Dogs can be trained to detect early and late stages of lung and breast cancer accurately according to a study published by California scientists in the little-known scientific journal Integrative Cancer Therapies.

The study took place over the last five years at the Pine Street Foundation, a non-profit organization which conducts evidence-based research on integrative medicine (combining complementary and alternative medicine and mainstream medicine). Michael McCulloch and colleagues used three Labrador Retrievers and two Portuguese Water Dogs, both common pets, that received basic behavioral dog training. The researchers trained the dogs to lie down next to a sample from a cancer patient and to ignore other samples.

The samples used were breath samples from 55 patients with lung cancer and 31 with breast cancer — the two types of cancer with the highest mortality rates in the United States.

After the training phase, the dogs’ accuracy diagnosis was tested in a double-blind experiment. Among lung cancer patients, the sensitivity and specificity were 99% accurate and for breast cancer sensitivity was 88% and specificity 98%. Because these figures seem almost too good to be true, cancer experts are the same time baffled and skeptical. The authors of the study themselves also say replication of the study is needed.

Importantly, this was independent of the cancer stage, meaning the dogs were able to pick up the scent of cancer in its early stages. This is important because in many cases, the success of any treatment depends on early diagnosis. However, the researchers don’t believe this will lead to the use of dogs in the clinic soon, rather they want to find out which chemicals are actually sensed by the canines, because they could be used in laboratory assays. “It’s not like someone would start chemotherapy based on a dog test,” Dr. Gansler of the American Cancer Society said, “They’d still get a biopsy.”.

The researchers were inspired by anecdotal reports about dogs detecting cancer. In 1989, a British women consulted with her family physician because her Dalmatian kept licking a mole on her leg. At biopsy it showed to be malignant melanoma. When diagnosed too late this form of cancer has a poor survival rate, but in this case early surgery was made possible, and the women survived. Prior studies showed that breath samples from patients with lung cancer or breast cancer contain distinct biochemical markers. This provides a basis for the hypothesis that some cancer types produce volatile chemicals that dogs could smell. A study published in the British Medical Journal already proved that dogs could use their exquisite sense of smell to detect bladder cancer in urine samples, but they were only correct in 41% of cases, and another study provided preliminary evidence that dogs could detect melanomas.

This doesn’t mean you can show your breasts to your dog and it will tell you if you have cancer, other physicians caution, and scientists do not advise people to train their dogs to sniff for cancer. Unresolved issues from the study include the fact that subjects were required to breathe deeper than normal, so it’s not sure whether dogs can smell cancer in normal breath. Also, whether this is a permanent skill that would be retained by dogs was not tested.

Finally, there are concerns that could arise over liability issues: who would be responsible when the dog makes a mistake?

Current detection methods for both lung and breast cancer are not flawless. For lung cancer, chest X-ray and sputum cytology (detecting cancer cells in coughed up fluid) fail to detect many early cases, and CT scan produces many false-positive results unless combined with expensive PET scans. Although it might be comparing apples and oranges, a $2.5 million CT scanner has an accuracy of 85 to 90%. Mammography also produces false-positive results, and it may be difficult in women with dense breast tissue. As such, another type of “pet”-scan, using dogs as a biological assay, might prove feasible for screening if supported by further research. Current tests are also expensive so the use of dogs for preliminary cancer testing could prove to be an affordable alternative for countries in the developing world.

Brampton – Suresh Joachim of Mississauga, Ontario continues to amaze, breaking yet another world record, this time at The Bay Court in Shoppers World.

From Thursday, September 22 at 8 am, to Saturday, September 24 at 3:05 pm, Suresh ironed continuously for 55 hours and 5 minutes, in front of the thousands of onlookers shopping at the mall those three days.

The achievement, now submitted to the Guinness Book of World Records, breaks the previous record by Eufemia Stadler of Zurich, Switzerland. Stadler completed 40 hours of continuous ironing from September 16-18, 1999.

Originally from Sri Lanka and Australia, Joachim is no stranger to the folks at Guinness. He currently holds twenty other records, ranging from greatest distance travelled on ‘up’ and ‘down’ escalators (225.44 km between May 25 and May 31 1998), furthest travelled on a treadmill in one week (659.27 km at a gym in Paris, France), and longest dance marathon by an individual (100 hours at the Dixie Outlet Mall).

This September, Suresh watched television in the lobby of WABC in New York City for 69 hours and 7 minutes, breaking the previous record by 19 hours. The event was covered daily on the talk show “Live with Regis and Kelly” as part of their Guinness World Record Breaker Week. He also recently set the record for longest time rocking in a rocking chair, at 75 hours.

A DJ on BBC Radio Cambridgeshire recently tried to break Joachim’s record for longest continuous time as a DJ. He was unsuccessful, and Suresh’s 120-hour World Record set on Geethavaani Tamil Radio in Scarborough stands unharmed.

The event helped raise funds for the Universal Fund for Suffering Children, whose funds are “utilized to save the world’s children from poverty, disease and war.” All of Joachim’s stunts have been dedicated to this charity.

What’s next for Suresh? He plans to start static cycling from October 18th, 2005 to October 22nd, 2005, in Britain. Suresh’s goal is 150 world records, which would beat the long-time record breaker Ashrita Furman, who has accumulated 94 records. While Furman started two decades ago, Suresh only discovered the Guinness Book of World Records in 1991, and started record breaking in 1996.

Police arrested over two dozen anti-war protesters for demonstrating without a permit in front of the White House in Washington, DC on Wednesday.

The rally consisted of protestors organized in a “die-in”, appearing to be deceased. The peace rally was performed shortly after reports that the death toll for U.S. soldiers serving in Iraq reached 2,000.

The left-leaning MoveOn.org led a national campaign to galvanize anti-war vigils. Organization members on their e-mail lists received a notice Wednesday that read: “Dear MoveOn member, Yesterday we reached the sad milestone of 2,000 killed in Iraq. But for the most part, the national media are ignoring this tragic milestone.”

Phyllis Bennis of the Institute for Policy Studies said that changes in U.S. public opinion are showing signs that peace activists are “beginning to give voice to the majority in this country.”

Among those arrested was activist Cindy Sheehan. She was arrested for the same offense in another anti-war demonstration just last month.

Three days after the Internet release of the free content 3D short Elephants Dream (see Wikinews coverage), we exchanged e-mails with Ton Roosendaal about the reaction to the film, open source filmmaking, and the changes to Blender that resulted from the production. Ton Roosendaal is the lead developer of the Blender 3D rendering and modelling software that was used for the movie. He is also the chairman of the Blender Foundation, a non-profit organization which was formed in support of the software and projects like Elephants Dream.

How much money did the Blender Foundation spend on producing the movie? Has the money been fully recouped by DVD orders and donations?

We still have to finish the final bookkeeping for this project. It has been executed in co-production with the Netherlands Media Art Institute, and we each had our own internal budgeting for the project. When you exclude expenses of pre-production and producer personnel, the total budget was about 120,000 €, of which we covered half. Our contribution was roughly covered half by the DVD sales, and half by European Union support (http://www.uni-verse.org consortium).

One of the most common criticisms of CGI films is focus on technology over content. For instance, Final Fantasy: The Spirits Within flopped with audiences, in spite of being an undisputed technical milestone. I’ve seen many reviews that criticized the plot of “Elephants Dream” as too bizarre or confusing. In retrospect, are you happy with the story development process?

Haha, I knew the story and plot would get a mixed acclaim. There’s a couple of reasons I’d like to mention for it.

First of all; the criticism resembles how people witness Blender itself, too. Many people expect that Free Software is an easy accessible mass audience product. We get a lot of complaints by non-artists that they can’t get into the software easily, whilst the complexity of commercial products like Maya or Houdini is perceived as a confirmation of its “quality”. Apparently an Open Movie created similar expectations with the audience.

Luckily we also got many positive reviews of the artistic result of the movie. It is quite abstract, but definitely has many layers of information, inspiring many of the viewers to see relevant real life messages hidden here.

For this project we’ve teamed up with the Netherlands Media Art Institute, internationally renowned as a resource for video art. So for Elephants Dream, we’ve had the luxury to challenge ourselves to create real independent artistic content as well. The artists had a lot of freedom from the start; they were responsible for the concept, story and creative development of the entire movie. This has resulted in a lot of quite personal choices, based on what the artists liked to do themselves. I really cherish such an approach, it has resulted in a very motivated team working crazy hours the last months to get it all realized.

But, most importantly; the main target of our project was not only to create a 3D movie short, but to experiment with ways to improve the efficiency and quality of open source development. On this aspect only, this project was just a huge success, and the main reason for our sponsors (the DVD pre-sale) to support it. I know they might have liked a cartoonish funny movie with furry animals better, but for that you get already pretty well served by the bigger 3D animation studios. 🙂

I’m the first to admit that – looking back especially – certain aspects worked out quite weakly; there’s loose ends and questionable decisions, especially in story development and continuity. That’s just the risk of doing experiments, and nothing I regret really. The five artists from our user community who were invited to make the movie were young people with no professional background in filmmaking. Their personal incentive to participate in this project was also to learn from it, and to create a good portfolio for their future career. I’ve witnessed them grow in competence in the past year enormously, something I’m incredibly proud of.

On the technical level, the only major criticism I’ve seen of “Elephants Dream” is the character animation, especially in the opening scene — many reviewers felt that the movements seemed a bit unnatural. Do you agree with these criticisms? If so, what do you think can be done to improve on that level?

Yeah, the challenge the artists set themselves – to use quite realistic personages – is also something that easily works against you. In many animation movies they introduce characters in the beginning in a way you get used to their specific characteristic movements, so you accept a certain level of non-realism easily. (Check the weird walk cycles in The Incredibles for example). Another aspect is that we’ve started work on the first scenes, and ended with the last scenes. I can clearly see the animation quality increase, and that whilst the ending scenes were done in much less time due to time constraints.

We also didn’t schedule to do 9.5 minutes of animation either…. Originally it was more like 6. But, it’s always easier to look back to define the right decisions, eh? 🙂

I’m very happy with the reviews we got so far; luckily the movie was perceived as a professional quality product, and reviewed based on comparisons with what the big studios come up with. Even when we couldn’t satisfy all these quality demands, it has luckily not been branded as a pathetic presumptuous attempt by amateurs!

Do you think there is hope for a full-length open movie project in the near future? Would the Blender Foundation be interested in such a project, or do you intend to continue focusing mainly on shorts?

I’d like to wait a little while with defining what a next project would look like. Given the constraints of “organizing projects to improve open source development”, we might have not much choice either. It would probably mean to work with a new team each time, so most likely be based on shorts only. On the other hand, there’s also clear signals that this approach works well, and creates excitement and involvement of a lot of people, also from producers and sponsors. That might enable us to set up a next project based on larger targets. For a full-length feature film however, we should involve a sufficient amount of experienced film makers as well, and/or invite the first team to participate again. That would put a lot of pressure on the required budget…. You can’t do that based on a 1000 DVD pre-sale target. Would more be like 20,000 or so…. 🙂

How did the process of making the movie feed back into the development of Blender? Are there major technical changes that were made only or primarily because of the film?

Already during the pre-production phase the artists have defined the key targets for Blender development. This then was coordinated with the online development community too. I’ve done the most crucial (re-)development mostly myself, though. Especially on the character animation tools, on the rendering pipeline and compositing tools.

It is especially the latter I’m most satisfied with. In 3D movie production the compositing stage creates a giant content bottleneck. By transparently integrating this in our render-pipeline, a very efficient workflow has been achieved. And, not to forget, Blender now also offers the first production-level open source compositor on the market!

The current summary you can find in our work-in-progress release notes.

What are the key technical features in Blender you want to add or improve for future movie projects?

Depends on what the movie is about! There’s always hundreds of features you can work on. However, we’ll have to work on that anyway, movie project or not. There’s a lot of professionals using Blender now, and they can’t wait for the Blender Foundation to do movies! Look at this studio for example:http://www.plumiferos.com/

I read that at least one proprietary software package, Reaktor, was used for the sound effects. Is this because no equivalent free software solution exists yet? Will future projects have a “free software only” policy?

We’ve limited the “Open Source tools” requirement to our own Studio Orange only. That was what we could keep in control at least, and I can tell you it was not always easy even… 🙂

For sound and music we’ve decided from the beginning to seek an external sponsor. We have chosen to work with the best quality studio and composer we could find, preferably using open source, but not as a prerequisite.

My own competence is solely within the CG [computer graphics, Ed.] side of movie making. When it comes to music editing, or video encoding and DVD authoring, I could only decide to choose to work with external parties with proven competences in that area. I have to be practical in projects like this, especially to ensure it will be realized.

Hopefully, now we’ve got so much attention world wide, we can involve more non-CG open source next time, too. I will definitely strive for the maximum here, but it will fully depend on the amount of professional support we can get.

Blender itself was originally closed source freeware, until it was “liberated” through a fundraising campaign. If you could choose one proprietary application to “set free” where such a goal could be realistically achieved, which one would it be?

Well, the “realistically achieved” demand makes it quite difficult. 🙂 Looking back at similar cases, like Mozilla and OpenOffice.org, it was always very circumstantial. It just happens sometimes, you can’t organize something like this to happen in advance. The only common denominator is “a company in troubles”… so, who’s in trouble now?

What is your personal favorite computer-animated full-length film?

Uuuh… that differs every week! Probably Ice Age (the first one). Mostly because they didn’t overdo showcasing 3D technology so much, but created truly adorable characters and great funny gags.

Scientists at NASA have recently released the most detailed map of Antarctica ever. NASA’s Landsat 7 satellite took 10,000 photographs of the continent over a period of two years, from 1999 to 2001. 1,100 pictures were chosen to form the mosaic map. Officially titled the Landsat Image Mosaic of Antarctica (LIMA), the map reveals Antarctica’s geography in high definition and with accurate colors. Details as small as half the size of a basketball court are visible.

NASA created the map to coincide with the International Polar Year of 2007-2008. Robert Bindschadler, chief scientist of the Hydrospheric and Biospheric Sciences Laboratory at NASA’s Goddard Space Flight Center, remarked, “This innovation is like watching high-definition TV in living color versus watching the picture on a grainy black-and-white television.” The map represents a tenfold improvement over previous Antarctic imagery databases.

Landsat 7 managed to capture 80% of the continent in high definition. While the satellite was not able to take photographs of the South Pole due to its orbit path, lower-resolution images helped fill in the gap.

The map will help scientists plan and carry out expeditions on the notoriously difficult terrain. The new, intensely detailed information will also facilitate the tracking of environmental changes such as the calving of ice shelves. Researchers will be able to use such data to better understand phenomena like global warming in such amazing detail that even relatively small changes will be visible. Geologists, on the other hand, will be able to use the maps to study Antarctic rock formations.

The LIMA images are available to the public via the internet. The National Science Foundation contributed nearly US$1 million to create the website.

The Landsat 7 satellite will continue to document Antarctica from space through to 2011. Subsequently, NASA will launch the Landsat Data Continuity Mission. Information from both projects will update the map.

A sticker for the Pensacola, Florida folk-punk band This Bike Is A Pipe Bomb was found on a bike near the Ohio University‘s Oasis restaurant by a university police officer.

The university police, who were unaware of the band’s existence, summoned the Columbus police bomb squad, who destroyed the bike to ensure that there was no bomb inside. The university later discovered their error.

The bike’s owner, a graduate student, has been charged with “inducing panic,” a misdemeanor. He has been released and is due to appear in court March 13 on the charge.

The band’s label, Plan-It-X Records, has not yet commented on the incident. The font and style of the sticker are common among such humorous stickers.

Businessman Rocky De La Fuente took some time to speak with Wikinews about his campaign for the U.S. Democratic Party’s 2016 presidential nomination.

The 61-year-old De La Fuente resides in San Diego, California, grew up in Tijuana, and owns multiple businesses and properties throughout the world. Since getting his start in the automobile industry, De La Fuente has branched out into the banking and real estate markets. Despite not having held or sought political office previously, he has been involved in politics, serving as the first-ever Hispanic superdelegate to the 1992 Democratic National Convention.

De La Fuente entered the 2016 presidential race last October largely due to his dissatisfaction with Republican front-runner Donald Trump. He argues he is a more accomplished businessman than Trump, and attacks Trump as “a clown,” “a joke,” “dangerous,” and “in the same category as Hitler.” Nevertheless, De La Fuente’s business background begets comparisons with Trump. The Alaskan Midnight Sun blog described him as the Democrats’ “own Donald Trump.”

While receiving only minimal media coverage, he has campaigned actively, and according to the latest Federal Election Commission filing, loaned almost US$ 4 million of his own money to the campaign. He has qualified for 48 primary and caucus ballots, but has not yet obtained any delegates to the 2016 Democratic National Convention. Thus far, according to the count at The Green Papers, De La Fuente has received 35,406 votes, or 0.23% of the total votes cast. He leads among the many lesser-known candidates but trails both Senator Bernie Sanders who has received nearly 6.5 million votes and front-runner Hillary Clinton who has just shy of 9 million votes.

With Wikinews reporter William S. Saturn?, De La Fuente discusses his personal background, his positions on political issues, his current campaign for president, and his political future.
