Telstra Discards 50 Percent of Australia's Copper Infrastructure

Technology: Telstra is being dishonest and is treating Australian consumers like fools. Telstra is doing something that the federal government did not foresee. The telco is only using half of the nation's copper wiring originally laid a century ago. In Australia there are two pairs of telephone wires in the cable laid to each house. This was to enable each house to have two telephone connections. The system worked well with ADSL: each phone could have its separate modem and ADSL service. With the NBN this has all changed. When the NBN began its roll out it allowed Telstra to set the rules. Telstra chose the rule: ONE PROPERTY ONE NBN CONNECTION. This is fine if you have a detached house. However, if you have a granny flat that has its own phone because the main telephone line has been split at the box on the house, one line will be scrapped and will no longer be used. It will lay dead in the ground forever due to Telstra's policy. Furthermore, if you rent out

Australian and Mediterranean Great White Shark Evolution

Luck plays a large part in evolution. Climate suddenly changes and if by chance a species of animal carries suitable genes to flourish in the new environment that animal lives on. Other species die off because they cannot cope. New findings about the great white shark highlights this. Australian great whites and the Mediterranean type have genes that point to common ancestry. It is believed that a few related female sharks split up. Some going north to the Mediterranean from the larger gene pool in the south, or they peeled off from the main group in the Atlantic some going north the others going south. Narrow channels in the Mediterranean stopped this group from rejoining the Australian gene pool. This happened 450,000 years ago. Mutations since that time make the timeline clear. It is believed that swordfish and tuna the main food of the great white also split off from the their main groups. Great white sharks followed the food supply. http://www.adventure--australia.blogspot.com
