Cleveland, Ohio clinic performs US’s first face transplant

Thursday, December 18, 2008

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.

GitHub blocks public access to youtube-dl after RIAA issues DMCA notice

This article mentions the Wikimedia Foundation, one of its projects, or people related to it. Wikinews is a project of the Wikimedia Foundation.

Monday, October 26, 2020

On Friday, code hosting and sharing website GitHub blocked the public access to youtube-dl, a software which can download videos from the internet via the command-line. The blockade came after GitHub received a Digital Millennium Copyright Act (DMCA) take-down notice from the Recording Industry Association of America (RIAA). After stripping the metadata from the notice, GitHub published the take-down notice on their site.

Initially started in July 2008 by Ricardo Garcia, youtube-dl is a script written in Python which can download videos from multiple websites including YouTube, LiveLeak and Vimeo. youtube-dl is a FLOSS software and is under public domain. Currently, the repository on GitHub is locked for viewers other than maintainers of the project.

RIAA’s DMCA notice alleged the script’s purpose of existence was to “circumvent the technological protection measures used by authorized streaming services such as YouTube” and “reproduce and distribute music videos and sound recordings owned by our member companies without authorization for such use”.

youtube-dl has multiple unit tests in its source code, which test whether the software works in different circumstances or not. Some of the tests include checking if the script can download Creative Commons licensed videos, videos which did not have square pixels, videos with no age restriction, “offensive to some audiences” per YouTube community and age-restricted videos. One of the tests included the URL of some copyrighted songs. Citing this test, RIAA’s take-down notice claimed “comments in the youtube-dl source code make clear that the source code was designed and is marketed for the purpose of circumventing YouTube’s technological measures”.

RIAA’s notice published by GitHub alleged violation of 17 U.S. Code § 1201 Circumvention of copyright protection systems which says “No person shall circumvent a technological measure that effectively controls access to a work protected under this title”. RIAA listed a number of forks of youtube-dl and requested GitHub via the notice they all be made inaccessible.

The notice did not list any incident of anyone using youtube-dl to download or share copyrighted material, nor mention any damages that actually occurred. Unremarked by the notice, YouTube allows videos to be licensed under a Creative Commons Attribution license. When a copyright holder chooses to release their work, be it a photograph, a video, or audio, under a Creative Commons Attribution (CC BY) license, they allow everyone to freely own, share or modify the work as long as the reusers properly attribute the author of the work. YouTube also hosts many audio and video recordings in the public domain which can be used for any purpose without any restrictions.

youtube-dl is used by thousands of people around the world. Multiple Creative Commons-licensed and public domain videos on Wikimedia Commons are uploaded via a tool called video2commons, which relies on youtube-dl to download media. youtube-dl also lets users download videos from LiveLeak — a video-sharing platform for citizen journalism. Videos downloaded using youtube-dl are also used for the purpose of fair use, or for evidence.

youtube-dl comes with a small JavaScript interpreter where it acts as a web-browser would behave while receiving video data from the server. The script has “extractors” for various websites to handle videos from different sources. Whenever something is displayed on the user’s screen, the device has a copy of that content. Web browsers “download” data while surfing the web, though most of it is not persistent on the device. It is possible to download copyrighted photos by using a web-browser. The way the world wide web works, there are no technological prevention measures to prevent recording and sharing of content such as RIAA talks about in the notice. Photos and texts can be downloaded by taking screenshots, videos by screen recording tools, and audio by recording on a tape if not an audio recording software.

Multiple users expressed their disappointment on Twitter and Internet Relay Chat. One of the users said “this is yet another example of why we should use git as it was intended, as a distributed network, rather than rely on one single proprietary server”. Git is decentralised version-tracking software which is used by a large number of software companies and projects. It is possible to host one’s own git server for software development. While Microsoft’s GitHub is a centralised git server, development of software using git does not require a GitHub account.

Soon after the public access to the repository was locked, multiple users started sharing the source code via self-hosted git servers, Tor sites and via the Torrent protocol leading to a Streisand effect. Streisand effect is when a measure to censor information causes further spread of that information. The binary files of the software are still available on its website for users to download. Some people came up with esoteric ways to share the source code, by converting the compressed code into photographs and providing shell commands to convert to the source code.

GitHub’s DMCA repository, where the takedown notice was published for public viewing, was subject to contant vandalism from multiple GitHub users. One user submitted a pull request, merging the source code of youtube-dl along with the DMCA repository. This enabled users to view youtube-dl’s source code from within the DMCA repository, provided they know the commit id.

The Electronic Frontier Foundation said on Twitter “Youtube-dl is a legitimate tool with a world of a lawful uses. Demanding its removal from Github is a disappointing and counterproductive move by the RIAA.” Richard Stallman, the founder of the Free Software Foundation, has been highly critical of DRM (digital rights management, the subject of the DMCA) for many years now.

Wikinews reached out to Sergey M?, one of the maintainers of youtube-dl script, however Sergey said he “won’t give any comments at this time”. Later, he shared an update on the IRC channel. Sergey said, “they require complete removal of so called YouTube’s rolling cipher implementation […] GitHub requires in order to reinstate the repo […] under this conditions I could reinstate it in Saturday/Sunday already but this is an unsatisfactory outcome”. He also said, “I can’t guarantee whether [or] not we will bend over them considering the situation with @phihag [Philipp Hagemeister] but we’ll see soon what we can do in order to keep the max we have and mitigate potential legal issues at the same time”.

EFF is yet to respond to Wikinews queries. Wikinews also reached out to Philipp Hagemeister, a former maintainer and contributor of the youtube-dl project to discuss this takedown.

When did you get to know about the takedown notice and what were your initial reactions?

((Philipp Hagemeister)) I saw the takedown notice along with anyone else, on reddit. Since I am no longer involved with the youtube-dl project (except for occasional contributions, my maintainership ended in 2016), I don’t know any details.

((RS)) Does YouTube implement DRM for videos not under Creative Commons license, and if so, how does youtube-dl bypass it? Could you please elaborate the procedure?

((Philipp Hagemeister)) YouTube implements DRM for YouTube Movies. youtube-dl does not support those.

YouTube has multiple non-DRM video delivery protocols. I’m not up to date about specifics; my last dabbling in this was in 2015.

One of these protocols is described here. YouTube uses JavaScript to compute parts of the URLs. youtube-dl executes this JavaScript, just like a web browser.

((WN)) Could you also explain in brief how youtube-dl functions, and how the maintainers had intended it to be used?

((Philipp Hagemeister)) youtube-dl downloads and plays videos and music, just like any other web browser, from over 1000 different services. Its uses are varied: It enables video playback on many devices (e.g. Raspberry Pi) where the video services don’t work properly, it makes high-quality video playable for people with a bad or no Internet connection, it enables disabled users to use tools to play videos, and it is used for archival and research.

((WN)) What do you think of the DMCA notice?

((Philipp Hagemeister)) I think it is not warranted because youtube-dl is entirely legal. As the DMCA notice has no effect for me personally, I’m not really the right person to address it.

((WN)) Why were the copyrighted tests in the source code? Could they be replaced?

((Philipp Hagemeister)) I’m not sure why, but my guess is that users requested support for these videos and thus they were added as test cases. They can be removed trivially, without losing any function of youtube-dl.

((WN)) Are you aware Electronic Frontier Foundation said it was a “disappointing and counterproductive move”? What do you think should be the next steps?

((Philipp Hagemeister)) Yes, and I concur. I’m no longer involved in the project. If I were, I would probably just remove the test cases, block these music videos (RIAA is not worth the trouble for me, that can be done by other projects), and get the project back online.I understand people who think differently.

Japan to reduce aid to China

Wednesday, November 17, 2004

JAPAN — Japan’s Diet has proposed to reduce economic assistance given to China. Economic aid is currently given in the form of grants and technical assistance under the Official development assistance (ODA) program. ODA contributes to the development of the economies of states harmed by Japan during World War II, an approach pursued not only as restitution but to improve regional stability and to secure scarce natural resource trade.

Assistance to mainland China will total $8.9bn this year, making Japan an unusual second to the United States in aid. This is down 30% from 1997, and is the fourth year-on-year decline as of 2003. Loans to China total $30bn to date.

The ODA has been a key feature in Sino-Japanese economic and diplomatic relations. It was begun in the 1980s as China “opened up” to foreign investment. It is in part restitution for damage inflicted on China and atrocities such as the Rape of Nanking, seen in Chinese culture in much the same way as The Holocaust is in Western culture.

China is increasingly being seen as a competitor, however. Popular opinion in Japan is also increasingly resentful of what is perceived as anti-Japanese sentiment in China. Some feel that China should be grateful for ODA funds and that it is not. China has also been criticized by Japanese Foreign Minister Nobutaka Machimura for not being sufficiently cooperative with regards to environmental issues, which necessarily affect its eastern neighbor Japan.

The People’s Republic of China’s Communist leaders have also been criticized for violating w:human rights and effecting a military build-up. Some argue that economic aid should be tied to compliance on relevant standards.

Through the ODA, Japan enjoys the support of many developing nations in UN votes. When China did not react favorably to Japan’s intention to seek permanent UN Security Council membership, The Japan Times criticized the aid as a “complete waste”.

Asia Times Online predicts “it is inevitable that funds flowing to China are set for further downsizing.”

Total Japanese expenditures on ODA have reached $221bn distributed to 185 nations. Currently, the biggest recipient of Japan’s ODA aid is India. Japan may soon be outspent in aid to China by France, Germany and Italy.

Choosing A Wheelchair

Submitted by: Scott Miller

When looking to buy a wheelchair, probably the most important feature is comfort. It is also important to try out the wheelchair and make sure it fits and you are comfortable on it, as well as in it. Looking for the wheelchair that is right for you, might start to get long and tedious, but with the variety of models that are out today, you should be able to find one that suits all of your needs. When looking at wheelchairs, think about how you spend your day and what sorts of tasks you do, this will help to pick out the chair that will best fit you. If you need to transfer yourself, it is optimal to buy a chair model that is able to change heights.

Apart from what you will be doing with your wheelchair, it is also important to consider that type of environment that you will be using your chair in. Will you be traveling a lot outdoors in your wheelchair? Or will you being using it indoors only? If you decide that you will need to use your chair outdoors, you will be better off picking a model that is powered. This will help to give the wheelchair more power to move you in different types of outdoor environments. It is also safer to use a wheelchair with a motor when going outdoors. You will also need to have access to a vehicle that is wheelchair accessible. If you do not already have one, make sure to have arrangements before hand and that the wheelchair will fit inside the vehicle.

Having a wheelchair is not just a way for someone who is disabled to get around, it is a way of life. People who are confined to a wheelchair, need their chair to be comfortable, accessible, and also easy to use is important. When buying a wheelchair, it will help to make your lifestyle more active and help to keep you more independent, so you do not have to always rely on another person.

There are many different types of wheelchairs available today. The standard type of wheelchair is one that is manually operated and is best for those who suffer from only temporary injuries and for those that require minimal use of their spine and/or legs for a short time period.

Electric wheelchairs are best for those who are permanently confined to a wheelchair. An electric wheelchair will be able to give you more independence and the ability to freely move around.

Wheelchairs come in a wide variety of different weights and sizes. Trying out many is common and will help to ensure the best fit for your body.

Regardless of the type of wheelchair you are looking for, either manual or powered, the most important criteria for buying one is comfort, independence, and functionality.

Wikinews’ overview of the year 2007

Monday, December 31, 2007

What would you tell your grandchildren about 2007 if they asked you about it in, let’s say, 20 year’s time? If the answer to a quiz question was 2007, what would the question be? The year that you first signed on to Facebook? The year Britney Spears and Amy Winehouse fell apart? The year author Kurt Vonnegut or mime Marcel Marceau died, both at 84?

Let’s take a look at some of the international stories of 2007. Links to the original Wikinews articles are in bold.

Weight Loss Surgery

Are You Ready For Weight Loss Surgery?

Are You Ready for Weight Loss Surgery?

by

John Trodey

Weight loss surgery is something that more and more Americans are turning to. The US is currently the fattest nation in the world and something has to be done about it. That\’s where weight loss procedures come in. But when it comes to these sorts of surgeries there are also a number of recovery options available, and it\’s these that must be taken into account.

[youtube]http://www.youtube.com/watch?v=o30MXIPPxU4[/youtube]

Main Types of Surgery — Lap Band — Duodenal Switch — Roux-en-Y Gastric Bypass — Sleeve Gastrectomy The Principles of Weight Loss Surgery The principles of weight loss surgery are either reduction or bypassing. Reduction is the principle of reducing the size of the stomach. If the size of the stomach is reduced then that means it can hold less food and take in fewer calories. If it can do this then it will stop the person from eating as they will feel full much faster. That means they will be physically stopped from consuming more. Over time the stomach increases as surgery recovery commences, but not so much as to jeopardize the benefits that are gained from this. Bypassing is another method that cuts down on consumption as it completely bypasses parts of the digestive system. This means that the energy and the calories are going directly into the digestive system and are not just sitting around doing nothing. It will cause the feeling of fullness to come much faster, and that\’s why those who undergo a surgery involving a bypass will find that they will lose weight. Surgery Recovery When it comes to one\’s recovery options much of them is just a case of waiting. Immediately after surgery there will almost certainly be some minor pain. This minor pain means will continue for a few days, however it will disappear after a while. Painkillers can be employed to help dull the throbbing. Invasive procedures will generally involve a few days stay in a hospital with an extra few months to resume all normal activities. In many cases, a drip inserted directly into the body may need to be used to get those important nutrients into the body. The reason a drip is used is because the digestive system will most likely be too fragile to resume its normal function for the moment. As for diet, this will vary depending on the procedure. It really depends on how invasive the procedure was and the type of procedure used. In the case of invasive surgeries the drip, as already mentioned, will be employed for the first few days. After this it will come down to liquid foods with a small amount of solids. Lap bands decrease the stomach size by so much that liquid food is the only way to actually eat as initially the pouch will be about the size of a walnut. Over time, as the body recovers, more and more solid foods will be implemented into the diet to help with recovery after weight loss surgery.

Having a slimmer body makes many aspects of your life easier and also improve your self esteem.

Report reveals Top 10 most-confusing tech buzzwords

Sunday, March 27, 2005

Danville, California — The California-based Engligh language tracker, Global Language Monitor, released its 2005 list of most confusing – yet frequently cited – high tech buzzwords to be “HTTP,” “Voice Over IP” (VoIP), and “Megapixel.” Closely following were “Plasma,” “Robust,” “WORM” and “Emoticon.”

In early March, the group used a predictive index computer algorithm to track specific words and phrases in the media and on the Internet. They were tracked in relation to frequency, contextual usage and appearance in global media outlets.

The Global Language Monitor claims to analyze and catalogue trends in word usage and word choices, focusing on the linguistic impact on various cultures. The GLM says it relies upon a global network of volunteer linguists, professional wordsmiths and other bibliophiles to monitor the trends in the evolution and demise of world languages.

GLM’s list, in order of frequency of use, of the most-confusing technology terms with the group’s explanation as to why they are faulty follows:

  1. HTTP – HyperText Transfer Protocol is the standard protocol used for transmitting web pages (which are written in HTML (HyperText Markup Language)), not text written while hyper on too much Starbucks coffee. There are more than 1 billion references to HTTP on the web alone.
  2. Voice over IP – Voice over Internet Protocol, (pronounced voyp, similar to Detroit) is a way of transmitting voice data over the Internet. VoIP is becoming more popular as services such as Skype offer people free voice communication with anyone with a broad-band connection.
  3. Megapixel – Approximately one million pixels, not a single, big pixel (“mega” is the metric system prefix for million). “Pixel” itself is a technical term which means “picture element”. Digital pictures consist of a grid of millions of pixels, which are square or rectangular dots, each having a single colour.
  4. Plasma – A plasma display (commonly used in televisions) is a flat, lightweight surface with a grid of millions of tiny glass bubbles containing plasma. A digitally controlled electric current flows through the bubbles causing the plasma inside to glow various colours. Plasma displays have nothing to do with blood plasma.
  5. Robust – Robustness generally means “it won’t break easily.” It supposedly describes computer programs or hardware that have been well-tested and demonstrated to not crash or fail often, but since it is a vague term by nature (how robust is robust?) it is frequently used by marketing types regardless.
  6. WORM – While a worm is a type of computer virus, WORM stands for ’Write Once, Read Many’. It describes a file system primarily used for optical disks, such as CDs and DVDs. For example, CD-Rs can only be written (or “burned”) once but afterwards can be read many times (otherwise you could only listen to your music CD once). This excludes re-writable CDs which can be written many times.
  7. Emoticon – Emoticon stands for emotional icon. An emoticon is a sequence of characters that look visually like a face and are used in text chat to convey emotion. The most common emoticon is the smiley face – 🙂 – which looks like two eyes and a mouth turned 90 degrees.
  8. Best of Breed – Not to be confused with the Westminster Dog Show, a best-of-breed product is a personalized solution made of components from various manufacturers; in other words, it’s a sort of high tech ‘mix-and-match’.
  9. Viral Marketing – A recent marketing trend which relies on word-of-mouth to spread, rather than traditional advertising strategies. It is called “viral” because as people talk about it, the marketing message “spreads” to new people, who in turn inform others, and so on, which is how viruses spread. The Burger King “Subservient Chicken” campaign is considered an example of viral marketing. Computer viruses used by spammers to turn desktop computers into “zombie” spam relays are something completely different.
  10. Data Migration – Data migration is an idealistic (though usually impossible) concept where data can be used by different versions of the program in which it was created (newer or older). The migration (migration means “to move”) refers to the fact that the data is moved from one version (or program) to another without difficulty or loss of information. It is a subset of backward and forward compatibility.

Other terms being tracked included “client/server,” “solution,” “paradigm,” “backward compatible,” and the “STUN protocol.”

Neanderthals ‘knew what they were doing’: Archæologist Dr Naomi Martisius discusses her findings about Neanderthals’ behaviour with Wikinews

Sunday, June 28, 2020

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.
