Scientists have devised an encryption method that thieves may not be able to stomach – messages written using genetically engineered bacteria normally associated with food poisoning. 科学家发明了一种加密的方法，能使已经成型的在细菌中的胃癌信息和食物中毒相结合。 Researchers at Tufts University in Massachusetts created strains of E.coli that glowed different colours when exposed to light beams. They were then put in a grid, with different colours representing different letters of the alphabet and the numbers 1-9, to reveal a short message. 在马塞诸塞州的塔夫斯大学的研究人员制造了关于大肠杆菌的菌株，当暴露在光束下的时候，能呈现出不同的颜色。当他们被呈现在网状的数字表中，依据反射在数字上的不同的颜色来褪色信息。 Professor David Walt, the study’s head author and a chemist at Tufts University, told Bloomberg: ‘It’s another layer of protection, a way of sending secure messages, preventing counterfeiting and providing authentication. 这项研究的主要负责人，这位塔夫斯大学的化学家大卫·瓦特教授，告诉彭博社说：“这其实是另一种意义上的保护，一种安全的传递信息的方式，能够防止伪造并为证明提供证据。” The message Professor Walt’s team wrote was ‘this is a bioencoded message from the Walt lab at Tufts university 2011’. |
