Police and union leaders across the country expect big crowds during today’s National Community Day of protest against the Federal Government’s WorkChoices proposed changes to industrial relations laws.

The Australian Council of Trade Unions (ACTU) predicts hundreds of thousands of people will demonstrate in Sydney and Melbourne. Protest meetings in other capital cities are expected to attract workers in their tens of thousands. The rallies will take place in 300 regional sites across Australia.

Labor’s opposition spokesman on industrial relations, Stephen Smith says, “The more people become aware of the nature of the changes and the detail of the changes, the more they realise how vulnerable they are and the more they want to do something to prevent the changes.”

Mark Bethwaite, from Australian Business Ltd, believes most people will go to work as usual. “Because frankly they are not convinced by the scare campaign the ACTU has been running,” Mr Bethwaite said.

The Federal Government has been accused of instructing agencies to refuse staff leave to attend the rallies against its IR changes and says it will not be affected by a rally of one person or a 100,000.

The Federal Department of Workplace Relations has issued advice to other departments that employees wanting to attend the National Community Day of Protest should be denied leave.

State and territory leaders intend to mount a High Court challenge to the Federal Government’s proposed industrial relations changes.

The ACTU say, “the IR changes are not just an attack on workers – they fundamentally undermine the values that make Australia great. Beneath all the glossy advertising are proposals that will unfairly curtail your rights at work, cut the amount of time you can spend with family, and erode your job security.”

The federal government have spent over fifty million dollars on promoting the radical new changes.

Unions say the changes will make it easier for workers to be sacked; cut take-home pay and reduce minimum standards; change the way minimum wages are set to make them lower; replace the award safety net with just five minimum conditions; restrict access to unions; make it harder for employees to bargain as a group; and reduce the powers of the independent Industrial Relations Commission.”

In Melbourne, Australian Education Union’s Mary Bluett said the IR legislation “is not the legacy we want to leave our children.” About 12,000 public servants, 10,000 building workers and hundreds of nurses are also expected to join the protest, but workers operating road, train, tram and bus services will remain on duty to allow commuters to travel free to the rally.

Sky News estimated the number attending the rally in Melbourne as 175,000.

The Australian Chamber of Commerce and Industry labelled the rally “a tired union stunt”.

The name Robert Cailliau may not ring a bell to the general public, but his invention is the reason why you are reading this: Dr. Cailliau together with his colleague Sir Tim Berners-Lee invented the World Wide Web, making the internet accessible so it could grow from an academic tool to a mass communication medium. Last January Dr. Cailliau retired from CERN, the European particle physics lab where the WWW emerged.

Wikinews offered the engineer a virtual beer from his native country Belgium, and conducted an e-mail interview with him (which started about three weeks ago) about the history and the future of the web and his life and work.

Wikinews: At the start of this interview, we would like to offer you a fresh pint on a terrace, but since this is an e-mail interview, we will limit ourselves to a virtual beer, which you can enjoy here.

Robert Cailliau: Yes, I myself once (at the 2nd international WWW Conference, Chicago) said that there is no such thing as a virtual beer: people will still want to sit together. Anyway, here we go.

The International Monetary Fund and the European Union approved aid packages to help Georgia recover from its conflict with Russia, which occurred in early August. The IMF approved a US$750 million loan which will allow Georgia to rebuild its currency reserves. The European Union also approved an aid package of €500 million in aid by 2010, which is expected to help internally displaced people (IDPs) and economic recovery in the form of new infrastructure. Only €100 million of the EU aid will be given to Georgia this year.

These loans are aimed to restore confidence in Georgia’s economy and send a signal to international investors that Georgia’s economy is sound. According to the IMF, international investors have been “critical to Georgia’s economic growth in recent years.”

Takatoshi Kato, Deputy Managing Director and Acting Chairman of the IMF executive committee, said the loan will “make significant resources available to replenish international reserves and bolster investor confidence, with the aim of sustaining private capital inflows that have been critical to Georgia’s economic growth in recent years.”

Georgia has requested $2 billion in international aid to help it recover from the conflict. So far, the United States has pledged $1 billion in aid. Further assistance and loans to Georgia are expected from other organizations. Kato noted that “…Georgia is expected to receive financial assistance from multilateral and bilateral donors and creditors in support of the reconstruction effort.” It is expected that an international donors’ conference will take place next month to solicit more aid for the country.

Georgia’s government expects that economic growth will be more than cut in half as a result of the conflict. Last year, Georgia’s GDP increased 12.4% and it is predicted by the IMF that growth will be less than 4 percent in the coming year.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.
