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.

Craigslist.com, a popular free online classifieds site, has been sued for hosting discriminatory housing ads by the Chicago Lawyers’ Committee for Civil Rights Under Law Inc., a fair housing group.

The housing ads cited as objectionable included such statements as “NO MINORITIES,” “Requirements: Clean Godly Christian Male,” and “Only Muslims apply.”

Stephen Libowsky, a lawyer for the housing group, said “Our goal is to have the Internet places like Craigslist treated no differently than newspapers and other media who have traditionally been posting real estate advertisements. All of the gains are going to get lost if the same rules don’t apply.”

Craigslist CEO Jim Buckmaster conceded “We admit that one or two postings per 100,000 are discriminatory” but explained that Craiglist’s 19 employees could not physically screen the 8 million new ads posted each month. He continued, “Instead, we’ve done something much more powerful and effective, in providing our users with a flagging system whereby problematic ads are promptly removed by users themselves.” Buckmaster claimed the “NO MINORITIES” ad was removed within two hours.

Buckmaster wrote on the site that, “Though well-intentioned, this lawsuit misguidedly demands that we regress to primitive, mistake-prone, and wholly inadequate methods, methods which would actually be less effective in catching discriminatory ads than what we have in place currently, and which would vastly reduce the number of legitimate non-discriminatory ads that the site could process.”

He continued, “Ironically, if this lawsuit were to succeed the net effect would be to deal a double blow to civil rights – by significantly reducing access to equal opportunity housing, and by undercutting our fundamental free speech rights – thereby doing a great disservice to the very persons these lawyers purport to represent.”

Buckmaster also said “It is our understanding that the law is very clear to the effect that sites like Craigslist cannot be held legally liable for the content of postings submitted by end users.” This claim appears based upon Section 230 of the Communications Decency Act which states that “No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.”

Under section 7b of the web site’s Terms of Service agreement, users are not allowed to post an ad “that violates the Fair Housing Act by stating, in any notice or ad for the sale or rental of any dwelling, a discriminatory preference based on race, color, national origin, religion, sex, familial status or handicap (or violates any state or local law prohibiting discrimination on the basis of these or other characteristics)”.

Children who spend more time playing with other children are less likely to end up getting childhood cancers, a UK study published today in the British Medical Journal has found. The finding supports the researchers’ theory that reduced exposure to common infections in the first year of life increases the risk of developing acute lymphoblastic leukaemia (ALL).

A total of nearly 10,000 children took part in the study, located in 10 regions across the UK. Amount of time spent in daycare and social activity, during the first year of life, were used to gauge the level of exposure of the infants to common infections such as cold and flu.

Day care in the first year of life for at least two days a week, with at least three other kids, halved a child’s chance of contracting ALL. Those who were rated in the category “any social activity” still had an improvement over the children rated as “no social activity”: they had about 3/4 the chance of getting the disease.

The study describes that effect was “more striking” for acute lymphoblastic leukaemia — a cancer affecting blood and the immune system — than it was for the set of all other cancers. Increasing levels of activity saw decreasing chances of childhood cancers, when compared against children who during their first year had no regular social activity outside the home.

Theories have been around since the 1940s that childhood exposure to infection was related to the development of childhood leukaemia — one, like the working theory of the UK study, said that lack of immune challenge was a factor, another that leukaemia developed as a delayed result of some type of infection.

The research was conducted by the Institute of Cancer Research in London and in Sutton, London School of Hygiene and Tropical Medicine, University of York, Christie Hospital and Central Manchester and Manchester Children’s University Hospitals NHS Trusts, and the University of Edinburgh.

After more than two years, much controversy remains in the case of a British student who was killed in the central Italian university town of Perugia. Two separate trials have been held for the three suspects. All three have been convicted and are in prison serving sentences of 30, 26 and 25 years. But all three continue to proclaim their innocence.

The most well-known of the three young people convicted of the murder of Meredith Kercher in November 2007 is American-born Amanda Knox.

The British tabloid newspapers immediately described Knox as a she-devil and man-eater. A week ago, 22-year-old Knox and her former Italian boyfriend Raffaele Sollecito were convicted to 26 and 25 years in prison respectively after a trial that lasted 11 months. The prosecution had requested life imprisonment.

The third suspect, Rudy Guede, from the Ivory Coast, had previously been convicted of 30 years in prison in a fast-track trial. Nick Pisa is a British tabloid journalist who has been covering the story since Kercher’s dead body was found.

“In general I think people were expecting this verdict. It was certainly one that has been anticipated by both the Italian media and the Italian public,” Pisa said. “I think the only people who were surprised were perhaps the Anglo-Saxon press because in the face of the evidence that was presented in court it’s very, very unlikely that this case would have been found guilty in another court.”

No one argues that there is no evidence that puts Knox at the scene of the crime. But the prosecution has said there is plenty of circumstantial evidence that she was involved. He said Knox changed her version of the story many times and also unjustly accused a Congolese bar owner, for whom she had worked.

Knox’s mother, Edda Mellas, insists her daughter is innocent, that she was not home the night Kercher was killed and adds her daughter has been in prison for more than two years without reason.

“She’s devastated, she’s scared that she’s going to be stuck in jail,” Mellas said. “She’s confused… I don’t think she even believed that courts find innocent people guilty of crimes they didn’t commit and especially in this case where there was no evidence.”

Mellas paints a very different picture of her daughter than the one presented by the prosecution and media.

“Amanda’s a great young woman,” Mellas said. “She’s very bright. She’s athletic. She’s kind. She has really, really good friends. She’s just a normal college kid.”

Knox’s family members say they will fight on and appeal the court’s decision. They say the verdict, based on the evidence presented, was wrong. Nick Pisa agrees that the appeal could make the difference for Knox.

“It does appear that the evidence that convicted her was very, very flimsy and I think once they examine this DNA evidence again – let’s remember there was the request for an independent review that was ruled out by the judge,” Pisa said. “And I think that’s probably one of the first things that a new judge will ask for when he comes to review this case.”

By early March the court will provide a written document outlining the reasons behind the verdict. An appeal by Knox’s defense lawyers will be deposited soon after that. In the meantime Knox will have spent her third Christmas in an Italian jail as she awaits for a hearing date to be set, which is unlikely to be before October 2010.

Yesterday, at least seven people including Aden, Yemen governor Jaafar Mohammed Saad died in a car bomb attack on their convoy in the city of Aden, according to local officials. An online claim of responsibility on behalf of militant group ISIS called Saad a “tyrant”.

An online post purportedly from the group claimed they detonated the bomb as Saad’s convoy passed where the car was parked. The post shared photos purporting to show Saad’s vehicle passing the parked car, and the following explosion.

People as much as 10km away reported hearing the explosion, and medics said it left victims’ bodies unrecognizable. Photos supposedly of the attack showed a burning, wrecked car. Aden’s Jumhoriya Hospital treated the victims.

The online statement threatened to “chop off” the “rotten heads” of Yemen’s “infidels”, and said more attacks are coming.

Iran-backed Houthi rebels, who follow Shia Islam, have taken over Yemen’s capital of Sanaa. Until just recently, President Abed Rabbo Mansour Hadi’s government operated for several months in Saudi Arabia, which has led a coalition involving air strikes against the rebels.

Yemeni fatalities in ISIS-claimed bombings this year number reportedly around 159. Yemeni fatalities since March, when Saudi Arabia’s pro-Hadi airstrikes began, number at least 5,700 according to the United Nations.
