Question: "Petrocaribe will be strengthened -- independent of the international situation  independent of the price of oil " Venezuela President Hugo Chavez said as he arrived Friday in St. Kitts.
 His country's state Bolivarian News Agency said Petrocaribe leaders meet "with the expectation of its expansion  as well as new programs of cooperation and attention to a world increasingly thirsty for fuel."
 During the meeting  Chavez called the pact a geopolitical and social "offensive for unity " and said Venezuela is open to accepting other nations. "If some countries want to join  the doors are open " he said.
 The plan promotes Chavez's vision of regional independence from the United States  and the lure of cheap oil has drawn countries friendly to Washington as well as his leftist allies.

Question: "There have been different schools of thought on what this disease was. Could it have been plague? Could it have been typhoid fever? Could it have been a litany of other diseases?" says  Kirsten Bos   a molecular paleopathologist at the Max Planck Institute in Germany  and an author of a new study published Monday in Nature Ecology and Evolution.
A new algorithm allowed  Bos  and her team to identify fragments of ancient salmonella DNA with extreme specificity.
"It was an analytical technique that was really the game-changer for us "  Bos  explains. While scientists have been able to extract ancient DNA from bones and other tissue  until recently it was impossible to compare that extracted DNA to a wide variety of potential matches.
But a new computer program called MALT allowed them to do just that. "The major advancement was this algorithm "  Bos  says. "It offers a method of analyzing many  many  many small DNA fragments that we get  and actually identifying  by species name  the bacteria that are represented."
 Bos  and  her  team used MALT to match up the DNA fragments extracted from teeth of epidemic victims with a database of known pathogens. The program didn't entire save them from mind-numbing work — at one point PhD student and study author Ashild Vagene had to go through the results of the program by hand.
