US says Guatemalan lottery launders drug money (AP)

GUATEMALA CITY ? The U.S. Treasury Department says a popular private lottery in Guatemala is a front for laundering drug money.

The department's Office of Foreign Assets Control says it has designated Bingoton Millionario part of a drug-trafficking ring run by a 39-year-old woman.

It calls the woman, Marllory Dadiana Chacon Rossell, one of the most prolific traffickers in Central America. It says her organization moves tons of cocaine each month into Mexico and on to the United States.

The lottery's Facebook page says it sells tickets in thousands of stores across Guatemala and has awarded a total of $2 million to 595,000 winners over the last three years.

Guatemala's government says it will start an investigation based on Thursday's accusation by the U.S.

Biofilms: a house for protection or a tent for nomads

I?m currently off on my seriously-delayed honeymoon, so over the next two weeks I?ll be sticking up some posts I enjoyed from my old blog. They?ve been modified and re-edited to include new information (and images!) where appropriate, but unfortunately I won?t be able to answer comments or participate in any discussion about them until I get back.

Although bacteria live as isolated cells they are constantly communicating with surrounding bacteria, particularly those of the same species, and can often band together to form large groups of bacteria surrounded by a sticky mesh. These are known as biofilms (which I cover in more detail?here). One of the main ways that bacteria communicate with each other in order to organise structures like this is by quorum sensing.

Quorum sensing uses small molecules that bacteria can both excrete and sense. When enough bacteria are in one place then the surrounding concentration of these small molecules reaches a critical level and can activate the genes for a variety of different responses including luminescence, virulence (in pathogenic or disease-causing bacteria) and the formation of biofilms:

From "Looking for Chinks in the Armor of Bacterial Biofilms" Monroe D PLoS Biology Vol. 5, No. 11, doi:10.1371/journal.pbio.0050307 via wikimedia commons.

It turns out that there are a whole range of different types of biofilms, that bacteria use for many different purposes. Although many species formed biofilms when bany cells joined together some species?stopped forming biofilms when they reached a certain cell density. Biofilms are carefully controlled by bacteria, they do not just start growing when a certain number of bacterial cells gather together and then never stop, each biofilm is tailored specifically to the needs of the species making it.

Using models of mostly infectious biofilm-forming bacteria (such as?Vibrio cholerae which causes cholera) they found that as well as helping to bind the cells together and resist attacks from antibiotics the biofilm was also a defense against competing bacteria and may have helped to out-compete them by covering all available living surfaces with slime. The ability to produce biofilms not only helps the?V. cholerae against other invading bacteria, it also helps it gain a hold against the body?s own internal bacterial defenses that line the internal gut.

However once the levels of?V. cholerae became too high the bacteria often stopped generating the biofilms. This could be for two reasons, firstly the biofilm takes up valuable resources that could be used in growth and division and secondly it prevents the bacteria within it from travelling very far.?V. cholerae infect the body by having periods of growth followed by periods of mad colonisation, which works best if the biofilm actually disperses at high cellular density to allow the cells to spread.

This can be contrasted with more sedentary bacteria like?P. aeruginosa which likes to settle down once it finds a place to live and occasionally disperse colonies into the body. Rather than loosing its biofilm this bacterial species retains it even at high cell densities. This allows it to out-compete any other bacteria that may be at the site of infection, and hold off both the body?s natural defenses and any chemical antibiotic drugs meant to kill it.

Comparisons of different?V. cholerae strains revealed a wide range of different biofilm formation patterns between strains, all linked to Quorum sensing signalling. This is likely to depend on the internal environment that specific strains occupy, the amount of competition they face and the necessity for quick and frequent bouts of dispersal.

Biofilms are often seen as being a final living space, a giant bacterial ?city-base? from which offspring can spread while the old-timers stay and develop antibiotic-resistance to new challenges. It?s interesting to see that this is not always the case. That the biofilm can just as easily be a short-term shack for?travellers?as well as a city for settlers.

Japan's Fujifilm calls for Swiss-style yen (Reuters)

TOKYO (Reuters) ? Fujifilm Holdings President Shigetaka Komori wants a Swiss-style cap on the yen to help Japanese firms, he said in an interview on Wednesday, adding his voice to a growing chorus of executives including Nissan's Carlos Ghosn.

Komori also said diversification helped protect Fujifilm from meeting the same fate as photographic film pioneer Eastman Kodak, which is preparing a Chapter 11 bankruptcy filing in case it is unable to sell its digital patents to raise capital, a report said earlier this month.

Fujifilm, which diversified from the shriveling photographic film market into digital photography, printers and healthcare, in October cut its operating profit forecast for the financial year ending in March by 15 percent to 136.5 billion yen ($1.8 billion), blaming the strong yen and global economic uncertainty.

But Komori said that would amount to a record profit if calculated on the basis of 2007 exchange rates and materials prices.

"The government is showing weak leadership," he said. "We are asking the government to do something like Switzerland," Komori said, referring to the Swiss National Bank's cap on the franc at 1.20 per euro, introduced last September.

Japanese Finance Minister Jun Azumi, however, told reporters on Wednesday that it would be hard for Japan to set such an upper limit on its currency given the vast supply of yen in global markets.

"From the standpoint that the Japanese yen is basically the third key currency after the dollar and the euro, we cannot go as far as the Swiss have done," Azumi said.

Fujifilm's Komori sees 90 yen to the dollar as a fair exchange rate, compared with current rates of about 77 yen.

But he said Fujifilm could bear the current rates and that he currently had no plans to shift more production overseas.

Nissan's Ghosn said last November many projects were being moved outside Japan because businesses could not cope with current exchange rates. He called for a fixed exchange rate.

Komori lamented the fate of Kodak, with which it is currently engaged in a court battle over digital camera patents, as the U.S. firm also tries to sell its patent portfolio to secure enough funds to enable it to avoid bankruptcy.

"It's a shame. They used to be a strong rival," he said. "Kodak were not as well prepared as us for the digital era," he added.

Failure to develop a wide portfolio of businesses may also have weakened the U.S. company, whose name was once synonymous with photography, Komori said.

"Kodak said they just wanted to be a digital company. But that alone was not enough," he said, noting that Fujifilm has expanded into pharmaceuticals, medical and office equipment as well as films used in liquid-crystal display panels.

($1 = 76.8100 Japanese yen)

Markets shrug off S&P downgrades, focus on Greece (AP)

LONDON ? European markets responded calmly to Standard & Poor's decision to cut the credit ratings of a number of euro countries as France managed to tap bond market investors Monday despite the loss of its cherished triple-A rating.

The downgrades, which were based on concerns over Europe's ability to handle its two-year debt crisis and the lack of economic growth, had been anticipated for weeks so the market impact was muted, especially since the U.S. is on holiday for Martin Luther King Jr. Day.

Europe is set to remain the focus of attention all week as a number of bond auctions are due and Greece tries to clinch a debt deal with its private creditors. Last October, Greece's partners in the eurozone sanctioned a deal whereby Greece's creditors agree to take a cut in the value of their Greek bond holdings to help lighten the country's debt burden.

The deal with private investors, known as the Private Sector Involvement, or PSI, aims to reduce Greece's debt by euro100 billion ($126.5 billion) by swapping private creditors' bonds for new ones with a lower value. It is a key part of a euro130 billion international bailout, the second one for Greece.

It is expected that talks on the PSI will resume this coming week after being abandoned last Friday.

On Tuesday, representatives of Greece's creditors ? the European Union, the European Central Bank and the International Monetary Fund ? will visit Greece for yet another round of inspections of its efforts at fiscal and structural reform and negotiations for the next tranche of money, the seventh, from the first bailout.

Without a deal with its private creditors, Greece has been told it won't get the seventh tranche. Without that, Greece would be unable to pay a big bond redemption in March and face the prospect of defaulting on its debts, potentially triggering more mayhem in financial markets.

Gary Jenkins, a director of Swordfish Research, reckons the Greek debt restructuring poses more risks to the markets in the short-term than S&P's decision to strip France of its cherished triple A credit rating or to downgrade eight other euro countries, including Italy.

"The progress or otherwise of these negotiations will probably dictate how the market trades over the next few weeks," said Jenkins.

Greece's Prime Minister Lucas Papademos insisted in an interview with CNBC that a deal will be hammered out.

"Some further reflection is necessary on how to put all the elements together," he said. "So as you know, there is a little pause in these discussions. But I'm confident that they will continue and we will reach an agreement that is mutually acceptable in time."

While investors awaited developments, markets were trading modestly higher especially after France easily sold short-term debt to investors in the first auction since Standard & Poor's stripped the country of its top tier rating.

Meanwhile, there was further good news in the bond markets as yield on France's ten-year bonds was falling back toward the 3 percent mark, which is well within what is considered manageable.

In stock markets, France's CAC-40 closed 0.9 percent higher at 3,225 while Germany's DAX rose 1.3 percent to 6,220.01. The FTSE 100 index of leading British shares ended 0.4 percent higher at 5,657.44.

The euro was also steady, up 0.2 percent at $1.2675. On Friday, it had fallen to a 17-month dollar low of $1.2623 as speculation swirled in the markets of S&P's downgrades.

Earlier in Asia, markets responded more negatively to the S&P downgrades, which were confirmed after U.S. and European markets had closed on Friday. Asian markets had already closed by the time speculation of the downgrades emerged.

Japan's Nikkei 225 index slid 1.4 percent to close at 8,378.36 and Hong Kong's Hang Seng lost 1 percent at 19,021.20. South Korea's Kospi dropped 0.9 percent to 1,859.25.

In mainland China, the Shanghai Composite Index lost 1.7 percent to 2,206.19, while the smaller Shenzhen Composite Index dropped 3.3 percent to 818.17. Almost 70 companies plunged the daily limit of 10 percent.

In the oil markets, traders are fretting over simmering tensions in the Middle East and Nigeria ? benchmark oil rose $1 to $99.70 per barrel in electronic trading on the New York Mercantile Exchange.

Amazon makes life a little easier for PC users with Send to Kindle plugin (Digital Trends)

Kindle is great for books and all, but some folks would like to be able to get personal documents onto their Kindle or Kindle Library and up until now, it?s been a less-than-simple task. The option of a new plugin, however, is going to make the task a lot easier for PC users, and eventually Mac users, too. Send to Kindle for PC is a simple application that will allow users to easily send personal documents to both their online Kindle and their Kindle library for access on any Kindle-enabled devices.?

Once the plugin is downloaded, all users have to do is right-click on a document in Windows Explorer or look under ?Print? options in any Windows application. In both pull-down menus, a new ?Send to Kindle? option will now show up. After that, the documents are archived, meaning you can easily download them to any of your Kindle-enabled devices at any time. Conveniently, notes and highlights are also saved and will be the same across all of your devices. Make a note on a document on your smartphone and it will automatically show up on the document when you open it in Kindle on your PC. The only exception here is that the Whispersync notes and highlights won?t work with PDF documents.?

The new application is free to download and we have word that a version for Mac users will be on the way shortly.
