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.

The British Parliament approved the first stage of the new Crossrail underground railroad through London as a £15 billion construction project earlier this month. Crossrail is the first major new train line to be built in London in decades.

The rail line being implemented as a hybrid bill in Parliament. After a second reading in Parliament, it was voted upon and decided that the government will commit to the project so that the line will be built.

The next issue before Parliament of to ensure that the implementation of the bill so it is consistent with private interests of neighborhoods to be affected by Crossrail. This is when residents can petition Parliament to change the way the line is constructed.

As a result of construction of the Crossrail line, hundreds of homes will have new tunnels excavated beneath them.

On contacting Crossrail, they have indicated approximately £50 will be offered to each landowner to buy all the land rights-of-way to build the train tunnel more than 9 meters below the residential buildings. The average value for properties in the affected areas is £350,000.

Under UK compulsory purchase laws to be used in this bill, the residents are entitled to the difference in the value of the whole property with and without a tunnel under it. If the offer given by Crossrail is not accepted by any of the residents, the residents can take the case to the Land Tribunal, where the fair value will be established.

This however, could be cost prohibitive. Crossrail does not indicate that it will attempt to assign a fair value in the original offer and instead is only going to offer around £50 per property in the hope that not many people take the matter to the Land Tribunal.

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.

Friday, July 17, 2009Following similar threats by workers at New Fabris and Nortel, workers at JLG in Tonneins, France, threatened to blow up several platform cranes. The JLG factory announced in April 2009 that it will fire 53 of its 163 workers by the end of 2009, while the remaining 110 jobs will not be secure over the next 2 years.

JLG Tonneins was acquired in 2006 with its parent JLG Industries, a maker of aerial work platforms, by the U.S.-based Oshkosh Corporation. Despite being hugely profitable in the past, production has been much reduced since 2008 with the contraction of the construction industry and lower demand for its products. Despite excellent past results the new American management demanded sweeping cuts at the company.

In the view of locals, “the company’s actions are a disgrace given the expensive perks, such as official cars, for its corporate fat cats, compared to the sacrifice, silence, and dignity demanded by the company of those it has made redundant.”

The management offered severance pay of € 3,000 (US $4,200), however the workers demanded a severance package commensurate with “the wealth that their labor has generated.” Worker’s delegates requested a “supra-legal” payment of € 30,000, on Thursday 16 of July the management responded with a counter offer of € 16,000. On Thursday night the worker’s actions secured the € 30,000 settlement initially demanded.

Companies in the United States are shedding more jobs, pushing the country’s unemployment rate to a 26-year high of 9.8%.

The US Labor Department said on Friday that employers cut 263,000 jobs in September, with companies in the service industries — including banks, restaurants and retailers — hit especially hard. This is the 21st consecutive month of job losses in the country.

The United States has now lost 7.2 million jobs since the recession officially began in December 2007. The new data has sparked fears that unemployment could threaten an economic recovery. Top US officials have warned that any recovery would be slow and uneven, and some have predicted the unemployment rate will top 10% before the situation improves.

“Continued household deleveraging and rising unemployment may weigh more on consumption than forecast, and accelerating corporate and commercial property defaults could slow the improvement in financial conditions,” read a report by the International Monetary Fund’s World Economic Outlook, predicting that unemployment will average 10.1% by next year and not go back down to five percent until 2014.

Mark Zandi, chief economist at Moody’s Economy.com, said that “it’s a very fragile and tentative recovery. Policy makers need to do more.”

“The number came in weaker than expected. We saw a lot of artificial involvement by the government to prop up the markets, and now that that is starting to end, the private sector isn’t yet showing signs of life,” said Kevin Caron, a market strategist for Stifel, Nicolaus & Co.

Also on Thursday, the US Commerce Department said factory orders fell for the first time in five months, dropping eight-tenths of a percent in August. Orders for durable goods — items intended to last several years (including everything from appliances to airliners) — fell 2.6%, the largest drop since January of this year.

The US government has been spending billions of dollars — part of a $787 billion stimulus package — to help spark economic growth. There have been some signs the economy is improving.

The Commerce Department said on Thursday that spending on home construction jumped in August for its biggest increase in 16 years. A real estate trade group, the National Association of Realtors, said pending sales of previously owned homes rose more than 12 percent in August, compared to August 2008.

A separate Commerce Department report said that consumer spending, which accounts for more than two-thirds of US economic activity, rose at its fastest pace in nearly eight years, jumping 1.3 percent in August.

Other reports have provided cause for concern. A banking industry trade group said Thursday the number of US consumers making late payments, or failing to make payments, on loans and credit cards is on the rise. A survey by a business group, the Institute for Supply Management, Thursday showed US manufacturing grew in September, but at a slower pace than in August when manufacturing increased for the first time in a year and a half.

Stock markets reacted negatively to the reports. The Dow Jones Industrial Average fell 41 points in early trading, reaching a level of 9467. This follows a drop of 203 points on Thursday, its largest loss in a single day since July. The London FTSE index fell 55 points, or 1.1%, to reach 4993 points by 15.00 local time.
