It's not unusual for schools to ban mobile devices during class, but it's a different story at Nan Chiau Primary School in Singapore. Here, 350 third-graders gaze and poke at Windows phones while their science teacher elaborates on their assignments for the day. The students are free to shoot photos and videos using their Nokia Lumia 710 smartphones to help them remember what they've learned.

Using an app called myDesk -- developed by undergraduates at the University of Michigan -- the students make diagrams and concept maps, as well as append text and photos to their assignments. Teachers are also able to use the app to review the work submitted and leave feedback. … Read more

Coming soon: A Breathalyzer for pot and cocaine?

Some people drive high.

They shouldn't, but they're high, so they don't really know what's good for them and what isn't.

Should they get stopped by police, the long nose of the law can sometimes sniff the presence of marijuana in their car.

Should they happen to have nosed their way into some cocaine, there might be traces of white powder around their nostrils.

Scientists in Sweden, however, believe they have made some progress in creating such a device.… Read more

See the Samsung S Translator app in action

We put the S Translator app found on the new Samsung Galaxy S4 in action in the below video, and tested out two phrases in different languages. The first is, "Excuse me, where is the hospital?" and the second is, "Let's go to the mall."

Our verdict: It's not too bad, but you will need a data connection for this to work. Which means that if you're traveling, you will need to pay for a data roaming plan to make full use of this (or hope to get on free Wi-Fi networks).

In this scenario, it's probably better to use an offline-capable app such as Google Translate, which works just as well for the basic phrases we used and features an offline mode for when you need to travel overseas. … Read more
