| Pico-world of molecular bioscavengers, mops and sponges being designed Sep 6th 2013, 00:30 A new world of molecular bioscavengers, sponges and mops is now closer. A computer-design method has enabled scientists to build proteins that can recognize and interact with small molecules. The proteins can also be reprogrammed to detect and unite with related substances, such as different forms of steroids. The method might also become a way to give organisms new tools to perform biological tasks. | | People who lie while texting take longer to respond Sep 5th 2013, 15:36 Ever been trading a flurry of text messages when there's an awkward pause?
