Volcanic Chain Found in Australia

Scientists have always said that Australia is the safest country on earth in regard to volcanic eruptions and earthquakes.  Now we find that this is totally wrong.  A massive volcanic chain has been discovered stretching from Hillsborough in central Queensland in a straight line down to Cosgrove in Victoria, then into the sea.

The Australian continent has moved right over the top of the chain leaving volcanoes under the sea in Bass Strait.  Yellowstone in North America is only a third as long as the new Australian hot spot.  It is unusual because it is not located on a tectonic plate boundary.  This type of volcanic chain was not thought to exist.

A weakness above a mantle plume has allowed volcanoes to break through to the surface.  The mantle is 3,000 kilometers below.  The Cosgrove hot spot could become active especially in the south where it is younger.  This could happen as the Australian tectonic plate is the fastest moving on the planet.

Active volcanoes normally exist where the mantle is less than 100 kilometers thick on average.  Cosgrove is 150 kilometers thick at its greatest.  This is not a law for activity.  Eruptions are still possible.  Seismic activity is occurring off the north coast of Tasmania.

More Expensive Eggs - "End" of Battery Hens

Coles and Woolworths promise no support for battery chickens and pork grown in like manner. They say they will only purchase from "green" suppliers. Is this being good citizens on their part? Well frankly, it is not. Controlling 80 per cent of the market they have the power to force low prices on more expensive production.

We will see small operations go to the wall and a future oligopoly forming. When this is finalized, like in the paint market, buyers will have to pay the price offered by the few gigantic producers. For example, Bunnings has to take prices of the few paint manufacturers. Furthermore, there is nothing to stop backyard battery operations selling at weekend markets.

Legislated changes have unintended consequences. The result will be more expensive eggs. This has to be the case. Higher costs mean higher prices overall. This is economic fact. Get ready to see cardboard signs nailed to front fences of houses selling "home grown" eggs.

Earliest Lifeforms Were Like Baseballs, Tennis and Soccer Balls

Earliest life on this planet looked like tennis and soccer balls. Images show round ball-like creatures. One type has the curved line around it like a tennis ball. Another has five sides shapes around its surface like a soccer ball.

At first the lifeforms were believed to be giant bacteria. Currently the verdict is they are metazoan embryos. They could ultimately be found to be protists such as fungi, algae and diatoms.

Though they are the earliest kind of life found, the find at this particular site in China is just by chance. Different life could have developed elsewhere. Two animals have also been found at the site that lived during the "Snowball Earth" period. One of the animals could be the first instance of a bilateral, life with a symmetrical body.

China and Australia were once joined together on the supercontinent of Gondwana. Fossils in the Flinders Range of Australia also claim the "ticket" for the oldest known form of life.
