:00:20. > :00:24.Hello, welcome to Newsround with Ricky Boleto and Leah Gooding.
:00:24. > :00:30.Coming up: We find out why scientists are so obsessed with the
:00:30. > :00:36.mysteries of Mars. And we meet the young basketballer
:00:36. > :00:40.with a keen eye on the Paralympics. First, if you're missing the buzz
:00:40. > :00:43.you felt during the Olympics just a few weeks ago, then fear not. The
:00:43. > :00:47.countdown to the Paralympics started today. A mammouth torch
:00:47. > :00:55.relay started in the four corners of the UK, but is it enough to get
:00:55. > :01:00.everyone excited about the Games? The countdown is on. Northern
:01:00. > :01:05.Ireland was the first up to the top of the mountain... There was a
:01:05. > :01:09.Paralympic flame lit here this morning. Wet windy and very high up,
:01:09. > :01:14.the last of four special torches catches light to mark the journey
:01:14. > :01:17.to the Paralympic Games. Carried to the top of the highest mountains in
:01:17. > :01:22.England, Wales, Scotland and Northern Ireland, these four
:01:22. > :01:26.torches will come together to light the flame in the opening ceremony
:01:26. > :01:32.in a week's time The past the Paralympics haven't always had the
:01:32. > :01:36.same attention as the Olympics, but tickets are almost all sold out. At
:01:36. > :01:40.Snowdon the man in charge told everyone they are in for a treat.
:01:40. > :01:44.think when people see Paralympic sport for the first time they'll be
:01:44. > :01:54.blown away by the quality of the sport and the spirits around them.
:01:54. > :01:56.
:01:56. > :02:02.The scouts don't need to be excited The scouting movement Kateers for
:02:02. > :02:06.all abilities and disabilities. what next? After the climbdown from
:02:06. > :02:10.the four mountains the torches head back to the UK's four capital
:02:10. > :02:16.cities for a big party. They will meet up again in the village of
:02:16. > :02:23.Stoke Mandeville why.? The Games were first held for disabled
:02:23. > :02:27.athletes 60 years ago. From there are a 24 hour relay with 600 people,
:02:27. > :02:33.they will carry it to the opening ceremony a week from today. Then
:02:33. > :02:39.the action really gets started. It is hoped the Games will inspire
:02:39. > :02:49.thousands of future Paralympians as well. Ten-year-old Archie has
:02:49. > :02:53.
:02:53. > :03:01.cerebral palsy, a condition hundreds of those taking part have.
:03:01. > :03:07.My name is Archie and I'm ten years old and I've got cerebral palsy.
:03:07. > :03:15.It affects my legs, because the signal from my brain can't properly
:03:15. > :03:21.get down to the legs. They are not as strong.
:03:21. > :03:27.Wheelchair basketball is very good, because it allows me to play with
:03:27. > :03:31.other people that feel the same way. And have the same bibl ti. We can
:03:31. > :03:37.just play together. -- disability. We can just play
:03:37. > :03:47.together. Kyle and Dion are two of my friends
:03:47. > :03:52.at basketball. My name is Dionne and I'm 13. My name is Kyle and I'm
:03:52. > :03:56.ten. He is a good player, but he sometimes attacks. He's got a
:03:56. > :04:02.brilliant right hand. Sometimes people think just because we are in
:04:02. > :04:08.wheelchairs we can't play sports, but if we are in while chairs we
:04:08. > :04:13.can still play Olympic sports. coach is called Steve. Steve
:04:13. > :04:23.inspires me, because he's on the England team. He brings a message
:04:23. > :04:26.that you can still do what you want to do.
:04:26. > :04:31.Tony Nicklinson, the man who lost a big court case about whether
:04:31. > :04:36.doctors could legally help to end his life has died today. We told
:04:36. > :04:39.you last week about Tony's case. He was paralysed from the neck down
:04:39. > :04:43.and could only communicate through a computer. He wanted doctors to be
:04:43. > :04:47.allowed to help him end his life, but the court ruled hena was
:04:47. > :04:54.illegal. He died at his home this morning.
:04:54. > :04:59.For the past few weeks all eyes have been on Mars. We've been
:04:59. > :05:04.following NASA's robot, Curiosity. Today it is taking its first steps.
:05:04. > :05:09.But what are we hoping the learn from the Rover and why are we so
:05:09. > :05:12.excited about a planet that's millions of miles away? Mars, it is
:05:12. > :05:16.a planet that's fascinated scientists for years. Why? Because
:05:17. > :05:21.of all the planets out there it's the most like Earth and the most
:05:21. > :05:26.likely to support life. Over the past 50 years there's been
:05:26. > :05:31.many missions to land on the Red Planet. It hasn't been an easy
:05:31. > :05:39.journey. Lots of these have failed. The first to successfully land and
:05:39. > :05:43.exlor the planet was Viking 1. Curiosity is the latest in a long
:05:43. > :05:48.line of Mars robots trying to work out if the plan keet have supported
:05:48. > :05:55.life. So after nearly -- planet could have supported life. So why
:05:55. > :06:00.are scientists so excited when we touched down on the planet? We've
:06:00. > :06:05.seen evidence of rivers that used to flow across the surface. The
:06:05. > :06:10.general aim of Martian exploration was to find out what happened when
:06:10. > :06:15.water flowed on Mars. It has taken a lot of money to send Curiosity to
:06:15. > :06:19.Mars, is it worth snifrpblts lit tell us about our place in the
:06:19. > :06:24.universe. Is it an incredibly unusual thing that we've got life
:06:24. > :06:29.on the Earth? If we wanted to live on Mars lit tell us what it would
:06:29. > :06:34.be like to live there, what we would need to do to make ourselves
:06:34. > :06:38.safe. So Curiosity is going further than any other Rover on the Red
:06:38. > :06:45.Planet, but until its two years of testing are complete, the mysteries
:06:45. > :06:52.of Mars will continue to fascinate. From core science in space to an
:06:52. > :06:58.amazing discovery on Earth. A teenager in America has shocked
:06:58. > :07:03.medical experts by coming up with a test to check for the world's
:07:03. > :07:09.diseases. This is Jack. He goes the High School and goes kayaking at
:07:09. > :07:13.the weekends, and coming up with cures for cancer. Most people play
:07:13. > :07:18.basketball, but I don't. I do Cancer Research. All that time
:07:18. > :07:24.research hag paid off and Jack has managed to create a pancreatic
:07:24. > :07:30.cancer test that's 168 times faster and much cheaper than the best test
:07:30. > :07:34.out there. All you have to do with the sensor is apply to blood sample
:07:34. > :07:39.and measure it. From that level that you get you can tell if the
:07:39. > :07:46.cancer is present. I got really interested in Cancer Research
:07:46. > :07:52.because a bunch of my family has been affected by pancreatic cancer.
:07:52. > :07:57.Jack recognises how lucky he is to have modern technology at his
:07:57. > :08:03.fingertips. Search engines like Google has allowed limb to become
:08:03. > :08:08.the young inventsor he is. Without that it what be near impossible.
:08:08. > :08:12.is at the early stages but Jack is hoping his test will eventually be
:08:12. > :08:16.used in every doctor's surgery in the world.
:08:16. > :08:24.Prince Harry has been making headlines today. He is in holiday
:08:24. > :08:32.in Las Vegas. This video shows him challenging America's gold medal
:08:32. > :08:36.winner in a race. Finally, can I remember the moment
:08:36. > :08:45.London was awarded the Olympic and ploich gay, but can you remember
:08:45. > :08:48.when Bristol won the bid to host the robot Games? Maybe not. There
