| One team of researchers has discovered fungi that "eat" radiation, in a twisted version of how photosynthesis happens in green plants. "Our research suggests that melanin can use a different portion of the electromagnetic spectrum—ionizing radiation—to benefit the fungi containing it," said Ekaterina Dadachova, one of the scientists on the project. We'll talk to her about the discovery. A team of scientists reports that they are one step closer to crafting tiny biocomputers that could tap into a cells' signals and pick up signs of trouble. They've built a device of DNA, RNA, and proteins, that can perform logic operations within a culture of liver cells. "These biocomputers can translate complex cellular signatures, such as activities of multiple genes, into a readily observed output," said Kobi Benenson, one of the scientists behind the work. "They can even be programmed to automatically translate that output into a concrete action." We'll find out more. |
