Camera Traps Catch Eye of the Tiger

...o avoid the area in the future. Due to the moist, hot climate of Sumatran forests, the cameras often malfunction, so scientists will be lucky if two-thirds of the pictures are of any animals. Because they had conducted thorough research to determine likely tiger habitat, WWF scientists got their first t...

...e used to prevent exposed tissue from becoming too hot and damaged. Pulsed-HIFU instead renders tissues permeable and helps target them for taking up genes and other therapeutic substances injected into the body. "Basically, we're using sound waves to open up the tissue by producing gaps between the cel...
