Luckily for us, the economically devastating Karnal bunt fungus needs personal ads and singles bars more than we do.
Airborne spores from the fungus, which damages wheat crops, are limited in how well they can start new infections over long distances, according to the findings from a Kansas State University project.
A phenomenon known as the Allee effect occurs when a small population of a species spread over a large area has little success in reproduction. The reason is that when individuals are dispersed over a wide area, it becomes difficult to find a mate. Like male and female humans, each Karnal bunt spore has something similar to a gender, and must find a spore with a different gender to reproduce. Karnal bunt has a larger spore that can reproduce on its own, but is heavier and less likely to be blown over long distances. It is the bunts lighter, airborne spore that needs a mate.

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...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
