LONDON, England - July 5, 2011 - It's a standard scenario across the world - the computer crashes and we scream exactly what we think at the flickering screen.

But we may soon have to learn to bite our tongues - or risk the wrath of being shouted at by the machine we've just cursed.

This is because scientists are building a voice-activated device that can interact with people in a “natural and intelligent way”.

Artificial intelligence will help it become familiar with a user's voice, with the ultimate goal that it can understand, speak and behave like a human.

LONDON, England - June 17, 2011 (PNN) - A new generation of battery-free surveillance devices, which can be implanted under the skin and transmit over huge distances via wireless, have been developed by scientists.

Researchers are working on nano machines that could be injected into the arms of patients and then report back to doctors who are monitoring them from miles away.

WASHINGTON - June 9, 2011 - Billing it as a way to end the one-size-fits-all approach to airport security, the International Air Transport Association on Tuesday unveiled a mock-up of what it called the "Checkpoint of the Future."

Instead of a single screening procedure applied to all fliers, the group envisions that passengers would be divided into risk categories based on information available about them. They would then be directed to one of three lanes: "Known Traveler," "Normal" and "Enhanced Security."

With the rise in technology, robots are getting smarter and closer to the living objects they resemble. Here is a smart robot bird FESTO, which looks exactly like a real bird while flying in the air. FESTO can use its wings like bird, and move its tail and head to make anybody believe that it is a real bird flying near them.
