:00:00. > :00:07.Hi guys. Ayshah here with how you can make sure you're in fashion
:00:08. > :00:10.thanks to a new study about beards. Plus the super specs that can
:00:11. > :00:19.convince people you're paying attention. This is Newsround.
:00:20. > :00:24.But first to the warning that Ukraine could be on the brink of
:00:25. > :00:27.civil war. There's been lots of unrest there over the last few
:00:28. > :00:30.months but today tensions are rising fast. Ukrainian troops have started
:00:31. > :00:33.a fight back against armed groups who want nearby Russia to have more
:00:34. > :00:41.control in the country. Here's Ricky with more. Tanks like these have
:00:42. > :00:47.been spotted in east Ukraine. They are from the Ukrainian army but not
:00:48. > :00:50.everyone wants them here. In recent days armed pro-Russian groups have
:00:51. > :00:54.taken over government buildings and airports in ten towns and cities.
:00:55. > :00:58.Those groups want Ukraine to be closer to Russia. But now Ukraine's
:00:59. > :01:04.army says it's going to fight back and stop that from happening.
:01:05. > :01:07.Overnight they took back an important airfield from pro-Russian
:01:08. > :01:10.fighters. But many local people don't trust the Ukrainian government
:01:11. > :01:16.and don't want Ukrainian soldiers in their towns and cities. In the city
:01:17. > :01:23.of Kramatorsk, Ukrainian army tanks were stopped in the road, the BBC's
:01:24. > :01:27.reporter James Reynolds was there. This morning I saw an awful lot of
:01:28. > :01:34.shouting between Ukrainian army and the gunmen who like Russia. Nobody
:01:35. > :01:38.really knows how it's going to end. Some pub -- Biddle worry about there
:01:39. > :01:42.being a big war but ordinary people around here having their lunch,
:01:43. > :01:45.feeding the pigeons, they say they don't want war. They love the
:01:46. > :01:49.Ukraine and they also love their neighbour, Russia. And this shows
:01:50. > :01:51.how complicated the conflict is. In the city of Donetsk pro-Russian
:01:52. > :01:54.groups continued their takeover, invading the town hall. Russia's
:01:55. > :01:59.president Vladimir Putin's warned Ukraine's on the verge of a full
:02:00. > :02:04.civil war. But the UK and America say he is to blame for many of the
:02:05. > :02:07.recent problems. The worry for people watching the crisis is that
:02:08. > :02:14.having troops from two sides in the same area makes this a very
:02:15. > :02:17.dangerous moment for Ukraine. Thanks, Ricky. There's loads more on
:02:18. > :02:20.the background to everything that's happened during the Ukraine crisis
:02:21. > :02:24.so far on the Newsround website right now. And that's also where you
:02:25. > :02:28.can find out all the Heartbleed computer bug. It's hit the headlines
:02:29. > :02:34.recently after affecting android devices, computers and big internet
:02:35. > :02:37.companies like Google and Facebook. Heartbleed is a flaw that allows
:02:38. > :02:42.hackers to get access to sensitive information via the websites we use.
:02:43. > :02:45.Most of them have fixed the problem now but no one knows how much info
:02:46. > :02:51.hackers might have gathered. Experts say you should change your passwords
:02:52. > :02:56.just to be safe. Now the latest trends are hard to keep up with. But
:02:57. > :02:59.if you've ever worried that you always seem to be getting into
:03:00. > :03:02.things just as they're going out of fashion don't worry. The people
:03:03. > :03:07.behind a new scientific study on beards say there's a good reason for
:03:08. > :03:11.it. Here's Nel. Bushy ones, cropped ones, shaped ones. Beards have come
:03:12. > :03:14.in all shapes and sizes over the centuries, and recently it seems
:03:15. > :03:18.that having facial hair is back in fashion. A whole host of celebrities
:03:19. > :03:27.have jumped on the beardy bandwagon making them THE coolest must-have
:03:28. > :03:30.for men. That does more people growing facial fuzz actually mean
:03:31. > :03:33.it's starting to lose its appeal? Researchers in australia certainly
:03:34. > :03:36.think so. They showed people different pictures of faces and
:03:37. > :03:40.found the more beards they saw, the less cool they thought they were.
:03:41. > :03:43.Something that feeds into a much wider issue, that when things become
:03:44. > :03:51.really popular people no longer like them. Fashion is a combo gated thing
:03:52. > :03:58.and will be interesting dynamics comes of genetics, and what that
:03:59. > :04:01.means is things which are rare, enjoyed a currency. They are more
:04:02. > :04:05.attractive when they are rare than if those same things were common. So
:04:06. > :04:08.the next time you think you're setting a new trend by doing
:04:09. > :04:11.something a little bit different, just beware. Because the minute
:04:12. > :04:19.everyone joins in there's a chance it will go from brilliant to boring.
:04:20. > :04:23.I like that hat. You can join the chat on what's cool and what's not
:04:24. > :04:26.on the website right now. And we'll hear what you've had to say back
:04:27. > :04:29.here at 6.50pm. But last up, if you've ever struggled to look like
:04:30. > :04:33.you're paying attention when you're not then listen up. A professor in
:04:34. > :04:37.Japan has come up with a set of super specs to solve that problem.
:04:38. > :04:40.They have two computer generated eyes that react to the the person
:04:41. > :04:50.who's talking to you and make you seem interested and focused, even if
:04:51. > :04:55.you're actually miles away. That's very interesting. That's your lot.
:04:56. > :04:57.Newsround's back at 6.50pm. Bye bye.
