Antibiotic-resistant bacteria pose an ever-growing global threat, currently claiming the lives of at least 23,000 people in the United States each year. Research published this year shows that certain strains of a deadly, multidrug-resistant bacterium have now developed resistance to the last-resort antibiotic colistin.

That’s worrisome news, but scientists at Harvard University have discovered a weakness in the protective covering of most bacteria that could offer a glimmer of hope in the battle against superbugs.

Scientists in China announced this week the birth of two healthy baby monkey clones. Researchers at the Chinese Academy of Sciences in Shanghai cloned the infant macaques, about 7 and 8 weeks old, from a monkey fetus. The monkeys’ births are the first successful attempt to clone primates, showing that cloning humans could be theoretically possible, scientists said. “The barrier of cloning primate species is now overcome,” said researcher Muming Poo. But the team that engineered the monkey clones has no intent of trying to do the same to humans.

Three researchers, based in the U.K., United States, and Switzerland, won the Nobel Prize in Chemistry Wednesday for developing a technology that allows scientists to freeze and then document biomolecules mid-movement. The method, called cryo-electron microscopy, creates a detailed image, allowing scientists to see molecular processes never seen before. The development is like “the Google Earth for molecules,” said American Chemical Society president Allison Campbell.
