  • Great to see you this Thursday and thank you for logging on

  • or tuning for 10 minutes of current events.

  • I'm Carl Azuz. First up, an international increase in security.

  • There are more visible police in airports across the U.S., train stations and tunnels,

  • places where masses of people gather and travel.

  • They're all in a state of heightened alert.

  • In several cities around the world,

  • even where officials say there are no specific threats at this time,

  • more security forces are on guard,

  • following Wednesday's terrorist attacks in the Belgium capital of Brussels.

  • Thirty- one people were killed and 270 wounded

  • when an airport and train station were targeted.

  • ISIS said it was responsible.

  • Belgian police say there were four attackers in all.

  • Two of them were brothers who died.

  • One of the suicide bombers hasn't been identified yet

  • and another suspected terrorist is on the run

  • after placing a bomb at the Brussels airport that did not go off.

  • Police raids continue throughout Brussels, which is under its highest terrorist threat warning.

  • A soft target is a place where people are gathered, such as an airport, train terminal,

  • or even a stadium where before they can get through screening,

  • they are essentially unprotected.

  • They are prime targets for terrorists.

  • From what we've seen from al Qaeda and from ISIS is that they train to attack soft targets.

  • They know that these are places where people are going to be gathering

  • and where they're going to be unprotected.

  • We saw that in the Paris attacks where a couple of the suicide bombings

  • happen outside of the Stade de France.

  • In Brussels, we saw the airport and the metro station.

  • One of the first things that authorities worry about after an event like Brussels

  • is the possibility of copycat attacks,

  • people who might just be thinking of doing something and they get inspired.

  • So, that's one of the reasons why you see an increase presence of police

  • in places like Times Square, in places like Penn Station.

  • You can only keep that increased presence for a few days.

  • It's intended to make sure that you show an increased vigilance.

  • But then the harder work begins behind the scenes.

  • Wherever you put the security cordon, there's still going to be a line.

  • And a line is always vulnerable.

  • So, the U.S. has a very robust system whereby they do sting operations

  • to try to find these people who are online, who are talking about carrying out an attack.

  • It's a very controversial tactic, but so far,

  • it has prevented a lot of attacks in the United States.

  • In other countries they're starting to copy that formula to try to do the same thing.

  • Next story today, a black box warning.

  • It's the strongest one that the U.S. government gives on the labels of dangerous medications.

  • And the Food and Drug Administration just decided to include a black box

  • on commonly prescribed opioid painkillers.

  • The warning itself mentions the risk of abuse, addiction, overdose, and death.

  • It already exists on extended release painkillers.

  • Now, it will appear on more commonly prescribed, immediate release opioids as well.

  • It's meant to further educate doctors as they prescribe these medications,

  • and it's part of an effort to fight an increase in overdose deaths.

  • Officials say prescription narcotics now

  • kill more Americans every year than car accidents.

  • Some critics say the FDA's move is too little, too late.

  • That abuse of these drugs has already killed too many people.

  • Others say the new warning won't make much difference,

  • or that it could make it harder for people with chronic pain

  • to get the medications that help them manage it.

  • Before we can explore your brain on opiates,

  • we need to understand a few things.

  • An opiate is chemical derived from opium and it's the key ingredient in heroin.

  • Those narcotics in your medicine cabinet, codeine, oxycodone, hydrocodone,

  • they're opiate-like, but they are man-made and more commonly referred to as opioids.

  • So, how do these chemicals affect the brain?

  • One big way is by exerting powerful pain relief to the rest of the body.

  • Chemicals flood the system, latch on to millions of opiate receptors peppered throughout the body.

  • Think of opiates and the receptors like puzzle pieces.

  • When they bind together, pain signals are dulled, or they go away all together.

  • If the brain already has opiate receptors,

  • doesn't that mean it can naturally provide pain relief?

  • That's right. Feel good chemicals like endorphins

  • are natural opiates that dull pain and also give you a rush.

  • The problem with manmade opiates that mimic endorphins,

  • take too many and they can overwhelm the system, give you too much of a rush.

  • That can lead to dependence or abuse.

  • Addiction becomes an ever bigger problem,

  • because opiates also slowdown breathing and heart rate.

  • Mix them with other things that slow down your body

  • and everything could grind to a halt.

  • In fact, every 19 minutes, someone dies of an accidental prescription drug overdose.

  • Most of the time, it involves an opiate.

  • It's now more common than dying in a car crash.

  • If you want to avoid that fate, don't take more than you're prescribed.

  • Don't use other people's prescriptions. Never mix opiates with alcohol.

  • And maybe try other ways of alleviating your pain,

  • like over the counter pain relievers and good old fashion exercise.

  • One of the ways our show is used worldwide is to help students and adults practice their English

  • and we welcome everyone who does.

  • That includes Lycee Francoise.

  • It's in the community of Tournefeuille, in Southwest France.

  • Stateside, we're stopping by Susan B. Anthony Middle School today.

  • It's in one of Minnesota's Twin Cities. The Panthers are prowling around Minneapolis.

  • And we've got some more big cats watching.

  • The Cougars of Albuquerque, New Mexico, they're at Kennedy Middle School.

  • Up next, what's likely the largest flying aircraft on the planet.

  • Now, when we say that, you might think this, the Hughes H-4, aka, the Spruce Goose.

  • It has the longest wingspan.

  • But well-before its maiden and only flight in 1947, people flew on airships and that was risky.

  • The lighter than air hydrogen that gave them lift was highly flammable.

  • And after the R101 airship disaster in 1930 killed 48 people,

  • and the Hindenburg explosion in 1937 killed 36,

  • safety concerns have haunted these aircraft.

  • Today, though, helium has replaced hydrogen

  • and carbon fiber,Kevlar and Mylar have replaced cotton fabric.

  • This ship doesn't have the speed or the cargo capacity of say a Boeing 737,

  • but it can land where passenger jets wouldn't dare to try

  • and it could signal the rebirth of the airship.

  • We see Airlander as the future of air travel.

  • It's going to be cheaper, it's going to be greener,

  • we're going to be able to go from places that you can't go from now.

  • It's going to be a whole revolution in how we knew air transport.

  • World's Biggest Aircraft Unveiled

  • Airlander 10 (ph) is a hybrid vehicle, a mixture of a heat lift vehicle

  • with helium lift and vectored trust and ergonomic lift.

  • So, a new type of aircraft. It's a 10-ton lift vehicle and it's 300 feet long.

  • British firm Hybrid Air Vehicles spent nine years refining its technology

  • and has now completed the full assembly of Airlander 10,

  • which was floated inside one of the world's biggest aircraft hangars.

  • It's really quite a special machine to fly.

  • The views you see from the flight deck was excellent because of large, large windows.

  • It's very special because it really has an agility and ability

  • that nothing else has at the moment,

  • plus 12 times capacity of fuel which allows them to fly up to 5 days,

  • doesn't get any prepared surface for operating

  • We can land it almost any flight surface, whether it's water, grass, sand.

  • It can land at no infrastructure at all.

  • The vessel was originally designed for surveillance by the U.S. Army,

  • and the military prototype flew from the first time in 2012.

  • But budget cuts doomed the project in 2013.

  • Hybrid air vehicles now hope to use the new Airlander for a mix of purposes.

  • Whether it's being in Safari, whether it's sightseeing in places,

  • whether it's doing surveillance work,

  • a whole range of uses being demonstrated with this vehicle.

  • The firm hopes the Airlander will fly outside the hangar this summer.

  • OK. The headline sounds awesome.

  • Massive exploding star caught on camera.

  • The video looks awesomer.

  • A massive exploding star caught on camera.

  • But this, sorry to say, is just a cartoon animation.

  • The actual footage, maybe not as awesome. Yes, there you go.

  • An optical wavelength measurement provided by the Kepler telescope

  • that indicates what scientists say is the explosive death of a star hundreds of millions of light years away

  • that began with the 20- minute shock breakout

  • and progressively got brighter over a period of two weeks.

  • But if you want to talk about a massive supernova going out in a blaze of glory,

  • the cartoon is a better place to start.

  • Starring down startling discoveries is an e-star-nation.

  • A star-entific de-star-nation that's always on star-get.

  • Will scientists one day capture actual video like that?

  • Never say nova.I'm Starl Azuz and CNN star-dent news stars again tomorrow.

Great to see you this Thursday and thank you for logging on
