more or less the same way.

  • We developed this architecture that it can be implemented everywhere.

  • With a smart grid in place, the future of our cities may just be a little brighter.

  • Red pandas, also called bear cats, are no strangers to snow.

  • In nature, the endangered mammals can be found in the Himalayan Mountains.

  • We found this one at the Cincinnati Zoo in Ohio.

  • It doesn`t look like it`s uncomfortable in the cold.

  • In fact, it looks like it`s having the time of its life.

  • Red pandas are about the size of house cats, and apparently every bit as playful.

  • The two frolicking at the Cincinnati Zoo are named Rover and Lynn.

  • Even if you`re sick of winter and wanted to panda snow, you couldn`t panda bear.

  • He could certainly bear the cold without seeing red.

  • A native of the mountains, you didn`t see him a laying around.

  • I`m Carl Azuz for CNN STUDENT NEWS.
