The Museum of Contemporary Art Detroit and Cranbrook Art Museum debut Shrinking Cities. The project, which examines urban decline in cities across the globe is sponsored by Germany’s Federal Cultural Foundation.

Shrinking Cities includes contributions from more than 200 artists, architects, researchers, filmmakers, journalists, culture experts, and sociologists aimed not only at showing the effects of this global phenomenon but also exploring how to deal with it.

The project, which began in 2002, involves local teams from four cities: Detroit, USA, Manchester/Liverpool, Britain, Ivanavo, Russia and Halle/Leipzig, Germany. The teams examined the negatives and the positives of urban decline. Along with the exhibit contribution of the team and international idea competition was launched.

Shrinking Cities premiered in Berlin in 2004 and later traveled to Halle and Leipzig Germany. In Detroit it will run from 3 February until 1 April. Cranbrook Art Museum and the newly founded Museum of Contemporary Art Detroit will cohost the exhibit, with buses running in between the two.

Viktor Schreckengost, the father of industrial design and creator of the Jazz Bowl, an iconic piece of Jazz Age art designed for Eleanor Roosevelt during his association with Cowan Pottery died yesterday. He was 101.

Schreckengost was born on June 26, 1906 in Sebring, Ohio, United States.

Schreckengost’s peers included the far more famous designers Raymond Loewy and Norman Bel Geddes.

In 2000, the Cleveland Museum of Art curated the first ever retrospective of Schreckengost’s work. Stunning in scope, the exhibition included sculpture, pottery, dinnerware, drawings, and paintings.

South African president Thabo Mbeki has arrived in Harare today to talk with Zimbabwean president Robert Mugabe about the upcoming presidential run-off election. This comes amid claims that violence has risen in the country over the last few days.

The Zimbabwe Association of Doctors for Human Rights claim there has been a “dramatic escalation in incidents of organised violence and torture” after the recent elections with “more than 900” documented as injured. The organization said in a statement that “the level of brutality and callousness exhibited by the perpetrators is unprecedented and the vicious and cowardly attacks by so-called war veterans on women, children and the elderly shames the memory of all true heroes of the liberation struggle”.

Mr. Mbeki is acting as a mediator for the Southern African Development Community (SADC) and may have discussed elections and the recent crackdown on opposition by the Mugabe government, which has included the arrest of Davison Maruziva, editor of free newspaper The Standard, 22 deaths, the displacement of 40,000 opposition farming families and such a casualty influx into Harare hospitals that they are worried that plaster of Paris bandage supplies will soon be “exhausted”.

Talks between the two leaders at State House lasted for more than three hours before Mbeki left for the South African embassy in Harare.

Morgan Tsvangirai, leader of the largest opposition party, the Movement for Democratic Change (MDC), plans to announce whether he will stand for the run-off election in the South African city of Pretoria, where he is currently residing, tomorrow at 9:00 UTC.

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.

Australian Minister for Vocational Education and Training, Gary Hardgrave has announced the government will provide AU$15.8 million to establish an Australian Technical College in North Adelaide. The minister said the government was entering into a partnership with the Archdiocese of Adelaide and consortium of industrial and manufacturing companies.

The North Adelaide college will be located in Elizabeth and be operated as an independent non-government school. The college is one of 25 to be established across the country.

Enrolments at the college will begin in 2007 and will offer courses in areas where identified skills shortages exist in the North Adelaide region, specifically – engineering, construction, electronics and cooking.

Mr Hardgrave said that the proposed college had been popular among the North Adelaide business community. “This important initiative has been well received by North Adelaide business and industry, and will help to address skills needs and provide opportunities for those in greatest need, including a lot of Indigenous students in the region,” Mr Hardgrave said.

“The fact that this College is being led by local employers, local government and other key stakeholders, means it will be truly industry and community driven,” he said.

Australian Technical Colleges were established to cater for year 11 and 12 students who wish to do an apprenticeship as part of their school education.

The Australian Education Union has expressed a number of concerns about the model put forward by the government. In a report, they claim that trade facilities at TAFE colleges (operated by state governments) will deteriorate as funding is diverted to the ATCs. The union is also concerned that ATCs are supposed to be selective VET schools. According to the union they will have selective entry and preferential funding. It is feared that teachers will be lured away from schools and TAFE colleges to higher paid positions in ATCs.

The Education Union suggested that the government invest in schools that already offer vocational education programs.

January’s second Interview of the Month was with Danny O’Brien of the Electronic Frontier Foundation (EFF) on 23 January in IRC.

The EFF is coming off a series of high-profile successes in their campaigns to educate the public, press, and policy makers regarding online rights in a digital world, and defending those rights in the legislature and the courtroom. Their settlement with Sony/BMG, the amazingly confused MGM v Grokster decision by the Supreme Court of the United States, and the disturbing cases surrounding Diebold have earned the advocacy organization considerable attention.

When asked if the EFF would be interested in a live interview in IRC by Wikinews, the answer was a nearly immediate yes, but just a little after Ricardo Lobo. With two such interesting interview candidates agreeing so quickly, it was hard to say no to either so schedules were juggled to have both. By chance, the timing worked out to have the EFF interview the day before the U.S. Senate schedule hearings concerning the Broadcast flag rule of the FCC, a form of digital rights management which the recording and movie industries have been lobbying hard for – and the EFF has been lobbying hard to prevent.

A new study amongst doctors in the United States on the use of placebos—pills with no medical effect—shows that almost half of the questioned practitioners prescribe placebos, most of them within the last year.

The majority of 466 faculty physicians at Chicago-area medical schools interviewed by a research group of the University of Chicago stated that placebos are useful to calm a patient down or to respond to demands for medication that the doctor disagrees with, i.e. “to get the patient to stop complaining”.

96 percent of the physicians surveyed believe that placebos can have therapeutic effects. Close to 40 percent stated that placebos could benefit patents physiologically as well as mentally.

Twelve percent of surveyed physicians think that placebos should be banned from clinical practice. Among the doctors who prescribed them, one in five said they outright lied to patients by claiming a placebo was medication. But more often the physicians came up with ways to explain like that “this may help you but I’m not sure how it works.”

The American Medical Association (AMA), the largest association of U.S. doctors and medical students, tells its members that “[p]hysicians may use placebos for diagnosis or treatment only if the patient is informed of and agrees to its use.” The research, published in Journal of General Internal Medicine this week, is the first major U.S. study of doctors on the use of placebos since 1979.
