In an internet-based study published today on the website of the British Medical Journal, Australian investigators tested how well Googling could help to establish a difficult diagnosis. The search results met against their criteria in 15 out of 26 cases.

Previous anecdotes of the use of Google in reaching a difficult diagnosis are presented in the paper. In a case described in the New England Journal of Medicine (NEJM), a physician diagnosed IPEX syndrome after submitting the typical diagnostic clues to the search engine. A patient’s father replied to doctor’s saying that his son had acute subclavian vein thrombosis of unknown origin: “But of course hehas Paget-von Schrötter syndrome.”

Hangwi Tang and Jennifer Hwee Kwoon Ng from the Princess Alexandra Hospital in Brisbane selected clinical cases from the NEJM blind to the correct diagnosis. They selected 3 to 5 rather specific features, searched Google, and selected the 3 disorders from the results that seemed to fit the case best. If one of those was right, Google was said to be “right”.

The scientists admit that an internet search probably works better with specific symptoms rather than with phrases such as “fever ill pain”. Also, the percentage may depend on the operating physician’s knowledge base, and the test was not double-blind.

Experts commented that the internet is not a replacement for doctors, but should be seen as a way of supporting doctors and patients. A spokeswoman for the Patient Association added that “a lot of sites are not credible. There are lots of good sites out there, but we also know that there are many that are not credible.”

A car bomb that exploded at about 20:00 MDT Thursday (01:00 Friday UTC) in a violent area of Ciudad Juárez, Mexico killed several people and injured more.

Police spokesman Jacinto Seguro said Friday that Mexican federal police received a call that an officer was dead. Seguro went on to say, “When they went to check the car, there was a dead body in there, dressed up like a police officer, but it wasn’t one of ours. They put him in a civilian car but dressed him up in a municipal police uniform. That’s when the bomb went off. It’s like an act of terrorism.”

Federal police spokesman Ramon Salinas said the blast killed two officers, a paramedic, and one civilian, although Mayor Jose Reyes said that only three died. At least six others were injured, although reports have said the total injured may be as high as sixteen. Four remain in the hospital, including three paramedics and one civilian.

Mexican authorities say it was a car bomb, but counter-terrorism experts are still unsure as to what caused the vehicle to explode. Intelligence expert Fred Burton said, “For this to be an improvised grenade attack, in some capacity, it doesn’t surprise me.”

The Juárez Cartel, one of the two drug-traffickers in the area, claimed responsibility for the bombing in a graffiti message. “We have more car bombs,” the graffiti said.

Ciudad Juárez has a history for trafficking drugs to the United States, especially into Texas.

Before the explosion, the police arrested a suspected leader of the Juarez cartel, Jesus Armando Acosta Guerrero.

This year more than 7,000 people have died as a result of drug-related violence in Mexico since this year began. Attorney General Arturo Chavez on Friday said nearly 25,000 people have died in the last three and a half year period.

The Walt Disney Company has today announced the inclusion of a Christmas special in its animated comedy series Phineas and Ferb. The special, entitled “Phineas and Ferb’s Christmas Vacation,” will follow the series’ protagonists, stepbrothers Phineas and Ferb, trying to spread Christmas cheer across their city after the mad scientist Dr. Doofenshmirtz uses a machine to cancel the holiday.

Disney has high expectations for the special. On November 27, the company will stream one of the seven musical numbers that will be showcased in the special on its public radio network Radio Disney. The official special is set to air accordingly the following month on December 6, 2009, on the company’s cable network Disney XD. Soon after, it will air on fellow Disney networks Disney Channel and ABC Family.

The crew of the series too have high hopes for the Christmas special. Zac Moncrief, who directed the special, announced that he believes it will “go down in history as a cartoon classic.” When asked about the special, co-creator Jeff “Swampy” Marsh explained, “It’s kind of intimidating. You sit down and think, ‘This is something that’s going to live at Christmas for a long, long time.'” Dan Povenmire, the other co-founder, said of his excitement over the featured musical numbers, “[H]opefully they’ll be songs that this generation of kids will think of as Christmas songs the same way that kids think of ‘Dahoo dore’ (from ‘How The Grinch Stole Christmas‘) or ‘Rudolph The Red-Nosed Reindeer.'”

Darwin’s Ltd. opened a second location of their sandwich shop at 1613 Cambridge Street in Cambridge, Massachusetts, in late May. It is situated across from Cambridge Rindge and Latin School. Previously limited to one location at 148 Mount Auburn Street, the second store seats approximately 30 people and sells sandwiches, coffee drinks, locally made pastries, as well as some produce and snack foods. The establishment also provides free wireless access through the WanderingWifi service. The shop plays music during the day; during this reporter’s visit to the shop, selections played ranged from David Bowie to The Strokes. The store is air-conditioned.

Key differences between the original store and the new one include the unification of the cafe and the sandwich line now behind one counter, handicap accessible restrooms, no beer or wine sold at location, and a lack of a loyal customer base. Although the recent months have been slow, business is expected to pick up with the return of Cambridge area students this autumn.

While the original location of Darwin’s was recently cited for lacking sneeze guards before the kitchen counter, according to the Cambridge Chronicle, the new Darwin’s has acrylic sheets along the front of their sandwich counter. The original Darwin’s has installed the sneeze guard at the kitchen counter the day following citation.

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.

A new law that proposes no spitting, swearing, or urinating in public passed its second reading in Calgary.

Calgary City Council is expected to pass it into law later this year.

Fines would range from $50 for carrying a visible knife or standing on public benches and $300 for urinating or defecating in public. People who spit would face a $100 fine and those who fight in city streets would pay a $250 ticket.

“You have to set the groundwork of expectations — mutual expectations — in order to be able to work well together, live well together,” said Ald. Madeline King, a councilor who represents part of Calgary’s inner city. “This is the right thing to do — this is a social contract between Calgarians that calls for a minimum amount of respect,” he said.

“Unless you have rules, things don’t work so well in terms of living together harmoniously,” said Ald. Madeleine King. “It’s not targeting the homeless, it’s targeting anyone who behaves in this way.”

It will come back to council for final approval next week.

City lawyers have concerns about enforcing some parts of the legislation.

A recent revelation by American actor John Travolta in court testimony during an ongoing extortion case in The Bahamas that his late son Jett suffered from autism, has stirred debate and controversy over the disease. News media and critics have questioned whether Travolta and his wife Kelly Preston should have acknowledged Jett’s illness sooner. In response to comments made Tuesday about the recent events on the ABC television program The View, the National Autism Association issued a press release stating they “very much support the Travolta family and all families affected by autism”.

Travolta’s testimony last week admitting that his son was autistic was the first time he had stated as much publicly; previously he and his wife had only said Jett had experienced Kawasaki syndrome. Travolta’s son Jett died in January 2009 at the age of 16 after experiencing a seizure. “My son was autistic and suffered from seizure disorder. Every five to ten days he suffered seizures which lasted 45 seconds to a minute,” said Travolta in his court testimony on September 22. A piece in iVillage noted Travolta had been pressured for years to speak out publicly about his son Jett’s autism. iVillage cited a 2007 piece in the New York Post, where a source commented “He could do so much good for autism awareness if he would just come forward.”

News media and critics have suggested that Travolta and his wife’s allegiance to Scientology was behind their rationale for not previously acknowledging that Jett was autistic. The Church of Scientology opposes psychiatry and does not recognize autism as an affliction. Church representative Tommy Davis had told MSNBC that “The Church of Scientology has no position on autism,” however a Scientology-founded organization the Citizens Commission On Human Rights stated to the United States Senate in 2008: “The Citizens Commission on Human Rights believes that there is no known medical treatment for autism except off-label drugs.”

Former Scientologists Tory Christman and Claire Headley were interviewed about the recent revelation by Travolta for The Daily Beast, and commented on its implications. Christman suffers from epilepsy, a condition which also causes seizures. She told The Daily Beast that the Church of Scientology pressured her to go off of her seizure medications, and instead take “vitamins and supplements”. After doing so, Christman experienced a grand mal seizure and knocked out two of her teeth in the bathroom. Headley, who has filed a lawsuit against Scientology for labor-law violations, told The Daily Beast that the only techniques that Scientology would have sanctioned to help Jett would have been internal procedures known as “assists and objective processing”. Church representative Tommy Davis responded to The Daily Beast: “This religion is utterly and completely about helping. It’s just insane to think that Scientology would be a factor in somebody not getting all the help they need.”

ABC News reported Tuesday that the president of the National Autism Association (NAA), Wendy Fournier, stated those that had experience with autism awareness had previously recognized signs from media video that Jett Travolta suffered from the disease. Fournier commented: “It didn’t really come as a surprise for people. But I’ve read some things that really bother me – basically that they should have come forward sooner. Everybody handles autism in the best way that they can and for whatever personal reasons they had, they chose not to make it public. Just because you have a child with autism and you’re a celebrity, it does not automatically mandate you to be a spokesperson for the disorder.” Another official from the autism community, the national manager for Talk About Curing, Autism Rebecca Estepp, said to ABC News: “The Travoltas are suffering right now from a tragedy that could affect anyone. … We’ve heard of several children passing away with seizures lately.”

On Tuesday’s edition of the ABC television program The View, co-host Whoopi Goldberg commented on the statements made by the representative of the National Autism Association to ABC News about Travolta’s admission of his son’s autism. “Since John Travolta has testified his son Jett was autistic in this blackmail case, the National Autism Association has come out saying they didn’t expect him to be a celebrity spokesperson for autism, but he should have come forward sooner,” said Goldberg.

The View co-hosts proceeded to discuss whether Travolta should have publicly revealed his son’s ailment earlier, and the impact of labels in society and the media. Sherri Shepherd commented on the negative impact of labeling individuals, and guest-host Gloria Estefan remarked: “I don’t like labels, period.” “I guess what is stunning to me is that anyone has the right to expect you to say anything about your family,” said Goldberg.

“Isn’t it partly that he’s a Scientologist and that there’s a reputation that Scientologists don’t believe in diseases of certain kinds?” asked co-host Joy Behar. Goldberg asserted that it was the individual’s decision whether or not to speak publicly about such an issue. Shepherd pointed out that celebrity actress Jenny McCarthy has spoken out publicly about autism, which her son suffers from, and noted that her voice has helped to focus public attention on the disease.

Behar questioned Travolta’s earlier statements that his son had Kawasaki disease: “The thing about Travolta though – he called it Kawasaki disease. Did he know that it was autism, and just said it was Kawasaki – was he making that up? I don’t know.” Goldberg said: “This is not the way to get people to come out and say, ‘You know what, I’m going to take a stand.’ It’s just, it’s none of your business until somebody wants to make it your business, but that’s just me.

After the program’s broadcast, the National Autism Association came out with a press release Tuesday, in response to statements made on The View. “The National Autism Association stated today that they very much support the Travolta family and all families affected by autism”, said the press release. The NAA clarified that the statement made to ABC News by its president Wendy Fournier was the opposite position of that quoted by Goldberg, asserting that it was taken out of context. “I agree with Ms. Goldberg, the Travoltas, like any other family struggling with the illness of their child, are entitled to their privacy. I have read hurtful, judgmental comments from individuals as well as organizations, suggesting that that the Travolta family owed it to the autism community to use their celebrity to bring awareness to the disorder. I couldn’t disagree more,” said Fournier.

The organization’s board chair, Lori McIlwain, commented in the press release: “NAA is here to support families and fellow parents. This debate does not serve anyone. As a nation, we need to instead focus on helping those affected by autism, which now affects 1 in 100 children.” According to the release, the organization was founded in 2003, and is one of the largest in the United States. The NAA’s mission includes educated families about autism and neurological disorders.

Cleveland, Ohio-based University Hospitals Case Medical Center child and adolescent psychiatrist Dr. Marcie Hall said that according to studies one fourth of autistic children may concurrently have seizure disorder. The director of the Comprehensive Epilepsy Management Center at New York City’s Montefiore Medical Center, Dr. Shlomo Shinnar, stated: “In neurologically-normal children with epilepsy, the risk of death is actually no different than for children without seizures.”
