Paint to Make Things Invisible

If you move as fast as superman you may be able to make yourself invisible, but for the ordinary person it is just not possible. Theories exist though that "prove" it is possible to make yourself invisible. Doctor Jensen Li and Professor John Pendry have written a paper which surmises making invisible paint.

Such material has to be extremely thin, having a structure smaller than the wavelength of visible light. Scientists have already made a small object invisible by cloaking it in a material comprised of tiny structures. If a material can be developed from nano-sized pieces it could be painted on an object and it would "bend" the light away from sight, i.e., the background would be visible.

Such a material has to be made from silica and silicon because variation in interpreting light is necessary. A person viewing a cloaked object would see a mirage of the background. Don't be too hasty though - we are not in the Star Trek world yet. A person would experience only an illusion of the background!

Albert Einstein's Genius Was Due to His Unusual Brain

Albert Einstein wasn't only a genius her was a very odd human being. His brain shows peculiar differences from the norm; it had many more folds than the average person. This gave the brain a greater surface area. It is like using a larger computer to do calculations. Upon his father's death in 1955, Thomas Einstein gave the pathologist permission to preserve the brain of Albert Einstein. It was photographed then dissected into 2,000 ultra-thin slices. The slices and slides of them were later distributed to researchers. The brain had more neurons and glia cells, well outside of the normal range; pariental lobes were unusual in the pattern of ridges and grooves. Einstein only had a brain of average size. The area controlling the tongue and face was larger, as was the region that involves attention and planning. Overall, Einstein's brain was complex. Many people think in words. He said his thinking was like a physical activity. If selection based on "healthy...

New Species Found in Australia

An endangered animal, Antechinus, has two new members. Well, they have been there all along. A team from Queensland University of Technology discovered the Tasman Peninsula Dusky Antechinus (Antechinus vandycki) in south east Tasmania, and nominated the Mainland Dusky Antechinus   (Antechinus mimetes) . The latter was known to be in New South Wales and Victoria but it is now a species in its own right. The Tasman Antechinus is about 13 cm long with a short tail weighing roughly 90g. It is located in Port Arther, Tasmania. Under threat from clearing of trees it resides in state forest in fragmented groups.  Survival is precarious in the isolated stands. While uncovering new species is rare in developed countries, new ones are being found in Australia all the time. This is due to the low population density of people in inland Australia. Unfortunately, new species when found are usually in small numbers and under threat. Antechinus are not helping themselves...
