U.S. Defence Secretary Robert Gates warned that limiting funding for the United States efforts in Iraq could lead to more bloodshed in the Middle Eastern country. In an interview with radio talk show host Laura Ingraham, he said it might even lead to ethnic cleansing in Bahgdad and elsewhere in Iraq.

Gates’ comment followed a proposal from Senate Majority Leader Harry Reid to end most spending on the Iraq war in 2008, limiting it to targeted operations against al Qaeda, training for Iraqi troops and U.S. force protection.

Sec. Gates also said that the duration of the troop increase is not clear and that evaluating whether the Administration’s new strategy was working will have to wait till mid-summer. The Army general charged with day-to-day operations has suggested that the increased deployment may extend to early next year.

Major British charity Comic Relief has invested money in arms, alcohol and tobacco firms, according to a BBC Panorama investigation to be broadcast this evening.

The probe discovered evidence of hundreds of thousands of pounds going towards shares in weapons firms like BAE Systems and alcohol company Diageo. It is also alleged to have pledged upwards of £3 million into tobacco firms.

Ethical fund manager Helen Wildsmith told Panorama: “If people who’ve been giving them money, after watching the television, next year think twice and don’t give that money, because they’re concerned about their investment policy, then that could be argued to be a breach of fiduciary duty. They’re risking their reputation, and a charity’s reputation is very precious.”

Comic Relief was founded in 1985, and since then has taken in nearly £1 billion in donations. It funds charitable organisations in the United Kingdom as well as overseas. It uses a range of managed funds, which invests the money in the charity’s name – including on the stock market – in order to maximise return.

A spokesperson for the charity told the British newspaper The Daily Telegraph: “We put the money into large managed funds, as many other leading charities and pension funds do. On balance, we believe this is the approach that will deliver the greatest benefits to the most vulnerable people.”

The controversial investments were made between 2007 and 2009, Panorama explains. Peter Bennett-Jones, former chair of the company, defended the investments in a post on The Guardian’s website.

He said: “The Charity Commission guidance is quite clear that trustees must invest for the best possible financial return, while taking a level of risk appropriate for money in their care. They should only adopt an ethical investment approach with specific justification and not on the grounds of individual moral views. This sounds counterintuitive, but it is the law.”

Recently, Finnish open-source video game developer Perttu Ahola discussed Minetest, his “longest ever project”, with Wikinews.

Started in October 2010, Minetest was an attempt by Ahola to create a sandbox game similar to Minecraft. Minecraft is a multi-platform commercial game, which was in alpha version when Ahola challenged himself to create something similar to it from scratch, he told Wikinews.

Minetest is an open-source game, which is free for anyone to download and play. It is written in the C++ programming language, and the source code is available on code-hosting site GitHub. According to Ahola, Minetest attempts to run on older hardware, with limited graphics, but to be accessible to more people: those who have outdated technology, and making it available for no cost. Minecraft, on the other hand, is a paid game, currently costing USD 26.95 for its computer version. Minecraft is currently owned by Microsoft, and performs poorly on older hardware.

A correspondent from French Wikinews contacted Perttu Ahola via Internet Relay Chat a few weeks ago, discussing Minecraft. This interview is built on top of the previous interview, as we take a deeper dive into knowing more about this free game which is about to turn ten years old in a few months.

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.

A paste containing synthetic tooth enamel can seal small cavities without drilling. Kazue Yamagishi and colleagues at the FAP Dental Institute in Tokyo say that the paste can repair small cavities in 15 minutes.

Currently, fillers don’t stick to such small cavities so dentists must drill bigger holes. Hydroxyapatite crystals, of which natural enamel is made, bond with teeth to repair tiny areas of damage.

Yamagishi and colleagues have tested their paste on a lower premolar tooth that showed early signs of decay. They found that the synthetic enamel merged with the natural enamel. The synthetic enamel also appears to make teeth stronger which will improve resistance to future decay. As with drilling, however, there is still the potential for pain: The paste is strongly acidic to encourage crystal growth and causes inflammation if it touches the gums.

The paste is reported in the journal Nature.

Zach Scruggs, a lawyer for United States Senator Trent Lott, says that State Farm Insurance Company is destroying records related to claims for damage from Hurricane Katrina.

The records allegedly contain information saying that State Farm fraudulently denied insurance claims made by its policy holders, including Lott, that had homes there were damaged or destroyed when Hurricane Katrina came ashore on the Gulf Coast.

Scruggs said that Lott has “good faith belief” that many employees of the insurance company in Biloxi, Mississippi are destroying engineer’s reports that were inconclusive as to whether or not water or wind was the main cause of damage to the buildings affected by the hurricane.

Lott is among thousands of home and/or business owners who had their property damaged or destroyed during the hurricane and had their claims denied because State Farm claimed that their policies don’t cover damage caused by floods or water that was driven by the wind.

State Farm has not issued a statement on the matter so far.
