John Glenn, First American to Orbit the Earth, Dies at 95; Syria Regime Forces Seize Most of Aleppo; Scientific Potential of Swarm Technology

Aired December 9, 2016 - 04:00:00   ET



First up today on CNN STUDENT NEWS: the passing of an historic American. John Herschel Glenn Jr. popularly known as John Glenn died yesterday at the

age of 95. A large part of his life was spent in the air. Glenn flew 149 combat missions in World War II and the Korean War.

He became a national hero, was one of America`s first astronauts. And in 1962, John Glenn became the first American to orbit the earth. He

reportedly wasn`t allowed on the moon mission, though, because President John F. Kennedy said he`d become too valuable as a national figure to go on

the flight.

On the ground, Glenn served in politics. He was U.S. Democratic senator representing Ohio for 24 years. He tried but failed early in his quest for

the presidency in 1984, but 14 years after that, Glenn returned to the sky at the age of 77, becoming the oldest person to fly into space.

Next in the Middle East. Aleppo used to be the most populated city in the nation of Syria. A large part of it has been abandoned and destroyed by

years of civil war. Rebels who`ve been fighting the Syrian government currently control part of Eastern Aleppo.

Syrian troops with the support of Russia`s military had been battling to get Aleppo back and they`ve made advances against the rebels in recent

weeks. Syria says its targeting terrorists there. The nation`s president says recapturing Aleppo would be a significant step toward bringing Syria`s

five-year-old civil war to an end.

But a British intelligence leader says that Syria and Russia are trying to eliminate opposition in Aleppo at any price, and that that`s created a,

quote, "human tragedy".

Thousands of civilians have been trapped in eastern Aleppo. There aren`t enough medical supplies to treat the wounded. Yesterday, Russia`s foreign

minister said Syria had suspended combat in Aleppo, so that civilians could get out. He called it the largest ever evacuation for residents of eastern



SUBTITLE: Why is Aleppo so important in Syria?

NICK PATON WALSH, CNN SENIOR INTERNATIONAL CORRESPONDENT: Aleppo is the commercial hub of Syria, symbolically unparalleled. This is which rebel

forces piled in summer 2012, taking large part of it, holding back to a better equipped Syrian military, showing that they could get popular

support in urban areas. It`s also where so much of the gross slaughter of this war occurred, where Syrian jets or helicopters just dropping the most

crude devices known as barrel bombs would repeatedly kill children, doctors, target hospitals. And if it finds itself again in Syrian

government hands, that is an enormous propaganda coup for the Syrian regime itself, after its Russia and Iranian support, it now has control on pretty

much of all the major population centers of Syria itself.

Secondly, the Syrian moderate forces themselves, they`re moving to that city in summer of 2012 showed they could be militarily effective. But if

they get kicked out, they don`t really have anywhere else at this point to go. If these moderate forces move in to Idlib, they could well be being

seen by the Americans particularly as too close to al Qaeda, a described terrorist group.

If east Aleppo falls, we simply don`t know how many civilians could get caught in this crossfire killed, injured (INAUDIBLE). Most importantly, if

it does fall as well, it marks a turning point in this civil war, one from which it can be pretty hard for those forces, for everyone used to call a

Syrian revolution to recover from.


AZUZ: Every year since 1927, U.S. publication "TIME" Magazine has named a Person of the Year, someone its editors say had the, quote, "greatest

influence, for better or worse on the events of the year.

Most U.S. presidents have been named since the tradition started. So as some other prominent world leaders, from the widely popular, to the highly

controversial, movers and shakers, doctors who helped Ebola victims, protesters and popes have all received the title. And this week, U.S.

President-elect Donald Trump was named "TIME`s" Person of the Year.

The magazine`s editor called the choice one of the more straightforward ones. She described Mr. Trump`s appeal as, quote, "part hope, part snarl."

She said he framed tomorrow`s political culture by demolishing yesterday`s, and said 2017 would bring in the chance to fulfill promises and defy

expectations like all newly elected leaders.


SUBTITLE: CNN STUDENT NEWS is changing, January 2017.



NICK GLASS, CNN CORRESPONDENT (voice-over): An extraordinary display by a flock of starlings, a so-called murmuration, a pulsating, palpitating

example of swarm or group behavior. It`s something we see in lots of specifies, fish, bees, ants. Each individual, both one and the many at the

same time.

Scientists have long been fascinated by it and now convinced we can learn from it for our own devices.

Dr. Sabine Hauert is a Swiss American scientist. She describes herself as a swarm engineer. Her aim, to imitate nature.

SABINE HAUERT, SWARM ENGINEER: If you look at birds and ants, they can do these beautiful, complex behaviors and I take inspiration from these to

engineer solutions for real world applications. So, we`re designing swarms of robots that could be used for outdoor applications and nano particles

that work in the trillions for cancer research.

GLASS: An arena in a robotic lab in Bristol in the west of England, how its research group are rallying their army of so-called killer bots.

Arranged at one end, a phalanx of them are ready for the order to move.

The thing I like about this is instantly, I recognize the sound of the swarm.

HAUERT (on camera): It definitely sounds like a swarm. It really bugged me.

GLASS: So, what`s the purpose of all this?

HAUERT: Robots are wonderful way to visualize swarm dynamics. And so, we use this as a proxy for the nano particles. Our nano particle robots are

released from the vessel here on the side of the arena and then they move randomly and they can go and they can stick to cancer cells, which we

projected on this arena. And once they`ve been in by the cell, they turn blue.

And so, we use this to show that although these particles are great at accumulating within these cancer cells, they`re for penetrating into this

robotic tissue. So, the group behavior is not great, even though the individual behavior is actually quite smart.

GLASS: Have you learned much from this already?

HAUERT: I learned tremendously just programming them and seeing how they behave.

GLASS (voice-over): Back in the arena, the killer bots form up again, ready to showcase that other swarm behaviors. The army is preparing to

show its colors.

The bots demonstrate decision making by changing from red to blue as a group, repetiting (ph) how swarms might choose a nesting site.

This time, it`s all about synchronization, mimicking how fireflies can coordinate their glow. And here, like ants, creating a trail from a so-

called source, transferring information back to their nests. The bots stopping once the link has been made.

And Hauert is hoping her research can find uses in the outside world -- a human-engineered robotic swarm to rival those created by nature.

HAUERT: I love to see these swarms of robots do things like monitor water sources, do things like explore a building that`s collapsed, do things like

potentially clean up an oil spill. We can`t engineer systems like this yet, so I think, why not look at nature for some of these solutions?


AZUZ: Before we go, you probably haven`t thought about asking for a penguin for Christmas? But this will probably change that. Santa Penguin

just slipped some fresh squid under the tree.

These little helpers are part of the fun in what`s known as Bird Park in Japan. It`s not unusual for the local penguin family to don soccer jerseys

when the World Cup is being played and Santa suits in December. The rest of the time, they just wear tuxedos.

Now, some might be a little flippant about this, to say something`s fishy about suiting up penguins. Maybe they`d call the idea north polarizing or

say Santa`s reindeer don`t include Ramon, Nestor, Raul or Lombardo. But this could be a penguining of a new tradition and what better time to start

than the most punderful time of the year.

I`m Carl Azuz. Fridays are awesome.
