Water pollution affects the ecology and economy of an area.Biomagnification is the accumulation of a substance up the food chain by transfer of the pollutant in smaller organisms that are food for larger organisms in the chain. It generally refers to the sequence of processes which results in higher concentrations in organisms at higher levels in the food chain (at higher trophic levels). These processes result in an organism having higher concentrations of a substance than is present in the organism's food. There is evidence that some carnivores at the ends of longer food chains (e.g. larger fish, birds of prey, HUMANS) can then accumulate the water pollutant from eating down in the food chain.

HD-Touch is the name for an ecology of devices that are 'hi-definition'. Here, HD refers not only to the HD resolution of the LCD screen, but also to the high-degree of tactile and tangible input the system affords. The main platform is a true HD quality LCD screen that couples as a touch and object sensitive surface. While multi-touch input technology is common, I am working on expanding the range of touch and physical sensing this system allows. This includes object sensing, pairing with mobile devices, detecting when hands and devices are hovering over the surface, and object-grasping. My vision for this work is to develop the infrastructure necessary to allow cheap, quick, and robust prototyping of high quality multi-touch and tangible interfaces.

NATURE reveals the importance of an unlikely partnership between a regal tree and a tiny wasp in THE QUEEN OF TREES. Located a NATURE reveals the importance of an unlikely partnership between a regal tree and a tiny wasp in THE QUEEN OF TREES. Located along the riverbanks of southern Kenya, the sycomore tree is the centerpiece of an extraordinary ecosystem, producing several tons of fruit a year and feeding more different types of animals than any other kind of tree in Africa. It may be one of nature's oddest couples: a tiny wasp that can barely be seen, and a giant fig tree, the sycomore, which shelters a remarkable menagerie of wildlife among its limbs. The wasp and the fig depend on each other for survival. Without the wasp, the tree could not pollinate its flowers and produce seeds. Without the fig, the wasp would have nowhere to lay its eggs. THE QUEEN OF TREES shows this delicate dance of survival in exquisite detail, including spectacular close-ups of the wasp's remarkable life inside a ripening fig. To capture such incredible images, filmmakers Victoria Stone and Mark Deeble spent two years camped out near a giant sycomore fig in Kenya's outback, documenting the tree's pivotal role as a source of food and shelter for everything from gray hornbills, Africa's largest bird, to swarms of invading insects searching for food. In a surprising turn, some insects come to the tree's aid -- sparking a battle you won't want to miss.
