While the medical community has been exploring the use of bacteriophages, a form of virus that can be used to manage bacteria that have become resistant to antibiotics, plant pathologists with the American Phytopathological Society (APS) now say that this same approach may also help fight plant disease.
According to Jason Gill, a phage researcher at the University of Guelph, Guelph, Ontario, phages have been proposed as plant-pathogen control agents in a process known as phage therapy--the application of phages to ecosystems to reduce the population size of bacteria. "Phage could be explored as a biological control agent--the use of one organism to suppress another," said Gill.
Like other methods of biological control, one advantage of phage therapy is a reduction in the usage of chemical agents against pest species, which, in the case of phage, means a reduction in the usage of chemical antibiotics, said Gill. Another potential benefit of phage therapy is that phages are generally quite specific for their host bacterial species, and so can be targeted towards harmful bacteria while leaving other, potentially beneficial bacteria intact.

‘Spying’ on the hidden geometry of complex networks through machine intelligence

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
