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.

English actress Rachel Weisz thinks that Botox injections should be banned for all actors.

The 39-year-old actress, best known for her roles in the Mummy movie franchise and for her Academy Award-winning portrayal in The Constant Gardener, feels facial Botox injections leave actors less able to convey emotion and that it harms the acting industry as much as steroids harm athletes.

In an interview with UK’s Harper’s Bazaar, coming out next month, Weisz says, “It should be banned for actors, as steroids are for sportsmen,” she claims. “Acting is all about expression; why would you want to iron out a frown?”

Currently living in New York, she also mentions that English women are much less worried about their physical appearance than in the United States. “I love the way girls in London dress,” she claimed. “It’s so different to the American ‘blow-dry and immaculate grooming’ thing.”

Two people in Kenya died earlier today after a five-storeyed building under construction in the town of Kiambu collapsed. Four others were said to have been injured.

The incident occurred in the middle of the night, at 02:30 local time (23:30 UTC), on Sunday morning. The building was only a few metres from another building that collapsed in October of last year, killing thirty people.

The building is reported to have been condemned last year, when the authorities deemed it substandard. Preparations to demolish the building started yesterday, in accordance with a court order that required the building to be destroyed within thirty days.

One of the casualties from the accident was Maina Irungu, aged seventeen; the other hasn’t been identified. People wounded by the collapse were taken to the Kiambu District Hospital. The victims were all people who lived in houses near the collapsed building. Rescue operations are still ongoing, being conducted by the Red Cross, police, and military. Officials also ordered evacuation of two buildings in the vicinity when cracks were spotted on them, according to Capital FM Kenya.

This story in itself is reflective of a major infrastructure problem in Kenya, according to the BBC, China says it will give a US$7 million (£4.4m, €4.9m) grant to help fund infrastructure development projects in Kenya.

2020 Melbourne Lord Mayor candidate Wayne Tseng answered some questions about his campaign for the upcoming election from Wikinews. The Lord Mayor election in the Australian city is scheduled to take place this week.

Tseng runs a firm called eTranslate, which helps software developers to make the software available to the users. In the candidate’s questionnaire, Tseng said eTranslate had led to him working with all three tiers of the government. He previously belonged to the Australian Liberal Party, but has left since then, to run for mayorship as an independent candidate.

Tseng is of Chinese descent, having moved to Australia with his parents from Vietnam. Graduated in Brisbane, Tseng received his PhD in Melbourne and has been living in the city, he told Wikinews. Tseng also formed Chinese Precinct Chamber of Commerce, an organisation responsible for many “community bond building initiatives”, the Lord Mayor candidate told Wikinews.

Tseng discussed his plans for leading Melbourne, recovering from COVID-19, and “Democracy 2.0” to ensure concerns of minorities in the city were also heard. Tseng also focused on the importance of the multi-culture aspect and talked about making Melbourne the capital of the aboriginals. Tseng also explained why he thinks Melbourne is poised to be a world city by 2030.

Tseng’s deputy Lord Mayor candidate Gricol Yang is a Commercial Banker and works for ANZ Banking Group.

Currently, Sally Capp is the Lord Mayor of Melbourne, the Victorian capital. Capp was elected as an interim Lord Mayor in mid-2018 after the former Lord Mayor Robert Doyle resigned from his position after sexual assault allegations. Doyle served as the Lord Mayor of Melbourne for almost a decade since 2008.

The Australian federal treasurer, Peter Costello, has announced a study to compare the Australian taxation system with those of other countries. It will include overall tax levels, as well as indirect tax, income tax and company tax systems. Mr Costello says that the results are intended to inform discussion of the future of the tax system.

“The aim of the study is to provide a public document that compares Australian taxes to those in other countries. This will identify those areas where Australia leads comparable countries and those areas where it lags. It will enable a focus on the most important areas,” Mr Costello said in a media release.

The study will be lead by Mr Richard (Dick) Warburton and Mr Peter Hendy. Mr Warburton is Chairman of Caltex Australia Ltd, and has been Chairman of the Board of Taxation since its inception in September 2000. According to its website, the Board of Taxation is “a non-statutory advisory body charged with contributing a business and broader community perspective to improving the design of taxation laws and their operation.”

The Australian Democrats welcomed the study but warned that nothing would be achieved without serious reform of the tax system.

“The Inquiry announced yesterday by the Treasurer may turn out to be a step in the right direction but will be a pointless exercise if it ends up being simply a ‘desktop’ report,” said Senator Murray, Democrats Tax Spokesperson.

“The problem with Mr Costello’s approach is that in contrast to the approach taken on the GST, the New Tax System, and the Business Tax System, he has seen income tax change to be solely part of the budget process. Across the whole of the political and public policy spectrum, there is strong agreement that reform is needed, not just tax cuts, and that the income tax system needs redesigning, not just fine tuning.”

2008 The 2nd-annual Google Developer Day started its tournament in Pasifico Yokohama, Japan as its first stage. According to Google, this programmer-based event is similar to Google I/O, the largest programming event which is only available in USA and held earlier on May 28 & 29 in San Francisco, California.

Takuya Oikawa, Software Engineer of Google Japan, analyzed the future trend on programming and redefined the “3C”. “There are three key features to drive on the next generation programming, that is, ‘Client’ [user-oriented], ‘Connectivity’, and ‘Cloud Computing‘,” stated Oikawa.

Fumitoshi Ukai, the Software Engineer of Google Japan, has pointed out the importance of Google App Engine, and performed a SWOT analysis using the Sichuan earthquake as an example, and said: “The failure or success of Cloud Computing will be determined by three critical factors – ability of offline computing, language support, and quotas of databases.”

After the Japan Stage, 2008 Google Developer Day will be held in China, Taiwan, Australia, Mexico, and Brazil during the month of June. The Europe Tour of Google Developer Day will kick off from London, England on September 16.

Police in the West Midlands in England today said nearly 200 kilograms worth of drugs with value possibly as great as £30 million (about US$49 million or €36 million) has been seized from a unit in the town of Brownhills. In what an officer described as “one of the largest [seizures] in the force’s 39 year history”, West Midlands Police reported recovering six big cellophane-wrapped cardboard boxes containing cannabis, cocaine, and MDMA (“ecstasy”) in a police raid operation on the Maybrook Industrial Estate in the town on Wednesday.

The seized boxes, which had been loaded onto five freight pallets, contained 120 one-kilogram bags of cannabis, 50 one-kilogram bags of MDMA, and five one-kilogram bricks of cocaine. In a press release, West Midlands Police described what happened after officers found the drugs as they were being unloaded in the operation. “When officers opened the boxes they discovered a deep layer of protective foam chips beneath which the drugs were carefully layered”, the force said. “All the drugs were wrapped in thick plastic bags taped closed with the cannabis vacuum packed to prevent its distinctive pungent aroma from drawing unwanted attention.” Police moved the drugs via forklift truck to a flatbed lorry to remove them.

Detective Sergeant Carl Russell of West Midlands Police’s Force CID said the seizure was the largest he had ever made in the 24 years he has been in West Midlands Police and one of the biggest seizures the force has made since its formation in 1974. “The impact this seizure will have on drug dealing in the region and the UK as a whole cannot be underestimated”, he said. “The drugs had almost certainly been packed to order ready for shipping within Britain but possibly even further afield. Our operation will have a national effect and we are working closely with a range of law enforcement agencies to identify those involved in this crime at whatever level.”

Expert testing on the drugs is ongoing. Estimates described as “conservative” suggest the value of the drugs amounts to £10 million (about US$16.4 million or €12 million), although they could be worth as much as £30 million, subject to purity tests, police said.

Police arrested three men at the unit on suspicion of supplying a controlled drug. The men, a 50-year-old from Brownhills, a 51-year-old from the Norton area of Stoke-on-Trent in Staffordshire, and one aged 53 from Brownhills, have been released on bail as police investigations to “hunt those responsible” continue. West Midlands Police told Wikinews no person has yet been charged in connection with the seizure. Supplying a controlled drug is an imprisonable offence in England, although length of jail sentences vary according to the class and quantity of drugs and the significance of offenders’ roles in committing the crime.

Eight months after a catastrophic earthquake, Wikinews has investigated the devastation caused in February and the reconstruction of Pichilemu, Chile. The February 27 earthquake and a subsequent tsunami completely destroyed Pichilemu’s most coastal street and its oldest villages. Wikinews has also had access to the original design plans of the new kiosks in Pichilemu, and conducted an interview with merchant Alejandro Mella, known locally as the King of the Cochayuyo (“El Rey del Cochayuyo”), who lost his kiosk after the earthquake.

Pichilemu is a coastal city in the O’Higgins Region of Chile, known as one of the “best surfing spots” in South America. Its current Mayor is Roberto Córdova Carreño, who was elected internally by the Councillors of the city in September 2009, after several political controversies that ended with three Mayors being displaced.

The territory of Pichilemu has a surface of 7,491 square kilometers, and comprises at least 24 villages, such as Ciruelos, Rodeíllo and Espinillo (the latter two also severely damaged by the March 11 earthquake). Pichilemu is the most popular beach in O’Higgins Region, and many tourists visit it every summer.

The earthquake took place in what is considered the “last weekend in the summer;” on Saturday, February 27, 2010 at 03:34 local time (06:34 UTC), while almost all Chileans were sleeping. Hours earlier, on Friday, thousands of people had arrived at Pichilemu. “The house moved from side to side. I really thought it was going to fall. It was 3 or 4 minutes long,” Diego Grez, a Chilean student who was in Pichilemu at the time of the quake, told Wikinews in an interview.

A concert was being held at the One Discotheque when the earthquake occurred. It is said that the audience panicked and fled outside the discothèque, and then to the La Cruz Hill. Most tourists fled outside the city right after the earthquake occurred, but many others opted to stay in the La Cruz Hill or the village of Pueblo de Viudas, which are the higher points in the city.

“Pichilemu is the symbolic beach resort in the Sixth Region [of O’Higgins], so it was not strange to even think that [during] the last weekend before the entrance to school, many people would be going to take advantage of it to take a vacation; and that’s what happened,” reported El Rancagüino, the most important newspaper in O’Higgins Region, on February 28.

The only radio broadcasting in the area was Entre Olas, directed by Jorge Nasser, which also helped Pichileminians know what happened in other affected places by the earthquake, as they re-broadcasted the audio of Televisión Nacional de Chile (National Television of Chile). On the day of the earthquake, the station reported that a local police truck had crashed near La Cruz Hill. There was no tsunami warning, and Mayor Córdova was away on holiday when the earthquake struck.

“Those who live in Pichilemu, and those who were visiting it, were surprised by the giant waves that annihilated its beach and reached the city’s square, destroying everything on their way,” reported El Morrocotudo on February 28. “The most tough thing occurred when the firefighters’ alarms sounded twice, and the people in the hill began to yell ‘tsunami!’,” journalist Tania Arce told the newspaper.

The earthquake destroyed one of Pichilemu’s oldest and iconic buildings, the post office, which was demolished in July. The urban centre of Pichilemu was not severely damaged by the earthquake, but its subsequent tsunami caused most of the destruction. The Agustín Ross architecture in the city (three of his buildings are National Monuments of Chile) was damaged. Agustín Ross Balcony was completely destroyed.

According to SHOA, the Hydrographic and Oceanographic Service of the Chilean Navy, the tsunami triggered by the earthquake first reached Pichilemu, at 03:48 (06:48 UTC). A second wave came at 04:15 (07:15 UTC).

Policeman José Arévalo was the only person to warn residents that a tsunami was approaching. Arévalo was patrolling the Las Terrazas beach, when the earthquake occurred. He told El Rancahuaso there were around 25 people in the beach. “Right after the quake, he noticed the sea had shrank around 500 meters inside. He took his megaphone, and shouted people should leave the place instantly.” “The sea is coming out! The sea is coming out!,” he shouted. “The warning was also preceived by nightclubs and pubs surrounding the costanera. Then, the tragedy occurred. The sea destroyed everything on its way,” El Rancahuaso reported. “It all was really quick. Everyone is safe, luckily [..] It’s something unforgettable to me, I’m proud I saved all of those lives,” Arévalo added.

The tsunami destroyed restaurants, hotels, kiosks, the Fishermen Store (Caleta de Pescadores), surf schools, the Agustín Ross Balcony (located right in front of the Las Terrazas beach) and houses near the costanera (the nearest street to the beach), and flooded the building of the Government of Cardenal Caro Province, the boarding school of Pichilemu, the city square (Arturo Prat Square), and the Supermarket El 9.

A local worker, Ricardo Vivanco, also known as “El Gordo” (“The Fat one”), almost was killed by a tsunami, ignoring warnings by the Police and the Fire Bureau. Vivanco was drunk, and went down to the Las Terrazas beach with his friends. The wave washed him away, and was hit on the Agustín Ross Balcony’s wall. His friends recorded a video and uploaded it to YouTube.

It was reported by Radio Entre Olas on February 27, that the tsunami had provoked massive damage in Punta de Lobos, Pichilemu’s most popular beach. The owner of Entre Mar, an hotel and restaurant in that beach, said the tsunami had destroyed all of his buildings there.

The village of Espinillo was badly damaged, and approximately 600 people were made homeless by the earthquake, Teletrece reported on March 16. “We are keeping the government informed, we’re also organized with some churches [sic, religious organizations] that are working voluntarily in Espinillo, Los Boldos, Alto Ramírez […] We thank a lot their work, that is not to give them mediaguas [temporary tenements], but something definitive, but I also think they need resources to do it,” Mayor Córdova said.

On March 11, Chile was hit by a second earthquake, that reached a magnitude of 6.9, and that occurred 40 kilometers southwest of Pichilemu. It occurred at 11:39 local time (14:39 UTC), while the new President Sebastián Piñera was sworn in.

A tsunami warning was issued by SHOA, between Coquimbo and Los Lagos regions. People in Pichilemu fled again to La Cruz Hill. Military authorities assured people in the hill they were going to be safe there, and that it was unlikely a tsunami was going to hit again Chile’s coast. The tsunami warning was lifted at 15:50 local time (18:50 UTC).

People stayed in La Cruz Hill for a longer time than after the previous earthquake, and several activities were made there, such as a concert by Chilean-Brazilian singer Joe Vasconcellos. People were also given food, wood (mostly remains from the destroyed kiosks), and electricity.

“We are here because we fear about our safety. We don’t want it [a possible tsunami] to catch us. We have to settle down here and to accommodate,” Edith Larraín told to Wikinews. Mayor Córdova estimated that at least 2,000 people were staying at La Cruz Hill. Militaries and provincial authorities asked them to leave the hill on March 15, but most refused the deal. People eventually left the hill, due to complaints by the Mayor.

On March 20, in collaboration with the Governor of Cardenal Caro Julio Ibarra, Colonel Raúl Melo, and the Mayor of Litueche Bernardo Cornejo, Mayor of Pichilemu Roberto Córdova announced a “tourism revival campaign” of Pichilemu, promoting the surf practice, whose goal was “to make the city go back to the normality.”

On April 4, the first monument was erected in memory of the earthquake and tsunami victims. The monument was created by local artisans, with rocks from several places of the Cardenal Caro Province. “We wanted to create this monument so we don’t forget it [the earthquake] […] This is the beginning of the reconstruction,” said Julio Ibarra. The monument was placed in front of the beach, near the building of the Cardenal Caro Government. Mayor Roberto Córdova said that “it definitely will help us reconstruct [ourselves] espiritually, [and that] is essential.”

On October 20, with the help of the Government, SERCOTEC (Technical Cooperation Service, Servicio de Cooperación Técnica) and FOSIS (Solidarity and Social Investment, Fondo de Solidaridad e Inversión Social), the Fishermen Store (Caleta de Pescadores) began to be reconstructed. Caleta de Pescadores is administered by the Independent Labour Union of Fishermen of Pichilemu (Sindicato de Trabajo Independientes de Pescadores Artesanales), which has twenty-three members.

“The Government of President Sebastián Piñera has been worried about the fishing area, carrying out several actions in help of them, after all that they’ve suffered after the earthquake and tsunami that hit them […] This area is working normally again,” Governor Ibarra said.

On October 6, the Municipality of Pichilemu published the design of kiosks that were going to be constructed, as replacement of those destroyed by the earthquake. As of October 23, four kiosks have been constructed in Pichilemu, specifically on Las Terrazas beach, and two more are being constructed. According to Mauricio Grez, a construction engineer, the construction of one kiosk would cost up to US$ 2,500 (CLP 1,000,000).

Alejandro Mella, locally known as “el Rey del Cochayuyo” (“the King of the Cochayuyo”), is a merchant of Pichilemu, who promotes the cochayuyo (durvillaea antarctica), and lost his kiosk after the February earthquake and tsunami. “I was given my [former] kiosk by the Mayor Orlando Cornejo, back in 1993. It was right in front of us [in front of Las Terrazas beach, near “the grotto of the Virgin”], and was made smithereens by the tsunami,” he told Wikinews.

“I have always worked on selling cochayuyo here, and the terrain where my kiosk was located before has been disputed by private people, and the municipality approved that. I talked with the Mayor and he said ‘I don’t know what’s going on the beach’; that left me perplexed. […] I like the new design of the kiosks, they are larger, and we can do more things with it, but they are way too expensive,” he added. Mr. Mella also gave Wikinews a sample of his work as “the King of the Cochayuyo”, an essay called “El cochayuyo es una mina repleta de nutrientes y sales minerales” (“Cochayuyo is a mine full of nutrients and mineral salts”, pictured below), which he sells for 200 Chilean pesos (0.41 US$), and that contains “tips and information about the plant, and some recipes.”
