Wiki World: discovered

There seems to be a scientific breakthrough every minute. You go onto the Internet and a new claim appears. Some of course is recycled old news. However, new discoveries are made all the time. Despite spending cutbacks in some countries, science seems to be leaping ahead.

You would think that just about everything is known about the body. Nevertheless, a new stem has been found. A four continent research enterprise called Project Grandiose has identified the new cell which has been put into the "F-class": the cell has a fuzzy body when viewed on a microscope.

It is hoped that the cell can be used in the treatment of injuries and illnesses. The days of using stem cells from afterbirth material are long gone. Adult cells can now be modified for treating various health problems, but this is early research. The only successful treatment to date is for macular degeneration.

Targeting modified stem cells is the main problem. They are like tumours and in the wrong place they can cause damage. The new cell indicates that it could treat diabetes. Producing them on a large scale is the next big issue for the third class of pluripotent cells yet discovered.

When Captain Cook "discovered" Australia in 1770 it was known that Southeast Asians and even Chinese seafarers had landed in Australia. Portuguese and Dutch ships had also stopped to replenish water supplies. It was not considered possible that people had landed in Australia from another continent.

In the 1940s mysterious coins were discovered. While some were coins used by the Dutch East India Company others were identified as coming from the Kilwas Sultanate of Tanzania in Africa. They were used in the prominent trading center 1,000 years ago.

If Africa was trading using Australia as a location en route Aboriginals could have come into contact with African merchants. Though the coins were found on the fringe of the Australian north coast, getting fresh water would have been important for ships traveling through the waters of the Wessel Islands.

Aboriginals would have been curious about any "strange" looking new people. Africans would certainly have been different. Drawings of European ships have been found on cave walls. They were drawn by Aboriginals after contact with Europeans. Perhaps evidence of African visitations can be located.
