The theory of evolution has long been an interesting subject for scientists around the world, ever since Darwin’s proposal. Many new findings have shaped our understanding of evolution and some have changed what we knew thus far. Now a new study by scientists on fruitflies might further change how we have understood the importance of ‘trade-offs’ in evolution. The study has discovered that fruitflies develop immunity to a type of bacteria over a few generations without losing any other desirable trait, prompting scientists to believe that they have obtained immunity for free, a concept that was always associated with trade-offs.
Escherichia coli, a poster boy for microbiology research and the notorious bacteria that causes stomach infections, might soon be an unusual source of inspiration for us, humans, for learning how to handle stress! A new study by scientists at the Indian Institute of Science, Education and Research (IISER) Pune, has revealed, for the first time, that E. coli cells become more sturdy and fit when exposed to unpredictably fluctuating environments containing high levels of salts or chemicals, or having extreme pH values. Led by Prof. Sutirth Dey, the study aims to investigate the evolution of fitness and the costs incurred by the bacteria in this process.
