A few years ago, researchers stumbled upon a fascinating discovery: certain bacteria, known as “cable bacteria”, are capable of emitting light. Now, scientists have taken this discovery one step further and have created a “bacterial laser” using these same organisms. This laser is made up of millions of cable bacteria, arranged in a 3D lattice, that are able to emit laser light when stimulated. The laser is the first of its kind, as it is created using living organisms. The bacteria are able to stay alive and stable in the laser for extended periods of time, making this a truly revolutionary discovery. With this new laser, the possibilities are endless, and the applications could range from communication networks to biosensing. It’s an exciting time to be alive and witness this bacterial party!
