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.

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ^{((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????.} He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ^{((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.}

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.

Witnesses say a truck was idling near the scene of an explosion at a Texas refinery which killed 15 and injured over 100 others on March 23, according to U.S. Chemical Safety and Hazard Investigation Manager Bill Hoyle.

“Witnesses saw vapor in the area of the truck and observed the engine begin to rev up and race,” Hoyle’s statement said. “This behavior by a diesel engine indicates the presence of a flammable atmosphere entering the air intake. A driver reported trying to shut off the engine but was unable to do so.” Hoyle’s statement continued, “There are multiple possible sources of ignition in an operating refinery unit and we have made no determination about the ignition source at this time.”

The investigation has been delayed by BP and Occupational Safety & Health Administration officials, who are trying to preserve evidence at the site for their investigation. They are also concerned about further injuries from hazards left over from the explosion, such as falling debris and unstable structures. The Environmental Protection Agency also detected benzene in the atmosphere over the plant, which was treated with a layer of foam.

BP has retained control of the plant since the March 23 accident. Police arrived quickly the day of the explosion, but left after the initial emergency was over.

“Our officers could respond over there, but they don’t have a clue,” Texas City police Sgt. Curtis Pope told the Houston Chronicle. “The fact is they have chemical and equipment hazards. We don’t know the chemicals.”

Lai Changxing, dubbed the Bandit King, has been given a life sentence for years of smuggling and corruption that added up to billions of US dollars or Pounds sterling. The Chinese court described the values as “massive”.

Lai smuggled goods worth more than £2 billion into Xiamen, bypassing more than £1 billion in import duty. He paid 64 local officials a total of almost £4 million in bribes, giving him effective control of the city from 1995 to 1999. He fled China after becoming a wanted man in 1999 and went to Canada via Hong Kong; the following year, Premier Zhu Rongji said “If Lai was executed three times over, it would not be too much”.

As head of the Yuanhua Group, Lai smuggled in cars, chemicals, oil, cigarettes, and other goods. He distributed bundles of cash to the poor, owned and played for his local football team, built stadia, owned a bulletproof Mercedes that once belonged to President Jiang Zemin, and attempted to construct a tower that would have been the nation’s tallest building. He attained local popularity for funding construction projects including schools, hundreds of tower blocks, and the local airport.

As well as money, officials were offered alcohol and prostitutes. Many were offered time at Lai’s seven-storey brothel, the Red Mansion, and feasted at a replica of the Forbidden City.

State TV has broadcast footage depicting a banquet table with a tiger skin laid upon it, cars given to officials, a young woman alleged to have been donated as a lover, and a sackful of gold rings. The case’s prominence was such that Liu Liying, boss of the national Central Discipline Inspection Committee, took charge of bringing Lai down.

Subsequent investigations have examined more than 1,000 suspects with police at one stage turning over an entire hotel to the probe, filling rooms with suspects. National newspaper The People’s Daily has suggested it is the most serious economic crime in modern Chinese history. He was the nation’s top car importer and one of the main traders in oil and imported cigarettes.

Hundreds of officials have been convicted and it is estimated hundreds more remain. Fellow life-sentence prisoners from the case include the city’s deputy mayor and its head of customs. The nation’s former vice-minister for security, Li Jizhou, has a suspended death sentence. Other suspects have killed themselves.

Upon his escape from the nation Lai became China’s most-wanted fugitive. Twelve years of negotiations ended with a Chinese promise Lai would be spared the death penalty, and Canada extradited him last year. Numerous lower-ranking members of Lai’s empire have already been given life imprisonment or death sentences. With execution off the table, the court gave Lai the highest sentence possible: in addition to the life term, he received fifteen years for bribery and had all his possessions confiscated.

The court justified the “double sentence” on the grounds “the sums involved are unusually large, and the details are extraordinarily serious”. “The crimes involve massive sums and particularly serious circumstances,” court officials told Xinhua. Lai had denied corruption at his trial, although he accepted exploiting loopholes to avoid import duty.

“I don’t have a good family background,” Lai said previously in a press interview. “I have to do things step by step by myself. That’s how people came to respect me. I never fussed about big money.” Lai was born as one of eight siblings in the midst of famine.

A review this week by Wikinews of US Consumer Financial Protection Bureau (CFPB) complaints about student loans in the United States shows Sallie Mae leads all lending institutions in complaints. Of the 4,851 complaints dating back to March 2012 when the CFPB first began collecting student loan data, 2,262 or 46.6% of all complaints were about the lender. US Federal Reserve data from 2010/2011 shows Sallie Mae is the nation’s largest student loan lender, responsible for 25% of the market

The other major lenders in this space include Wells Fargo, JP Morgan Chase, PNC, and Discover. In complaints, AES/PHEAA came in second with 546, or 11.3% of all complaints. Wells Fargo, Citibank and JPMorgan Chase each had between 5% and 7.5% of all complaints, totaling 918 complaints between them. 78 other lending institutions round out the list of organizations with complaints filed against them for student loans.

Few of the complaints originate from people with problems with federal student loans. Less than 1%, 35 total, are for these types of loans, with Sallie Mae accounting for the bulk of complaints with 17 total. 14 other lending institutions have 3 or fewer complaints. For non-federal student loans, Sallie Mae is still the leader for complaints, with 2245 or 46.6% of all non-federal student loan complaints.

The Consumer Financial Protection Bureau sorts complaints into three issues: Problems when you are unable to pay, Repaying your loan, and Getting a loan. None of the federal loans had complaints about getting a loan. For non-federal loans, 65.5% of the 4,816 complaints related to loan repayment. Sallie Mae led in total complaints in this category with 1467. They were followed by AES/PHEAA with 356, Wells Fargo with 231, Citibank with 201, Discover with 158, JPMorgan Chase with 154, ACS Education Services with 143, and KeyBank NA with 116. CFPB says loan repayment issues include a basket of claim types including “fees, billing, deferment, forbearance, fraud, and credit reporting.” Problems when you are unable pay accounts for 30.8% of the complaints. Sallie Mae had 698 complaints. They were followed by AES/PHEAA with 181, JPMorgan Chase with 106, Wells Fargo with 104, Citibank with 70, and KeyBank NA with 58. Many of the complaints are, according to the CFPB, because borrowers have difficulty getting deferrments on loan repayment as a result of being unable to find employment.

The total complaints against Sallie Mae for September of this year is 2 fewer than the same time last year. The company’s performance this year compared to last year has been mixed. March and June numbers were down over 150 complaints from the same month a year before. April, May, July and August all saw increases of 17–43. Of the top six lenders by volume of complaints, only AES/PHEAA and Citibank saw drops every month between March and September from the total volume in the previous year. Wells Fargo had a gain of 1 in August and 6 in May from the previous year. JPMorgan Chase had a difference of 0 from the same month last year for April, 3 more this year for May, and 4 more for August. Discover saw an increase every month from the same period last year except for September. When the total complaints differences from year to year for March to September are counted, this year has 571 fewer complaints against the top six lenders.

Most, 1470, of the complaints against Sallie Mae were closed with explanations. 10.2% were closed with monetary relief. 7.7% were closed with non-monetary relief. 2.1% were closed with relief and 12.1% were closed without relief. AES/PHEAA’s complaint closure picture was much different. 40.1% of AES/PHEAA’s 546 complaints were closed with non-monetary relief, 35.3% were closed with explanations and 21.2% were closed without relief. Of the eight lending institutions with 100 or more complaints filed against them, Discover was the institution most likely to result in a closure with monetary relief with 12.9% of all their closures ending this way. Citibank was the institution with the highest percentage of closures ending with no relief at 26.0%.

Complaints over student loan lenders were geographically distributed, coming from 3,447 different zip codes. The largest cluster of complaints is for 20001, a Washington D.C. zip code with 10 complaints originating from there. 07950, the zip code for Morris Plains, New Jersey, and 37013, the zip code for Antioch, Tennessee, each had 8 complaints originating from them. Zip codes for Patchogue, New York; Philadelphia, Pennsylvania; Washington D.C.; and Arlington, Virginia each had 7 complaints originating from them. By volume of complaints by state, New York led with 497, with California second with 467, Pennsylvania third with 303, Florida fourth with 288 and Ohio fifth with 219 complaints. US Territories largely occupied the bottom spots. The Northern Marianas Islands, with a population of around 50,000, had 1 complaint. The U.S. Armed Forces – Pacific had 3. North Dakota and U.S. Armed Forces – Europe had 5 complaints each. South Dakota had 7. Wyoming had 8. Puerto Rico and Alaska had 9 each. Rounding out the bottom five states by volume of complaints, Mississippi had 11.

With the possibility of a United States government federal shutdown looming on October 1, student loans may be impacted because of potential for an automatic increase in interest rates.

In a new setback to the Thai government’s efforts to ease mounting political tensions, protest leaders escaped from their hotel Friday after security forces arrived to arrest them.

One, Arisman Pongruangrong, climbed down three floors using a rope, and was rushed away by supporters thronging the building. The police say Arisman led recent rallies at the national parliament, the election commission, and satellite transmission bases.

Officials earlier Friday said the government is preparing to arrest people linked to violent clashes with security forces last Saturday.

Deputy Prime Minister Suthep Thaugsuban, Thai security chief, announced the raid on the hotel as it was unfolding, saying that a Special Forces unit had closed in around a downtown Bangkok hotel.

“As I am speaking, the government’s special team is surrounding the SC Park Hotel, where we have learned that there are terrorists and some of their leaders hiding,” Suthep said.

A spokesman for the governing Democrat Party, Baranuj Smuthararaks, says arrest warrants have been issued for those suspected of being involved in the violence. Some of the suspects have been identified from photos taken during the clashes.

“Right now the government’s focusing on issuing warrants for acts of terrorism by the people who fortunately have been captured in action [in photos] by both the local and international media,” he said.

According to the New York Times, as many as five protest leaders had been staying at the same hotel as Pongruangrong. Those leaders later appeared together at a protest rally in Bangkok.

“I would like to thank all of the people who saved me,” Arisman said. “You have saved democracy.”The government says armed men infiltrated protester ranks Saturday and fired on troops trying to disperse a rally. Five soldiers and 19 protesters died during the clashes.

Thailand is facing its most severe political crisis in almost 20 years. The anti-government movement, led by the United Democratic Front against Dictatorship or UDD, demands that the government step down and call fresh elections.

UDD supporters, known as red shirts, have held protests in Bangkok for more than a month.

The UDD largely supports former Prime Minister Thaksin Shinawatra, who was ousted in a coup in 2006 and remains overseas to avoid a jail sentence for corruption. Mr. Thaksin has strong support among the rural and urban poor, as well among some sections of the army and police.

Some parties in the governing coalition want to set a clear time frame for elections to ease tensions. But the government says it will only call elections once the political situation has cooled.
