Escherichia coli bacteria are the workhorse of microbiology labs. These bacteria move through fluids by spinning their flagella — a clump of tails driven by a molecular motor in the cell walls. Because the flagella spin one way, the body spins the other to keep it from tumbling as it moves forward. For decades, physicists...

Photobiology: speeding up enzyme reactions in microbes using light

We know photosynthesis is a feature of plants which absorb sunlight and use the energy to convert atmospheric CO2into glucose. While sunlight peaks in the 400-700 nm region (of wavelengths), scientists have shone ultraviolet radiation (well below 400 nm) on plants and found that this opens new avenues in enzyme engineering and drugs through photocatalysis...
