In a new study released by the Florida Museum of Natural History on Monday, scientists report spiky skulls evolved at least 25 separate times in different kinds of frogs. The survey was reportedly to be published in Proceedings of the National Academy of Sciences.

Lead author Daniel Paluh, a Ph.D. candidate at the University of Florida, said, “Superficially, frogs may look similar, but when you look at their skulls, you see drastic differences […] Some of the weirdest skulls are found in frogs that eat birds and mammals, use their heads as a shield, or in a few rare cases, are venomous. Their skulls show how strange and diverse frogs can be.”

Some scientists had previously suggested smaller frogs would tend to develop spiky skulls, but that is not what this study reports. Here, researchers evaluated CT scans on 158 different species. They found frogs that had similar ecological niches — meaning they either acquired food in the same way or defended themselves from predators in the same way — tended to develop skulls with similar grooves, spikes, or specialized jaw joints regardless of whether they were ancestrally related to each other.

According to the study, skulls with spikes, grooves or ridges — called hyperossification — often accompanied frogs eating very large prey relative to their own body size. The strong, spacious skulls would allow the frogs to have very big mouths with which to catch birds, rodents, reptiles and other frogs. Spikes sometimes coincided with venomous frogs. The researchers speculated the spikes make it dangerous for predators to hit the frog’s head, as the spikes would break venom sacs under the frog’s skin.

Other bone formations included projections resembling fangs or lower teeth that different species of frogs use for catching prey and fighting. Very few frogs have true lower teeth.

One of the study’s authors, herpetologist David Blackburn, told Discover Magazine the frequency of spiky skulls evolving in otherwise unrelated frogs suggested some deep pattern frogs fell into as circumstances arose: “Somehow, these frogs are turning on some ancient developmental machinery in their DNA.”

Since 1973, when frogs skulls were last comprehensively surveyed, scientists have documented enough new species to double the number known to humans. Also, modern techniques exploit CT scans, of which Paluh and his team made liberal use. The research was part of the oVert project, funded by the National Science Foundation, meant to comprehensively CT-scan over 20,000 vertebrate specimens from United States museums.

Two web sites purporting to sell tickets to the 2008 Summer Olympic Games due to open in Beijing, China on Friday have been the subject of lawsuits from the International Olympic Committee in United States courts in recent weeks. The web sites, beijingticketing.com and beijing-2008tickets.com, were designed to resemble official sites and often appeared above the official sites in Google searches, and scammed some victims out of up to US$50,000 each for tickets to events such as the Opening Ceremony and swimming, which were listed despite the official Beijing ticket web site stating that tickets to all events had sold out as of July 27. The sites are believed to have taken in millions of dollars in total.

Ken Gamble, a private investigator from Sydney, Australia, believes the sites are operated by Terance Shepherd, whom Gamble has been tracking for several years in relation to other fraudulent web sites selling tickets to events such as the FIFA World Cup. According to Gamble, Shepherd’s modus operandi involves setting up the fake web sites, overselling the tickets, and then failing to produce the tickets. “The story’s always the same,” Gamble said, “it’s an ‘unfortunate mistake’ or someone has ‘let them down’. They promise a refund, which never happens, and the credit companies end up paying all the refunds.” Shepherd owns a home in the London suburb of Blackheath, although authorities believe he is currently hiding in Barbados.

On Monday, beijingticketing.com customers received an email from someone named “Alan Scott”, claiming that the site’s ticket supplier had filed for bankruptcy. The email recommended that customers should contact their credit card companies to seek refunds “immediately”, and said that the company would set up a call centre to provide assistance to its customers. However, the site has been shut down and a phone number previously listed on it has been disconnected. The company’s address, in Phoenix, Arizona, was found to be an empty office space. Visa International has stated that victims who used their Visa card to pay should be able to get their money back, but it is not yet clear whether the same will apply to all customers.

In an attempt to speak with as many candidates as possible during the 2008 Canadian federal election, Wikinews has talked via email with Paul Arbour. Arbour is a candidate in Ontario’s Carleton—Mississippi Mills riding, running under the New Democratic Party (NDP) banner.

The riding is currently represented by Gordon O’Connor, a Conservative. The Minister of National Revenue, O’Connor is up against the NDP’s Arbour, Liberal Justin Mackinnon, and Green Jake Cole. Previous MPs in the riding were Progressive Conservative, Liberal, and Canadian Alliance members. A riding since 1988, Carleton—Mississippi Mills is in the Capital region.

The following is an interview with Arbour, conducted via email. The interview has had very limited editing, to eliminate in-text mentions of website addresses, but is otherwise left exactly as sent to Wikinews.

The government of Brazilian President Luiz Inácio Lula da Silva is in a severe political crisis. The crisis began after the exposure of a series of scandals which involve the Workers’ Party, the Brazilian ruling party.

In 2002, Celso Daniel, the mayor of Santo André, 10 km (6 miles) away from the São Paulo city, was murdered. Daniel was a member of the ruling Workers’ Party. The mayor’s brother says that Daniel died because he was in disagreement to a supposed bribe conspiracy organized by some Workers’ Party members. The case remains under investigation by police.

In 2004, the former adviser to the government of President Lula, Waldomiro Diniz, was accused of negotiating with “bicheiros” (men who deal with: “Jogo do Bicho”, or illegal gambling) and extorting money for Workers’ Party (PT) electoral campaigns. A supposed victim of extortion released a tape exposing Diniz. The tape’s authenticity has been verified by experts and it was aired by the major Brazilian television stations. A Congressional special commission was proposed by non-government parties so the denunciation could be investigated. The government succeeded in stopping the creation of the commission.

On March 16, the leading Brazilian magazine Veja published a story saying that according to documents of the Brazilian Agency of intelligence (Abin) the Workers’ Party received 5 million dollars to be used by political campaigns of their candidates in 2002 from the Colombian communist armed group Revolutionary Armed Forces of Colombia (FARC-EP). Abin said that the documents were not authentic.

Last month, some men, supposedly involved in illicit negotiations with the Brazilian Post Service recorded a video which shows former Post Office Chief, Maurício Marinho, during a supposed bribe negotiation. In the tape, Marinho receives and puts in his pocket R$3,000 (about 1,259 USD) in cash. He insinuates that the scheme is commanded by deputy Roberto Jefferson. The recording was aired by the major Brazilian television stations.

Roberto Jefferson is the president of the government-allied Brazilian Labor Party (PTB). Lula da Silva said in a earlier occasion that he “would give to Jefferson a bank check in blank”, what means that he had high confidence on Jefferson.

Still related to the Post Office case, on June 2, Lídio Duarte, the former president of IRB, a government enterprise, denied allegations that money from some Brazilian government enterprises was going to PTB, Jefferson’s party. An earlier story published by magazine Veja, said that Duarte was a victim of extortion by a representative of PTB. According to Veja, Duarte resigned from the Presidency of IRB, because he had difficulties in continuing to give more money to PTB. Lídio denied this story to the police, and furthermore he said that he never have had an interview with Veja’s journalists.

On June 8, the magazine Veja released for download in its webpage, an audio tape where it can be heard the voice of Lidio Duarte during an alleged interview to Veja. In the tape, Lidio Duarte talks about being under pressure because someone was asking him more contribution in money for PTB. The tape contradicts the Duarte’s testimony to the police and because of that, he became subject of investigation by the authorities. The name of the deputy Roberto Jefferson is cited by Duarte in the alleged recorded interview to Veja.

After the Post Office scandal been exposed, the Brazilian Congress proposed the creation of a Congress’ special commission, so it could be investigated by the Parliament. The government, however, protested against it, arguing that political adversaries were anticipating the dispute to the next election for Brazil’s Presidency. Workers’ Party senator Eduardo Suplicy protested in Senate against his party decision. Because that he was very criticized and he got subject to punishment by the Workers’ Party.

On June 6, Roberto Jefferson told the Brazilian newspaper Folha de São Paulo that the ruling Workers’ Party (PT) has payed Brazilian deputies 30 thousand Brazilian Reals (US 12 thousand) each, every month. The stock markets went down and the U.S. Dollar increased its value in relation to the Brazilian Real. A new Congress’ special commission was proposed by some Brazilian senators, so Jefferson’s allegations could be investigated. The Workers’ Party says that Jefferson’s allegations were untrue and that he had no proofs.

After Jefferson’s denunciation the focus of the scandal moved to the government and the ruling Workers’ Party. Because the government were under pressure, the Workers’ Party changed his earlier decision of stopping the creation of a Congress’ special commission for the Post Office scandal. The proposal for the creation of a Congress’ special commission for the Post Office scandal was approved.

On June 9, there was the first meeting of members of the Congress’ special commission for the Post Office scandal. Because of unsolved disputes between government’s parliamentarians and the other parties representatives, the meeting could not continue. The government’s block argued that it must choose the president and the report for the commission, since the government commission members are the majority. Other parties argue that according to Parliament tradition the government should choose one member for the presidency or report and the opposition should choose the other member.A new meeting was scheduled to the next week, on Tuesday, June 14.

Besides these scandals, the current Social Security Minister, Romero Jucá, is accused of havingoffered seven non-existent farms as guarantee for a financing from the Banco of Amazonia, among other denunciations of misuse of public loans. The current President of Brazilian Central Bank, Henrique Meirelles, is accused of financial fraud among other accusations. Also there is a denunciation of a irregular transference of founds of Central Bank to the construction of a new headquarter for the Workers’ Party.

On June 4, during the so called Curupira operation, the Brazilian Federal Police arrested members of IBAMA, a Brazilian agency for environment. Among other accusations, they are accused of selling irregular licenses for deforestation in Amazon. At least one of the suspects, a Workers’ Party affiliate, is under suspection of have used the money for the political campaign of a Worker’s Party candidate in Mato Grosso.

Besides the commission to investigate the Post Office scandal, another Congress’ special commissions were suggested by non-government members of Brazilian Senate: a commission to investigate the IRB scandal and another one to the investigation of Roberto Jefferson’s allegations. Also, it is expected that the Brazilian Courts rule against the earlier government decision of stopping the creation of a commission for the investigation of the alleged Waldomiro Diniz scandal.

Journalist, counselor, painter, and US 2012 Presidential candidate Joe Schriner of Cleveland, Ohio took some time to discuss his campaign with Wikinews in an interview.

Schriner previously ran for president in 2000, 2004, and 2008, but failed to gain much traction in the races. He announced his candidacy for the 2012 race immediately following the 2008 election. Schriner refers to himself as the “Average Joe” candidate, and advocates a pro-life and pro-environmentalist platform. He has been the subject of numerous newspaper articles, and has published public policy papers exploring solutions to American issues.

Wikinews reporter William Saturn? talks with Schriner and discusses his campaign.

The Pacaya Volcano erupted on Friday. It is located 50 kilometers south of the capital of Guatemala, Guatemala City. Throughout the evening and night, volcanic ash fell in the municipalities of Amatitlán, Villa Nueva, and Guatemala City.

President Álvaro Colom’s government has decreed a State of Public Calamity in the Escuintla, Sacatepéquez and Guatemala departments, for 15 days or more, so the authorities can do their job correctly. The emergency response is being coordinated by the National Coordination for Disaster Reduction (CONRED).

The eruption was followed by several tremors. All flights in and out of Guatemala City’s La Aurora International Airport, have been suspended. The eruption has caused many casualties, among them the death of Aníbal Archila, NOTI7’s reporter, who was one of the first reporting the event.

General Motors (GM) and Chrysler will receive bridge loans from the government of Canada and the provincial government of Ontario, however no more will be forthcoming from either Canadian or US governments unless the companies can reinvent themselves.

“This is a regrettable but necessary step to protect the Canadian economy. We are doing this on the assumption that we obviously cannot afford either in the United States or Canada a catastrophic short-term collapse.” said Stephen Harper, Prime Minister of Canada.

“We cannot, we must not, and we will not let our auto industry simply vanish. This industry is, like no other, an emblem of the American spirit; a once and future symbol of America’s success,” said Barack Obama, President of the United States. “These companies – and this industry – must ultimately stand on their own, not as wards of the state.”File:Sinsheim quer.jpg

Chrysler will receive CA$1 billion and may in fact be eligible for as much as CA$4 billion. If Chrysler succeeds in the next 30 days with a restructuring plan it would be eligible for a US$6 billion loan. A part of Chrysler’s restructuring plan must include a partnership with Fiat within 30 days to appease the US administration. Fiat is a supplier of smaller fuel-efficient vehicles, and the merger will help Chrysler to be viable in the North American market. A Chrysler court bankruptcy would inevitably lead to it being sold off.

As a part of Chrysler’s restructuring plans, Tom LaSorda, the president of Chrysler announced that Canadian operations would fold if it does not receive both the US commitment of $2.3 billion of aid and a new Canadian Auto Workers CAW contract to reduce all-in costs by CA$19 per hour. As a result of this announcement Chrysler’s auto sales volume in Canada dropped 23% compared to March of 2008.

GM has until the end of May to restructure its company to receive up to CA$7.5 billion. As part of the companies restructuring, General Motor’s chief executive Rick Wagoner was replaced Sunday with Fritz Henderson, the current chief operating officer. Henderson spoke out on Tuesday that GM has submitted a restructuring plan which would close five plants, and this may be increased to meet the requirements for financial aid. He is in full compliance with Obama’s auto task force to seek bankruptcy if GM cannot negotiate with their unions, bondholders and others.

GM recently brought forward the “GM Total Confidence” program providing consumer purchase protection for customers who lose their job for economic reasons within the first two years from purchase. As a result of Chrysler’s restructuring announcement in Canada, GM’s Canadian vehicle sales volume fell only 17.3% compared to 2008, an increase from the previous month.

GM must reduce some of its legacy costs which include its pensions and union health care costs. A part of GM’s ailments arose from investing in supplying truck and SUVs during an economy of high gas prices when consumers were demanding fuel efficient vehicles.

Tony Clement, Canada’s Minister of Industry, is hoping that the CAW will support the restructuring process and re-negotiate their agreement. Whereas a United Auto Workers negotiator has said, “I don’t see how the UAW will do anything until they see what the bondholders will give up.”

The Obama administration is looking toward bankruptcy proceedings for the automakers, “as a mechanism to help them restructure quickly and emerge stronger. [It will] quickly clear away old debts that are weighing them down. What we are asking is difficult. It will require hard choices by companies. It will require unions and workers who have already made painful concessions to make even more. It will require creditors to recognise that they cannot hold out for the prospect of endless government bailouts.” said Obama.

The auto parts suppliers and IT software exporters in India have already been affected by the declining auto sales. GM and Chrysler software contracts provide US$300 to 350 million a year to vendors in India. As well these two major automakers usually award US$1 billion contracts to auto parts suppliers. “We are worried and closely watching the developments in the US to gauge the impact. The decline in auto sales in the US has already hit the order books of Indian suppliers,” said a Delhi auto parts supplier.

“Going forward, the industry will undoubtedly be smaller, but if our efforts are successful it will be viable and it will support good jobs for Canadians,” said Clements.

Betty Sutton, Ohio’s Congresswoman put forward the CARS act which provides a US$3,000 to 5,000 incentive for those who trade in their vehicle for a fuel-efficient car. “It clearly stimulates the economy, and it gets the consumer into the showroom and gets them buying again. But importantly — and this is what I particularly like about it — it really helps the environment quite a bit in two respects.” said William Clay Ford Jr., executive chairman of Ford Motor Co.

Ford Motor Company has not come forward with requests for assistance.

Since December GM and Chrysler have received US$17.4 billion government loans.
