Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of life on Earth. The research answers a long-standing biological question and could have implications for the timing of drug delivery, biotechnology, and how we develop timely solutions for crop protection. Biological clocks or circadian rhythms are exquisite internal timing mechanisms that are widespread across nature enabling living organisms to cope with the major changes that occu...

Bacterial bioclock Researchers have used the bacterium Bacillus subtilis to shine a light on internal clocks. Credit: Ákos Kovács, Technical University of Denmark The ebb and flow of our daily lives revolves largely around our sleep cycle, which is governed by our body’s biological clock. Other animals and plants also have these internal timing mechanisms to cope with light changes across days and even seasons – and now researchers have discovered that bacteria do, too. “We’ve found for the first time that non-photosynthetic bacteria can tell the time,” says lead author Martha Mer...

Date Time Bacteria can tell time Humans have them, so do other animals and plants – now research reveals that bacteria too have internal daily clocks that align with the 24-hour cycle of life on Earth. The research answers a long-standing biological question and could have implications for the timing of drug delivery, biotechnology, and how we develop timely solutions for crop protection. Biological clocks or circadian rhythms are exquisite internal timing mechanisms that are widespread across nature enabling living organisms to cope with the major changes that occur from day to night, even...
