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.

Officials from France’s aviation accident investigation agency, the Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA), announced on Tuesday that they had recovered the cockpit voice recorder (CVR) of Air France Flight 447. It was located and brought to the surface by a Remora 6000 unmanned submarine, then taken aboard the Île de Sein, one of the vessels taking part in the recovery and salvage efforts.

This came two days after an announcement on Sunday that the crash-survivable memory unit of the flight data recorder (FDR) of the aircraft had been located and brought to the surface. The chassis of the FDR was located on April 27, with the memory unit missing. It was found a short distance from the chassis. It was also brought to the surface by the Remora 6000.

With the recovery of both recorders, which are reported to be “in good condition”, French officials hope to determine what caused the Airbus A330-200 to crash into the Atlantic Ocean on June 1, 2009, when it departed Rio de Janeiro’s Galeão International Airport before it was lost 600 miles (965 km) off the coast of Brazil en route to Paris’ Charles de Gaulle Airport with 228 passengers and crew on board.

The leading theory at the moment is that the crew received incorrect air speed readings from the aircraft’s pitot tubes, devices which measure how fast the aircraft is traveling. Experts say the tubes may have become iced over, causing the crash. The plane’s Aircraft Communications Addressing and Reporting System (ACARS) sent out 24 messages over a four-minute long period stating numerous problems and warnings, including incorrect air speed warnings occurring aboard the aircraft, just prior to it going down.

However, chief operating officer of the International Bureau of Aviation, Phil Seymour, speaking to CNN, believes the memory unit will not be of much use to investigators saying because of the depth it was located at, “If you were to throw a computer into the ocean, imagine how all the parts would eventually split and you have the corrosive effects of seawater and the depths involved.” Seymour believes the wreckage will help reveal what happened as more is recovered.

“It may be that the more wreckage they find will help them to piece it all together, which bit by bit could help them build a picture of what caused the plane to come down,” he added.

A BEA spokesperson had agreed with that possibility a few days earlier when speaking to the Associated Press about the recovery of the flight data recorder. “We can’t say in advance that we’re going to be able to read it until it’s been opened,” the spokesperson said. As

The wreckage of the Airbus A330-200, was found back on April 8 at a depth of 3,800 and 4,000 meters (2,070 to 2,190 fathoms or 12,467 feet and 13,123 feet), by a team from the Woods Hole Oceanographic Institution, using a Remus robotic submarine and its side-scan sonar. After the wreckage was found, another Remus robot submarine with cameras was sent down to the site, where it filmed bodies in the wreckage. The location of the recorders were localized within 2 square miles (5 square kilometers) of the flight’s last position last year.

In March, a French judge placed the European aircraft maker Airbus and Air France under investigation for possible involuntary manslaughter charges in the 2009 crash. Both are paying the cost of the search which is estimated to be $12.7 million (nine million euro). The crash is the deadliest in Air France’s history.

The Brazilian President Luiz Inácio Lula da Silva met the leaders of Colombia, Venezuela and Spain, in Ciudad Guyana, 500 km (311 miles) from Caracas, in Venezuela, Tuesday, March 29.

The regional summit aimed to improve the diplomatic relations between Colombia and Venezuela, that had been shaken after the arrest of the FARC communist member Rodrigo Granda, in December, last year.

The following leaders were present at the meeting: the President of Colombia, Álvaro Uribe Velez; the Spanish Prime Minister, José Luis Rodríguez Zapatero; the President of Venezuela, Hugo Chávez; and the President of Brazil, Luiz Inácio Lula da Silva.

During the summit, the Brazilian president defended the Venezuelan President Hugo Chávez and he criticized indirectly the government of the United States for his opinions in relation to Chávez. According to Lula, South America is capable of taking care of its own problems.

Lula said: “We do not accept defamations against our “companheiros” (comrades). We do not accept insinuations against comrades. Venezuela has the right to be a sovereign country, to take its own decisions”. Lula also added that he is not afraid of doing this affirmation in “any place of the world”.

The US Secretary of Defense, Donald Rumsfeld, was in Brazil on March 22 and he said that he was very worried about the political situation in Venezuela. Venezuela is buying weapons and warlike material in great quantity and Washington is considering the country a harmful influence in the region. Recently Venezuela announced that it would buy 100,000 AK-47 rifles.

Lula also said:”I believe that Venezuela has the right to be a sovereign country, of making its own decisions and, at the same time, Venezuela does not need to be accused of things that those who are with you know that this is not part of your thought nor of your behavior.”

“There is^[sic] many people talking badly about us in the world”, he added.

The Venezuelan President did a calmer speech for the US: “We are not here to cause problems to anybody, for any reason. We were called to form this new geopolitical map, without confrontation with nobody (…) because it is convenient for us and all: it is convenient for the investors, for international businessmen, for national businessmen and for the United States themselves.”

Chávez and Lula both denied any involvement between their governments and the FARC guerrilla.

The Spanish Prime Minister, José Luis Zapatero said: “This is a meeting for the dialogue and the cooperation between free and democratic nations that want the advance of their people”.

Some say history tends to repeat itself. Today marked a day in history, when 20 years ago, the United States Dow Jones Industrial Average market crashed, on what is known as ‘Black Monday‘. The crash sent the market tumbling down 508 points, losing nearly 24%. On Friday, the Dow Jones nearly broke that record when the market closed at -366.94 points, down almost three percent.

Several factors could be to blame for the loss, one being Turkey’s government approving a measure on October 18 to send Turkish troops into Iraq in an attempt to take out militants of the Kurdistan Workers Party (PKK). This sent oil prices skyrocketing to the highest prices in history, with the highest record being just over US$89.00, which was set on October 18.

Fears that the housing market in the U.S. has come to a standstill has also lead Caterpillar Inc., which manufactures and sells construction equipment to issue a warning that the standstill would cause profits to drop, and the American economy to be severely hurt. On Friday their stocks lost nearly six percent to close at $73.57.

Investors and experts of the markets are disturbed by the losses calling the situation ugly.

“It’s pretty ugly. A company like Caterpillar should be a poster child for global growth and benefits of the weak dollar. It makes you question: Is global growth really that strong? Has the earnings kick from the weak dollar played itself out?” said Bell Curve Trading chief strategy expert, Bill Strazzullo.

Others believe that the losses were a way of emotionally responding to the events of ‘Black Monday.’

“Some of the earnings reports were a little disappointing but not that bad. I think we’re responding emotionally to the 20th anniversary of the October 1987 stock market crash. I’d like to laugh except it hurts,” said T Rowe Price Head trader, Andy Brooks.

The NASDAQ also took heavy losses to close down 74.15 points or -2.64%, closing at 2,725.16. The S&P 500 was also hit hard, losing 39.45 points, or -2.56%, closing at 1,500.63.

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.
