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.

MediaCorp Radio in Singapore has been fined 15,000 Singaporean dollars (US$9,800) over an on-air stunt in March in which female guests on a radio show were asked to remove their brassieres, and pose for video that was to be posted on the station’s website and on YouTube.

The Media Development Authority said the radio show’s hosts made improper and sexually suggestive remarks about “how fast the bras were removed, as well as the color, design and cup size of the bras, and the size of the girls’ breasts.”

Researchers at University of Malaya say they have developed an erectile dysfunction cure from walnut extract.

“It takes about an hour for the effects to set in and it will last for about four hours,” said Professor Dr. Kim Kah Hwi of the Faculty of Medicine Physiology.

So far, 40 volunteers have tried the Viagra alternative, called “N-Hanz”, with positive results, Kim said. To make one pill, it takes about 3.3 kilograms (about 7 pounds) of walnuts.

An 8-year-old Indonesian boy died after being attacked on Saturday by a Komodo Dragon at Komodo National Park on Komodo.

The boy was attacked while making a toilet stop in a bush, a park official said. “The dragon bit his waist, tossed him and dragged him. His right leg was badly scratched,” park spokesman Heru Rudiharto said. The boy then bled to death.

Attacks by Dragons on humans are rare, though the reptiles, which can grow to a length of 3 meters (9 feet), regularly kill such prey as pigs and small deer. Komodo Dragons are an endangered and protected species, and about 2,000 of them live in the wild, mainly on Komodo and nearby Rinca island.

The United States Congress is currently drafting a bill known as the Communications Opportunity, Promotion, and Efficiency Act of 2006 that would revise and update the 1996 Telecommunications Act. Currently phone and cable lobbyists who own the broadband networks, such as those from AT&T and BellSouth, are calling on the federal government to permit them to operate Internet and other digital communications services as private networks. The bill as it now stands states that certain classes of Internet providers “may not unreasonably” impair, interfere, restrict or limit applications or services, such as Web sites or voice-over-IP phone connections.

Consumer advocates such as Common Cause and some large Internet companies such as Google and Yahoo are concerned that this change will result in a loss of what is being called network neutrality, and are demanding specific language in the bill to address it. Three weeks ago, the House Subcommittee on Telecommunications rejected an amendment to the bill that would have strengthened provisions for network neutrality. The amendment was defeated by a vote of 28 to 8.

Network neutrality is a principle of computer networking that describes networks designed so that no communication, application, or service is either given preferential treatment or restricted.

Advocates of network neutrality fear that allowing broadband networks to operate unregulated could lead to preferential treatment toward certain companies at the expense of others. Phone companies who oppose network neutrality legislation contend that some mechanism needs to be in place in order to pay for expansion of the public Internet.

Edward Whitacre, AT&T’s chief executive officer, had made remarks on the issue that consumer groups found inflammatory. In remarks made on November 7, 2005, presumably referring to Internet sites using their network connections, he called for “some mechanism for these people who use these pipes to pay for the portion they’re using. Why should they be allowed to use my pipes?”

Whitacre has since reversed his public statements, saying on March 21, 2006, “Any provider that blocks access to content is inviting customers to find another provider. And that’s just bad business.”

Federal Communications Commission chairman Kevin Martin believes that the FCC already has the authority to enforce network neutrality provisions, citing a North Carolina case in which the FCC acted against Madison River Communications for blocking Vonage VoIP phone service.

Representative Fred Upton from Michigan, chairman of the Telecommunications and the Internet Subcommittee, describes the bill as a way to “ignite the marketplace — unleashing great advances in technology and delivering to consumers a variety of new services at a lower cost that were once never even imagined. Every consumer in the nation with a telephone, television and access to the Internet will be better for it — the wave of the future is now.”

Michael Copps, a FCC Commissioner, said recently, “This Internet may not be the one we know in the future there are threats to it out there… Entrenched interests are already jockeying to constrain the openness that has been the Internet’s defining hallmark.”

A recent poll done by The Consumer Federation of America (See source 5) shows that the Internet has taken on an important role in the daily life of Americans. With two-thirds reporting it is important for personal communications and researching products, over half said it is important for getting news and, about 40 percent cited online banking, e-commerce, and retrieving government information as significant ways in which they used the internet. They expressed a great deal of concern about discriminatory practices of communications network operators.

The revision of the 1996 Telecommunications Act was proposed by House Energy and Commerce Committee Chairman Joe Barton, R-Texas, and U.S. Rep. Bobby Rush, D-Ill., in late March and went on to the full committee on April 5.

The acrid haze situation in Southeast Asia is worsening. Visibility has been severely reduced in neighboring countries and some schools have been closed due to the health hazard posed. The annual smoke season is caused by illegal slash and burn clearance of land in Indonesia, particularly the island of Borneo.

The haze has spread over 2,250 miles (3,600 kilometers) into neighboring countries such as Singapore, Malaysia, Thailand, and even drifting to Guam in the western Pacific.

Aviation has been severely impaired in Indonesia, where in certain areas, visibility is only a mere 200 to 300 meters. Helicopter service in Malaysia’s Sarawak state, a key mode of transportation there, has been halted due to the poor visibility. A Mandala Airlines Boeing 737-200 carrying a 110 people had overshot the runway at Tarakan airport in Kalimantan province in Indonesia. The aircraft came partly to rest in a nearby swamp. Visibility at the time was around 400 meters, 600 meters short of Indonesian landing safety regulations.

Schools in Thailand, and Indonesia have also been forced to closed, and look likely to stay closed well into next week.

Air pollution indices around the region have also registered a spike in poor air quality. Sarawak state’s index came in at 106-188 with 100-200 being unhealthy. In Malay peninsula, the air pollution index in five states came in at 101-116. In Singapore, the Pollution Standards Index registered between 80-130 with 81-100 in the moderate range and 101-200 in the unhealthy range.

Wikinews journalist Timlee90 reports:

The air quality here in Singapore is so bad that I could feel the dust in my mouth as I was walking on the streets today. The air constantly smells of burning wood and visibility is never more than a kilometer. Singaporeans I know are concerned about the deteriorating situation.

Timothy Low, a Singaporean who’s just finished his national service says that he is concerned about the situation, “I can’t run to exercise. People with lung related problems have difficulty breathing; It causes tearing also.” The government here has advised citizens to reduce vigorous activity, especially those with existing heart or lung conditions.

The Indonesian government has been criticized by environmentalist groups such as Greenpeace, which claims that the allowed conversion of forests into cropland is the cause of the problem. The also call on the Indonesian government to “investigate and hold liable plantation companies responsible for slash and burn clearing”.

The Indonesian government has responded to the criticism that it is doing all that it can do. “We don’t know when we can put out the fires but we are working tirelessly and have spent billions of rupiah (hundreds of thousands of dollars) in our efforts,” Forestry Minister Malem Sambat Kaban said. “As for complaints from neighbouring countries, there’s nothing else we can do. We don’t cause the fires deliberately.”

In 1997-98, the haze cost the Southeast Asian region an estimated US$9.0 billion by disrupting air travel and other business activities

The United States Department of Housing and Urban Development (HUD) will make many of their marketable housing properties in the southeastern United States and elsewhere available to hurricane refugees. HUD Secretary Alphonso Jackson said that an “overwhelming” response from government and private officials would make housing available as soon as the middle of next week. HUD housing centers as far away as Philadelphia and Detroit would be making properties available. HUD is considering offering these properties to displaced persons regardless of their income and allowing the refugees to use the properties for up to one year.

On July 18, 2005 CN Rail notified the CAW that they intend to cancel the CN-CAW previously Negotiated Health & Safety Plan. The CAW will be going to arbitration this fall to address the issue. The CAW has asked that employees notify their Health and Safety Rep about any safety concerns at the work place.

One terminal has lost 5-6 full-time positions. CN Rail used to have part-time positions filled as well, but at this time there are no part-time employees to cover work if a full-time employee is absent. Overtime is necessary to keep the trains running on time. Intermodal traffic goes up, but staff goes down. CN Rail expects the trains to go out on time, and in a safe condition, but staff is overworked, because there are not enough of them. In fact, one worker noticed that most of the rail cars that contained 40 foot overseas containers did not have their loading guides in place. Trains are not allowed to go out without these guides placed into the cars (the guides stop the loads from swaying from side to side in the cars), important for safety with double stacked containers, but it seems that in this case the lack of employees forced the train to leave without them.

Some recent derailments have come to the attention of the media and politicians.

On August 3rd 2005 there was a derailment in Wabamun Lake Alberta that spilled toxins into the lake. 2 days later there was a derailment in Cheakamus River near Squamish BC. Both derailments spilled hazardous materials into the water. Many are saying that CN took too long to notify people of the toxic spills.

The Conductor on each train carries with him the shipping manifest with him and has access to that information at all times. Almost any CN terminal that has a clerk working at it with access to the CN Intranet can get this information within minutes.

CTV news has said that this is the 5th derailment for CN this month.
