All living organisms are dependent on water, but this is especially true for plants. Limited access to water is one of the decisive factors for humans to be able to survive in large parts of the earth. The development of plants (crops) with greater tolerance for drought is of great importance for more people to be able to live a decent life.
In a pure basic research project, where the goal was to understand how cells regulate protein expression, scientists in Umeå have now taken a giant step forward on the road to developing plants with greater resistance to drought, infections, and high concentrations of salt. By deactivating a gene that codes for a protein that is part of the so-called mediator complex in the plant mouse-ear cress, the researchers have shown that these plants evince a much greater ability to survive drought. At the same time, they have stronger resistance to high salt concentrations and their blooming is delayed, which indirectly leads to increased leaf production.
The research project is a collaboration between scientists at the Department of Medical Biochemistry and Biophysics at Umeå University and the Department of Forest Genetics and Plant Physiology and the Department of Microbiology at the Swedish University of Agricultural Sciences (SLU).

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...

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...
