Bacteria feel pressures to evolve antibiotic resistance and other new abilities in response to a changing environment, and they react by stealing genetic information from other better-adapted types of bacteria, according to research published in Nature Genetics today.
They do this through the bacterial equivalent of sex, otherwise known as horizontal gene transfer, through which bacteria obtain genetic material from their distant relatives. This allows them to evolve the networks of chemical reactions that enable them to do new things, such as defend themselves against antibiotics or antibacterial sprays.
In the first ever systematic study of how bacteria change their ‘metabolic networks’, researchers have been able to piece together the history of new metabolic genes acquired by the E.coli bacterium over the last several 100 million years.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
