"I can't be your mom all your life."
Europe Will Bring the World into Depression
The European economic situation is becoming a world problem. There seems to be no way the Euro can be saved. There will definitely be a flow-on effect to the world economy. Despite the new agreement, without the UK, nothing has really changed. The regulation and punishment for spending too much is too late for Greece, Spain, Portugal, Ireland and Italy. When these countries ultimately default, and they will, France and Germany will be drawn into Depression with them because their banks have continued to lend to these deficit countries.
There will be another problem in Europe that no one has highlighted. When unemployment gets too high in the struggling countries life will be unbearable. Labor is free to move across borders in the EC. Workers will move to where the work this. That is Germany and to a lesser extent France. Economic refugees will flood across the borders. The UK will not be exempt from this. For centuries England, Scotland and Wales have been destinations for workers from Ireland leaving due to lack and work and political problems. When Ireland defaults hundreds of thousands will move out.
Welfare systems in these "target" countries will be burdened to the extreme. Unemployment benefits will have to be reduced, per person, to cope. Lack of demand in Europe means lower production in the US and Asia. The future also looks bleak for Australia, the main provider of basic resources to China.
Going for a budget surplus in 2012 may be politically justified and the Australian Government may just make it in time for the next election with tough cutbacks. However, no matter which political party wins government it will have to go straight back to spending to keep the Australian economy moving with the sharp cutbacks forced on China by the failing world economy.

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.

New Chip For Proposed Square Kilometer "Telescope"
CSIRO has made a new chip for the Square Kilometer Array (SKA). A decision on where the SKA will be located, Australia or South Africa, has yet to be made. The new telescope array will analyse data from small radio dishes spread over a 3,000 kilometer area.
Silana is working with CSIRO on the chip made of silicon-on-sapphire (SOS). It is designed for the mid-band range (500MHz - 2GHz). The unit is a one piece integrated circuit board replacing the multi-unit board previously used for this process.
The new SKA "telescope" will be the largest ever built and it will give high resolution images of distant parts of the universe. Though the array will evaluate a wide range of frequencies, the mid-range is important as it is the emission line for hydrogen which gives the distribution of galaxies and stars.

Baby Turtles Communicate So They Hatch Together
Baby turtles hatch all at the same time. This is no accident: they communicate with each other while they are still buried under the ground. Some eggs are deep down where it is cooler. Others are near the surface where the sun heats the eggs up. As hatching gets closer those further down speed up their development while those higher up slow down.
University of Western Sydney researcher Ricky-John Spencer randomly collected turtle eggs then put them into two groups. One group was incubated at 25 degree Centigrade, the other group are 30 degrees. They were then all brought together and kept at the same temperature: they all hatched at the same time.
Jessica McGlashan took a closer look. She brought a female turtle into the lab and collected the eggs the turtle laid. One half of the eggs were put into the incubator at 30 degrees, While the other half received 26 degree incubation. Some eggs from both temperatures were then put into one group in the incubator at the higher temperature and those who had been initially incubated at 26 degrees were tested. They did indeed develop faster.
A group eggs was kept at 26 degrees throughout. As the days went by the faster developing embryos who were now at 30 degrees exhaled more carbon dioxide and their heart rates were faster than the embryos kept at 26 degrees.
Baby turtle don't actually communicate verbally, but they can "hear" each others heart beat, or rather feel the vibration of heart beats because the eggs are touching. They could even be measuring the carbon dioxide level.

Biology
Sauropods Had Hollow Bones in Their Skin
Long-necked dinosaurs had hollow bones in their skin according to fossils in Madagascar. The animal in question is the giant Rapetosaurus. Hollow bones are found in the skin of reptiles and a few mammals. These skin bones are called osteoderm.
Dinosaurs with hollow skin bones are Titanosaura, a Sauropod, Rapetosaurus, Stegosaurus and Ankylosaurus. It is believed that the bones stored mineral for hard times. Rapetosaurus, for example, had only a few bones spread throughout their skin, so the bones were not used for defence or to moderate temperature.
The fossils in Madagascar were of Rapetosaurus. What applies for Rapetosaurus can be used to evaluate the hollow bones of other dinosaurs. It cannot be ruled out that Titanosaura used the bones partially for defence but the main function of hollow bones was to store minerals.

Research Predicts the Consequences of Global Warming on Pacific Nations
Nations in the Pacific are the first to be affected by global warming. The tide is literally coming in higher and higher. Children play in sea water as it enters homes built on the highest points available on small islands. The Australian Government's Pacific Climate Change Science Program (PCCSP) has released a report on the Pacific region.
The last decade has been the warmest ever recorded. Acidity in sea water is also rising because there is more carbon dioxide. Cyclones are predicted to increase with greater rainfall. Day and night temperatures will be higher.
While the report will help Pacific nations show what damage has been done by the developed world, it is doubtful advanced countries will assist financially. Knowing what will happen will help island nations plan for the future though the changes are already apparent as the sea takes over the land.

To Swear Or Not To Swear
Eighty per cent of people swear every day including children. The little ones don't just get this habit from parents. Some children are awake late at night and hear it on television.
In different eras there are new sets of popular swear words. Words such as "bloody hell" and "bugger" were once really offensive, Today they are not treated as swear words any more. Personally, I find phrases containing the word "shit" quite off-putting. Hearing "bullshit" and "shitloads" tends to create images in the minds of listeners. It makes one move away from the speaker.
The question is - Does swearing do any harm? It does lower the "status" of an occasion if someone begins swearing when everyone else is in formal mode. One wouldn't swear when university degrees are being given, but at the pub swearing is almost expected particularly in the public bar.
Swear words are just sounds like other words. The sounds, however, do have meaning. Policing the use of offensive words would be impossible, People are regularly fined for swearing at police officers. It does not change behavior. They continue to swear afterwards. The more swearing there is, the sooner such words will be accepted in normal speech.

Man Caught Deep Ocean Fish 42,000 Years Ago
Our ancestors not only fished rivers and the coastline. They caught marine food in the deep ocean. It is known that people travelled across oceans 50,000 years ago. However, proof that they could catch fish in the deep sea went back only 12,000 years.
New evidence shows that Man ate fish from the ocean further back than 12,000 years. In caves on the island of East Timor remains of tuna and other large fish have been found.
East Timor was "out of bounds" for paleontologists until recently because of the ongoing troubles with Indonesia. Information on ancient Man is changing scientific knowledge about our ancestors. Bone fish hooks dating back 42,000 years have been found there.
The diet of early Timorese was varied. It included birds, rodents, bats, snakes turtles and fish. Few large animals lived there. Half of the fish found were tuna, a fast moving fish that would have taken great skill to catch. Using nets was the only way, so they had an advanced culture.
