Submission + - 800-year-old Farmers Could Teach us How to Protect the Amazon (

An international team of archaeologists and paleoecologists, including Dr. Mitchell Power, curator of the Garrett Herbarium at the Natural History Museum of Utah and assistant professor in the Department of Geography at the University of Utah, report for the first time that indigenous people, living in the savannas around the Amazonian forest, farmed without using fire.

Submission + - Psyko offers new approach to surround sound headph 1

EconolineCrush writes: Surround sound makes games and movies much more immersive, but it hasn't translated well to headphones. No one's come up with a surround headphone design that's really caught on, and software-based speaker virtualization schemes don't always work right.

It's a unique approach, and one that reportedly offers a lot of positional audio precision. However, the heaphones appear to otherwise have rather poor sound quality, which seems like a tough pill to swallow given their $300 asking price.

The Tech Report finds out.
