Invisibility Cloaks and Thirsty Koalas
We are on our way to obtaining Harry Potter's invisibility cloak. Professor Susumu Tachi of Tokyo University has fabricated a coat that appears to be invisible. This is made possible by a viewfinder that puts together the image from behind the person wearing the coat. Check this link for more information. Note that the image retains its proportion even though part of the coat is wrinkled.
Are koalas vicious? They appear quite docile, but have talon-like claws. The city of Gunnedah, in Australia, has relied on the koala population to bring in tourists. Currently, with the drought conditions in Gunnedah, koalas are turning to the residents for water. Locals have noticed increasing numbers of koalas drinking from taps and containers of water. Normally, koalas get their moisture from the leaves they eat.
