Crowd in Derbyshire, UK, encourages teenager to commit suicide

Sunday, October 5, 2008

It has recently been made public that on September 27, seventeen year old Shaun Dykes jumped off a multistory building following encouragement from the crowd. According to the BBC’s Today programme, a variety of different people, including youths and middle aged citizens, were telling the teenager to jump.

Alasdair Kay, director of the Derby City Mission, saw the incident unfold. He expressed his shock and disgust at the incident. “People were filming… we could hear people shouting ‘[J]ump, you,'” she said. “They weren’t all just young people, some were middle-aged. To be honest with you I was sickened.”

Derbyshire’s Chief Constable Mick Creedon, also yesterday commented on the indent. “The tragic death of Shaun Dykes at Derby on 27th September has attracted much comment and media speculation,” he started. “The pain that Shaun’s family and friends are suffering must be unimaginable and they have my deepest sympathy.”

“The primary responsibility of the police is the protection of life, and the Derbyshire Constabulary will always have this responsibility at the forefront of our response to such tragic events as Shaun’s death last Saturday,” he continued. “We have very well trained and experienced staff, well practiced in dealing with such incidents and I have no doubt that the officers involved in talking to Shaun on Saturday did their best with the situation they were presented with.”

“The fact that they were unsuccessful in negotiating Shaun to safety will have been very painful for them, particularly for the two officers who spent two hours talking directly to him. They have my sincere thanks for their efforts as, I’m sure, they have the thanks of the vast majority of those reading this.”

Shaun Dykes, had been raised in a single parent family in a village near Derbyshire and he recently returned from a business course to study to become an accountant or a pilot.

Before his death, he was working part time in a local pub. Craig Doxey, his best friend, described Dykes. “He was always smiling and laughing about stuff. I think if it wasn’t for the crowd, Shaun would have got down and got some help from all his mates, work colleagues and the police.”

He went to Heanor Gate Science College, and he was openly gay. According to one of his friends from that school, Rebkha Minkley, “he always came in, in the morning with a smile on his face.”

According to the Today program, Dykes is believed to have left a suicide note before jumping off the building.

Highly preserved mammoth presents scientists with blood sample

Friday, May 31, 2013

An extremely well preserved woolly mammoth has been found by Russian scientists in Siberia, announced Wednesday.

The adult female was found with blood preserved still intact in ice cavities. When palaeontologists excavated the animal, blood flowed from the space below the animal’s abdomen.

The discovery was made on the Lyakhovsky Islands by scientists from the North-Eastern Federal University in Yakutsk, who estimated the animal’s age at 10,000 years.

The temperature of the ice at time of excavation was estimated between ?7 °C (19 °F) and ?10 °C (14 °F). This has led scientists to believe mammoth blood may contain some cryoprotectant, making it resistant to freezing.

Scientists are currently discussing the possibility of resurrecting extinct animals from their DNA.Along with blood samples taken from the site, scientists also discovered well-preserved muscle tissue described as the color of fresh red meat.

The scientists hypothesise the mammoth had fallen into a swamp or water, where she was trapped and eventually died. The remains are to be transported to Yakutsk and tested to ensure there are no dangerous diseases present.

Researchers said this mammoth is the best-preserved ever discovered.

Summary –

The PorcelainPlus Speedbit was specifically designed for drilling through hard surfaces such as porcelain tile, marble, granite and quartz along with ceramic tile, glass and mirrors.

Body –

Starting at the beginning, measure where you want your shower curtain rod or grab bar, and hold the item in place so you can mark the exact spots where to drill the holes. Have a helper check the level and placement, because you only get one shot at this.

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

Ideally, you will drill into a stud to provide the support you need, especially when installing a grab bar. If you don’t, the bar may pull out and someone could be injured. So grab your stud finder and crack a cheesy joke about it before locating the two-by-fours behind your shower wall.

Begin to drill through tile

drill through porcelain tileUse a diamond drill bit and water containment unit for porcelain tile.

Once you’ve marked the holes, fill up the water containment piece, and keep a wrung-out sponge and bucket of water handy. Place the guide where you want to drill the hole, filled with water, and drill with a slow steady pull of the trigger, nice and easy at first, until you feel the bit grab the tile.

I usually pump the bit out and back in every 6 seconds so the water can cool it. Be sure the containment unit holds water the whole time. Take your time and keep drilling steadily until you feel it give and know you’ve pushed through the tile.

Repeat this process patiently and consistently for all the holes you need, and then test fit the bar again to make sure you got it right.

Seal the shower tile holes

Next, dry off the area, including the holes, and get your silicone ready. It’s extremely important to fill the holes with clear silicone before you screw the bar in. You want to maintain the waterproofing in the shower.

drill through porcelain tile

Fill holes in your tile with silicone before installing a shower curtain rod or grab bars.

I also like to put a bead of silicone where the bar attaches for extra support and water resistance.

Keep a rag handy, because silicone is not water-soluble and will make a real mess if it drips where it shouldn’t. Mineral spirits, however, can clean up silicone before it dries.

Once you have filled the holes and applied the silicone, you can screw in your bar. Don’t over tighten it or you could crack the tile. Screw it in just enough to hold firmly. Once you have all your screws in, give it a little tug to ensure it’s solid. Let the silicone cure for 24 hours before use.

If you follow these guidelines, you’ll have a secure grab bar or shower curtain rod, and you will finally be able to use that beautiful new shower.

Baby in California born with 12 functioning fingers and toes, in a rare case of polydactylism

Tuesday, February 3, 2009

A six-pound infant born in San Francisco, California has six perfectly formed and functional fingers and toes on his hands and feet, so that it isn’t considered a disability or deformity, say doctors at Saint Luke’s Hospital who were amazed by the oddity.

In a medical rarity, super baby Kamani Hubbard was born two weeks ago with 24 working digits. He is healthy and home with his parents in Daly City, California. Polydactyly, a congenital disorder is not uncommon in humans and animals, including cats, but to happen on both hands and feet is a rare hereditary condition.

“Nurses and doctors, looked so normal they couldn’t tell, they told me he was six pounds in good health, that was all they said,” said Miryoki Gross, Hubbard’s mother. Her baby’s specialness didn’t even show up on prenatal ultrasounds. “I heard nothing before I gave birth so I’m still in shock, kinda,” Gross added. Despite the mother’s shock, Kamani’s father, Kris, was the first to notice the condition.

Polydactyly (from Ancient Greek means ‘?????’ (polus) or “many” + ‘????????’ (daktulos) “finger[s]”), also known as polydactylism, sexdactyly, hexadactyly, or hexadactylism, is a congenital physical disorder consisting of supernumerary fingers or toes.

In Kamani’s case, however, all of the digits are perfectly formed and function or work normally. “I was in amazement, it took a little time for me to take it all in,” said Kris, a postal worker, who has a family history of polydactylism, but none of his relatives can remember it happening on both hands and feet.

Mostly, cases of polydactyly are surgically corrected. Kris himself had nubs of sixth digits, which were removed during his early childhood, for having been non-functional. “My son has six fingers then I saw toes, and I thought, this is quite unique. Some family members have had six fingers, not completely developed. But not the toes,” Kris noted.

“I would be tempted to leave those fingers in place. I realize children would tease each other over the slightest things, and having extra digits on each hand is more than slight. But imagine what sort of a pianist a 12-fingered person would be imagine what sort of a flamenco guitarist, if nothing else think of their typing skills,” Dr. Treece remarked.

“I just want him to see what greatness will be in store for him,” said Kris.

Fully developed and functional extra digits on both hands and feet are considered very rare as a genetic trait in medical history, amid some partial development of an extra digit occurs about twice in every 1,000 white male births. Ordinarily, polydactylism appears as an extra piece of non-functional tissue, typically occurring as an extra finger, sometimes with a bone, but no joint.

“It’s merely an interesting and beautiful variation rather than a worrisome thing,” said Dr. Michael Treece, a St. Luke’s Hospital pediatrician, and the OBGYN who delivered Kamani. He has postaxial polydactyly, which is 10 times more likely to occur in black children, and also more likely to appear in boys.

Goliath, a figure in Old Testament, was depicted as having had six fingers on each hand and six toes on each foot.

Blues guitarist Hound Dog Taylor, Get Carter, Little Tich, Toyotomi Hideyoshi and several other figures in history have had polydactyly. Sid Wilson, a turntablist of Slipknot, had been born with an extra finger and toe on his hands and feet which were removed shortly after his birth as doctors considered them to be dead.

Iconic London mural could be restored

Monday, September 20, 2010

One of London’s most well known murals could be restored after years of neglect if plans by a group of community activists gain public support. The Fitzrovia Mural at Whitfield Gardens on London’s Tottenham Court Road was created by two mural artists and commissioned by Camden Council in 1980, but the mural has since decayed and been vandalised.

Plans will be presented at a public meeting this Tuesday, to include details of the restoration and promote local public space in contrast to potential commercial developments and the focus of the London 2012 Olympics. If enough funds are raised from charitable trusts and public donations the mural could be restored during the summer of 2011.

Plans to be put forward by the Fitzrovia Neighbourhood Association, and the London Mural Preservation Society, will present ways to fund not only the restoration work but also projects to raise awareness of conservation, heritage, and the residential and working community. The heritage and mural project hopes to involve many local people who could learn new conservation skills. Also planned are workshops with local children to involve them in their heritage, an exhibition by local artists, guided tours and a celebratory event at the end of the restoration project. In addition to this, a booklet would be produced containing collected oral histories of the people involved and a preservation trust to protect the mural in future years.

The playful painting was created on a Camden Council-owned building in 1980 by artists Mick Jones, (son of the late Jack Jones, trade union leader) and Simon Barber and is a mash up of scenes depicting problems faced by the neighbourhood over the preceding decade.

There is also a caricature of poet Dylan Thomas, who lived in Fitzrovia, and a mocking portrayal of then leader of the Greater London Council, Conservative politician Horace Cutler, who is pictured as a bat-like creature. Other characters include an anonymous greedy developer and a property speculator counting piles of cash.

Peter Whyatt of the neighbourhood association is jointly leading the project to restore the mural. Yesterday he told Wikinews he had a number of concerns about the possible success of the project.

“There are a great number of problems with getting this project off the ground and we also need to act pretty quickly for a number of reasons,” said Mr Whyatt.

“Firstly the mural is in a terrible state and deteriorating quickly. There is more graffiti being daubed on the site every month because one bit of graffiti attracts another bit. We really need to start the work in the next 12 months because going through another winter with the condition of the wall will causes more problems and inevitably more expense. We want to keep as much original artwork on the site as possible to keep the costs down. This is a big mural and it will be expensive to restore,” he continued.

“And that brings me to my second concern: cost. If we don’t get other community organisations on board to bid for money for this with us and to involve their beneficiaries and volunteers, it will be very difficult to secure the money needed. Money is very tight at the moment because to the current financial climate. We need to get support at this meeting on Tuesday and some firm commitments from people and organisations to get involved.

“Lastly there is a danger of a commercial development on the site. A public-private partnership to create a new art feature. Because of the existing mural’s subject matter – it mocks property speculators, and land developers, etc – a commercial scheme probably backed by a property developer would not want to restore the mural’s original message. They’d want some “good news” scheme, some greenwash idea that paints them in a positive light.

“However, despite these problems, Camden Council have offered to do a condition survey on the mural. This will save us a lot of money. But having said that there are five council departments to deal with to get permission for this restoration work, and they don’t always talk to each other.

“But if the public and local voluntary organisations show their support, we can make it happen,” Mr Whyatt concluded.

The mural restoration will be just one part of a year long project of heritage and conservation awareness-raising. “The project is not just about the mural but also wider plans to promote awareness of heritage and conservation in an area of London under threat from commercial development. In fact the bulk of the project is about the heritage and conservation and the mural is just one part of it, and the most visible because of its situation,” Mr Whyatt later added.

There will be a public meeting about the heritage and mural project at 7.30 pm tomorrow (Tuesday), at the Neighbourhood Centre, 39 Tottenham Street. The public can also comment about the proposals on the Fitzrovia Heritage and Mural website.

Professionals and students continue strike in New Delhi

Sunday, May 21, 2006

New Delhi — Almost 10,000 people marched to Jantar Mantar from Maulana Azad Medical College in an anti-reservation rally on Saturday. Doctors and medical students say they will continue to strike and protest, despite an appeal from the prime minister to call off their agitation.

Students from Delhi University and medical colleges around the capital, parents, lawyers, and accountants joined the striking medicos, under the banner of ‘Youth for Equality’.

The students and their supporters want total rollback of a proposed quota-hike for Other Backward Classes (OBCs) in elite educational institutions, and a review of the present reservation policy. “There are very less seats in the post-graduate streams compared to the undergraduate courses. Hence the reservation move will affect the future of majority students,” said student leader Praful Raj.

The students have support from many groups. They were led by the Youth for Equality, an AIIMS initiative, while United Students, a DU and JNU group, IIT alumni, RWAs (under the banner of United Residents Joint Action), Resident Doctors Associations from various government and private hospitals, Chartered Accountant’s Association, students from private universities like IP, and parents of agitating students also joined in.

Students from medical colleges in Rajasthan, Orissa, Gujarat, Punjab and Karnataka also took part in the rally. Students and doctors say the government has showed “scant regard to the sentiments of the students”, who have been protesting the proposed quota-hike for OBCs in elite educational institutions.

The students had appealed to Prime Minister Manmohan Singh to set up a non-political judicial committee to review the existing reservation policy and sought an audience with him to discuss the issue.

Chula Vista, California becomes model for blight control laws in the US

Tuesday, October 14, 2008

The San Diego, California suburb of Chula Vista has responded to the recent housing crisis with an aggressive blight control ordinance that compels lenders to maintain the appearance of vacant homes. As foreclosures increase both locally and throughout the United States, the one year old ordinance has become a model for other cities overwhelmed by the problem of abandoned homes that decay into neighborhood eyesores.

Chula Vista city code enforcement manager Doug Leeper told the San Diego Union Tribune that over 300 jurisdictions have contacted his office during the past year with inquiries about the city’s tough local ordinance. Coral Springs, Florida, and California towns Stockton, Santee, Riverside County, and Murietta have all modeled recently enacted anti-blight measures after Chula Vista’s. On Wednesday, 8 October, the Escondido City Council also voted to tighten local measures making lenders more accountable for maintenance of empty homes.

Lenders will respond when it costs them less to maintain the property than to ignore local agency requirements.

Under the Chula Vista ordinance lenders become legally responsible for upkeep as soon as a notice of mortgage default gets filed on a vacant dwelling, before actual ownership of the dwelling returns to the lender. Leeper regards that as “the cutting-edge part of our ordinance”. Chula Vista also requires prompt registration of vacant homes and applies stiff fines as high as US$1000 per day for failure to maintain a property. Since foreclosed properties are subject to frequent resale between mortgage brokers, city officials enforce the fines by sending notices to every name on title documents and placing a lien on the property, which prevents further resale until outstanding fines have been paid. In the year since the ordinance went into effect the city has applied $850,000 in fines and penalties, of which it has collected $200,000 to date. The city has collected an additional $77,000 in registration fees on vacant homes.

Jolie Houston, an attorney in San Jose, believes “Lenders will respond when it costs them less to maintain the property than to ignore local agency requirements.” Traditionally, local governments have resorted to addressing blight problems on abandoned properties with public funds, mowing overgrown lawns and performing other vital functions, then seeking repayment afterward. Chula Vista has moved that responsibility to an upfront obligation upon lenders.

That kind of measure will add additional costs to banks that have been hit really hard already and ultimately the cost will be transferred down to consumers and investors.

As one of the fastest growing cities in the United States during recent years, Chula Vista saw 22.6% growth between 2000 and 2006, which brought the city’s population from 173,556 in the 2000 census to an estimated 212,756, according to the U.S. Census Bureau. Chula Vista placed among the nation’s 20 fastest growing cities in 2004. A large proportion of local homes were purchased during the recent housing boom using creative financing options that purchasers did not understand were beyond their means. Average home prices in San Diego County declined by 25% in the last year, which is the steepest drop on record. Many homeowners in the region currently owe more than their homes are worth and confront rising balloon payment mortgages that they had expected to afford by refinancing new equity that either vanished or never materialized. In August 2008, Chula Vista’s eastern 91913 zip code had the highest home mortgage default rate in the county with 154 filings and 94 foreclosures, an increase of 154% over one year previously. Regionally, the county saw 1,979 foreclosures in August.

Professionals from the real estate and mortgage industries object to Chula Vista’s response to the crisis for the additional burdens it places on their struggling finances. Said San Diego real estate agent Marc Carpenter, “that kind of measure will add additional costs to banks that have been hit really hard already and ultimately the cost will be transferred down to consumers and investors.” Yet city councils in many communities have been under pressure to do something about increasing numbers of vacant properties. Concentrations of abandoned and neglected homes can attract vandals who hasten the decline of struggling neighborhoods. Jolie Houston explained that city officials “can’t fix the lending problem, but they can try to prevent neighborhoods from becoming blighted.”

CEO Robert Klein of Safeguard, a property management firm, told the Union Tribune that his industry is having difficulty adapting to the rapidly changing local ordinances. “Every day we discover a new ordinance coming out of somewhere”, he complained. Dustin Hobbs, a spokesman from the California Association of Mortgage Bankers agreed that uneven local ordinances are likely to increase the costs of lending. Hobbs advised that local legislation is unnecessary due to California State Senate Bill 1137, which was recently approved to address blight. Yet according to Houston, the statewide measure falls short because it fails to address upkeep needs during the months between the time when foreclosure begins and when the lender takes title.

British conductor Edward Downes and wife die in double assisted suicide

Tuesday, July 14, 2009

British conductor Sir Edward Downes and his wife Joan took their lives at a Swiss assisted suicide clinic on Friday, July 10, 2009, according to a statement from their family. Lady Downes, 74, was afflicted with terminal cancer, and Sir Edward, 85, was nearly blind with increasing hearing difficulties. These disabilities had forced him to give up conducting. Having no religious beliefs, the couple decided against holding a funeral.

The statement read, “After 54 happy years together, they decided to end their own lives rather than continue to struggle with serious health problems. They died peacefully, and under circumstances of their own choosing, with the help of the Swiss organisation, Dignitas, in Zurich.”

Many who knew the couple as friends said that Sir Edward was not terminally ill, but wanted to die with his wife, who he had been with for more than 50 years.

Sir Edward Downes’s children, in an interview with The London Evening Standard, said they escorted their parents to Zurich, and on that Friday, they watched in tears as their parents consumed “a small quantity of clear liquid,” and then proceeded to lie down together, holding hands.

“Within a couple of minutes they were asleep, and died within 10 minutes,” said their 41 year old son, Caractacus Downes.

Sir Edward was well respected in the operatic and orchestral worlds and was particularly noted for his performances of British and Russian music and of Verdi, conducting 25 of the composer’s 28 operas. He had a long association with the Royal Opera House, where he conducted for more than 50 seasons in succession. This did not stop him from refusing to conduct a series of performances of Verdi’s Nabucco there as he was “out of sympathy” with the adventurous production. His approach to conducting was similarly conservative. He wrote “The duty of a conductor should be to present… a faithful and accurate account of the composer’s music as he wrote it, disregarding any subsequent ‘interpretations’, ‘meanings’, or political agendas that may have been attached to it by others.”

It was on Friday, 28 September, 1973, that Sir Edward conducted the opening public performance at the Sydney Opera House, a staging of Prokofiev’s War and Peace by Opera Australia, of which he was musical director. Downes also served as chief conductor of the Netherlands Radio Orchestra and principal conductor of the BBC Philharmonic.

The family reported that Lady Downes “started her career as a ballet dancer and subsequently worked as a choreographer and TV producer, before dedicating the last years of her life to working as our father’s personal assistant.”

The Metropolitan Police have announced that Greenwich CID are investigating the circumstances of the couple’s deaths. Assisting a suicide is illegal in the United Kingdom.

Over 100 people who wished to die have made the journey from Britain to Switzerland to take advantage of the clinical services that Dignitas offers. British police have investigated many of the resulting deaths, but no family member has yet been prosecuted for helping relatives negotiate with Dignitas and travel to Switzerland. Debbie Purdy, a woman with multiple sclerosis, attempted last year to obtain a ruling from the English High Court that family members would not be prosecuted for helping someone use the service, and in particular that her husband would not be charged should she decide to use Dignitas in future. The court refused as it believed that such clarification is the responsibility of parliament and not the judiciary.

Last week the House of Lords rejected a proposal by former Lord Chancellor Lord Falconer to allow people to help someone with a terminal illness travel to a country where assisted suicide is legal.

Hobbies And Crafts

Submitted by: Tracey Morgan

Whether you re 99 or not even in double figures, many an hour can be passed indulging in a hobby or craft that you love. Not only does a craft have therapeutic benefits, it keeps your mind and creativity active and might even lead to a career, a profitable part-time enterprise or just a way of always coming up with inventive and unique gifts for people.

Pay a visit to your local art supplies store and you ll find much more than paints and brushes. You ll be confronted with an Aladdin s Cave of materials and tools to turn your living room table into a mini workshop or studio. One of the great things about taking up a handicraft as a hobby is that art shops really can take you from being a wide-eyed beginner to being a seasoned pro thanks to their stocks of difficulty-rated products.

The best way to start a new craft is to get a kit of some sort. These can be quite inexpensive and will usually include everything you need to put your toe in the water and see if you like that particular hobby. For example, a basic candle-making kit might include moulds, flaked wax, stearin (or stearic acid), dyes, wicks and perhaps even some scent. All you ll need to bring to the party is a box of matches.

[youtube]http://www.youtube.com/watch?v=MdRR6pP-s-A[/youtube]

As you become more confident in your craft, you ll probably grow out of kits and want to start experimenting a little. You ll then be ready to move on to purchasing individual craft materials and tools, building up your collection and replenishing consumables as you go. Suppliers like http://www.pullingers.com have all kinds of craft materials and equipment to help you learn and improve your skills. Once you ve mastered your candle making kit, for example, and got to grips with the science and the techniques, you might want to start making your own moulds, and buying individual bags of wax and trying out new decorative techniques and aromas.

If you really love hobbies and crafts and you have a genuine talent for it, you never know, you could make it pay for itself or even turn a profit. Craft fairs are superb way to get started and to gauge public opinion; family members and friends are not reliable critics. Fairs often take place in village halls, at flower shows and during civic celebrations, and others are weekly, monthly or seasonal events. If you take a little time to create an attractive store front and talk to potential customers, you could be surprised at your success so make sure you take a bit of surplus stock. And don t forget to get some business cards or leaflets printed as customers might want to become regulars.

Another way into the marketplace is to offer your goods to a local gift shop. With a sale or return arrangement, there s no risk to either party, and with the shop taking a cut of the ticket price, you might find the shopkeeper phoning you for more stock sooner than you think.

With a little more investment you could even set up an online store and really make your hobby work for you. Better still, try all three routes to really get your name around.

So whether you like to paint, model, decorate pottery, make jewelery or ornaments or want to try making something that has been buzzing around your head for months, have a root around an art supplies shop and get creative it might just change your life.

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.
