Last month, a study conducted by archæologist Dr. Naomi Martisius and other researchers concluded Neanderthals living in Europe tens of thousands of years ago were more sophisticated than previously thought. The now-extinct species used to carefully select bones from a particular animal species to manufacture their bone tools, the research showed. The research was published on May 8 in Nature’s Scientific Reports journal.

Dr Martisius and her team used five bone tools discovered from Neanderthals’ sites in southwest France for this research. Four of these bone tools were found in a site called Abri Peyrony and the other one was from Pech-de-l’Azé I. These tools were just a few centimetres in size and were about 50 thousand years old, Dr Martisius told Wikinews. Microscopy analysis of these bone tools called lissoirs (smoothers) suggested Neanderthals used these tools for working animal skin to leathers.

The study stated the fauna of the sites were primarily medium-sized ungulates such as reindeer, in one layer nearly 90%. Despite the overabundance of medium-sized ungulates, Neanderthals used ribs of large bovids for making lissoirs. Dr Martisius told Wikinews this was likely due to the physical characteristics of the bovid ribs, which were “thicker” and “stronger” as compared to the “thin and flimsy ribs” of reindeers. In order to check the origins of the bone tools, the researchers used a technology called non-destructive Zooarchæology by Mass Spectrometry (ZooMS).

Instead of damaging the bone artefacts in order to discover its origins, the researchers collected collagen from the plastic containers in which these artefacts were kept. Collagen is a type of protein. These bone artefacts were kept in plastic containers: some were kept for about five years, some for just a few months. During this time, the collagen proteins from bone tools were stuck to the walls of its plastic containers. The collagen samples collected from the walls of the containers are broken into smaller molecules called peptides by using a chemical enzyme called trypsin.

After the trypsin has broken collagen fibres into peptides, it is analysed using a technology called Matrix-assisted laser desorption/ionization (MALDI) Time-of-Flight mass spectrometer (ToF MS). The assisting matrix is a coloured compound. The acidic peptide is combined with the matrix, vapourised, and peptides are released. Some of them are positively-charged particles which travel across a vacuum tube in an electric field. Depending on the weight of the peptides, these molecules reach the end of the vacuum tube at different instances of time, forming a spectrum. These graphs are like unique fingerprints of a species: they are different for different species of animals. Looking at the database of such graphs, taxonomic identifications of the collagen proteins came be made.

All four bone tools from Abri Peyrony gave positive results and showed that the bones were made from large bovids, even though reindeer were more abundant during that time. One of the advantages of using bovid ribs over reindeer’s thin ribs was the bovid ribs would be more resistant to breaking during flexion, Dr Martisius said.

Dr Martisius said such non-destructive ZooMS analysis was previously conducted, but for tools no older than a few centuries. She said such an analysis had never been previously conducted for artefacts so ancient.

Wikinews caught up with Dr Martisius to discuss this research in-depth.

A ban on smoking in public places has gone into force in Spain today. Bars, restaurants, and nightclubs will now be smoke-free across the country.

The Spanish government had introduced voluntary regulations on smoking in 2006 which allowed for venues to ban smoking, but few chose to do so. The 2006 law also banned smoking at workplaces.

Spain now joins Ireland, the United Kingdom, France, and Italy in banning smoking in enclosed public places.

Leire Pajin, the Spanish health minister, said the law marked “a decisive step in the defence of the health of the Spanish people”, but some industry representatives have expressed concern that business will go down following the ban.

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.

Last Tuesday in Taipei, Google Taiwan held an annual summary press conference named “Collective Intelligence & Innovation” (In Chinese: ?????????). With many products had already been presented to the public like wikis, blogs, and photo albums in the Web 2.0 era, Google served to provide lots of services like Google Apps, Google Maps and YouTube with suitable versions in Taiwan differing other countries this year.

Global Deputy Director of Google Kai-Fu Lee said: “The contents on the Internet were mostly limited with some copyright issue in the past, but after many products in the Web 2.0 era are presented, several contents are progressively released and opened to the public in the presence. As those factors, we [Google] hope developers in Taiwan can develop useful tools for local people to apply with people’s life.”

“In order to change minds in public, we [Google] conjoined some required elements into people’s life, and services on iGoogle in Taiwan are progressively more and newer because of the improvements of developers. We hoped a simple service can be multiplied with releases of useful and functional tools,” he also said.

Also in this conference, the Engineering Director of the Google Taiwan R&D Center Li-feng Chien also announced the achievements on the “Google Taipei Developers’ Day” and invited developers named Chi-pao Hu and Yi-ru Lin to share some actual applications on iGoogle.

Yesterday morning near the international airport located on Weno island of Chuuk state of the Federated States of Micronesia, Oceania a passenger airplane of model Boeing 737-800 flown by the Air Niugini carrier crashed into sea as its pilot missed the runway. All 47 people on board — by differing reports, 36 passengers and eleven crew or 35 passengers and twelve crew — survived.

The report by the international commercial aviation safety organization Jet Airliner Crash Data Evaluation Centre indicated the crash coincided with a sudden intensification of the weather conditions. timeanddate.com-supplied data from CustomWeather reported rain showers at 9:40 a.m. local time, following cloudy conditions at 8:50 a.m.

The airplane reportedly landed around 9:30 a.m. local time, short of the runway by about 160 m to 200 m (about 525 to 650 feet), according to reports. Locals immediately began to rescue the passengers and crew on fishing boats. Officials arrived after about ten minutes, according to a witness quoted by The Guardian.

In an interview, a passenger alleged the crew started panicking and yelling, The Guardian reported. A first responder, Dr James Yaingeluo, also said the airplane crew were in panic. He said, “There was a little bit [of] chaos at first because everybody was really panicked and tried to get out of the plane […] other than that we were doing as much as we can. Luckily there are no casualties.”

Yaingeluo said nine people were taken to a hospital. Four people remained in hospital, one “seriously injured”, according to reports recounted by ABC News on Friday evening.

Flight 73 was coming from Pohnpei in the Federated States of Micronesia. Its destination was Port Moresby in Papua New Guinea, with a stop at the Chuuk state.

United States Senator Ted Stevens of Alaska has been indicted by federal grand jury on seven criminal counts for making false statements in his Senate financial disclosure forms. The longest-serving Republican in the Senate, Stevens is the highest-profile politician ensnared in the corruption scandal surrounding VECO Corporation and its executives’ attempts to influence politics.

VECO, a subsidiary of CH2M Hill as of September 2007, is an oil pipeline and services company. It is alleged to have funded renovations to the Stevens home in Girdwood, Alaska in 2000. The renovations include a new garage and first floor, a two story wrap-around deck, as well as new wiring and plumbing. In 2007, VECO chief executive Bill Allen pleaded guilty to charges of extortion, bribery, and conspiracy.

The 28-page indictment alleges that Stevens “knowingly and willfully engaged in a scheme to conceal” gifts from VECO, which totaled “hundreds of thousands of dollars worth of things of value.”

A press release was issued by Stevens’ office in response to the allegations: “I am innocent of these charges and intend to prove that.” And Stevens himself commented, “I have never knowingly submitted a false disclosure form required by law as a U.S. senator.” Senator Daniel Inouye, a close friend of Stevens, commented: “As far as he’s concerned, he’s not guilty. And I believe him.”

Stevens was reportedly caught unawares on Tuesday when the indictment charge was filed. “Apparently, the media knew about it before he did,” Inouye stated, adding that he had just talked to Stevens. Ted Stevens was in a meeting with other Republicans when he found out about the charge.

Stevens is the longest-serving Republican senator in history and is up for reelection this November. Calls to his office in Washington for comment were redirected to a voicemail indicating that his “office is closed.”

The United States Department of Justice says it has already obtained seven convictions in the case: Peter Kott, a former Speaker of the Alaska House of Representatives; Thomas T. Anderson, a former state representative; Victor H. Kohring, another representative; James A. Clark, chief of staff to the former governor of Alaska; William Bobrick, a lobbyist; Bill Allen, VECO chief executive; and Richard L. Smith, VECO vice president of government relations.

Grand Ayatollah Ali Khamenei, Iran’s highest-ranking religious and political leader, blamed the intelligence services of the United States and Israel for the bombing of the Askari Mosque in Samarra, Iraq. According to him,

On 13th of June 2007, Iraqi insurgents blew up the two minerets of the Askari Mosque. The shrine is important because it contains the remains of the Imam Hadi and Imam Askari. The son of Imam Askari is Imam Mahdi. This is especially important in the context of Iran’s politics; according to Article 5 of the Constitution of the Islamic Republic of Iran, Khamenei as an Islamic jurist is supposed to lead the “Ummah“. Some Muslims object to this. For instance, one Islamic cleric has said that Khamenei “does not have a divine authority or right to determine the fate of other peoples and countries,” referring to Muslims outside Iran.

Khamenei urged Sunni scholars to speak out against the sacrilege and Shia Muslims to remain calm. He believes that this bombing of part of a conspiracy to fuel sectarian tensions.

Earlier, Sheikh Mohammad Hussein Fadlallah in Lebanon also made the same charge and said, “Without doubt, the occupiers are providing the grounds for Salafi Takfiri groups and intelligence agencies to pillage the country.”
