0:00:53 > 0:00:58I accept your nomination for President of the United States.
0:00:58 > 0:01:00CHEERING
0:01:00 > 0:01:03Yes, the world is watching what we do.
0:01:03 > 0:01:08Yes, America's destiny is ours to choose.
0:01:08 > 0:01:14So let's be stronger together, my fellow Americans.

0:01:20 > 0:01:23We are exactly one week away from the official start
0:01:23 > 0:01:25of the Rio Olympic Games in Brazil.
0:01:25 > 0:01:28The event will see over 10,000 athletes from around 200 nations
0:01:28 > 0:01:32come together to compete in 28 sports, including athletics,
0:01:32 > 0:01:35swimming and even wrestling.
0:01:35 > 0:01:37Team GB will be hoping to win loads of medals.
0:01:37 > 0:01:40Here's the BBC's Olympic reporter Nick Hope with which British
0:01:40 > 0:01:43stars to watch out for.
0:01:43 > 0:01:44Hi, Newsround.
0:01:44 > 0:01:46Yes, we're just days away from the Rio Olympics,
0:01:46 > 0:01:50an event so big it's called the greatest show on Earth.
0:01:50 > 0:01:52Many of the athletes have already travelled to Brazil
0:01:52 > 0:01:55to begin their final preparations so here are my top five
0:01:55 > 0:02:00ones to watch in Rio.
0:02:02 > 0:02:04Teenager Amber Hill started shooting when she was just ten.
0:02:04 > 0:02:07She has her own special pink cartridges and hopes those
0:02:07 > 0:02:10will help her become the first British woman to win an Olympic
0:02:10 > 0:02:13shooting gold medal.
0:02:13 > 0:02:15Adam Peaty is a swimming sensation.
0:02:15 > 0:02:18He's won Commonwealth, European and World gold medals over
0:02:18 > 0:02:21the last two years and is looking to complete his set
0:02:21 > 0:02:25with an Olympic title.
0:02:25 > 0:02:28Britain has some of the best taekwondo fighters on the planet
0:02:28 > 0:02:30and Bianca Walkden is a major star.
0:02:30 > 0:02:36She won World gold in 2015 and wants more success in Rio.
0:02:36 > 0:02:39Ellie Downie only stepped up to senior gymnastic competitions
0:02:39 > 0:02:41last year, but has already won several major titles and will be
0:02:41 > 0:02:48bidding for both individual and team medals.
0:02:48 > 0:02:50Finally, Katarina Johnson-Thompson, the heptathlete, competes
0:02:50 > 0:02:54in a incredible seven events and is amongst the favourites
0:02:54 > 0:02:57to secure gold, but she'll be up against her teammate,
0:02:57 > 0:03:02defending champion Jess Ennis-Hill.
0:03:02 > 0:03:06So all five athletes will be hoping to win big for Team GB and you'll be
0:03:06 > 0:03:08able to catch the best of the action on the Newsround website
0:03:08 > 0:03:10throughout the Olympics.
0:03:10 > 0:03:11Thanks, Nick.
0:03:11 > 0:03:13It's hard to mistake this kind of dog.
0:03:13 > 0:03:15It's a British bulldog, of course, but scientists
0:03:15 > 0:03:17are calling for changes to the way it's bred.
0:03:17 > 0:03:21The dogs can have health problems because for centuries they've just
0:03:21 > 0:03:24been bred with other bulldogs.
0:03:24 > 0:03:26Researchers in the US think that cross-breeding with other types
0:03:26 > 0:03:31will help bulldogs survive.
0:03:31 > 0:03:32Now to a much bigger creature.
0:03:32 > 0:03:35One of the largest ever dinosaur footprints has been found in Bolivia
0:03:35 > 0:03:36in South America.
0:03:36 > 0:03:39It's more than a metre wide and is thought to have belonged
0:03:39 > 0:03:44to a type of dinosaur called an Abelisaurus.
0:03:44 > 0:03:47Amidst the dry and dusty hills of central Bolivia,
0:03:47 > 0:03:49a remarkable discovery.
0:03:49 > 0:03:54Hidden beneath rocks and boulders, a footprint preserved in time.
0:03:54 > 0:03:58A footprint that's thought to be tens of millions of years
0:03:58 > 0:04:04old and much larger than expected.
0:04:04 > 0:04:06TRANSLATION: The abelisaurus were the great carnivores of the end
0:04:06 > 0:04:10of the Cretaceous period in the southern hemisphere.
0:04:10 > 0:04:12Footprints this large have never been reported.
0:04:12 > 0:04:16Their normal size was around nine metres, large animals,
0:04:16 > 0:04:19however the footprints we found were for an animal that easily
0:04:19 > 0:04:22exceeds ten or even 12 metres.
0:04:22 > 0:04:26The Abelisaurus was similar to the Tyrannosaurus Rex.
0:04:26 > 0:04:31Both part of the Theropod group of dinosaurs.
0:04:31 > 0:04:34Like the T-Rex it's believed to have lived in the late Cretaceous period,
0:04:34 > 0:04:38somewhere around 60 to 80 million years ago.
0:04:38 > 0:04:41Whereas its more famous cousin roamed around north America,
0:04:41 > 0:04:44the abelisaurus could be found in south America.
0:04:44 > 0:04:48And it was unlikely to be lonely.
0:04:48 > 0:04:50In this area of Bolivia thousands of footprints have been discovered
0:04:50 > 0:04:55and children are getting the chance to see replica dinosaurs.
0:04:55 > 0:05:0180 million years ago they could have seen the real thing.
0:05:01 > 0:05:03And if that story's left you wondering what kind
0:05:03 > 0:05:05of dinosaur you are, well, now you can find out.
0:05:05 > 0:05:09Head online to try our new quiz.
0:05:09 > 0:05:11I've done the quiz and I'm a Terrandon!
0:05:11 > 0:05:13Now this might not be millions of years old but it's
0:05:13 > 0:05:17still pretty amazing.
0:05:17 > 0:05:19Lava from the Kilauea volcano in Hawaii started erupting two
0:05:19 > 0:05:22months ago and has been moving on a six-mile journey
0:05:22 > 0:05:25towards the coast since.
0:05:25 > 0:05:28It's now reached the Pacific Ocean and this stunning video
0:05:28 > 0:05:30shows the hot liquid rock falling off the cliffs.
0:05:30 > 0:05:34Officials there say that the lava isn't putting any towns at risk.
0:05:34 > 0:05:38And finally, people in the US caught the moment the remains of an empty
0:05:38 > 0:05:40rocket lit up the skies over Utah and California.
0:05:40 > 0:05:45The Chinese CZ-7, which re-entered the atmosphere on Wednesday night,
0:05:45 > 0:05:47left people stunned with many sharing photos and videos
0:05:47 > 0:05:51of the bright object online.
0:05:51 > 0:05:52That's all from me.
0:05:52 > 0:05:54Newsround's back at 4:20 with Jenny.
0:05:54 > 0:05:57Bye for now!
