CARL AZUZ, CNN STUDENT NEWS ANCHOR:  Hi.  I`m Carl Azuz.  
Less  than two weeks from Election Day in America.  The big question is who  will lead the country.  And we`re not just talking about the presidency.  
In the House of Representatives, lawmakers serve two-year  terms.  So, all 435 voting seats are up for election on November 8th.   In the Senate, 
lawmakers serve six-year terms.  And 34 Senate seats are up for election next month.
Here`s  what the balance of power looks like right now.  In the House,  Republicans have control with 246 seats.  Democrats have 186 seats.   There 
are three vacancies.
In the Senate, Republicans  have control with 54 seats.  Forty-six seats are considered Democratic.   There are two independents in the Senate, but they 
usually vote with the Democrats.  
No  one knows yet if control of either chamber will change hands in this  election.  But because Republicans have a smaller majority in the  Senate, 
analysts say Democrats have a better chance of gaining  control there and Republicans have a better chance of keeping control  in the House.  But 
again, this all comes to how Americans vote.
Why  this matters?  It`s easier for presidents to accomplish their goals  when Congress is controlled by their own party, the opposing party is  more 
likely to act as a check on the president`s power and can put more limits on what a president can do.
An  issue that politicians are discussing on the campaign trail is the  Affordable Care Act, also called Obamacare.  It`s a major reform of the 
U.S. healthcare system that President Obama signed in 2010.  It`s  considered is signature achievement and it contributed to a record  number 
of Americans having health insurance.  
But  Obamacare also had a number of problems.  One of them announced earlier  this week is a 25 percent increase in premiums, what people pay for an 
insurance policy.  It applies to one major Obamacare plan and it will  take effect next year.  The government says most of those who are  enrolled will 
receive subsidies, government money to help out  with the cost increases.  But that will make the program more expensive  for the federal government.  
Another issue, fewer insurance  companies plan to offer Obamacare next year.  That will leave people  with fewer choices for insurance.
Why is all this happening?   One big reason is that the people who`ve signed up have more health  problems than companies expected, making cost higher, 
and that not enough young healthy people have enrolled in Obamacare to balance that out.

SUBTITLE:  Battle for Mosul: The strategies.
FREDERIK  PLEITGEN, CNN SENIOR INTERNATIONAL CORRESPONDENT:  The battle to oust  ISIS from Mosul is what military experts would call asymmetric 
warfare.  That means adversaries with very different capabilities facing off against one another.
On  the one hand, you have around 50,000 Iraqi security forces and about as  many militias and Kurdish troops.  They`re also back by U.S.-led  artillery 
and advisers, and, of course, massive coalition air  power.  On the other hand, you have around 5,000 ISIS fighters, but they  are entrenched.  The 
coalition strategies to use superior manpower, firepower and technology to throw ISIS out of Mosul. 
For  its part, ISIS is trying to bog down the invading forces and use  guerilla tactics to slow them down.  For instance, the terror group has  dug 
a web of tunnels to escape airstrikes and to move around  the battlefield without being exposed to some of the heavy weapons the  Iraqi security 
forces are using.  They`re also employing  roadside bombs and a lot of suicide car bombers to not only slow the  advancing Iraqi forces down, but 
to try and demoralize them as well.
In  some cases, ISIS has managed to sneak back into towns already taken by  the Iraqi military, so holding and securing areas will be a big  priority.  
While ISIS has inferior technology and, of course,  much less manpower, combat in densely populated urban areas always  favors the defenders.
(END VIDEOTAPE)
AZUZ:  And that`s  why a few thousand ISIS terrorists are able to fight back at all against  the force of around 100,000 advancing international troops.  
The city of Mosul is expected to be ISIS`s last stand in the Middle  Eastern country of Iraq.  The terrorists still have a stronghold in  Syria, but a 
defeat in the Iraqi city would limit their territory and strength.
As  it`s retreated from the towns around Mosul, ISIS has used civilians as  human shields.  Its return to liberated areas to kill residents in  revenge, 
and it`s doing all it can to leave disaster burning in the wake of its retreat.

ARWA  DAMON, CNN SENIOR INTERNATIONAL CORRESPONDENT (voice-over):  It could  almost be waves rippling against a shoreline on another planet.  Neon 
streams catching the light.  But this hauntingly beautiful scenery is  toxic.  The yellow rock formations are raw sulfur, crumbling and melting  
under intense heat.  It may look volcanic but this is manmade.
(on  camera):  When ISIS withdrew from the sulfur factory, they placed  explosives inside what was a massive mountain of sulfur, sending toxic, 
poisonous fumes into the air.
(voice  over):  Hundreds of people in the area had to seek medical attention  for trouble breathing, burning eyes and choking.  Hospitals ran out of 
oxygen.  
(on  camera):  I have no idea of how the vast majority of these workers out  here are able to deal with the smell and the burning in one`s eyes  without 
having proper protection.  These people out here  actually don`t have gas masks on but they are working tirelessly to try  to bring this under 
control.
(voice over):  Across  this other-worldly landscape there are bulldozers, firefighters trying  to stifle the flames with loads of dirt.  This is a 
battlefield that has no rules or boundaries.
(on  camera):  And this is just one of the many ways that ISIS are trying to  use whatever it possibly can to try to not only impede the advance of  the 
security forces toward Mosul but also in doing so cause maximum damage and maximum impact on the civilian population.

AZUZ:   Now, continuing our two-part series on videogames.  Yesterday, we  looked at some possible mental and physical downsides of gaming.  Now  for a 
possible upside.  
Can videogames ability to stimulate certain areas of your brain be harnessed to give us better performing brains?
(BEGIN VIDEOTAPE)
DR.  SANJAY GUPTA, CNN CHIEF MEDICAL CORRESPONDENT (voice-over):  People who  play videogames actually see more than the rest of us.  They make  better 
and faster use of visual input, according to a recent Duke University study.  
What  if we could all benefit from this?  The goal is for doctors to one day  prescribe videogames like they would of medicine.  Think controllers 
instead of pills.  And this might not be too far off.
Meet  AJ.  He`s a research associate in Adam Gazzaley`s lab at UCSF.  You can  see he`s healthy as a horse, but Adam`s plan is to push AJ`s brain 
beyond its limits, to give him cognitive abilities that are almost super human.
AJ  SIMON, RESEARCH ASSOCIATE, UCSF COGNITIVE NEUROSCIENCE RESEARCH LAB:   Yes.  So, basically, I was going to be doing what we call digital  search.  
I was going to be looking for a target object and  ones about the detractors and I`m going to be using physical movements  to respond to the correct 
target.
GUPTA:  So, this is AJ.  He`s playing this game as you can see behind me.  He`s also all wired up.  That`s EEG monitoring.  
Take  a look at the game on the screen.  But I think more importantly is this  over here, this is actually AJ`s game as he`s playing the game.  You 
see the brain?  But you also see what`s happening inside the brain as a result of that EEG monitor.
(voice-over):   What makes the glass brain so revolutionary is not just the real time  3D visualization with a log time of just two-tenths of a second, 
but also something known as a feedback loop.  That`s the ability of the  game to use the data streaming out of AJ to optimize the game engine 
itself.
Too easy?  The game gets harder.  Too difficult, it lets up a bit.  
(on  camera):  So, back here for example is an area of the brain that`s  typically responsible for vision.  So, if someone`s not -- you`re not 
seeing much frequency or activity back there, the game may chance in response to that?
DR.  ADAM GAZZALEY, UNIVERSITY OF CALIFORNIA, SAN FRANCISCO:  Exactly.  And  the rewards will change in response to that, and when they do bring on  that 
activity or high level, they get rewarded.

AZUZ:  Dog, meet balloons.  Now, pop them to pieces.
This  is the handiwork of Twinkie the Jack Russell Terrier.  I can`t decide  if she really loves or really hates balloons, but she`s really good at 
popping `em.  Twinkie took home the 2016 Guinness World Record for a  dog- popping 100 balloons in the shortest time, 39.8 seconds.  And  Twinkies` mother Anastacia actually holds a previous world record for  popping 
balloons.  
So, it`s no ballooney to say the  family is just full of hot air.  The animal herself may be a little  ballooney.  Maybe the balloons just rub her 
the wrong way.  But when she embarks on her mission, she does a terrier.  She has a blast. 
And as any balloon will tell you, her bite is worst than her bark.
I`m Carl Azuz and these puns have left me deflated.
