While many Americans will be relaxing after their Thanksgiving Day feast, many people around the world may have a shortage of food, particularly potatoes, a staple that is being seriously threatened by a disease called potato late blight.
In a news story appearing in the journal Science (Nov. 29), "Taking the Bite Out of Blight," writer Glenn Garelik examines the disease that is affecting potato production globally.
Potato late blight (Phytophthora infestans ) is the pathogen that infested Ireland’s potato fields in the 1840s, considered a major cause of the famine. Scientists had potato late blight under control in the mid-20th century, but in the past three decades late blight has spread around the globe, and the mutated funguslike pathogen has grown more tenacious than ever.

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...
