CARL AZUZ, CNN 10 ANCHOR: This is CNN 10. We are an objective explanation of news in 10 minutes and I`m Carl Azuz. Welcome to the show. A tornado and the effects of it lead things off for us today. We`re taking you to Dallas, Texas. That`s where daylight on Monday morning revealed the effects of the severe weather that struck on Sunday night. A cold front that`s sweeping east across the United States spawned the tornado. We don`t know yet how strong it was. Weather officials are still trying to figure that out but its effects were felt all over the Dallas-Fort Worth area. More than 100,000 households and businesses have lost electricity at one point though workers had restored it to half of them by midday Monday. 
Campus` were damaged which led to classes being cancelled at six schools on Monday and at a Dallas fire station, high winds blew off most of its roof. 
Dallas Mayor Eric Johnson said that considering the fact that the storm raked across a densely populated part of the city, it`s very fortunate that there were no lives lost and no serious injuries from the storm. He said it caused mostly property damage issues. Texas Governor Greg Abbott declared 16 counties disaster areas which will provide state resources to help people recover. Dallas is in tornado alley, a central part of the United States that sees a relatively high number of tornadoes. And even though they`re most common in the late spring and early summer, tornadoes can form at any time of year as this storm showed us.

UNIDENTIFIED FEMALE: When severe weather strikes, one of the most common questions we get, what`s the difference between a watch and a warning. 
Well just for comparison sake let`s take this stop light, green light, yellow light, red light. Sometimes the National Weather Service will issue a hazardous weather outlook, an advisory, treat this as a green light. Know that the possibility of rough weather is there but go about your day as you would just stay alert. But as conditions tend to ripen, we may see a tornado watch issued by the National Weather Service use this with more caution. 
This means conditions are favorable for tornado development and so you need to know what you should do in case a tornado strikes. That`s where the warning comes in. If the radar has indicated a tornado or someone has spotted a tornado in progress, that`s when the tornado warning is issued and you should get to your safe place immediately stop what you`re doing and seek shelter.

AZUZ: 10 Second Trivia. Tony Jannus, an American born in 1889 was best known for his accomplishments in what? Aviation, track and field, railroad construction, or yachting. Tony Jannus was an aviator, a barn stormer and the pilot of the world`s first commercial plane service. 
In 1914 that service was a 23 minute hop in a plane like this. It flew between St. Petersburg, Florida and Tampa, Florida. Commercial aviation continues to develop even today. The longest non-stop passenger flight in modern times looked like this. It was a 19 hour and 16 minutes haul between New York City and Sydney, Australia that was completed over the weekend. It covered 10,066 miles before touching down and for the 49 people onboard this was as much as an experiment as it was an achievement. Qantas, the biggest airline in Australia was working with medical researchers to see how passengers and pilots are effected by long haul flights like this. Depending on their findings, Qantas may offer more regular flights like it in the months ahead. 
Up next today thanks to what`s known as the internet of things, everything from lamps and toasters to washing machines and refrigerators can be connected to the internet and your smartphone and critics say a lot of this isn`t really useful or very smart. But this kind of technology is finding it`s way into wheelchairs that can climb stairs and canes that can give users advanced notice of obstacles and that`s an example of how everyday accessibility could dramatically change lives worldwide.

UNIDENTIFIED MALE: We need all stakeholders in our society to make the (inaudible) available to all. 
UNIDENTIFIED MALE: People with no disability they can not really imagine what that really means for people like me. 
UNIDENTIFIED MALE: There are 253 million visually impaired people in the world and these people have been still been using just a plain stick. 
UNIDENTIFIED FEMALE: Cities can be difficult places to navigate at the best of times, but to some with disabilities they can turn into gauntlets. 
With nearly 200 million people globally experiencing a severe disability, stairs, curbs (ph), train gaps (ph), even crosswalks can be impossible obstacles. But as devices grow smarter, cities are becoming more accessible. In fact, the assistant tech industry will be worth an estimated $30 billion by 2024. That`s up from $14 billion 2015. And when those disabilities are around 40 percent less likely to be employed, access of course has a huge impact on the economy as well.
UNIDENTIFIED MALE: It`s - - it`s very important to invest in our field because as a (inaudible) effect. If we deliver new technologies, it does not help just single persons. It helps a large group of users. 
UNIDENTIFIED FEMALE: Three of the most cutting edge examples are already changing lives. 
UNIDENTIFIED MALE: My accident was a collision with a motorcycle. In the first second, you - - you know what happens. 
UNIDENTIFIED MALE: I have (inaudible).
UNIDENTIFIED MALE: Roset (ph) he wrote us about a half a year ago when anyway that he would like to test the (inaudible)
UNIDENTIFIED MALE: Our goal is to develop a wheelchair that can climb stairs. 
UNIDENTIFIED MALE: (NOT TRANSLATED)
UNIDENTIFIED MALE: They called us to make a really - - a really cool robot at the start but then it switched over to - - to that (inaudible) because we saw there was such a huge need for - - for the people. 
UNIDENTIFIED FEMALE: The need is felt in cities across the world. In Paris, the European Union`s largest city, only nine out of more than 300 metro stations have full disabled access as of 2019. 
UNIDENTIFIED MALE: I think there`s a boom in the development of assistive technologies. Systems are getting more robust and smaller and smaller. 
UNIDENTIFIED FEMALE: These smaller systems are allowing assistive tech to become increasingly wearable. By 2025, they`ll be an estimated 25 billion connections between these things around the world. This will transform how devices operate within cities. 
UNIDENTIFIED MALE: Unfortunately I cannot name a single city as a perfectly disabled friendly city. That is why we`re trying to (inaudible) this (inaudible) for visually impaired people. When you walk with a smart cane developed for visually impaired people you can easily connect remote to your smartphone via the walks (ph) application and it`s so joyful - - you know you can poke with your cane and your cane is answering you. 
Navigation (inaudible).

UNIDENTIFIED FEMALE: Another of We Walks capabilities is obstacle detection imbedded in the handle is an ultrasonic sensor that maps the users surroundings. If an obstacle is detected the stick warns the user by vibration. 
UNIDENTIFIED FEMALE: (NOT TRANSLATED)
UNIDENTIFIED FEMALE: All of these technologies have had interests from other industries indicated that the good health of the assistive health sector can only be a good thing for society. 
UNIDENTIFIED MALE: There`s a lot of new movement and there will be a lot of new reasons. Robotic technology which attracts many people who do not have a relationship to any kind of person with a disability. It opens the minds of many people.

AZUZ: If you`ve ever wondered why someone would pay to be terrified by creepy clowns at a haunted house, at least this one comes with a car wash. 
It`s a haunted car wash in Brunswick, Ohio. For $20, you get a trick-or- treat bag, sheer terror and an air freshener to help afterward and even though the little kids may never be the same if you drive through a tunnel. 
At least the outside of your car will be clean. 
A little "clownin`" around when the water comes down, along with a wax you fear the attacks of the workers who are lurkers in make-up and makes bring you fears and tears and jeers as drivers pass. It`s where car care looks like "car scare" making you wince with the rinse, leave tread with your dread and never want to steer back through the ghostly scene thinking your scared car is better left unclean. I`m Carl Azuz for CNN.
