Argentine researchers are part of an international consortium that is developing new drugs to combat antibiotic-resistant bacteria like MRSA (methicillin-resistant Staphylococcus aureus). The scientists identified a gene, FapR, which inhibits the synthesis of lipids—fats required by bacteria to build new cells. The research was published in the journal PLoS Pathogens.

Central and South American coffee exporting countries are fighting a new bout of coffee rust, a fungus that could damage more than 30% of the 2013-14 harvest. According to Nature News, Colombia’s National Center for the Investigation of Coffee in Chinchina is closest to a solution. Through crossbreeding, researchers have developed resistant strains of coffee which together with better weather predicting has reduced outbreaks of the rust. BBC highlights a plantation in Guatemala, a country which has pledged $40 million to combat the plague that has lost two-thirds of its crop.
Mexico’s aural landscapes—including noise pollution—are part of the country’s cultural heritage, says the National Sound Archive.

Mexico’s space industry is late to the game, says Mexican Space Agency director Francisco Mendieta Jimenez. Mexico’s aeronautics industry employs at least 35,000 people and Jimenez hopes this will grow to 120,000. He argues that telecommunications, defense, and mitigating the risk from natural disasters could all be improved by financing the space industry.
A burial chamber has been discovered in the center of the ancient Inca city of Machu Picchu.

Jamin has requested authorization to open the chambers.
