A new lie detector, the GK-1, tested in Russia for airline security shows significant promise towards improving airline security. The GK-1, developed by Israeli firm Nemesysco, uses a minimally invasive two stage process to tell if a passenger is being untruthful.

The initial test takes between 30 to 75 seconds and can be performed as part of the standard security screening. Passengers simply put on a pair of headphones and look at a console to answer “yes” or “no” questions into a microphone. For those that fail the initial test, they are taken aside for a more extensive test.

At $10k to $30 per installation, the added speed and accuracy of the tests may be a good step towards improving airline safety and helping you get through the “line” that much faster.

A new study by Pyramid Research shows that mobile subscribers in emerging markets have high interest in mobile internet and data but little interest in paying much.

The study asked 2500 mobile phone users across the BRIC countries (Brazil, Russia, India and China) “under which of the following circumstances they would use data services like wireless internet and mobile TV - if it were free, if the price were right or not interested at all”.
