New trend on the web
Google Science Fair
For you young inventors and future scientists out there, here's a chance to show your stuff. Google is hosting its second annual science fair. Students worldwide can submit their science projects online for a chance to win. The guidelines are fairly simple. Students need to think of a question or problem that interests them, and then carry out experiments to back up their conclusion. Projects can be submitted as a video or presentation.
Students aged 13 to 18 can enter, either individually or in a team of two or three. The projects must be submitted by April 1.
Google will choose 15 finalists to go to the company's headquarters in California, where they will present their projects to a panel of judges. Winners will be chosen from three age categories. The prizes? Scholarships and a trip to the Galapagos Islands with National Geographic.
Last year, more than 10,000 students from 91 countries entered the contest. So start asking questions!
Almost anyone can make their photos look like film negatives these days. Those fancy filter apps on smartphones make it easy to create crazy pics. But this isn't just any negative photo. Notice the three dots on her nose? If you stare at the red one for 30 seconds and then look over to a blank white space, you'll see the 'correct' version of the image. Can you see it?

The latest case of crime-fighting social media took place in Boston, in the United States. Last week, a popular restaurant was robbed by three suspects. Instead of waiting for the police to investigate, the owner took to the internet to try to catch the criminals. On its Facebook and Twitter accounts, the restaurant announced a US$1,000 reward for any tips leading to arrests. It even posted a surveillance video of the crime on YouTube.
This unconventional method of crime-solving seemed to work. The owner received a number of responses including one described as a 'juicy tip'.
Once again, the power of the internet prevails.
