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.

The discovery of the presence of airborne asbestos in a middle school in Montclair, New Jersey Friday prompted the evacuation of over 200 students from the school and the school’s closure. Renaissance Middle School, part of the Montclair Public Schools in New Jersey, was closed Monday and remains closed Tuesday while undergoing asbestos testing and cleaning.

According to a letter sent home to parents by the Superintendent’s Office of Montclair Public Schools on Friday, “plaster may have been disturbed” during construction on new fire doors at the Renaissance School building on Thursday.

An inspection arranged by the school district indicated asbestos was present in the plaster, and a subsequent inspection performed by asbestos consultant Detail Associates revealed “a level of airborne asbestos fibers that exceeded the acceptable range” in the third floor hallway of the school. Montclair Public Schools business administrator Dana Sullivan told The Star-Ledger that testing conducted on March 31 revealed the presence of asbestos in a brown undercoating of plaster at the Renaissance School building.

The affected area was sealed off, and some students were moved to other areas of the building while others were moved to off-site locations. District Public Information Officer Laura Federico told The Montclair Times that sixth and seventh graders were transported to Hillside Elementary School, and eighth graders were bussed to Montclair High School. “The safety of our students and staff is always our first concern,” said Federico.

According to The Montclair Times, Detail Associates conducted a cleaning protocol at the school on Saturday and tested the building to make sure it did not contain unacceptable levels of asbestos fibers. The letter sent to parents Friday by the Superintendent’s Office said that Detail Associates had told the district that the building would be “cleaned, tested and cleared for occupancy by Monday morning”. The school remained closed Monday, and a meeting was held between parents and school district officials. A Parent-Teacher Association meeting is planned for Wednesday night.

The Star-Ledger reported that the ongoing asbestos cleanup of the school is being supervised by the state Department of Environmental Protection. At the meeting Monday morning between parents and school district officials, parents demanded that the inside of lockers be included as part of the asbestos cleanup. This additional step in the asbestos inspection process prompted the school’s closure Tuesday. A Monday statement by the Business Office of Montclair Public Schools said that the Renaissance School would remain closed Tuesday for sixth and seventh grade students “so that an extensive cleanup and additional asbestos testing can be completed”. Eighth grade students did not have classes scheduled as a trip to Washington, D.C. had previously been planned; the school trip is unaffected by the recent asbestos incident.

Steve Jaraczewski of Detail Associates was present at the district meeting Monday, and said that one of four test samples taken at the school was positive for the presence of airborne asbestos at over six times acceptable levels. Jaraczewski was critical of the asbestos management plan provided by Roman Catholic Archdiocese of Newark, which owns the school’s building and leases it to Montclair Public Schools.

Jaraczewski said that the state Department of Environmental Protection has required asbestos management plans since 1988, but that the company that drafted the asbestos plan for the Archdiocese of Newark is out of business. Representative for the archdiocese Jim Goodness emphasized that the building would be back open for classes soon. “The kids will be able to go back to school soon, and that’s the important part,” said Goodness.

Exposure to airborne asbestos can lead to mesothelioma, a cancer which develops in the sac surrounding the lungs and chest cavity, abdominal cavity, or the sac surrounding the heart. Exposure to disturbed asbestos fibers can also lead to lung scarring, a condition called asbestosis, and lung cancer. Patients with malignant mesothelioma generally do not have positive outcomes, and once diagnosed have six months to a year to live.

Toyota announced on Friday that it will recall around 17,000 Lexus vehicles in response to risks of the fuel tank in the cars leaking after a collision.

The Lexus HS 250h model was subjected to the recall following a US National Highway Traffic Safety Administration (NHTSA) investigation. Despite previously passing Toyota safety inspections, the conclusions of an NHTSA sub-contracted investigator were that; when the vehicles in question collided with an object at more than fifty-miles-per hour, more than 142 grams of fuel, the maximum allowed by US law, leaked from the crashed car.

According to Toyota, further tests did not show any additional failure of the fuel tank.

In response to the findings, Toyota issued a recall of all affected vehicles, since the company had no solution immediately available. The recall includes 13,000 cars already sold, as well as another 4,000 still at dealerships.

Toyota says it plans to conduct further tests to determine the cause of the leak. A Toyota spokesman, Brian Lyons, said that the company was “still working to determine what the root cause of the condition is.” It’s still unclear when exactly the recall will take place, or when dealerships will be allowed to sell this model again. Lyons said that Toyota is “working feverishly to get this resolved as soon as possible.”

Toyota isn’t aware of any accidents stemming from the leaking fuel tank in the affected vehicles, first introduced in the summer of 2009.

The French capital Paris has seen a second night of violence by demonstrators, who have blamed police for the death of a motorcyclist on Sunday.

On Sunday night youths in the eastern suburb of Bagnolet, set 29 vehicles alight and threw stones and petrol bombs at police. Monday night was “relatively calm” according to Samira Amrouche, spokeswoman for the regional administration, the authorities having depolyed 40 vans of riot police only 8 vehicles were burnt.

The motorcyclist, a pizza deliveryman, was killed when he fled police attempting to examine his documents, dying when he was struck by a pursuing police vehicle according to the youths,however in the police version his death was a result of him crashing into barriers.

The current violence has echoes of the unrest in 2005, with again dissaffected youths of Arab and black descent venting their anger and frustration.

The leaders of the North American Free Trade Agreement (NAFTA) met in Guadalajara, Mexico on Sunday and Monday. The leaders of the three countries (Barack Obama of the United States, Felipe Calderón of Mexico, and Stephen Harper of Canada) promised to work together on swine flu, organised crime and green issues.

Despite disputes in a number of areas remaining unresolved, the three leaders succeeded in presenting an amiable Three Amigos image. The three leaders expressed solidarity, and an understanding of each others position.

The unresolved issues include the buy American clauses in the US stimulus package, tit for tat reprisals by the Mexican authorities over Canadian visa restrictions on Mexican travellers, and the US ban on Mexican trucks from crossing the border.

Risking the ire of human rights activists back home President Obama expressed support for President Calderón’s war against drugs saying he had “great confidence” in the Mexican authorities.

Mexican Federal Police (Policía Federal) have foiled an alleged plot to assasinate the President of Mexico Felipe Calderón. Acting on intelligence gathered over a year the Federal Police arrested five drug cartel members on Sunday and publicly paraded their captives and a number of weapons ,including automatic rifles, on Monday. Speaking during a summit of North American leaders Calderón played down the threats on his life, saying that the cartels are being destroyed by his policies.

Some 11000 have died since President Calderón’s took office in 2006 and made the war on drugs a cornerstone of his administration.

Aung San Suu Kyi has been sentenced by a court in Burma to a further three years of house arrest for violating the terms of her previous sentence. However her sentence was immediately commuted to 18 months on the orders of Burmese head of state Senior-General Than Shwe out of respect for her father General Aung San and out of a desire for “national reconciliation”.

The period of her arrest will prevent Aung San Suu Kyi from participating in the general elections scheduled for 2010. The sentence was immediately condemned by Western leaders, and breaking from their usual silence, the Association of South East Asian Nations (ASEAN) through its current chair Thailand issued a statement expressing disappointment. The ASEAN statement and talk of further European Union and United States sanctions are unlikely to have any impact on Southeast Asian country given the support of India and China.

The Chinese issued a statement calling for the world to respect Burmese sovereignty and laws, and is seen as an indication that China, a veto power will not support any United Nations actions.

John Yettaw whose unauthorised visit led to Aung San Suu Kyi’s prosecution has himself been sentenced to seven years imprisonment, four of which will be for hard labour.

Four employees of the Rio Tinto Group have been formally arrested in China on charges of bribery and using improper practises in its negotiations with Chinese companies. The Chinese accuse the men of improperly learning the negotiating position of Chinese companies wishing to buy iron ore, and through this charging 700 billion yuan (US$102.46 billion) more then they would otherwise have been able to

The four were initially held on espionage charges and have been held since early July. The formal charges allows the Chinese authorities to hold the four a further seven months as it prepares its case against them. Their arrests followed the collapse of an attempted by Chinese owned Chinalco to raise its stake in the Anglo-Australian Rio Tinto Group to 18%.

Michael Jackson will be the star of a film to be released on October 28, some four months after his death. The film will be primarily cut from footage of Jackson rehearsing for the series of concerts that would have taken place at the O2 in London, but will also feature interviews with Jackson’s family and friends.

The film becomes possible after AEG Live, the promoter of the O2 concerts, reached an US$60 million agreement with Columbia Pictures for over 100 hours of footage of Jackson preparing for his swan song.

“He was the architect of ‘This is it‘, and we were his builders…” said Kenny Ortega, Jackson’s collaborator on the project “…it was clear that he was on his way to another theatrical triumph.”

A car bomb exploded today at the gates of a U.S. military base, just outside the Afghan capital of Kabul. According to officials, at least twelve people received injuries. The Taliban immediately claimed responsibility for the attack.

The incident occurred just outside an US installation dubbed “Camp Phoenix”. This is mainly used by American troops which train Afghan security forces.

Camp Phoenix is often attacked by insurgents, particularly suicide bombers. In mid-November, an attack in Camp Phoenix, injured 25 people, half of them American soldiers.

The Taliban was the group that claimed responsibility for the attack. A spokesperson for the bombers, Zabihullah Mujahid, claimed in a telephone interview that the bomber had allegedly “killed and wounded” ten American soldiers and demolished three military vehicles.

Asked about that claim, an American military spokeswoman, Air Force Master Sgt. Sabrina D. Foster, said that a statement would be issued soon but that in the meantime she could confirm only eight United States personnel with minor wounds. According to Kabul police chief Abdul Rahman, three of those injured were American interpreters.

Sayed Abdul Ghafar, head of the criminal investigation, Kabul police, said the explosion demolished at least eleven civilian vehicles in the adjoining area. Eight were wounded, most of whom were day laborers who generally would be leaving the base after a day’s work. All were reported to be stable by Interior Ministry spokesman, Zemary Bashary.

“The target of the suicide attacker seemed to be foreign forces, but we couldn’t see any American vehicle damaged there because the road was blocked by American forces. We don’t know exactly the casualties among the foreign forces,” said Ghafar.

The American troops soon blocked the area, and barred access to the highway. “They won’t even let the Afghan National Police near it,” said an Afghan policeman near the place where the attack occurred.

It was the first suicide bombing in Kabul since January 18. In the previous attack, several bombs had been detonated by the attackers, who also fought with Afghan commandos. The situation was brought under control soon; however five people were killed. Earlier today, Afghan intelligence officials provided another statement about this attack; this statement is probably the one with most details.

During a news conference, they showed a video which was about an Afghan man arrested for allegedly assisting in the attack. In the video, the man, named Kamaluddin, claimed that he received his orders from the Haqqani network. The latter is a militant organization based in Pakistan’s North Waziristan tribal area. He calmly clarified that he had housed the seven attackers before the attack and had provided them with several weapons.

On Thursday, United States President Joe Biden signed the American Rescue Plan Act, a USD 1.9 trillion stimulus relief package that provides a maximum of $1400 in direct payments to individuals making no more than $75 thousand annually. The bill was passed in the United States House of Representatives with a 220–211 vote on Wednesday and in the United States Senate with a 50–49 vote along party lines through budget reconciliation.

The bill includes $300 billion in unemployment benefits through September and expands the tax credit per child to $3600. The bill also supplies $350 billion to state as well as local governments and $14 billion for distributing vaccines. The bill offers a funding of $130 billion in schools, which would help them reopen safely. Small businesses will get $50 billion, and the Paycheck Protection Program will get $7 billion. Small and mid-sized restaurants, which have been hard hit by the COVID-19 pandemic, will be given $25 billion in relief.

White House Press Secretary Jen Psaki said US citizens will begin receiving a first round of direct deposits in their bank accounts by the weekend. Additionally, Biden gave a primetime address to discuss how the country will continue fighting COVID-19 after it was proclaimed as a pandemic by the World Health Organization the previous year. Biden and Vice President Kamala Harris are to travel Atlanta, Georgia and promote the legislation across the country on Friday.

Acting teacher and director Milton Katselas died Friday at age 75, after suffering from heart failure at Cedars-Sinai Medical Center in Los Angeles, California. He began the Beverly Hills Playhouse in 1978 and taught acting classes there to noted actors including George Clooney and Gene Hackman. Katselas is survived by a sister and two brothers.

Katselas directed an off-Broadway production of Edward Albee‘s The Zoo Story, and received a Tony Award nomination for his 1969 direction of Butterflies are Free. Actress Blythe Danner won a Tony Award for her role in Butterflies are Free under Katselas’ direction. He moved to California to direct the film version of that play, and went on to direct films and television movies. Actress Eileen Heckart received an Academy Award for her role in the film version of Butterflies are Free.

Katselas directed the San Francisco and Los Angeles productions of the play P.S. Your Cat Is Dead! by playwright James Kirkwood, Jr. In his author’s notes in the publication of the script, Kirkwood acknowledged Katselas, and wrote that the plays were “directed with incredible energy and enthusiasm by Milton Katselas, to whom I am extremely indebted”.

Katselas directed the television movie Strangers: Story of a Mother and Daughter, and actress Bette Davis received an Emmy Award for her role in the movie. Katselas taught many famous actors including Michelle Pfeiffer, Richard Gere, Robert Duvall, Jack Lemmon, Al Pacino, Goldie Hawn, Christopher Walken, Burt Reynolds, George C. Scott, Elizabeth Taylor, Richard Burton, Alec Baldwin, and Patrick Swayze. Katselas was credited with being able to nurture actors with raw talent so that they could develop strong Hollywood careers. He utilized innovative techniques in his courses – one course called “Terrorist Theatre” had a simple premise: successfully get an acting role within six weeks or leave the course.

He grew up in Pittsburgh, Pennsylvania to parents who had immigrated from Greece, and graduated from Carnegie Mellon. He studied acting with Lee Strasberg in New York at the Actors Studio, and received advice from directors Joshua Logan and Elia Kazan.

Katselas was a prominent Scientologist, and a July 2007 profile on Katselas in The New York Times Magazine observed that some of his students stopped taking courses at the Beverly Hills Playhouse because they felt they had been pressured to join the Church of Scientology. According to the article, Katselas credited Scientology founder L. Ron Hubbard “for much of his success in life”, and one of his students works at Scientology’s Celebrity Centre. The article commented that some in Los Angeles view the Beverly Hills Playhouse as “a recruitment center for Scientology”.

Katselas met L. Ron Hubbard after moving to California, and began studying Scientology in 1965. The New York Times Magazine reported that he had reached the level of “Operating Thetan, Level 5, or O.T. V.” in 2007. According to The New York Times Magazine when Scientologists proceed up the “The Bridge to Total Freedom” they learn the story of Xenu, and that: “75 million years ago the evil alien Xenu solved galactic overpopulation by dumping 13.5 trillion beings in volcanoes on Earth, where they were vaporized, scattering their souls.” A Church of Scientology publication, Source, lists Katselas as reaching O.T. V. in 1989.

Though some actors felt pressured to join the Church of Scientology after taking courses at the Beverly Hills Playhouse, at least one individual felt Katselas was not active enough with the organization. Actress Jenna Elfman left the Beverly Hills Playhouse because she felt Katselas was not committed enough to Scientology. Katselas had previously directed Elfman in half of Visions and Lovers: Variations on a Theme, two one-act plays about relationships that he had written himself. In 1999 Katselas had planned to adapt the script of Visions and Lovers to a film version, and Elfman was set to reprise her role from the play. In an article in Variety about the project, Elfman commented on her experience working with Katselas: “He is brilliant, and knows me so well as a person and an actress that he gets the most out of me.”

Other prominent Scientologist actors who have studied under Katselas include Giovanni Ribisi, Jason Lee, and Leah Remini. According to Rolling Stone, Katselas also recruited actress Kelly Preston to Scientology. Actress Nancy Cartwright (the voice of Bart Simpson), told Scientology publication Celebrity that Katselas motivated her to get more active in Scientology, and she stated she took the organization’s “Purification Rundown” and her life “took off completely”.

Anne Archer was introduced to Scientology while studying at the Beverly Hills Playhouse, as was former Scientologist and now outspoken critic actor Jason Beghe. Beghe told Roger Friedman of FOX News in April 2008 that “He [Katselas] gets kickbacks”, and that he was brought to a Scientology center by fellow Beverly Hills Playhouse classmate Bodhi Elfman, Jenna Elfman’s husband. In a 1998 article for Buzz Magazine, Randye Hoder wrote “In his class, Katselas is careful not to label anything as a tenet of Scientology, but there is no question that the church’s influence seeps into the playhouse.”

Anne Archer’s husband and fellow Scientologist, producer Terry Jastrow, commented to The New York Times Magazine that Katselas changed the way he experiences life on a day-to-day basis: “I go out in the world and look at human behavior now. I see a woman or man interacting with a saleslady, and I see the artistry in it. Life is an endless unspooling of art, of acting, of painting, of architecture. And where did I learn that? From Milton.”

Actor Anthony Head of Buffy the Vampire Slayer spoke highly of Katselas in a 2002 interview with San Francisco Chronicle: “He’s this wonderfully intuitive teacher and his premise is basically: The only real barriers are the ones we put in front of ourselves. If you say, ‘My character wouldn’t do that’ — bollocks! Ultimately it’s you who wouldn’t say that. Who knows what your character might do.” In the acknowledgements of her 2004 autobiography Are You Hungry, Dear?: Life, Laughs, and Lasagna, actress Doris Roberts wrote: “I thank my friend and acting teacher, the incredible Milton Katselas, for his insights, wisdom, and inspiration, which have helped make me the actress that I am.”

Katselas authored two books: Dreams Into Action: Getting What You Want, first published in 1996 by Dove Books, and Acting Class: Take a Seat, which came out earlier this month. Dreams Into Action, a New York Times Bestseller, sought to modify motivational acting exercises to the field of business.

In an interview in the 2007 book Acting Teachers of America, Katselas commented on his experiences as an acting teacher over the years: “I have very special teachers here at the Beverly Hills Playhouse—some have been with me for over twenty-five years. I believe that to make a difference over the long haul, we need to train teachers. I really care about the craft of acting. It’s absolutely necessary to take the time and patience to really develop an actor.”
