The Australian government has confirmed it will send an extra 200 troops to Afghanistan as part of a security and reconstruction team. Prime Minister John Howard says troops will leave from late July and will spend about two years in Afghanistan separate from the Special Forces and commandos already serving there. In a press conference in Canberra today, Mr Howard said the deployment was “further evidence of the government’s ongoing commitment to assist the people of Afghanistan in consolidating their embrace of democracy and resisting any attempt on the part of the Taliban to come back.”

The Australian Greens oppose the deployment of new troops. In a press release, Senator Bob Brown voiced his opinion on the matter, and said the following about Australia’s deployment: “The announcement that Australia will be sending 200 more troops to Afghanistan comes hard on the heels of the Bush administration announcing the withdrawal of 3000 troops from the same theatre,” he said. “Without the US withdrawal there would be no Australian deployment. This is John Howard once again using the ADF to meet the Bush administration’s political shortcomings. Our troops should be kept at home.”

“The ADF contribution will be a mixed security and reconstruction taskforce of approximately 200 personnel and will be deployed over a period of two years,” Howard told reporters. The Australian Defence Force (ADF) troops will be deployed from late July and work alongside Dutch soldiers as part of a NATO force. The extra 200 troops will bring the number of ADF personnel to more than 500.

Australia sent 1,550 troops to Afghanistan in 2001, including special forces, to join the U.S.-led strikes against the Taliban regime. Australia’s only fatality in Afghanistan came in February 2002 when a soldier was killed after his vehicle hit a land mine. Violence has intensified in Afghanistan in recent months, particularly in the south and east, with a wave of raids, roadside and suicide bombings killing dozens of people.

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.

Belinda Stronach, Canadian MP for Newmarket-Aurora crossed the floor from the Conservatives to join the Liberals just days before a scheduled confidence vote in the Liberal government. She was immediately rewarded by being appointed to the cabinet as Minister of Human Resources and Skills Development and Minister responsible for Democratic Renewal.

“I’ve been uncomfortable for some time with the direction the Conservative party was taking,” Stronach said. “I regret to say that I do not believe the party leader is truly sensitive to the needs of each part of the country and just how big and complex Canada really is.”

She disagreed with the party on its stance on the federal budget, same-sex marriage, and Conservative leadership’s alliance with the separatist Bloc Québécois to bring down the government.

Two days after Stronach switched parties, the ruling Liberals won a crucial vote for their budget by a single vote. If Stronach had not joined the Liberals and voted for the budget, the government would have fallen, forcing a new federal election.

Over 800 National Health Service staff in Scotland are earning more than £140,000 each year—more than First Minister Alex Salmond. New figures also reveal that 3,000 NHS workers are earning over £100,000. One NHS board alone, NHS Greater Glasgow and Clyde, employs 893 staff earning more than £100,000, and 181 being paid over £140,000.

Jackie Baillie, health spokeswoman for the Labour Party, which uncovered the figures, said they were “astonishing”, and urged health boards to examine if savings can be made by reducing salaries of top earners. “This is a far better option than cutting frontline staff like nurses and midwives. In tough financial times we need to make sure that our focus is on patient care and every penny is spent in the most efficient way.” She further said: “In the current economic climate, it is impossible to justify huge salaries for consultants and senior executives when health boards are planning 4000 job losses this year, including 1500 nurses and midwives.”

Britain’s largest health service industrial union, Unison, questioned the amount of money the NHS was paying. A spokesperson said: “Unison doesn’t begrudge anybody the rate of pay for the job but obviously our membership will be concerned that while they are to face a pay freeze and people delivering frontline services are losing their jobs, there is a cohort of folk who appear to earn more than the most senior politician in the land.”

New currency notes are being introduced in Ghana today. The new currency, to be called the Ghanaian cedi, replaces the previous cedi which has been in circulation since 17 February, 1967.

The Ghanaian cedi will be exchanged at 10,000 old cedis to one new Ghanaian cedi. The exchange rate against the U.S. dollar starts at GH¢0.92 to one U.S. dollar. The new ISO code for the currency is GHS, and the new symbol, GH¢.

The change, which was originally scheduled by the Bank of Ghana to start on July 1, 2007, will instead start on Tuesday July 3, as the original date is Ghana’s Republic Day.

Monday, July 2, was declared a public holiday as the actual Republic Day fell on a Sunday. July 3, is thus the first day that the currency will be available to the public as banks open to the general public. This is because ATMs were shut down over the weekend so that the currencies could be checked and replaced in all of them nationwide. The old and new currencies will be used concurrently until the end of December 2007, when the old currency will cease to be legal tender.

This is the third Ghanaian cedi to be introduced in the country since 1965.

On Wednesday, South African cricketer AB de Villiers announced his retirement from international cricket. The 34-year-old batsman uploaded a video message on Twitter saying it was a “tough decision” and he was “tired”.

De Villiers joined the national team, the Proteas, in 2004, featuring in a test match against England. Since then, the South African talisman has featured in 114 test matches for the Proteas, scoring 8765 runs. He has 22 test centuries to his name, the most recent one coming against Australia in March. South Africa went on to win the test series 3–0.

De Villiers’ batting average is above 50 in both test matches and One Day International (ODI) matches. De Villiers has featured in 228 ODI and 78 Twenty20 (T20) matches as well scoring 9577 and 1672 runs in ODIs and T20s respectively.

In a match against the West Indies at the Wanderers Stadium in Johannesburg on January 18, 2015, De Villiers scored 149 runs from 44 balls. In that match, De Villiers scored the fastest half-century in ODIs, reaching 50 runs from seventeen balls, as well as the fastest century in ODIs, with 100 runs from 31 balls.

Chris Nenzani, the President of Cricket South Africa, said, “AB is one of the all-time greats of South African cricket who has thrilled spectators around the world”.

De Villiers announced his retirement four days after he finished his Indian Premier League season with Royal Challengers Bangalore. In the video statement, De Villiers said, “I have no plans to play overseas, in fact, I hope I can continue to be available for the Titans in domestic cricket.”

With a state by-election coming up in Victoria, Australia, many minor parties and independent candidates will be looking to gain a seat in the Legislative Assembly. Liz Mumby is one of the independents.

“I am a medical sales professional, a wife and mother and a small business owner,” says Mumby, the Division of Altona. “I don’t come from a political background, I live in the real world.” She argues that “we should not limit the debate to public transport issues just because the retiring member was the Minister for Public Transport.”

Wikinews reporter Patrick Gillett held an exclusive email interview with Mrs. Mumby.
