:00:00. > :00:09.Hi, guys! Ayshah here with the last word on CBBC today. We've got big
:00:10. > :00:13.beards and super specs coming up on Newsround.
:00:14. > :00:18.But first an internet security expert's been telling Newsround what
:00:19. > :00:22.you need to do to protect yourself from the computer bug heartbleed.
:00:23. > :00:24.It's hit the headlines recently after affecting Android devices and
:00:25. > :00:29.being detected by big internet companies like Google and Facebook.
:00:30. > :00:34.Heartbleed is a flaw that allows hackers to access info via the
:00:35. > :00:38.websites we use. Most sites have fixed the problem but no one knows
:00:39. > :00:41.how much info hackers might have gathered. Our expert's told us you
:00:42. > :00:46.should change your passwords to be safe. And you can find out what
:00:47. > :00:50.other advice he has as well as the difference between a computer bug
:00:51. > :00:53.and a virus on our website now. Next, if you've ever struggled to
:00:54. > :00:57.look like you're listening properly - listen up. A professor in Japan
:00:58. > :01:00.has come up with a set of super specs to solve that problem. They
:01:01. > :01:04.have two computer generated eyes that react to the person who's
:01:05. > :01:09.talking to you and make you seem interested and focused, even if
:01:10. > :01:13.you're miles away. And the latest trends are hard to
:01:14. > :01:16.keep up with but if you feel like you're constantly out of line with
:01:17. > :01:20.the up to the minute fashion then don't worry. A new study on beards
:01:21. > :01:22.says there's a scientific reason for it. Here's Nel.
:01:23. > :01:25.Bushy ones, cropped ones, shaped ones - beards have come in all
:01:26. > :01:30.shapes and sizes over the centuries, and recently it seems that having
:01:31. > :01:33.facial hair is back in fashion. A whole host of celebrities have
:01:34. > :01:38.jumped on the beardy band wagon - making them the coolest must-have
:01:39. > :01:41.for men. But does more and more people growing facial fuzz actually
:01:42. > :01:47.mean it's starting to lose its appeal? Researchers in Australia
:01:48. > :01:50.certainly think so. They showed people different pictures of faces
:01:51. > :01:53.and found the more beards they saw, the less cool they thought they
:01:54. > :01:57.were. Something that feeds into a much wider issue, that when things
:01:58. > :02:00.become really popular - people no longer like them. So the next time
:02:01. > :02:04.you think you're setting a new trend by doing something a little bit
:02:05. > :02:12.different, just beware. Fashions are complicated. Negative frequency
:02:13. > :02:17.means things that are rare and enjoy a currency and a more -- are more
:02:18. > :02:20.attractive when the rare van when they are common.
:02:21. > :02:22.Because the minute everyone joins in - there's a chance it'll go from
:02:23. > :02:31.brilliant to boring! And you've been telling us your
:02:32. > :02:41.thoughts on what's lost the cool factor. Joe says...
:02:42. > :02:44.Sarah says, I thought fist bumping was cool until my parents started to
:02:45. > :02:56.do it. I will dance to that. Backed by
:02:57. > :02:59.morning!
