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.

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.

Infections and complications from preterm birth cause more than half of all neonatal deaths, and very low birth weight babies are particularly vulnerable.

Preterm babies have immature skin that lacks a protective film called vernix that has antimicrobial properties.

In some countries, such as India, newborns are routinely massaged with mustard oil.

But mustard oil, says Gary Darmstadt of John Hopkins University in Baltimore, Maryland, can delay recovery of the skin barrier and have a toxic effect on skin.

Seeking an alternative low-cost product, Darmstadt and colleagues experimented with sunflower oil and an ointment called Aquaphor that comprises petrolatum, mineral oil, mineral wax and lanolin.

The researchers tested the treatments on 497 newborns (72 hours old or less) and preterm babies (less than 33 weeks gestation) between 1998 and 2003 in Bangladesh.

They applied the treatments to the entire body besides the scalp and face three times daily for the first 14 days and then twice daily until discharge.

Babies treated with sunflower oil were found 41% less likely to develop infections than controls.

“Evidence is emerging that the skin is much more important as a barrier to infection than previously recognized, particularly in preterm infants whose skin is underdeveloped,” says Darmstadt. “The good news is that treatment is available to strengthen the function of the skin as a barrier in these vulnerable newborns.”

The California Controller’s office reports that eleven state agencies have given US$13.3 million in pay and travel advances that have not been collected.

Governor Jerry Brown issued an executive order to recover uncollected loans by the agencies. A press release from the governor’s office states, “The Governor’s Executive Order seeks to recover taxpayer dollars by directing state agencies and departments to clear salary and travel advances within 30 days through an expense claim.” Any outstanding balance will be deducted from employees’ paychecks under the governor’s order after the 30 days.

Under California state law, state employees are permitted to receive advances for hardship, travel, and other circumstances. These advances cannot be collected by agencies after three years without the employee’s consent.

State Controller John Chiang said in a statement, “The state’s poor debt collection and accounting practices are fleecing public coffers at a time when vital public programs are being decimated by unprecedented budget cuts.” Chiang’s office expects there will be more money unaccounted for, including some from the California Highway Patrol (CHP). California state law mandates that anyone convicted of driving under the influence of alcohol is required to pay for the investigation. The CHP has not collected this money.

The California Department of Transportation, also called Caltrans, has the largest debt of the eleven agencies: $3.2 million. Cal Fire, or the California Department of Forestry and Fire Protection, “had an outstanding balance of $1.44 million as of June 30, 2008. An overwhelming portion of that balance was related to employee salary and travel advances,” according to a controller’s office audit.

Chiang’s office had informed former California governor Arnold Schwarzenegger there were outstanding debts, but Schwarzenegger’s administration did not take action.

All eleven agencies have agreed to hand over any delinquent accounts to the controller’s office, who will collect these debts.

Partygaming Plc, the worlds largest online poker company, has announced that it intends to float on the London Stock Exchange by the end of this month. Although it has not yet set a price, analysts in The City are speculating that the flotation could value the firm at up to STG£5bn. Such a valuation would make the flotation the largest in four years.

The Gibraltar-based company, which owns the Partypoker brand, intends to sell 23% of the company in the flotation. If the company’s initial public offering is successful, the firm will enter the FTSE 100 Index (the top 100 firms on the exchange by value). Its value would be greater than that of both British Airways and Boots.

Partygaming Plc was founded in 1997 by Anurag Dikshit and has since grown at a huge rate – doubling profits in the past year alone to STG£371m. At peak times it attracts 70,000 simultaneous players.

A 14-year-old boy has been killed in an accident involving a quad bike in County Londonderry, Northern Ireland. The boy has been identified as Paddy McErlean, who crashed near his house in the town of Maghera.

What is believed to have happened is that Paddy was travelling on an all-terrain vehicle with a 16-year-old boy along a rural road at around 2200 GMT on Thursday when the vehicle smashed into a post, the boys were then thrown from the road. The 16-year-old boy is critically injured and as of yet has not been identified.

Ann Scott, who is the head teacher in St. Patrick’s College, which is the high school that Paddy attended, said: “This tragic accident really has brought a profound sense of loss to the school. The loss of Paddy, who was only 14, has just shocked everybody at the college. He really contributed a lot to the school, he was full of life, he was such a lovely young lad, very popular with the staff and pupils and we will really miss him so terribly.”
