Potential Future Disaster From Nanotechnology
There is danger from future widespread use of nanotechnology. It is seen as the new savior to save the world from food shortages and so on. But like bio-fuel production it could do more harm than good. CSIRO is calling for more study of nanotechnology. This is despite the fact that no country has yet examined safety issues involved with it.
Nanotechnology creates "micro-fine" products that have no safe disposal system. If they get into the environment there is not telling what damage they could do.
Risks are seemingly endless: use by terrorists; environmental damage; self-reproduction (goo everywhere); even the future of Mankind on this planet could be under threat.
Once a material has been modified or a new nano-product created it becomes a permanent structure. It must be chemically altered to make it safe. A nano-substance is not inert. It will act on the environment if it can. At the moment there are no restrictions. Developers can do what they wish. Let's hope regulations are put in train before a disaster occurs.

Dinosaurs Found in Australia - What is Fact?
Australia is a very old continent. It seems the ancestors of Tyrannosaurus rex lived here. A hip bone has been found here that dates to 110 million years ago which is 40 million years before T.rex roamed elsewhere on earth. Until now it was believed that T.rex only lived on Northern continents.
Many of the things stated as fact by scientists are indeed just matters of faith until they are proven otherwise. Scientists argue about when dinosaurs developed feathers and why. They claim that birds today are direct descendants from dinosaurs. This is like saying humans are descended from dinosaurs. Much evidence points to birds having a line of descent completely separate from dinosaurs.
The same rings true with the Hobbit people of Flores Island. Some scientists will not accept that people different from humans survived until 18,000 years ago alongside humans. Neanderthals lived until 50,000 years ago, so why not another type of human? Science is much like religion. What is just theory is put forth as fact. Ah, the dangers of religion - and science!
