1. new device can track multiple people without sensors
ORLANDO, Fla., Nov. 30 (UPI) -- The world's first device capable of tracking multiple people without attached sensors is here, and scientists see in the invention opportunities for more efficient military training and warfare readiness.
Orlando-based Organic Motion computer vision company unveiled the tracking platform at the Interservice Industry Training, Simulation and Education Conference, the world's largest of its kind that opened Monday at Orlando's Orange County Convention Center.
Tracking devices have different uses, none more challenging than in a modern warfare scenario where soldiers can end up in dangerous, unpredictable situations and lose contact with their commanders, often with disastrous results.
The new motion tracking platform, OpenSTAGE, does not require participants to wear any attached devices, tags or sensors. The technology enhances the operations of a wide range of simulated training environments and is apparently effective in tracking multiple people at the same time, without special backgrounds or controlled environments.read more @ upi asia
2. Antarctica may heat up dramatically as ozone hole repairs, warn scientists -- NOT THAT YOU CAN BELIEVE ANYTHING SCIENTISTS SAY ANYMORE.
The hole in the Earth's ozone layer has shielded Antarctica from the worst effects of global warming until now, according to the most comprehensive review to date of the state of the Antarctic climate. But scientists warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3C on average, with melting ice contributing to a global sea-level increases of up to 1.4m.
The western Antarctic peninsula has seen rapid ice loss as the world has warmed, but other parts of the continent have paradoxically been cooling, with a 10% increase in ice in the seas around the region in recent decades. Many climate change sceptics have used the Antarctic cooling as evidence against global warming.
But John Turner of the British Antarctic Survey said scientists are now "very confident" that the anomaly had caused by the ozone hole above Antarctica. "We knew that, when we took away this blanket of ozone, we would have more ultra-violet radiation. But we didn't realise the extent to which it would change the atmospheric circulation of the Antarctic."read more @ guardian
