Pseudomonas Speedometer On The Job (IMAGE) Princeton University Caption A team of Princeton University biologists and engineers led by Zemer Gitai bioengineered a real-time bacteria speedometer by linking a flow-detecting gene in Pseudomonas aeruginosa to one for illumination. The faster the flow, the brighter the glow. Interestingly, the flow detection is independent of force, prompting new questions about how bacteria sense their environments. @PrincetonMolBio @EPrinceton Credit Illustration by Matilda Luk, Princeton University Office of Communications Usage Restrictions Editorial use only License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
